Ensuring you have all these items ready before starting will set you up for a smooth and successful installation. Proper preparation is key to achieving a flawless and durable result!
Preparing the Area
Remove the Toilet
Remove the toilet before starting the tiling process to ensure a seamless and professional finish around the area. Start by turning off the water supply to the toilet. Then, flush to remove as much water as possible and use a sponge or towel to absorb any remaining water in the tank and bowl. Next, unscrew the bolts securing the toilet to the flange and gently lift the toilet off. Set the toilet aside safely, ensuring the wax ring remains intact for proper disposal or replacement later.

Inspect and Clean the Subfloor
Take this opportunity to inspect the subfloor and ensure the flange is in good condition. Any damage to the flange should be repaired or replaced as necessary. Thoroughly clean the subfloor, removing any debris, wax remnants, or adhesives. Use a leveling compound if required to create an even surface, as an uneven subfloor can lead to issues with tile placement and durability.
Install Cement Backer Board (if necessary)
If your subfloor is made of wood, installing a cement backer board is crucial for stability and moisture resistance. Cut the backer board to fit snugly, leaving a small gap around the flange for potential tile movement. Secure the board using screws, and ensure it is level and firmly in place before proceeding to the next steps.
Measuring and Cutting Tiles Around the Flange
Dry Fit Tiles
Begin by laying out the tiles around the flange without applying adhesive. This dry-fitting process allows you to visualize the final layout and make any necessary adjustments to ensure the tiles are correctly aligned. Center the layout in the room to achieve a balanced appearance, and confirm that the tiles are evenly spaced, considering the grout lines. Pay special attention to the tiles surrounding the flange, as these require precise cuts for a professional finish.
Marking Cut Lines
To mark the tiles for cutting, use a compass or create a cardboard template to trace the shape of the flange onto the tiles. This will help you outline the exact portions of each tile that need removal. Be sure to consider the width of the grout lines and leave a small expansion gap for any potential tile movement or settling. Mark these guidelines clearly on the tiles using a pencil or marker to ensure accurate cuts.
Cutting the Tiles
Cutting tiles around the flange requires the right tools and attention to detail. Make precise circular cuts using a tile nipper, hole saw, or angle grinder. A U-shaped cut may be required for larger tiles that need to fit snugly around the flange. Carefully remove the material section by section, taking your time to avoid cracking or damaging the tile. Once the cuts are complete, test fit each tile around the flange to ensure a seamless fit before moving on to the adhesive stage.

How to Tile Around a Toilet Flange: Installing the Tiles
Apply Adhesive
Spread thinset mortar evenly onto the surface using a notched trowel. Focus on working in small, manageable sections so the adhesive doesn’t dry out before the tiles are laid. Make sure to create grooves in the mortar for better adhesion, and avoid applying too much at once to maintain precision.
Lay the Tiles
Begin setting the tiles in place according to your layout plan. Use tile spacers to ensure consistent grout lines between each piece. When placing the cut tiles around the flange area, take extra care to align them correctly to achieve a uniform appearance. Gently twist or press each tile into the mortar to create a firm bond.
Check for Level and Fit
After setting the tiles, check them with a level to ensure they are even with the surrounding surface. Press down on any slightly high areas to align them or adjust as needed. It’s crucial to make sure the tiles fit snugly around the flange and maintain the overall flow of the design.
Allow the Adhesive to Cure
Once all the tiles are set, allow the thinset mortar to cure for the duration specified on the product instructions—typically around 24 hours. Refrain from walking on or disturbing the tiled area during this time to avoid shifting or loosening the tiles. Proper curing ensures a stable and long-lasting finish.
Grouting and Finishing Touches
Grouting the Tiles
Once the adhesive has cured, carefully remove all the tile spacers. Use a rubber float to apply grout over the tiled surface, holding it at a 45-degree angle to press grout into the joints effectively. Work in small sections to ensure thorough coverage. After filling the joints, wipe away excess grout from the tile surfaces using a damp sponge. Rinse the sponge frequently to avoid leaving any grout haze. Allow the grout to dry as specified in the manufacturer’s instructions.
Seal the Grout (Optional)
Sealing the grout can help protect it from stains and moisture absorption, extending its longevity. Once the grout has fully cured, typically 48-72 hours after application, apply a grout sealer with a small brush or applicator tool. Focus on the grout lines, ensuring even coverage. Allow the sealer to set and dry as directed before proceeding.
Install Toilet Flange Extender (If Needed)
If the new tiled surface has raised the floor height, installing a toilet flange extender is essential to maintain a proper seal with the toilet. Align the extender with the existing flange, ensuring it is flush with or slightly above the surface of the finished tiles. Secure the extender according to the manufacturer’s instructions to ensure a watertight connection. This step ensures a secure and functional seal for the toilet installation.

Resetting the Toilet
Install New Wax Ring and Bolts
Begin by placing a new wax ring onto the flange. Ensure that the wax ring is properly positioned for an effective seal. Next, align the closet bolts on either side of the flange, ensuring they are upright and secure to accommodate the toilet placement. This step is critical to prevent leaks and maintain toilet stability.
Position and Secure the Toilet
Carefully lift the toilet and lower it onto the flange, ensuring it is aligned and centered over the bolts. Once the toilet is in position, apply pressure to seat the wax ring gently. Use your hands to gradually tighten the bolts, alternating sides to prevent cracking the toilet’s base. Avoid overtightening, as this can damage the porcelain.
Reconnect Water Supply
Reconnect the water supply line to the tank and turn on the water valve slowly to allow the tank to fill. Inspect the area closely for leaks around the base and connection points. Finally, test flush the toilet to confirm proper operation and a secure installation. Address any minor adjustments as needed to complete the resetting process.

Conclusion
Learning how to tile around a toilet flange involves careful preparation, accurate measurements, and attention to detail during installation. Ensuring the proper flange height is critical to avoid leaking or improper sealing, which could cause long-term issues. Always prioritize precision when making cuts and applying seals, as these steps ensure a professional, long-lasting result.
Taking your time and using the right tools will give your project the polished finish it deserves, turning what may seem like a daunting task into a manageable and rewarding home improvement achievement. A well-executed job ensures both functionality and aesthetic appeal.
