Installing a toilet isn’t just about connecting pipes—it involves precision, the right tools, and some basic plumbing knowledge. Whether you’re replacing an old unit or upgrading your bathroom, here are a few important things to consider before diving in.
1. Check the Rough-In Measurement
The rough-in is the distance from the wall to the center of the drainpipe. Most toilets have a 12-inch rough-in, but older homes may vary. Always measure before buying a new toilet to ensure a proper fit.
2. Inspect the Flange and Floor
Before placing the new toilet, inspect the flange (the drainpipe fitting) for cracks or wear. A damaged flange should be replaced or repaired to prevent leaks. Make sure the floor is level and stable, too.
3. Use a Quality Wax Ring or Seal
The wax ring is essential for creating a watertight seal between the toilet and the drain. Some people opt for rubber or foam seals, but whatever you choose, proper alignment is key during installation.
4. Tighten with Care
Over-tightening bolts can crack the porcelain base. Instead, tighten the bolts gradually and evenly on both sides to keep the toilet level and stable.
5. Finishing Touches Matter
Once the toilet is secured, reconnect the water line, turn on the supply, and test for leaks. Apply caulk around the base if desired—it not only looks neat but helps keep things clean.
