Villa, you caught me I was mostly being an humorous but after going to Japan they REALLY love their toilet seats, even the one Neal shows pails in comparison to what I saw over there. though I only want a wooden seat with a durable finish.
I thought acrylic really wasn't good for moist areas but that one is interesting, at $320/Gal ($100/quart) it's also one of the most expensive things I've ever considered... I'm not much of a spray paint kinda guy so I'm not sure how I feel about that... and since I'd be sitting on it I think I'd rather have it really smooth than textured. Also if I were a werewolf I would steer clear of this silver stuff unless I wanted to encourage short visits to the bathroom!
The lid was the first thing to snap but the part you sit on will also be made as well since it's about to crack in half. My child (~80 pounds) stood on the lid and it crack also damaging the seat. I actually have access to all of that equipment BUT my wife wants it to match the new baseboards, framing, coat racks, chairs and everything else I've built so... I don't think metal will meet her requirement, even if it was heated....
The reason I was thinking heated is because in ND water comes in at 34 degrees a good part of the year so when the toilet fills it gets cold, and so does the seat with 4 people using 1 upstairs toilet....
Myth busters disproved it as bunk and I have also dis proven. As even a garden hose wasn't enough to conduct a significant amount of electrical current. Air is an Excellent insulator so even one minor break in the stream and the current will go down to pico/femto Amps. NOW where I did see a problem was if my son was peeing and he was only elevated a few inches above the seat and there was a short.... and soak through the wood to get to the coil.... ya very unlikey but if ti happened... I imagine it'd only happen once
