I really didn't like the original fiberglass floor in the head that served as the drain for the shower. Its curved down edges were fiberglass pressing on a gelcoat surface. Whenever any weight was put on it, it made a really loud grinding sound as it flexed (seemed to be much louder in the middle of the night for some reason).

Using the orginal fiberglass piece as a template, I put together some teak cockpit grate strips (wow, are those things expensive!), and made a new insert.

The lip around the recess was just enough to hold the new floor. The added ventilated area allows for quicker drying of the little bit of water that the sump pump never gets all the way out.

A drawback to this scheme is that I had to put a filter in-line with the drain hose before the pump, since you couldn't put in a little rubber sink trap drain like the original floor had.

This filter fit nicely right under the hatch in the sole next to the pump just outside the doorway to the head. A check valve is the next thing to put in line with this system. After the pump switch is released, there is a backwash of about 8 oz. of water that comes back into the sump recess.

This looks so much better also!
