In this video, I am going to show you, how I made a 9,5m by 4.25m concrete pool by myselfe in 1200 hour, spending around 4100USD.
I have tried to put together a detailed and interesting video.

I don’t think I’ve ever seen anyone else who deserved a pool more than you sir. Incredible work
I made one 3 years ago all by myself.
@@lothairelauwagie8758where’s your CZcams video though?
ok no problem i will put it on you tube.
@@lothairelauwagie8758 Musa faked Pamela on a deserted island. They sit by the sea, and Musa is sad and dissatisfied. Pamela asks him, "What's wrong, Musa? Why aren't you happy?" Musa replies, "Well, I am, but there's no one to tell to." 😎
So you dont have that pool my friend.
Yes i have ;-))))@@circumcisio10
The moment he traded $500 for 3 months of his life digging a hole, I immediately liked, subscribed and watched the full video......I am thoroughly satisfied....thank you brother, I never thought I would enjoy a nearly 10 min straight video of someone digging a hole....but here I am.....ready to watch another!!! Thank you brother xx
$4,128
That's next level cheapskate love it 😂😂😂
@@Sandman03777 I am referring purely to the decision not to hire a digger that would have took a day or 2 and instead HAND dug it, to save $500.
And I'm saying I respect that decision so much, that I watched his whole video, liked it and subscribed to watch this glorious and stubborn man give up months more of his life out of pure spite of not wanting to give his hard earned money to someone else for something his own hands can do....albeit 3 months slower lol
Ditto
I agree 100%!
Now this is why CZcams was created right here. Enjoy that pool sir. You deserve it and earned every relaxing float/swim in it.
1.000.000.
Oh My God. One million views. Wow. That's a lot. So far, you have watched my video for 18 years during its 210 days. (watchtime) During that time it brought almost 4k subscribers. And the price of the pool is almost back. This was my goal when I started. Everyone looked stupid, except for one person, that I would have a pool for free. ( THX Szmol... :D and K.K ) I was just right. :) This year, I'm going to spend a lot of time on CZcams. I'm shooting the pool upgrade video now. I hope it will generate a tenth of the views of this video. Thanks for all the views and comments. One step closer to my dreams of becoming a CZcamsr. :)
pin this, more people will see your second video that way
I agree with the other guy, amazing video you should absolutely pin your comment
Thank you very much for the many views! With 380k views, it is the second most viewed video on my channel. My video already generated 15% of the price of the pool. I am very satisfied. And thanks for the many views! I hope this video also crosses 1M views. I'm going to be a CZcams star and quit my miserable job. I took a big step towards this! :) Next year I will do my best and reach 100k subscribers!
You will do it. I watched a couple of times and left a few comments to help the algorithms. Loved the video and the way you use the English language. Many cute comments. Good luck to you.
Excellent job. Love the idea of a separate chamber that's big enough to climb into for maintenance of the filter and pump. There's a few things I'd have done differntly. Those lights I'd have used a pipe going right through the wall, that leads to a separate bay. That way if you ever need to change the bulb, you'd be able to access the lamp from outside without any need to lower the pool level. But since you've used LED lamps, the probblem likely won't arrise.

Good luck in achieving your dreams, having watched you dig the pool out by hand, very impressive, and not giving up, I’d say all your dream's and wishes, will be more than achievable, just subscribed, hope to see you at the 100k, and you break the 1million mark,🍻from🏴🥃.
You said in 2 places of the video that the pipes under the concrete broke after the cement was already poured. But near the end, you connected the pipes to the pump anyway. Did you tear the cement up and replace the pipes? I think I'm missing a piece of the puzzle here.
849k views now. You're closing in on 1m!
Two things I've learned here, a mans willpower and dedication can lead to amazing results. Also, rent a mini-excavator when you have lots digging to do. :D
I came here thinking about DIY'ing a pool. And I now know i will just hire someone. lol.
He did alot of work but I don't think it will last. The rebar for one does not look adequate.
“I Hired free labour….”
Love the humour and the lessons learned.
Thanks for this great video
This is the MOST HONEST DIY VIDEO on the internet 💯
This is dope.A man building an entire pool, mostly by himself. The main thing I love about it is he never half-assed anything and it shows in the end results. Nice job, brother.
