Bestbath curbed shower pans have a raised curb at the entry to keep water inside the shower. The pans are molded from gelcoat/fiberglass in center, end and square drain configurations, and many come with a matching wall system. Most curbs are about 4″ tall, measured from the bottom of the unit. Curbed pans suit standard bathrooms, remodels and multifamily projects where a barrier-free entry isn’t required.
