How Much Does a Bathroom Renovation Cost in Bromley in 2026?
Updated: Aug 28
If you’re planning a new bathroom or a complete bathroom renovation in Bromley, one of the first questions you’ll probably ask is:
Written by the team at The Bathroom Project — hands-on bathroom, plumbing and heating specialists serving Bromley, Orpington and across Kent.
“How much should I actually expect to pay?”
The honest answer is that bathroom renovation prices vary considerably.
A straightforward replacement bathroom with the existing layout can cost considerably less than a fully redesigned, high-specification bathroom involving new plumbing, complex tiling, bespoke furniture, premium sanitaryware or a walk-in wet-room style shower.
For a properly planned and professionally installed bathroom renovation in Bromley, we would generally recommend allowing around £10,000–£18,000 as a realistic starting range for a quality full renovation, with more complex or highly specified projects potentially exceeding £20,000.
The right budget depends on what you want to achieve, rather than simply the size of the room.
Quick answer: how much does a bathroom renovation cost in Bromley?
As a broad planning guide:
Project type
Typical planning budget
Smaller bathroom / straightforward renovation
£8,000–£12,000
Standard family bathroom
£10,000–£16,000
Premium bathroom renovation
£15,000–£20,000+
Large or complex bathroom
£18,000–£25,000+
These are planning ranges rather than fixed prices. Every bathroom is different, and the final quotation depends on the existing room, specification, layout, materials and amount of work required.
National 2026 cost guides show a very wide range, with standard full renovations often quoted below the figures above, while London and South-East projects and premium installations can be substantially higher. (Checkatrade)
Why do bathroom renovation prices vary so much?
Two bathrooms can be almost identical in size but have completely different project costs.
The biggest factors are usually:
The condition of the existing bathroom
Whether the layout is staying or changing
Plumbing and drainage alterations
Electrical requirements
Waterproofing
Amount and type of tiling
Sanitaryware
Bathroom furniture
Shower specification
Brassware
Heating and underfloor heating
Lighting
Ventilation
Glass and shower enclosures
Preparation and remedial work
The complexity of installation
The quality of the materials selected
This is why comparing bathroom quotations purely on the final number can be misleading.
A £10,000 quotation and a £15,000 quotation may not actually be offering the same bathroom.
What does a full bathroom renovation normally include?
A properly managed bathroom renovation can involve considerably more than removing the old suite and installing a new one.
Depending on the project, the work can include:
Design and planning
Before work begins, the layout, products, finishes and practical requirements need to be considered.
Good planning can prevent expensive mistakes later.
Strip-out and preparation
The existing bathroom may need to be removed, including:
Existing sanitaryware
Old flooring
Wall finishes
Old shower enclosure
Existing furniture
Redundant pipework
The room then needs to be properly assessed before installation begins.
Plumbing
This may include new hot and cold-water pipework, waste connections and repositioning of fixtures.
Keeping the existing layout can reduce costs, while moving the toilet, shower or basin can introduce additional plumbing and preparation work.
Electrical work
Modern bathrooms can require lighting, illuminated mirrors, extractor fans, heated towel rails, underfloor heating and other electrical installations.
All electrical work should be completed appropriately for the bathroom environment and applicable regulations.
Waterproofing
Areas exposed to significant water need appropriate preparation and waterproofing.
This is particularly important around showers and wet-room installations.
It isn’t an area where we recommend cutting corners simply to reduce the quotation.
Tiling and wall finishes
Your choice of tiles can have a significant impact on the final cost.
Large-format porcelain, natural stone, intricate patterns and detailed layouts generally require more preparation and skilled installation than straightforward ceramic tiling.
Sanitaryware and furniture
The choice of toilet, basin, vanity unit, bath, shower and storage can range from relatively straightforward products to premium and bespoke options.
Final installation and finishing
The final stage brings everything together:
Sanitaryware
Brassware
Shower systems
Glass
Furniture
Mirrors
Lighting
Heating
Accessories
Sealants and finishing details
The quality of the installation matters just as much as the products you choose.
Does keeping the same layout save money?
Usually, yes.
Keeping the toilet, basin, bath and shower in broadly the same positions can reduce the amount of new plumbing and drainage work required.
However, this doesn’t automatically mean keeping the existing layout is the best option.
Sometimes changing the layout can dramatically improve:
Storage
Shower space
Accessibility
Natural movement through the room
Visual balance
Overall appearance
The question should therefore be:
“Is changing the layout worth the additional investment?”
rather than simply:
“How much can I save by not moving anything?”
What makes a bathroom renovation more expensive?
There are several features that can quickly move a project into a higher budget.
Moving plumbing
Relocating toilets, showers and baths can require additional pipework, drainage and floor preparation.
Walk-in showers and wet-room designs
These can involve additional waterproofing, drainage, floor gradients, glass and specialist preparation.
Large-format tiles
Large porcelain tiles can look fantastic but require careful preparation, handling and installation.
Premium brassware
Taps and shower systems vary enormously in price and specification.
Bespoke furniture
Made-to-measure storage can transform a bathroom but costs more than standard off-the-shelf furniture.
Underfloor heating
This can add comfort and luxury but requires additional installation and control equipment.
Difficult existing conditions
Older properties can uncover problems such as damaged flooring, poor previous installations, inadequate pipework or water damage.
This is one reason it is difficult to provide an accurate bathroom renovation price without seeing the room.
Why is a £10,000 bathroom different from a £15,000 bathroom?
It isn’t necessarily about making the room “look £5,000 better”.
The additional investment can go into:
Better sanitaryware
Better brassware
Higher-quality furniture
Larger or more complex tiles
Better shower systems
Improved lighting
Underfloor heating
Bespoke storage
Better glass
More involved layout changes
Higher levels of preparation
More complex installation
The important thing is that the budget should be allocated to the things that matter most to you.
Should I spend more on the products or the installation?
Both matter.
A beautiful £4,000 bathroom suite won’t perform properly if it has been poorly installed.
Likewise, paying for an excellent installation while selecting unsuitable or poor-quality products can create problems later.
We believe a successful bathroom project combines:
Good design + appropriate products + skilled installation + proper preparation.
What should I ask a bathroom company before accepting a quote?
Before choosing a contractor, ask:
What exactly is included?
Are the sanitaryware and materials included?
Is waste removal included?
Is preparation included?
Is waterproofing included where required?
Are electrical works included?
Are plumbing alterations included?
Are all tiling and finishing works included?
Who is responsible for supplying the products?
What happens if an issue is discovered once the old bathroom is removed?
How long is the project expected to take?
Who will actually carry out the work?
Is the project managed from start to finish?
A detailed quotation makes it much easier to compare different bathroom companies fairly.

Is a bathroom renovation worth the investment?
A well-designed bathroom can improve both the enjoyment and functionality of your home.
But the best bathroom isn’t necessarily the most expensive one.
The aim should be to spend your money intelligently on the elements that make the biggest difference to the room.
That might mean investing in an excellent shower rather than an expensive bath.
Or better storage rather than expensive decorative features.
Or improving the layout rather than simply replacing everything in its existing position.
