Installing a toilet flange in new construction is a crucial step in creating a functional and durable bathroom setup. Whether you’re a seasoned plumber or a DIY enthusiast, following the proper steps will ensure a secure and leak-free installation.
Materials You’ll Need
- Toilet flange
- Toilet flange seal
- Wax ring
- Bolts and washers
- Screwdriver or wrench
- Measuring tape
- Pencil or marker
- Hacksaw or pipe cutter
- Plumber’s putty (optional)
Step 1: Measure and Mark the Location
- Determine the location of the toilet and mark the center point on the subfloor.
- Measure 12 inches from the center point and draw a circle with a radius of 6 inches. This will be the outline for the flange.
Step 2: Cut the Subfloor
- Use a hacksaw or pipe cutter to cut the subfloor along the circle you drew.
- Be careful not to cut into any pipes or wires below the subfloor.
Step 3: Install the Toilet Flange
- Place the toilet flange seal over the hole in the subfloor.
- Position the toilet flange over the seal and align the bolts with the holes in the subfloor.
- Secure the flange using the bolts and washers. Tighten the bolts until the flange is snug but not overtightened.
Step 4: Apply Plumber’s Putty (Optional)
- Apply a ring of plumber’s putty around the base of the flange, inside the circle you cut.
- This will help create a watertight seal between the flange and the subfloor.
Step 5: Install the Wax Ring
- Place the wax ring on the bottom of the toilet, aligning the holes in the ring with the bolts.
- Press down on the toilet to seat the wax ring correctly.
Step 6: Tighten the Toilet Bolts
- Use a screwdriver or wrench to tighten the bolts that secure the toilet to the flange.
- Tighten the bolts evenly and gradually to avoid cracking the toilet or damaging the flange.
Step 7: Check for Leaks
- Turn on the water supply to the toilet and flush it several times.
- Check for any leaks around the base of the toilet or the flange.
- If you notice any leaks, tighten the bolts further or adjust the wax ring.
