We renovated both of the bathrooms in the Wingnut when we bought the house. They were basically gutted, and we had to redo the flooring and everything. We did hire a plumber to do the pipes because of the need for expediency.
We’ve been noticing that the floor in the downstairs bathroom has been looking like it has water damage, but there has never been water on top of it. We reckoned it was coming from below. Well, now it has apparently gotten to the point where we are going to have to confront the problem. I went into the bathroom two days ago, and when I stepped on the floor, water squelched up from the floor boards. No bueno.
Hopefully the problem is basically that the wax seal on the toilet is not sealed properly. That seems the likely culprit. Either way, looks like we get to tear up the floors again and re-do.
This time, if we get the leak fixed, I’m going to tile the downstairs bathroom with the tile leftover from the upstairs bathroom.
