The short answer
Prepare the Work Area
Start by turning off the water supply to the toilet. This is usually a valve on the wall behind the toilet, sometimes near the floor. Flush the toilet to drain as much water as possible, then sponge out the remaining water from the bowl and tank.
Place old towels or a shallow pan under the toilet to catch any drips. Remove the nuts that hold the toilet to the floor, then carefully lift the toilet straight up. Set it on its side on a padded surface so you can access the wax ring at the base.
If you live in Layton, keep your shutoff valve location written down for future reference.

- Set the toilet on its side on padding
Remove the Old Ring
The wax ring is the black or brown ring that seals the toilet to the flange. Use a putty knife or a flat screwdriver to scrape it away from the toilet's horn and the floor flange. You may need to cut through the wax with a utility knife if it is hard.
Once the old ring is off, clean the flange and the base of the toilet with a rag and a mild cleaner. Make sure the surfaces are dry and clear of old wax or debris. A clean surface helps the new ring seal properly.
If you notice water damage around the flange, such as soft wood or stains, address that before installing the new ring. Use a moisture meter to check the subfloor if you have one.
Install the New Wax Ring
Place the new wax ring onto the floor flange, aligning the opening with the drain pipe. Press it down firmly so it sits evenly. Some wax rings have a plastic horn that inserts into the flange; ensure it is centered.
Carefully lower the toilet back onto the wax ring, making sure the bolts line up with the holes in the base. Sit on the toilet or press down gently to seat it into the wax. Then re-tighten the nuts, but do not over-tighten, as that can crack the porcelain.
Reconnect the water supply and turn the valve back on. Check for leaks around the base. If water seeps out, the ring may not be seated correctly, so lift the toilet and try again.
Check for Water Damage
A wax ring failure often leads to slow leaks that damage the subfloor and surrounding drywall. After replacing the ring, inspect the area for signs of moisture, like dark spots, warped wood, or a musty smell. Use a moisture meter to probe the floor and baseboards.
If you find water damage, you may need to dry the area thoroughly before reinstalling the toilet. A wet vacuum can remove standing water, and fans or a dehumidifier help dry out porous materials. In severe cases, the subfloor may need replacement.
For extensive damage, consider professional help. Local water damage pros can handle structural drying and repairs if the damage is beyond a simple ring swap.
Know When to Call the Pros
Replacing a wax ring is a manageable DIY task for most homeowners. However, if the toilet has been leaking for a long time, the damage may be hidden. You might find soft floorboards, mold growth, or water stains on the ceiling below.
If you suspect significant water damage, do not just reinstall the toilet. Address the moisture first. You may need to remove the flooring and dry the subfloor completely. In cases of mold or rot, a mold professional or a general contractor can help.
If the damage is extensive, local water damage pros can handle the drying and repairs. They have the equipment to dry out walls and subfloors and can assess whether any structural work is needed.
- Soft or spongy floor around the toilet
- Mold or musty odor in the bathroom
- Water stains on the ceiling below
- Prolonged leaking before the repair
- Difficulty seating the new ring properly

How long does a wax ring last?
A wax ring can last many years, but it depends on the quality of the installation and how often the toilet is used. Over time, the wax can harden or crack, leading to leaks. Check for signs of water damage annually.
Can I reuse the old wax ring?
No, you should always replace a wax ring with a new one. Old rings lose their seal and can harbor bacteria. A new ring ensures a proper fit and reduces the risk of future leaks.
What if the toilet still leaks after replacing the ring?
If the toilet leaks after replacing the wax ring, the ring may be misaligned or the flange may be damaged. Lift the toilet, check the ring's position, and ensure the flange is clean. If the problem continues, the subfloor might be uneven, and you may need professional help.
