What size shower enclosure should you choose?

What size shower enclosure should you choose?

For years, shower enclosures have remained one of the most frequently chosen bathroom fixtures. With such a wide selection on the market, and considering the ecological and economic aspects, this is hardly surprising. However, before making a purchase, a key question usually arises: what size shower enclosure should you choose for the maximum comfort and functionality of your bathroom? We answer this in this article!

Why is choosing the right shower enclosure size crucial?

Choosing the right shower enclosure size is one of the most important steps in bathroom planning. A properly sized shower enclosure impacts comfort, freedom of movement, safety, and functionality of the entire bathroom area. Too small a enclosure can cause discomfort, while too large can complicate the design and take up valuable usable space.

The size of the shower enclosure influences the comfort of showering

The proper size of the shower enclosure also translates into convenient installation of fittings and adequate space for opening the door. Our offer includes a wide range of shower enclosure sizes – from square models to more advanced rectangular enclosures, and ending with simple and minimalist walk-in versions. Choosing the right size allows you to fully utilize the shower area's potential and contribute to the pure pleasure of using it.

How to determine how much space you need for a shower enclosure?

Assessing the space for a shower enclosure is key to achieving a functional bathroom design. To know which shower enclosure to choose, it's worth considering several parameters.

  • minimum space requirements and ergonomics
  • space inside the shower area - a comfortable, minimum shower enclosure size is usually 80x80 cm, although 90x90 cm or larger may be more convenient for many users.
  • freedom of movement - the shower user should be able to freely raise their arms and turn around without any restrictions.
  • space for door opening - it is also worth considering the door opening option - Sanplast offers swing shower doors, including inward-opening ones, sliding doors, and folding doors.
  • useable areas in the bathroom - around the enclosure, it's worth ensuring a minimum of:
    70–100 cm of space in front of the entrance, at least 20–30 cm of clearance from walls and furniture if using sliding or folding doors.

When planning the installation of a shower enclosure, it will be necessary to measure the space where it will be installed. It is worth measuring the length and width of the intended shower area. The angles and verticality of the walls are also important – minor curves can be compensated for with adjustable wall profiles, which are used in Sanplast enclosure designs. When adding a shower tray to the enclosure, the location of the water outlet and the method of installing the siphon are also crucial. Consider recessing the shower tray into the floor or mounting it on the floor – this modernizes the shower area while reducing entry barriers. However, mounting the shower tray on a spatial frame and enclosing it with an aluminum enclosure is an equally good idea – this allows for constant access to the space under the shower tray, as this can be extremely important during maintenance work – in which case, the appropriate installation height must be adjusted.

What are the standard dimensions of shower enclosures?

Wide choice of shower enclosures sizes

The most common standard shower dimensions are:

  • 80x80 cm,
  • 90x90 cm,
  • 100x100 cm,
  • Rectangular variants (e.g., 80x100, 80x120 cm)

Each of these sizes can be found in Sanplast's offer—square, rectangular, and semicircular enclosures, available with various door types (swing, sliding, folding), and in versions combined with acrylic or mineral cast shower trays.

80x80 cm shower enclosures – who are they for?

An 80x80 cm enclosure is a popular choice for smaller bathrooms, especially those in apartment buildings, where every square inch is at a premium. These dimensions provide basic bathing comfort and are easy to incorporate even into challenging layouts. This size is sufficient for users with an average build. 80x80 cm shower enclosures are available in the following series: FRIS, TX5b, Freezone, Free Line II, and Exa Line. Furthermore, a shower area of ​​this size can also be created with a walk-in enclosure, providing an even wider selection.

90x90 cm enclosures – the gold standard of comfort

In the opinion of many users and designers, the 90x90 cm enclosure is the most versatile and comfortable size for several reasons:

  • it provides significantly greater freedom of movement,
  • enables more comfortable bathing,
  • does not restrict dynamic movements.

Sanplast offers a wide selection of 90x90 cm enclosures in various shapes: square, semicircular, with sliding or swing doors. It is the perfect combination of ergonomics, functionality, and aesthetics—which is why this size is considered the gold standard in most bathrooms.

100x100 cm and larger enclosures – the Luxury of space

If space allows, it is worth choosing a 100x100cm or larger shower enclosure. This version ensures a very comfortable shower – even for two people – and allows for the installation of an XXL rain shower head, a seat, or additional accessories.

Asymmetrical enclosures (e.g., 80x100, 80x120 cm)

Rectangular and asymmetrical semicircular enclosures are the perfect compromise between comfort and space saving. They allow you to utilize the longer bathroom wall without taking up much width. Furthermore, a shower area can be created in an available niche. Dimensions such as 80x100, 80x120, and 90x120cm are particularly popular in medium-sized apartments. Our offer guarantees a wide selection of rectangular and asymmetrical enclosures – each series offers products that will work perfectly as a bathroom accessory in any style.

Frequently Asked Questions (FAQ)

What size shower enclosure is best for a small bathroom?

For a small bathroom, 80x80cm enclosures and semicircular solutions are best, as they make optimal use of space. For very small spaces, consider enclosures with sliding or folding doors, thus saving space before entering the shower area. If the bathroom has a long, narrow niche, an asymmetrical 80x100cm enclosure is a great solution, offering more comfort than a square one without visually cluttering the room.

What size shower enclosure is best for a larger bathroom?

In larger bathrooms, the design options are much wider – so it is worth considering 90x90cm, 100x100cm, or larger rectangular models (e.g., 100x120cm or 90x140cm). These sizes provide full comfort when using a rain shower, allow for the installation of a bench, and allow for a more luxurious shower area. Large shower enclosures offered by Sanplast—especially walk-in designs or the elegant versions of the Altus or Exa Line series—fit perfectly into modern, spacious bathroom designs.

What is the minimum comfortable size for a shower enclosure?

90x90cm is most often considered a comfortable size. Although 80x80cm enclosures are also functional and popular, the larger space allows for freedom of movement. For taller individuals or those who prefer longer, relaxing showers, rectangular or semicircular, asymmetrical models are a better choice.

What enclosure dimensions are recommended for seniors?

Seniors are particularly recommended for enclosures measuring at least 90x90cm, preferably with easy entry and wide doors, or walk-in solutions. Enclosures with sliding or folding doors are a good solution, as they require little strength and do not restrict the space in front of the enclosure. Seniors often choose rectangular 90x120cm enclosures, which allow for free use of the shower seat. Sanplast also offers mineral shower trays that can be installed flush with the floor, as well as those with anti-slip surfaces, thus increasing the safety of the bathing area.
