Installing a toilet might look straightforward, but there are a few important details you should know before getting started. A well-installed toilet ensures long-term performance, prevents leaks, and saves you from future plumbing headaches.

1. Measure the Rough-In

The rough-in is the distance from the wall to the center of the toilet flange (the pipe opening on the floor). Most standard toilets require a 12-inch rough-in, but it's essential to measure yours before buying a new toilet to ensure a proper fit.

2. Check the Condition of the Flange

The toilet flange needs to be clean, level, and free of cracks. If the flange is damaged, it should be repaired or replaced before installation—this is key to preventing leaks.

3. Use a Proper Seal

A wax ring (or a modern rubber seal) sits between the toilet base and the flange, creating a watertight barrier. Positioning the toilet directly over the seal without shifting is critical for a good connection.

4. Secure the Toilet Evenly

When tightening bolts, apply even pressure on both sides. Over-tightening can crack the toilet base, while loose bolts can lead to wobbling or leaks. Always double-check that the toilet sits level.

5. Reconnect Water Supply and Test

After installing the toilet, attach the water supply line and turn the valve on. Check for any leaks around the base or tank, and make sure the toilet flushes properly.