This was really satisfying and therapeutic to watch. Granted, I thought you were absolutely nuts digging for three months, but after all that blood, sweat, and tears, you deserve this beautiful pool more than anyone. Fantastic job. I hope you make many fond memories with family and friends around that pool.
Also, as an owner of a swimming pool company, one suggestion I have is adding a main drain, at the lowest point of the deep end, if you could have done it again. Again, great work!
How exactly would he do that? I'm just curious
Wow he really dug his pool by hand. That's impressive.
You are a true hero. I also live in Hungary and dug a 40 m³ pond myself. The summers are very hot and the soil (sand) is often as hard as concrete. After digging such a big hole you know what you have done. You really did an amazing job! 👍
_Doesn’t it rain in Hungary?_
@@michael.forkert Hungary is located in the Pannonian Basin or Carpathian Basin, the remnant of an ancient lake that dried up 5 to 10 million years ago.
I live almost in the middle, where the land is quite low. Due to climate change, only 8 to 12% of the annual precipitation has fallen in recent years. It's different at Lake Balaton because this region is close to the Alps and naturally has more rainfall.
Climate in Hungary is more diverse as for example in Germany.
@@WhereIsTheSpartan I’m Brazilian. Thks for the explanation. But I do not believe in Global Warming, Greenhouse Effect or recently re-baptized Climate Change. Here in São Paulo the climate changes every other hour. Today at noon 36° now at 4pm 24º and falling.I do not believe that anybody has the ability to know what happened millions or billions of years ago.
@@WhereIsTheSpartan The Alps don't even reach Hungary, even less Lake Balaton. www.google.com/maps/place/Alps/@47.4737594,11.7913777,600831m/data=!3m1!1e3!4m6!3m5!1s0x4789459fb534be51:0x38c7fdcd674c57d!8m2!3d46.8873983!4d9.6567822!16zL20vMGxjZA?entry=ttu
I didn't hear you mention but hopefully you used stainless screws/nuts etc. where needed. You could sand the fiberglass to make it smoother (might have missed that part too if you did). I'd add an area at least 4 feet wide all around the pool to walk on so that dirt and grass don't end up in it. Even a wood deck would be good, save your filter system.
Hope ya had a good summer in there. Good job man!
🇨🇦
All very great valid points! Much love from 🇺🇸
I kept thinking he needed a walkway around all through the build. You’re gonna’ be constantly skimming to keep grass out, I think. I’m sure something like this and landscaping could be added for years to come. What a beautiful job, overall. What dedication and logical thinking!
Cement deck would be good.
Dr. Daniel is a throwback to the best of humanity
You do really need to do a follow-up video with what went wrong and how did you fix it. Like the leak at the lamps you mentioned. This will be very interesting and get you even more viewers! Great job on that DIY-pool!
I am absolutely impressed by the way you strategised everything showing alot of compassion towards this project. I find that your motivation and fantastic workmanship is a rare find these days. Congratulations, your pool looks amazing.
Congratulations, a young man with talent and conviction that nothing stop him to accomplish his dream. Is rare to see this character today! thanks for sharing.
I cheered when that pool got finished, strong work!
Great job bro. Never in my life have I seen one man dig a normal size pool with shovel and wheelbarrow Kudos to all your hard work. Pool looks great. Hope you and your family enjoy it for years to come.
Nice work. My dad let me and my brother build a pool/pond. Took us 2 years every day after school. But we live out in no where in Ohio, so we didn’t have to worry about a government official telling us what we can do on are land. Keep up the great work.
How did the pool/pond turn out? Any pictures you could share?
*our
Back in the states we love this do it yourself stuff. Excellent work.
My Dad had an in ground pool originally built with a vinyl liner in his 60’s. Instead of using the company who built the pool when the vinyl died he decided to build a fix himself.
So he then had a hole in the ground as you did, he also built the walls using cinder blocks.
Back then there was not a way to use the fiberglass as you did. (Great ideas by the way) I do not remember what he did for that part. He used Portland cement as it makes a whiter finish than regular concrete. He did paint his white. He was lucky to already have the pump, plumbing, etc.
