Ordering a DIY fixed shower screen means getting four dimensions right: width, height, glass thickness, and anchor type. Here's the full sizing guide so the panel fits the first time.

A fixed shower screen can make a walk-in shower feel open, clean, and easy to maintain, but the panel has to be sized correctly before it is fabricated. At Dulles Glass, we look at four details before recommending a screen: width, height, glass thickness, and the wall or surface where the panel will anchor.
Quick Answer: Fixed Shower Screen Size
For a 60-inch wide walk-in shower, many layouts use a fixed screen around 36-40 inches wide, leaving roughly 20-24 inches of entry clearance, and 72-76 inches tall in 3/8-inch tempered glass. Wider panels may improve splash control, but the remaining entry must still be comfortable and code-compliant. The NKBA Bath Planning Guidelines are a useful reference for entry-clearance planning.
Dulles Glass fabricates shower glass and helps homeowners size fixed shower screens for DIY or professional installation. This guide walks through each of the four measurements so your panel fits the first time.
Key Takeaways
- Standard widths: 24", 30", 36", 48", 60" in prefab; custom is available for non-standard openings.
- Standard heights: 72-76 inches; taller panels available for ceiling-height installs.
- Glass thickness: 3/8" tempered standard. 1/2" for panels wider than 60".
- Anchor type depends on wall: tile, acrylic, or fiberglass each need different hardware.
- Measure width at three heights — walls are rarely identical top to bottom.
What to Measure Before Ordering
Before ordering any fixed shower screen — prefab or custom — capture these dimensions:
- Opening width at the top — right under the ceiling (or planned top of glass).
- Opening width at the middle — 36 inches up from the threshold.
- Opening width at the bottom — just above the threshold or curb.
- Height from threshold to ceiling (or to the planned top of the glass).
- Wall plumb on the anchor side — hold a 4-foot level vertically against the wall where the panel will attach.
- Threshold profile — height of the curb, slope direction, and width of the threshold surface.
The three-width rule
Measure the opening at the top, middle, and bottom so you know the tightest point. If you are ordering a panel that spans between two fixed surfaces, size to the smallest measurement. If you are ordering a partial fixed panel, use these measurements to confirm the opening is square and that the panel you select leaves enough entry clearance.
Measure the opening width at three heights — top, middle, and bottom — to find the tightest point.
Fixed Shower Screen Width
The panel covers part of the opening, not all of it. The standard sizing rule: cover about two-thirds of the opening, leaving one-third for the walk-in entry.
| Opening width | Recommended screen width |
|---|---|
| 36" | 24" |
| 42" | 28"-30" |
| 48" | 32"-36" |
| 60" | 36"-40" |
| 72" | 48"-54" (consider return panel) |
Sizes outside standard kit widths may require custom fabrication.
A fixed panel typically covers about two-thirds of the opening, leaving the remaining third as the walk-in entry. For a deeper breakdown including shower head position and splash dynamics, see our guide on how wide a fixed shower screen should be.
Fixed Shower Screen Height
Most fixed shower screens are 72 to 76 inches tall — about 6 feet to 6 feet 4 inches. This stops the panel 4-8 inches below an 80-inch ceiling, leaving a small open band at the top for steam to exit.
Variations:
- Ceiling-height panels — for showers without a header gap. Often 78-84 inches tall for typical 80-96 inch ceilings.
- Short panels — for tub-shower combos or partial-height splash guards (54-60 inches).
- Custom heights — for showers with sloped ceilings, transom windows, or steam showers.
Glass Thickness
Frameless fixed shower screens use 3/8-inch tempered glass as the standard. The thickness matters for two reasons: structural rigidity at common widths, and visual heft. Whatever thickness you choose, a fixed shower screen should use tempered safety glass that complies with applicable safety glazing standards, including 16 CFR Part 1201.
- 3/8" (10mm) — 3/8-inch tempered glass is standard for many frameless fixed shower screens, but very wide, tall, or minimally supported panels should be reviewed against the hardware manufacturer's limits and support conditions. For panels at the upper end of those limits, the National Glass Association's Frameless Shower Enclosure Manual is a helpful guide to support requirements.
- 1/2" (12mm) — premium upgrade. Often used for wider panels, or for a more substantial look.
