I have a nice drop-in fiberglass jacuzzi tub with all the goodies, I want to put in place of a regular tub. I'm pretty determined, and have a few thoughts, but would appreciate the insight of the group. I plan to notch the walls to accept the edge of the tub, then put the drywall (or backer board up). I'll need electricity, so the wall at the head of the tub will be totally stripped and reworked and an access panel left (Fortunately that wall is just a room divider backing on to the sink area.) My main concern is the area where the deck meets the wall, normally a tub has an "L" there to keep the water from seeping behind, with this being designed as a drop in it doesn't. I thought about bonding aluminum angle to the edge & while perhaps unsightly & overkill, that would probably work. This is where the community might know a lot more than I do.
It looks like this:
