Standard Shower Door Sizes

Standard Shower Door Sizes: What to Know in 2026

The right shower door size affects how easily you get in and out, how well the glass keeps water inside, and how the bathroom looks. No single size fits every shower, but a few ranges cover most homes. Start with these key facts:

• A single hinged or pivot door panel is usually 22 to 36 inches wide.
• Shower doors are typically 70 to 78 inches tall, and 72 inches is the most common.
• Sliding doors fit openings of 44 to 48 inches or 56 to 60 inches.
• Tub-shower doors fit 56- to 60-inch openings and are shorter because they sit on the tub ledge.
• Measure the finished opening after tile is installed, not the framing.

Standard shower door sizes at a glance

Door Type	Typical Width	Typical Height	Best For
Hinged	24 to 36 inches (wider with a fixed panel)	72 to 80 inches	Walk-in and frameless showers
Pivot	28 to 36 inches (systems fit openings up to 48 inches)	70 to 78 inches	Mid-sized and larger bathrooms
Sliding (bypass)	44 to 48 or 56 to 60 inches	70 to 76 inches	Tub-showers and narrow bathrooms
Tub-shower sliding	56 to 60 inches	55 to 62 inches	Standard 60-inch bathtubs
Bi-fold	24 to 36 inches	70 to 76 inches	Tight spaces and narrow openings
Neo-angle	22 to 30 inch door in a 36- to 42-inch-per-side enclosure	72 to 80 inches	Corner showers
Fixed panel (walk-in)	24 to 48 inches	72 to 80 inches	Doorless and curbless showers

These are planning ranges, not universal standards. Manufacturers make many sizes outside them, so always confirm the product’s exact fit range.

What Is the Standard Size for Shower Doors?

The standard size for a shower door is 22 to 36 inches wide and 70 to 78 inches tall. That range describes a single door panel. Wider showers usually combine a door with a fixed glass panel or use a sliding system, and a door wider than 36 inches typically needs an extra panel to carry the weight.

Opening width vs. door panel vs. walk-through width

Shower door sizes get confusing because three different measurements share one name:

• Finished Opening: The distance between finished walls, measured tile to tile.
• Door Panel: The moving piece of glass, often 24 to 36 inches wide.
• Walk-Through Width: The clear space you actually step through, which is smaller than the door system.

A 60-inch sliding door, for example, fits a 60-inch opening, but the panels overlap, so you walk through about half of that. Check the manufacturer’s walk-through dimension before you buy.

Standard shower door height

Most shower doors stand 70 to 78 inches tall, and 72 inches (6 feet) is the most common. Frameless systems often run 74 to 80 inches for a taller look. Tub doors are shorter, about 55 to 62 inches, because the glass starts at the tub rim. An 8-foot ceiling leaves plenty of room above even an 80-inch door.

22- to 28-inch shower doors

These compact doors suit narrow stalls, ensuite baths, and guest bathrooms. A 22-inch clear opening is the code minimum, so a door at this size works but feels tight.

Pros

• Space-Efficient: Fits small bathrooms and narrow stalls.
• Cost-Effective: Uses less glass, so it usually costs less.
• Minimal Look: Suits compact, modern designs.

Cons

• Limited Access: A narrow entry is hard for people with mobility needs.
• Tight Fit: Entering and exiting can feel cramped.
• Poor for Shared Use: Less comfortable in busy family bathrooms.

30-inch shower doors

A 30-inch door balances space and comfort. It’s a common choice for 36-by-36-inch stalls and works in many bathroom sizes and styles.

Pros

• Balanced Size: A good compromise between saving space and easy access.
• Versatile: Fits a wide range of bathrooms and styles.
• Comfortable Entry: Easier to use than a 24-inch door.

Cons

• Moderate Space Need: Still tight for some users or luxury designs.
• Mid-Range Cost: Costs more than narrower doors.
• Standard Look: Lacks the statement feel of a larger door.

36-inch shower doors

A 36-inch door gives easy, comfortable access and works well in primary bathrooms. It’s also the widest single panel most manufacturers make before adding a fixed panel.

Pros

• Spacious Access: Comfortable entry and exit for most users.
• Upscale Look: Feels more open than a narrow door.
• Broad Appeal: Fits most residential layouts.

Cons

• Higher Cost: More glass and heavier hardware add to the price.
• Needs Clearance: The wide swing is hard in very small bathrooms.
• Can Dominate: May overpower a small room.

48-inch shower door openings

A single hinged door isn’t usually made 48 inches wide, because the glass would be too heavy. A 48-inch opening typically uses a pivot door, a hinged door plus a fixed panel, or a sliding door. This size suits spacious bathrooms and often serves as a design statement.

Pros

• Wide Access: A roomy opening supports inclusive design.
• Luxury Appeal: Works as a statement piece.
• Open Feel: Makes the shower feel larger.

Cons

• Highest Cost: More glass and hardware raise the price.
• Space Needed: Requires a large bathroom for door swing.
• Installation Demands: Heavy glass needs solid wall support.

