How do I fix my bathroom floor?
+2
I bought a 100yr old home and in the full bath was carpet(why I don’t know) but after one of my 10 kids flooded the second floor bath/hall water was dripping through cracks of the first floor ceiling. I pulled up the carpet to find sheet lynolium that I have mostly up to find a white membrane after peeling up most of that. I found rotted hardwood. Now I’m at a loss for what to do next.
I would check out the subfloor. If that's rotted too, then you have to replace it all. To do that, everything has to be removed from the bathroom. Sink, tub and toilet.
Tear up the whole floor, remove toilet and possibly the sink, replace with thick ply wood then some lanolium!!
I don't think this is likely to be a diy project. Just looking at the photo the damage has been going on for a long time, and the leaking that caused this could come from the toilet, bathtub, sink or pipes in the wall. I would find a reputable contractor to come in and find how much damage there is to joists, subfloor, maybe even walls and what needs to be done to fix it. The carpet was probably to cover up the damage, but may have even contributed to it. You don't want to be sitting on the toilet only to find yourself suddenly sitting in the living room. Best wishes.
It's not an easy fix but if your good with tools you may be able to do the job. You will need to remove your sink, tub and toilet, then begin removing the damaged/rotted wood. If the joist are not completely damaged you may be able to "sister" new ones to the damaged one by connecting them to the wood that is still good. Once the support beams are solid then lay down 3/4" plywood and on top of the plywood lay down waterproof backer board. Finish off with vinyl or ceramic tile.
Take up a the rotted hardwood and see how extensive the rot is. If it is through any sub-flooring, you will need to cut out all the rotted floor and check the joists.
If there is rot in the joist, you will need to call in a professional. Unless you know what you are doing and have some help, this is a job to call for "people in the know!" Remember, the joist are holding up the house...and they will have to be shored up before any repair and/or removal can be done. It may be that you just have to replace a small section but you will need to know how to tie the new joist sections to the old sections. (consider using bolts if you splice the joists and maybe adding a footer with reinforcement pillars under the new sections.)
If the rot is confined to a small area, follow the advice above.
The more you can remove and put back in place, the less expensive it will be..BUT...make sure you have the foundation secured before moving forward!!
GOOD LUCK!!!
