Choose options









Designed for residential relaxation in a space-conscious format, the Liberty Spas LYS4000 combines four-person seating with straightforward 120V plug-and-play operation. Its 84-inch by 60-inch footprint incorporates 20 adjustable jets, double loungers, integrated water features and entertainment-focused amenities in one self-contained hot tub.
Plug-and-Play Installation
The LYS4000 operates from a 120V / 15A electrical supply. It can also be converted to 240V by a licensed electrician. Installation and electrical work must comply with the manufacturer’s instructions and applicable local requirements.
Comfort and Hydrotherapy Features
The four-person interior features double loungers, adjustable and interchangeable jets, targeted hip and foot jets and cascading waterfalls. The multi-speed pump allows the user to adjust water movement for the preferred experience.
Integrated Atmosphere
Built-in LED lighting, an illuminated waterfall, Bluetooth audio and aromatherapy provide an integrated environment without requiring separate accessories for those functions.
Water Care
The spa uses a 50-square-foot Glacier antimicrobial filter. It is also AO3P ready. Owners remain responsible for routine water testing, treatment, filter care and maintenance according to the owner’s manual.
Heating
When operated on 120V, the spa may require approximately 24–48 hours to reach full operating temperature. Actual heating time can vary with starting water temperature, ambient conditions and use of the insulated cover.

Site Preparation
Install the spa on a flat, properly reinforced surface that can support the filled spa and its occupants. The owner’s manual recommends foundation support of at least 150 pounds per square foot and identifies a four-to-six-inch concrete pad as one suitable example. Customers must review the complete owner’s manual and confirm site and electrical requirements before installation.
Residential Warranty
The manufacturer’s residential limited warranty provides five-year structural coverage and one-year coverage for the acrylic surface, equipment and plumbing, subject to its complete terms, limitations, exclusions and owner responsibilities. Coverage applies to the original retail purchaser and is nontransferable. Commercial use voids the residential warranty. Parts, travel, on-site labour, accessibility, removal, installation and transportation may be treated differently or excluded under the manufacturer’s terms.
