Toilet Shims 101: Everything You Need to Know about Using and Installing Toilet Shims

What are Toilet Shims?

Toilet shims are small plastic or rubber accessories that are used to stabilize and level a toilet on an uneven floor. They are designed to fill the gap between the toilet bowl and the floor, preventing the unit from rocking or wobbling when someone sits on it.

Why are Toilet Shims Important?

Using toilet shims is essential to ensure that your toilet is firmly anchored to the floor. An unsteady toilet can cause leaks, damage to the flange or wax seal, and even breakage of the toilet itself. Additionally, an unstable toilet can be a hazard that could cause injuries to people using it.

How to Install Toilet Shims

Installing toilet shims is a relatively easy process that can be done in just a few minutes. Here is a step-by-step guide:

1. Turn off the water supply and flush the toilet to empty the bowl and tank.
2. Loosen the bolts on the base of the toilet using a wrench.
3. Remove any old wax seals or debris from the floor flange and the toilet base.
4. Place the toilet shims around the flange, making sure they are evenly spaced.
5. Lower the toilet onto the shims, making sure it is centered and level.
6. Tighten the bolts at the base of the toilet, being careful not to overtighten them.
7. Trim any excess shim material using a utility knife or scissors.
8. Turn on the water supply and check for leaks.

Types of Toilet Shims

There are various types of toilet shims available on the market, including:

• Plastic toilet shims: these are made of hard plastic and are the most commonly used type of shim. They are affordable, durable, and easy to work with.
• Rubber toilet shims: these are made of soft rubber and are ideal for use on delicate flooring, such as wooden floors. They are more expensive than plastic shims but are also more flexible and absorb vibrations better.
• Foam toilet shims: these are made of soft foam and are designed to be compressed under the weight of the toilet, providing a firm and stable base. They are the least expensive type of shim, but they may compress over time and lose their effectiveness.

Wrapping Up

Toilet shims are an affordable, easy-to-use solution for stabilizing a wobbly or unstable toilet. They can prevent leaks, damage, and even injuries, making them an essential component of any bathroom renovation or repair. When using toilet shims, it is important to choose the right type of shim for your flooring and to install them correctly for maximum effectiveness.
