Hot Tub Brands to Avoid

When looking for the best hot tub brands, a lot of people ask which spa brands they should avoid. Here are a few things to look out for when comparing hot tub brands.

Bad Reviews

A brand with less than 4 stars out of 5 probably isn’t the best choice. In addition to looking at the overall rating, you’ll want to read a handful of hot tub reviews to see what the main complaints have been.

Bad Warranty

Double check the warranty on your hot tub before purchasing to make sure any unexpected troubles will be taken care of. Spa frames and bases should be covered for at least 5 years if not more.

No Dealers

If your hot tub is only sold online or at a big box store, be cautious before buying. A local authorized hot tub dealer is the best way to ensure you get great service before and after buying your spa. Otherwise, you may be on your own if a part needs replacing.

Hot tub Brand Comparison

In a recent survey, hot tub owners were asked which hot tub features had the biggest influence on their purchase decision when comparing hot tubs.

The results of the survey showed that these are the top 6 features that influenced hot tub purchases:

1. Jets/Therapy

2. Quality Construction

3. Energy Efficiency

4. Style

5. Comfort

6. Water Care

Because these are the most important features, it’s important to know what each hot tub company provides. Here’s a comparison of these 6 features for each hot tub brand.

1. Jets & Therapy

Because hot tubs are best known for their amazing therapeutic jets, it’s no surprise that the number one feature hot tub shoppers are looking for are quality jet massages. There is nothing more relaxing than soaking in warm water while receiving a soothing massage.

To help you find the hot tub with the best jets for you, here’s a breakdown of the jets and therapy features of each of the best hot tub brands.

Bullfrog Spas

Bullfrog Spas features the JetPak Therapy System® which allows you to select between 17 interchangeable jet massages called JetPaks, place the JetPak in the seat that fits your height, and adjust the massage power to your preferred intensity. This allows each person to completely personalize their hydrotherapy experience and target the exact muscles that need relief.

Caldera Spas

Using a holistic approach to hydrotherapy, each seat in a Caldera spa focuses on a different muscle group in the body. Known as hot tub circuit therapy, the user moves from seat to seat to massage different regions in the body.

Hot Spring

The Moto-Massage® DX jet is the latest hydrotherapy addition to the Hot Spring® spa collections. The unique massaging jet produces two streams which move up and down your back. Hot Spring also offers 10 different jet types, including rotary, directional and precision jets to create a unique spa experience for all users.


When it comes to Jacuzzi’s hydrotherapy systems, better jets are more important than more jets. Their PowerPro® jets feature Aqualibrium® technology, which provides the perfect balance of air and water, resulting in a high-flow, low-pressure massaging jet.


The Fluidix® jet system provides deep tissue relief and relaxation, working on the same pressure points targeted in reflexology. The jets simulate real massage sensations, from Shiatsu to Swedish, providing deep relaxation and tension relief.

2. Quality & Reliability

Other than finding a hot tub with the perfect jet massages, the next most important thing to hot tub owners is finding a spa they can rely on.

The best hot tubs should last 10 or more years and should require minimal maintenance and servicing.

Here’s a comparison of the quality and reliability of each of the best hot tub brands.

Bullfrog Spas

Every Bullfrog spa is constructed with the patented, wood-free EnduraFrame™ structure. Designed for durability and longevity, this ABS spa frame doesn’t deteriorate or corrode with use. All components are injection-molded, ensuring a tight, leak-free connection between the frame, plumbing and cabinet. All parts are manufactured and assembled in the U.S., guaranteed to meet the highest quality standards.

Caldera Spas

Caldera Spas uses high-quality heaters, pumps and components. Their hot tub shells are made of durable, reinforced acrylic and last for years.

Hot Spring

Hot Spring spa models also incorporate an ABS acrylic shell for improved durability and have high quality parts and components.


Jacuzzi portable spas feature high-grade, scratch-resistant acrylic shells to improve heat retention and durability. Exterior cabinets are manufactured using UV-resistant synthetic wood that doesn’t warp or degrade due to sun and weather exposure.


Sundance spas are built with a synthetic base to keep out rain and other elements. Their SunStrong® Skirt cabinets are also UV-resistant.

3. Energy Efficiency

Just as it requires energy each month to keep your refrigerator cold, you use energy to keep your hot tub warm.

However, keeping your hot tub hot shouldn’t cost an arm and a leg. Great hot tubs are well insulated and have innovative plumbing to keep energy costs down.

Here’s a comparison of the energy efficiency of each of the best hot tub brands.

Bullfrog Spas

Bullfrog Spas are ranked the most energy-efficient hot tubs in their class based on data collected by the California Energy Commission. Since Bullfrog Spas uses 90% less plumbing than traditional spas, they limit energy consumption and retain heat more efficiently. Plus, their full foam design minimizes heat loss and lowers energy costs.

Caldera Spas

Caldera Spas makes energy efficiency a priority in all its hot tub designs. From the latest insulation to the most efficient pumps, Caldera Spas® uses materials that reduce environmental impact while lowering operating costs for users. Their EnergyPro® pump operates continually at low wattage, reducing stress on the heater and lowering overall energy use.

Hot Spring

Each Hot Spring hot tub uses their Energy Smart® system to ensure maximum energy efficiency in all aspects of construction. In particular, all spas use the SilentFlo 5000® circulation pump, which continuously circulates warm water throughout the tub, consuming less energy than a 40-watt light bulb.


Jacuzzi’s high-end model, the J-LX, uses materials and components that maximize heat retention and lower energy consumption. This model exceeds energy-use standards in the industry without sacrificing the power and performance you expect from your hot tub.


Sundance Spas uses high-density insulation to prevent heat loss and minimize energy consumption. They also offer SunStrong® foam covers to increase efficiency.

4. Style & Design

When choosing a hot tub for your backyard living space, it’s important that your spa matches your style and home.

Here’s a breakdown of the styles and designs of each of the best hot tub brands.
