Work has been under way on the tiled bathroom and a few other interior issues. The bathroom area is a simple european styled shower/toilet/sink layout with a shallow curbless shower pan integral to the tiled floor. The two adjacent shower walls are to be tiled to the ceiling, with the other wall behind the toilet and sink tiled to 4', with mirror and shelving above.
The bathroom finish out began with bumping up the floor sheathing thickness with plywood and backer board to allow for the required 1/4" per foot slope to the drain in the 3'x 6' shower pan; in our case an additional 1 1/8" above the subfloor. We then built out a sloped dry-packed mud shower base, over which we applied a continuous waterproofing membrane by Noble, NobleSeal TS. This provides a thin waterproof substrate overwhich we can directly apply thinset mortar and the 2x2 ceramic tile.
Once the shower pan liner is installed the 15# tar paper moisture barrier is installed prior to the application of the Hardi-Backer, over which will be installed the 3x6 subway tile.
On the short wing wall between the kitchenette and the bathroom was installed a plywood pantry shelf. A 3/4" birch plywood box with a red-lacquered back, finished with Watco Danish Oil, fit within the stud bay. The 6' tall by 6" deep pantry has one fixed shelf and a series of peg-holes for moveable shelves above. This tiny but incredibly useful pantry will serve the kitchenette with easily accessible storage.
The mini-split AC unit was also finalized and hooked up to the exterior condenser. It should provide ample cooling and heat for the 180 s.f. interior space.
