Bathroom renovation cost Birmingham — 2026 price guide

After installing bathrooms across every B postcode, the vast majority of full refurbishments fall into one of three honest brackets — all fully fitted, suite included, VAT included:

• Essential refurb: £4,500 – £7,500. Like-for-like layout, quality mid-range suite, full tiling.
• Mid-range install: £7,500 – £12,000. Walk-in shower, premium brassware, large-format tiles, vanity unit.
• Luxury / master ensuite: £12,000 – £20,000+. Bespoke design, frameless glass, feature tile walls, underfloor heating.

Two identical-sized bathrooms in Edgbaston and Erdington can land £3,000–£5,000 apart. The four factors that drive that gap:

• Property age — Victorian and Edwardian homes in Moseley, Harborne, Kings Heath often have lath-and-plaster walls and irregular joists that need additional prep.
• Layout changes — moving a soil stack in a terraced house adds £600–£1,500.
• Tile choice — basic ceramic at £25/m² vs large-format porcelain at £80/m² changes a 25m² job by over £1,300 in materials alone.
• Brassware — a budget thermostatic shower at £180 vs a designer concealed set at £950.

A real-world job from a 3-bed semi in Hall Green, 2.4m x 2.0m bathroom, mid-range spec:

• Strip-out, waste, skip: £450
• First & second-fix plumbing: £1,400
• Electrics (fan, downlights, certification): £380
• Boarding, tanking, plastering: £620
• Wall and floor tiling (porcelain, 20m²): £2,100
• Suite — bath, vanity, WC, basin, taps: £1,650
• Walk-in shower enclosure & thermostatic set: £980
• Final fit, silicone, snag, clean: £520
• Total: £8,100 fully fitted

Daily-rate billing is where Birmingham homeowners get burned. A job 'estimated' at £6,000 quietly becomes £9,000 because nobody agreed a fixed price up front. Every M3 Trades quote is itemised and fixed in writing before strip-out begins — the only price changes are if you change the spec, or if we find something inside a wall that genuinely wasn't visible at survey.
