The Katalyst for change in showering technology

Advanced water technology means we can all indulge in a drenching, luxurious, all-enveloping shower safe in the knowledge we are using less water than ever when showering!

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

A reconfigured sprayface 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 showering - Exhale

The Exhale Showerhead offers 4 different shower spray options to suit your mood.

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.

Kohler’s Katalyst showering technology delivers luxurious, plump water droplets that retain the heat for longer.

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.

The Exhale Shower comes with 4 different shower spray options – from Silk Spray for a gentle face wash to Drenching for a full showering experience.

For soapy hair-rinsing, when a more intense, drenching spray is required there is a more forceful setting.

Introducing Kohler’s new EXHALE Slide Shower … enjoy the deluge!

Inspired by the delicate appearance of the Dahlia flower, the Exhale multifunction Slide Shower delivers a signature showering experience with a choice of four spray patterns designed to indulge, rejuvenate and calm the mind and body.

 Showering tapware - Exhale

Taking advantage of the very latest innovations in engineering, actuation and sprays, Exhale’s four spray patterns, from one showerhead, ensure a therapeutic and cleansing experience, including:

  • Full Coverage (large luxurious drops)
  • Drenching Rain (exhilarating, drenching circular water pattern)
  • Massage (targets specific parts of the body to revitalize and soothe)
  • Silk Spray (soft, silky drops that are gentle on pets, children and sensitive skin).

The spray pattern is adjusted simply by rotating the spray face.

Kohler’s Katalyst air-induction technology cleverly increases the volume of the water-experience while actually reducing water consumption. By injecting air into the water flow the size of the droplets is increased, creating the perception of larger, fatter, more plentiful water drops.

Durability and longevity is key to Kohler’s design ethos and the Exhale doesn’t disappoint. The spray face features a unique silicone surface with rub-clean nozzles that ensure any mineral deposits are easily wiped away. The polished chrome finish is both corrosion and tarnish-resistant.

The Kohler Exhale Slide Shower, which is also available in a Shower Rose option (again with Katalyst technology) uses a maximum of 9 litres of water a minute and has a 3 star WELS rating.

Technology the Katalyst for water savings

Technology the Katalyst for water savings

Kohler, one of the world’s largest bathroom specialists, is on track to achieve its Net Zero carbon footprint by 2035 – a programme that promotes sustainability while delivering innovative new products to our bathrooms.

The company’s 50 manufacturing plants, spread across six continents, have each reduced carbon emissions and solid waste by 3% per annum since 2008 but it is probably the planet-conscious products we are now seeing in our bathrooms that are attracting the most attention.

Kohler’s toilets have reduced their water usage from 37 litres a flush in the 1930s to 4.5/3 litres in today’s dual flush models. More exciting – in terms of both aesthetics and experience – are the new Katalyst showerheads using Kohler’s patented air induction technology.

Katalyst showerheads cleverly inject air into the water flow – so each droplet of water feels bigger and performs better. By introducing one litre of air to every five litres of water the user feels as though they are having a drenching shower – and in the process enjoys all the associated soothing and relaxing benefits.

There are a number of shower designs using Katalyst technology that ensures all needs are met.

The RainCan is a simple, yet boldly stylish overhead shower in round or square configuration in a choice of 200mm and 250mm sizes. Designed to create a powerful, thoroughly enveloping shower experience its enhanced spray nozzle configuration delivers complete coverage with full, heavy water droplets.
