Here are the mods that I made to my wet bay (2007 Dutch Star), including the shower conversion:
1. Install Sanicon
2. Move deck plate to allow easier pass-thru for sanicon head
3. Install horizontal hose reel
4. Install adjustable in-line water pressure regulator
5. Install winterizing bypass system for filter
a. Of course, after that, I installed a water filter with built-in bypass
6. Install utility faucet (with hose threading) to replace shower.
a. Can connect hose for black tank wash down
b. Can connect hose for warm-water dog washing
7. Install paper towel dispenser (w/ fly-away preventer)
8. Install holder for nitrile glove box
9. Install in-bay tank monitoring and pump switch
10. Use remote temperature sensor for in-cabin weather station to monitor bay temp in cold weather
11. Since this photo:
a. Replace blue filter canister with clear canister
b. Removed winterizing tube (I winterize with air & the tube was pretty disgusting)
Okay, a little OCD!!!
