Hey all you DIYers!
If you have been watching the news, you know that the new Ice Age is upon us here in Portland, OR. And since our travel plans are canceled and we have been snowed in, it's time to combat cabin fever with some of those projects that have been festering. Like this one - PO had caulked wood molding into joint where tile wall meets tub and it took about the year that we have owned the house for the caulk to mold and the wood to bow away from the tile.
My wife had enough and finally ripped it all out the other day. My question is how to fix it. I have found nice black tiles at Lowes that would work Counterparts at Lowe's: 2" x 6" Bright Black Radius Cap Ceramic Tile- They are rectangular, have a radius cap and are tall enough to overlap the existing tile. But to secure them do I need to provide some sort of backing below the tile? You see in the pics that the tile ends approx. a inch above the surface of the tub and the tub liner recedes about a 1/2" behind the tile. Do I need to fill this gap with something or should I just adhere the new tile to the tub surface, grout, and call it good?
I have included pics to better illustrate what I am talking about. If any other Pacific Northwesterners are killing time inside, please lend your expertise.
