How do you keep a toilet tank from "sweating" - what do you do about it?

you can try lining the inside of the tank with styrofoam.

The way to "solve" the issue for good is to buy a new toilet. You need a lined toilet. It has styrofoam(or something like it) to prevent the condensation made by the cold water and porcelain interacting with the warm air in your home. There are pans that are made to fit under your toilet for the purpose of catching that water. Not as pretty, but a cheap, temporary solution. New toilet are fairly cheap nowadays though..

You can get a vaulve that will alow some hot water to go into tank and mix with cold will cure sweating problems. will require some replumbing. if you check you might be able to get an inline warmer so that can just add it to your cold water line and just heat the water as it inters the tank. check with home depot or lowes, truevaule or someplace like that. there are cures for sweating toilet tanks.

toilet manufacturer's make toilets with insulated tanks check with Kohler , american standard , and others

check with your local plumber supply house, tell them your problem, they will suggest you install a hot water make up valve to the toilet water supply.what this will do it will mix a small amount of hot water to the cold water filling the tank.this is the only way to eliminate the whole problem.and that is cold water entering a warm tank causing condisation on the out side of the tankcovering the tank with atoilet tank cover is not good.the cover gets wet and then you have a mold promlem to deal with.the energy used is 1/2 that of a 60w lihgt bulb left on for 30 days!! your talkin penneys

In the mornings when I give my bathroom its little cleaning, I make sure to wipe the tank too. I've noticed that my toilet doesn't sweat much: Perhaps having the surfaces too clean for water to collect has something to do with it. Good luck!

You've already answered your question. As in,since theirs nothing you can do about it, deal with it. I feel this only happens when my bathroom is hot anyway, so either stop taking long showers or bring in the ac.

i have same problem when u find a good answers let me know

The cause of the problem is fact that on occasions, the temperature of the water in the tank is below the dew point of the air in the bath room and causes it to sweat. It is the same event that you have in the summer time when you have a glass of ice tea or a cold soda can and it sweats. Several people have suggested buying a new toilet with an insulated tank. That is one sure and easy way to solve the problem. but it does cost. Others have suggested lining the inside of the tank with insulation. It is also a good solution if you can get the insulation stuck directly and completely to the inside surface of the tank. That can be a real problem. You can also try a cloth cover that will covers the outside of the tank any possibly provides sufficient insulation to solve the problem. If you are tight on money, this is a good idea to try. Reducing the humidity in the room by venting is worth a try but may not be a complete solution depending of the humidity level in the rest of your home. Putting a dehumidifier in the room could also be a solution but not a cheap one. I don't think trying to heat the toilet wate is a practical or cost effective way to solve your problem. In the long run, a new insulated toilet would be cheaper.
