Bathroom Plumbers in Wellington

Common bathroom plumbing costs in New Zealand include toilet installation at $300 to $600 (labour only, toilet supplied separately), shower mixer replacement at $350 to $700, vanity and basin installation at $300 to $600, bath installation or replacement at $500 to $1,200, and heated towel rail connection at $200 to $400. A full bathroom plumbing rough-in for a new or renovated bathroom costs $3,000 to $6,000 depending on complexity and pipe runs.

Modern shower installations in New Zealand include tiled showers with a formed shower base or wet-floor design, acrylic shower units (liner and tray), and frameless glass shower screens. For tiled showers, proper waterproofing is essential — the membrane must extend at least 1,800mm up the wall in the shower area and across the entire floor. Your plumber will install the mixer valve, showerhead, and waste connection. Popular mixer brands in NZ include Methven, Felton, and Grohe.

Replacing a toilet in New Zealand is straightforward if you are using the same waste position. Standard close-coupled toilets cost $300 to $1,200 for the unit. Wall-hung toilets with concealed cisterns cost $800 to $2,500. When replacing a toilet, check whether your waste exits through the floor (S-trap) or through the wall (P-trap) and buy accordingly. WELS-rated dual-flush toilets use 4.5 and 3 litres per flush, saving significant water compared to older single-flush models.

All bathroom plumbing work in New Zealand must be done by a PGDB-registered plumber. Sanitary plumbing is restricted work — it is illegal to do your own plumbing work beyond minor maintenance like replacing a tap washer. Your plumber must ensure all work complies with the NZ Building Code and relevant standards including AS/NZS 3500. A certificate of compliance must be issued for new installations.
