Or, if you are from Wisconsin, "The Doggie Bubbler"
1/5th size steam-table pan
Faucet from the clearance shelf at Menard's
Too many plumbing fittings and attachments from the hardware stores (multiple trips req'd, of course)
A solenoid valve from eBay
90 degree through-hull fitting (adapted to use as the overflow)
Leftover pre-finished cabinet plywood
Of course, I still have unpainted window trim in this place; but this sure is cool!
