Atherton made the bathtub and sinks by hand, out of marine-grade plywood held together with aluminum spline joints and dyed with Behlen Solar Lux in jet black. To make them waterproof, he coated every surface in a thick layer of West System marine epoxy, popular with builders of wooden boats. The components are inexpensive, but the process is time consuming: Each piece took five days to make.
