LAY-Z-SPA RUNNING COSTS
You won't find other portable hot tub brands displaying running costs on their websites... We're happy to show you because we know (and they know) our running costs are lower because our hot tubs are more energy efficient.
How Much Does It Cost To Run a Lay‑Z‑Spa?
Enjoying a Lay‑Z‑Spa at the weekend only can actually cost you less than a takeaway or a trip to the cinema for two.
The cost of running a Lay‑Z‑Spa hot tub depends on the type of Lay-Z-Spa you have, how it is used and your individual circumstances.
No two Lay‑Z‑Spa users are the same and many factors can affect the running costs from the size and type of Lay‑Z‑Spa and its volume of water to sheltered or unsheltered positioning and frequency of use to the fluctuation of outside temperatures and individual energy tariffs.
The running costs below are simply a guide and calculated based on the current average energy prices.
Helping you reduce hot tub running costs
We are continuously developing our products and technology to be more energy‑efficient, expanding our range of energy-efficient hot tubs and help you reduce hot tub running costs as much as we can.
For example, all Lay‑Z‑Spa hot tubs come as standard with a range of energy-saving features that you won't find on other inflatable hot tubs and our blog is a great source of advice for using your Lay‑Z‑Spa and saving on your hot tub running costs.
