If you’ve got an awkward corner to fill, a quadrant shower enclosure is almost always the right shape. The curved front lets the doors slide round the bend instead of swinging out into the room, so it eats up far less floor space than a square enclosure with a hinged door. For a tight square corner, an 800 x 800mm quadrant is the classic answer. If one wall is longer than the other, an offset quadrant fits better. That’s the whole decision in a nutshell, and below we’ll go through how to get it right.

This guide covers how to measure your corner, the difference between a standard quadrant and an offset quadrant, which size to pick, finishes that actually suit the room, and the bits people forget (the tray and the waste). There’s a size table near the end if you just want the short version.

Why a Quadrant Works in a Corner

A quadrant enclosure has two straight sides that sit against your two walls and a curved front that bridges them. That curve is the clever bit. The doors slide along the curve rather than opening outwards, so you don’t need any clearance in front of the shower. In a small bathroom where the door would otherwise swing into the loo or the radiator, that’s the difference between a usable room and a constant game of dodge-the-glass.

Compare that to a square corner enclosure with a hinged or pivot door. Those need open floor in front to swing into, and in a tight room you simply might not have it. A quadrant sidesteps the problem entirely. The curved profile also softens the look, so the shower doesn’t dominate the corner the way a boxy enclosure can.

Most quadrants come as double-door units, meaning two panels slide apart from the centre to give you the opening. The Litchfield Glide Matt Black Double Door Quadrant 800 x 800mm at £189 is a good example of the breed: a space-saving quadrant design that fits neatly into the corner, with smooth sliding double doors that need no extra clearance space outside the shower. That’s exactly the behaviour you want in a small room.

How to Measure Your Corner First

Before you fall in love with a finish, measure the corner properly. Getting this wrong is the single most common reason an enclosure goes back.

You need three things:

• The length of each wall from the corner outwards, at the height the tray will sit. Measure both walls, because they’re rarely the same and the difference decides whether you want a standard or offset quadrant.
• Whether the walls are square to each other. Old houses almost never have a true right-angle corner. A quadrant has a little tolerance built into the wall profiles, but a badly out-of-square corner needs checking before you buy.
• What’s around the opening. Where does the door open onto? Check there’s nothing in the way of stepping in and out, and that the curved front won’t clash with a basin, towel rail or door.

Measure at floor level and again about a metre up. Walls bow, and if the top is tighter than the bottom you want to know before the glass arrives, not after. As a rule, leave a few millimetres of breathing room rather than buying right up to the wall length. The wall profiles on a decent enclosure are adjustable to take up small gaps, which is what saves you when the plaster isn’t perfectly flat.

Quadrant vs Offset Quadrant: Which Shape?

This is the bit people get stuck on, so here’s the simple version.

A standard quadrant is symmetrical. Both straight sides are the same length, so the curve is an even quarter-circle. It suits a square corner where both walls have roughly equal space. 800 x 800 and 900 x 900 are the common sizes.

An offset quadrant is the same idea stretched along one wall. One side is longer than the other, so the footprint is more of a rectangle with a curved corner. It fits a corner where one wall is noticeably longer, and it gives you more elbow room inside without taking up a big square of floor. The Litchfield Glide Chrome Offset Two Door Quadrant 1000 x 800mm at £279 is the textbook example: the 1000 x 800mm offset design makes excellent use of corner space while offering generous internal showering room.

So the choice comes down to your corner, not your taste:

• Both walls roughly equal? Go standard quadrant (800 x 800 or 900 x 900).
• One wall clearly longer? Go offset quadrant (900 x 760, 1000 x 800 or 1200 x 800).
• Want the biggest shower the corner allows? Offset, every time. You get more standing room for the same intrusion into the room.

If your corner is genuinely irregular or cramped, the smallest offset is your friend. The Litchfield Glide Chrome Offset Quadrant 900 x 760mm at £239 is built for exactly that. It’s described as perfect for smaller or irregular bathrooms where optimising space is key, and the curved quadrant shape enhances the sense of space inside. When a square 800 or 900 just won’t sit right, a 900 x 760 often will.

What Size Quadrant Enclosure Do You Need?

Size is about two things: what your corner can take, and how much room you want to actually wash in. Here’s how the common sizes shake out.

• 800 x 800mm. The go-to for a tight square corner, en-suite or compact bathroom. Comfortable enough for most adults and the smallest standard footprint worth bothering with. The i6 range and Glide range both start here.
• 900 x 900mm. A noticeable step up in space for not much more floor. If your corner allows it, 900 is the size most people are happiest with. The Litchfield Glide Chrome Double Door Quadrant 900 x 900mm at £219 is the neutral, suits-anything pick at this size.
• 1000 x 800mm (offset). A rectangular footprint with a curved corner. More standing room along the longer wall, still corner-friendly.
• 1200 x 800mm (offset). The largest offset before you’re into walk-in territory. For a longer corner wall where you want maximum room without losing the doors. The Litchfield Glide Chrome Offset Quadrant 1200 x 800mm at £289 fits seamlessly into corner installations and gives wide, effortless access through its two sliding doors.

Honest steer: if you can fit a 900, fit a 900. The jump from 800 to 900 is the one upgrade nobody regrets, because that extra 100mm is felt every single shower. Only drop to 800 if the corner genuinely won’t take more. And if one wall is long, don’t waste it on a square 900 when an offset gives you more room for the same money.

