I am in the process of replacing the wall surround above and all the way around an existing fiberglass (or some sort of plastic) tub. The original surround was 4" tile over greenboard and (according to the inspector when we bought the house) the window sill in the shower area leaked water because it was tiled and not a solid marble sill.
The greenboard is gone, I have placed concrete backerboard on the back and the long side of the tub. The tub has about a 1/2 - 3/4 in "ridge" on the three wall sides that the backer board is resting on. The backerboard is screwed into the studs with the mfg.recommended screws. The next step is the thinset and taping.
OK, so here is the question: Do I fill the gap between the bottom of the backer board and the tub surface with thinset, tub caulk, or what, again its about a 1/2" high by 3/8" deep area to fill.
Finally, once filled, I will be using large (either 8x12 or 12x12) tiles. should these be set all the way down to the tub surface level or should there be a gap for caulk or ????
Thanks for any help you can provide.
