- Hey guys, During our bathroom renovation I found that the subfloor was rotten and will need to be replaced. This seems to have been damaged from a long time ago and had been covered up. I will be tarring out everything damaged and replacing it. Check out the video to see how this is done. This video is #10 is a series I am doing on our bathroom renovation. Check out the links below to see how the bathroom is coming along.

Great presentation. Fast and info packed.
Thank you! I appreciate it!
Thanks. Exactly what I was looking for
So happy to hear that! I'm glad my video could help!
Omg. Why is your wife barefoot?? Good video. Awesome shes helping out too.
I know! I got after her for that lol :) Thanks!!
standing on screws or nails barefoot never a good idea!
I am in the middle of this same project, I was curious why you decided plywood instead of replacing with individual boards. Cost ? Easy installation? More structurally sound. I was going to replace each board but wasn't sure if there was any benefit or not from boards or plywood.
Well, plywood is more stable than individual board and can be easier to install at the same time. is you have only a few boards that need to be replaced you may just want to replace the damaged ones. However, my floor was in pretty rough shape and was better to just remove the whole section and replace with plywood.
Hope that helps!
Thanks!
I'm my region if you replace the boards with the same type of board then it is a repair and you do not need a permit. HOWEVER if I had to do his type of replacement this would needed to be permitted. So in my case I would go back with boards and not deal with the hassles.
How long did this project take? I’m going to start a project very similar in my bathroom, but it is my only bathroom so I don’t want it to be out of service for too long..
I finished this project over a weekend. However, the whole bathroom remodel took several months as I only worked on it during the evenings and weekends. after this remodel we had 2 full baths in our house so I didn't run into a problem with it taking a few months. There are ways to work around the toilet, shower, or sink to keep them hooked up till the last moment or when you're done for the weekend you can temporarily hook it back up to get by till you finish.
good luck with your project!
What type of wood are you using for your subfloor? I have never replace flooring before and I have no clue what type of wood that I should get. All I know is that the rotted wood was a half inch think.
I have attached a link to what I used. 7/16 maybe the closest thing to 1/2in that you can find.
They also have a plywood version of the subfloor as well. But both work well and add a lot of strength. The key is keeping it dry. if ether type is exposed to a leaking toilet or tub they will rot out over time.

Hope that helps!
Thanks!
Did that toilet backup? seems you didn't put a drain under it.
Isn’t subfloor supposed to have 1/4” gap around the floor edges and 1/8” gap on plywood seams for expansion?
I'm not sure about the edges but the seams between sheets are supposed to be as tight as you can get them. The seams are tung and groove, they lock together giving it more strength. I believe the chipboard subfloor is more stable than plywood and would be less likely to expand unless it's repeatedly soaked in water.
always done quality and elbow grease to get everything to Simon code!
Thanks!
So you do place a sub floor down and then another one on top...and how thick was wood did you use
Two layers are often used in places like bathrooms and kitchens where thin flooring like tile, linoleum or vinyl is used. The second layer of subfloor gives it more strength and helps the thinner flooring line up with thicker flooring used throughout the house like hard wood flooring. I used 3/4in subfloor but the thickness can very slightly depending on what levels the floor with other rooms.
hope that helps!
@@SimonSaysDIY thank you my old subfloor was 3/4 and it had 3/4 tongue and groove on top.... one more question what brand of plywood did you use
Are there additional videos for this bathroom?
Yes there are. I recorded each step and shared it to this playlist: czcams.com/play/PLJ459E_OzBRZXxSMqrNXMz7pdKvhciMue.html
Hope you find these helpful :)
did you insulate interior walls? just wondering...
Yes I did. The main reason for that is noise dampening. If the walls are hollow they can cause sound to echo and travel through the walls.
Dude i have the subfloor like urs, the planks were put on diagonally from the joists, terrible, most of the planks were left hanging past the joists and therefore cracked down the middle over time
Yeah it is a method they used a long time ago. I’m not sure if they did it to be cheaper or if the plywood wasn’t yet used. It has lasted many years but doesn’t seem to be a good way to do it.
Yeah i have the same thing also
Planks installed diagonally allowed the finished hardwood floors (which were the typical flooring option) to be installed perpendicular to the joists. If the subfloor planks were straight across the joists, then the hardwood would either have to go the same way as the joists (very undesirable, leads to wavy floors); or the hardwood have to go the same way as the subfloor (would lead to large gaps & loose squeaky floors as the subfloor shrinks). I'm about to rip up my bathroom floors, due to an undetected leak leading to rot. I appreciate this video as I don't find a lot of information on 80 year old homes.
Isnt the plank layer the subfloor Technically and youre just adding a subfloor layer?
So is this technically 2 subfloors?
Yes and no. It is common to have two layers below the flooring, especially in older construction and remodels. Typically plywood will be laid down to close in the framing. however one layer will work, a second layer of chipboard subfloor is much more stable and makes a more solid foundation for especially thinner flooring like tile or laminated floor. Unlike hardwood flooring that adds strength to the floor tile and thin laminated flooring gets its strength from the subfloor. I hope that helps.
@@SimonSaysDIY i think it does, i am currently demoing my bathroom and was expecting plywood, but found planks underneath it, which was rotted due to the toilet not being properly mounted. Saw the planks and was just kinda dumbstruck cause I've never seen it before lol. You think it'd be okay to pull the planks and replace them with a plywood sub floor?
Edit: I appreciate the response immensely btw.
@@mercenary1485 Yeah, I believe that would be perfectly fine. However, if there is any plank flooring leftover you will want to make sure it ends on a floor joist. On my floor, the planks ran under a wall and into another room so I had to cut them and leave them on the first joist I could get to because those planks were supporting the wall and the flooring in the next room.
Good Luck with your project! I'm glad I could help!
@@SimonSaysDIY thank you so much, I'll update if the house falls down lol
