How to Replace a Toilet: A DIY Guide for Homeowners
Replacing a toilet might sound like a daunting task, but with the right tools and a little patience, it's a manageable DIY project for homeowners. Whether your toilet is old, leaking, or you simply want an upgrade, this step‑by‑step guide will walk you through the process of replacing a toilet without the need for a plumber.
Tools and Materials You'll Need
Before getting started, make sure you have the following tools and materials on hand:
- New toilet (bowl and tank)
- Toilet wax ring (or rubber seal)
- Wrench or adjustable pliers
- Toilet bolts and nuts (typically included with the new toilet)
- Screwdriver
- Utility knife
- Bucket or towel (for any water spills)
- Sponge or wet/dry vacuum (to remove excess water)
- Plumber's tape (optional, for the water supply connection)
Step 1: Turn Off the Water Supply
First, locate the water shut‑off valve behind the toilet. Turn the valve clockwise to shut off the water supply. After that, flush the toilet to drain the tank and the bowl. You may need to use a sponge or towel to soak up any remaining water in the tank and bowl.
Step 2: Disconnect the Water Line
Next, use your wrench or adjustable pliers to disconnect the water supply line from the toilet's fill valve. Be sure to place a bucket or towel under the connection to catch any leftover water that might spill.
Step 3: Remove the Old Toilet
Now it's time to remove the old toilet. Begin by unscrewing the toilet bolts and nuts that secure the toilet to the floor. These bolts are usually covered with decorative caps, which you can remove with a screwdriver . Once the caps are off, use a wrench to loosen and remove the bolts.
After the bolts are removed, gently rock the toilet back and forth to break the seal with the wax ring. You may need to use a utility knife to cut through the wax ring if it's particularly stuck. Once the toilet is free, carefully lift it off the flange and set it aside.
Step 4: Remove the Old Wax Ring
The wax ring (or rubber seal) that sits on the flange is likely stuck to the bottom of the old toilet. Use a putty knife to scrape away the wax and any debris from the flange. Be careful not to damage the flange or the floor. It's important to clean this area thoroughly before installing the new toilet.
Step 5: Install New Toilet Bolts
With the old toilet removed, place new toilet bolts into the flange. Most new toilets come with fresh bolts, but if not, you can easily buy them at any hardware store. Ensure the bolts are positioned upright and straight, as they'll need to align with the new toilet's mounting holes.
Step 6: Apply the New Wax Ring
Now it's time to install the toilet wax ring (or rubber seal). Place the wax ring on top of the flange, ensuring it is centered. If you're using a rubber seal instead of a wax ring, follow the manufacturer's instructions for installation. The wax ring forms a watertight seal between the toilet and the floor, preventing leaks.
Step 7: Place the New Toilet
Carefully lower the new toilet onto the flange, making sure the toilet bolts align with the mounting holes in the base of the toilet. Press down gently to ensure the toilet is securely positioned and the wax ring is compressed. Make sure the toilet is level before moving on.
Step 8: Secure the Toilet
Once the toilet is in place, use your wrench to tighten the nuts onto the toilet bolts. Be careful not to overtighten, as this can crack the toilet base. Tighten the bolts evenly to ensure the toilet is secure and does not rock.
Step 9: Reconnect the Water Line
Next, reconnect the water supply line to the fill valve on the toilet. If the old water line looks worn or damaged, it's a good idea to replace it with a new one. Tighten the connection by hand, then use pliers to ensure it's secure. Again, be careful not to overtighten.
Step 10: Test the Toilet
Once everything is connected, turn the water supply back on by turning the shut‑off valve counterclockwise. Let the tank fill, and then flush the toilet a few times to check for leaks around the base or the water supply connection.
If you notice any leaks, turn off the water supply and tighten any loose connections. If the toilet rocks, you may need to adjust the bolts or add shims to stabilize it.
Step 11: Finish Up
Once the toilet is securely in place and functioning properly, replace the decorative bolt caps over the toilet bolts. Clean up any mess, and you're done!
