How to Measure for a Frameless Shower Door Enclosure in Sacramento

Thinking about installing a frameless shower door in your Sacramento home? Great choice. Frameless enclosures add a clean, modern look and instantly upgrade your bathroom. But here’s the thing—everything starts with accurate measurements. Since frameless glass is custom-cut and tempered, there’s no room for guesswork.

Let’s walk through the essentials so you can measure correctly and avoid costly mistakes.

Why Accurate Measurements Matter

Frameless shower doors don’t have bulky metal frames to hide uneven walls or sloppy dimensions. Every piece of glass is fabricated based on your exact measurements. Even being off by 1/8 of an inch can cause installation issues.

That’s one reason so many homeowners prefer frameless options. If you’re still weighing your choices, check out why so many locals choose frameless over framed shower doors in Sacramento:

Precision is everything.

Tools You’ll Need

Before you start measuring, grab the right tools:

• Steel tape measure (not cloth or plastic)
• 4-foot level
• Pencil and paper
• Painter’s tape (optional for marking)

If your home is older—common in areas like East Sacramento or Land Park—walls may not be perfectly square. A level helps you spot issues early.

Step 1: Measure the Width

Measure the shower opening at three points:

• Top
• Middle
• Bottom

Write down all three measurements. Walls are often slightly uneven, and the smallest measurement is typically used for fabrication.

Always measure from finished tile surface to finished tile surface. If tile isn’t installed yet, wait until it is. Frameless glass is measured after final surfaces are complete.

Step 2: Measure the Height

Measure from the top of the shower curb to the top of where the glass will end.

Take measurements on both the left and right sides. If they differ, use the smaller number. If you're planning a floor-to-ceiling enclosure, measure at multiple points along the ceiling line as well.

Step 3: Check for Out-of-Plumb Walls

Place your level vertically against each wall. If the bubble doesn’t sit centered, your wall isn’t perfectly straight.

Don’t panic—this is common. Sacramento homes can shift slightly over time due to soil conditions. A professional fabricator can adjust for small variations, but it’s important to identify them early.

Step 4: Measure the Shower Curb

Your curb must be level and wide enough to support hinges.

• Use your level to confirm it’s flat.
• Measure the width from the inside edge to the outside edge.
• Make sure there’s enough surface area for hardware mounting.

An uneven curb can affect how the door swings and seals.

Step 5: Plan for Hardware and Door Swing

Think about function, not just measurements.

• Which way will the door open?
• Is there enough clearance?
• Will it hit a vanity or toilet?

Most frameless doors need at least 22–24 inches of clearance for comfortable entry.

Consider Glass Options While Measuring

While planning your enclosure, it’s also a good time to think about glass upgrades.

Low-Iron Glass

When to Call a Professional

DIY measuring works in simple, square openings. But if your layout includes angles, uneven walls, or custom designs, professional measurement is strongly recommended.

A specialist will:

• Confirm all dimensions
• Check plumb and level
• Review hardware placement
• Ensure fabrication accuracy

With custom frameless glass, there’s no second chance once it’s cut.

Final Thoughts

Measuring for a frameless shower door enclosure in Sacramento isn’t complicated—but it must be precise. Take width measurements at three points, confirm height carefully, check for level and plumb, and always measure after tile is finished.

If you’re unsure, professional measurement ensures your investment fits perfectly the first time.
