Shower basins are becoming more popular. Companies are able to manufacture pre-built shower basins where most shower basins were built to size by a tile professional. Most shower basins come in an acrylic-fiberglass type material similar to tubs. There are some cast iron shower basins out there, but are a little more expensive.
As shown in the photo, Mock Plumbing installed a 60” x 30” shower basin with tile shower walls and tile floor. A sliding glass shower door was added. Great job Mock Plumbing!
