Great to know! I'm think the best solution is a straw-filled seat wrapped with something waterproof that can be cleaned and then maybe put tinfoil around that.
I would still like to be able to create a quick space heater kind of thing. I found that a candle in a regular rocket mass heater that was half built (no mass yet) threw off a surprising amount of heat, and if you touched the barrel that would definitely warm your hands up quick on a cold day. So a superquick space heater with a candle. . .
Electricity and bathrooms don't mix well, for safety.

One that I will admit works great, if not the most permie due to the material, is a styrofoam toilet seat. I have one on my composting toilet and it is ridiculously cozy in winter! It radiates the warmth from your body back at you. It is a little hard to clean. But maybe it's an idea to explore, perhaps there's another material that could work similarly?
Or you could fashion some kind of fabric cover for the toilet seat. Though I imagine if you did something like that, you'd need to wash the covering somewhat frequently. Maybe make a few so you could rotate them when cleaning became necessary?
