Hi all -
I have installed an acrylic tub, but one thing about its edges has me stumped.
From what I understand, normally one would want to place something like galvanized metal flashing over the edge flange of the tub, tacked to the wall so that it hangs down over the flange, so that any water that might leak behind the tiles would not get behind the edge of the tub at the wall. The installation instructions that came with my tub show a cross section of the edge of the tub as simply coming straight up by an inch or so - which is what I expected.
However, the actual edge of the tub is not like that, and instead, is "benched", between 1/4 and 1/2 in., before turning down into the tub.
How can I place flashing over this? Should I even try? Or, should I just lap that with poly? I am worried that if I don't do anything, the little gap between the tub and the cementboard (which of course, I would silicone) may open up over time as the caulk dries, and hidden behind the tile, I wouldn't notice, and moisture would enter.
Anyone have any suggestions, or at least, experience with this kind of (acrylic) tub edging?
(Hopefully, my description was clear, if you have a similar acrylic tub (mine's an American Standard "Marina"), you'll know what I mean).
Thanks for any advice,
C.
