The Denali™ by Sundance Spas. It’s a classic shape. A portable round hot tub like the Denali may be the perfect solution in your landscape or the ideal size for your patio. Either way, the Denali delivers the soothing effects of Sundance® hydrotherapy in a fun package. 20 jets have been thoughtfully placed to take advantage of the round spa shape, providing you with a world of massage possibilities. Barrier-free seating makes it easy to move from seat to seat. With enough room for four adults, it’s easy to share the fun, and the powerful foot dome in this round spa makes tired feet a thing of the past.

Our traditional round spa takes its name from Denali National Park in Alaska, a beautiful reserve known for mountain peaks and snowy vistas. The Sundance Denali spa is perfectly at home at a weekend cabin or on the deck in your backyard.

If you’re checking out round hot tubs, don’t miss the Denali. Check out the Denali this weekend.

Rated 5 out of 5 by from Excellent and feels Soooo good! The Denali is perfect for my wife and I. We easily spraw out and relax and occasionally have two more people join us. It is very easy to operate and maintain. The jets are awesome, easy to aim and adjust. We bought ours in February and I'm still getting in twice a day!

Rated 5 out of 5 by from Sundance round spa I couldn't be happier. The heat goes up to 106. The light therapy is gorgeous at night. Softly switching from beautiful color to color. It's deeo, so I can swim around. I had my last Sundance for 13 years. They definitely improved the features.

Rated 3 out of 5 by from denali spa ihas bad skimmer design I have loved my sundance spa for years, but when i had to replace the old one, i am not so happy with the "redesigned" Denali. First and worst is the skimmer design. old one had a little door that floated in the opening and flapped down when it was on. New one has this crazy chimney thing on it . sometimes the chimney gets stuck and does not slide down, causing pump to suck air and stop. Even when it does retract, the smallness of the opening causes a whirlpool to form that sucks air into the pump and causes it to surge on and off. Can't be good for the pump. only if the spa is filled to literally overflowing does this action stop. I have to take off the skimmer top when i turn the jets on high. Secondly i have had 2 jets break within the first year. one is broken inside the spa, so not easily replaced. Sundance, what is going on with your QC?

Rated 4 out of 5 by from Perfect for my space and my lifestyle I've had the Denali for 3 weeks and LOVE it. It fits so nicely on the patio in the back of my townhouse - not a lot of room, so it's great. It was a breeze to get started and, with the help of my pool/spa professional, keeping the water clean & properly treated has been a snap. I will say that the jets are a bit tricky to get "just right" and it's a good thing I don't like really hard jet pressure. For those who do, this might not be the best spa for them. For me though: aaaaaaaaaaaahhhhhhhhhh.

Rated 5 out of 5 by from Perfect! I love my new Denali! I chose it for the round shape which has inspired a modern backyard transformation. It was prescribed by my doctor for relaxing my rigid muscles and cramps from Young Onset Parkinson's Disease. The action is powerful, I use it every day, I am so happy to own this! Thank you!

Rated 4 out of 5 by from Right size Owned since end of April. Have used regularly and enjoyed. Recently one of the air jets stopped working and am waiting for service from dealer
Date published: 2015-08-15
Rated 2 out of 5 by from unfriendly set up The spa is not built for ease of set up, the electrical works was difficult and time consuming to access because the panel is not hinged or otherwise easy to access. The spigot that needs to be used to drain the tub is not easily accessed either because every time you want to drain the thing you have to remove the panel. The jets have one basic speed which is also limiting. This is the second tub I've owned and I am disappointed in it. The attitude seems to be that the lower end of the line- which is still very expensive- isn't worth any bells or whistles.