They really enjoyed it for years.
Your home is your kingdom, and the pool is your throne.
The spade is my scepter!
I love this. Taking control of your dreams and accomplishing what you desire. You identified your goal and worked to make it happen. I can only assume at least 1 person tried to discourage you at some point, but you overcame all obstacles. Excellent! I am sure this will lead to even more steps on molding the life you want to live. Congratulations.
Worst case scenario, I have a pool. The mindset behind all my diy projects. Sick job. All the props to you brother. Can’t say enough.
My back hurts watching you shovel. What dedication
Wow. This is one of the most incredibly complex DIY projects I've ever seen on youtube. Bravo.
Gave you a thumbs up. You have a wonderful sense of humor and I love your charming use of the English language. My favorite...."After three months I had a big hole in my back yard." Hope your channel grows and grows.
Thank you great job good things take hard work.Beautiful country. Im thankful for you tube for making it possible for us to know our brothers in a different country.Just starting to learn how to properly use the internet ,again thank you and enjoy your great creation.
HUGE RESPECT to you for hand digging your site…
VERY inspiring!! You should make a deck around it (something small to isolate it from the rest of your garden, you can also fit a coffee table with some chairs for nice breakfasts)
I watched every minute of this video. I can not believe you actually dug that out by hand! Nice job and congratulations. Excellent video sir.
Absolutely amazing. Just the pure patience you have. God bless you!
What an amazing project, it was absolutely incredible, I had a cinder block pool and it had 1/2 inch padding and a drop in liner, but that liner was $2,500 to have made and installed, and that was 20 years ago, well done sir.
Very impressive! I was unaware that dry stacking of concrete block would actually work, but it clearly does. The only thing I would do differently is to add a bullnose profile on the leading edge of the concrete steps. Having done countless concrete projects in my lifetime, I know what hard work it actually is. Dr Kun Daniel makes it look easy, a testament to his very impressive expertise!
I'm also surprised by the dry stacking, it gives me several ideas. Great job, you have to be really determined to achieve stuff like this.
it works but its better to glue them down, that way you can get them leveled, something dry stacking wont.
There is a process called surface bonding that allows for mortorless bonding of blocks. The first course is bedded in mortar and leveled. All other courses are dry stacked and leveled with small shims of wood or even paper. After they’re stacked they’re soaked with water and they’re then parge coated with a layer of surface bonding cement made of Portland cement and chopped fiberglass. You can make your own or (here in the us) buy it from the home center. You can coat just one side but two sides are more than twice as strong. It was originally developed for water proofing cisterns.
Thanks for the info, very helpful!@@jamespayne8781
I too wanted to suggest a bullnose edge to finish off his beautiful pool!
i think it came out great, for not being a professional pool builder. it's great. you have a few small things to work out. but you have a great foundation to build on. I don't know if you thought about this yet. but you can always tile that pool.. it will clean up the block work you mentioned. and also water proof it more. they have a liquid membrane that you can roll on to the walls and the floor. then you can tile directly over it. I know it's an added expense but you can do it maybe next year. but all the hard work is completed. enjoy your success.
Can he tile it directly over the fiber glass? cheers
Fiberglass for a pool liner. Now that's thinking outside the box. The whole project is very impressive.
Man you are a legend ❤️🤌🏻 I hope your knee is doing better 🙏🏻
Wow, such a wide pool with plenty of swimming space to enjoy!!
Great work man well done!!!! Been saying to the wife for ages I can build our pool out of concrete blocks, formwork carpenter here. I've just bought a 1T excavator I'll be using to do basically the same as what you've don't. Well don't mate from Queensland Australia.
Thanks! Good luck with your project! :)
Your dedication to this was awesome to watch I'm not sure there is too many people that would dig that hole let alone all by themselves!
Hand dig? BEAST MODE ON! 💯🤙🏾
I probably wouldn't DIY the electrical, but after thinking about it, you're probably at low risk because you generally won't be in a position to complete a circuit, so even if there is an electrical fault you might not even feel anything. The thing I would be scared of is the wall collapsing (cracking), especially without any gravel backfill, but maybe keeping the pool full of water will provide enough counter pressure it's not a problem. I love the idea of using fiberglass, but I'd be worried about the resin lasting in the sun even with a UV resistant formula. I really enjoyed the video, I hope you make a followup in a year or two just to say "hey everything is still working".
