Gainsborough Duo Black Slim

Slim shower unit

Hugely practical if you're short on space. These Gainsborough showers are designed to be ultra-slim, so even in the smallest of enclosures, you should have plenty of room.

Gainsborough Duo Black Finish

Piano black finish

Electric showers don't have to be boring or bland, they can pack as much style as a mixer or digital shower if not more. Just take a look at the piano black finish on this Gainsborough Duo and you'll know exactly what we mean. It's contemporary but neutral so matching it with the rest of your bathroom will be easy.

Gainsborough Duo Black Power Settings 2
Gainsborough Duo Black Power Settings

On/off button with 3 power settings

Whether you’re eco-conscious or after the invigoration of a lifetime, Gainsborough can cater with its three sublime power settings and easy to use controls. Simply turn your shower on using the on/off button and enjoy.

Gainsborough Duo 8 Multifit Options

Flexible installation with eight entry points

Gainsborough has purpose-designed their Duo showers to be as easy to install as possible. The Duo boasts eight entry points for water and electricity, takes both push fit and compression fit inlets, and has stand-offs to accommodate different distances from the wall. This means you can retrofit it over almost any other electric shower. It’s the flexibility that every shower should have.

Gainsborough Duo Black Handset

Rub clean nozzles & 3 spray modes

With the Gainsborough Duo you don’t just get 3 power settings but you get 3 spray modes too. Just rotate the dial on the showerhead itself to move between standard and massage modes. And if you live in a hard water area and suffer from limescale, you’ll be please to hear that it just wipes off the nozzles.

Gainsborough Duo Black Handset Holder

Adjustable handset holder

Everyone is a different height so it’s important to be able to customise where your showerhead sits for maximum comfort whilst showering. Not only can you do this with this Gainsborough shower but you can also adjust the wall fixings so the riser rail can be fitted almost anywhere on the wall. You’ll also be pleased to hear that the stainless-steel hose supplied won’t kink or twist as your old shower hose did.