One thing to check on every size: the glass thickness. All the Glide and i6 quadrants here use 6mm toughened safety glass, which is the right standard for a sliding enclosure. Thinner than that and the panels feel flimsy; you don’t need 8mm or 10mm on a framed quadrant.

Finishes: Matt Black, Chrome or Brushed Brass

The frame finish is where the enclosure stops being purely practical and starts pulling the room together. Match it to your brassware (the taps, the shower valve, the towel rail) and the whole bathroom looks deliberate rather than thrown together.

Matt black is the modern default and it’s hard to get wrong. It frames the glass crisply and goes with black taps, black accessories and most tile colours. The Litchfield Glide Matt Black 800 x 800mm at £189 is the obvious pick for a small contemporary corner. There’s also a matt black option in the i6 range at 800mm at £209, if you want the same look from a different frame profile.

Chrome is the safe, timeless choice. It pairs effortlessly with chrome showers, taps and accessories, and it suits any scheme, traditional or modern. If you’re not sure where the room is going, or you’re selling and want broad appeal, chrome is the sensible call. Most of the offset quadrants come in chrome for exactly this reason.

Brushed brass is the warmer, more characterful option, and it’s having a real moment. It works beautifully against darker tiles, green and navy walls, and anything with a touch of warmth. The Litchfield Glide Brushed Brass Double Door Quadrant 800 x 800mm at £319 has a premium brushed brass frame and an 800 x 800 footprint ideal for a tight corner. If your corner takes a 900, the brushed brass 900 x 900mm at £229 gives you the same finish with more room. Just one rule: don’t mix warm and cool metals in the same room. Brass frame, brass tap. If you want to plan the rest of the room around it, our brushed brass bathroom style guide covers what goes with what.

Don’t Forget the Tray and the Waste

An enclosure is just the glass. It sits on a shower tray, and the tray needs a waste. People order the enclosure, get it home, and then realise they’ve nothing to stand on. Match the tray to the enclosure footprint exactly: an 800 x 800 quadrant enclosure wants an 800 x 800 quadrant tray, and so on.

For the popular 800 x 800 quadrant, the K-Stone 800 x 800 Quadrant Shower Tray at £189 is the natural match. Its quadrant shape is made for corner installations and maximises floor space, and the low-profile design reduces step-in height for a sleek transition between wet and dry zones. Low profile matters more than people think; a tall tray means a bigger step, which is no fun for kids or anyone less steady on their feet.

The waste is the cheap bit that gets forgotten. A quadrant tray needs a shower waste, and on a low-profile tray you want a high-flow one so it drains quickly without pooling. Browse the shower wastes range and pick a finish to match, or just grab a chrome high-flow waste and be done with it.

Best Enclosure for a Really Small Corner

If you’re working with the bare minimum, here’s the order I’d go in.

For the smallest square corner, an 800 x 800 quadrant is the smallest size worth fitting. The Litchfield i6 Matt Black Quadrant 800mm at £209 is described as ideal for corner installations and a perfect solution for compact bathrooms, en-suites and modern spaces, built from 6mm toughened safety glass. The sliding doors mean no swing clearance, which is the whole point in a room this size.

If your corner is awkward rather than just small (one wall short, the other shorter still, nothing quite square) the smallest offset quadrant tends to fit where a square won’t. The 900 x 760 offset mentioned earlier is the one to look at there.

And if the corner is so tight that even an 800 quadrant is a squeeze, that’s usually the point where a walk-in panel or a wet-room layout starts to make more sense, because you drop the doors and the tray altogether. Our guide to whether a walk-in shower is right for your bathroom weighs that up. For most corners though, a quadrant is the simpler, cheaper answer, and it’s what I’d reach for first.

Frequently Asked Questions

What is a quadrant shower enclosure?

A quadrant shower enclosure has two straight sides that sit against your two walls and a curved front that joins them, forming a quarter-circle footprint. The doors slide along the curve, so it fits neatly into a corner without needing any clearance space in front. It’s the go-to shape for small and corner bathrooms.

What is the difference between a quadrant and an offset quadrant?

A standard quadrant is symmetrical, with both straight sides the same length, so it suits a square corner where both walls have equal space. An offset quadrant is stretched along one wall, with one side longer than the other, so it fits a corner where one wall is longer and gives you more room inside. Choose offset if one wall is clearly longer, or if you want the biggest shower the corner allows.

What size quadrant enclosure is best for a small bathroom?

For a small square corner, an 800 x 800mm quadrant is the smallest size worth fitting and suits most en-suites and compact bathrooms. If you can stretch to 900 x 900mm, that extra 100mm makes a real difference to comfort. For a corner with one longer wall, an offset such as 900 x 760 or 1000 x 800 makes better use of the space.

Do I need a special tray for a quadrant enclosure?

Yes. A quadrant enclosure sits on a quadrant tray of the same footprint, so an 800 x 800 enclosure needs an 800 x 800 quadrant tray. An offset enclosure needs the matching offset tray. Buy them together so the dimensions line up, and don’t forget a shower waste to go with the tray.

Can I get a brushed brass quadrant shower enclosure?

Yes. Brushed brass quadrants are available in both 800 x 800 and 900 x 900, with a warm brass frame that suits darker tiles and modern schemes. Pair it with brass taps and a brass shower valve so the metals match. Don’t mix brass with chrome in the same room.

Does a quadrant enclosure save space compared to a square one?

Yes, in two ways. The curved front takes up less of the floor than a full square footprint, and because the doors slide along the curve rather than swinging out, you need no clearance in front of the shower. That makes a quadrant the most space-efficient enclosure for a tight corner.