The boat is made of the fiberglass I use. UV stable for decades. Looks good so far. I thought the resin would separate from the concrete. He could not. 220 V lighting cannot actually form a circuit with its contents. And the leakage current relay disconnects all problems immediately. The water in the pool has the same potential as the soil. But I got a negative comment, so I would rather change it to a 24V or 12V system.
For whom it may concern: Fibreglass with Top Coating is pretty common in Europe for swimming pools. BUT.... DON"T use BLUE top coat! It may sound kinda strange, but use WHITE (RAL9001) top coat color! Once filled with water it will look like a tropic ocean!
Yeah the color looks weird.
😂😂wow the end was the best happy swim 🏊♀️
This is the coolest video I've ever watched! You are a superhero!
Amazing job - congratulations on your hard work and great design!
Csodálatos munka - gratulálunk a kemény munkához és a jó mérnöki tervezéshez!
What incredible commitment and work ethic!
The stairs are so beautiful! You put so much work into this project. Thank you for teaching us!
Love this dude straight savage 💪🏾💪🏾💪🏾 got me outta bed after I saw this too 😅😅😅
Well done and I enjoyed watching every single minute of the build. By the way I'm watching from USA and I don't think the land of the free would allow us to build our own pool the way that you did with how ridiculous building codes have become here. I sincerely hope that you get to enjoy the fruits of your own labor for many years to come. I applaud your hard work and dedication 👏
If you make it look like a pond you can bypass lots of stuff :) Atleast thats ewhat I'm hoping as i dig mine haha
I’m not gonna live somewhere wer I have to ask permission with wat to do on my property. That’s y I live n the country
Great job! I like it a lot.
Need to add some concrete pavers around the outside of it I think though. It would really reduce the amount of grass & dirt getting into the pool :)
Be a nice aesthetic too.
Yes, this is indeed a problem. And I want a durable cover for next season and a square cover in the future
Most realistic DIY pool video
"Why not make a video out of it? Worst case scenario, I'm gonna have a pool."
LOL love the spirit
This is Amazing! 👍
Well done, you did an incredible amount of work!
Your pool looks amazing. Well done! Even if it is a year overdue because of your broken leg, it is still worth your time and effort. A lot of hard work now gives you a very cool reward in the Summer time. 😉👍
Much respect goes out to you for the amount of work you put into that project. Well done, and well deserved.
❤ WOW! You are so hard working! I can't believe you dug it out by HAND! GOSH!😢😢😅😅 It has turned out BEAUTIFUL! And I love the placement in your yard in relation to your home and view! love the video. Very very good. And, you have such a deep, manly voice, very easy to listen to. Hello from Colorado, USA!🎉
Great job....but why didn't you use low voltage LED's? Those are 110/220V no?
Yes, I know, I received a lot of criticism about the 220V. As an electrical technician, I do not consider it any more dangerous than the circulation pump, but I will replace it with a 12 or 24 V one.
Most people would have given up after they shit their self, but you sir powered on!! You can tell a lot of hard work went into this, outstanding job!
"worst case scenario, I'm going to have a pool." Gold. 😅
I just gave you a thumbs up for digging the hole by hand 😮
Fascinating that you didn't use mortar to lay the blocks. You just stacked them and poured them full of cement. Interesting concept for construction that I have never seen done like that before.
That's exactly why he got the leaks lmfao. The mortar acts as a sealant as well as a binder.
Also no sloping to the deep end. Just flat bottom and that was why he put six drains along the bottom. I think those pipes froze and broke under the slab but he didn't want to discuss it. One drain in the middle of a sloping deep end is the best method used for pools.@@JonezBBQ
Formwork stone is not laid with mortar. This is not a brick. Here, the bond is provided by the concrete in it. It does not need to be sealed with any mortar. Here, the waterproofing layer is not concrete, but fiberglass. Concrete only has a supporting role. The pipes are frozen at the bottom. Then I made a new branch. There will be a video about it.
