If your bathroom is tight on wall space yet you still want warm, dry towels every morning, a vertical heated towel rail might be the smartest thing you add. It swaps the traditional wide ladder for a tall, slim profile that tucks into corners, beside vanities or even behind a door. For many Kiwi bathrooms, that change of orientation is all it takes to free up precious space and keep humidity under control.
You’ll find them across stylish apartments in Auckland, compact townhouses in Wellington, and classic villas right across the country. They look clean and minimal, and they work hard in our damp winters.
Let’s break down what they are, how they save space, what they cost to run in New Zealand, and how to choose the right one for your home.
What a vertical heated towel rail actually is
A vertical rail is a tall, narrow unit designed to heat and dry towels using a single main column with offshoot bars or pegs, rather than a wide horizontal ladder. The form factor is intentionally slim. Widths of 50 to 200 mm are common, while heights range from 900 to 1800 mm.
Most models sold in New Zealand are electric. You’ll see two connection types:
● Hardwired units that hide the cable in the wall for a tidy look
● Plug-in models that use a visible cable and standard outlet
Hydronic versions exist, but they need a suitable hot water system and are less common here. Electric is the easy option for renovations and retrofits.
Heat output is modest and efficient. Expect 45 to 130 watts depending on size and number of pegs. That is plenty for two to four towels, and it is gentle on power bills when paired with a timer.
Surface temperature sits around 45 to 60 degrees Celsius on many models. Warm enough to dry towels properly, not so hot you cannot touch it. Still, you want sensible placement in family bathrooms.
Why it saves space
The vertical layout trades width for height. That single shift opens up other walls for vanities, mirrors, shelving or art. It also means you can use areas that a standard ladder rail simply would not fit.
Common placements:
● Beside the vanity, between the basin and shower screen
● On a narrow nib wall or a wall return
● Behind a door that opens away from the rail
● Between a window and a corner, where there is only a slim gap
Typical footprint:
● Vertical rail: 100 to 200 mm wide, 1200 to 1600 mm tall, 90 to 110 mm projection
● Ladder rail: 500 to 700 mm wide, 800 to 1100 mm tall, similar projection
In a 1700 mm wide bathroom, that difference can keep the room feeling open instead of cramped. You also reduce the risk of elbows and hips clipping a rail in tight circulation zones.
Drying performance and hygiene
Fast drying is not just a comfort thing. Damp towels add moisture back into the room and they can end up smelling musty. A heated rail gets rid of moisture faster and more consistently.
Vertical rails concentrate heat along the central column, then spread warmth through the pegs and into the towels. With good airflow in the room, one bath towel often dries in 2 to 3 hours. Two or three towels may take 3 to 4 hours, depending on thickness and ventilation.
A few tips to get the best result:
● Hang towels in a single layer with minimal overlap
● Leave a finger-width gap between towels
● Run an extractor fan for 10 to 15 minutes after showers
● Set a timer so the rail preheats before the morning rush
Warmer, drier towels help reduce mould spores and that stale bathroom smell. In a wet, coastal climate, those small gains add up.
Power use and running costs in New Zealand
Electricity prices vary by retailer and region. A fair ballpark for residential customers is 29 cents per kWh including GST. Using that rate, here is what vertical rails typically cost to run.

Most households do not need all-day heating. A 4 hour window during peak use is common, for example:
● 1.5 hours early morning
● 2.5 hours from late afternoon into evening
Smart switches or built-in 7 day timers make that set-and-forget. If you choose a thermostat-controlled model, it will cycle to maintain temperature, which can trim kWh further.
Installation basics and code notes
Anything electrical in a bathroom needs care. In New Zealand, all hardwired towel rails must be installed by a licensed electrician under AS/NZS 3000 and protected by an RCD. Your electrician will also consider the bathroom zoning around showers and baths, then confirm the required IP rating for your chosen location.
