morter bed?

I have sistered a couple od floor joists in the bath room. Still have about 3/4" drop in 5" where the new tub will sit. This tub has a support grid on the bottom. Would a morter bed sized to fit the built-in tub support be okay to provide a level surface for the tub? Sub flooring is 3/4' 1X6 on diagonal. Morter bed for tub support, tapered shim for outside edge? Then 3/4" underlayment for area outside of the tub? I realize this will leave a 3/4" diff in exposure of tube at the rear of it. The built in tub support grid is some kind of hard plastic/fiberglass.

Sounds ok to me. I would imbedd some "chicken wire" in the morter bed, and be sure to lay down a couple of layers of #30 felt betweeen the diagonal flooring and the morter. Probably overkill, but I personally would come back the next day and use thinset to bed a layer of tile backer board to the top of the morter bed, to provide a real nice surface for the suport grid.

morter bed?

Is this tub fiberglass/acrylic or cast iron? Americast?

If you have to level the floor under the tub, don't you need to level the whole room for your finished floor? If you're sistering, why not cut out the whole room's subfloor and level the whole room?

Fiberglass. I tried the shimming and was not satidfied. Went ahead and cut most of the subflooring out and sistered every joist to level it up. Directions say to use latex/acrylic on the surround. Anything wrong with using a silicone product?
