Frequently Asked Questions
What size hot tub do I need?
It depends on how you plan to use it. For couples or solo use, a 2-4 person tub is plenty and keeps running costs down. For families or entertaining, look at 5-6 person models - but measure your space first, because the external footprint is always larger than you expect. We list seating capacity and dimensions on every product page so you can compare before buying. If you are weighing up costs across sizes, our UK hot tub pricing guide breaks it all down.
Do I need an electrician to install a hot tub?
For inflatable hot tubs (like our Lay-Z-Spa and Wave Spa range), no - they plug into a standard 13A household socket and you can set them up yourself in under an hour. Rigid hot tubs and swim spas typically need a dedicated 32A or 40A supply, which must be installed by a qualified electrician. This usually costs between GBP 200 and GBP 500 depending on the distance from your consumer unit. We recommend getting an electrician quote before ordering a rigid tub so there are no surprises.
How much does it cost to run a hot tub per month?
Inflatable hot tubs typically cost between GBP 30 and GBP 50 per month in electricity, depending on how often you use them and your energy tariff. Rigid hot tubs with better insulation run between GBP 20 and GBP 40 per month because they hold heat more efficiently. The biggest factor is how well insulated the tub is and whether you keep the lid on when it is not in use.

What's the difference between inflatable and rigid hot tubs?
Inflatable hot tubs (like Wave Spa and Lay-Z-Spa) cost between GBP 300 and GBP 800, plug into a standard socket, and can be packed away when not in use - they are the best way to try hot tub ownership without a big commitment. Rigid hot tubs cost more upfront (GBP 3,000+) but offer better insulation, more powerful jets, built-in heating, and a longer lifespan. Rigid tubs also heat faster and cost less to run month-to-month because of their superior insulation. If you are not sure which is right for you, our hot tub pricing guide compares total cost of ownership across both types.
Can I use a hot tub in winter?
Yes, and many people say winter is when they enjoy their hot tub most. Both inflatable and rigid hot tubs can be used year-round in the UK. Rigid tubs handle winter better because their insulation keeps the water hot without working the heater as hard, keeping energy costs manageable. For inflatables, expect slightly higher electricity costs in colder months and longer heat-up times. A good quality thermal cover is the single most effective thing you can do to reduce heat loss - browse our hot tub accessories for covers and other essentials.
How often do I need to change the water?
For most home hot tubs, a full water change every 3-4 months is standard. Between changes, you need to maintain the water chemistry with sanitiser (chlorine or bromine), test strips, and a pH balancer - this takes about 5 minutes a few times per week. If the water starts to look cloudy or smell despite proper chemical balance, it is time for an early change. We stock all the maintenance essentials you need in our hot tub accessories collection
