Understanding when to order a shower enclosure is essential for a smooth bathroom renovation process. It is typically recommended to place the order after finalizing bathroom measurements, layout, and plumbing positions. Ordering too early may lead to sizing issues, while delays can disrupt installation timelines. Professionals often suggest confirming wall finishes, tile work, and door swing space before making a purchase decision. Lead times for manufacturing and delivery should also be considered, especially for custom enclosures. Planning ahead ensures the enclosure fits accurately and aligns with the overall construction schedule, avoiding unnecessary adjustments or project delays.
