Okay, we moved in our house and we bought a new $80 toliet seat cover... it was $80 because it was the only color my wife liked.... well it broke. SO we've looked for almost a year and can't find a similiar dark color, SO I'm making one. I'm about ready to start but then I come up with a ton of questions! I love poly, I mean REALLY love the stuff, it's my best friend, BUT is Poly the right sealer for a toilet seat? Looking online would a spar varnish be better? I had just planned to use Oak so it matches all the other wood I've built & stained in the house but, any reasons why another would be better (tried to talk my wife into cedar hehe). I'm also thinking (not very hard) about putting a ceramic coil in the seat as a seat warmer maybe 50W so when the light comes on the seat starts to warm up, as well as install some stepper motors and a gear drive to automate the toilet seat moving up/down. (ignore dangers of heater near water I can handle that part as I've got a plan to virtually hermetically seal it and I've tried peeing on an electric fence it doesn't work). If I go the electric route, maybe I aught to put a UV light in the cover as well so it kills the bacteria on the toilet seat. But ignoring the electric stuff the main question is about the wood/sealer that would be optimal for this application.
