Unwind in luxury, relax in style and experience positive benefits to your health and wellbeing with the Lay-Z-Spa Stockholm ThermaCore UltraFit AirJet, an advanced ultra-energy-efficient rigid foam portable hot tub for up to 6 people. The square-shaped Lay-Z-Spa Stockholm will leave you feeling revitalised and rejuvenated after you've experienced its enhanced 140 AirJet massage. Thousands of tiny therapeutic bubbles are released from the outer circumference and centre of the hot tub, giving you an all-surrounding, full-body massage. This rigid foam hot tub is up to 63% more energy efficient than an inflatable hot tub due to its sturdy and durable award-winning energy-saving ThermaCore insulating foam that retains heat and reduces running costs. The thermal foam panels easily slot into a reinforced steel frame inside a tough and durable TriTech liner in a black exterior and dark blue interior. The insulating lid and EnergySense thermal top cover help with heat retention, and the power-saving timer prevents any unnecessary energy use. The Lay-Z-Spa Stockholm foam hot tub has a built-in UltraFit heater and integrated filter system, which provides better efficiency and takes up less space in your garden. And, the best part is that you can control the features using the Lay-Z-Spa WiFi app so that it is ready to relax in when you get home. You can enjoy the benefits of your Lay-Z-Spa all year round and make the most of winter hydrotherapy thanks to the pioneering Freeze Shield technology that automatically heats the water during the colder months.
