Description
The Harmonic H157L is a mid-sized hot tub designed to accommodate three people while maintaining a compact footprint of 58 × 83 × 34 inches (147 × 211 × 86 cm). It combines 24 hydrotherapy jets with a two-speed pump for a customizable, muscle-focused soaking experience. The tub holds approximately 180 gallons (682 liters) of water. An acrylic/fiberglass shell and treated 2×4 framework provide the structural foundation, with a choice of Sable, Coastal or Ebony cabinet finishes and seven listed acrylic shell colors. Water care features include high-efficiency filtration, an antimicrobial filter and an ozone generator with a dedicated chamber. A PolyTek cover helps protect the spa when unused. Additional equipment includes touchscreen controls, four exterior lights, four interior lights and three LED laminar jets. Electrical requirements and heater output depend on the market; confirm exact specifications and pricing with a local dealer.
