I forgot to mention that on my 37+ the "drain pan" is fully covered by a teak floor grate. So you never actually see the hose or the suction pickup/strainer/check valve. There is a small recess in the pan where the pickup goes. If I don't pump then the pan will hold about 2 gallons before the water comes above the teak grate. The hole that the suction hose goes through acts kinda like a high level overflow to the bildge so water doesn't spill into the rest of the head.
Similar to Ken's suggestion you might find a bildge suction that would fit. If needed you could add one of those inline check valves just after the pickup. I put a trigger sprayer similar to a sink sprayer on the showerhead so that I can really cut down on the water usage. Now I have to be careful not to forget to shut off the water when I'm done.
