Oslo AirJet™
Unwind in luxury, experience positive benefits to your health and wellbeing, and maximise your time to relax with the Lay-Z-Spa Oslo ThermaCore™ UltraFit™ AirJet™, an advanced ultra-energy-efficient rigid foam portable hot tub for up to 6 people.
The sleek Oslo ThermaCore™ UltraFit AirJet™ will leave you feeling revitalised and rejuvenated after you've experienced its enhanced AirJet™ massage with 2-level regulation. 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 60% 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 tough and durable TriTech® liner in a black marble 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 Oslo 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.
