Installation
Remove Old Toilet
- To replace the original toilet, shut off the water supply valve and flush tank completely. Disconnect and remove the supply line.
- Clear the sealant around the toilet base, unscrew the bolts, and remove the toilet.
- Remove closet bolts from the toilet flange and clean wax and putty using putty knife. Clean the floor.
Confirm Rough-in & Levelness
- Measure the distance from the wall to the centerline of the flange. While most bathrooms have a 12-inch (305mm) rough-in, 10-inch and 14-inch are two common rough-in sizes, too. Make sure the purchased model matches the rough-in measurement in your bathroom.
- Make sure the area for toilet is clean, dry, and level.
- Inspect existing closet flange. Replace if necessary.
- Temporarily plug the flange with a towel or flange plug.

REMINDER: When replacing the flange, always remember to lock the nuts into position to prevent the toilet from shifting over time and damaging the wax seal.
Apply Wax Gasket and Sealant
- Invert the toilet on the floor.
- Apply the wax ring gasket evenly around the rear of the trapway.
- Apply a thin bead of sealant around the toilet base.
REMINDER: Consider placing a tarp over the floor for surface protection.
Position Toilet onto Flange
- Unplug the floor opening and position the toilet on the flange so the closet bolts project through the pre-drilled holes around the rear of the toilet trapway.
- Position the toilet squarely to the wall, and press down fully on the wax ring and flange to create a watertight seal. Alternately tighten nuts until the toilet is firmly seated on the floor.
- Smooth off a bead of sealant around the base. Remove any excess sealant.
- Install the washers and nuts onto the bolts. Do not over-tighten as it might crack the ceramics.
Check for Leaks
- Connect the supply line to the fill valve at the back of the toilet.
- Flush test. Make sure there is no leak from the waterline or the flange.
- Assemble cover caps. Attach to the side holes of the toilet and tighten with a screwdriver.
Toilet Seats
Quick-release Models
- To quickly remove the seat, press the button and gently pull the seat from the attached hinges.
- To quickly install the seat, press the button, align the pre-drilled holes on the seat with the hinges, and adjust the seat to align with the bowl.
NOTE: Disassembling a quick-release seat might require manual operation behind the toilet. It's recommended to install your desired bidet or other types of seat prior to floor mounting the toilet.
