Whether you’re looking to modernize a dated bathroom or simply want a more accessible shower design, adding a walk-in shower can be a great way to transform your space. One of the most common questions people have when it comes to adding a walk-in shower to a bathroom is, “How much space do you need?”
While there’s no universal answer to this question, there are some considerations you (and your design team) can keep in mind as you plan for a beautiful and well-functioning bathroom.
Walk-in Shower Size Recommendations
The size of a walk-in shower will depend on the size of the room, as well as the size of the existing shower and the configuration of other fixtures. A “standard” shower measures 60″ by 30″ and is what you’ll find in many homes, although walk-in showers can be as small as 30″ by 30″. If you have a larger bathroom with lots of space to work with, you might even consider sizing up.
Don’t Forget Space Between Fixtures
Of course, adding a walk-in shower isn’t just about dimensions; it’s also about the configuration of the space, including the positioning of other fixtures. You’ll want to make sure that there’s plenty of clear space around the entryway of your walk-in shower to minimize tripping hazards. For this reason, most residential building codes require a minimum of 24 inches of clearance around a shower entry.
What About Shower Doors and Vertical Space?
When thinking about walk-in shower measurements, it’s easy to forget about vertical space. However, having plenty of vertical clearance in a walk-in shower can make the space more comfortable and prevent taller users from feeling cramped. As a general rule, showers should have a minimum floor-to-ceiling height of at least 80 inches.
Unless you’re opting for a doorless walk-in shower, you’ll also need to think about the type and size of the door. The size of the door you’ll need will depend on many factors, including the size of your shower. Different shower door designs can also open/close in different ways, such as by pivoting or even sliding open.
For reference, the typical glass shower door size is around 24 inches wide and anywhere from 72 to 78 inches tall.
Walk-In Shower Design Guidelines
Aside from choosing the right walk-in shower dimensions, you’ll also want to think about the overall design and aesthetic of your new shower. One of the most important things to think about here is storage. For a neat look, you might consider adding built-in niches to hold shampoo and soap bottles within arm’s reach. Others may prefer to add their own removable shelving rather than having an additional area of the shower to clean.
When designing your shower, think about comfort and functionality as well. If you have the space, you might consider adding a built-in bench for added accessibility and comfort.
When it comes to the look and feel of your new shower, the materials you choose can also have a major impact. If you want your shower to be a focal point in the room, you might consider using bolder tile colors or unique patterns to make your new walk-in shower stand out.
Recommendations for Small Bathrooms
Adding a walk-in shower to a small space may seem like a challenge, but with a qualified design team, it doesn’t have to be. There are plenty of inspiring small bathroom designs with walk in shower components. The key is to ensure that there’s enough clearance between fixtures to keep the shower up to code.
For many smaller bathroom spaces, designers will opt for space-saving features, such as a sliding glass shower door instead of a swinging door. In some cases, a doorless walk-in shower may even be practical in a small space.
