A new bathroom ranges from £4,000 for a budget like-for-like swap to £45,000 for a luxury master suite with double shower, freestanding bath and stone tiling. This guide sets out the four typical tiers, where the budget actually goes (sanitaryware, tiling, plumbing, labour) and the items most often left out of cheap quotes.
| Project scope | From | To | Notes |
|---|---|---|---|
| Budget like-for-like (small bathroom) | £4,000 | £10,000 | Same layout, off-the-shelf suite |
| Mid-range full refit (family bathroom) | £8,000 | £18,000 | New layout, tile floor + walls |
| New en-suite (3–5 m²) | £6,000 | £14,000 | Shower + WC + basin |
| Walk-in / wet room | £9,000 | £22,000 | Tanking, drainage, glass |
| Premium suite (designer fittings) | £15,000 | £30,000 | Branded sanitaryware, stone tiles |
| Luxury master suite (bath + shower) | £22,000 | £45,000 | Freestanding bath, double shower |
Indicative ranges for London & South-East England, 2026. A site visit firms the figure to ±5%.
Bargain suite (B&Q, Wickes): £400–£900 for WC + basin + bath. Mid-range (Roper Rhodes, Bathstore): £1,200–£3,000. Premium (Duravit, Villeroy & Boch): £3,000–£8,000. Designer (Lefroy Brooks, Drummonds): £8,000–£25,000+.
Mixer shower with basic head: £80–£180. Thermostatic concealed: £180–£450. Dual-head with bar valve: £450–£900. Designer rain-head with separate handset (Hansgrohe, Grohe SmartActive): £900–£2,500.
Ceramic 600×300 (budget): £14–22/m². Porcelain 600×600 (mid): £28–45/m². Large-format porcelain (1200×600): £42–120/m². Natural stone (marble): £80–250/m². Tile labour is typically £45–70/m² on top.
Keeping the original layout is the cheap end — services already in place. Moving the WC, basin or shower position adds £600–£2,000 in new drainage runs, joist trimming and floor make-good.
A wet room (level-access tiled floor) needs full tanking, a fall to the gully, and a recessed drain — adding £1,500–£3,000 versus a standard shower tray. Worth it for accessibility and a high-end aesthetic.
A bathroom fitter (plumber-led) typically takes 6–10 days for a mid-range family bathroom, at £350–£500/day = £2,500–£5,000 in labour. Add tiling at £45–£70/m² (typically 20–35 m² in a family bathroom = £900–£2,400 in tiling labour). A premium or designer bathroom can run 15+ days of skilled labour.
A like-for-like bathroom replacement runs 1.5–2 weeks on site. A full refit with layout change runs 2.5–4 weeks. A wet room or premium suite is 3–5 weeks. Plan sanitaryware and tile procurement 4–8 weeks before site to avoid delays mid-build.
Designer sanitaryware and brassware easily double the budget for the same functional outcome. Stone or large-format tiles also add a multiplier on both supply and labour. Underfloor heating, motion sensor lighting, heated mirrors and demister pads each add £150–£400 — small numbers that stack up fast on a luxury suite.
A mid-range family bathroom is £8,000–£18,000 in 2026, including suite, brassware, tiles, plumbing and labour. A like-for-like swap can be done for £4,000–£10,000; a luxury master suite is £22,000–£45,000.
A new en-suite (3–5 m², shower + WC + basin) is £6,000–£14,000 in 2026, including plumbing run, drainage, tiling and a mid-range suite.
A walk-in wet room is £9,000–£22,000 depending on size and finish. The price premium over a standard shower tray bathroom comes from full tanking, falls in the floor screed and a recessed drain.
A like-for-like replacement runs 1.5–2 weeks. A full refit with layout change runs 2.5–4 weeks. A wet room or premium luxury suite is 3–5 weeks on site.
On a like-for-like bathroom, yes — buying direct from Victoria Plum, Soak.com or a local trade plumb-merchant saves the contractor markup. On a premium or designer bathroom, the showroom typically packages design + supply for a single fee.
