In a small bathroom, we removed the tub to install a curbless shower. Chip some tile out, remove the drywall to take the rest of it, and put up plywood and tilebacker in preparation for the solid surface panels, which we arbitrarily decided were going to be about 86 inches tall.

The room is five feet wide, and with the vanity taking up half the length. Just before I cut the plywood B— called and asked, “how big is the bathroom doorway?”

It's only big enough for a panel 82” tall.
