The warm, tranquil water of a hot tub is becoming more recognized as a vital backyard amenity. The company that knows this best is Watkins Manufacturing, maker of Hot Spring Spas, the number one selling brand of portable spa, and Caldera Spas, built for pure comfort, performance and style. A Masco company since 1986, Watkins has manufactured more than 750,000 spas since its inception over 30 years ago. Watkins also manufactures Tiger River, Hot Spot and Solana spas. All these brands have a common element; they are built based on Watkins’ fundamental mission to produce quality spas that are superior to the host of others on the market. Both the Hot Spring Aria spa and the Caldera Martinique spa were recently named Consumers Digest Best Buy.
