6 Ways to Stop Your Toilet from Sweating

In certain countries and locations, people have experienced a phenomenon known as toilet sweating. Toilet sweating, or “sweating toilets”, happens when condensation and moisture build-up inside a toilet tank, causing the tank to feel damp and cold. High levels of humidity in the bathroom or poor ventilation usually cause this. If a toilet is sweating, it can cause damage to the tank and other parts of the bathroom. Toilet sweating usually occurs in summer when heat and humidity levels are higher than usual.

In this blog post, we will discuss the various problems caused due to toilet sweating and how to prevent it.

Problems caused due to toilet sweating

Toilet sweating is a common problem that can cause several issues. Let us understand what these issues are:

  1. Damage to walls and ceilings: Excessive condensation in your toilet can cause moisture to build up on surrounding walls and ceilings, leading to rot and other forms of water damage. This will lead to the high cost of repairing the whole bathroom.
  2. Mold and mildew growth: Excess moisture from sweating toilets creates the perfect conditions for mould and mildew growth, which can cause some severe health issues.
  3. Damage to surfaces: Sweaty toilets can cause discoloration and staining of surrounding surfaces, such as paint, wallpaper, and tile. It leaves your bathroom shabby and unpleasant and can be embarrassing for visitors.
  4. Slippery floors: Excess moisture on the floor around the toilet can create a dangerously slippery surface. This can result in accidental falls that can be pretty serious.
  5. Unpleasant odours: Excess moisture can lead to unpleasant odours in the bathroom. Again, an undesirable trait to have in one’s toilet, especially when having guests over.
  6. Higher water bills: If left unresolved, toilet sweating can lead to higher water bills due to the toilet running more often than necessary.


How to Stop Toilet Sweating

Now that you have understood what problems you may face in the event of having sweaty toilets let us learn how to prevent it from happening or what to do when it happens:

  1. Install a toilet tank liner: A toilet tank liner is a plastic insert that fits inside your toilet tank and helps to insulate it from cold water. This will help reduce condensation from forming on the outside of the tank.
  2. Install a toilet tank cover: Installing a toilet tank cover helps to keep the warm air inside the tank and prevent cold air from entering. The cover also prevents the toilet from sweating.
  3. Apply a sealant: Applying a waterproof adhesive to the outside of the toilet tank will help to protect it from condensation.
  4. Use a dehumidifier: A dehumidifier can help to reduce the humidity in the bathroom, which will help to reduce the amount of condensation on the toilet tank.
  5. Open a window: Opening a window in the bathroom can help reduce the room’s humidity and prevent condensation from forming.
  6. Increase air circulation: Increasing air circulation in the bathroom by running an exhaust fan or placing a fan in the room can help to reduce the humidity and prevent condensation.


Some of these are easy DIY hacks that can prevent toilets from sweating. However, for more severe cases where these tips do not work, it is best to call in a professional who can eliminate your sweaty toilet problem in an instant.


Advantages of Hiring a Plumber

Hiring a plumber to repair a sweating toilet is essential to fix the problem correctly and efficiently. A plumber can accurately identify the cause of the sweating toilet and take the necessary steps to fix it. This may include installing a new wax seal, replacing a damaged or worn flapper, or adjusting the water temperature. Getting a professional to repair the toilet also eliminates any guesswork, ensuring the job is done right the first time. A plumber will also be able to advise you on the best course of action to prevent the sweating toilet from happening again in the future.

What the Plumber Will Do

To repair a sweating toilet, a plumber will typically start by inspecting the bathroom to determine the cause of the issue. This may include checking for signs of leaks and inspecting the wax seal that prevents the toilet from sweating. If the wax seal is broken, the plumber will replace it. The plumber may also recommend installing a water-saving toilet to reduce the amount of water used and the amount of sweating. The plumber may also suggest replacing the toilet’s flapper valve or adding insulation to the tank to reduce sweating.
