The toilet flange should be 1/4” above the finished floor to allow the toilet to make a water tight seal. However, while installing tile in the bathroom, many people simply tile right up to the flange. This often leaves the toilet flange below floor level. An easy fix for this problem is to install a toilet flange extension.
Time Required: 15 minutes
- Start by cleaning off the old flange to ensure that the flange extension can sit neatly in place.
- Next, apply a liberal amount of caulk on the bottom of the flange extension and set it into place. Make sure to align the bolt holes of the flange extension with those of the old flange.
- Slip the bolts into place followed by the accompanying nuts. Tighten nuts with a pair of pliers.
- When the flange extension is set in place and the toilet flange is once again 1/4” above floor level, you can proceed with setting the toilet using a deep seal bowl wax.
- If one flange extension is not enough to bring the flange to the right height you can use more than one. Just be sure to use caulk between each flange extension.
- Longer closet bolts are available for purchase if the standard bolts are not long enough to hold the toilet in place after installing the flange extension.
