How to prepare for your hot tub

How to prepare for a hot tub installation. OK, so you’ve done the difficult part and chosen your hot tub. So there are a couple of things you need to have in place before your hot tub can be delivered and installed.

The base for the hot tub

Hot tubs are heavy even without having water in them. A large hot tub full of water can weigh upwards of 2 tonnes, so a suitable level base is vital. The most common base is a concrete foundation. Think about the size of the pad also. It can be made to the size of the hot tub, but it may be you want a larger area to walk around the hot tub or to position the steps or other furniture. Having a clean area around the hot tub will reduce the amount of debris taken into the hot tub from bathers feet.

How thick does the concrete pad need to be

The concrete slab for the hot tub would need to be a minimum of 4 inches or 10cm’s thick, ideally 6” or 15cm. It’s a good idea to reinforce the concrete with some rebar and layer the foundation with some form of hardcore rubble for additional support. Laying a suitable concrete pad can be a DIY job, but can be labour intensive.

What about putting the hot tub on decking or a patio?

Decking is a popular choice but you must ensure your new or existing decking is able to take the additional weight of your fully filled hot tub. Reinforced decking would be required and if your decking is laid directly on the soil, extra bracing may be required. Patios are often ideal places for your new hot tub, they are already in an area of the garden which you use to entertain. It’s important to check that the patio is substantial enough to take the weight of a hot tub and is also level and flat.

Electric Supply

Your hot tub does need an electric supply and some hot tubs need ‘more electric’ than others. Generally, there are 2 electrical supply requirements. For a 13 amp plug and play hot tub a standard 3 pinned plug, just like you have on most home appliances and a suitable outdoor waterproof socket. For ‘full power’ hot tubs 20 amps or above, a cable from your electrical fuse box needs to run directly to the hot tub. Building regulations apply to this type of electrical work and this work should only be carried out by a suitably qualified and certified person. You can contact us for more details or you can discuss this with your electrician.

Water and Drainage

Hot tubs do not need to be plumbed into to any water supply. They can be filled from an ordinary garden hose. All our hot tubs are fitted with a drain attachment when a hose can be attached and run to a nearby drain for easy draining.
