How to Stop Toilet Tank Condensation


Just like the outside of a drink on a hot day, condensation forms when cold air hits a warm surface. This can happen to toilet tanks as well. This condensation can drip down onto the bathroom floor and cause more problems than just a slippery hazard, but a rotten floor as well.

With this being said, here are a few tips on how to stop toilet tank condensation.

  • If the problem is mostly just that your bathroom air is hot and humid, adding a dehumidifier can help dry out the air. Lowering the AC to a cooler temperature, putting fans in the bathroom or turning on bathroom vents can also help remove the excess water in the air of your bathroom.
  • Alternatively, you can purchase a fabric wrap to put around the toilet bowl that will absorb the excess condensation. These wraps are often made out of towel like fabric and are often washable as well.
  • Another option that may not raise your electric bill so much is an anti-sweat valve. This valve can be installed in the water supply line leading to the toilet. The anti-sweat valve operates by adding a small amount of hot water to the toilet bowl, raising the temperature enough to stop the condensation. These valves are relatively inexpensive and can be installed by a licensed plumber.
  • If the problem seems to be the water coming in, investing in a tempering tank that stores the water separately before it enters the toilet bowl can be a good fix. This is the most costly solution, but condensation should not be a problem once a tempering tank is installed.
