There are many reputable companies who build quality hot tubs and truly care about their customers. Unfortunately Cal Spas is not one of them.
The Good: They sell spas with curb appeal at a cheap price.
The Bad: Poor quality components, materials, workmanship and a terrible customer service department lead to a bad ownership experience.
Some will be very lucky that their tub will give them 5 years of trouble-free service. -Those are the lucky ones. If your not one of the lucky ones, then you will look forward to dealing with a company that has no money to honor their "industry-leading" warranty.
Bottom line: The owner and his sidekick are horrible people who yell, scream and generally treat their employees and customers like dirt.
Do yourself a favor by shopping somewhere else for your new hot tub.
