Ultimate Guide to Shower Enclosures

Choosing the right shower enclosure can feel overwhelming. This guide walks you through everything you need to know, from the different types and sizes to what to measure and what else you'll need to buy. Whether you're renovating a small en-suite or fitting out a generous family bathroom, you'll find clear, practical advice here to help you get it right.

What is a shower enclosure?

A shower enclosure, also known as a shower cubicle, is a self-contained showering area made up of glass panels and a door, designed to keep water contained within a defined space. People choose shower enclosures over bath-shower combos or wet rooms because they're easier to install, more affordable, and available in a wide range of sizes and styles to suit almost any bathroom layout. They're also low maintenance and can make a real style statement.

Types of shower enclosures

Shower enclosures come in several shapes and styles, each designed to suit a different bathroom layout or preference. Here's a quick breakdown of the main types you'll find.

  • Quadrant shower enclosures: Curved corner units that fit neatly into the corner of a bathroom. A great space-saving choice for smaller rooms.

  • Offset quadrant shower enclosures: Like a standard quadrant but longer on one side, giving you a more generous showering area without taking up much more floor space.

  • 3-sided shower enclosures: These use two existing bathroom walls to form part of the enclosure, with two glass side panels and a door completing the structure. They’re ideal for awkward or irregular spaces.

  • Bi-fold shower enclosures: The door folds inward in two sections, meaning it doesn't need clearance to swing outward, making them perfect for tight spaces.

  • Hinged shower enclosures: Feature a door that swings outward on hinges for a clean, open feel. They’re best suited to larger bathrooms where there's room for the door to open freely.

  • Frameless shower enclosures: No metal frame around the glass panels, giving a sleek, minimal look. Stronger and heavier glass (typically 8mm to 10mm) is used to compensate. These are a popular choice in modern bathrooms.

Shower enclosure door types

The door type affects how much space you need around your enclosure, so it's worth factoring in before you buy.

  • Bi-fold doors: Fold inward in two panels, requiring very little clearance in front of the enclosure; a good pick for compact bathrooms.

  • Sliding doors: Glide sideways along a track, with no swing clearance needed, making them well-suited to narrow or busy bathroom spaces.

  • Hinged doors: Swing outward like a standard door. These feel spacious and airy, but need clear floor space in front to open properly.

  • Pivot doors: Rotate on a central or offset pivot point rather than standard side hinges. They offer a wider opening than a bi-fold.

  • Walk-in panels: These don’t have any doors at all. Instead, they feature an open-entry design, usually used with large walk-in shower enclosures, which prevents water from splashing out directly.

  • Reduced height doors: Shorter panels for rooms with low ceilings or sloped roofs, such as loft conversions.

Types of shower trays

A shower tray sits at the base of your enclosure and channels water into the drain. Not all enclosures include one, so check before you buy. Here are the main types:

  • Quadrant shower trays: A curved tray designed to pair with a quadrant enclosure. They fit snugly into a corner.

  • Rectangular shower trays: The most common shape. These work with most enclosure styles and suit a wide range of bathroom layouts.

  • Square shower trays: Equal-sided trays that work well in larger, symmetrical shower spaces.

  • Low-profile shower trays: Very shallow depth, designed to sit nearly flush with the floor. They are easier to step into and give a near-wet-room feel without the full installation.

Shower trays come in two main materials: stone resin and acrylic. Stone resin shower trays are the most popular choice. They’re heavy, solid underfoot, and resistant to flexing. They’re also less likely to crack or shift over time, helping preserve the seal around the edges. Acrylic shower trays are lightweight and affordable. However, they can flex slightly underfoot, which puts pressure on seals over time. They’re fine for lighter use, but stone resin is generally worth the extra cost.

Shower enclosure sizes

Shower enclosure heights typically range from 1,700mm to 2,200mm. Most standard bathrooms suit a 1,900mm or 2,000mm height. If you have a low ceiling, such as in a loft conversion or en-suite, look at reduced height options starting at 1,700mm. Taller enclosures (2,100mm to 2,200mm) work well in rooms with high ceilings or where you want a more dramatic look.

