I'm about to install a drop-in Jacuzzi acrylic soaking tub. It has 6 support pads on the bottom, but my plan was to support the tub using just the outer 4 pads to make it easier to level. The support will be by two 2" x 6" x 34" laminated oak boards that I can plane down to whatever final thickness I want. The boards will rest on the 3/4" underlayment, span two floor joists, and end a few inches short of the outer wall support structure. My question is that in deciding on a final support thickness, how much of a gap should I leave from the outer flange to the granite surround? My guess was to leave about a 1/8" gap and use a 100% silicone caulk to seal it up.