Lots of hard work to be sure but with amazingly beautiful results. Love your budgeting. Here in Canada that is a 14,000 to 20,000 dollar pool. Good video as well. Thanks for posting.
In Canada? I think you could add a zero to those figures for real!
14-20.000 not enough Buddy min 40-50.000!
Шикарный участок и басик!
Great job for that small budget, a tip: don't amp the pump up to 10m³/h, the pressure in the sandfilter will be too high causing it to wear faster and most importantly the filtration of the water will be decreased since you're sucking the water through the sand much faster and with higher pressure, it will create channels in the sand. It's better to filter at 7m³/h for longer hours.
I'm always very envious of all these DIY people on CZcams who have have easy to dig backyards. I even think about digging in my back yard and 3 of my shovels and a mattock break. My yard is practically solid rock at roughly 400mm down so I can't dig too far unless I have hired machinery. Outstanding effort by the way, Ripper of a job!
I'm almost offended that he complained that digging was difficult. The soil in his yard is practically pure clay.
@@K1L0W0G You want clay? You should see my city in NZ. This soil looked like the perfect sand/clay mix for digging.
Yep, that soil is butter.
I live in Florida. where Im at anything below 12"-22" is fossiled coral rock, aka limestone. Like, Ive installed a fence where we pulled a 4-1/2" x 5' foot limestone boulder and had to pickaxe it into smaller chunks to then refill around the post hole so the soil around it wouldn't collapse. Digging here, even with an auger is a giant pain-in-the-ass.
A man with a vision.
And a shovel.
Watched the whole hour, was like a movie with a cliff hanger of what went wrong. As a builder myself from the UK i can honesty say you deserve this pool. 3 months digging a hole, the comment on cutting corners while actually cutting a corner was brilliant. Our land here is so rocky, soily and thick clay it would break anyone after a week. We cant knock earth probes down that easy too with such a small hammer. But you got the heat which would be insane to work in everyday. Great video. I dont feel like i spent a hour.
You are a talented guy...not sure about the safety of the homemade lights but I wish you the very best. That took a ton of hard work.
They're actually the safest part of them all. I can't imagine what it took to solve fiberglass leaks
Awesome. love your vision and perserverence to just get it done. I wonder if your concrete estimation shortfall included multiplying by a factor of 1.3 for wet volume vs dry volume of materials.
Yes, the referenced m3 values do not refer to dry material. For example, about 9m3 of concrete went into the foundation. This required about 11 m3 of gravel and 2.8 tons of cement.
You are a beast man . I can't believe you mixed that concrete by hand ..
A dream, a passion, ingenuity, a ton of hard work, persistence and pride. I am completely impressed. I also am not ashamed to say that there is no way in hell I would attempt it. You can take great pride in a project well done.
Respect to your dedication! I think I would have reduced the size immediately after digging for a couple of minutes. Either to save Material to rent a digger, or at least to dig less. :D
Subbed and liked, thanks for making a video of your Project
Nice and I hope this goes viral as well 😊
Thank you! :)
Most amazing video I’ve watched in ages, well done! Brilliant bit of work
Im glad people like you still exist 👌👌😎
Nicely done. I would have done certain things differently, but it doesn't matter, you nailed it.
The ONLY thing I must comment is that covering the whole pump space with concrete and leaving only a small manhole was not the best idea. I would have covered it with a larger manhole cover (I see you managed to do it for a smaller one).
But yeah, I congratulate you!
Yes, this also gives me a headache. I got an acid container from which I want to make the sand gravel. The diameter of the container is 65 cm and the expiration date is 58 cm....
The home made lights are not that safe I would have liked to see lots of silicone used for the two holes in the cup to run the plastic insulator. Still I would run a very low truck battery voltage on that pool wiring for the lights with a GFCI circuit in case water were to penetrate the wiring then nobody would be electrocuted to death. Never cheap out on electrical for pools where water is concerned and people and kids going to swim in it.
I received a lot of criticism for the 220V lighting. As an electrical technician, in my opinion, it is no more dangerous than the circulating pump. But I will replace it with a 12 or 24 v system.
