We are an independent parts supplier and are not affiliated with, sponsored by, or endorsed by Watkins, Hot Spring, Caldera, Tiger River, or Solana. These names and their part numbers are used only to identify compatibility.
We offer replacement parts as alternatives to spa-branded parts. When this listing identifies a part as the same original-manufacturer replacement, it is supplied under the component manufacturer’s branding and part number, which may differ from the Watkins or spa-brand label and number. Other compatible alternatives are identified in the individual product listing. Please review the listed specifications, fitment details, and any installation differences before ordering.
