Why is my Toilet Sweating?

Why is my Toilet Sweating?

A sweating toilet may not concern you; however, it can lead to damage of your flooring, sub-floor, mold and mildew, create a safety hazard, and more.

As the weather heats up, the only thing that should be sweating is you, not your toilet. If you are wondering, “Why is my toilet sweating?” you are not alone. Every summer, millions of homeowners have to deal with toilets that perspire puddles of water onto the floor. What makes this happen? Let’s review.

Why is my Toilet Sweating?

Water that enters a toilet tank is relatively cold, around 50° to 60°F. This makes your toilet cooler than the air that is around it. When warm, damp air hits a cold surface, condensation forms. This is due to the difference between the cool water and the warm, humid air, outside.

As the temperatures outside and inside of our homes rise beyond the temperature of the toilet, and more humidity is in the air, when the warm moist air hits the cool porcelain toilet surfaces, the air condenses, turns to water, and starts to drip, causing your toilet to sweat.

How Can I Prevent my Toilet from Sweating?

A sweating toilet may not concern you; however, it can lead to damage of your flooring, sub-floor, mold and mildew, create a safety hazard, and more. There are things you can do to prevent your toilet from sweating. Let’s review.

Reduce Humidity and Moisture in Your Bathroom: If your bathroom has low humidity, your toilet will not end up with condensation. Consider taking shorter and cooler showers, always turn the vent/fan on or open a window if you don’t have one, keep the door open, and/or use a dehumidifier in the space. Wipe down walls and glass after you shower to eliminate the excess moisture.

Don’t Open Windows on Hot and Humid Days: While it’s a good idea, if you don’t have vent, to open a bathroom window while showering, it is a bad idea to open windows to let the heat and humidity in, any other time. If it is warmer outside than inside, and especially if it’s both warmer and more humid outside, keep the windows closed.

Add an Anti-Sweat Valve to Your Toilet: An anti-sweat valve adds a little hot water to the toilet water line, which raises the water temperature in the toilet enough to warm up the tank and bowl. By installing this valve, you can prevent the condensation from forming, as the water in the tank is not so cold.

Invest in a New Toilet: Many modern toilets have insulated tanks and are low-flow, meaning they store less water. Both of these things should prevent sweating. If you have an older toilet it may be time to replace yours with one that has some of the modern features that are designed to stop toilet sweating.

Visually Address the Issue: While these options can go against your style and décor, think about adding fabric to your toilet to absorb the moisture or a toilet tray to catch it. Neither of these options will stop the toilet from sweating, but they keep the condensation from causing other issues for you.
