Successfully Replacing Your Toilet: A Step-by-Step Guide

Whether you're looking to upgrade to a more efficient model or simply need to replace a broken toilet, changing a toilet might seem daunting. However, with the right tools and techniques, this task can be tackled by even the most novice DIY enthusiasts. In this guide, we’ll explore everything you need to know about replacing your toilet, from preparation to the final installation.

🛠️ Tools and Materials Needed

Before diving in, ensure you have all the necessary tools and materials ready. This preparation will make the process smoother and quicker.

Essential Tools:

  • Adjustable wrench
  • Screwdriver
  • Putty knife
  • Measuring tape
  • Hacksaw (if needed for cutting bolts)
  • Level

Necessary Materials:

  • New toilet
  • Wax ring
  • Toilet bolts
  • Replacement water supply hose (if old one is worn)
  • Plumber’s tape

📏 Understanding Measurements and Specifications

1. Measure the Rough-In Distance

The rough-in distance is the measurement from the wall (not the baseboard) behind the toilet to the center of the closet bolts that hold the toilet down. Standard measurements are typically 12 inches, but 10-inch and 14-inch models are also available.

2. Check the Dimensions of Your New Toilet

Ensure the new toilet fits comfortably into the space. Consider the height, especially if you prefer a comfort-height toilet.

🏠 Preparing Your Bathroom

Before removing your existing toilet, it’s important to prep the area to prevent leaks or damage.

1. Shut Off the Water Supply

Turn off the water supply to the toilet using the valve located behind it. Flush the toilet to empty the tank and use a sponge or towel to soak up any remaining water from the tank and bowl.

2. Disconnect the Water Supply Line

Using an adjustable wrench, disconnect the water supply line from the toilet tank. Be prepared for some residual water to spill.

3. Remove the Old Toilet

  • Unscrew and Remove Caps: Using the wrench, remove the nuts from the floor bolts at the base of the toilet. Remove any decorative caps.
  • Lift and Remove: With a helper, carefully rock the toilet from side to side to break the seal of the wax ring, then lift it straight up. Place it on a drop cloth or towel.

🧽 Cleaning and Inspecting the Area

With the old toilet removed, spend some time cleaning and inspecting the installation site.

1. Clean the Flange

Scrape off any old wax using a putty knife. Carefully inspect the flange (the fitting at the floor for the toilet connection) for damage. Replace if necessary.

2. Inspect the Subfloor

Check for signs of water damage. If the floor is soft or rotted, repairs may be necessary before proceeding.

🚽 Installing the New Toilet

1. Position the Wax Ring

Place a new wax ring on the horn (outlet) of the new toilet or set it on the flange on the floor. This crucial step ensures a watertight seal.

2. Attach Toilet Bolts

Align new toilet bolts in the floor flange. Make sure they are upright and parallel.

3. Set the Toilet in Place

Carefully lower the toilet onto the flange, ensuring the bolts come through the holes on the base. Apply gentle pressure to form a seal with the wax ring.

4. Secure the Toilet

Add washers and nuts to the bolts, tightening them evenly. Avoid over-tightening as this can crack the porcelain.

5. Install the Tank (if necessary)

If your new toilet comes with a separate tank, attach it using the provided rubber gasket, bolts, and nuts. Ensure it's level and secure.

6. Connect the Water Supply

Use plumber’s tape on the tank’s threaded fill valve. Attach and tighten the supply line, ensuring no leaks are present when turned on.

🔧 Final Adjustments and Testing

1. Test the Toilet

Turn the water supply back on and allow the tank to fill. Flush and check for leaks at the base and at the connection points.

2. Apply Finishing Touches

  • Use a level to ensure the toilet is set evenly.
  • Add any included bolt cover caps for a neat finish.
  • Tighten the seat installation screws.
