bathroom subfloor missing - DIY Chatroom

mherman333 · 11-26-2006, 05:23 PM

We recently bought a house and have found a few things that the owner did not disclose to us. We had a leak coming from the master bath through the downstairs ceiling. Turns out the bath tub faucet piping was too short so we fixed that by buying a new faucet with an adapter. We decided to make sure that it wasn't leaking and went up through a vent from the downstars. The vent was just a cover-up for the poor bathroom remodel job that they did. They cut a 2 x 2 ft hole through the subfloor and we can see the tub etc. Should we be concerned that there is no subfloor and that the piping was not placed through the existing cyclinder hole in the subfloor?

Any help/ comments would be appreciated!

If I am understanding your post right....then my next question would be: Is any area of the bottom of the tub NOT being supported by the subfloor (weight)?

Yes there is an area of about 2 ft x 2 ft that is not supported by a subfloor.

If the actual bottom of the tub or an area of the tub looks as if it is not being supported, You can try to place pieces of plywood or shims between the joists and tub bottom.
Also: If you place cut-outs of the floor (Usually 3/4"), you can then place 2x10 lengths next to the exising joists to 'sister' them and 'lock your plywood into place under the tub.
If this is a fiberglass tub, you definitely want the whole area underneath to be supported.
Another means of additional support to other areas is spray foam (Plumbers use it all the time).
