Standard Size
The standard size of a bathroom door is 32 inches wide by 80 inches tall. This size offers a good balance of accessibility and convenience and it meets the requirements of the International Residential Code (IRC).
For wheelchair users the Americans with Disabilities Act (ADA) recommends a minimum width of 32 inches. However universal design principles often suggest using wider doors – around 36 inches wide – for better accessibility.
Common Sizes
Bathroom door sizes can vary depending on the space and user requirements. Some common sizes for bathroom doors include 24″ x 80″ 28″ x 80″ 30″ x 80″ 32″ x 80″ and 36″ x 80″.
The smallest bathroom door width usually ranges between 24 inches and 32 inches depending on local building codes.
As for the minimum height it is typically between 78 inches and 80 inches per the local building codes. Remember that bathroom doors and interior doors share the same dimensions so they can be found in the same section of hardware stores.
Smallest Size Allowed
The smallest bathroom door width can vary between 24″ and 32″ depending on local building codes. The minimum height for a bathroom door is 78″ to 80″ based on local building codes.

- 24 inch door: Suitable for small bathroom dimensions
- 28 inch door: Slightly wider for improved accessibility

- 36 inch door: Better for universal design and wheelchair accessibility
Building Codes
The International Residential Code (IRC) sets the standards for bathroom doors including a minimum width of 32″ and a minimum height of 80″. Local governments and municipalities have the authority to vary or add specific requirements based on building codes that apply to their jurisdiction.
Some of the key factors to consider when choosing an appropriate bathroom door size are:
- Local building codes which can set minimum and maximum door sizes
- Universal design which might require wider doors for wheelchair accessibility
- Space and layout constraints which can limit the options for door sizes and types
- Personal design preferences such as the use of pocket doors barn doors or frosted glass doors
| Door Width | IRC Requirement | ADA Requirement |
|---|---|---|
| 24″ | No | No |
| 28″ | No | No |
| 32″ | Yes | Yes |
| 36″ | Yes | Yes for universal design |
Wheelchair Accessibility
When designing a bathroom that needs to be accessible for wheelchair users it’s important to consider the appropriate door size. The Americans with Disabilities Act (ADA) requires a minimum bathroom door width of 32 inches to accommodate wheelchair access.
Some homeowners may opt for even wider doors such as a 36-inch door for additional space and ease of mobility.
In addition to width also consider the type of door you install. Pocket doors or sliding doors can be a space-saving and accessible choice in smaller bathrooms as they do not require additional clearance for the door swing.
Additionally using an outward swinging door can further improve accessibility by ensuring the door does not encroach on the bathroom’s floor space which can be especially important in a smaller bathroom.
Universal Design
Universal design principles aim to create spaces that can be easily used by people of all ages and abilities. When selecting a door size for your bathroom considering universal design principles can help ensure your bathroom is usable by everyone.
A 36-inch wide door is a common choice for universal design as it offers the most accessibility for people with mobility devices. Other door types that can improve accessibility include pocket doors or sliding doors which save space and do not require a swing clearance like traditional doors.
Outward swinging doors can also provide more space within the bathroom for mobility and maneuvering.
When planning your bathroom layout it’s important to check with your local municipality and building codes to ensure your design complies with all requirements and safety measures. A well-designed bathroom with universal accessibility in mind can significantly improve the functionality and usability of your home.
