Hot tubs are increasingly becoming popular today in many house holds. This is for multiple reasons. People are working longer and longer hours. A dip in the hot tub after work is extremely refreshing. Hot tubs also raise the value of a house. So in some ways buying a tub is like an investment. So you don't have to feel completely guilty when you make this luxury purchase.
Most people are unfamiliar with the
world of hot tubs though. It is not a common purpose and most people
buy one their whole entire life. This is very different from a car,
where almost everyone has one and many buy a new one every three to
five years. You won't find a two person hot tub in many homes. A 6 person hot tub would be even rarer.
A hot tub is a sizable investment. Even relatively small ones can easily cost thousands of dollars. Installing them will either take a great deal of time if you can do it yourself or a good chunk of change if you will be hiring someone. So you want something that is high quality and that will last. If you buy a poor brand you will need to often spend four figures replacing it (or you might give up entirely.)
So where to start? Visit several hot tub websites to get information. Some brands are designed to be "value". They are very priced cheaply. Some of these might be very high quality and be almost as good as a significantly more expensive one. On the other hand, some are poorly made and might need to be replaced after only several years of use. Likewise, some very high ends have fancy features and might be worth the money depending on the user. On the other hand, some brands have imaginative features that are just designed to impress people and have no actual use. In these cases a cheaper brand would get you a hot tub just as good but at a significantly lower cost.
If the brand is of decent quality, it might be worth it to purchase a refurbished hot tub. Some brands have very good quality of build and a used one is comparable to a new one. Be sure to do a decent amount of research on this.
