Understanding Toilet Types
Toilets can come in different prices, sizes, and installation needs. Here’s a quick preview of some common toilet types:
Close-Coupled: Simple to install and widely used, this type has the cistern placed directly on the toilet.
Back-to-Wall: Offers a modern appearance with a concealed cistern, but installation is more complex.
Wall-Hung: This design appears to float, saving floor space, but requires a sturdy wall frame for support.
High/Low-Level Cisterns: This classic design allows you to position the cistern either high or low on the wall.
Specialist/Hands-Free: Typically pricier, these are commonly seen in luxury or accessible bathrooms.
The toilet bowl replacement cost depends on the type of toilet you choose. Most standard bowl replacements are priced between £80 and £200.
How Long Does It Take to Fit a Toilet?
A typical toilet replacement takes about 2 to 4 hours, depending on your plumbing and the model of toilet. But how long does it take to fit a toilet can vary. Some high-spec models or installations involving hidden pipework may take most of the day.
What Else Might Affect the Price?
Your final quote may include extra work. Here are common add-ons and their average costs:
| Extra Work | Estimated Cost (Initial Prices) |
| Removal and disposal of an old toilet | £75 |
| Altering pipework | £150 |
| Building wall frames for hidden cisterns | £350 |
| Emergency or weekend callouts | £100+ |
If you’re also building a cloakroom, the small extension for downstairs toilet cost can range from £4,000 to £8,000, including plumbing, flooring, and basic finishes.
Labour and Toilet Fitting Cost
Plumbers usually charge:
- Hourly: £40–£60
- Day rate: £320–£480
This means even if you’re only replacing the toilet, your toilet fitting cost could go up if the plumber runs into hidden problems, such as leaking pipes or worn connectors.
Can You Do It Yourself?
If you’re good with the tools and know some techniques, you might try giving DIY a chance. But that would fall into poor workmanship because you might not know the cause of the problem. It’s important to know how to replace a toilet cistern or a full toilet before starting. Mistakes in DIY projects can result in water damage, leaks, and expensive repairs. By hiring a professional plumber, you can ensure compliance with building regulations and receive a warranty for their services.
How to Save Money on Toilet Replacement
Here are some tips to manage your toilet installation expenses:
- Purchase your own toilet: Find and buy the toilet and materials on your own.
- Request multiple estimates: Obtain 2–3 quotes to ensure you don’t pay too much.
- Steer clear of emergency services: Schedule work during the week to reduce hourly rates.
- Combine tasks: If you’re renovating the entire bathroom, group jobs together to lower overall labor costs.
When Should You Replace a Toilet?
It might be time to replace your toilet if you notice:
- There are leaks from the tank or base.
- There are cracks in the ceramic.
- The seat feels unsteady or shaky.
- The system is experiencing regular clogs or a weak flush.
- Increased water bills due to outdated models.
Also, if your toilet takes up too much space, switching to a compact design with the average toilet size (about 680mm depth and 360–390mm width) could free up room—especially useful in smaller bathrooms.
