I was a Hot Springs Spa technician in high school, a Sundance spa tech my freshman year of college, and a Marquis spa tech for three years before I got an Apprenticeship with IBEW 1245.
Here is what I have to say.
Sundance tubs are ok, I would not suggest them. They are made in Chino, CA, and as far as my experience goes, the craftsmanship left much to be desired. We had several tubs that were leakers, all had poorly prepared glue joints in the plumbing. Beyond that, they often were the “frilly” brand offering all kinds of gizmos, and shiny fake marble acrylic shells that were prone to scratching. There are lots of things to break.
Hot Springs probably makes the best tubs.
Hot Springs is one of three brands owned by Watkins Corporation.
They sell Tiger river, Hot Springs, and Hotspot brand spas. The Hotspot brand is there economy line, and I would not recommend them, only because they are overpriced for what they are. On the other hand both Tiger River and Hot springs spas are excellent tubs.
Marquis are also great hot tubs.
They are manufactured in a small town near Salem Oregon. Primarily they are sold on Western side of the US. They are solid, well built, and I don’t really think you can go wrong with one.
The spa nitty grttty…
Do not buy a cheap spa! You get what you pay for.
Jacuzzi, Cal spa, and all others besides the ones listed above are a crapshoot!
Watkins has been in business for around thirty years. Simply put a hot springs tub is indestructible. As far as I know they are the only manufacturer that makes there shell out of an ABS backed thermoplastic. They are quite indestructible. Unlike other manufactures that make there shells out of a fiberglass backed acrylic sheet, which can blister and separate, the ABS backed thermoplastic that Watkins uses is the industry best. They are probably the most energy efficient tubs built, period. Watkins uses a constant filtration system, it is silent, which may be something to consider if the tub is going to be right outside a bedroom.
Marquis is a solid tub, they stand behind there product. As far as comfort and hydrotherapy goes, they are the best. They put a lot of thought into there designs. They also are very energy efficient, like Watkins/ Hot springs. They offer a wide range of tubs, you are sure to find one you will like.
Most problems that I encountered with any quality tub were customer abuse, incorrect wiring, or some sort of known defect, like a control board recall. Make sure you have your spa wired correctly. Have the dealership refer you to an electrician that they know will do the job right.
Spa size….
My advice is don’t go too small.
Marquis makes a little 170 gallon spa, the problem with it is that it is so tiny that it is almost impossible to keep the water chemistry correct, since there is so little water volume the chemistry can be thrown off easily by your body/s.
Get a least a 4 man spa. A 4 man spa will seat two Men.
Shop around, and don’t pay MSRP. They will buy the tub for Three grand, and sell it for Five.
