Gainsborough Mono White Slim

Slim shower unit

It may not be a feature based on style but it's 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 Mono 4 Multifit Options

Flexible installation points

Gainsborough has purpose-designed their Mono showers to be as easy to install as possible. They’ve included 4 different multi-fit options to ensure you can retrofit it over almost any other electric shower. It’s the flexibility that every shower should have.

Gainsborough Mono White Handset

Rub clean nozzles

Ensure your shower stays looking great thanks to the rub-clean nozzles on the showerhead. It allows you to simply wipe away any limescale build-up without a worry of it reducing the performance of your handset.

Gainsborough Duo White 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.

    The shower that I have been using has been discontinued and this was the alternative. Ordered and delivered the next day. Great price and would use Plumbworld again

    Installed by an Engineer. We followed all the rules - switching off at the mains after use etc. Worked 5 times then turned itself into a COLD WATER shower. I guess the heating unit has blown.