Good practice for layout:
● Keep the rail close to where you exit the shower for easy reach
● Mount so the top peg is roughly at shoulder to head height for the tallest user
● Aim for 200 to 300 mm clearance off the floor to help cleaning and airflow
● Avoid positions where towels sit over a floor waste or in a splash zone
What your electrician will want to know:
● Hardwire entry on left or right side
● Exact height to centre of the power outlet in the wall
● Where the timer or switch should go
● The wall type and whether extra nogs are needed
On tiled walls, use a quality diamond bit and go slow to avoid cracking. If you are renovating, ask the builder to add timber in the wall where the rail will mount. A secure fixing stops wobble and extends product life.
Picking the right finish and material for NZ homes
Stainless steel is the gold standard because it resists corrosion, cleans easily, and looks sharp. Most mid to high quality rails use 304 stainless. If you live near the coast or in a high salt zone, 316 stainless adds extra resilience. It costs more but it is worth it in exposed locations.
Popular finishes right now:
● Brushed stainless for a soft, contemporary look
● Matte black for contrast against white tiles
● Brushed nickel or gunmetal for warmth without glare
● Brushed brass for a subtle luxury note
Powder coat and PVD colour finishes both show up in modern ranges. PVD tends to be tougher in day-to-day use. Whatever you choose, avoid harsh chemicals. A microfibre cloth and mild detergent keeps things tidy.
How many towels is realistic
Vertical rails excel with daily-use towels. They do not always suit bulk drying of bath sheets for a six-person household.
Rough capacity guide:
● 45 to 65 W vertical rail: 1 to 3 standard towels
● 90 to 130 W vertical rail: 3 to 4 towels, or 2 bath sheets
If you want to dry a robe as well, pick a model with spaced pegs or an extra bar at lower height so items can hang without touching the floor.
Smart timers and controls
A timer is the simplest way to reduce energy use and improve drying. Options include:
● In-wall 7 day timer with multiple on-off periods
● Touch controller with manual boost mode
● Smart switch or smart plug for compatible plug-in rails
A 1 to 2 hour boost button is handy after a tumble of wet sports gear or winter bath nights. For plug-in models, check the smart plug rating and IPX rating if it sits near moisture.
Common mistakes to avoid
● Mounting too low. Towels drag on the floor and airflow suffers.
● Piling multiple towels on a single peg. The outer layer dries, the inner stays damp.
● Installing in a dead corner with no air movement. Use the fan or open a window briefly.
● Forgetting about door swing. A door that bangs into a rail makes everyone grumpy.
● Running it 24-7. A timer takes 5 minutes to set and can halve your power use.
Vertical vs ladder rails
Both have their place. Here is an at-a-glance comparison to help you choose.
● Space:
○ Vertical: Small footprint, ideal for tight walls and behind doors
○ Ladder: Needs width, doubles as a design feature on open walls
● Towel access:
○ Vertical: Easy grab from pegs, good for kids and guests
○ Ladder: Works well for larger families with multiple bars
● Drying speed:
○ Vertical: Focused heat, fast for 2 to 3 towels
○ Ladder: Even heat across more surface area, better for bulk
● Look:
○ Vertical: Minimal, sculptural
○ Ladder: Classic, hotel style
● Installation:
○ Vertical: Fewer fixing points, simpler template
○ Ladder: Wider span needs solid fixings or nogs
If you have two bathrooms, you might even mix them. A vertical rail for the ensuite, a ladder for the main family bathroom.
When a vertical rail is not the best choice
● You want to dry 5 or 6 towels every day
● You prefer oversized bath sheets exclusively
● Your only available wall is deeply recessed or constantly splashed by the shower
In these cases, a 600 to 750 mm wide ladder rail with 8 to 12 bars will probably suit better.
Care and longevity
Quality stainless rails last for years. Keep yours looking new with simple habits:
● Wipe down weekly to remove mineral spots
● Do not hang wet swim gear that drips heavily without a tray or mat under it
● Check fixing screws once a year and snug them if needed
● If your unit has a detachable face plate, vacuum out any dust near the hardwire entry
Most good brands offer a 5 year or longer warranty on the body and 2 years on electrical components. Always keep your purchase receipt and the electrician’s COC for future reference.
