Lay‑Z‑Spa are the most energy‑efficient inflatable hot tubs
All Lay‑Z‑Spa hot tubs come with a range of highly beneficial energy‑efficient features, meticulously crafted materials, and insulating accessories as standard and at no extra cost which all contribute toward Lay‑Z‑Spa hot tubs being proven to be the most energy‑efficient inflatable hot tubs on the market.
We're continuously developing our technology, construction and materials to expand our range of energy-efficient hot tubs for you to have even more affordable luxury.
Testing & results
Energy‑efficient inflatable hot tubs
An independent study of comparable products by comparable brands (by SGS Laboratories) found that Lay‑Z‑Spa hot tubs heat faster, use less energy to maintain a certain temperature, and are better at keeping the heat in and are therefore the most energy‑efficient inflatable hot tubs.
Laboratory tests & results* showed that:
- Lay‑Z‑Spa hot tubs use less energy and are faster to heat the water to 40°C.
- Lay‑Z‑Spa hot tubs use less energy to heat the water when the massage system is on.
- Lay‑Z‑Spa hot tubs use less energy to maintain temperature (tested over 8 hours).
- Lay‑Z‑Spa hot tubs offer significantly better insulation. When not heating, the water temperature drops faster in competitor hot tubs.
- Lay‑Z‑Spa hot tubs overall use less energy and will in the long‑run cost less to run.

What makes every Lay-Z-Spa energy efficient?
Out of the box, without any additional purchases, every Lay-Z-Spa has a range of energy-efficient features as follows:
Lay‑Z‑Spa hot tubs are more energy‑efficient than other inflatable hot tubs because they include an insulating lid with a clip‑on top cover as standard. This helps reduce the heat loss from the water's surface where most others would be exposed to the elements.
Lay‑Z‑Spa’s advanced heating system, like a home central heating system, will actually stop heating when it reaches its set temperature. Only once the temperature drops a few degrees will it then turn on again. This means it is only heating when it needs to, making it a beneficial energy‑efficient feature that helps cut down those energy costs
The Beam and Drop Stitch construction of our hot tubs is complemented with the Lay‑Z‑Spa TriTech® material. Our premium reinforced material is used on all our hot tubs and offers superior strength and better insulation.
The Power Saving Timer helps reduce any unnecessary energy consumption such as heating your water when you don’t need to. You can program the pump to start and stop heating when you want and set your desired temperature too.
This pioneering hot tub technology means that a Lay‑Z‑Spa hot tub can be safely kept outside all year round without the need to have a constant heat source in the water. The energy‑efficient feature automatically detects when the temperature drops below 6°C and then switches on to heat your water up to 10°C.
The heavily padded, thick cushioned base of Lay‑Z‑Spa hot tubs is there for a comfortable experience but also offers an additional insulating barrier between the hot tub and the floor. Not all inflatable hot tubs on the market have a base like this.
Even more energy-efficient hot tubs
Our new EnergySense® hot tubs are up to 40% more energy efficient than a regular inflatable hot tub and our ThermaCore™ foam hot tubs are up to 60% more energy efficient than regular inflatable.
Lay-Z-Spa energy efficiency FAQs
Are all Lay-Z-Spa hot tubs energy-efficient?
All Lay-Z-Spa hot tubs, as standard, are more energy efficient that other inflatable hot tubs on the market.
We also have a range of inflatable hot tubs with integrated thermal insulation , called EnergySense®, making them up to 40% more energy efficient than a regular inflatable hot tub.
You can also explore our range of non-inflatable rigid foam ThermaCore™ hot tubs that are up to 60% more energy-efficient than an inflatable.
How can I make my Lay-Z-Spa more energy-efficient?
There are a few simple tips and tricks to making your Lay-Z-Spa more energy-efficient.
From using one of our award-winning thermal covers, to regulating when you use your heater depending on frequency of use, you can find all the advice in this article.
Why don't you provide a Thermal Cover with all hot tubs?
Because this would significantly increase the price of every Lay-Z-Spa hot tub and not everyone wants a thermal cover.
Do Lay-Z-Spa hot tubs cost less to run?
Because our hot tubs have been tested against other leading brand hot tubs and found to be more energy-efficient, we're positive a Lay-Z-Spa is cheaper to run than other inflatable hot tubs.
