What type of base is suitable for a hot tub or spa?
All hot tubs and spas need a substantial base. The base should be solid, square, flat and level to ensure that your hot tub or spa is properly supported. Paving slabs or concrete are ideal. An existing patio is normally suitable provided it has been built soundly. A solid concrete base is more permanent and normally more expensive but it provides an excellent base especially for a larger hot tub or spa. Paving slabs are more practical and cost effective, especially for a smaller hot tub or spa at the far end of the garden. If you intend to position your hot tub or spa on timber decking you should ensure that it provides adequate support. When filled to capacity a 4 seater hot tub weighs around 1000kg or 1 tonne and a 7 seater hot tub weighs up to 2500kg or 2.5 tonnes. The base should be no smaller than the external size of the cabinet.
