Room package · RBL-1
Bath + Laundry
The most popular way to use one cube: a full bathroom with a washer-dryer on the same wet wall. Shower, toilet, vanity and laundry in about 80 square feet.
- Two rooms in one cube. a full bath and a laundry share one wet wall, one chase and one lift pump, so you save a cube
- Built and tested before it ships. pressure tested, flood tested and leak-sensor tested in our shop
- No dryer vent. ventless heat-pump drying, so nothing opens to the surface
- Water-safe. a leak sensor at every fixture closes the main valve automatically
- Fresh and dry. the exhaust fan and humidity sensor pull damp air and odors out through the shelter exhaust

How it is built
Built in our shop, inside the cube: wet-area walls, plumbing, wiring, fixtures and cabinets, then pressure tested, flood tested and leak tested. On site, your installer snaps the water, drain, power and air jumpers together at the cube joint and runs every fixture.
