The Hamilton outdoor hot tub is designed to provide room for family and friends without sacrificing intimacy. The Therapy Lounge is paired up for Side-by-Side Seating - both seats include SMT2 Micro Adjustable neck jets. At night, Hamilton glows with SunRay LED lighting, a new system unlike any other in an outdoor hot tub spa that includes Light Rings to illuminate the spa's diverters and air controls for ease of use.
