Beyond aesthetics, the RWH‑SB provides reliable warmth, energy efficiency, and safety features that make it a strong contender in the growing market of electric towel warmers.

Heating Performance

The Amba RWH-SB Radiant offers 150 watts of heating power, making it stronger than many compact models. With 10 straight bars, it can warm or dry two towels simultaneously. Heat-up time is 10–15 minutes, which is relatively quick, though towels may require additional time to reach full warmth.

Unlike some lower-wattage models, the RWH-SB provides consistent heating across both vertical and horizontal bars, ensuring even warmth. However, customer feedback suggests the warmth level is moderate rather than intense, making it better for daily comfort than spa-level heating.

Design & Build

• 10-bar straight layout for maximum towel capacity.
• Constructed from 304 stainless steel, resistant to rust, chips, and flaking.
• Available in five finishes: Brushed Stainless, Polished Stainless, Matte Black, Satin Brass, and Polished Gold.
• Rectangular shape with a minimalist aesthetic that fits modern bathrooms.

The brushed stainless finish is versatile and understated, while premium finishes like Polished Gold and Satin Brass elevate the look for luxury interiors.

Safety features

The Amba RWH-SB Radiant prioritizes safety in both design and materials. Its bars are constructed from 304 stainless steel, which is naturally resistant to rust, corrosion, and surface damage, even in humid bathroom environments.

The unit is engineered to operate at a safe temperature, allowing it to be touched without risk of burns, while still being effective at warming towels. For additional safety, the RWH-SB includes an integrated on/off switch, giving users a simple way to cut power when the warmer isn’t in use.

For hardwired installations, the towel warmer is designed to meet standard electrical safety codes, ensuring that wiring is safe and reliable. Its durable construction and thoughtful design make it a low-maintenance, worry-free addition to any bathroom.

Additionally, the minimal design leaves no exposed sharp edges or parts, reducing the risk of accidental injury, and the wall-mount system keeps the unit securely fixed in place.

How to turn off the towel warmer

Turning off the Amba RWH-SB is straightforward. For plug-in models, simply use the built-in on/off switch located on the unit to cut the power. This makes it easy to switch off after use or overnight.

For hardwired installations, you can pair the towel warmer with a wall switch or a programmable timer. This allows for more flexibility, such as scheduling the warmer to turn on before showers and automatically shut off afterward, saving energy and extending the unit’s lifespan.

Some users also pair the warmer with a smart plug or home automation system for remote control, giving them the convenience of turning it on or off without needing to physically access the unit. This combination of safety and convenience ensures that the towel warmer is easy to manage while remaining energy-efficient.

Installation

One of the standout features of the RWH-SB is its dual installation option — it can be hardwired for a seamless, built-in, cordless-style look or used as a plug-in unit for easier DIY setup.

• Hardwired installation: Recommended for permanent bathroom integration.
• Plug-in option: Convenient for renters or those who prefer flexibility.

The unit includes an integrated on/off switch, though many users pair it with a timer for scheduled heating.

Energy Efficiency

At 150 watts, the RWH-SB consumes more energy than compact models (60–80W), but this higher wattage allows it to warm multiple towels simultaneously. For households with frequent towel use, the balance between energy consumption and drying capacity is practical.

Versatility in Use

While primarily designed for bathrooms, the RWH-SB is also effective in:

• Laundry rooms → for drying delicates and hang-dry clothing.
• Mudrooms → for warming jackets, gloves, or ski gear.
• Wet rooms → for keeping towels fresh and reducing damp odors.

This versatility makes it more than just a towel warmer — it’s a multi-purpose drying solution.

How does the Amba towel warmer work

The Amba RWH-SB Radiant uses built-in electric heating elements embedded inside each of its 10 horizontal bars. When the unit is powered on, these elements generate heat that spreads evenly across every bar, ensuring that towels warm uniformly without cold spots.

The 150-watt heating system is designed to be energy-efficient while still powerful enough to dry two towels at once. In practice, towels typically reach a comfortable warmth in about 10–15 minutes. The design also allows heat to radiate gently into the surrounding space, which can slightly warm the bathroom, making those chilly mornings much more comfortable.

For households with multiple users or frequent towel use, this even and consistent heating is a major convenience. Unlike lower-wattage compact models that may leave towels partially damp, the RWH-SB ensures towels are ready to use quickly, while preventing excessive energy use or overheating.

Durability & Warranty

Constructed from 304 stainless steel, the RWH-SB is built to resist rust and wear. However, its 2-year warranty is shorter than competitors like Amba HCMB (10 years on frame) or WarmlyYours Tahoe (5 years + lifetime support). This makes it a solid but less future-proof investment.

Final Thoughts

The Amba RWH-SB Radiant stands out as a heated towel warmer that balances practicality with modern design. Its dual installation option makes it appealing for both homeowners and renters, while the 10-bar layout provides ample drying space for multiple towels. Although its warmth level is moderate compared to spa-grade models and its warranty shorter than premium competitors, it remains a reliable choice for everyday comfort.

If you’re searching for a towel warmer for bathroom use that doubles as a versatile drying rack for laundry rooms or mudrooms, the RWH-SB is a strong mid-range option. With finishes ranging from understated stainless steel to luxurious polished gold, it can fit seamlessly into both minimalist and high-end interiors. For anyone considering a wall mounted towel warmer or plug-in unit, this model offers the flexibility and performance needed to elevate your daily routine.
