Hot tub spa living at home

With room for up to six adults, the Hamilton™ spa features a lounge seat and blends new technology with good old fashioned know how. Patented Fluidix™ Jets and a variety of easy-to-adjust jet faces let you decide whether you need sore muscle relief or a deep tissue release, each nestled into a variety of specialized seats to help you create your perfect backyard oasis.   The larger dimensions of this model make the series-exclusive spiral-action lounge seat perfect for long legs. And, an open footwell makes it easy to move around and socialize while still allowing tired feet to find relief with foot jets nestled in an asymmetric dome.   Get a quote on a Hamilton™ model or any spa in the full Sundance ® Spas line of high-quality, affordable hot tubs.

Rated 5 out of 5 by from Awesome Had an old spa, but this takes the cake, amazing. Upgraded to this one and have been enjoying almost nightly. It has become a main feature in my back yard on the patio. Everyone in the family loves it. This is the ultimate relaxing machine. The beauty of the stand alone spa is that you can enjoy all year round. Having multiple jet choices, and seating arrangements takes care of everyone's preferences. The waterfall is beautiful. This unit is so easy to take care of.

Rated 5 out of 5 by from Best Purchase My husband and I bought this prior to the summer to replace a hot tub that stopped working and we couldn't be happier with the investment we made in this amazing product!

Rated 5 out of 5 by from Great size for tall people! Bought the Hamilton spa one month ago hopeing it would help alleviate or lessen arthritis pain and it really does help with pain management. I use it three times per day and have went from taking 800 mg of Motrin a day to zero or 200 mg! The lounge seat is my favorite because the jets work on my neck, back, behind knees and feet.

Rated 4 out of 5 by from Nice Tub Very nice tub, but I wish I had one with an ozinator like my old tub as this chews through the chemicals.

Rated 4 out of 5 by from I love the Hamilton This is a great tub, great jet selection. Perfect for two and plenty of room for 5. Looks spectacular. I just wish there was an easy water maintenance guide, it is so confusing, there are probably lots of ways to keep your water perfect, but I just want one way and one set of instructions.

Rated 4 out of 5 by from Hamilton Model I've had this spa for approx. 1 month and so far I am pretty happy with it. I stayed right in the middle and it meets my needs. The warranty sealed the deal for me. Many similar models only had 2 years full warranty. This has the 5-year so at least I know for 5 years I am covered before needing to replace or repair any parts.
