water in cabin bilge

[Gary Four Winns]

I have a 2007 Vista 258, I am getting water build up in the shower bilge area in the floor of the cabin in front of the fridge. Not in the shower bilge itself but in the compartment that is holding the shower bilge kit. All the drain hoses on the box are good. I vacuum it out than typcally after a heavy rain storm I get water in there. There is no drain from that compartment to the engine bilge so the water just sits there... HELP

No idea how your boat was built so I'll mention only how mine was.
My Formula has a AC drip the empty's into the area in, under and around the shower bilge. Under the shower bilge is a hose and brass fitting that is connected to a vacuum pump in the engine room. The float for the area is behind the AC unit

I’m a little unclear on specifics around what set up you actually have.
Is the pump in the place you mention, definitely the shower pump ? Not just a forward bilge pump ?
Is there drain channels that normally allow draining aft, that are blocked up ?
Back to the shower pump set up. Is there a pump in the shower room drain or just a float switch that activates a pump in a collection area that’s fed from the shower drain ?

I know on some boats the fwd area sits a tad lower at anchor than the aft. Usually have a bilge pump in there. But keeping the water from coming in first is to find where it’s coming from. There should be telltale water lines where it dribbles in.

A shower bilge has the same enemy as your shower drain at home: hair.
The shower bilges I know have their own pump/float, and lift the waste up and overboard ... unless prohibited. If so, it goes into the poop tank. Hair can foul up the system.
If you're have sitting water after a heavy rain you have a topside leak somewhere. A band aid would be to install a second float bilge pump in that compartment, with a back flow check. Dump this into the shower box, or tee it into the shower bilge pump's hose.
