1 - Best Dual-Zone Hybrid - Sunrans Endless Swim Spa Pool
Having two separate sections and an overall length of over 26ft, the Endless Swim Spa Pool from Sunrans is by far the largest swim spa in this supersized hot tub roundup.
Keeping the hot tub and swim spa zones apart allows for differences in depth and water temperature, as well as allowing some users to relax at the same time as others are working out.
This is a great option for those deciding between a swim spa vs a pool. Alongside some fantastic extra features for entertaining, this pool from Sunrans really does aim to disprove the notion that "you can't please all the people all the time".
Swim Section
Powered by 5 jet pumps totaling 13HP, the 3 oversize swim jets create plenty of flow for even serious swimmers to enjoy training. Don't worry if this isn't you. For a more relaxed exercise experience, you can control the output at the touch of a button.
This part of the pool also features two massage seats with jets to soothe the neck, shoulders, back, and legs. Additional cool-down seating is also featured, allowing you to choose how deep in the water you want to be immersed.
Spa Section
The Spa section alone houses an impressive 135 massage jets and 18 air jets. The seating positions range from loungers through various ergonomically molded seats, most of which feature soft neck pillows for added comfort, and more cool-down positions. This unit is as impressive for relaxation as it is for exercising.
Options And Accessories
With extras like a waterproof HD TV, DVD player, Bluetooth sound system, and pop-up waterproof speakers, the entertainment aspect of a 12 person hot tub is definitely well catered for. You can throw in extra LED lights for a spectacular nighttime look and there's even a bar counter attachment with stools.
Aside from the fun stuff, there is a whole range of extra insulation, water care upgrades, and other equipment options to choose from. Overall, it's incredibly easy to customize the Sunrans Endless Swim Spa. Selecting the right extras prior to shipping will save money and hassle compared to making changes later.
2 - Best Compact Hybrid - Integrity Spas Big Kahuna
Most swim spa hot tub combos focus more on one aspect than the other. The Big Kahuna from Integrity Spas has plenty of room to relax or party with its 800-gallon water capacity, combined with 123 massage jets, and is primarily aimed at the hot tub market.
The swim jet system is effective enough to be enjoyable but won't necessarily give quite the same level of challenge as some other swim spas.
Massage Features
Family and friends will love soaking up the heat in this luxurious hot tub.
The innovative seating configuration includes the ultimate double lounge seat for side-by-side relaxation, in addition to 8 Hydrotherapy hot seats and two cool-down seats. Each seat has a unique configuration of stainless steel jets, making the Big Kahuna one of the best hot tubs for a large number of people to enjoy warm water therapy.
Options And Accessories
Integrity Spas love to load up their hot tubs with design features and extras. The Big Kahuna is no exception. Twin water fountains, two waterfalls, four cascades, water level LED mood lighting, and even a pair of built-in ice chests are included in the basic price. You also get advanced water care featuring an ozone mixing chamber (with a dedicated circulation pump) to help maintain clean water.
Whilst so much premium equipment is available as standard, you can also customize your experience by adding the Bluetooth surround sound system to your delivery order.
3 - Best For Exercise - Thermospas 14' Swim Spa
At the other end of the scale from the Big Kahuna, this surprisingly energy efficient swim spa from Thermospas is primarily aimed at the exercise market, making it one of the best pool alternatives. In addition to the powerful swim jet system, there's a load of extra fitness equipment you can add to make this hot tub a complete gym for the whole body.
This swim spa's dimensions allows for plenty of room for 12 people to hang out, but definitely more so in terms of enjoying the space and heat rather than the hydrotherapy. The spa only has two
dedicated massage seats, so your guests will have to take turns. That said, Thermospas use a combination of powerful jets and a touchscreen control panel to provide a great massage which is definitely worth the wait.
Training Features
In addition to the basic function offered by the swim jet and pump system, Thermospas offer a swim tether, aquatic fitness kit, swim bar, and the highly innovative FORM goggles with a Heads Up Display (HUD) showing key metrics of your workout. The swim itself is enhanced by hip jets and a buoyancy jet, which help keep swimmers in the prime position for optimal training. This is simply one of the best fitness tubs on the market.
You'll also save on running costs compared to less energy-efficient swim spas.
Options And Accessories
The Thermospas 14' Swim Spa comes with the stainless steel jet and Deluxe LED lighting packages as standard, as well as LED-lit waterfall cascade jets. The basic price covers most of what you need but extras like wifi controls, cover lifters, steps, and a heater upgrade are also available.

How To Choose The Right 12 Person Hot Tub For You
When picking the right spa, the first thing to consider is the site itself. Explore your options, as these large hot tubs vary in shape as well as size. If you have room (including extra footage to be able to access your spa), consider a dual-zone piece of equipment such as the Sunrans Endless Swim Spa which provides a really special spa experience. If you're opting for a smaller unit, think carefully about how it will be used as this will affect the best choice of models.
Once you've chosen your 12-person hot tub, remember to shop around. While hot tub financing is available and helpful, there are large variations in the purchase price, shipping and delivery costs, service contracts, etc., meaning you can save a lot by choosing the right supplier carefully before you sign.
