Plunge 3.8
The Plunge 3.8 from The Little Pool Co offers the perfect balance of compact size and functional space for the ultimate plunge pool experience. Engineered with a unique non-corrosive composite exoskeleton, this pool delivers exceptional durability and flexibility that traditional fiberglass pools cannot match. At 12 feet long, the Plunge 3.8 provides room to fully stretch out while still fitting in smaller backyards, courtyards, or alongside existing pools as a dedicated cold plunge or hot soak station. Choose from four stunning designer colors: Sapphire, Evolution, Pacific, and Quartz. Customize your pool with coping and fascia boards, aluminium composite panels, or leave it nude for cantilever deck integration.
