1. Start With the Right Measurements
One of the first things to check is the rough-in measurement, which is the distance from the wall to the center of the drainpipe (flange). Most standard toilets use a 12-inch rough-in, but you’ll want to double-check this before purchasing your toilet.
2. Inspect the Toilet Flange and Floor Condition
Make sure the flange is clean, level, and securely fastened. A cracked or misaligned flange can cause leaks or make the toilet sit unevenly. The subfloor should also be stable and dry to prevent future damage.
3. Choose the Correct Seal
A wax ring or rubber gasket provides the watertight seal between the toilet and flange. Installing this properly is critical—if it’s misaligned, you could face nasty leaks.
4. Tighten Bolts Evenly and Cautiously
When securing the toilet to the floor, avoid over-tightening the bolts. Doing so can crack the porcelain. Tighten gradually, alternating sides, to create a secure but balanced fit.
5. Reconnect the Water and Test Thoroughly
Once the toilet is installed, attach the water line, turn it on, and test the flush several times. Watch for leaks at the base and supply connection. If everything stays dry and the toilet doesn’t rock, your installation was a success.
