New bathroom cost - Understanding prices in the UK

A simple guide to the cost of renovating your bathroom in the UK in 2025. Let’s get started.

Average cost of a new bathroom in the UK

A premium bathroom renovation in the UK typically ranges from £5,000 to £8,000. This investment covers a complete transformation, tailored to your unique vision and space.

Key factors influencing the final price include:

  • Bathroom dimensions

  • Quality of chosen fixtures and fittings

  • Extent of required work

  • Your location within the UK

Here's a glimpse at the costs for premium bathroom elements:

A plumber will typically charge between £1,500 and £3,000. A standard bathroom installation usually takes 5-10 days.

Factors affecting new bathroom costs

When crafting your dream bathroom, several key elements influence the overall investment:

Spatial design and layout

The dimensions and configuration of your bathroom play a crucial role. Larger spaces offer more possibilities for luxurious features but require additional materials and craftsmanship. Unique layouts or architectural features can inspire bespoke solutions, enhancing the overall design.

Premium fixtures and fittings

The quality and exclusivity of your chosen bathroom elements significantly impact the final cost. Opting for designer brands and bespoke items, such as rainfall showers or custom-made vanities, elevates both the aesthetics and the investment.

Plumbing considerations

Reimagining your bathroom's layout may involve relocating key features like toilets or showers. While this allows for innovative designs, it does require more extensive plumbing work, which influences the overall cost.

Premium surfaces

Your choice of tiling and flooring materials can transform the space. From rare marbles to handcrafted tiles, these elements contribute significantly to the bathroom's ambiance and overall cost.

Luxurious additions

Incorporating indulgent features like underfloor heating, towel warmers, or built-in audio systems enhances comfort and sophistication, while also affecting the final investment.

Cost comparison - Full renovation vs refresh

Complete bathroom transformation

A full luxury renovation typically requires an investment of £5,000 to £8,000. This comprehensive approach includes:

  • Carefully removing existing elements

  • Bespoke plumbing and electrical solutions

  • Premium flooring and wall treatments

  • High-end bathroom suite (designer toilet, vanity, bath/shower)

  • Expert fitting services from multiple specialists

A simple refresh 

A bathroom refresh to modernise or update concentrates on elevating key elements while preserving some existing features. Investments can range from £1,000 to £3,000 and may include:

  • Installing a statement bathtub or custom shower enclosure

  • Upgrading to designer taps and fixtures

  • Adding a bespoke vanity unit

  • Refreshing wall finishes

  • Enhancing specific areas with luxury tiling

Considerations for your decision

Several factors influence whether a complete transformation or focused enhancement aligns best with your vision:

  • Current state of plumbing and electrical systems

  • Desired level of customisation and luxury

  • Extent of layout changes envisioned

While a focused enhancement offers a more immediate refresh, a complete transformation provides the opportunity to fully reimagine your space, ensuring every detail aligns with your luxury vision.
