When my wife and I bought our current house, I noticed 2 issues with the tub. First, the vinyl floor around the tub was peeling away at the edge where it meets the tub. I pulled back the flooring a little, and noticed what looked like water damage on the underlayment. I pulled that up, and saw some water damage on the subfloor. See the pictures I posted.
The other issue was the control for the shower was pulled out from the shower wall, leaving a gap of about 1/8" or so. I caulked around that, but after seeing the damage on the floor from where the vinyl floor had peeled back, I'm wondering if the water running down the shower wall caused damage under the tub surround where I can't see. I'm looking for a recommendation if this is something I should have checked out.
