A new bathroom can transform both the look and feel of your home. Whether you're updating a family bathroom, redesigning an ensuite or creating a relaxing, spa-inspired space, understanding what your budget can achieve is an important place to start.
With so many styles, materials and suppliers to choose from, bathroom costs can vary considerably.
In this guide, we explore typical bathroom renovation costs in the UK, what influences the price and how to make informed decisions before choosing a supplier.
How much does a new bathroom cost in the UK?
The cost of a new bathroom depends on the size of the room, the quality of the fittings, the materials selected and the complexity of the installation.
According to Checkatrade's 2026 bathroom cost guide, the average cost of a new bathroom in the UK is approximately £7,000, with larger or more complex renovations costing £14,000 or more.
For homeowners planning a professionally designed and installed bathroom, the following indicative budgets provide a useful starting point:
| Bathroom type | Indicative budget |
|---|---|
| Quality bathroom renovation | £8,000–£15,000 |
| Design-led bathroom renovation | £15,000–£30,000 |
| Bespoke bathroom renovation | £30,000–£50,000+ |
These are illustrative planning ranges, not national averages. They assume bathroom fittings, surfaces and installation, but exclude significant structural alterations.
A beautiful bathroom doesn't necessarily require the largest budget. Good design, carefully selected materials and the right supplier can make all the difference.

What affects the cost of a new bathroom?
1. Bathroom fittings and sanitaryware
Baths, showers, basins and toilets can vary significantly in price depending on their design, materials and manufacturer.
A simple, well-designed bathroom suite can create a beautiful result, while features such as freestanding baths, walk-in showers and specialist brassware may increase the overall cost.
It's worth considering which features will make the greatest difference to how you use the space.
For example, a generous walk-in shower may be more valuable to you than a freestanding bath, particularly in an ensuite.
2. Tiles and materials
Your choice of wall and floor finishes can have a considerable impact on your bathroom budget.
Porcelain and ceramic tiles offer a wide range of colours, textures and finishes, while natural stone such as marble and limestone can create a more individual look.
Large-format tiles, specialist patterns and extensive floor-to-ceiling tiling may increase installation costs.
Materials should be chosen for practicality as well as appearance, particularly in wet areas.

3. Showers and bathing
The shower or bath is often a focal point of the bathroom.
Walk-in showers, wet rooms, rainfall showerheads and freestanding baths can all create a distinctive feel, but costs depend on the products and installation requirements.
Waterproofing, drainage and water pressure are particularly important considerations when planning a shower.

A well-planned shower can improve both the appearance and everyday usability of the space.
4. Layout and installation
Retaining your existing bathroom layout can help control costs, particularly when plumbing and drainage remain in the same locations.
Moving a toilet, relocating a shower or changing the configuration of the room may require additional plumbing and building work.
According to Checkatrade's 2026 bathroom fitter cost guide, bathroom fitters typically charge £320–£480 per day, although costs vary by location and the complexity of the work.

Installation is an important consideration when comparing bathroom quotations, particularly where specialist tiling, electrical work or waterproofing is involved.
5. Storage and finishing details
Thoughtful storage and carefully selected finishing details can make a bathroom feel both practical and beautifully considered.
Vanity units, recessed shelving, illuminated mirrors, heated towel rails and discreet lighting can all improve the space.
Bespoke joinery offers greater flexibility, although many established bathroom suppliers also provide attractive fitted storage solutions.
These details are worth considering early, particularly when space is limited.
Where should you spend and where can you save?
A successful bathroom renovation is about making considered choices and investing in the elements that matter most to you.
Worth investing in
- Professional waterproofing and installation.
- Quality taps, showers and fittings used every day.
- Durable, easy-to-maintain surfaces.
- A practical layout with sufficient storage.
- Good lighting and ventilation.
Where you might be more selective
- Expensive natural stone where quality porcelain could achieve a similar look.
- Bespoke storage where standard vanity units work equally well.
- Specialist finishes that add cost without improving functionality.
- Relocating plumbing unnecessarily.
- Features that are unlikely to be used regularly.
A good bathroom designer should help you balance appearance, practicality and budget.
What costs should you allow for beyond the bathroom itself?
Before committing to a bathroom renovation, it's important to understand exactly what's included in your supplier's quotation.
Additional costs might include:
- Removal and disposal of the existing bathroom.
- Plumbing and drainage alterations.
- Electrical work and lighting.
- Waterproofing and preparation of walls and floors.
- Underfloor heating.
- Ventilation improvements.
- Decorating and finishing.
- Structural repairs or alterations.
Some suppliers offer a complete design and installation service, while others focus on products and design, leaving you to arrange trades separately.
Older properties may also reveal unexpected issues once work begins, so allowing a contingency is sensible.
Always compare quotations on a like-for-like basis.
How do you choose the right bathroom supplier?
Finding the right bathroom supplier involves more than choosing fittings you like.
Some companies specialise in contemporary bathrooms, while others focus on traditional designs, bespoke furniture, natural materials or complete renovation services.
Before approaching suppliers, it helps to consider:
- Your preferred style and finishes.
- The size and layout of your bathroom.
- Your overall budget.
- Whether you want a bath, shower or both.
- Your storage requirements.
- Your ideal project timescale.
A clear brief makes it easier to identify suitable suppliers and compare their proposals.
