We will walk you through the whole process, from removing the old fixture to toilet bowl installation and sealing, so you can confidently complete the job at home. Let’s get started!

Tools and Materials You'll Need
Before you initiate your toilet installation, make sure you have everything ready. Essential tools include:
Shifter spanner (adjustable wrench) for loosening and tightening bolts
Putty knife to remove the old wax ring and clean the flange
Sponges and buckets to soak up any leftover water from the tank or bowl
New wax ring to create a watertight seal between the toilet and flange
Toilet bolts to secure the toilet to the floor
Spirit or digital level to ensure the toilet is installed evenly
Silicone caulk for sealing around the base of the toilet
Screwdriver to tighten fittings and components
Cloth or towel to wipe away spills or water
Flush pipe to connect the cistern to the toilet bowl (for certain models)
A new toilet suite and components
With these tools and materials ready, you should be able to make your toilet install quickly and stress-free.
Removing the Old Toilet
To install a new toilet, you’ll first need to remove the old one. Here’s a simple guide to get you started.
Step 1. Shut off the water supply
Locate the shut-off valve behind the toilet and turn it clockwise to stop the water flow. This prevents leaks during the removal process.
Step 2. Empty the toilet
Flush the toilet to drain water from the tank and bowl. Use a sponge, towel, or bucket to remove any leftover water so the unit is completely dry before lifting.
Step 3. Detach the water supply line
Using a shifter spanner (adjustable wrench), disconnect the water supply line from the toilet tank. Keep a cloth or towel handy for any drips.
Step 4. Remove the toilet tank
Use a wrench to loosen the bolts connecting the tank to the bowl. Once free, lift the tank straight up and place it on a towel or flat surface. Removing the tank first makes the toilet lighter and much easier to handle.
Step 5. Unfasten and lift the toilet bowl
Unscrew the toilet floor bolts with your wrench, gently rock the bowl to break the wax seal, and lift it off the flange.
Step 6. Clean the toilet flange
Scrape away the old wax ring using a putty knife and check the flange for cracks or damage. If necessary, replace the flange before proceeding with your new toilet commode installation.
After you complete these steps, you should have a clean and ready foundation. Next, let’s see how to put in a new toilet step by step.
Installing a New Toilet
Now that the old unit is removed, you can move on to the next stage of your toilet installation. If you’re new to DIY, Close-Coupled Toilets are a great example to start with. They’re one of the easiest types to install since the cistern sits directly on the pan, making the whole process simpler. Let’s walk through the steps to attach a toilet together.
Step 1. Prepare the flange with a seal
Position a new wax ring on the toilet flange. You can also use a wax-free silicone ring, which allows you to put in the toilet in a less messy way.
Step 2. Set the toilet bowl in place
Gently place the toilet bowl over the flange, guiding it onto the bolts. Press straight down so the seal sits evenly without shifting.
Step 3. Secure the toilet bowl
Place washers and nuts onto the bolts, then tighten them a little at a time on each side. Stop once the bowl feels firm; too much force can crack the ceramic.
Step 4. Install toilet cistern
This is a key step in how to mount a toilet properly. Position the cistern onto the bowl (pan), ensuring it sits evenly and securely.
Step 5. Connect the flush pipe
Attach the flush pipe between the pan and the cistern, making sure seals are intact and properly positioned. Make sure it’s a snug fit that maintains proper water flow and prevents leaks.
Step 6. Reconnect the water supply line
Use a wrench to reattach the water supply line to the cistern. Turn the valve back on and allow the tank to fill.
Step 7. Attach the toilet seat
Install the toilet seat according to the instructions, ensuring it is aligned correctly and tightened securely.
Step 8. Test and finish
Flush several times to check water flow and leaks. Seal around the base with silicone for a neat, moisture-resistant finish.

FAQs
How Long Does It Typically Take To Install a Toilet As a Beginner?
For beginners, a toilet installation usually takes 2–4 hours. This includes shutting off the water, removing the old unit, cleaning the flange, setting a new wax ring, and securing the bowl. Testing for leaks is also part of the process. Keep in mind that time may vary depending on the toilet type. Close-Coupled Toilets are faster to install, while In Wall Toilet Suites are more complex and generally require professional installation.
Do I Need to Replace the Wax Ring Every Time I Reinstall the Toilet?
Yes. You should always replace the wax ring when reinstalling or moving a toilet. Wax rings lose their shape once compressed, which means they cannot reseal properly if reused. A new wax or silicone ring ensures a tight, watertight seal and prevents leaks around the toilet base. It’s a small, inexpensive part, but skipping it can lead to water damage and costly repairs later.
When Is It Best to Call a Professional Instead of DIY?
DIY toilet installation is possible in most cases, but there are situations where a licensed plumber is the safer choice. For example, if the toilet flange is broken, the subfloor is uneven, or you’re dealing with persistent leaks, professional expertise is essential. It’s also wise to hire a plumber if you’re installing complex toilet types like In Wall Toilet Suites. These systems require precise fitting and concealed connections that are best handled by an expert.
