Any suggestions to help with a sweaty toilet?

An old trick I was told about, in some very moist areas, is to hook the feed water from the hot water not the cold.

Here are what seem to be your options. I’d try the fan in the bathroom first.

As a side note, I had a friend that was having this problem once. It finally turned out that the cold water in the toilet tank cracked the tank, and it was a hell of a mess. I remember going to Re-store (Habitat’s store) with him because it was one of those ranch ‘baby blue’ bathrooms and he was looking for a blue water tank. They said the blue and pink fixtures were the first to sell.

Here’s one with a coaster link.

Drain the tank, clean and dry completely, then glue thin sections of Styrofoam to the inside of the tank. Or replace the toilet with a model that has an insulated tank. There are also proportional valves that feed a mix of hot and cold water to the tank. (See your plumber.) Or do as Tropical_Willie suggests.

If you live in an apartment, you probably don’t want to spend a lot of money replacing things that should be covered. You could ask the landlord to take a look and see what he suggests (and then he’d be paying).

Yeah, we are in a apartment. The landlord has been contacted a few times but doesn’t seem to care. Which is kinda fucked up since we are on the second story and I am fairly sure there is substantial water damage to the sub-floor. I’m just waiting for the toilet to crash into our neighbors below.

I asked a friend who does HVAC and plumbing, and he seconded the idea about lining the inside of the tank with styrofoam. Probably minimal expense, as you ‘d drain, dry and use styrofoam with probably some kind of glue, which should only be a few bucks. I wonder if the styrofoam could be the stuff they pack items with (comes in thin sheets)?
