Prviously owned a Hot Springs Vanguard (2003, LOVED IT) but had to leave it when we sold our home as part of the deal. We went shopping for another Hot Springs but could not afford the increase in price. Looked at everything then was told Caldera was made by Hot Springs. Very well constructed in and out just like the Hot Springs tubs and well afforable. Very comfortable seating with Jets galore AND a water fall affect. Also had foot massage basin which houses the VOLCANO jet....awesome !! The only draw back is the single filter operation vs. the 4 in Hot Springs tubs. I'd like to see them incorporate this into the Caldera line. It really make a difference. I find myself chasing water quality more and having to frequently clean the filter.
