Transform Your Bathroom: Ultimate Guide to Flooring Under Toilet Flanges

The question of whether flooring should go under the toilet flange is a common one among homeowners and flooring installers. While there is no definitive answer that applies to all situations, there are several factors to consider when making this decision.

Factors to Consider

• Type of Flooring: Different types of flooring materials have different requirements when it comes to installation and compatibility with the toilet flange. For example, rigid materials like ceramic tile or stone may need to be cut around the flange, while flexible materials like vinyl or laminate can be installed over it.
• Toilet Flange Location: The location of the toilet flange can also influence whether flooring should go under it. If the flange is recessed into the subfloor, it may be necessary to install flooring under it to create a level surface for the toilet.
• Subfloor Type: The type of subfloor can also affect the installation process. For example, plywood subfloors may require additional support under the toilet flange, while concrete subfloors may not.
• Building Codes: Local building codes may have specific requirements regarding the installation of flooring under toilet flanges. It is important to check with your local authorities to ensure compliance.

General Guidelines

In general, it is recommended to install flooring under the toilet flange in most cases. This helps to provide a solid and level base for the toilet, preventing it from rocking or shifting. However, there are some exceptions to this rule, such as:

• Flanges that are recessed into the subfloor: In this case, it may be necessary to install flooring over the flange to create a level surface.
• Flanges that are installed on a concrete subfloor: Concrete subfloors are typically strong enough to support the toilet without additional support.

Step-by-Step Installation Guide

If you decide to install flooring under the toilet flange, follow these steps:

1. Cut the flooring around the flange: Use a sharp knife or utility blade to carefully cut the flooring around the perimeter of the flange.
2. Install the toilet flange: Follow the manufacturer’s instructions for installing the toilet flange.
3. Install the flooring: Install the flooring up to the edge of the flange.
4. Cut a hole for the toilet: Use a hole saw to cut a hole in the flooring for the toilet base.
5. Install the toilet: Set the toilet in place and secure it to the flange.

Sealing the Toilet Flange

Once the flooring and toilet are installed, it is important to seal the gap between the flange and the flooring. This will help to prevent water leaks and damage to the subfloor. Use a silicone-based caulk or sealant to fill the gap around the flange.

Types of Toilet Flanges

There are several different types of toilet flanges available, each with its own advantages and disadvantages.

• Wax ring flanges: These flanges are made of metal and are installed with a wax ring to create a watertight seal.
• Flanges with rubber gaskets: These flanges have a rubber gasket that creates a watertight seal between the flange and the toilet base.
• Flanges with built-in bolts: These flanges have bolts that extend through the subfloor and secure the toilet to the floor.

Troubleshooting Toilet Flange Issues

If you encounter any problems with your toilet flange, there are several troubleshooting steps you can take:

• Check for loose bolts: If the toilet is rocking or shifting, the bolts may be loose. Tighten the bolts using a wrench or socket set.
• Replace the wax ring: If the toilet is leaking water, the wax ring may need to be replaced. Remove the toilet and install a new wax ring.
• Inspect the flange for cracks or damage: If the flange is cracked or damaged, it may need to be replaced. Consult with a plumber for professional assistance.
