Why Does My Toilet Sweat?

21807670_sNow that we’re are in the month of April, it is time to expect the all too familiar “April shower” and all of the moisture that goes along with them. While you are probably accustom to the extra water outside, you don’t want extra moisture inside – especially not in the bathroom.

When someone in your household takes a shower, the air in the bathroom gets warm and damp. That air then hits the cold surface of the toilet or countertops and causes condensation. Condensation on the toilet is especially problematic because the water will drip down the toilet tank and onto the floor, causing rotting of the linoleum, sub-floor, and framing.

If you have noticed that your toilet tends to “sweat” frequently, here are some recommended solutions:

Toilet tank tray. Before you set a cold drink down on a wooden table, you likely place a coaster down first. A similar thing can be done for your sweaty toilet tank. A drip tray can be placed under your toilet tank to catch the dripping water so it doesn’t fall on the floor. While this is an easy and inexpensive fix, you will need to deal with emptying the tray periodically.

Change behavior. You and the other members of your household can work together to reduce the chances of humidity in the bathroom. You can take showers at a lower temperature and duration. Always use the bathroom fan, leave the door open, or crack a window.

Check your toilet. If the flapper in your toilet tank is not securely sealing, the tank will be continuously refilling itself with cold water, making the tank constantly cold. This cold tank is more likely to accumulate condensation. Make sure that your toilet flapper is fully sealing after each flush to prevent the tank from being cool all the time.

Tank Insulation. You can visit a home improvement store and purchase a toilet tank insulation kit. These kits are designed to insulate the inside of the toilet tank, and can be difficult to install.

Minimizing the moisture in your bathroom is important for many reasons. Water damage can be expensive to fix, and can attract mold and mildew to grow. If you have a sweaty toilet, try some of these recommendations to help fix it.
