Bathroom Renovation Cost by Type (2026)
Standard Family Bathroom Renovation
A full strip-out and refurbishment of an existing bathroom — replacing bath, shower, toilet and basin with a new suite, fully retiling walls and floor, and updating plumbing and electrics. The most common bathroom project in the UK. Cost is driven primarily by sanitaryware and tile specification rather than room size.
En-Suite Bathroom
En-suite projects fall into two categories: renovating an existing en-suite (like-for-like, same scope as a small bathroom), or creating a brand new en-suite from bedroom space. The latter involves partitioning, structural checks for floor loading, new soil pipe runs and a ventilation solution — significantly more complex and costly than a straightforward renovation.
Luxury Wet Room
A wet room is a fully waterproofed (tanked) shower room where water drains through a floor-level drain — no tray or enclosure. Requires specialist tanking of the entire floor and wet walls, careful drainage design and skilled tiling. The highest-cost bathroom type per m² due to the waterproofing complexity, but delivers a premium appearance and is ideal for accessible bathrooms.
Cloakroom / Downstairs WC
A cloakroom renovation — typically containing just a toilet and basin — is the most affordable bathroom project. The small size keeps materials and labour costs low. Creating a new cloakroom from scratch (e.g. under the stairs) involves new soil pipe routing and potentially structural work, which adds cost. Popular upgrade in family homes and adds genuine day-to-day convenience.
Worked Cost Examples (2026)
Full project budgets separating labour, sanitaryware, tiles and additional works — not a single blended figure.
Example 1: Mid-Range Standard Bathroom, 6m²
Same layout, like-for-like. London adds 15–25%.
Example 2: New En-Suite Created from Bedroom Space
New en-suite from scratch. Excludes building control fee (£300–£600). London adds 15–25%.
What Affects Bathroom Renovation Cost?
Bathroom quotes can vary dramatically for the same room. These are the six factors that account for most of the difference.
🚿 Sanitaryware specification
The single biggest variable. A budget suite (B&Q, Victorian Plumbing) costs £500–£1,000. A mid-range suite (Roca, Ideal Standard) £1,000–£2,500. A premium suite (Duravit, Villeroy & Boch, Laufen) £3,000–£8,000+. Always separate suite cost from labour when comparing quotes.
🪟 Tiles and flooring
Tile cost ranges from £15/m² (basic ceramic) to £150+/m² (large-format porcelain or natural stone). A standard bathroom uses 15–30m² of tiles. Underfloor heating adds £400–£1,200. The difference between budget and premium tiles alone can exceed £2,000.
💧 Wet room waterproofing
Wet rooms require full tanking of the floor and wet walls — typically adding £500–£1,500 over a standard shower enclosure. The tanking system must be done correctly: failed waterproofing causes structural water damage that costs far more to repair than the original saving. Only ever use fitters with proven wet room experience.
🏗 En-suite creation vs renovation
Renovating an existing en-suite is similar in cost to a small bathroom. Creating a new en-suite from bedroom space adds £2,000–£5,000 for partitioning, soil pipe routing and ventilation — on top of the bathroom fit itself. Factor this in early when budgeting a loft conversion or bedroom reconfiguration.
🔧 Services complexity
Moving the toilet (soil pipe relocation), adding a bath where there was only a shower, or changing from electric to thermostatic mixer shower all add plumbing complexity. Like-for-like position replacement is far cheaper than full reconfiguration. Always clarify layout changes upfront when requesting quotes.
📍 Location and access
London adds 15–25% to labour costs. Upper-floor bathrooms, narrow stairs, flats without goods lifts and restricted parking all increase material delivery time and labour. Unlike extensions or loft conversions, bathroom costs are relatively consistent across UK regions — spec matters more than postcode.
Bathroom Renovation Cost by Region (2026)
| Region | Relative cost | Standard bathroom (mid-spec) | Wet room (mid-spec) |
|---|---|---|---|
| London | Highest | £7,000 – £18,000 | £10,000 – £28,000 |
| South East & Home Counties | High | £6,000 – £16,000 | £8,500 – £24,000 |
| South West & Midlands | Medium | £5,000 – £13,000 | £7,000 – £20,000 |
| North of England | Medium-low | £4,500 – £12,000 | £6,500 – £18,000 |
| Scotland, Wales & NI | Medium-low | £4,000 – £11,000 | £6,000 – £17,000 |
Mid-specification ranges including mid-range sanitaryware, standard porcelain tiles, plumbing and electrics (like-for-like layout). Premium sanitaryware, natural stone tiles or full reconfiguration are additional.
How to Control Your Bathroom Budget
Bathroom renovations have fewer variables than kitchen projects, but the specification choices you make at the design stage determine 60–70% of the final cost. These decisions are worth making carefully before inviting fitters to quote.
Moving the soil stack, toilet position or waste runs adds £800–£2,500. Like-for-like replacement is by far the most cost-effective approach.
Tile cost varies 10x. Agree your tile choice before inviting quotes so fitters are pricing the same specification. Changing tiles after agreeing a price is a common source of disputes.
Supplying your own suite avoids the fitter's markup (typically 15–25% on goods). Order from an online retailer or bathroom showroom and ask your fitter to install it. Confirm they're comfortable with your chosen brands first.
Proper waterproofing behind tiles is non-negotiable. Failed tanking causes water ingress that damages joists, ceilings and neighbouring rooms — remedial costs far exceed the saving.
