A plunge pool is a relatively compact rehabilitation pool with a size ranging from 7'6" x 7'6" to 7'6" x 14'. Plunge pools are designed for individuals to immerse themselves in a pool of water set at a specific temperature. These temperature variations are set to maximize the potential health benefits obtained. Some plunge pools are thermal pools set to warm temperatures while others are polar pools set to cold temperatures. These pools can come equipped with spa jets and massage hoses to provide additional therapeutic benefits.
