The cost of running your inflatable hot tub depends on the size of it and how much you use it, the bigger the spa the more water there is to heat and keep warm, the more you use it the more the water drops and the more power is needed to heat it up again.

Lay-z-spa inflatable hot tub running costs

On the Lay-Z-spa site they say ‘We estimate it can cost around *£7 – £10 a week to run based on feedback we have had from our customers’.

Of course this will vary depending on your electricity supplier and how much they charge, and also the size of the spa, but this gives you a ball park figure. Inflatable hot tubs are a lot cheaper to maintain and run than a traditional fixed solid hot tub you may see with a wooden surround.

All hot tubs come with a special cover that is insulated to help keep them warm when not in use, you can also buy a floor protector to prevent the cold on the slabs or ground coming up into the spa.

Lay-Z-Spas are also thermostatically regulated, the heater will only actually switch on to top up the temperature of the water to your desired temperature, once it falls a degree or two below this as it is easier to keep warm once it drops down a little.

*Figures based Spa usage of 3 times a week for approx 25 mins with 20 mins of Lay-Z-Massage including a 5 min interval. Wind-block and cover utilised.

    I’m in the UK and have bought an inflatable hot tub, which is the American version of the UK model, which is 2kW at 230V/240V.
    Mine is 1kW at 110V/120V and comes supplied with a 5kV transformer. Total water volume is 1000 Lts.
    It takes at least 1 hr to raise the temp by 1 deg C.
    Using approx 1.7kW/h at 0.20p per unit, equates to 34p per hour.
    So total cost per 24 hours (if left on constantly) would be £8.16 per day (£57.12 per week) – extremely expensive!!
    Where do Lay Z Spa get their quotes of £10 per week running costs?

    Ours loses approximately 1 deg C per hour, and then takes 2 hours to raise the temperature by 1 deg C.
    Example: We get in the Tub at 21.00 hrs at 40 deg C – it then loses 2 deg C within 1/2 hour whilst using bubbles and obviously the lid is off (down to 38 deg C)
    I then set the timer to come on at 02.30 am for 6 hours. By 02.30 am the temperature has dropped to 33 deg C, so it will take another 12 to 14 hours to get back up to 40 deg C. VERY EXPENSIVE TO RUN.
    I’ve calculated that it’s using between 1.6 to 1.8 kW/hours @ 0.22pence/unit – that’s anywhere between £5.00 to £8.00 per day and possibly more. That’s between £35.00 to £56.00 per week – where on Earth do Lay Z Spa get £10.00 per week from?
