Easy access to new showering technology – no need to go behind the wall!

Not often is a new, high tech bathroom appliance specifically designed to save the homeowner money while at the same time delivering the very best in water saving showering technology! Kohler has done just that with its HydroRail shower columns.

The Torsion HydroRail converts easily from a fixed shower head to a multi-function showering experience.


A luxurious home-spa showering experience, Kohler’s HydroRail is designed to replace a wall-mounted fixed-head shower. It can be installed in an existing shower space without the expense or inconvenience of having to go ‘behind the wall’ and change current plumbing.

Convert your fixed head shower.


Originally developed for the Westin Hotel group – to help them meet their global commitment to reduce their water usage by 20 per cent by 2020 – the HydroRail, designed to deliver an overhead tropical rainshower experience, envelopes the user in a deluge of large, full drops. In addition the user can take advantage of adding a handshower – the Awaken multifunction handshower – for hair washing or a more targeted massaging water spray.

The HydroRail comprises either an arched or square shower column (designed to give maximum height to the showerhead) with a 200mm RainCan showerhead with Katalyst technology; an Awaken multi-function hand shower; a diverter (to switch between overhead and hand shower); and a stainless steel shower hose.

Katalyst technology injects 2.2 litres of air into every 9.4 litres of water to create larger, fuller water droplets that retain heat longer – all the time using only 9 litres of water a minute (3 star WELS rating).

The HydroRail Shower Column is available with a round or square 200mm RainCan showerhead and features the Awaken hand shower with a 110mm diameter sculpted spray face and three different spray patterns accessed by a simple slide tab on the showerhead.

Another option is the Kohler Hydrorail Slide Shower featuring the Awaken showerhead with slide rail and bracket. This again is designed to be retrofitted without the need to go ‘behind the wall’ with the slide rail enabling the user to adjust the showerhead to the exact height required or use it as a handshower for rinsing hair or even the walls of the shower space!

The breakthrough HydroRail from Kohler brings a cost-effective showering upgrade within reach of us all. Trade an outdated fixed wall-mount showerhead for a luxury spa experience using existing plumbing with the Kohler HydroRail shower column or slide shower.
