Gainsborough Electric Showers

The kW rating tells you how much heating power the unit delivers, the range here includes 8.5kW, 9.5kW and 10.5kW models. Higher kW generally gives hotter, stronger flow if your water feed can supply it; an 8.5kW Slim is fine for many small bathrooms, while a 9.5kW or 10.5kW will give a more powerful shower for a family bathroom. Bear in mind that higher kW models need larger electrical cable sizes. Check the specific product page for the model's power and matching cable recommendation before you decide.

Slim Duo and Slim Mono are the two configurations in the Slim range, there are seven Slim Duo options and two Slim Mono options in this selection. Duo and Mono indicate different unit configurations within the Slim line, so you'll find varying features and power ratings between them; you'll see Duo models offered across the 8.5kW–10.5kW range in multiple finishes. Look at the individual product products in our range to compare the exact controls and outlet setups so you can match a model to how you like to shower.

Yes, one model is marked as an Eco Shower and includes water-saving features such as proximity sensors and eco modes, which reduce flow when you step away or select a low-consumption setting. Most other models in the range are standard electric showers without those specific eco features, so if saving water matters to you, choose the Eco-marked model. the eco mode can be useful if you rinse children or pets and want to cut water use between rinses.

The Gainsborough Slim range here comes in White, Piano Black and Titanium Grey. White delivers a classic, clean look that suits traditional or bright bathrooms; piano black gives a modern, high-contrast statement against light tiles; titanium grey offers a softer, contemporary metal-look finish. If you have chrome fittings and neutral tiles, titanium or black will create a cohesive modern look; if you prefer a discreet profile, white is the safest match.
