Bathroom Renovations for Mount Roskill Landlords and Families
Four kinds of bathroom work cover most Mount Roskill houses, from a single rental bathroom to a second bathroom for a large household.
Rental
Rental Bathrooms Built to Last
Landlords need a bathroom that copes with a run of tenants. We fit large-format tiles with fewer grout lines, a wall-hung vanity that is easy to clean under, and a fan ducted outside that meets the Healthy Homes ventilation standard. Give Nick your tenancy dates and he will plan the work around them.
Second bathroom
Adding a Second Bathroom
One in three Mount Roskill homes has four or more bedrooms, and one in ten has five or more. Large households soon outgrow a single bathroom. Where there is space, we turn a spare room, a laundry corner or a large wardrobe into a second bathroom or an ensuite, with its own drainage and ventilation. Read about our ensuite renovations for bigger family homes.
Family bathroom
Family Bathroom Rebuilds
In a family house the main bathroom works hardest. We keep the bath if you need it for young children, add a separate shower where the room allows, and choose a vanity with drawers deep enough for a whole household's bottles.
Toilet and laundry
Toilets and Laundries Next Door
If the toilet or the laundry sits next to the bathroom, we renovate it on the same programme. One strip-out and one set of trades costs less than doing the rooms a year apart.
Mount Roskill bathroom prices
Bathroom Renovation Prices in Mount Roskill
These three bands come from our Auckland pricing. Nick confirms the figure for your bathroom in writing after the site visit.
$15,000 to $28,000
Rental or small bathroom, existing layout
$22,000 to $40,000
Whole family bathroom rebuilt
$40,000 to $65,000+
Larger bathroom or premium finishes
A second bathroom built into existing space costs more than a renovation, because it needs new drainage, a new water supply and a fan run to the outside. Nick prices it as its own line, so you can compare it with renovating the main bathroom alone.
What changes the price
Five Price Drivers for Mount Roskill Bathrooms
Five decisions move a Mount Roskill bathroom quote up or down.
Number of bathrooms
Renovating two bathrooms on one programme shares the strip-out and the trades.
New drainage
A bathroom in a new position needs a new waste run, which a renovation in place avoids.
Ventilation
Ducting a fan through a roof space is quicker than through a wall with no ceiling access.
Tiles
Large-format tiles cover a wall faster and leave fewer grout lines to clean.
Tenancy timing
Working between tenancies keeps the job to one block of time, with no tenant in the house.

A Clawfoot Bath and Walk-In Shower in Mount Eden
Mount Eden is a few minutes north of Mount Roskill, and our job there rebuilt the bathroom of an older character home. A white clawfoot bath sits under a sash window, beside a walk-in shower with a black rail shower and a fixed glass panel.
Grey stone-look tiles run to waist height around the room, and white tiles run full height in the shower and behind the vanity. The Mount Eden clawfoot bath bathroom page has the full set of photos and a short video.
Mount Roskill at the 2023 Census
Damp and Mould in Mount Roskill Homes
The ten Mount Roskill census areas held 29,100 residents in 9,024 occupied homes at the 2023 Census.
25.5%
of Mount Roskill homes were damp, rising to 36.6% in Mount Roskill North East
22.4%
of homes had mould larger than an A4 sheet
49.4%
of households did not own their home
A quarter of homes reporting damp is a high figure, and bathrooms are part of the cause. Steam from a daily shower soaks into old plasterboard and timber when the fan is weak or missing.
Building Code clause E3 requires bathrooms to guard against moisture build-up and to have surfaces that are impervious and easy to clean. We meet that with a waterproofing membrane under every tiled wet area, tiled or sealed linings, and a fan vented outside close to the shower.

The most trustworthy and dependable bathroom renovation contractors I have ever worked with are without a doubt Nick and his crew. They are punctual, economical, and reliable in fulfilling commitments. They went above and beyond by offering additional recommendations on how to improve the renovation's worth. I'm grateful. I'm always pleased to write a sincere evaluation for their work that is truly excellent.
