The Best Towel Warmers: 4 Compared (and One to Skip)
We compared a wall-mounted heated towel rack and three bucket warmers on wattage, capacity, timers, safety listing, installation and warranty, using each maker's published specs and manuals.
The short version
The Amba Radiant Hardwired + Plug-in Combo Straight 10 Bar is the best overall: a cETLus-listed, 150 W stainless rack that plugs in or hardwires, runs continuously and carries a two-year warranty. The Keenray CL1 PLUS is the value pick, a 20 L bucket that fits two 40 x 70 inch bath towels and adds a delay timer of up to 24 hours, three heat settings and a child lock. The Zadro Large Towel Warmer Bucket suits buyers who want a plain one-touch bucket with a steel tub, a long 83 inch cord and color options, but it has no delay start or heat setting. Skip the Sharper Image Luxury Towel Warmer: its manual names no safety listing, tells you to unplug it after every use, and the product page and manual disagree on its height. Best for: Amba if you want towels dried and warm on the wall every day, Keenray if you want a hot towel ready when you wake up.

Towel warmers come in two shapes that do different jobs. A wall rack runs for long stretches at a modest surface temperature and dries towels between uses, while a bucket heats one or two towels quickly on a timer and then shuts off. The spec sheets look similar until you check wattage, timer options, which safety mark is named and how long the warranty runs. We picked a well-documented wall rack, a feature-heavy bucket, a plainer bucket with a fuller spec sheet, and a gift-catalog bucket that publishes the least.
A 10-bar stainless wall rack that plugs in or hardwires, is cETLus listed and is designed to run continuously.
Best for: Homeowners who want towels dried and kept warm on the wall every day, with the option to hide the wiring later.
- Ships as a plug-in unit with the parts for hardwire conversion, so it suits a finished bathroom now and a remodel later.
- Amba lists it as cETLus listed, with a 150 W, 1.25 A rating at 120 V and a 120 to 180 F surface temperature range.
- Comes with an illuminated on/off switch on the rack and a two-year limited warranty, and offers six finishes.
- Amba rates it for two towels, and a rack warms them more gently than a closed bucket does.
- There is no built-in timer; Amba's timers and smart switch are add-on wall controls listed for hardwired installs.
- The installation guide calls for a certified electrician, a GFCI-protected circuit and, for plug-in use, a grounded outlet with no extension cord.
- Wall mounting means drilling and fixing it securely, which is a commitment in a rental.
A 20 L bucket for two 40 x 70 inch bath towels with a delay timer of up to 24 hours, three heat settings and a child lock.
Best for: Anyone who wants a hot towel or robe on a schedule without installing anything.
- The delay timer adds time in 30-minute steps up to 24 hours, so a towel can be hot when you get out of the morning shower.
- The manual lists three heat settings (75, 80 and 85 C), a temperature view and a child safety lock.
- Keenray rates it for two 40 x 70 inch bath towels in a 20 L tub, with a 450 W maximum draw and a 6 ft cord.
- The product page summary lists 30/45/60/90 minute heat times while the manual lists 15, 30, 45 and 60, so expect 60 minutes as the safe assumption.
- Neither the product page nor the manual we read names a safety listing such as ETL or UL.
- No warranty term is stated on the product page.
- Keenray warns not to use it to dry wet towels or other damp items.
A plain 20 L bucket with a steel tub, a 15 to 60 minute timer, an 83 inch cord and a complete spec sheet.
Best for: Buyers who want the simplest one-button bucket with a long cord and a documented spec sheet, and do not need a delay timer.
- Zadro publishes a full spec sheet: 480 W max, 120 V, 20 L, 21.25 in tall, 8.5 lb, with an 83 inch cord and built-in cord storage.
- Simple touch-button controls with a 15, 30, 45 or 60 minute timer that shuts the unit off automatically.
- Polarized plug, a one-year warranty, and several color combinations to match a bathroom.
- No delay start and no heat setting, so it cannot have a towel ready at a set time.
- Zadro warns that moisture may discolor the inner tub and that the inner surface gets hot enough to burn.
- No safety listing such as ETL or UL is named on the product page.
- It usually costs about the same as the Keenray, which does more.
A two-towel bucket with a 60-minute maximum timer whose manual names no safety listing and tells you to unplug it after every use.
Best for: Nobody in particular; the Keenray or Zadro does the same job with more features or clearer documentation.
- Four timer settings (15, 30, 45 and 60 minutes) on a touch panel that shows the remaining time.
- The manual rates it for two bath towels of about 40 x 70 inches at 450 W maximum.
