Types of Toilet Installation
Close-Coupled Toilet
The most common toilet type in UK homes. The cistern sits directly on the pan, which usually makes this the cheapest and simplest option to replace.
Pros
- Usually the lowest installation cost
- Easy to source and replace
- Suits most standard bathrooms
Cons
- Less sleek than concealed options
- Can take up more visual space
Best for: Straightforward bathroom upgrades where practicality and value matter most
Back-to-Wall or Concealed Cistern Toilet
This setup hides pipework and the cistern behind furniture or a wall frame, creating a cleaner finish but increasing labour and build work.
Pros
- Cleaner, more modern appearance
- Hides pipework and cistern
- Can work well in contemporary bathrooms
Cons
- More expensive to fit
- May need boxing, framing, or furniture work
Best for: Bathrooms where appearance is a priority and extra fitting work is acceptable
Wall-Hung Toilet
A wall-hung toilet is mounted off the floor with the cistern concealed inside a frame. It gives a premium look but needs stronger support and more installation work.
Pros
- Premium, space-enhancing look
- Easier to clean underneath
- Good for modern renovations
Cons
- Higher product and labour costs
- Needs secure framing and accurate installation
Best for: Higher-spec bathrooms where design and clean lines are a priority
The final price depends heavily on the toilet style you choose and whether the new toilet can be fitted into the existing layout without major alterations.
What Affects the Cost
- Whether the replacement is like-for-like or needs plumbing changes
- Toilet style, including standard, concealed, or wall-hung
- Condition and position of the existing waste pipe
- Whether tiling, boxing, or making good is needed afterward
- Access to the bathroom and shut-off arrangements
- Whether the old toilet needs removal and disposal
Labour Cost Breakdown
Labour is typically 30–50% of the total installation cost. The complexity of the job determines how long it takes.
What Is Usually Included
- Isolation and removal of the old toilet
- Positioning and fitting of the new pan and cistern
- Connection to water feed and waste
- Basic sealant application and leak testing
- Commissioning and flush check
Extra Costs to Expect
These aren't always required, but it's worth knowing about them before you get quotes.
Running Costs & Potential Savings
A newer toilet may help reduce water use if you are replacing an older, less efficient model. Long-term value usually comes from lower maintenance, fewer leaks, and a cleaner, more reliable installation.

Frequently Asked Questions
How much does it cost to install a toilet in the UK?
A straightforward replacement can be relatively inexpensive, but concealed or relocated toilets cost more. Most jobs land somewhere between a few hundred pounds and well over GBP 1,000 for more complex work.
Is it cheaper to replace a toilet like for like?
Yes. Keeping the new toilet in the same position usually avoids extra waste pipe and feed pipe changes, which keeps labour costs lower.
Do wall-hung toilets cost more to fit?
Usually yes. They often need stronger framing, concealed cistern work, and more precise installation than a standard close-coupled toilet.
How long does toilet installation take?
A basic replacement can often be finished within a few hours. More complex jobs can take a full day or longer.
Will a plumber remove the old toilet?
Often yes, but not every quote includes disposal. It is worth checking whether removal and waste disposal are both covered.
What usually pushes the price up?
The biggest cost increases usually come from concealed cistern systems, waste pipe changes, boxing work, wall frames, and finishing repairs afterward.
