Average Bathroom Renovation Costs in London (2026)
Bathroom renovation costs in London are generally higher than the UK average due to labour rates, access challenges, and stricter compliance requirements. Based on current market trends, most homeowners can expect the following price ranges:
Small bathroom or en-suite: £7,500 - £12,000
Standard family bathroom: £12,000 - £18,000
Large or premium bathroom: £18,000 - £30,000+
These figures typically include labour, standard fixtures, tiling, plumbing, electrics, and basic finishing. Luxury materials, layout changes, or structural alterations increase the final cost.
Bathroom Renovation Cost Breakdown
It’s helpful when you know where every pound is spent. A typical London bathroom renovation budget is usually split across these areas:
Labour
Labour makes up the largest portion of the budget. In London, experienced ones take higher rates due to demand and certification requirements. A bathroom renovation involves plumbers, electricians, tilers, and general builders working together.
Fixtures and Fittings
This includes toilets, basins, baths, showers, taps, and vanity units. Prices vary greatly depending on brand and quality, with mid-range options offering the best balance between durability and cost.
Tiling and Waterproofing
Wall and floor tiling, tanking, and waterproof membranes are essential in UK bathrooms. Poor waterproofing leads to costly repairs later, so this is not an area to cut corners.
Plumbing and Electrical Work
Moving pipework, upgrading electrics, or installing underfloor heating increases costs but can significantly improve functionality and comfort.
Waste Removal and Site Management
Old fixtures, tiles, and materials must be removed safely, which is particularly important in flats or terraced homes with limited access.
Budget vs Mid-Range vs Premium Bathroom Renovations
Let’s see what different budget levels usually cover:
Budget Renovation
Standard fittings and tiles
Minimal layout changes
Best for rental properties or quick upgrades
Mid-Range Renovation
This is the most popular option for homeowners. It includes:
Updated layout
Quality tiles and fittings
Walk-in or combined bath/shower
Improved lighting and ventilation
Most of the queries related to how much does it cost to renovate a bathroom in London come from this range, due to differences in good design and materials.
Premium Renovation
Modern quality design
High-end finishes
Underfloor heating
Smart bathroom features
Ideal for long-term homes or high-value properties
Factors That Affect Bathroom Renovation Costs
Several factors can push costs up or down:
Larger spaces require more materials and labour.
Moving toilets, baths, or showers increases plumbing work.
Victorian and Edwardian homes often need pipework or wiring upgrades.
Flats or terraced houses may require additional time for material handling.
Tiles and fittings range from affordable to luxury.
Labour Costs in London
London labour rates are typically 15-30% higher than the UK average. This reflects the cost of living, demand for skilled trades, and the need for certified professionals.
UK Regulations That Impact Bathroom Renovation Costs
Bathroom renovations in London must comply with several UK regulations:
Electrical safety (Part P): Electrical work must be certified.
Water efficiency (Part G): New fittings must meet water usage standards.
Ventilation requirements: Proper extraction is needed to prevent damp and mould.
Homes in conservation areas or listed buildings may require additional approvals, which can affect timelines and budgets.
How Long Does a Bathroom Renovation Take?
A standard bathroom renovation usually takes 10-15 working days once work begins. More complex projects involving layout changes or structural work may take 3-6 weeks. Delays often occur due to material lead times or uncovering hidden issues behind walls or floors.
Hidden Costs to Plan For
Even with careful planning, some costs only become clear once work starts:
Old or damaged pipework
Damp or water damage
Floor levelling
Upgrading ventilation systems
Allowing a 10-15% margin in your budget is a sensible approach.
Does Renovating a Bathroom Add Value?
In London, a well-designed bathroom can add 5-10% to a property’s value. Mid-range renovations tend to offer the best return, whilst overly luxurious finishes may not always be reflected in resale price.
