Sterling offers 7 rv & marine toilets models in the lineup we track. This page is the Sterling-specific cut of the broader RV, Boat & Marine Toilets toilets category — same product class, narrowed to the Sterling catalog only.
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.

RV and marine toilets are a separate engineering category from residential — they operate without a sewer connection, dispose to portable holding tanks (cassettes) that you empty at dump stations, and have to function on the limited 12-volt power available in mobile applications. Brands and product lines are entirely different from residential.
