I have a vinyl tile floor that is suffering form water damage next to the shower and is folding up. I want to replace the floor. I am afraid there is water damage to the subfloor as well. There is an obvious mold problem evident on the subfloor that is in view from the tile folding up. How do I tackle this project? I want to replace the floor and don't know how to begin with the subfloor. I am a first-timer at this do-it-yourself project and looking for your help! Thank you!

 

AimJas,

This may be quite an undertaking. The mold that is evident next to the shower will have to be resolved and you are right, removal and replacement will be necessary.

Not knowing what you have for a shower, custom or pre-built, the subfloor near and under this is probably damaged as well. It will be necessary to remove this or the mold and mildew will continue to grow and assuming that the condition of the subfloor under the shower will be similar to what you see now, the choices are none. I wouldn't even suggest just trying to replace subfloor next to the shower since it is obvious that the problem has been ongoing for some time. Even replacing a section may not be good since your linoleum will have to be stripped and new underlayment put down to ensure a flat surface. In some cases this means possibly raising the toilet flange and doors may have to be trimmed.

Partial replacement of subfloor is acceptable and then apply underlayment, then new linoleum.

Alternative is to replace all subfloor since the flooring will have to be replaced, you should just consider removing all fixtures, replacing the subfloor, reinstall the shower, lay new flooring. and reinstall all the fixtures.

Hope this helps!

 

Thanks for your helpful advice...wish me luck
