We have decided that we are going to live in our current house for the
duration, so 'My Big Plan' is to Seniorize the house. I've just
completed all the lighting upgrades and I'm now moving on to the one of
the big ones. I will be tossing the shower/tub surround unit and
building from scratch a fully enclosed, floor to ceiling shower only,
with a low or no stepover, in the same space using the existing plumbing
layout. There is one hitch (so far). Those stock size, overpriced box
store fiberglass floor pans won't work for me. I need a custom dimension
floor.

So far its been suggested that I use a cement board underlay then trowel
out some kind of mix on top to get the slope to the drain, then tile.

Someone tried to describe a method where a waterproof membrane is put
down first... I didn't really catch what he meant.

The framing under the surround was properly built up to support the
current unit, so weight shouldn't be an issue

I'd appreciate hearing your ideas
