Will a Shower Stall Fit Through Your Door? Measure the Path First

A one-piece shower stall only fits if every door, hall and turn between the truck and the bathroom is wider than the stall's widest piece; a multi-piece shower (EZ Able lists some as fitting 30-inch doorways) is the safer pick for a finished house, so measure the path before you order, because Made-Upon-Order showers cannot be returned.

Facts reviewed by the EZ Able team.

The short answer

Measure the narrowest point between your driveway and the bathroom, not just the bathroom door. If that opening is wider than the shower's widest piece, it fits. If it is not, choose a multi-piece shower, which ships as separate base and wall panels. One-piece showers are molded as a single unit, so they suit new construction, where the walls are not up yet. Multi-piece showers suit remodels, where they have to pass through doors that already exist.

Why the bathroom door is the wrong place to start

Most people measure the bathroom door, see 30 or 32 inches, and stop. The stall has to get there first. It travels from the delivery truck through the front or garage door, down a hall, around at least one corner, and then through the bathroom door. The tightest spot on that route is the number that matters. In older Michigan homes that is often a hallway corner or a basement stair, not the bathroom doorway.

Two things make this harder than moving a sofa. A shower stall does not bend, and it does not come back. Our Made-Upon-Order showers are not returnable, so a stall that will not fit is a costly mistake. That is why we would rather you measure twice and call us once.

How to measure the delivery path

Grab a tape measure, a pencil and your phone. Walk the route the crate will take and write down:

1. The clear width of every door on the route. Open the door to 90 degrees and measure from the stop to the face of the open door. That matches how the 2010 ADA Standards measure clear width (section 404.2.3). It is smaller than the door slab itself, because the hinges and stop take space.

2. The width of each hallway at its narrowest point, including trim, radiators and light fixtures.

3. Every turn. A hall can be wide enough and still be impossible if the stall cannot pivot at a corner. Flag any corner where the hall is narrow on either side, and photograph it.

4. Stairs, if the bathroom is up or down. Note the width, the ceiling height at the landing, and anything that hangs low.

5. Ceiling height in the bathroom. Stalls are tall, so check height as well as width. For example, one 60 x 48 curbless multi-piece stall on our site lists a height of 81.5 to 82.5 inches.

Then take a photo of each tight spot with the tape in the shot and send it to us. We will check it against the unit's piece sizes before you order. Call 877-392-2531.

One-piece vs. multi-piece: how they differ at the door

Our walk-in shower kits page puts the tradeoff plainly: one-piece has no wall seams; multi-piece is easier to carry through narrow doorways. Neither is better in every case. Decide on the route into the room.

What about the 36-inch door question?

A common version of this question is "will a 37-inch shower fit through a 36-inch door?" Often yes, but check what the 37 inches is. If it is the stall's outside width and the door is a true 36-inch clear opening, a rigid one-piece unit still has to be tilted through, and it needs room on both sides to do it. A door's nominal size is also not its clear width. A "36-inch" door clears less than 36 inches once it is open at 90 degrees, so measure it instead of trusting the label. When the numbers are within an inch or two, a multi-piece unit removes the guesswork.

Door planning for curbless showers

This is the part most guides skip. A curbless or roll-in shower exists so you can move in without stepping over anything. The bathroom door matters just as much.

• The opening should clear a person using a walker or wheelchair, plus a helper if you need one.

• Do not add a threshold at the bathroom door that a wheelchair cannot roll over. The 2010 ADA Standards (section 404.2.5) limit door thresholds to 1/2 inch in new construction and 3/4 inch in existing buildings, with beveled edges.

• The ADA calls for a doorway clear width of at least 32 inches (404.2.3), and a 36-inch minimum for accessible routes (403.5.1) that may narrow to 32 inches for up to 24 inches at a doorway. For a bathroom you plan to live in for decades, 36 inches is a comfortable target.

• A curbless unit often calls for a taller door or a wider opening than the old shower had. Plan that with your contractor before you order the stall.

Cases that need extra care

• Basements and second floors. Stairs plus turns are where one-piece units fail first. Go multi-piece.

• Mobile and manufactured homes. Doors and halls are narrower than in site-built houses. Measure and send photos.

• Apartment and condo buildings. Elevators and landings have limits. Ask building management for the elevator door width and cab depth.

• Removing a wall or window. Some builders open an exterior wall to set a one-piece stall and close it back up. It can work, but it adds carpentry and repair work that a multi-piece unit avoids.

Before you order

1. Write down the narrowest door, hall and turn on the route.

2. Choose multi-piece if any one of them is tighter than the stall's widest piece, or if you are not sure.

3. Confirm the unit's outside dimensions and its piece sizes on the product page or spec sheet.

4. Confirm freight: who unloads the crate, whether you need a liftgate, and where it will sit until install.

5. Send us a photo of the path if you want a second pair of eyes. We will say so honestly if a unit will not work.

Questions we hear

Will a one-piece shower fit through a standard bathroom door?

Usually not in a finished house. One-piece stalls are molded as a single unit, so they are wider than most doorways once you add the turn into the room. They suit new construction or a room opened to the outside. For a remodel, a multi-piece shower is the safer choice.

What door width do I need for a multi-piece shower?

It depends on the unit. Some of our multi-piece showers list "fits 30-inch doorways" on the product page. Check the page for your model, then measure the clear opening with the door open to 90 degrees, and call us if you are close.

Can I return a shower that does not fit through my door?

Made-Upon-Order showers cannot be returned, so confirm the fit before you order. Measure the delivery path, send us photos, or call 877-392-2531 and we will check the unit's piece sizes against your measurements.

How wide does the doorway need to be for a wheelchair?

The 2010 ADA Standards set a minimum 32-inch clear width for a doorway (section 404.2.3). Many people choose a 36-inch opening in their own home for easier turning and helper space. The ADA applies to public and commercial buildings; in a private home it is a useful guide.

Can I add a threshold at the bathroom door with a curbless shower?

Keep it as low as you can. The 2010 ADA Standards limit door thresholds to 1/2 inch in new construction and 3/4 inch in existing buildings, beveled at the edges. A taller threshold at the door defeats the purpose of a curbless shower.
