What Affects Cost?

  • Waterproofing: Essential in bathrooms. Tanking cost: £300-800+
  • Ventilation: Proper extraction fan required (adds £150-300)
  • Substrate prep: Damp, tiling damaged, needs substrate replacement (adds £500-1,500)
  • Layout changes: Moving toilet/basin to new location (adds £800-2,000)
  • Heated floor: Underfloor heating adds £500-1,500 to project

Common Misunderstandings

  • "All tiles are the same cost": Budget vs premium: 4-5x price difference
  • "Bathroom takes 3 days to fit": Professional bathroom takes 6-8 days minimum
  • "Grout is included in tile cost": No—waterproofing and grout separate costs
  • "We can skimp on waterproofing": Terrible idea—damp in bathrooms is catastrophic

Red Flags

  • Quote doesn't mention waterproofing/tanking
  • No detail on fixture brands/specifications
  • Doesn't assess existing substrate condition
  • Unrealistic timeframe (says 3 days for complete family bathroom)
