Whether you’re facing constant clogs, a leaky flush, or the worrying sight of a fine porcelain crack, replacing your toilet can be a sensible step. If you’re fitting a new bathroom or downstairs toilet, then you’ll want your toilet to match your other sanitaryware without breaking the bank.
Whatever the reason, toilet replacement doesn’t have to be a hassle, especially when you can hire a professional plumber through HaMuch to take care of everything for you. We’ll go through everything you need to know about the costs of a new toilet in this guide.
How much it costs to replace a toilet depends on a few factors, such as whether it’s a like-for-like swap, the kind of toilet it is and where you live. Expect to pay at least £150 for a like-for-like swap of a close-coupled toilet.

As with most plumbing jobs, there are a few factors that can affect the cost of toilet replacement. A straight like-for-like swap is usually quicker and cheaper than replacing a close-coupled toilet with a wall-hung or high-level toilet.
Other things that affect the price include:

There are a few different types of toilets to choose from. The type of toilet you choose depends on your bathroom’s style, any accessibility needs and your budget:
Close-coupled toilets are the traditional type of toilet. The cistern sits on the back of the toilet bowl and may have a button flush or a handle flush. They are usually the most cost-effective type of toilet to buy, starting at around £100.
Wall-hung or hidden cistern toilets are becoming more popular due to their stylish look that keeps the cistern hidden behind a wall. They are usually more expensive than close-coupled toilets, starting at around £230.
If you are replacing a close-coupled toilet with a wall-hung one, don’t forget to factor in costs for wall support, boxing in and tiling or bathroom cladding to cover the cistern.
High-level toilets have that traditional Victorian look where the cistern is mounted up high on the wall connected by a flush pipe. They usually have a chain pull flush. Common in period homes and restaurants where cubicle space is at a premium, these toilets start at around £280.
Low-level toilets have their cistern mounted lower on the wall than high-level toilets, but it’s still higher than on a close-coupled toilet and is connected by a flush pipe. They may have a handle or button flush, and typically start from around £150.
If you prefer to buy trusted brands, there are lots of toilet brands to choose from. Some of the most popular in the UK right now include:

Most toilet installations involve removing the old toilet, preparing the area, and fitting the new one onto existing plumbing. If the pipework is in good condition, the job is relatively straightforward. If the pipes are corroded or outdated, the plumber will need to replace them before fitting the new toilet.
The steps typically include:
If you want to install a toilet somewhere that doesn’t have an existing waste pipe, such as a basement or loft conversion, you might need a macerator toilet like a Saniflo. These toilets grind up waste and pump it through small pipes to the main drainage system.
Saniflo toilets don’t rely on gravity, so they can be installed in places where traditional toilets aren’t an option. They do, however, require a reliable power supply and can be more expensive to maintain over time.
Expect to pay at least £1,000 for the supply and installation of a new macerator toilet in a new location.
Most toilet repairs, such as fixing a constantly running cistern or replacing a flush valve, only require a plumber for an hour or two. Parts are typically inexpensive – a bottom-entry flush valve might cost around £15, while a new cistern starts from £50. A basic replacement toilet seat can cost as little as £10, while soft-close and designer seats range from £20 to £70 or more.
Many plumbers will have a minimum charge of one hour, even if the work takes less time, to cover their travel costs. The average hourly rate for a plumber is £60.
If your toilet is fairly modern and the issue is minor, such as a faulty valve or flusher, a repair will usually be cheaper. But if the bowl is cracked, leaks persist, or you’ve already made several repairs, replacement is often the most cost-effective and reliable option in the long run.
