If you have a Stowaway cold-only transom showers (only has one knob) and only need the valve, why replace the whole thing? It's pretty easy to remove the shower box and replace the valve. If you need the shower wand and/or hose, we have those, too! This shower heas been used on many boats including Leopard Catamarans. Both threaded connections are 1/2" male pipe thread (actually measures about 5/8" across). Fits most standard sprayer hoses. Valve slides into 1" hole from the bottom and secures with top nut (included).
The manufacturer of this transom shower has supplied boat builders for many years and has many different models. We can get them all!
