How much does it cost to install a heated towel rail in NZ?
A hardwired heated towel rail in NZ costs roughly $450–1,100 installed: $94–298 for a wall-mounted rail at Bunnings, $30 for a timer, and 1–2 hours of a registered electrician. Why it is an electrician's job and not a plumber's, where it can go, and what it costs to run.

Key takeaways
- Wall-mounted electric rails were $94 (single bar) to $298 (9 bar) at Bunnings NZ when we checked on 3 November 2026, and the Arlec inline timer was $29.97.
- Fitting one takes a qualified electrician 1–2 hours, including mounting, cabling, connecting and fitting the switch (Eko Heat).
- No NZ electrician publishes a towel-rail price. The nearest published job, an extractor fan, is $400–900 + GST over 1–3 hours (Endeavour Property Services), so we budget about $350–750 for the labour.
- That puts a hardwired rail at roughly $450–1,100 all-in. A freestanding plug-in rail ($84–119 at Bunnings) needs no installation at all.
- An electric rail is a registered electrician's job; a plumber only fits a rail that runs off the hot water system (Mitre 10).
- Running cost is small with a timer: a 100 W rail on 4 hours a day uses 146 kWh a year, about $57 at 39c/kWh. Left on all the time it is closer to $340.
A hardwired heated towel rail in New Zealand costs roughly $450–1,100 installed. A wall-mounted rail is $94–298 at Bunnings NZ (checked 3 November 2026), a timer adds about $30, and a registered electrician takes 1–2 hours to mount it, run the cable and fit the switch (Eko Heat). A freestanding plug-in rail, from $84, needs no electrician at all.
How much does a heated towel rail cost to buy?
| Rail | Price | Type |
|---|---|---|
| Estilo White 5 Bar Round Freestanding | $84 | Freestanding, plug-in |
| Arlec 18W Single Bar, stainless steel | $94 | Wall-mounted single bar |
| Barelli Brushed Aluminium 6 Bar Square Freestanding | $119 | Freestanding, plug-in |
| Arlec 5 Bar 40W, stainless steel | $175 | Wall-mounted ladder |
| Barelli Matte Black Round 5 Bar | $198 | Wall-mounted ladder |
| Arlec 7 Bar 65W Curved, stainless steel | $215 | Wall-mounted ladder |
| Arlec 100W 9 Bar, stainless steel | $298 | Wall-mounted ladder |
| Arlec Heated Towel Rail Timer | $29.97 | Inline timer, fitted by the electrician |
The price climbs with the number of bars, the finish and the wattage, and designer rails from bathroom showrooms sit well above this range. Mitre 10 says grade 304 stainless steel suits most NZ bathrooms and grade 316 is the better choice near the coast, where salt air corrodes the cheaper grade over ten years or more. Prices change, so check on the day.
How much does an electrician charge to install a heated towel rail?
Expect 1–2 hours of labour. Eko Heat, an NZ rail supplier, says a qualified electrician typically takes 1–2 hours from start to finish, which covers mounting the rail, running the cable, connecting it and fitting the switch or timer. We could not find an NZ electrician that publishes a towel-rail price, so the closest comparison is another small bathroom job: Endeavour Property Services in Auckland publishes $400–900 + GST as its average extractor fan installation, over 1–3 hours. On that basis we budget about $350–750 including GST for a towel rail. That is our estimate, not a quote.
| Job | Where it sits | Why |
|---|---|---|
| Swap an old rail for a new one on the same wiring | Low end | Same position, same supply; often under an hour |
| New rail beside an existing power point or circuit, cable surface-run | Low to middle | Short run, no wall opened |
| New rail, cable concealed in the wall | Middle to high | Concealed cabling needs wall access and takes longer (Eko Heat) |
| Timer or smart switch added | Adds a little | Timer from $29.97 plus fitting time |
| Fitted during a full renovation, walls open | Cheapest per rail | The cable goes in with the rest of the electrical work |
Do you need a plumber or an electrician to install a heated towel rail?
An electrician, for an electric rail. Mitre 10 says a plumber is not needed to install an electric heated towel rail, because it connects to the home's electrical system, so a registered electrician does the wiring. A rail that runs off the hot water system instead is a licensed plumber's job. Eko Heat says installation by a licensed electrician is required in New Zealand and Australia, and that DIY wiring voids its warranty. Ask for the certificate of compliance; the EWRB sets out what documentation you should get.
Can I install a heated towel rail myself?
Only the plug-in kind. A freestanding rail that plugs into an ordinary socket is an appliance, not an installation: you unbox it and plug it in. Anything hardwired to a switch or timer in the wall is a registered electrician's work, for the reasons in our guide to who has to be licensed. Read the plug-in rail's instructions for how far it has to stay from the bath, shower and basin, because a socket and a lead near water are the risk.
Where can a heated towel rail go in a bathroom?
Away from the water. NZ bathrooms are split into electrical zones by distance from the bath and shower, and Mitre 10 says IP44 is the usual minimum rating for a towel rail, with IP55 or higher for positions closer to the shower or bath. Eko Heat's IP44 Gordon rail has to be at least 600mm from baths, showers and vanities. The electrician confirms the zone for the exact spot, so pick the position before the visit, along with where the switch goes.
How much does it cost to run a heated towel rail in NZ?
Little, with a timer. Mitre 10 says most residential rails draw 65–130 W and cost 3–5 cents an hour at about 39c/kWh. Our arithmetic at that rate: a 100 W rail on for 4 hours a day uses 146 kWh a year, about $57. Left on 24 hours a day, the same rail uses 876 kWh, about $340 a year. The $29.97 timer pays for itself inside the first winter.
| Use | kWh per year | Cost per year |
|---|---|---|
| 2 hours a day (timer, mornings) | 73 | about $28 |
| 4 hours a day (timer, morning and evening) | 146 | about $57 |
| Left on all the time | 876 | about $340 |
A worked example: adding a rail to an existing bathroom
A 1990s Christchurch bathroom with a power point by the vanity and plasterboard walls. The owners want a 5 bar rail on the wall opposite the shower, on a timer, with the cable hidden in the wall.
| Item | Range | Basis |
|---|---|---|
| Arlec 5 Bar 40W stainless steel rail | $175 | Bunnings NZ, 3 November 2026 |
| Arlec inline timer | $29.97 | Bunnings NZ, 3 November 2026 |
| Electrician: mount, concealed cable, timer, test | $350–750 incl. GST | 1–2 hours (Eko Heat); our estimate from Endeavour's published small-job pricing |
| Indicative total | about $555–955 | Ask for a fixed price once the electrician has seen the wall |
In a rental the same visit is a good moment to check the fan, because the electrician is already there and the healthy homes standard requires a bathroom fan that vents outside. What that costs is in bathroom extractor fan installation cost.
Fitting the rail as part of a renovation
A renovation is the cheapest time to add a towel rail, because the walls are open and the cable goes in with the rest of the wiring. Our bathroom renovation cost guide shows where the money goes, and the measure-and-design visit marks the rail's position and its electrical zone on the plan.
