Yes, the MAAX Utah Series Bathtub Wall Kit is designed to be trimmed to fit your specific alcove dimensions. **Trimming Guidelines:** * **What to trim:** You can trim the side and back wall panels. **Do not** trim the corner panels. * **Overlap:** Maintain at least 1/2 inch of overlap between panels. * **Method:** Use a sharp utility knife and a straight edge to **score** the line multiple times. Do not try to cut through in one pass. Gently bend the panel to snap it.
