Factors affecting cost in the UK

  • ·Region — London adds 20–30% over national pricing.
  • ·Bath vs walk-in shower — shower-only setups are cheaper to fit and tile.
  • ·Tile size — large-format tiles in small rooms need more cutting and waste.
  • ·Layout changes — moving the toilet adds £400–£1,000.
  • ·Ventilation — adding ducted extraction in flats can add £200–£500.

Hidden & unexpected costs

  • ·Rotten joists or floorboards under the bath, discovered after strip-out.
  • ·Replacing soil pipe boxing with tiled stud walls.
  • ·Asbestos in older Artex ceilings (£50–£200 testing).
  • ·Repainting hallway walls scuffed during access.
  • ·Building Control sign-off for new ventilation in internal rooms.

Ways to reduce cost

  • ·Keep the existing layout to avoid moving soil pipes and waste runs.
  • ·Choose a shower over a bath if you don't need to bathe children — saves on suite and tiling.
  • ·Buy the suite from a trade merchant such as Wickes or City Plumbing for trade pricing.
  • ·Use ceramic tiles up to 600 × 300 mm — easy to cut, fast to fix.
  • ·Bundle a plumber and tiler on a fixed quote rather than separate trades.

Frequently asked questions

How long does a small bathroom refit take?
Typically 5–9 working days from strip-out to final decoration in a 3–5 m² room.
Is a small bathroom cheaper per m² than a large one?
No — labour per m² is usually higher because access is tight and fixed costs like skip hire and travel don't shrink.
Can I keep the existing bath to save money?
Yes, refurbishing an existing cast-iron bath costs £200–£500 vs £400+ for a new suite item, and avoids re-tiling the surround.
Do I need an electrician for a small bathroom?
Yes, any electrical work in a bathroom must be carried out by a Part P registered electrician and notified to Building Control.
Will VAT be charged?
Yes, 20% VAT applies on labour and materials from VAT-registered contractors.
Can I DIY a small bathroom?
Tiling and decorating can be DIY. Plumbing connections, gas and electrics should be done by qualified trades to comply with regulations and protect insurance.
