Bathroom Renovation Costs in NZ

A bathroom renovation is one of the most popular home improvements in New Zealand — and one of the most frequently under-budgeted. Typical costs range from $8,000 for a basic refresh to $35,000+ for a full master ensuite rebuild.

What Drives the Cost?

  • Tiling — tiler rates run $80–$120/hr. Full-tile bathrooms (floor + all walls) add $3,000–$8,000 in labour alone
  • Waterproofing — mandatory under NZ Building Code E3. Budget $800–$1,500 for a standard bathroom
  • Plumbing — moving a toilet or shower drain is expensive ($1,500–$3,000 extra). Try to keep fixtures in existing locations
  • Fixtures quality — a Bunnings-spec toilet + vanity combo runs $1,500; a premium European set can hit $8,000+

Cost Ranges by Bathroom Type

Type Budget Mid High-end
Small bathroom (4m²) $8,000–$12,000 $14,000–$20,000 $22,000–$35,000
Medium bathroom (7m²) $12,000–$18,000 $20,000–$30,000 $32,000–$50,000
Master ensuite (12m²+) $18,000–$28,000 $30,000–$45,000 $45,000–$80,000+
