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.

All of the Katalyst showering tapware appliances listed above utilise Kohler’s air injection technology to deliver drenching, all-enveloping showers while using only 9 litres of water a minute (3 star WELS rating). Each is made of solid brass with Kohler’s tarnish and corrosion resistant polished chrome finish.
