The Lay-Z-Spa Oslo ThermaCore™ UltraFit™ AirJet™ is a premium rigid foam hot tub for up to 6 people, available exclusively through Lay-Z-Spa. Unlike a standard inflatable spa, the Oslo is built with solid ThermaCore™ insulating foam panels, giving it a sturdier structure and noticeably better heat retention.
An enhanced AirJet massage system releases thousands of fine therapeutic bubbles from both the outer circumference and centre of the tub, wrapping bathers in an all-surrounding, full-body massage rather than a single-direction jet stream.
- Rigid ThermaCore™ foam construction, up to 63% more energy efficient than a standard inflatable hot tub
- All-surrounding AirJet massage system releasing bubbles from the sides and centre
- Built-in UltraFit heater and integrated filter system for a smaller garden footprint
- Durable TriTech® liner in a black marble exterior with a dark blue interior
- Freeze Shield™ technology for automatic winter water heating
- WiFi app control so the spa is ready when you get home
- Energy Saving Bundle option includes thermal cover and ground mat
The Oslo's rigid foam build is designed for households that want the look and durability of a hard-shell spa without the premium price tag of a fully rigid model. Pairing the base unit with the Energy Saving Bundle's thermal cover and ground mat can push overall energy efficiency up to 80% higher than a standard inflatable hot tub, meaningfully cutting running costs over a full season of use.

Position the Oslo on a flat, stable surface, fill with water, and connect via the Lay-Z-Spa WiFi app to schedule heating remotely. Fit the insulating lid and EnergySense® thermal top cover between uses to retain heat, and let the built-in power-saving timer and Freeze Shield™ technology manage energy use through every season. For the Energy Saving Bundle, lay the ground mat beneath the unit first and use the thermal cover for maximum insulation.
Lay-Z-Spa is a leading name in portable hot tubs, and the Oslo ThermaCore™ range represents its move into rigid foam construction — combining the brand's established hydrotherapy performance with a sturdier, more insulated build. It's available exclusively through Lay-Z-Spa, making it a genuinely distinctive option for buyers who want more than a standard inflatable spa.
Balance the water with appropriate spa chemicals and change it regularly following manufacturer guidance. Keep the insulating lid and thermal cover fitted whenever the spa isn't in use to protect the foam panels and limit heat loss. Check the UltraFit heater's integrated filter periodically and clean or replace it as needed to maintain water quality.
