Unhappy Weekend Project Turned Bad

My husband and I started our weekend bathroom flooring project. We successfully removed the old vinyl flooring. We came to find out that the water from the shower/tub had been leaking onto and under the vinyl flooring. As a result there is mold damage to the subflooring around the tub. How do we repair or replace the subflooring? Do we have to remove the tub? Can you please send some detailed pictures on how to go about this task?

Hi & welcome to the forums. Hopefully we can get ya on the right track, but can't actually send pictures, sorry. There is however a link to library of how-to pages located here on the site. It's located right next to the DIY.COM logo located at the top left side of the page.

Now some general guidelines, if the floor is still very solid, (no give between the floor joists), still flat, with just surface mold, clean the area with a scrub brush and bleach diluted w/water. This might be the case if it's just splashing that caused it. Allow the cleaned subfloor to dry & you'd be ready to replace the vinyl flooring, although if it's within the budget, a layer of new 1/4" luan subflooring would be a good idea to insure you have a clean dry flat surface to lay your new flooring on.

But if there's actually been a leak, like from a pipe or the wax seal on the toliet, you probably have much more extensive damage and demo is going to be required. Depending on how bad things are, you may indeed have to remove the tub in order to make the necessary repairs, but in alot of cases it is only necessary to remove the toliet and possibly the sink vanity. To remove the subfloor, set the blade of your skillsaw so that it will just barely cut thru the subfloor, you don't want to cut any joists. Cut out squarely to the center of a joist and replace with like thickness of plywood subfloor, exterior grade is best in a bathroom, IMO.

Now if you're wanting some other type of floor covering, especially ceramic or natural stone tile, do post back before you proceed, as there are other very important factors to consider in that case.

We really need some more info to give any meaningful advice that is applicable to your situation. The more info you can provide us with the better responses you'll get in return. How badly is the subfloor damaged? What kind of material do you have there now, plywood, osb, 1"x planks? Also what is the plan for the finish flooring surface, vinyl tile or sheet goods, ceramic tile? Another thing is where is this water coming from, is there an actual leak coming from a supply line, or is just from water being splashed or sprayed out of the tub, or is coming from the toliet?

Pics can't be posted here directly ,but they can be uploaded to seperate hosting site & a link to them posted here and sometimes will speak 1000 words. Click on the announcements at the top of this forum for further info on how to do this, let me know if you need further instructions on photo hosting.