Shower Door Sizes by Door Type

The door type you choose changes the size ranges that apply. Sliding doors suit narrow bathrooms because they don’t swing. Hinged and pivot doors need floor space for the swing. Our guide to shower door types compares them in more detail.

Sliding (bypass) shower doors

Sliding or bypass doors are popular for tub-shower combos and alcove showers. They typically fit openings of 44 to 48 inches or 56 to 60 inches and stand about 70 to 76 inches tall. Each glass panel is usually 22 to 30 inches wide, and the panels overlap on a track. They work well in narrow bathrooms where a swinging door would hit a vanity, toilet, or wall. The tradeoff is that only part of the opening is open at once.

Pivot shower doors

Pivot shower doors swing on a pivot hinge at the top and bottom, so they can open inward, outward, or both, depending on the hardware. Panels are usually 28 to 36 inches wide, and complete systems can fit openings from about 27 to 48 inches. Heights run about 70 to 78 inches. You’ll need floor clearance for the full swing, so pivot doors suit mid-sized and larger bathrooms.

Hinged shower doors

Hinged shower doors operate like a regular door, with hinges mounted on the wall or a fixed glass panel. Panels run 24 to 36 inches wide and 72 to 80 inches high. They give a wide, comfortable opening and a clean look, but they need clear space to swing. Hinged doors are common on walk-in and frameless showers.

Neo-angle shower doors

Neo-angle doors are made for corner showers with an angled front. The door panel is often 22 to 30 inches wide, and the enclosure typically measures 36 to 42 inches per side. These doors save floor space in small bathrooms while still giving a comfortable entry.

Bi-fold shower doors

Bi-fold doors fold in on themselves, which makes them a smart fix for tight bathrooms. Standard widths run about 24 to 36 inches and heights about 70 to 76 inches. Because they fold instead of swinging into the room, they can give you a wider entry where a hinged or pivot door won’t fit.

Fixed panel (walk-in) shower doors

Fixed panels, also called shower screens, are stationary glass that partly encloses a walk-in shower. Widths run about 24 to 48 inches and heights about 72 to 80 inches. They pair well with curbless and walk-in showers, keeping most water contained with an open, modern look.

Shower Door Sizes by Shower Size

Your shower’s footprint points to the door that works best. Use this chart as a starting point, then confirm with the manufacturer. Our guide to standard shower sizes covers the footprints in more detail.

Shower Size	Common Door Options	Notes
30 x 30 inches (code minimum)	22- to 28-inch hinged or pivot door	Tight; check swing and clear opening
36 x 36 inches (most common stall)	28- to 36-inch hinged or pivot door, or neo-angle in a corner	Place the door on the side with the most clearance
48 x 36 inches	Pivot door, door plus fixed panel, or 44- to 48-inch slider	A wider side gives a more open entry
60 x 30 or 60 x 32 inches (tub footprint)	56- to 60-inch slider, or 28- to 30-inch hinged door plus fixed panel	Common in tub-to-shower conversions
60 x 36 inches	Slider, or hinged door plus fixed panel	Use the 60-inch side for the entry
48 x 60 inches (walk-in)	30-inch door plus fixed glass, or fixed panel with open entry	Aim the shower head away from the opening

If you’re converting a tub, our tub-to-shower conversion guide explains how the 60-inch footprint affects your options. Keeping a tub-shower combo means choosing a shorter tub door that sits on the tub ledge.

How to Measure for a Shower Door

Accurate measurements prevent the most common ordering mistakes. Follow these steps:

1. Finish the walls first. Measure from tile to tile, not framing to framing. Tile, backer board, and waterproofing shrink the opening.
2. Measure the width at three heights. Check the bottom, middle, and top of the opening, and use the smallest number.
3. Measure the height. Go from the top of the curb (or tub ledge) to where you want the glass to end.
4. Check the walls for plumb. A level shows whether walls lean. Out-of-plumb walls need a door with a wider adjustment range.
5. Check the curb. Confirm its width and that it’s level.
6. Mark the door swing. Tape the swing arc on the floor and check it against the toilet, vanity, and bathroom door.
7. Compare to the fit range. Your smallest width must fall inside the model’s stated minimum and maximum.
8. Plan wall support. Heavy glass needs solid backing at the hinge points, so add blocking before walls are closed.

Most shower doors fit a range rather than one exact width, so check the model’s minimum and maximum. If your opening is unusual, a custom glass door can be made to your measurements.

Additional Considerations in Shower Door Sizes

A few other factors affect which size works. Check each one before you order.

Minimum width by code and accessibility

Codes set the floor for shower and door sizes, mainly for safe access:

• Door Opening: The International Residential Code requires at least a 22-inch clear finished opening into a shower.
• Shower Size: The code minimum is 900 square inches of interior area with no side under 30 inches. The NKBA recommends at least 36 by 36 inches.
• ADA Transfer Shower: Where the ADA applies, a transfer-type shower must be 36 by 36 inches with a 36-inch entry.
• ADA Roll-In Shower: A standard roll-in shower must be at least 30 by 60 inches with a 60-inch-wide entry. An alternate roll-in is 36 by 60 inches with a 36-inch entry.
• Swing Direction: NKBA guidelines call for hinged shower doors to open outward.

