Installation Notes

This model requires an under-mount installation into a 36-inch minimum cabinet base. The self-trimming apron front allows the sink to overlap the face frame for easier installation. Support framing is required to accommodate the weight of the cast iron material. It is recommended that a licensed contractor complete the install to ensure proper structural reinforcement, plumbing alignment, and code compliance.

Application

The Whitehaven sink is designed for residential kitchen environments that require a high-capacity work area with a clean apron-front appearance. Its cast iron body and single-bowl configuration make it ideal for heavy daily use and large cookware cleanup.
