What a heated towel rack actually costs to run
Published watts, a cited national electricity rate, and the sum written out. This is the number the rest of this category does not publish.
By Sawyer V. · · How we research

The short answer
We earn a commission if you buy through the links on this page, at no extra cost to you. It does not change which products we pick or what we say about them — here is exactly how that works.
Quick picks
Tap any row for the full write-up. Prices are checked against Amazon rather than remembered — where we have no verified figure the button says so.
The formula, and where the rate comes from
watts × hours ÷ 1,000 × price per kWh = dollars.
Every figure on this site uses 18.34 cents per kWh, which is the US average residential retail price of electricity published by the Energy Information Administration in Electric Power Monthly, Table 5.6.A, for June 2026.
We cite and date it because a national average is not your rate. Electricity in Hawaii and electricity in Louisiana are not close to each other, and the honest way to publish a running cost is to show the rate you used so a reader can swap in their own. Find yours on your last bill, divide the total by the kWh used, and rerun the sums below.
Every product on this site, costed
| Product | Published watts | Run | Per day | Per year |
|---|---|---|---|---|
| WarmlyYours Palma, wall rail | 60 W | 24 h | ~26 cents | ~$96 |
| WarmlyYours Palma, on a timer | 60 W | 2 h | ~2 cents | ~$8 |
| WarmlyYours Ibiza, freestanding | 90 W | 24 h | ~40 cents | ~$145 |
| WarmlyYours Ibiza, on a timer | 90 W | 2 h | ~3 cents | ~$12 |
| Zadro bucket | 480 W | 30 min | ~4 cents | ~$16 |
| Lasko CD08200 heater, on high | 1500 W | 15 min | ~7 cents | ~$25 |
The timer is the whole ball game
Look at the Ibiza rows. Same product, same wattage, twelve times the cost, and the only difference is whether it is switched off when nobody is in the bathroom.
Neither WarmlyYours rail has a timer built in. A basic plug-in mechanical timer costs about as much as three months of running the rail, and it turns a $145-a-year appliance into a $12-a-year one. It also means you never have to remember to switch it on, which is the other reason towel warmers stop getting used.
Both buckets do publish timers with auto shut-off — Zadro at 15/30/45/60 minutes, VEVOR at 20/40/60 with a 24-hour delay start — which at several hundred watts is not optional.
Installation costs
Freestanding rail: $0. It arrives, you stand it up, you plug it in. WarmlyYours publishes the Ibiza as freestanding with a NEMA 5-15 plug.
Wall-mounted plug-in: $0 if you can use a drill. WarmlyYours ships the Palma with an “installation manual and hardware kit” and it uses a normal outlet, so there is no electrician involved. Drilling tile properly needs the right bit and patience, and it is not reversible.
Bucket: $0. It is an appliance on a plug.
Hardwired: an electrician. We are not going to quote you a figure, because electrical labour rates vary enormously by region and any number we published would be someone’s wrong number. What we will say is that it is the only option here with a real installation cost, and it is the one this site does not cover. The plug-in versus hardwired comparison is here.
The heating-bill question
People sometimes ask whether a towel warmer reduces their heating bill by warming the bathroom. It does not, meaningfully, and the arithmetic says why.
90 W is 307 BTU/hr, which WarmlyYours publishes. A small domestic room needs thousands of BTU/hr to change temperature noticeably. A rail is a rounding error against a heating system — it warms towels, and that is all it claims.
The related point: a rail is 100% efficient at turning electricity into heat, but so is every resistive heater. Efficiency is not what distinguishes these products; wattage and run time are.
The one number we cannot give you
Every rail and bucket here except VEVOR’s publishes a wattage, which is why this page exists. VEVOR publishes ETL certification, a child lock, an overheat threshold and a timer, and no rated power — so its running cost cannot be calculated.
We are not going to estimate it from the capacity. An estimate presented in a table of calculated figures reads as a calculated figure, and that is exactly the sort of quiet fabrication this site exists not to do.
Every pick in full
3 we would buy. Each carries its Renter-Safe Install Rating, the published specs behind it, and the honest gap in what we know.
1. Lowest draw
WarmlyYours Palma Wall-Mounted Plug-In Towel Warmer
WarmlyYours · TWS2-PLM04PP · best for running continuously
60 W is the lowest published figure here — about 26 cents a day if you never switch it off.
WarmlyYours publishes 60 W, 120 V, 0.5 A and 205 BTU/hr for the Palma. If your plan is to leave a rail on all winter, this is the one to leave on: 60 × 24 ÷ 1,000 × $0.1834 = about 26 cents a day, roughly $96 a year.
The cost of that low figure is the install: it is wall-mounted and ships with a hardware kit, so it drills.
Renter-Safe Install Rating

- Drill
- Time to fit
- Not published
- Power
- Standard outlet
- Reversible on move-out
- With patching
Why: WarmlyYours ships it with a wall-mount hardware kit, which means anchors in tile or plasterboard. The plug end is renter-friendly; the bracket end leaves four holes you would have to make good.

2. Cheapest on a timer
WarmlyYours Ibiza Freestanding Towel Warmer
WarmlyYours · TWS5-IBZ06PP · best for two hours a day, no drilling
90 W and freestanding: about three cents a day on a two-hour timer, and nothing to make good when you leave.
Higher wattage than the Palma, and cheaper to own if you use a timer — which is the point of this whole page. 90 × 2 ÷ 1,000 × $0.1834 = about three cents a day.
WarmlyYours publishes six bars, 307 BTU/hr, 304 stainless, cULus listing and a five-year warranty, freestanding on a NEMA 5-15 plug with a 71-inch cord.

What’s wrong with it
Left on continuously it is about 40 cents a day, the highest figure on this page.
What we can’t tell you
No published warm-up time, so 'two hours' is a routine rather than a spec.

3. Cheapest to own
Zadro 20-Liter Towel Warmer Bucket
Zadro · TWB01 · best for short cycles, low total energy
480 W for a 30-minute cycle is about four cents — the lowest annual cost here if you use it once a day.
High wattage, short run. Zadro publishes 480 W and a timer at 15, 30, 45 or 60 minutes: 480 × 0.5 ÷ 1,000 × $0.1834 = about four cents a cycle, or roughly $16 a year used daily.
The auto-off timer is doing real work here. A 480 W element left running would be a very different number.

- None — it arrives assembled and plugs in

Questions people actually ask
heated towel rack cost
At the US average of 18.34 cents per kWh, a 60 W wall rail left on permanently is about 26 cents a day or $96 a year. On a two-hour daily timer the same rail is about two cents a day. The timer, not the model, is what decides the cost.
heated towel rack installation cost
Nothing for a freestanding or bucket model — they plug in. A wall-mounted plug-in rail costs nothing but your time and a drill. Only a hardwired rail needs an electrician, and that is the one format this site does not cover.
are towel warmers worth it
At three cents a day on a timer, the electricity is not the reason to hesitate. The real questions are floor or wall space and whether the habit sticks.
