Start by knowing how much the kind of hot tub you want usually costs. Do some research around the different types and check your expectations are in line with your budget. You can buy a small, but good, inflatable hot tub for under $300/£300. A molded tub will be around 10 times this price though. With your needs and budget decided, read some reviews and start tracking the price for your favorite hot tubs.
Knowing that there are a few sales on throughout the year, we recommend doing your research, creating a shortlist of your favorite hot tubs, deciding how much you would be willing to pay, then snapping them up at the next sale if the price is right.
To get the best price on a top-range model, consider looking at ex-display hot tubs. There are some bargains if you keep an eye on local and online dealers.
