Plan the bathroom door width around the people who use the room. If someone in the house uses a walker or wheelchair, or may come to, plan for a clear opening of at least 32 inches. That’s the figure the ADA standards use, measured with the door open 90 degrees, from the face of the door to the stop on the opposite side. A door’s labeled size isn’t its clear opening, so measure the opening itself.

A bathroom can be remodeled from floor to ceiling and still be hard to get into with a walker or wheelchair. Sometimes it’s impossible. The fixtures change and the door stays narrow. Widening it later means opening a finished wall and its trim a second time. So the door belongs in the layout conversation, with the rest of the room.

Bathroom Door Width Is Measured at the Clear Opening

That 32-inch figure comes from the ADA accessibility standards, which set a clear width of at least 32 inches for a door opening. For a swinging door, the clear opening is measured with the door open 90 degrees, from the face of the door to the stop on the opposite side of the frame. The stop is the thin strip on the frame that the closed door rests against. The clear opening, then, is the open space a person passes through.

Those are federal accessibility standards, written for the buildings the public uses. They aren’t a residential code, and they don’t tell you what your house has to have. For a home, treat 32 inches clear as a reference measurement instead. It’s a sound one, because it’s the figure those standards use for a door someone has to get through.

A door sold or labeled at one size can leave a smaller clear opening than the label suggests. The open door takes up part of the frame. So do the stops and the hinges. Measure the opening, not the door — that gap is what a walker or wheelchair has to clear.

Who Does the Bathroom Door Have to Work For?

The door has to work for anyone in the house who uses a walker or wheelchair. It has to work for someone who needs another person’s help in the bathroom, because two people may need room to get through together. And it has to work for a household that plans to stay in this home as everyone gets older.

AARP‘s remodeling guidance calls doors the number one obstacle to a usable bathroom when someone needs help or uses a mobility aid. So the opening outranks the finishes. However the room turns out, it doesn’t help anyone who can’t get through the door.

The door also has to work for guests — a parent with a walker who’s coming to stay over the holidays, say.

How Do You Measure the Clear Opening of a Door?

Open the door to 90 degrees. Then measure from the face of the door to the stop on the opposite side of the frame. That number is the clear opening, and it’s the one to compare with 32 inches. The width of the door itself doesn’t count here, and neither does the width of the frame.

Our own guidance on creating an accessible bathroom is to widen the door frame on either side if you’re planning for a wheelchair, and to have the door swing outward or slide.

Write that number down and bring it to the design conversation. A short note on your phone is enough:

  • The clear opening, measured with the door open 90 degrees.
  • Which way the door swings, and what it hits when it opens.
  • What sits on the wall beside the door, such as a light switch.
  • Who uses that bathroom, and whether anyone uses a walker or wheelchair.

Should the Door Swing In, Swing Out or Slide?

It depends on the room, but an in-swinging door can take up floor space inside the bathroom and get in the way of someone using a walker or wheelchair. AARP’s guidance says an out-swing door may work better for a bathroom. In other cases, a pocket door may be the better choice.

A pocket door slides into a cavity inside the wall. Plumbing, wiring or a switch in that wall can rule it out, or mean moving them first. An out-swinging door doesn’t take floor space inside, but it needs clear space in the room on the other side, where it lands when it opens.

The right call depends on the room and the hallway around it. Keeping as much open room as possible inside the bathroom makes it easier to maneuver a walker or wheelchair once someone is through the door. That’s a layout decision. Settle it with your designer while the plan is still on paper, because the swing and the opening get decided together.

When Is the Best Time to Widen a Bathroom Door?

During the bathroom remodel, while the room is already being opened up. As a general rule, widening a door means reframing the opening and redoing the wall and the trim around it. A light switch or another item near the door may have to move too. Doing that work once, in one project, can be the simpler path.

Our guidance on planning your home for aging in place also calls for wider doorways, with step-free entryways, so you can enter and exit safely, even with a mobility aid.

Even if nobody in the house uses a walker or wheelchair, a household that plans to stay put may choose to plan the opening once, during the remodel. It’s a planning choice, not a requirement. What tips it is who may use that bathroom over the years you expect to be in this house.

Frequently Asked Questions About Bathroom Door Width

What is the minimum width for an accessible bathroom door?

The ADA standards set a clear opening of at least 32 inches, measured with the door open 90 degrees from the face of the door to the stop. Those standards are written for public buildings, not houses. For a home, treat 32 inches clear as a reference for anyone who uses a walker or wheelchair, and measure what you have before you plan.

Is a 32-inch door the same as a 32-inch opening?

Not necessarily. When the door is open, it takes up part of the frame, and so do the stops and the hinges. The clear opening can come out smaller than the size on the label. Measure the opening with the door open 90 degrees and use that number, because it’s the one that tells you whether a walker or wheelchair fits.

Is a pocket door a good choice for an accessible bathroom?

It can be. AARP’s guidance says a pocket door may be the better choice in some bathrooms, since it doesn’t swing into the room at all. The catch is the wall it slides into, which, as a general rule, has to be free of plumbing and wiring. So the wall decides this as much as the door does. Ask your designer about hardware that’s easy to grip and use.

Should I widen the bathroom door if no one uses a walker yet?

That’s a planning choice, not a requirement. If you plan to stay in this home as you get older, widening the door during a remodel can be simpler than opening the finished wall again later. Our aging-in-place guidance suggests wider doors so you can get in and out safely with a mobility aid. Decide it with the rest of the layout.

What should I bring to a design consultation about a bathroom door?

Bring the clear-opening measurement, taken with the door open 90 degrees. Say who uses that bathroom, and whether anyone uses a walker or wheelchair. Photos help too: the door, the hallway outside it and the wall around it. Our experienced designers are available for complimentary consultations.
