About Sterling

Sterling is a Kohler Company subsidiary brand (acquired by Kohler in 1984), positioned as the volume tract-builder and value-residential plumbing line. Manufactured in Wisconsin alongside Kohler products but engineered to a different price point — Sterling toilets, faucets, and showers are stocked at Home Depot and Lowes as the "Kohler-quality without the Kohler price" alternative. The toilet line includes the Stinson, Karsten, and Riverton series — primarily two-piece elongated 1.28 GPF models for new-construction spec houses.

For the complete Sterling lineup across all sub-types and capacities, see the Sterling Toilets hub.
