How much does it cost to install a hot tub?
A hot tub's real cost is the tub plus a solid base and a dedicated electrical supply. Get an indicative figure below.
What a hot tub install needs
- 1A load-bearing base
Filled and occupied, a hot tub is very heavy — it needs a reinforced slab, paving or a rated deck, not just soft ground.
- 2Electrical supply
Most hard tubs need a dedicated outdoor electrical circuit (often hard-wired) installed by a qualified electrician.
- 3Running costs
Heating, filtration and chemicals are an ongoing cost — factor them in, especially for a rental or holiday-let feature.
A hot tub is a strong feature for a holiday let or a premium rental, where it can command higher nightly rates. For a standard sale it's a personal-taste item — and the base and power supply, not the tub, are the parts people forget to budget.

Do hot tubs need special wiring?+
Most hard hot tubs need a dedicated outdoor electrical circuit, usually hard-wired with the correct protection by a qualified electrician — not a normal extension lead. Entry-level plug-in models are the exception.
