Fitting wet room tray in to corner -- tanking to surrounding two walls?

[davemul]

Hey guys

I'm completely gutting our bathroom (walls/ceiling and floor)

I'm putting up 12.5mm marmox board on all the walls and fitting a 900x900 showerstone tray in the corner direct to joists, surrounded by 18mm ply and 4mm marmox board.

My question for today is...

A) Do I fit the wall boards first to the studs, all the way down to the joists..THEN butt the showerstone tray up to these boards.. and tank the joins with waterproof tape?

or

B) Do I fit the tray in to the corner then fit the wall boards so the come down on to the tray, and then tape the joins?

thanks guys

B it is then gents, thank you!

I will use marmox sealant when joining the boards to each other on the wall studs and screwing. Also taping the joins. I will also probably paint the wet room areas walls with mapei mapegum.

Can I use the mapegum on the floor too? or would I be better off using a waterproof membrane? (will tape and seal joints as per walls also)

thanks

Dave