@@kundaniel I agree, good choice🙏
Wow, Wow, Wow, you did an absolutely amazing job at building your swimming pool all by hand!
Your design was exceptionally perfect and I cannot wait to see the next part of your pool project!
Well done, Sir!
You are an inspiration to all DIY builders. Thanks.
Amazing. Sure i will follow this when im building my own. Though i would make the stairs not this wide
Már megörültem hogy kommentet kaptam. :D
My narrator's first comment is dearest to my heart.
Man i hope there is no fualt in the pool lights.... thats your life right there 😮....
I like it when people bring up this topic... In an interesting way, no one has been bothered by the fact that the circulation pump is also 220 as. However, it is still in contact with the water on the metal part and is present as an inductive load. It somehow doesn't bother people because it works silently. almost everyone mentions the spectacular part that lights up. Please tell me what happens if the phase gets on the water and someone is inside... Nothing. There is full PE coverage with separate earthing probes with life protection relay. But if they weren't there, no one would be electrocuted even if one of the phases was exposed to water. However, the water has a one-to-one ground potential, even though there is a plastic pool wall, everything is connected to the ground probe in the case of metal parts. I am a high current electrical technician. Obviously I'm not going to make my own pool life-threatening...
@@kundaniel The pump isn't isolated by a home made enclosure from pipe.. Use LEDs please. 12v LED should be safer
That (Reward)Canon ball was classic 👍
Congrats you're a professional shovel master.
What happened to the water at the end of the video, its brown?
Fresh well water has a high iron content. 1 week and the filter takes it out.
Mate, WHAT is with the murky water at the end? Do you ever chlorinate that pool? or do you rather bathe in algae and... I don't even want to think 😂
😂
A healthy pool
Looks like lake water
Looks like lake water
Beautiful pool. Enjoy!
A+++++++ for thought, ambition, & energy. Amazing project, enjoy it for many years.
congratulations, a great achievement and we all appreciate the information you have provided with this video. Some of the comments have made good suggestions to enhance the results but you did the majority of it , and therefore respect! With the pipes breaking due to freezing, what did you do to fix the issue? Do you seal the ends with a plug and drain the tubing, leaving them with air , not water? Thanks from Australia.
I'm also dying to know more about the broken pipes in the concrete!!
I built a new branch from the shaft to the last step. 2 40mm KPE pipes lead into the ground next to the pool. I plugged the old pipes and covered them with fiberglass. But I left one to drain.
Piece of advice from a pool man: Don’t attempt this safety is always an issue. If the wrong materials are used you could also contaminate the ground water. There are materials you cannot use for this consult a pool builder. Your city has to inspect this construction and most will not allow you to build a pool without a contractor’s license. This pool will eventually cave in or float. The piping will kink when the ground shifts. And the grey pvc will get brittle and will crack. The metal piping will be eaten up by the chlorine and the acidic rain falls. This construction will cost this guy thousands of dollars when it does fail.
But......he has a pool😅
@@Ahmadandwoods he has a health hazard. When people. Start getting sick then he will pay.
Having dealt with pool builders as a contractor i can tell you a significant portion of “pool guys” basically run a racket in their region. Pool engineering is basic math, do some research online for materials ect.
How many pools by “contractors” are total SH..E? A lot!!! Pools are like boats, except pools take you nowhere and always fail one way or another.
😂 I’ve seen pools built with concrete blocks icf blocks some fiberglass
I think he did a better job than I seen
I’m dumb my dad made us a cement pond to play and cool off in from the left over pits we made for the drilling mud when we drilled our water well, so that was fine.
Well done. Thank you for sharing.
This is simply unbelievable!!!
You sir are an incredible skilled person.
Hope your leg healed nicely by the way.
"worst case scenario I'm going to have a pool" 16:15 😂😂 brilliant!

Nothing about this video is boring sir its quite education and satisfying. Stimulating to ones mind....🤘🏽🤘🏽🤘🏽🤘🏽💯💯💯🇯🇲🇯🇲🇯🇲
I absolutely enjoyed watching your pool creation. Thank you for sharing.
that is amazing. a lot of work.
