Measure finished width
Measure left to right where the shower pan will sit. Check the back, middle, and front of the opening if the walls may be out of square, then note the smallest usable finished width.

How To Measure For A Custom Shower Pan
Use this guide before choosing a shower pan collection or sending details for review. The right measurements help LuxaBath confirm finished pan size, drain placement, curb layout, flange sides, and freight details before production.
Finished widthLeft wall to right wall at the finished shower pan location.
Finished depthBack wall to the front edge, curb face, or entry line.
Drain centerlinesDrain center from the back wall and from one side wall.
Curb and flange sidesWhich edges need a curb, entry, wall flange, or open side.
Measure the finished opening
Start With The Exact Space The Pan Needs To Fit
A custom Corian shower pan is reviewed from finished dimensions, not a rough guess. Measure the actual space the pan will occupy after framing, wall board, waterproofing, and wall panel plans are understood.
If the project is already drawn, send the plan. If you are measuring in the room, write down each number in inches and take photos of the opening, drain, walls, and entry side before starting the builder.
Core numbers
The Builder Needs Four Main Measurements
Width, depth, drain from back wall, and drain from side wall are the numbers that drive the pan layout. Curb and flange selections tell the shop which edges meet walls and which edge is the entry.

Step by step
How To Measure A Custom Shower Pan
Measure finished depth
Measure from the back wall to the front edge of the pan, curb line, or entry side. Note whether the front edge is a curb, a low entry, or an open side.
Locate the drain center
Measure to the center of the drain from the back wall. Then measure to the drain center from the left or right wall and record which wall you used.
Mark curb and flange sides
Identify which sides are against walls, which side is the entry, and where curbs or flanges are needed. This helps LuxaBath review how the pan connects to walls or shower panels.
Note wall and jobsite conditions
Write down out-of-square walls, unusual framing, benches, low curb needs, nearby glass, existing plumbing constraints, and whether the project is remodel or new construction.
Take photos or send plans
Photos and drawings make review easier. Include the full shower opening, drain location, entry side, wall corners, and any existing conditions that affect fabrication.

Questions
Custom Shower Pan Measuring FAQ
Should I measure rough framing or finished shower pan size?
Use the finished shower pan size whenever possible. If only rough framing is available, note that clearly so LuxaBath can review wall material, panel thickness, and final fit before production.
Where do I measure drain placement from?
Measure to the center of the drain from the back wall, then measure to the center of the drain from one side wall. Label whether the side measurement comes from the left wall or right wall.
What if my walls are out of square?
Measure the opening in more than one place and note the smallest usable dimension. Add photos or drawings so LuxaBath can review the condition before production.
Do I need to know curb and flange sides?
Yes. The builder asks which sides need curb, entry, flange, or wall conditions because those details affect how the custom shower pan is fabricated and installed.
Can I send plans instead of measuring everything online?
Yes. If the project has drawings, photos, unusual conditions, or multiple custom pieces, send plans, photos, or notes through the contact page and LuxaBath can review the project before production.
