Condensation on the outside of the toilet tank, also referred to as sweating, is a common problem that is caused by a difference in the temperature between the toilet tank and the surrounding air. This constant accumulation of water on your toilet drank can then drip onto the floor, keeping the bathroom damp and promoting mold and mildew growth. Thankfully, there are a few simple things that you can do to prevent your toilet from sweating.
While treating the symptom more than the actual disease, you can install a drip tray underneath the toilet tank to collect water that falls off of your toilet tank before it has the chance to hit the floor. This can help prevent the spread of water, even if it's just until you find the time to implement a better solution.
If the flapper of your toilet (also sometimes called the flush valve) is slightly open, it can allow water to slowly trickle out of your toilet tank into the toilet bowl, lowering the overall temperature of the tank and making condensation more likely. To check to see if this is occurring, put food coloring in the tank and wait for a few hours. If the coloring has seeped into the tank, you'll need to replace the flapper. This is a fairly inexpensive fix, and flappers can be found at most hardware stores.
If the flapper is properly in place, you may want to insulate your toilet tank. This prevents the tank from getting cold, which in turn prevents the moisture in the warmer air outside your tank from condensing. Toilet insulation kits can be found at most hardware stores, and are fairly simple to install. Simply empty the toilet tank of water, cut the insulation panels to fit onto the sides of the tank, and then apply them using the included adhesive.
Change Your Bathroom Routines
If the flapper is in place and toilet tank insulation is inadequate from preventing toilet tank condensation, you may want to consider changing your bathroom routine in order to lower the overall amount of moisture in the air. Try to take shorter showers and baths, or reduce the temperature somewhat, to prevent the air in the bathroom from becoming too warm. Additionally, leave the bathroom fan on after you take a shower to help ventilate the bathroom and remove any excess moisture.
