Shower installation cost in NZ: tiled, acrylic, or a new shower
Shower installation in New Zealand costs $900–2,000 for an acrylic shower unit and $1,550–8,250 for a new tiled shower, or $2,000–9,500 in Auckland (Superior Renovations; the page does not state GST status). Replacing one in the same place, without adding a fixture, is normally exempt from building consent. Whatever the finish, the membrane behind it is the part that matters.
| Option | Cost | Notes |
|---|---|---|
| Acrylic shower unit, installed | $900–$2,000 | Superior: budget-friendly, low maintenance, quick install, well suited to rentals. |
| New tiled shower, New Zealand range | $1,550–$8,250 | Superior puts the Auckland range higher, at $2,000–9,500, on labour rates and membrane products. |
| New tiled shower, Auckland | $2,000–$9,500 | Superior attributes the gap to Auckland labour rates and membrane product costs. |
| Retiling an existing shower, plumbing left where it is | $1,800–$4,000 | Superior states this figure excludes waterproofing. |
Superior Renovations does not state a GST status on its page, so none of these figures is adjusted. The retile-only figure explicitly excludes waterproofing, so it is not a like-for-like comparison with the others.
How much does shower installation cost, by job?
The price depends less on the shower than on where it goes. Putting a new shower back where the old one was is the cheap case. Moving it means new waste and water runs, and adding a shower where there was none adds a fixture, which takes the job outside the consent exemption.
| Job | Cost | Source |
|---|---|---|
| Swap an old shower for an acrylic unit, same place | $900–$2,000 | Superior Renovations, GST not stated |
| New tiled shower, same place | $1,550–$8,250 NZ; $2,000–$9,500 Auckland | Superior Renovations, GST not stated |
| Hinged glass door | $800–1,500 | Superior Renovations, GST not stated |
| Moving the shower to a new position | + $2,000–$6,000 | CheckMyBuilder, excl GST: re-routing waste and water, plus waterproofing |
| Consent, where the job needs one (Auckland) | $1,000–2,500, adding 2–3 weeks | Superior Renovations |
| Contingency for what is behind the tiles | + 15–20% | Superior Renovations |
A worked example: a tiled shower in an Auckland bathroom
Replacing a leaking tiled shower in the same spot in Auckland, with a hinged glass door: $2,000–9,500 for the shower plus $800–1,500 for the door is $2,800–11,000. Add Superior’s 15–20% contingency for what turns up when the old linings come off, and budget $3,220–13,200. No consent fee, because nothing moved and no fixture was added. Move the shower to the other wall and the $2,000–$6,000 re-routing line comes on top.
How much do plumbers charge to replace a shower?
Plumbing is usually the smaller part of the bill. Superior Renovations puts plumbing at 8–12% of a mid-range bathroom renovation and labour across all trades at 40–50%. On a tiled shower most of that labour is the strip-out, substrate, membrane and tiling. A like-for-like swap keeps the plumbing short; moving the waste is what makes it expensive. Sources: Superior Renovations, CheckMyBuilder.
Should you retile the shower or rebuild it?
For most New Zealand bathrooms, a rebuild. They are two different jobs with similar-sounding names. Retiling takes the tiles off, keeps the plumbing where it is, and puts new tiles on. Rebuilding takes the linings back to the framing, replaces the substrate and the membrane, and tiles from there.
Superior puts retiling at $1,800–$4,000and says that excludes waterproofing. If the tiles are coming off, the membrane is coming off with them, and it cannot be re-used. So the honest version of “retile my shower” is usually a rebuild: the difference in price between the two is largely the membrane and substrate, and the membrane is the thing that stops the wall rotting.
When does the shower membrane have to be redone?
Whenever the wall linings come off, whenever a moisture reading or a stain next door says water is already behind the tiles, whenever the shower tray or waste is being changed, and whenever nobody can tell you what membrane is behind the tiles or whether there is one at all.
- Whenever the wall linings come off. A membrane is bonded to the substrate and goes with it.
- Whenever a moisture reading, a soft spot or a stain next door says water is already behind the tiles.
- Whenever the shower tray or waste is being changed, because the membrane has to be sealed into it.
- Whenever nobody can tell you what membrane is behind the tiles or whether there is one at all.
What does the Building Code require for a shower?
