1200 x 900 Shower Enclosures

A 1200 x 900 shower enclosure gives you plenty of room to move without feeling boxed in. It’s a brilliant size if you like a relaxed, open showering space or you’re upgrading a larger bathroom. The wider footprint also makes stepping in and drying off easier. If you’re working with slightly less room, a 900 x 900 shower enclosure offers a compact alternative that still feels comfortable.

There’s lots of choice in our selection of 1200 x 900 enclosures, from simple frameless shower enclosures to black grid designs. Think about door type, access space and how the enclosure sits with your tiles and lighting. Extra width can make sliding or pivot doors feel smoother in daily use. Matching the frame or handle finish to your brassware helps tie the whole room together without any fuss.

Every one of our 1200 x 900 shower enclosures is made from high quality materials, so you can choose with confidence. Thicker glass makes a noticeable difference to how solid the doors feel. Many designs come with generous guarantees, with customer feedback highlighting how sturdy they are in real homes. Plus, enjoy free standard UK delivery over £499 to keep your project moving.

Toreno 8mm Rectangular Sliding Door Shower Enclosure - Easy Fit Large Image

Great choice

18th May 2026

Good quality item. Delivered securely by Thurs party. Plumber had a little trouble with the magnetic strip which keeps the sliding door closed but when he worked out that it matters which way round it goes (just test the magnetic connection before put it in), it worked fine. Looks great 😃

Monza 1200 x 900mm Sliding Door Shower Enclosure + Pearlstone Tray

Really smart

4th May 2026

Looks super smart in our newly revamped bathroom. Took quite a while to work out the door magnet had to be slid down the edge of the metal frame from the top!

Looks amazing

30th April 2026

Oooh the measuring!!!! Luckily we could cover the error holes in the tiles. The instructions are poor and tiny. Use the website to download and enlarge. The measurements are very vague at best, we ended up drawing the elements on the shower tray, coz if you get it wrong the magnetic strips wont meet. Best to do long side 1st. It was a huge learning curve and we class ourselves as very competent DIYers. But it looks great and no messy runners
