I am going to install a new corner bathtub and have a question about the edge detail.
Do I place the edge the tub on the wood frame or do I use cement board under the edge, or do I tile it too prior to putting the tub in place?
Looks like the directions say to frame then place the tub – follow up with cement board for the tile placed up to the edge of the tub then tile on top of that. The whole thing is caulked then.
Thanks –
Signed,
Not wanting to do over.

Is this a fiberglass tub or something else, and does it have a flange for wall mount, or, are all the sides turned over for a deck mount.
It is a fiberglass tub that is a deck mount.
I have made a fiberglass flange, on my shop table on waxed paper, and applied it to the sides of a deck-mount tub that go under the rock board.

Let me rephrase the question -
Should the stack be frame then tub lip or should it be frame backer board then tub lip or should it be frame backer board tile then tub lip?
For a deck mount tub in a deck mount application, (no walls runing down to the top of the tub edge @ the back.) frame, cement board, tub, bead of silicone, tile over, second silicone seal. If this is pushed back to the corner walls; 1"x 4" ledger to support tub rim. A 2"x 4" will often hit the back of the piping or air inlets. Install the tub, cement board down to tub rim, silicone joint, tile, silicone again. Some manufacturers have an add on tile flange for more $ to fit behind the cement board & on top of the tub rim, but it pushes the board out of plane. Make sure the tub is bedded in mortar. Every one of these things I have pulled out for a failure of the fiberglass tub floor was installed with no mortar, or drywall compound, under it.
<<Make sure the tub is bedded in mortar.>>
Bedding is absolutely essential to a proper installation, but....I suggest laying down a sheet of 4-mil poly on the sub-floor 1st, then put down the pile of "mud", I don't like mortar, I use Diamond brand veneer plaster mix, or, a setting type compound could be substituted, but not regular joint compound. I then lay a sheet of 1-mil poly, like a painters drop-cloth over the "mud" pile,then set your tub, that way you can still remove the tub for what-ever reason, without the "glob" stuck to the sub-floor or the bottom of the tub.
