feedback bathroom reno

I am a novice builder working on a 2nd floor bathroom renovation.I have gutted the room completely down to studs and floor joists.I took out a wall and incorporated the space from a closet in an adjoining bedroom.I moved the toilet to the opposite wall so I could install a larger vanity (48inch as opposed to 30 inch).I have installed new wiring circuits for the pump and heater on a whirlpool tub.I have installed recessed lightling and moved the existing light fixture to be centered on the new vanity, and have installed a new GFI socket for hairdryer.I have also modified the tub/shower fixtures to accomodate the larger tub and have modified the plumbing for the new vanity.I have layed a new subfloor(5/8 plus 3/4 plywood.)

My next steps are to install new drywall and build a tub deck and I am stuck on how I should proceed.

Should I build the tub deck first and incorporate its framing into the framing of the room, or should I drywall first and build the deck after?

I plan on useing Kerdi waterproofing around the tub. Should I use drywall or cement backer board to support the tiles on the walls?

The weight of the tub is to be supported by the floor and not the tub deck.At the same time I want a close fit between the tub and the tub deck so I can waterproof the joint.By the time I add cement board,Kerdi liner, mortar, and tile to the top of the tub deck, I don't know how thick this will all be.Its hard for me to accurately build the framing for the tub deck.Maybe I can build it slightly higher and use extra mortar to build it up to the tub edge? I dont know.How would a pro get this measurement right.

Thanks for your help.

Just thinking logically, I would put the tub in place, fill with water and add all the heavy peripherals and frame to suit the position. But others with more direct experience may have better ideas. HTH

Your choice. Either way will work fine.

cement backer board

Build it slightly higher. Pour a bucket of mortar onto the floor, set the tub in place and press it into the mortar.
