The most common standard shower tray sizes for walk-in shower enclosures are 1400 x 800mm (51" x 32"), 1500 x 700mm (57" x 28"), and 1600mm x 800mm (60" x 32"). These sizes are widely available and can fit well in many bathrooms.
The average walk-in shower in the U.S. measures 60" x 30", though size options can vary widely, typically up to 60" x 42" for a rectangular shower and 42" x 42" for a square one.
If you're really tight on space, you can opt for a 1400mm bath. It might not be the perfect size for adults to do anything other than shower in, but if you don't have very much space and you need a bath for the kids, it's a great space-saving option.
1100mm and 1200mm Walk-In Shower Screens:
For those with spacious bathrooms or a desire for the ultimate in luxury, 1100mm and 1200mm walk-in shower screens are the way to go. These wider screens create an unparalleled sense of openness and grandeur, transforming your shower area into a true spa-like retreat.
The minimum walk-in shower size, or should we say shower tray, is 900mm in length and 760mm in width. However, this is not a recommended walk-in shower size as water will splash and escape, even when this is concealed by a screen.
Dimensions for a corner walk-in shower may be 1100 x 700 mm (42” x 27”), 1200 x 750 mm (47” x 30”), or 1200 x 800mm (47” x 32”). Depending on the bathroom layout and availability of the space, you may also choose slightly bigger sizes of 1200 x 900mm (47" x36") or 1300x800mm (50" x 32").
For a small space, you might choose a walk-in shower with dimensions of around 35 x 35 inches (90 x 90 cm).
How Big Should a Doorless Shower Be? A doorless shower layout requires a larger footprint than a standard tub or shower stall. Building codes may specify that a standard shower stall must be a minimum of 36 inches by 36 inches while the average doorless shower is about seven feet by four feet with many much larger.
For a walk-in 1500mm x 800mm shower tray, an ideal shower screen size would be around 1500mm.
It's normal for water to splash in a walk-in shower. However, there are things that you can do to stop water from splashing and contain it within your shower space.
Common shower sizes
The standard shower dimensions typically measure 36 x 36 inches, meeting the ADA accessibility requirements. Other common dimensions include 36 x 48, suitable for one person, or 48 x 48, which allows more room for two people.
There are standard measurements and dimensions for bath sizes: The average UK bath size is: 1700mm in length and 700mm wide. A small bath size is: 1400mm-1500mm in length and 700mm wide. A large bath size is: 1800mm in length and around 800mm wide.
A full bathroom includes a sink, toilet, a bathtub and shower or a bathtub/shower combo. The average size ranges from 40-60 square feet, with typical dimensions of 5'x8' to 6'x10'. Common layouts include a linear arrangement along one wall or an L-shaped configuration.
Width: A comfortable width for a double shower is typically between 48 and 60 inches. This allows two people to use the shower at the same time without feeling cramped. Length: The length (or depth, depending on your bathroom design) of a double shower is usually at least 36 inches, but it can be more if space allows.
For a walk-in shower, we recommend a shower enclosure of at least 85cm. This ensures easy entry and exit and is ideal for smaller bathrooms or making the best use of space. For larger bathrooms, consider double-sided walk-in showers or even U-shaped configurations, with wall lengths of up to 180cm.
A luxury size shower is typically over 20 square feet in size, but 12 square feet (3' x 4') is really all the space you need to create a wonderfully personal space.
A shower screen that is 1200-1400mm in length is the optimum length to ensure water is retained in the shower area and the desired style can be achieved. A fixed shower screen without a door also has the added benefit of making cleaning duties easier.
Walk-in showers are doorless. This means they have to be quite large to stop water splashing out. The minimum practical dimensions for a walk-in shower are around 80x120cm but they can be as long as 200cm. Using the shower is a lot easier if the width is over 90 cm.
Walk In Shower Trays Sizes
Usually around 1500mm x 700mm but going up to 1800mm x 900mm, it's possible to buy a large shower tray that would replace your bath yet still leave space for other bathroom essentials like toilets, basins and storage units.
For Small Bathrooms
Keep in mind that the shower enclosure should be wide enough to allow easy movements. So the smallest possible walk-in shower dimensions for a square shower layout is 32” by 32”. While 30” to 35” is the smallest size for a rectangular walk-in shower.
Doorless showers offer several benefits that make them a smart choice for many homeowners. One of the main advantages of a doorless shower is its accessibility. With no threshold or glass barrier, these showers are easy to enter and exit, making them ideal for homeowners of all ages and mobility levels.
Size matters with doorless showers.
Figure on adding at least an additional 24 inches of entryway; most walk-in showers are at least four feet wide by five deep, and many are much larger.
You can either pick a prefabricated design to save money or can design the customized shower of your dreams. Due to the wide range of options, the cost of a walk-in shower spans from $1,000–$15,000, with an average cost of $6,700.
What is the smallest recommended size for a shower? A shower should be 36 inches square (36 inches x 36 inches). For tiny spaces, 30 inches square (30 inches x 30 inches) is the smallest space that can be used for a shower.
