Ok, the bathtub won't come out, I'd have to take down a wall.
Can't do a compolete remodel. We wanted a new tub.
Just going to replace the one wall with the window, I didn't
want to use the cement board, heavy, awarkward and as you
can see from the picture it doesn't hold up well.
Was thinking about using insulation board, I love it and it's
so easy to work with. Might be a little weak if someone fell
into it so wasn't sure. Don't want to forget it though.
Found two new materials on youtube:
LINK How to Waterproof a Shower (3 Awesome Methods!!)
-- by Home Repair Tutor
Writing it now 'cause I'm going to bed and don't want to forget.
Kerdi board
Wedi buildint panel
Both lighter and easier to work with.
I'll check Home Depot after I get up.
