Our Spas are the top quality in build, efficiency, durability and the easiest of spa to maintain in the market. Our customer referral rates are the highest in the business and Eco Spa is the best way to build a hot tub. We build our covers to keep the heat in, last forever and not absorb moisture. Our Shell and Cover are built from a bacteria resistant material (HDPE). The traditional hot tubs are getting better but the design of the cover and the fiberglass and acrylic are their main issues and they are not going to change those because that type of build promotes chemicals sales, cove replacements and repairs. Once you purchase an Eco Spa, the spa does the work not the consumer. We drain and fill our spas once a year, use the least amount of chemicals in the industry (less than salt water by a significant margin), are far the most efficient and the only lifetime hard cover warranty in the business.
