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.
An alternative hot tub pad
A modern alternative is the Smart Deck from Leisure Concepts. Smart Deck is an easy to install base, which just requires the area to be flat and level and no other special preparation is required. Designed especially for hot tubs it is practical and durable but unlike other bases, it is totally portable. So if you ever decide on a better location for your hot tub or if you move home and intend on taking your hot tub with you, you can move your base with ease. Another great feature is that if you ever want to extend your base to cater for a tub side seating area or simply to create more room around your hot tub, then you can easily add on additional Smart Deck as and when required. If you purchase your Smart Deck with us when your purchase your hot tub, we will lay the Smart Deck for you on the day of delivery.
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.