- Includes a twist-lock lid, a detachable cord wrap and an aromatherapy box.
- The manual's only compliance statement is FCC Part 15; it names no electrical safety listing such as ETL or UL.
- The manual says to unplug the unit immediately after use and never leave it unattended while plugged in.
- The product page lists 25.5 in tall while the manual lists 20.5 in with bases, so you cannot plan the space from the listing.
- It has no delay timer or heat setting and only a one-year limited replacement warranty, yet costs close to the Keenray and Zadro.

How we judged the field
Five things decide whether a towel warmer earns its outlet. First is type: a wall rack dries and warms towels over long stretches, a bucket heats folded towels fast and then stops. Second is the safety listing, because this is a heater used near water, and a named mark such as cETLus tells you an independent lab checked it. Third is timer and control, since a delay start or heat setting changes how useful a bucket is day to day. Fourth is installation, which for racks means plug-in versus hardwired and the circuit it needs. Fifth is warranty, the clearest sign of how long the maker expects the heating element to last.
The field splits into permanent wall racks, which cost more and involve mounting, and countertop or floor buckets, which are cheaper and need only an outlet. Most buckets share the same basic spec of about 20 L, two bath towels and roughly 450 W, so the differences sit in controls and documentation. We picked one well-documented rack, the bucket with the most useful controls, a simpler bucket with a fuller spec sheet, and a gift-catalog bucket that tells you the least.
Amba Radiant Hardwired + Plug-in Combo Straight 10 Bar Heated Towel Rack
Buy itCheck price on AmazonThe Amba Radiant Hardwired + Plug-in Combo Straight 10 Bar is the pick because Amba documents it properly. It is cETLus listed, draws 150 W at 120 V, and Amba gives a 120 to 180 F surface temperature range and a 10 to 15 minute heat-up without towels. It ships as a plug-in unit with the parts to convert to hardwire, so you can start with a 60 inch cord and hide the wiring during a later remodel. The installation guide says it is designed to run continuously, which is what lets a rack dry towels between showers rather than just warm them. The trade-offs are cost, wall mounting, and no built-in timer: Amba sells timers and a Wi-Fi smart switch as add-on wall controls for hardwired installs. It is rated for two towels and warms them more gently than a closed bucket. The guide also asks for a GFCI-protected circuit and a certified electrician. Buy it if you own the bathroom and want dry, warm towels every day.
The Keenray Towel Warmer CL1 PLUS is the value pick and the most capable bucket here. Keenray rates its 20 L tub for two 40 x 70 inch bath towels and lists a 450 W maximum at 120 V, a 6 ft cord, and a size of 19 x 13 x 13 inches. What sets it apart is the control panel: the manual shows a delay timer that adds time in 30-minute steps up to 24 hours, three heat settings of 75, 80 and 85 C, a temperature view and a child safety lock. That delay start is the feature that makes a bucket practical on weekday mornings. The documentation is less tidy than Zadro’s. The page summary lists 30/45/60/90 minute heat times while the manual lists 15 to 60 minutes, and we found no named safety listing or warranty term on the page. Keenray also warns against using it for wet or damp items. Buy it if you want a hot towel on a schedule without drilling anything.
The Zadro Large Towel Warmer Bucket is the right bucket for a buyer who values simplicity and a clear spec sheet over features. Zadro lists 480 W max, 20 L, a 12 inch diameter, 21.25 inch height, 8.5 lb weight and an 83 inch cord, the longest here, with storage for the cord in the base. Controls are touch buttons for 15, 30, 45 or 60 minutes, after which it shuts off. Zadro describes a steel tub, uses a polarized plug and backs it with a one-year warranty, and it comes in several color combinations. What it lacks is any delay start or heat setting, so you have to switch it on and wait each time. Zadro also notes moisture may discolor the inner tub and that the inner surface can burn. It usually costs about what the Keenray does, which is the catch. Choose it if you will only ever press one button and want it to match the room; otherwise the Keenray does more.
The Sharper Image Luxury Towel Warmer looks like the other buckets on paper: two 40 x 70 inch towels, 450 W, and a 15 to 60 minute timer on a touch panel with a lid that twists to lock. The problems are in its own paperwork. The user guide’s only compliance statement is FCC Part 15, which covers radio interference, not electrical safety, and it names no ETL or UL listing. The same guide says to unplug the unit immediately after use and never leave it unattended while plugged in, which undercuts the point of an automatic timer. The product page gives a height of 25.5 inches while the manual says 20.5 inches with bases, so the listing will not help you plan shelf space. Add a one-year limited replacement warranty, no delay start and no heat setting, and it costs close to the Keenray and Zadro without matching either. Skip it unless it comes as a gift, and if it does, follow the unplug rule.
