How to Measure & Install Irvine RV Retractable Shower Door Properly

Measure the finished mounting opening, then confirm how those measurements translate to the exact Irvine assembly. Record width at the top, middle and bottom and height at both sides, from the intended threshold mounting surface to the top mounting position. Keep all readings and note any out-of-square or out-of-plumb condition. The smallest reading alone does not establish the finished order size or required clearance; do not round dimensions or apply a generic deduction.

Record the flat mounting width and depth at both wall jambs and threshold, plus trim, ledges, handles and other obstructions. Photograph the complete opening and both mounting faces with a ruler. Check cartridge clearance, top/bottom track engagement and the travel path of the screen and lead rail against the selected assembly's dimensions.

Irvine's Slow-Roll installation instructions show the cartridge attached to a shower wall jamb with adhesive and end-cap screws, tracks engaged with the cartridge and opposite side rail, and sealing at the jambs and threshold. The bottom-track cutting allowance in that sheet is an installation detail, not an instruction to deduct that amount from the width when ordering a complete assembly. The sheet is also not a packing list establishing which fasteners or sealant accompany every configuration.

Do not assume the existing OEM sliding-glass frame is suitable for reuse. The illustrated installation does not establish compatibility with that frame or require universal removal of every existing frame. Identify its material, attachment, drainage path, flat mounting surfaces and remaining clear opening before deciding what can stay. Have the installer evaluate any removal or adaptation; no frame-reuse, demolition or offset-mount procedure is approved by this answer.

Use the current Irvine shower-screen listing to identify available configurations, and confirm the exact finished width/height, cartridge envelope, mounting details and hardware contents before ordering. A builder range, coach model or similar-looking door does not by itself confirm fit or reliable, leak-free operation.
