The BlueCube C1 represents the gold standard of engineered cold exposure for high-performance longevity environments. Designed and built in the USA with a commercial-grade Line-X weatherproof shell, the C1 delivers full-body immersion in a 60" deep ergonomic tub, allowing precise cold exposure between 37°F and 70°F for advanced recovery, metabolic activation, and nervous system conditioning. Powered by a commercial EcoPlus 0.5–1 HP chiller, a high-output ozone sanitation system, and a 35-sq-ft multi-stage filtration setup, it ensures consistently clean, cold, and hygienic water with minimal maintenance. Its 14-gauge stainless-steel internal tub, insulated spa cover, and plug-and-plunge installation make it ideal for both private residences and professional longevity studios. At Lif8, we select the C1 for clients seeking medical-grade performance, extreme durability, and uncompromising cold-therapy results within a refined architectural footprint.
