As an experienced plumber, I’ve encountered many cases of toilet sweating, and I understand the frustration it can cause. I’ll share eight proven ways to stop a toilet from sweating in this guide.
These solutions will help you tackle the issue effectively, from simple insulation techniques to humidity control methods. I’ve got you covered whether you’re dealing with sweating in the summer or winter.
Prepare to say goodbye to those pesky droplets on your toilet tank and create a more comfortable bathroom environment. Let’s dive in and solve your toilet sweating problem once and for all.
How Do You Know Is Your Toilet Sweating Or Leaking?
Distinguishing between a sweating toilet and a leaking toilet can be determined by observing the source of the water.
If the water is on the outside of the tank or bowl, it is likely sweating due to condensation caused by temperature differences. Water pooling around the toilet’s base or coming from the tank or supply line connections indicates a leak.
Checking for consistent water presence, inspecting connections, and identifying the exact location of the water will help differentiate between sweating and leaking issues.

Why Does My Toilet Keep Sweating?
A toilet can sweat due to condensation, which occurs when the water temperature inside the tank is colder than the ambient air in the bathroom.
When warm, humid air comes into contact with the cold surface of the toilet tank, moisture in the air condenses, causing droplets to form on the outside of the tank.
Several factors can contribute to toilet sweating:
1. High Humidity:
Excessive moisture in the bathroom can exacerbate condensation on the toilet tank.
2. Temperature Differences
Significant temperature variations between the water in the tank and the surrounding air can lead to increased sweating.
3. Inadequate Insulation
If the toilet tank is not adequately insulated, it can be more prone to sweating.

Is It Bad For A Toilet Tank To Sweat?
While toilet tank sweating itself is not harmful to the tank, it can cause some issues if left unaddressed:
1. Water Damage
The excess moisture from sweating can damage the surrounding area, including the floor, walls, and nearby fixtures. Over time, this can lead to discoloration, mold growth, and even structural damage.
2. Slippery Floors
The water drips from a sweating toilet tank can make the bathroom floor slippery, posing a potential safety hazard.
3. Increased Humidity
Persistent sweating may contribute to higher humidity levels in the bathroom, promoting mold and mildew growth, leading to potential health issues and unpleasant odors.
While sweating is not detrimental to the toilet tank, it is advisable to address the issue to prevent any associated problems.
Taking steps to reduce condensation, such as insulating the tank, improving ventilation, and controlling humidity levels, can help mitigate these concerns and protect your bathroom from water damage and related issues.

8 Ways To Fix A Sweating Toilet
Have you ever noticed water droplets forming outside your toilet tank? This phenomenon is called sweating, a common occurrence in many homes.
Not only is it unsightly, but it can also be a breeding ground for bacteria and mold.
Luckily, there are a few simple solutions to fix a sweating toilet that won’t cost you a fortune.
Here I have rounded up eight tried and tested ways to stop the drips and get your toilet back to its dry self again.
1. Adjust The Temperature In Your Bathroom
Sweating toilet tanks are often caused by the difference in temperature between the cold water inside the tank and the warm, humid air in your bathroom.
To fix this, try turning down the temperature in your bathroom. Not only will this help reduce sweating, but it will also save you money on your energy bills.
2. Use Insulation
Another way to fix a sweating toilet is by adding insulation to the tank. You can purchase insulation kits made explicitly for this purpose at your local home improvement store.
Wrap the insulation around the outside of the tank, and you’ll help prevent the temperature difference that causes sweating.
3. Install A Tank Liner
For a more permanent solution, consider installing a tank liner. This thick foam rubber liner will help insulate the tank and prevent sweating. Plus, it will also help reduce the sound of water flushing.
4. Replace Your Tank Lid
If your tank lid is cracked or damaged, it could contribute to sweating. Replacing it with a new, well-fitting lid can help reduce moisture buildup.
5. Check Your Water Pressure
High water pressure can contribute to sweating toilets. Consider installing a pressure-reducing valve on your water supply line to fix this.
This will help regulate the water pressure going into your toilet tank and reduce the amount of sweating.
6. Install A Ventilation Fan
If your bathroom has no ventilation fan, consider installing one. This will help reduce the humidity in the air and prevent sweating.
7. Use A Dehumidifier
If your bathroom is particularly humid, consider using a dehumidifier to remove excess moisture from the air.
8. Call A Plumber
If none of these solutions work, it might be time to call a professional plumber. A plumber can assess the situation and determine if any underlying issues are causing the sweating.
They can also recommend a more permanent solution to fix the problem.

How Do You Install An Anti Sweat Valve?
Installing an anti-sweat, mixing, or tempering valve can help reduce toilet tank sweating. Here’s a general guide for installation:
Step 1: Shut Off The Water Supply
Turn off the water supply to the toilet by closing the shut-off valve on the water supply line.
Step 2: Drain The Tank
Flush the toilet to drain the water from the tank completely.
Step 3: Locate The Hot And Cold Water Supply Lines
Identify the hot and cold water supply lines connected to the toilet tank. The hot water line typically connects to the left side of the tank, while the cold water line connects to the right side.
Step 4: Install The Anti-Sweat Valve
Choose an appropriate location for the anti-sweat valve along the hot water supply line.
Cut the hot water line and install the valve according to the manufacturer’s instructions, typically using compression fittings or soldering.
Step 5: Connect The Hot Water Line
Connect the cut ends of the hot water supply line to the inlet and outlet ports of the anti-sweat valve using the appropriate fittings.
Step 6: Turn On The Water Supply
Slowly turn on the water supply at the shut-off valve, allowing the tank to fill. Check for any leaks around the newly installed valve and fittings.
Step 7: Adjust The Valve
Once the water is flowing, adjust the anti-sweat valve to regulate the temperature of the water entering the toilet tank.
Follow the instructions provided with the specific valve model for adjusting the temperature.
It’s important to note that the exact installation process may vary depending on the specific anti-sweat valve model and the manufacturer’s instructions.
If you’re unsure or uncomfortable with the installation process, it’s recommended to consult a professional plumber for assistance.
