I had misjudged the tile+thinset thickness in my bathroom and framed the tub recessed box so that the tub sticks out by about 1-1/4" from the studs. After the cement board, that is about 3/4". However, the tile I ended up choosing is glass mosaic, which is only about 1/4" thick and, because it is mosaic, it requires very little thinset to be nice and uniformly flat. That leaves me about 3/8" of tub protruding out from the tile level.
I had a meeting with my tile guys this morning and they said it wouldn't look good (as you can see the black side of the tub that is supposed to be inside the recessed box) and I agree. What they suggested is putting another cement board over it and another piece of greenboard above. The problem is, the cement board and green board are 1/2", slightly more than the 3/8" that I have, plus the other side of the tub protrudes even less than 3/8". So what I was thinking was to use some sort of epoxy/caulk to fill in the corned to make it somewhat more graceful of a transition. It still wouldn't look perfect but oh well. I would like the epoxy/caulk to be something that becomes hard as a rock (or tile) when it hardens and comes in different colors.
My question is: which epoxy/caulk should I use. Please see the illustration.
