Denray Posted December 18, 2009 Report Share Posted December 18, 2009 A couple of weeks after getting out of HI school 10-05 my wife says "What's this black stuff on the floor of our towel closet"? The wall just opposite the shower fixtures.

After all I was uncle Buck on the tile installation. The grout was easy to clean. Looked good. The shaving mirror above the tub corner dripped hot water down on top of the horizontal corner surface of the tub.

The fly in termites had a health spa going on. With the dry wall removed you can see little white vertical stripes all along the tub rim where water was being sucked over elsewhere as well.

Jim Baird Posted December 18, 2009 Report Share Posted December 18, 2009 Tile on top of drywall isn't the best way to go either. My tile installation had thin joints, due to cheapness of tile, and cracks there led to my having to remove a cpl of courses and redo. I used hardiboard instead.

Yes. And replacing it with silly-cone isn't a solution. If I were inspecting that house, I'd be recommending ripping out the tile surround and starting over. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Denray Posted December 19, 2009 Author Report Share Posted December 19, 2009 I've seen grout at the tub a few times on some home inspections. And I know it can be bad. The studs showed no water damage. The dry wall was ok other than the stains creeping up the bottom 2 inches. The grout between the tiles has not cracked. I'm sure I will be doing it the right way as soon as it starts to fail. I look up every once in a while thru the P-trap access in the sub floor and all looks dry. I was ignant when I ok'd it being installed that way. We had the house built and I did a lot of finish work on it during my ignant days.[:-paperba Quote Link to comment Share on other sites More sharing options...
