How to Keep Your Toilet from Sweating

What is Toilet Sweat?

When the summer weather turns humid and moisture accumulates in the air, it is common for toilets to sweat – forming puddles of water on the bathroom floor. This results from warm moist air entering the cold porcelain toilet tank and creating condensation.

Sweating can have many negative consequences and can lead to:

  • Water seeping into the subfloor
  • Rotted plywood
  • Soaked floor joists
  • Stained baseboard molding
  • Soggy drywall
  • Discolored wall paint
  • Mold and mildew

The Benefits of Drying Out Your Bathroom

Toilets only sweat when the weather is hot and humid. That said, a surprising amount of water can perspire quickly – causing serious problems. For this reason, it is critical to find a long-term cure for sweaty toilets.

There are a few surefire methods to prevent your toilet from sweating. First and foremost, you want to do everything you can to eliminate water and humidity from your bathroom. There are many ways to accomplish this goal. Many methods require nothing more than paying extra attention to the humidity levels in your bathroom.

Here are our top recommendations:

  • Run an air conditioner or dehumidifier regularly during summer
  • Take short, colder showers 
  • Install and run an exhaust fan – especially while showering
  • Dry the shower walls with towels after you wash
  • Keep the bathroom door open when you shower
  • Install a portable or whole-house dehumidifier
  • Keep the bathroom window closed if it’s humid and your window open if it’s dry outside

It is also wise to check the flapper valve at the bottom of the toilet tank. When this valve leaks, the toilet will constantly replenish itself with fresh cold water. This will waste water and prevent the tank from reaching room temperature.

How To Insulate Your Toilet & Keep it Warm

One way to effectively prevent water from condensing and sweating is keeping the toilet warm. There are a few ways to warm a toilet:

  • You can line it with insulation
  • You can wrap the tank with a tank cover
  • You can install a low-flow toilet
  • You can install a low-profile toilet (because hot air rises, the closer the tank is to the floor, the cooler the air around it will be)

Two newer, state-of-the-art solutions can significantly cut down on toilet perspiration. They involve installing:

  1. An anti-sweat valve – An anti-sweat valve can work wonders. It works by mixing warm water with cold water as tank refills. This keeps the toilet water close to the air temperature – preventing it from sweating. The warm water also naturally warms up the tank and bowl, doubling its effectiveness.
  2. A tankless toilet – Also known as electric toilets, tankless systems rely on an electric pump to flush and refill the toilet. Tankless toilets are cutting edge but a slightly pricier option than traditional toilets. That said, electric toilets can significantly reduce toilet perspiration.
