We have a 5' x 5' walk-in shower in our new house we're building.
We're not putting a unit in there, as it's not a standard unit
dimension. Ideally we'd like ceramic tile, but now we're trying to cut
corners, and we're wondering if there might be in inexpensive solution
for wall material and floor base that would make a nice walk-in shower
for a few years until we get around to an upgrade. Any advise?
