There are a lot of views about what is the ideal hot tub and it will be different for different people, which probably explains the number of different types and sizes of hot spas that are available on the market but there are a number of things which can make the hot tub ideal for family concerned.
Certainly it is ideal to get the biggest and most expensive model and this may be the best solution but it is not necessarily the right answer. It is quite possible to get an excellent system using some of the cheaper hot tubs and making sure they fit into the right environment.

The tub needs to be the right size for the number of people that use it, so often there is only one person at a time, consider how many people will realistically use it. Sometimes the tub is arranged for several people to sit but only has special massage points in odd particular places.
This means everybody has to keep moving or single occupancy ensues. There are some good tubs manufactured for 4 people that suit most needs and with a good arrangement of seats. The type of massage and arrangements of jets is important but there are many good standard arrangements if there is any doubt ring the supplier and get a good recommendation.
The good suppliers will know the range available and will be able to advise on the best arrangement for the family's needs. Remember that it might seem a great idea to get something for all the children to enjoy but a hot tub is not recommended for young children and older children should be limited in occupancy time.
