Types of Bathroom Installation
Like-for-Like Bathroom Replacement
The existing bath, toilet, basin, and shower are replaced in roughly the same positions. This is usually the most cost-effective full bathroom route.
Pros
- Usually the cheapest full renovation route
- Less disruption to plumbing layout
- Faster than a full redesign
Cons
- Less flexibility to improve the layout
- Still can become costly with premium finishes
Best for: Bathrooms where the current layout still works well
Full Bathroom Redesign
This involves changing the layout, replacing finishes, and often combining fitting, plumbing, tiling, and electrical work into one larger project.
Pros
- Lets you improve how the room functions
- More flexibility on shower, bath, and storage positions
- Can deliver a more premium finished result
Cons
- More expensive than like-for-like replacement
- Longer installation time
Best for: Bathrooms with awkward layouts or bigger design ambitions
Ensuite or Compact Bathroom Fit-Out
A smaller bathroom or ensuite can cost less in some areas, but compact rooms can still be fiddly and labour-intensive depending on the specification.
Pros
- Can create valuable extra convenience
- May use less material than a larger bathroom
- Works well for loft or bedroom projects
Cons
- Tight spaces can still be labour-heavy
- Premium compact fittings can be expensive
Best for: Ensuites, cloakroom conversions, and compact family bathrooms
Bathroom costs vary most between a basic like-for-like refurbishment and a full redesign with premium fittings, extensive tiling, and layout changes.
What Affects the Cost
- Bathroom size and room shape
- Whether the layout stays the same or changes
- Specification of the suite, brassware, and furniture
- Amount of wall and floor tiling required
- Condition of existing plumbing, walls, and floors
- Electrical work, extraction, lighting, and heating upgrades
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
- Removal of existing sanitaryware
- Fitting of bath, shower, toilet, and basin
- Basic plumbing connections and testing
- Standard fitting of bathroom furniture and accessories
- General installation clean-up at the end of the job
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 new bathroom does not usually cut bills dramatically on its own, but efficient taps, showers, and toilets can help reduce water use. Long-term value often comes from improved reliability, better waterproofing, and less maintenance.

Frequently Asked Questions
How much does a new bathroom cost in the UK?
A full new bathroom often starts in the mid four figures and rises well into five figures if you choose premium fittings or make major layout changes.
Is it cheaper to keep the same bathroom layout?
Yes. Keeping the bath, shower, basin, and toilet in the same positions usually reduces plumbing and labour costs.
How long does a bathroom installation take?
Many full bathroom installations take around one working week, but more complex or higher-spec jobs can take longer.
Are tiles included in bathroom fitting quotes?
Sometimes, but not always. Some quotes separate out tiling, tile supply, or specialist finishing work, so it is worth checking carefully.
What usually adds most to the cost?
Layout changes, premium sanitaryware, extensive tiling, electrical work, and hidden floor or wall repairs are usually the main reasons budgets rise.
Should I get itemised quotes for a bathroom renovation?
Yes. Itemised quotes make it much easier to compare labour, suite costs, tiling, electrical work, and any exclusions like decorating.
