I work on a boat, and we're in the shipyard getting our 3 year overhaul. I'm in the parking lot working on the box truck lol.
Here is the shower framed up and mortar bed in to make everything slope towards the drain. There is maybe 1/4" of mortar in half of a 9 sq ft shower.
Insulated, walls are Kerdi Board foam backer board. Shower pan is Oatey shower pan system.
Tile grout drying:
BOOM!
Walls are FRP. I am going to trim every corner with aluminum. Everything is waterproof even before the FRP is up, but I am going to silicone the crap out the trim.
And still some FRP to install.
