What to Know About Toilet and Washroom Door Sizes

There is no single defined standard door width. In addition to door size heights, which are dependent on ceiling heights, doors widths can be bespoke to the frame that they will fit in many cases. However, some of the most popular width measurements for different categories of doors in the UK include the following:

  • 24 or 27 inches (610 or 686 mm): This is a small type of door size that is normally only used for tight interiors or restricted spaces, such as an airing cupboard, utility room or laundry area. This size is too small for washrooms.
  • 30 inches (762 mm): This is the most common internal door size seen in most of the UK, so it can be considered a ‘standard’ of sorts. This width creates a door opening with sufficient room for a standard toilet.
  • 33 inches (or 838 mm): The largest of these popular sizes is also a common industry standard, which complies with Document M of the UK’s Building Regulations relating to the proper access to and use of different structures.

There is also another less popular standard of door size, which is an 18-inch or 21-inch door width (457 mm or 533 mm). This door is not appropriate for the presence of any kind of toilet and sink – and is usually used as a wardrobe door.

As a result of the issues that come up when it comes to width, washroom door sizes are an important aspect of inclusive design – because an improper size will prevent a person living with a disability or using a wheelchair to access the space.

We will provide a few tips, but you can avoid the headaches of finding the right washroom door size in a public space by using our industry-leading design and installation services. Please feel free to get in touch with us today to learn more.

As a result, we are well-placed to provide information on washroom door sizes. Nonetheless, there is much more to a project than getting the washroom door size right.

If you are embarking on a design for new washrooms in an office, school or another type of public space, make sure you keep the following points in mind:

  • Measure the door space: You need to make sure that you are precise in measurements when planning washroom requirements, which will help you to calculate precisely how many 33 inch doors you can fit into a space.
  • Consider ceiling heights: You need to be able to stand in front of the door opening as well as sit in a chair, but the best door width may depend on the height of the ceilings. Tall doors benefit from a larger width for support.
  • Never neglect accessories: Providing a 33-inch door for wheelchair users is great, but you can make a stall much more comfortable and safer by installing accessories such as handrails, non-slip mats and distress alarms.
  • Lower heights accordingly: 400 mm to 500 mm disabled toilet heights are the official standard, but the most common and usable accessible toilet height is 450 mm. You can also lower sinks and toilet roll dispensers.
  • Dedicated stalls: Although an inclusive design will let anybody use a space, you can also opt for a large dedicated stall. This gives you more room to fit a higher number of 30-inch doors and is useful for accompanying carers.

These tips can help, but getting the most suitable design in a commercial or public space can be very tricky. There are plenty of different ways things can go wrong. For example, there is no worse thing for a project than a time delay. We use building information modelling (BIM) to keep our projects on time and track.
