Bathroom Renovation London – Professional Bathroom Refurbishment Services

A bathroom renovation in London can transform an outdated, damaged or poorly configured bathroom into a practical, modern space. Projects range from straightforward like-for-like replacements to complete refurbishments involving new plumbing, walk-in showers, wet rooms, tiling, electrical work, underfloor heating and redesigned layouts.

London bathroom renovation costs vary widely. Recent 2026 market guides generally place a mid-range full bathroom renovation around £8,000–£15,000, while simple refreshes can start from roughly £3,500–£5,000 and premium projects can exceed £20,000. The specification, layout and condition of the existing bathroom are major variables.

How Much Does a Bathroom Renovation Cost in London?

Bathroom prices vary significantly between a cosmetic update and a complete strip-out and rebuild.

Recent 2026 London guides indicate approximately:

These figures are broad market estimates rather than quotations. Different sources also include different combinations of sanitaryware, tiles and VAT, so quotations should be compared on a like-for-like basis.

What Affects Bathroom Renovation Cost?

The largest cost factors are usually:

• Bathroom size
• Existing condition
• Whether the layout changes
• Plumbing alterations
• Toilet position
• Tiling area
• Tile type and format
• Sanitaryware specification
• Shower system
• Waterproofing requirements
• Electrical alterations
• Underfloor heating
• Bespoke joinery
• Access and parking
• Waste removal

One of the most effective ways to control the budget is to retain the existing plumbing layout.

Moving a WC, basin, bath or shower can require new water and waste routes. One current London cost guide estimates that repositioning fixtures can add approximately £500–£1,500, depending on complexity.

Complete Bathroom Refurbishment

A complete bathroom refurbishment usually involves stripping the room back before rebuilding it.

A typical sequence is:

Survey → Strip-Out → First-Fix Plumbing → Electrical Work → Subfloor/Wall Preparation → Waterproofing → Tiling → Sanitaryware Installation → Second-Fix Electrics → Decorating → Sealing → Snagging

This provides an opportunity to address concealed defects rather than simply installing new finishes over existing problems.

Small Bathroom Renovation London

Small bathrooms are common throughout London flats and terraced properties.

A good design can maximise limited space using:

• Wall-hung vanity units
• Concealed cisterns
• Corner basins
• Walk-in showers
• Recessed storage
• Mirrored cabinets
• Large-format tiles
• Appropriate lighting

A small bathroom is not necessarily inexpensive to renovate. Plumbing, electrical work, waterproofing and trade attendance still carry substantial fixed costs even when the floor area is limited.

London Flat Bathroom Renovation

Renovating a bathroom in a London flat can require additional planning.

Before starting, consider:

• Lease restrictions
• Freeholder consent
• Management-company rules
• Working hours
• Communal-area protection
• Water isolation
• Waste removal
• Parking
• Shared soil stacks
• Properties below the bathroom

Moving plumbing in a flat can also be more difficult because access beneath the floor may be restricted.

Waterproofing and leak prevention are particularly important where another property is directly below.

Walk-In Shower Installation

Replacing a bath with a walk-in shower can create a more accessible and contemporary bathroom.

A typical installation may include:

• Shower tray or former
• Waterproofing
• Glass screen
• Thermostatic shower
• New drainage
• Wall tiling
• Floor tiling
• Shower niche
• Appropriate ventilation

Drainage position and floor construction should be assessed before choosing a very low-profile or level-access design.

Wet Room Installation London

A wet room removes the conventional shower enclosure or tray and incorporates the shower area into a waterproofed floor.

A proper wet-room installation requires particular attention to:

• Tanking
• Floor falls
• Drainage
• Subfloor stability
• Tile selection
• Slip resistance
• Ventilation

Current London estimates commonly put wet-room projects at around £10,000–£16,000, although larger or premium installations can cost substantially more.

Waterproofing is not an area where costs should be reduced simply to obtain the cheapest quotation.

Bath Replacement

A bathroom renovation can include replacing an old bath with:

• Straight bath
• Freestanding bath
• Shower bath
• Double-ended bath
• Compact bath

Keeping the replacement bath close to the existing plumbing arrangement will generally simplify installation.

Freestanding baths can require additional planning for taps, waste connections and floor loading depending on the product and property.

Toilet Replacement

Toilet options include:

• Close-coupled WC
• Back-to-wall WC
• Wall-hung WC
• Concealed-cistern WC
• Traditional-style WC

A like-for-like toilet replacement is generally much simpler than relocating the WC because moving the toilet can require significant alterations to the soil connection.

Bathroom Vanity Units

A vanity unit combines storage with the basin and can reduce bathroom clutter.

Options include:

• Floor-standing vanity
• Wall-mounted vanity
• Double vanity
• Bespoke cabinetry
• Integrated basin
• Countertop basin

Bespoke joinery can be particularly useful in awkward London bathrooms where standard furniture does not efficiently use the available space.

Bathroom Tiling

Tiling can represent a significant proportion of the renovation budget because both the material and installation are labour intensive.

Popular options include:

• Porcelain
• Ceramic
• Natural stone
• Marble-effect porcelain
• Mosaic
• Large-format tiles
• Patterned tiles

Tile installation costs can increase for intricate patterns, natural stone, large-format products
