Every British Hot Tub model features the exclusive Clean Zone™ system, an innovative self-dosing bromine technology that ensures your spa water stays sanitised with minimal effort. Using easy-to-replace water cleaning cartridges, this system gradually releases bromine into the water, reducing maintenance and preventing chemical overdosing. Perfect for those with sensitive skin, Clean Zone™ uses bromine cartridges meaning it is chlorine-free, offering softer water without harsh odours or skin irritation. Bromine is also less corrosive than chlorine, doesn’t discolour swimwear, and provides effective water sanitation with no unpleasant smell.

To replace a cartridge, simply twist the cap, remove the old cartridge, and insert a new one – it’s that simple. Combined with the Clear Zone™ Filtration system and Blaster Jet, Clean Zone™ makes British Hot Tubs™ the ultimate self-cleaning solution. Designed to save you time, energy, and money, it ensures your hot tub is always ready for you and your family to enjoy year-round.