These are requirements for specific accessible designs, not rules every home shower must meet. Local codes vary, so confirm with your contractor or building department. For accessible layouts, see our guide to roll-in showers.

Glass thickness and frame style

Thicker glass carries more weight, so it affects hardware and the type of door you can use. All shower glass must be tempered safety glass.

Glass Thickness	Typical Use
1/4 inch	Framed doors, where the frame adds strength
5/16 inch	Semi-frameless doors and some pivot systems
3/8 inch	Standard for frameless doors
1/2 inch	Premium frameless doors and large panels

The frame style also changes the fit. Framed doors offer the most adjustment for imperfect walls. Semi-frameless doors balance a lighter look with some adjustment. Frameless doors look the sleekest but allow the least adjustment. Our guide to frameless vs. framed shower doors compares them, and black-framed showers are a popular finish choice.

Bathroom layout and door swing

Your layout limits how large a door you can use:

• Space Constraints: In smaller bathrooms, a sliding or bi-fold door often works better than a door that needs swing clearance. See our tips for a small bathroom.
• Fixture Interference: Check how the door and handle interact with the toilet, vanity, and towel bars.
• Opening Direction: Outward-swinging doors need more clearance. Inward-opening and sliding doors suit tight spaces.
• Water Control: Aim the shower head away from the opening, and place any bench or niche so it doesn’t block the door.

Our standard bathroom sizes guide shows how much room a typical layout leaves around the shower.

Common Shower Door Sizing Mistakes

Most sizing problems come from a handful of errors:

• Measuring Before Tile: Finished walls make the opening smaller than the framing.
• Assuming Door Size Equals Entry Width: A 60-inch system can leave a walk-through near 30 inches.
• Measuring in One Spot: Walls that lean or bow need three measurements.
• Ignoring Door Swing: A door can fit the opening and still hit the vanity.
• Skipping the Fit Range: Your opening must fall within the model’s minimum and maximum.
• Forgetting Wall Support: Heavy glass hinges need solid backing behind the tile.
• Calling a Shower ADA-Compliant by Door Width: Accessibility depends on the whole design.

How to Choose the Right Shower Door Size

Choose a door that fits your finished opening and works for your household. Balance practical needs with your style, and don’t forget your budget and future needs. A thoughtful choice makes the shower comfortable to use and good-looking for years.

Work through this checklist before you order:

• Measure the finished opening width at the bottom, middle, and top.
• Confirm the height from the curb or tub ledge to the top of the glass.
• Check that the walls are plumb and the curb is level.
• Tape the door swing on the floor and check clearances.
• Match the opening to the model’s minimum and maximum fit range.
• Check the walk-through width, not just the door size.
• Decide on frame style and glass thickness.
• Plan wall reinforcement before the walls are closed.

An experienced installer can confirm measurements, handle heavy glass safely, and seal the door against leaks.

Shower Door Size FAQs

Here are quick answers to common questions about shower door sizes.

What is the standard size for a shower door?

A standard shower door panel is 22 to 36 inches wide and 70 to 78 inches tall, and 72 inches is the most common height. Wider showers use sliding doors or a door plus a fixed panel.

What is the standard shower door width?

A single hinged or pivot door is typically 22 to 36 inches wide. Sliding systems fit wider openings of 44 to 48 inches or 56 to 60 inches. Doors wider than 36 inches usually need an extra panel for support.

What is the standard shower door height?

Most shower doors are 70 to 78 inches tall, and 72 inches (6 feet) is the most common. Frameless doors often reach 74 to 80 inches. Tub doors are shorter, around 55 to 62 inches.

What size shower door do I need for a 60-inch tub?

A standard 60-inch tub uses a sliding (bypass) door designed for a 56- to 60-inch opening. These tub doors are about 55 to 62 inches tall because they sit on the tub ledge.

What size door fits a 36 x 36 shower?

A 36 x 36 shower typically uses a 28- to 36-inch hinged or pivot door. Measure the finished opening, and make sure the door swing clears nearby fixtures.

What is the minimum shower door width?

The International Residential Code requires at least a 22-inch clear finished opening into a shower. A 30-inch opening is a more practical minimum, and accessible showers need 36 inches or more.

Is the shower door size the same as the opening size?

No. The finished opening, the door panel, and the walk-through width can all differ. A 60-inch sliding system fits a 60-inch opening, but the walk-through is closer to 30 inches.

Should I measure for a shower door before or after tile?

Measure after tile is installed. Finished walls reduce the opening, and ordering from framing measurements can leave you with a door that doesn’t fit.

How much does a shower door cost?

Shower door installation averages about $958 nationwide, and most homeowners pay $530 to $1,391. Frameless doors cost $1,000 to $2,500, and custom glass starts around $1,300.

Can you get a custom-size shower door?

Yes. Custom glass doors can be made to your exact measurements and suit unusual openings or older homes. They typically cost $1,300 to $2,500 or more and take longer to arrive than stock sizes.