- 1/4" or 5/16" — only on framed or semi-framed kits. Not used on frameless installs.
Anchor Type by Wall
The hardware that attaches the panel to the wall depends on what's behind the tile or surface:
| Wall type | Anchor type | Notes |
|---|---|---|
| Tile over cement board | Standard wall anchor into stud or backing | Strongest mount. Standard for most installs. |
| Acrylic or fiberglass surround | Manufacturer-approved fastening with solid backing or through-bolting | Acrylic or fiberglass surrounds usually require manufacturer-approved fastening and solid backing or through-bolting; standard drywall anchors are not appropriate for heavy frameless glass. |
| Drywall (no tile) | Toggle bolt or stud anchor | Uncommon for showers. Verify waterproofing. |
| Solid masonry | Concrete anchor | Stone or block walls. Uses different hardware than wood-framed. |
Always follow the hardware manufacturer's instructions and confirm there is adequate structural support before drilling into tile, acrylic, fiberglass, or masonry.
Standard vs. Custom Fixed Shower Screen Sizes
If you're ordering a prefab kit, the standard widths are:
- 24 inches
- 30 inches
- 36 inches
- 48 inches
- 60 inches
Heights are usually 72, 74, or 76 inches. If your opening matches a standard width within 1/4 inch and your walls are plumb within 1/4 inch over 72 inches, a prefab kit will fit. Otherwise, custom is the safer call — custom fixed shower glass is fabricated to your ordered dimensions before tempering, so accurate final measurements are critical and a non-standard or out-of-plumb opening is never a dealbreaker.
Measurement Mistakes to Avoid
A few avoidable errors account for most fixed shower screens that arrive and don't fit:
- Measuring the width at only one height. Always capture the top, middle, and bottom — walls rarely match.
- Ordering to the average width. A panel sized to the average won't clear the tightest point. Work from the smallest reading when the panel spans between two surfaces.
- Skipping the wall-plumb check. A wall that isn't straight throws off both the fit and the seal. Hold a level on the anchor wall before ordering.
- Forgetting the threshold profile. Curb height and slope direction affect how the panel sits and where it seals.
- Ignoring entry clearance. On a partial fixed panel, confirm the open side still leaves a comfortable walk-in width.
- Assuming a standard kit fits. If any reading is off by more than 1/4 inch, custom is the safer call.

Frequently Asked Questions
What size fixed shower screen do I need?
A fixed shower screen typically covers part of the shower opening width and runs 72 to 76 inches tall. For a 60-inch wide walk-in, many layouts use a fixed screen around 36 to 40 inches wide, leaving roughly 20 to 24 inches of comfortable entry clearance. Glass is usually 3/8-inch tempered.
What measurements do I need to order a fixed shower screen?
You need opening width (at top, middle, and bottom), height from threshold to ceiling or planned top of glass, wall plumb on the anchor side, and threshold profile. Walls are rarely identical across all three width measurements, so capture all of them.
What height should a fixed shower screen be?
Standard fixed shower screen heights are 72 to 76 inches, typically stopping about 4 to 8 inches below the ceiling. Taller panels are available for ceiling-height installations or showers without an opening at the top.
What glass thickness do I need for a fixed shower screen?
3/8-inch tempered glass is standard for many frameless fixed shower screens, but very wide, tall, or minimally supported panels should be reviewed against the hardware manufacturer's limits and support conditions. Wider panels often step up to 1/2-inch tempered. 1/4-inch glass is reserved for prefab framed screens, not for frameless installations. Fixed shower screens should use tempered safety glass that complies with applicable safety glazing standards, including 16 CFR Part 1201.
How do I know if my opening fits a standard fixed shower screen kit?
Standard prefab kits come in 24, 30, 36, 48, and 60 inch widths. Measure your opening at the top, middle, and bottom. If the smallest reading matches a standard size within 1/4 inch and your walls are plumb within 1/4 inch over 72 inches, a prefab kit will fit. Otherwise, custom is the safer call.
Is it better to order a standard or custom fixed shower screen?
A standard fixed shower screen works well when the opening is square and plumb and matches kit sizing. Custom fixed shower glass is the better choice for non-standard widths, out-of-plumb walls, unusual heights, or premium finishes.
