For most New Zealand homes, a full flooring installation takes anywhere from 2 to 7 working days, though this varies considerably depending on the type of flooring, the size of the home, subfloor condition, and how much furniture shifting or preparation is involved. A small two-bedroom unit getting new carpet could be done in a single day, while a larger home with hardwood timber floors and extensive subfloor prep might take the better part of two weeks.
What Affects the Timeline?
Several factors influence how long your flooring project will take:
- Floor type – Carpet is generally the fastest to install. Engineered timber, solid hardwood, and large-format tiles take longer due to acclimatisation, adhesive cure times, and more complex laying patterns.
- Home size – An average NZ home is roughly 150–200 m². Larger homes or open-plan layouts take more time, though open areas can actually be quicker per square metre than rooms with lots of corners and doorways.
- Subfloor condition – This is often the biggest wildcard. If your subfloor needs levelling, patching, or drying out, that can add 1–3 days before any flooring goes down.
- Acclimatisation – Solid and engineered timber boards need to sit in your home for 48–72 hours before installation so they adjust to your indoor humidity and temperature. This is especially important in NZ's varied climate, from humid Northland to cold Southland winters.
- Furniture and access – Rooms need to be cleared before work begins. If you're doing this yourself, factor in time to move everything out and back in.
- Adhesive and grout cure times – Glue-down vinyl and tiled floors need time to cure before foot traffic is safe. Tile grout typically needs 24–48 hours before walking on it.
Typical Timelines by Floor Type
| Floor Type | Average Install Time (150–200 m²) | Notes |
|---|---|---|
| Carpet | 1–2 days | Fast; underlay and stretching included |
| Luxury Vinyl Plank (LVP) | 1–3 days | Click-lock is quickest; glue-down takes longer |
| Engineered Timber | 2–4 days | Plus 48–72 hrs acclimatisation beforehand |
| Solid Hardwood | 3–5 days | May need sanding and finishing on-site |
| Ceramic/Porcelain Tile | 3–7 days | Includes setting, grouting, and cure time |
| Polished Concrete | 5–10+ days | Grinding, sealing, and curing stages |
Room-by-Room Breakdown
If you're only doing part of the house, here's a rough guide per room:
- Bedroom (12–15 m²): Half a day to one day for carpet or LVP
- Open-plan living/kitchen (40–60 m²): 1–2 days for LVP or engineered timber
- Bathroom or laundry (tiled): 1–2 days including waterproofing considerations
- Hallways and stairs: Stairs in particular are fiddly — allow extra time for carpet or timber on stairways
Subfloor Preparation: Don't Skip This Step
Subfloor prep is the foundation of any good flooring job and is often underestimated by homeowners. In New Zealand, many older homes have timber subfloors that may be uneven, springy, or affected by moisture — particularly in homes without adequate underfloor ventilation. Concrete slabs in newer homes may have moisture readings that are too high for direct glue-down installations.
A good installer will check moisture levels and flatness before laying anything. BRANZ provides guidance on acceptable subfloor conditions, and following manufacturer specifications is essential to maintain product warranties. Products from suppliers like Ardex or Mapei are commonly used for levelling compounds and adhesives in NZ.
Healthy Homes and Moisture Considerations
If you're a landlord, be aware that Tenancy Services Healthy Homes standards require adequate underfloor insulation and ground moisture barriers in rental properties. These requirements can affect what flooring systems are appropriate and may add time to a project if remediation is needed before new flooring goes in.
Do You Need a Building Consent?
In most cases, replacing like-for-like flooring in a residential home does not require a building consent under Schedule 1 of the Building Act. However, if you're making structural changes to the subfloor or altering a wet area (bathroom or laundry), consent may be required. Always check with your local council to confirm — rules can vary. See MBIE Building Performance for general guidance on what work requires consent.
When to Call a Professional
While keen DIYers can tackle some flooring types — particularly click-lock LVP in dry areas — most flooring work benefits enormously from professional installation. A qualified flooring installer will:
- Correctly assess and prepare the subfloor
- Ensure products are installed to manufacturer specs (protecting your warranty)
- Handle tricky areas like stairs, doorways, wet zones, and transitions between floor types
- Complete the job faster and with a better finish than most DIY attempts
Note that waterproofing in wet areas (bathrooms, laundry) must comply with the NZ Building Code (check with your council or MBIE Building Performance for the applicable clauses), and any associated plumbing work is restricted work that must be carried out by a licensed tradesperson registered with the Plumbers, Gasfitters and Drainlayers Board.
