While prepping our Master Spas Hot Tubs review we looked at the whole range offered to see if the brand was worthy of a place in our guide to the best hot tubs (opens in new tab)

We found the company and range very good, overall. Master Spas itself has 25 models across its four model lines, which includes its Michael Phelps Legend series - an endorsement by the legendary Olympian himself. The company also sells some of the best swim spas (opens in new tab) too, if you’re looking for something a little more athletic. Master Spas is one of the largest manufacturers of hot tubs, all built in the US, and there’s a good variety of entry-level to premium models on offer. 

Master Spas Hot Tubs review: Pricing and value 

  • Prices not listed up-front
  • A good range of relative pricing across all models

Master Spas does not list any costs, but the site does allow you to “shop by price”. The site features an undefined system of dollar signs, where tubs are ranked between two and five dollar signs to indicate how expensive they are. 

There’s a good range of price-ranked models on offer, but it’s hard to judge on price when there’s no up-front pricing. Assuming Master Spas’ system is in line with other hot tub manufacturers’ pricing ranges, Master Spas has eight entry-level models, seven mid-level models, six premium models, and four luxury models. 

This spread places more spa models in the less expensive entry- and mid-level ranges than other companies we evaluated, including Sundance Spas (opens in new tab), meaning it could be a good option for affordable tubs.

Master Spas Hot Tubs review: Models and choice 

  • Four main collections 
  • 25 models to pick from

Master Spas has four collections: Clarity, Healthy Living, Twilight and the Michael Phelps Legend Series. We liked the size varieties available in each range and at each price point. For example, the Healthy Living and Twilight lines both have models made for as few as two or as many as eight adults. There are 25 models to pick from in total, with plenty of images on the site to help you pick one that’s right for you. If none of these models pique your interest, Cal Spas Hot Tubs (opens in new tab) come in over 50 varieties. 

All of Master Spas’ products have a standard waterfall feature and light system. You can also add the Fusion Air sound system, WiFi capabilities, and mobile app compatibility to any hot tub model. Master Spas hot tubs also include a noise reduction system to decrease pump and motor vibrations by more than 150%, compared to industry standards, for a more peaceful soak. Ideal if you live in a busier neighborhood.

Master Spas Hot Tubs review: Features

  • Every tub comes with a bio-magnetic therapy seat
  • EcoPur keeps out dirt and germs

Master Spas have eight spa jet types: massage, pulsating, rotating, pinpoint, directional, cluster, whirlpool, and adjustable. Three jet types are used in the Clarity line, seven in the Healthy Living and Twilight lines, and all eight types are available for the MP Legend line. 

There are between 16 and 72 jets in each tub. Each tub comes standard with a MasterForce Bio-Magnetic Therapy seat and a StressRelief Neck and Shoulder Seat. The Bio-Magnetic seat uses magnet therapy along pressure points in your neck and shoulders. Master Spas is the only hot tub company we reviewed that uses magnet therapy in its products in addition to hydrotherapy, making it a rival for Bullfrog Spas (opens in new tab) in massage therapy. 

The StressRelief seat includes a headrest and uses downward-facing jets to relieve tension in your neck and shoulders. Master Spas also has a MasterBlaster Foot Therapy jet system available for its two higher-tier lines, which uses 28 nozzles in two jets for a reflexology-inspired foot massage.

Master Spas uses its EcoPur Charge Filtration and Ozone systems in all hot tubs, with optional upgrades to its Mast3rPur System and QuietFlo Water Care System, except in the Clarity line. The EcoPur Charge system uses copper and zinc to purify the water and filter out dirt and microorganisms. 

The Mast3rPur system combines this filter with ozone and UV-C light sanitation as well. Master Spas uses a coated wood frame, acrylic shell and icynene full-foam insulation standard in all of its spas, with the option to upgrade to a vac-formed ABS pan bottom except in the MP Legend line, where this feature is standard. 

Should you choose a Master Spas Hot Tub? 

Master Spas is a decent hot tub manufacturer that builds all products in the US. It offers a good variety of spas, especially in the entry and mid-level range, though the best features like the MasterBlaster foot massage system are only available at higher price tiers. So if you’re looking for a slightly more budget tub, this is the one to go for. For something cheaper, see our guide to the best inflatable hot tubs (opens in new tab).