Building Code clause E3 Internal moisture requires that wall surfaces next to sanitary fixtures are impervious and easily cleaned (E3.3.4), that surfaces likely to be splashed are impervious and easily cleaned (E3.3.5), and that they are constructed so water splash cannot penetrate behind linings or into concealed spaces (E3.3.6). In Determination 2024/054 two tiled showers failed all three, because cracked grout let water into the concealed space.
MBIE Determination 2024/054, paras 4.3–4.6 and 5.1.1 · checked 16 September 2026. What a proper membrane step looks like, and what to photograph.
Do you need consent to replace a shower?
Usually not, if it goes back in the same place and the house does not gain a fixture. Schedule 1 clause 12 covers the linings and the tiles, and clause 35 covers the plumbing alteration, with an authorised person doing the plumbing work.
Schedule 1, clause 12 of the Building Act 2004 exempts “building work in connection with any internal linings or finishes of any wall, ceiling, or floor of an existing dwelling”. MBIE Determination 2024/054 decided that in an existing dwelling the internal linings include the backing substrate, the wet-area membrane applied to it, the tiles adhered to the membrane and the fixings, adhesives and grouting, so installing a wet-area membrane as part of a tiled shower is within clause 12 and did not require building consent.
Exemptions apply to the work as it actually is, not as it is described on a website. Check your own job with your council before anyone starts. The clauses in full.
How long will you be without a shower?
From strip-out until the tiling is grouted, sealed and cured and the fit-off is done. Superior Renovations puts a budget refresh at 2–5 days in New Zealand and a mid-range full renovation at 2–3 weeks; a shower on its own sits between them. If it is the only bathroom in the house, that is the number that matters.
The sequence is strip-out, repairs if anything is found, plumbing rough-in, substrate, membrane in coats with curing time between them, tiling, grout, silicone, then fit-off. CheckMyBuilder names drying time for waterproofing and tiling as a key part of the schedule, and it cannot be compressed. We put the no-shower window in the written scope. Where the days go.
Questions about showers
How much should it cost to have a shower installed in NZ?
An acrylic shower unit costs $900–2,000 installed and a new tiled shower $1,550–8,250 across New Zealand, or $2,000–9,500 in Auckland (Superior Renovations, GST status not stated). Moving the shower to a new position adds $2,000–6,000 for re-routing waste and water (CheckMyBuilder, excl GST), and a hinged glass door is $800–1,500 on top.

How much does it cost to replace a shower in NZ?
A new tiled shower runs $1,550–8,250 across New Zealand and $2,000–9,500 in Auckland; an acrylic shower unit is $900–2,000 installed (Superior Renovations; the page does not state GST status). Retiling an existing shower with the plumbing left where it is runs $1,800–4,000, and Superior states that figure excludes waterproofing.
Do I need a building consent to replace a shower?
Usually not, if it goes back in the same place and the house does not gain a fixture. MBIE Determination 2024/054 (2 October 2024) decided the wet-area membrane under tiled shower walls is part of the internal linings covered by Schedule 1 clause 12, and clause 35 covers the plumbing alteration where the fixture count does not go up and an authorised person does the work. Check your own job with your council before anyone starts.
When does the membrane have to be redone?
Any time the tiles come off, and any time water has got behind them. A membrane is applied to the substrate and covered permanently, so it cannot be repaired in place: if the wall linings are coming off, the membrane goes with them and a new one goes on.
Can I just re-grout?
Only if the grout is the entire problem. Determination 2024/054 is the cautionary example: cracked grout on two tiled showers let water into the concealed space and damaged flooring and joists, and the showers failed Building Code clauses E3.3.4, E3.3.5 and E3.3.6. If a moisture reading says the wall is wet, re-grouting buys time rather than fixing anything.
How long am I without a shower?
For a shower-only job, the strip-out, membrane, tiling and fit-off each need their turn and the membrane and grout need curing time. Superior Renovations puts a budget refresh at 2–5 days in New Zealand and a mid-range full renovation at 2–3 weeks; a shower on its own sits between them. We put the date in the written scope rather than leaving you to guess.
Is an acrylic unit worse?
Different, not worse. It has fewer joints to fail and it fails somewhere you can see, which is why Superior lists it as well suited to rentals. A tiled shower is a better finish and depends entirely on a membrane nobody can inspect once it is tiled.
