Advanced water technology means homeowners can indulge in a drenching, luxurious, all-enveloping shower safe in the knowledge they are using less water than ever.

Kohler, the US global design force in bathroom design and technology, is the brand behind the patented Katalyst showering technology.

A reconfigured spray face and an air-injection mechanism create a super-indulgent 'rainshower' experience whereby the user receives even, wide coverage, without any wasteful overspray, regardless of the water pressure. Katalyst technology introduces 2.2 litres of air into every 9.4 litres of water, creating larger, fuller water droplets that retain heat longer**.

The fullness and force of the water spray emulates that of a heavy rain shower, courtesy in part to the redesign of the nozzles — larger diameter, different configuration and revised angle. The unique patented technology of Katalyst results in a better cleaning and hair rinsing performance — and an overall indulgent, luxurious experience.

And while the technology is high performance, there are no visible changes to the showerhead's exterior and no extra noise.

Kohler's Katalyst rainshower experience is available in a number of showering tapware options — wall and ceiling mounted showerheads plus showering columns.

Kohler showering tapware with Katalyst technology is rated 3 star WELS and is available from selected plumbing merchants nationwide.