Amba Radiant Hardwired + Plug-in Combo Straight 10 Bar Heated Towel Rack vs Keenray Towel Warmer CL1 PLUS: which should you buy?
The Amba Radiant and the Keenray CL1 PLUS are not really rivals; they answer different questions. The Amba is a fixture. It lives on the wall, runs for hours at 150 W, dries towels as well as warming them, and carries a named cETLus listing and a two-year warranty. It costs several times as much and needs mounting, a GFCI circuit and ideally an electrician. The Keenray is an appliance. It plugs in anywhere, heats two folded towels in a closed 20 L tub at up to 450 W, and its delay timer means you can set it at night and open it to a hot towel in the morning.
Choose the Amba if your complaint is damp, musty towels and a cold bathroom, and you own the space. Choose the Keenray if you rent, if you want a towel that is properly hot rather than warm, or if you only want the treat a few times a week. Some households end up with both: a rack for everyday drying and a bucket for robes and blankets in winter.
What to look for
- A named safety listing: look for cETLus, ETL or UL in the specs or manual, since an FCC Part 15 line covers radio interference, not electrical safety.
- Rack or bucket: a rack dries and warms over long periods at low wattage, while a bucket heats dry towels fast and then turns off.
- Delay timer: on a bucket, a delay start is what lets a towel be hot when you step out of the shower instead of 30 minutes later.
- Installation needs: for racks, check plug-in versus hardwired, cord length, and whether the maker asks for a GFCI-protected circuit.
- Capacity in towel terms: makers rate buckets by towel size, usually two 40 x 70 inch bath towels, which is more useful than the liter figure alone.
- Warranty length: a stated two-year warranty on a rack or a one-year warranty on a bucket is a baseline; a page with no warranty term is a gap.
Our final take
If you own your bathroom and want towels that are dry and warm every day, the Amba Radiant combo is worth its premium: it is cETLus listed, runs continuously at 150 W, plugs in now and hardwires later, and carries a two-year warranty. If you want hot towels on demand without installing anything, the Keenray CL1 PLUS is the better bucket, mainly because its 24-hour delay timer and heat settings make it easy to live with. The Zadro is a fine plain alternative with a clearer spec sheet. Skip the Sharper Image, whose own manual names no safety listing and asks you to unplug it after every use.
Questions, answered
Is a towel warmer rack or a towel warmer bucket better?
They solve different problems. A wall rack like the Amba Radiant is designed to run for long periods at a modest surface temperature, so it dries towels between showers and keeps them warm. A bucket like the Keenray or Zadro heats one or two folded towels quickly inside a closed tub and then shuts off on a timer. If damp towels and a cold bathroom bother you every day, a rack is the better fit; if you want a hot towel or robe a few times a week with no installation, buy a bucket.
Can I leave a heated towel rack on all the time?
Amba's installation guide says the Radiant is designed to run continuously, and suggests switching it off or unplugging it when it will not be used for long periods. Its rated draw is 150 W, far below a bucket's 450 to 480 W. Running any heater for hours still adds to your electricity bill, so a timer on a hardwired install is worth considering. Check the manual for your specific rack, since not every model is rated for continuous use.
Do I need an electrician to install a heated towel rack?
For a hardwired install, yes. Amba's guide says its units should be installed by a certified electrician to the National Electrical Code, on a GFCI-protected circuit. The plug-in option avoids opening the wall, but it still needs a grounded outlet within reach of the cord and no extension cord. You also need to fix the rack securely to the wall, because it carries wet towels every day.
Can I put wet towels in a towel warmer bucket?
No. Keenray's page says not to use the CL1 PLUS to dry wet towels or other damp items, and Sharper Image's manual says its warmer is for dry fabric items only. Buckets are meant to warm clean, dry towels, robes or blankets. Zadro also notes that moisture may discolor its inner tub. If you want to dry towels after a shower, a wall rack is the right tool.
How hot does a towel warmer get?
It varies by type. Amba lists a 120 to 180 F surface temperature range for the Radiant rack, and its guide warns that overloading the rack makes it hotter. Keenray's manual lists heat settings of 75, 80 and 85 C for the CL1 PLUS bucket. Zadro and Sharper Image do not publish a temperature, but both warn that the inner surface gets hot enough to burn, so lift towels out by the edges.
