Luxury bathroom renovation by Kallums Bathrooms in Putney, South West London

Planning a bathroom renovation in Putney? Understanding the average cost of a new bathroom is the essential first step and the figures vary significantly depending on whether you’re looking for supply only, a design-led project or a fully managed renovation from start to finish.

At Kallums Bathrooms, we’ve guided hundreds of homeowners through their projects and this guide gives you a clear, honest breakdown of what to expect at each level of investment.

Supplying Your Bathroom

If you already have an installer in place and are looking for premium bathroom products, our supply-only service may be the perfect fit.

We partner with some of the industry’s most respected manufacturers, selecting products that deliver exceptional quality, performance and style. From statement brassware to beautifully crafted furniture and luxurious bathing solutions, every product is chosen with longevity and everyday enjoyment in mind.

Every bathroom is unique, so these figures are intended as a helpful guide rather than a fixed cost. Your final investment will be shaped by the size of the space, the products you choose and the overall specification of your project.

Typical Product Investment

  • Full bathroom: £5,000–£10,000
  • Cloakroom or downstairs WC: £2,000–£5,000

Bathroom Design & Supply

The most successful bathrooms combine beautiful products, intelligent layouts and expert design.

Our Bathroom Design & Supply service is designed to help you bring your vision to life with confidence. The process includes consultations, site surveys, mood boards, CAD drawings, elevations and realistic 3D visuals, allowing you to explore every detail before making any final decisions.

Our bathroom design service is charged at £400, however this fee is fully credited against your bathroom order. In practice, this means your design is effectively included when you choose Kallums Bathrooms to supply your products.

Prices shown are estimates to give you a general guide, every bathroom is different and your final investment will depend on the size of the space, the products chosen and the level of service required.

Typical Investment

  • Full bathroom: £5,000–£10,000
  • Cloakroom or downstairs WC: £2,000–£5,000


This service gives you the reassurance that every element has been carefully planned before your project moves forward, helping to create a bathroom that is both beautiful and practical.

Fully Managed Bathroom Renovation

For homeowners looking for a truly seamless experience, our fully managed bathroom renovation service brings every stage of the project together under one roof.

From the initial design consultation through to installation and completion, our experienced team manages the entire journey. Unlike retailers who hand you off to separate installers, we coordinate every trade, every detail and every stage of the renovation process.

With dedicated project management and skilled in-house installation teams, you can enjoy the confidence that your bathroom is being delivered to the highest standards from start to finish.

Complete Project Investment

  • Fully managed bathroom renovation: £15,000–£20,000


This typically includes bathroom design, product supply, installation and dedicated project management.

The final cost of a bathroom renovation in Putney will vary depending on the size of the room, the products selected, tiling requirements, bespoke features and any structural or layout changes required.

What Influences the Cost of a New Bathroom?

No two bathroom renovations are exactly the same, which is why costs can vary significantly from one project to another.

Some of the key factors that influence the overall investment include:

  • The size of the room
  • Product specification and finishes
  • Tiling materials and coverage
  • Bespoke furniture and storage solutions
  • Plumbing or electrical alterations
  • Structural changes to the layout
  • Specialist installation requirements


While it can be tempting to focus solely on the initial cost, the quality of the products selected, the expertise behind the design and the standard of installation all play an important role in the finished result.

A well-executed bathroom renovation not only enhances your home today but continues to deliver comfort, functionality and enjoyment for years to come.

If you’re renovating more than one bathroom, there are real advantages to tackling them at the same time.
