Written by Lee Wyatt (last updated August 26, 2022)
If you are finding a bunch of water lining your toilet, but can't find a leak, then chances are you have a sweating toilet. In severe cases this rather common problem will appear as a leak, luckily it isn't all that difficult to fix. Usually the problem is due to condensation from the water being a dramatically different temperature from the air that surrounds it. To stop your toilet from sweating, all you need to do is follow these simple directions.
- Tank insulating kit
- Several large towels
- Tape measure
- Large sponge
- Utility knife
- Adhesive if required
- Drain your tank. The very first thing that you need to do when trying to stop your toilet from sweating is to drain the tank. Turn the water shutoff valve until it stops feeding water to the tank. With the water shut off, flush your toilet several times until you have removed as much of the water as you possibly can. There will be a little bit of water left at the bottom, but you can easily remove this by using a large sponge.
- Measure. Once you have removed all the water, you need to get a measurement of the tank. You can do this by using a tape measure. Write this measurements down (depth, width, length) on a piece of paper and head towards your local home improvement store.
- Find insulation kit. With the measurements in hand, look around the home improvement store to find a tank insulation kit that will fit. At this time if you don't already have one, you should purchase a utility knife. Take your purchase home.
- Become familiar with the instructions. Open your insulation kit and see if you can find any instructions. If you can, then become as familiar with the instructions as is possible since this will tell you the manufacturer's recommendations for installation.
- Install. If you need to begin cutting the insulating foam to the measurements of your toilet tank that you took earlier. Once you have the foam to the proper measurements you may need to apply some adhesive on the exterior edges of the foam to help keep it stuck to the interior of the tank.
- Test and clean. Once you have installed the insulation, you need to refill the water tank of your toilet. When the tank if full, test flushing a couple of times. You should notice no change in the performance of your toilet, and the condensation problem should now be a thing of the past. Clean up your tools and supplies, and enjoy your new condensation free toilet.
