Bathroom Renovation Builders in Wellington

Bathroom renovations in New Zealand typically cost $15,000 to $40,000 for a standard bathroom and $25,000 to $55,000 for a high-end remodel. A basic refresh (new fixtures, paint, and flooring) costs $8,000 to $15,000. A full gut-and-remodel including moving plumbing, new waterproofing, tiling, vanity, toilet, and shower costs $20,000 to $35,000. An ensuite addition to an existing bedroom costs $25,000 to $45,000 depending on proximity to existing plumbing.

New Zealand Building Code clause E3 requires that all wet areas (showers, baths, and floors in bathrooms) are properly waterproofed to prevent moisture damage. Waterproofing must be done by a licensed tradesperson and is considered restricted building work. The most common system uses a liquid-applied membrane over tile backing board. Incorrect waterproofing is one of the leading causes of leaky building claims in New Zealand, so this is not an area to cut costs.

A full bathroom renovation typically includes demolition of existing fittings and surfaces, plumbing rough-in (moving or replacing pipes), electrical work (lighting, heated towel rails, ventilation), waterproofing of wet areas, tiling of floors and walls, installation of vanity, toilet, shower, and bath, painting, and final plumbing and electrical fit-off. A good bathroom builder coordinates all the subcontractors — plumber, electrician, tiler, and painter — so you deal with one point of contact.

When selecting fixtures for your bathroom renovation, look for products with a WELS (Water Efficiency Labelling Scheme) rating for water savings. A 3-star rated showerhead uses 7 to 9 litres per minute compared to 15 to 25 litres for older models. Popular fixture suppliers in New Zealand include Methven, Mico Bathrooms, Plumbing World, and Tile Warehouse. Consider a wall-hung toilet and floating vanity for a modern look that also makes floor cleaning easier.
