This stainless steel shower was a fun project. It is made from 316L stainless steel and has a mirror finish. The water travels in an enclosed pipe from the inlet on the bottom to the shower head on top. A quick connect water supply fitting is connected at the base to supply constant water then there is a shut off valve in the middle to control the flow. We used knurled thumb screws to connect the clamp from the shower to the handrail. Not only did we fabricate the shower but our plumbers made the water supply run from the engine room that included ABS approved bulkhead penetrations.
