South Auckland Bathroom Renovation Services
Four kinds of bathroom job we take on across South Auckland.

Full Bathroom Renovations
Full bathroom renovations in South Auckland take the room back to the framing and rebuild it with a waterproofing membrane, shower, vanity, toilet and ducted extractor.
Damp or rotten framing found behind the old linings is priced for your approval before it is replaced.
The site visit is free, and so is the written quote.

Rental Bathroom Renovations
Rental bathroom renovations for South Auckland landlords cover the ventilation the Healthy Homes standards require, along with hard-wearing fixtures and finishes.
New bathroom extractor fans must vent outside and have a 120 mm diameter or move at least 25 litres per second.
Tell us when the tenants are moving out, and the job is planned around the gap.

Family Bathrooms
Family bathrooms in large South Auckland households are planned for heavy daily use, with a bath and shower, a wide vanity and plenty of storage.
In Māngere West, households averaged 4.7 people at the 2023 Census.
Tell us how many people use the bathroom each morning.

Separate Toilets and Second Bathrooms
Separate toilets and second bathrooms take pressure off the main bathroom in a busy house.
Renovating the toilet with the bathroom shares the plumber and tiler on one quote.
A new toilet or bathroom in a different spot needs new drainage, which Nick checks at the site visit.

How South Auckland jobs are priced
What Sets the Cost of a South Auckland Bathroom
Each South Auckland bathroom is priced in writing after a free site visit. Landlords get a quote that shows the ventilation work separately, so it is clear what the Healthy Homes item costs.
Damp framing
Rotten framing or flooring behind an old shower adds framing work before the rebuild.
Ventilation
A new duct to open air costs more than reusing an existing vent.
Bath and shower
Keeping a bath and adding a tiled shower adds waterproofing and a consent.
Layout changes
Moving the toilet or shower means new drainage.
Fixtures and finishes
Hard-wearing mid-range fittings keep a rental or family bathroom at the lower end.

What the census says about South Auckland homes
Damp Homes, Rentals and Healthy Homes in South Auckland
Māngere-Ōtāhuhu reported the highest share of damp homes of any mainland Auckland local board at the 2023 Census, at 32.6%. Ōtara-Papatoetoe followed at 30.1% and Manurewa at 26.8%. In Franklin, further south, the figure was 13.8%.
Home ownership is lower here too. At the 2023 Census, 40.8% of Māngere-Ōtāhuhu households owned their home or held it in a family trust, and 41.7% in Ōtara-Papatoetoe. Papakura grew faster than any other mainland local board, up 25.5% between 2018 and 2023.
The Healthy Homes ventilation standard requires rental bathrooms with a shower or bath to have an extractor fan that vents outside. Fans installed since 1 July 2019 must have a diameter of at least 120 mm or an exhaust capacity of at least 25 litres per second. Every extractor Alchemy fits is ducted outside.
