Epoxy/caulk to smoothen corner where bathtub stick out from tiles 3/8"
 
1 Attachment(s)
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.

I know this isn't the answer you're looking for, but if it was me, I would probably just cut a piece of shoe molding to fit your 3/8" offset and paint it whatever color you want.

You can get some of the composite board that is 3/8" maybe even 1/4" thick. Not knowing if you are tiling over the green board too, if you are, and it is just a flat wall section, the same thin material could go over the green board.

I am really looking for some kind of super hard epoxy

fetzer85 03-26-2013 02:09 PM

In that case pretty much any epoxy you choose is going to be super hard. I haven't used any for a long time but from what I recall most, if not all of them, are paintable so I wouldn't over think it.

Have you tile the wall yet?
If not then the board needs to come down and shim the studs out to do it right.
That areas going to move slightly and crack anything hard you try to apply.

that is way more than am i willing to do at this point. if it cracks then maybe i should just use some rubbery caulk and call it a compromise.

I think I would have that wall you have there come out a full tile beyond the tub, but its hard to tell what you are working with there. A photo would be nice.

As many pictures as I've seen on this and any DIY site where the wall and floor are now all shot becuse of not having the tiles come out far enough and the ones I've seen in person I totaly agree.

I agree with Joe and Jagans. If you are planning to keep this bathroom for a long time, take the time and fix it or you'll be fixing that "caulk" for a long time on a regular basis.

Duckweather 03-26-2013 05:02 PM

I figured that idea wouldn't fly Joe, jagans, guess I should have said it, but thanks for doing it.

I bet if I put a fat bead of Quad window sealant, it would look alright
