Bathroom Door Sizes: Guide & Requirements

Knowing where to start when building a new home or considering modifying your current home can be extremely challenging. There are numerous factors to consider throughout the planning stage of your ideal home; one of the most crucial is the size of your bathroom door. 

As per municipal requirements, bathroom doors should be at least 24-32” wide  but can go up to 36”. 24″ doors are permitted in existing restrooms but must be wider in new constructions. Bathroom doors should be at least 78 to 80” tall, with the standard door measurement as 32″ x 80″.

Standard bathroom door sizes

There are various state-specific standards with recommendations to follow as you choose the size of an interior door. However, the International Residential Code (IRC) only has regulations regulating the size of an egress door.

For instance, all interior doors must be at least 80 inches tall according to the Wisconsin Interior Door Size Regulations. They must also open to a space that is 30 inches wide or 32 inches wide when closed.

The Michigan Interior Door Size Regulations stipulate that interior doors cannot be less than 24 inches wide and must be at least 78 inches tall, demonstrating how widely municipal codes can differ. Doors leading to areas with a floor area of less than 10 square feet are the only exceptions to this requirement.

Before choosing a bathroom door size for your home, consult the building regulations in your state, as the codes vary in interior door sizes.

Minimum Door Width

Based on regional building regulations, the bathroom door can be any width between 24 and 32 inches.

Minimum Door Height

Depending on local construction regulations, a bathroom door’s minimum permissible height is between 78 and 80 inches.

Standard Size for Bathroom Doors

The typical bathroom door measures 80 inches in height and 32 inches in width. You can choose to have a door taller than 80” because some states do not have a size restriction on bathroom doors. 

However, these sometimes need to be constructed to order and will probably be much more expensive than a regular door that is 80′′ tall.

Most people opt to go with a door with a width greater than 30″ for accessibility reasons. Unfortunately, many pieces of furniture sold today will not fit through a doorway less than 30″ wide, which makes furnishing your bathroom tedious.

It is also essential to remember that it will be easier for people to move in and out of a bathroom if your door provides a width greater than 30″. 

Although you may find doors with a width of 24″ in some homes, it is crucial to note that installing a new 24″ door is not permitted. These small-width doors are only allowed when the existing structure in the home cannot support a larger door.

What Justifies a Bathroom Door Wider Than 24″?

Although some properties may have doors that are 24 inches wide, it is crucial to remember that adding a new 24-inch door is not allowed. These narrow doors are permitted only when the home’s existing structure cannot support a larger door. For ease of accessibility, doors should be wider than 24″. Homeowners with 24′′ doors frequently complain that the narrow doorway makes it challenging to pass through. 

While some claim that 24′′ doors are suitable for a pantry, closet, or guest room, they advise that rooms with a lot of people passing through them, such as bathrooms, should have doors with a wider width. 

This will allow people to pass through the area more quickly. A person can fit through a door that is 24 inches wide. However, you can find it quite challenging to move through this smaller space if you need to bring an armload of laundry or towels into the bathroom, for instance.

Moreover, someone in a wheelchair or walker would have difficulty getting through this narrow entrance. Consider some of the precise requirements for door size set forth by the Americans with Disabilities Act to ensure simple access for all those who may use your bathroom.

American with Disabilities Act-compliant doors

Access for people with disabilities should be considered when choosing the bathroom door for your home, especially if you live with someone or receive frequent visitors who use a wheelchair or walker. A small or standard-sized door won’t have enough room for these people.

Take time and visit the Americans with Disabilities Act website if you have any additional queries about the information or are curious about it. They have all the answers on how to make your house more accessible. 

For example, if you’re building a bathroom door for people using a wheelchair or a walker, other things to think about are the door’s swing orientation and a lock that can be unlocked from the other side in case of an emergency.

You don’t want to forget about the handles when creating the bathroom door. Although they frequently make a subtle statement, door handles provide style and highlight your bathroom’s decor.

Door handles and knobs are available in various styles, from contemporary to vintage, and in several finishes, including brass, nickel, and chrome.

4. Door Lock

Is the bathroom in your home a safe space? So it’s crucial to secure the entrance, and there are various sorts of locks for your bathroom. You need a lock that won’t jam while you’re using it, is safe, and is straightforward to operate.

5. Bathroom Over-the-Door Organizer

Over-the-door bathroom organizers are useful space savers whether you live in a tiny space or are trying to maximize your storage options.

You can choose different-sized and-shaped organizers with hangers for towels and clothing.

Bathroom door thickness guidelines

The majority of bathroom doors are 1⅜” thick. However, bathroom doors come in thicknesses of 1½, 1⅝, and 1¾ inches. Therefore, a standard-size door is often thinner than an oversized door, which is more than 90 inches tall and 36 inches wide.

 The thickness of your bathroom door may differ from these measures if you install a glass door. The most typical thickness of the glass is 12″. However, glass with thicknesses up to 34″ and beyond is also increasingly popular.

To ensure that a door is stabilized, the thickness of the glass used to make your glazed door must increase as the height of the bathroom door does. Therefore, the door’s thickness will also need to be increased to fit the thicker glass.


Above are all the factors and features you need to consider in constructing or making any adjustments to your bathroom door. We hope to have given you an edge in the process.
