How to Install a New Toilet

Here are the steps involved in installing a new toilet:


1st Step: Fix the New Mounting Bolts and Wax Ring

Don’t forget to shut off the water supply before the installation.  This will prevent leaks and drips, keeping the work environment in a clean and manageable condition.  You are now prepared to fit your new toilet.

The first step is to secure the mounting bolts, one of the components of your new toilet, to the bathroom floor. Affix it to where the old holes are on the flange. Also, place the new wax ring on the flange, which is connected to the sewer pipe, to prevent drips.

Ensure you handle the wax with care to avoid making a mess since it is sticky.


2nd Step: Affix the Toilet and Secure the Nuts

Now, gradually and carefully lower your new toilet over the mounting bolts. Ensure they are properly positioned over the holes. This is important because any misalignment will cause your toilet to feel wobbly or leak.

After the bolts are secured through the holes and correctly positioned, you can fasten them with nuts. Ensure you don’t overtighten since it can result in damage to the toilet floor.

Now that you have properly fitted your new toilet, let’s explore the third step.


3rd Step: Fit Your New Cistern

The next step is to fit your new cistern. If your toilet is a one-piece, where your toilet and cistern are not separated, then you can skip this step.

However, if your toilet’s cistern and bowl are not connected together, carefully lift the cistern and affix it to the body of the toilet with the nut and wrench.


4th Step: Turn on the Water Supply

Now that you have completed your toilet installation, you can connect the water supply to your toilet. Don’t forget that there might be some leaks.


5th Step: Check for Leaks

It is important to make sure your project is smooth and problem-free. Look around for leaks or drips. Check the sewer pipe and flush several times to ensure your toilet is properly functional.


How much does a plumber charge to replace a toilet?

Most plumbers typically charge £40 to £60 per hour, and this depends on the kind of toilet you want, your location, and if you require additional plumbing service.

Let’s analyse them in full detail:


Kind of Toilet

An important factor that can impact the overall cost of the toilet installation project is the kind of toilet.  A low-level cistern has an average installation cost of around £275 to £430, while a high-level cistern averagely costs around £300 to £480.

Close-coupled toilet £200-£400
Hidden or wall-hung cistern £550-£800

Additional Plumbing Services

If you need any further plumbing services during the toilet installation, this can affect the labour expenses of the project. And since most plumbers will charge between £40 and £60 per hour, plumbing services that take longer will incur a higher cost.
