ThermoSphere 12V Single Square Electric Heated Towel Bar 500mm – 25W, 6 Finishes
The ThermoSphere Single Square 500mm is a single-end-mounted 12V electric heated towel bar with a square-profile tube (40 × 100mm), ideal where a double-end mount is impractical or a cleaner floating look is preferred.

Made from 304 grade stainless steel, designed and finished in the UK. Available in 6 standard finishes. 25W. 5-year warranty. 12V transformer sold separately.

Key Features
12V SELV — Safe in Any Bathroom Zone
At 12V SELV (Safety Extra Low Voltage) this bar is completely safe in all bathroom zones including Zone 1 (above or inside a bath/shower tray) where 230V appliances are not permitted. No specialist enclosure required.
12V SELVAll bathroom zones
Patented Self-Regulating Element — 50% More Efficient
The dual self-regulating heating element automatically limits maximum operating temperature. When a towel is placed on the bar the element heats to optimum; when temperature is reached output reduces rather than cycling on/off at full power. 50% more energy-efficient than conventional electric towel bars.