Widths range from around 600mm to 2,000mm, depending on type. Standard shower cubicle sizes tend to fall between 800mm x 800mm and 900mm x 900mm for square models, and 1,200mm x 800mm or 1,200mm x 900mm for rectangular ones. These are the most widely available shower cubicle dimensions and suit most average-sized bathrooms.

How to measure a shower enclosure

Start by measuring the space you have available. If you’re planning a corner installation, measure from wall to wall in both directions to get an accurate footprint. For a recessed shower enclosure, focus on the width of the opening. It’s best to measure at floor level for width and at a couple of wall points for shower enclosure height, as walls aren’t always perfectly straight. Allow a small amount of tolerance to ensure a comfortable fit, and always compare your measurements with the manufacturer’s stated dimensions before placing your order.

How to fit a shower enclosure

Most shower enclosures can be fitted as a DIY project if you're reasonably confident with basic tools. The general process involves securing the tray to the floor, fixing the wall profiles to the surrounding walls using a spirit level, then slotting the glass panels into place and attaching the door. Always follow the specific instructions included with your model. If plumbing connections are needed, or if you're unsure about any stage, it's worth calling in a professional. Incorrect installation can cause leaks and may void your warranty.

How to seal a shower enclosure

Once your enclosure is fitted, apply a continuous bead of silicone sealant along every join: between panels and wall profiles, and between the tray and the panels. Use a bathroom-grade, mould-resistant silicone and smooth it with a wet finger or a sealant tool. Leave it to cure fully, usually for 24 hours, before using the shower. Reseal every few years or as soon as you notice cracking or shrinkage, as a failed seal is the most common cause of shower leaks.

How to clean a shower enclosure

Wipe down glass panels with a soft cloth after every shower. This stops limescale and soap scum from building up and keeps the glass clear with minimal effort. For a deeper clean, use a non-abrasive bathroom cleaner or a diluted white vinegar solution. Avoid harsh scourers, which can scratch the glass. Clean door seals and tracks regularly to prevent mould from building up. If your enclosure has a protective glass coating, check the manufacturer's guidance on which products are safe to use.

How to choose a shower enclosure for your bathroom

The best shower enclosure for you comes down to your bathroom's layout, how it will be used, and the look you want to achieve. Work through the key considerations below to narrow down your options.

1. Bathroom space and size

To answer the question ‘What size shower enclosure do I need?’, start by measuring your available floor space. Anything under 800mm x 800mm will feel cramped for most adults. If you're working with a very small bathroom, a 700mm x 700mm quadrant is often the most practical fit. Larger bathrooms can take enclosures of 1,200mm or wider with ease.

2. Where it will be placed

Corner, recess, or freestanding installation all require different enclosure types. A quadrant fits a corner, a 3-sided enclosure works in a recess, and hinged or walk-in styles suit open spaces. Get your measurements right before deciding.

3. Frame colour

Frame profiles come in chrome, black, brushed brass, and brushed nickel. Chrome is the most versatile and works with most bathroom schemes. Black shower doors and gold shower enclosures have become increasingly popular as bold, modern choices. Match your frame finish to your taps and other fittings for a more cohesive look.

4. Glass type and thickness

Glass thickness comes down to the look and feel you want to achieve. 6mm offers a practical, reliable option, while 8mm is a popular choice for its more solid, premium feel. For a truly substantial finish, 10mm glass is typically found on higher-end designs. All modern enclosures use toughened safety glass as standard, and many also feature a protective coating to help repel water and reduce limescale, making cleaning that little bit easier.

5. Any accessories or additional parts you’ll need

Check whether your chosen enclosure includes a shower tray. Many do not, so you may need to buy one separately. You'll also need bathroom wall panels or tiles to protect the surrounding walls from water splashback. A shower waste is also required to drain the tray if not already included.

6. Who will be using the shower enclosure

Think about the people using it daily. Taller users will benefit from a height of 2,000mm or 2,100mm, while wider door openings make things easier if accessibility matters. If young children will be using the shower enclosure, a lower-profile tray and bi-fold or sliding door (with no outward swing to contend with) is a more practical setup.
