Shower tray size guide

Posted on Friday 31st August 2018 by James Roberts

Since it’s such an important part of your bathroom design – and because it’s likely to be in place for a long time – getting the right shower tray is essential.

You need something that’s stylish enough to fit with your bathroom design, but sturdy and durable too.

Size is an important consideration when choosing your shower tray, but not always a straightforward one. Here’s what you need to know.

What size shower tray do I need?

There are several types of shower tray, and each one is suitable for different bathroom sizes and designs.

Because of this, choosing the right-sized tray isn’t as simple as picking up the tape measure and buying whatever matches the dimensions of your bathroom.

Some shapes of shower tray, although they might be bigger than others, may pair well with a more compact shower enclosure. For example, you might be able to have a bigger shower tray by installing a shower door that doesn’t swing outwards, which means you wouldn’t have to leave extra space for the door to swing into.

Standard shower tray sizes

There’s no simple “standard” shower tray size. Depth and width vary significantly depending on the shape of the tray. Generally speaking, however, sizes range from:

Average shower tray size
Width and depth 700-2000mm
Height 25-80mm

It’s a broad range, but that’s because there’s such a variety of products to choose from, and each one suits a different kind of bathroom.

Quadrant shower trays

Quadrant shower trays are a perfect choice for smaller bathrooms. With a curved front that’s suitable for a sliding or hinged shower door, you can fit a quadrant tray into any corner of your bathroom.

But being this compact has a downside: quadrant trays don’t offer a very spacious shower. If you like the sound of quadrant trays but feel concerned about not having enough space, look into offset quadrant trays. These use a combination of straight edges and curves to create more showering space but still fit neatly into any corner of a bathroom.

With and depth 800-1200mm
Height 25-80mm

Square shower tray

Square shower trays

Square shower trays are a good fit for any bathroom. This is the most versatile tray shape.

Square shower trays can be installed against any wall or in any corner, and they’re suitable for most types of enclosure.

They’re more spacious than quadrant shower trays and, by pairing them with the right enclosure or cubicle, they can be just as compact, too.

For example, if you added a folding door to a square shower tray rather than a hinged one, you wouldn’t need to leave as much room. If you have a smaller bathroom, but don’t want to put your shower in the corner of the room, a square shower tray can be an excellent – and often more spacious – alternative to a quadrant tray.

Width and depth 700-1500mm
Height 25-80mm

Rectangular shower tray

Rectangular shower trays

Rectangular shower trays tend to be wider than square or quadrant trays, so they’re not quite as suited to smaller bathrooms. However, combined with the right enclosure, a rectangular shower tray can be a neat, compact addition to your bathroom.

With a sliding door, for example, a rectangular shower can take up less space, while still being more spacious than most other options.

Width and depth 800-2000mm
Height 0-45mm

D-shape shower tray

D-shape shower trays

If your bathroom is very small, you might not have space for a square or rectangular shower tray. And if it’s unconventionally designed, you might not have a corner in which to install a quadrant tray.

In these cases, the D-shape shower tray can be a perfect alternative. These trays are very compact, and they only have one flat edge, so they can be installed against a bathroom wall rather than needing to sit in a corner. Their curved shape means they take up less space overall than a square tray.

The downside to a D-shape shower tray is the lack of showering space.

Average size of D-shape shower trays
Width and depth 700-1700mm
Height 40-65mm

Walk-in shower tray

Wet room shower tray sizes

Creating a wetroom or walk-in shower is a great way to make the most of a small bathroom.

There are specialised shower trays for wet rooms. They tend to be slimmer, and they’re set into the floor rather than being raised off the ground.

Wet rooms use a strong waterproof base. The wet room flooring is laid over the top of this base, and this is covered by your choice of bathroom flooring. Read more on our guide to the various types of bathroom flooring if you're unsure.

Raised shower trays

You can raise your shower tray to make it easier to plumb it in. This is particularly useful on concrete floors, on which the waste can’t sink below floor level.

To do this, you need to get a shower tray riser kit.

Visually, a raised shower tray is less appealing, so it’s best avoided unless it’s necessary for installation. It will usually bring the height of your tray up to around 140mm.

Bear in mind that you can’t raise a 25mm shower tray.
