This rough-in kit may be installed prior to choosing the specific trim and finish. Allows for construction or a renovation project to proceed without delays when narrowing down a design style. Trim kit is sold separately and is required to complete the unit. Save time, effort, and money on future renovation updates because there’s no need to alter plumbing behind the wall.
