Older Bullfrog Spa Models (Essential Features)

Bullfrog Spa

The Bullfrog Spas is made by Bullfrog International, a company that has been manufacturing hot tub products since 1996.

These spas are known for their JetPak Therapy System, which allows you to customize your jetted massage.

Whether you prefer a gentle or vigorous massage, Bullfrog Spas has what you are looking for.

Listed below are the key features you should expect from an old Bullfrog spa model:

FROG @ease system

If you want to sanitize your water, you should look into the FROG @ease system for older Bullgrog spa models.

This system incorporates on-demand SmartChlor technology and mineral sanitizer. This system is only available for pre-2019 Bullfrog spa models. To use the system, simply install the atease cartridge holder into your spa’s filtration chamber.

This system features a blue Mineral Cartridge that lasts for 4 months. The cartridge comes with everything you need to refill your spa. The FROG @ease Test Strips, the FROG Jump-Start system for shocking your hot tub water, and a SmartChlor Cartridge are also included with the kit. A new Mineral Cartridge will be ready to use in four months.

Using state-of-the-art computerized controls, the Bullfrog atease system for older models offers a worry-free frame and water delivery system. This makes it easy to operate the spa and to manage all its functions from anywhere. These spas also have Bluetooth capability so you can use your phone to play your music, and you can monitor your spa’s security and temperature.

WellSpring Filtration Pump

If you’re in need of a replacement filter for an older Bullfrog spa, you can find one with a separate circulation pump on Bullfrog’s website. The PBF36 fits many models, while the older models may use the PRB50 or PWW50P3. If you’re unsure, you can always search by part number. You can also find replacement parts by brand, serial number, and model year.

During the filtration cycle, the Dedicated Filtration Pump will run eight times as long as a standard filter and will not cause any noise. The Dual Filtration System is reusable and cleanable, and the Ozone Purifier System will improve your spa’s purification capability. It also saves energy by consuming 60% less electricity than standard filtration pumps. And when you buy the WellSpring Filtration Pump, you’ll find it’s compatible with older Bullfrog spa models.

The Bullfrog Premium Water Care Package features three highly effective clean water systems, the Enhanced Ozone System (EOS) and FROG @ease, to provide a sanitization solution for your spa that uses less chlorine and chemical additives.

The EOS System is also better than standard systems and has been verified to kill 99.9% of microorganisms in hot tubs.

The FROG @ease system, designed specifically for Bullfrog spas, uses SmartChlor technology to reduce the need for shocks and other treatments.

Enhanced Ozone System

To maximize the benefits of ozone, many owners install an Enhanced Ozone System (EOS) on their spas. These systems use three parts to ensure effective ozone usage.

The Bullfrog EOS 3-part system filters out excess O-3 gas and returns clean water to the spa.

It helps to eliminate the need for chemical treatments and leaves the spa 99.9% microorganism-free.

Enhanced Ozone Systems can be installed on older Bullfrog spa models. You can also install an EOS on an existing spa. An EOS will save you money.

The Enhanced Ozone System is an optional upgrade, but the benefits are worth it. You’ll save on energy costs by using 90% less plumbing equipment than a standard spa. And, compared to a traditional spa, an EOS is much more durable thanks to its precision-molded ABS frame.

Bullfrog Spas is one of the most energy-efficient hot tubs on the market. And with a simplified plumbing system and patented JetPak technology, these spas run quietly, with minimal plumbing.

A Bullfrog spa has fewer pipes, which means less risk of leaks and less power loss. Additionally, these hot tubs are guaranteed to work reliably for years to come, so you’ll never have to worry about maintenance.

Ultra-efficient plumbing system

Compared to other hot tubs, Bullfrog Spas requires less plumbing, which means less friction and power loss.

And because the plumbing system is simplified, there are fewer holes, which means fewer leaks.

Because they also use a simpler design, the jets can be even more powerful, and the entire system works more efficiently. For this reason, Bullfrog Spas is extremely energy-efficient.

Bullfrog Spas is 100% wood-free. Other spas may use wood or metal to build their spas, which can rot or rust and leave structural cracks in the acrylic shell. A Bullfrog Spa features a z-beam construction made from polyurethane, which has the same movement properties as an acrylic shell. Moreover, the spa is guaranteed not to warp for its life.

The WellSpring filtration pump by Bullfrog Spas is designed to sanitize water without the cost or noise of a standard circulation pump.

It moves 35 gallons per minute and can push out every ounce of water through dual filters.

The filtration pump is also silent and vibration-free, requiring less energy than the standard filtration pump. As a result, a Bullfrog Spa can reduce energy consumption by 60 percent.

Compact design

The compact design of an older Bullfrog spa is a feature of many newer models.

The older models may be less compact, but they still offer plenty of room to relax and unwind. Bullfrog Spas are built with precision to ensure the highest level of safety and durability.

The enduraFrame(tm) supports are injection molded Z-beams that create a precise connection between the cabinet, shell, and base. Because the frame is built with a strong, durable design, they are able to stand up to many years of use.

The compact STIL5 is an ideal model for city dwellers and apartment residents. It has a sleek, modern design and fits through an average door. It is 5′ 8″ wide and seven feet long. It can comfortably accommodate four people and features three jetPaks for hydrotherapy. This spa is also available with a larger, more expansive STIL7, which has room for six people. However, if space is at a premium, you might want to consider a larger model.

The X8 hot tub is also available in a compact design for home use. This model is seven feet in diameter with a depth of 38″ and deep seating for eight adults. There are two versions of the X8: one with a lounger and another with deep seating for seven. The M7 is a larger version of the X8 and is also available at Bullfrog Authorized Dealers.

Comfortable design

There are many reasons to consider a Bullfrog Spa, including comfort, safety, and durability. This brand has been tested to strict safety standards, including the International Electrical Commission (IEC) and Underwriters Laboratories (UL). All products are also tested to meet or exceed the minimum safety standards set by the American National Standards Institute. Bullfrog Spas is designed for comfort and durability and is available in several sizes.

Most Bullfrog Spas are built with a durable, long-lasting foundation. The foundation is precision-molded ABS plastic and features three electrical chaseways and a retractable exterior drain. Other features of a Bullfrog Spa include an easy-to-clean rodent screen, and a whirlpool jet. The JetPak Therapy System makes the spas fully upgradable.

The STIL7 represents an exciting new design concept. This spa offers two dedicated lounges with reclining chairs for up to 8 adults. The STIL7’s open concept seating lets you enjoy a relaxing massage whether you are in an upright or reclined position.

All of these features help you relax and enjoy the time spent in the tub. Soak in its soothing waters and let the stress melt away.

Maximizing the value of old Bullfrog spa

If you are in the market for a new hot tub, there are several ways to maximize the value of your old Bullfrog spa.

The parts of your hot tub are easily replaceable, and the controls and filters are easy to replace.

Regularly sanitizing the water can also extend the life of other parts.

Changing filters or adding sanitizer can also reduce your chemical needs. Here are some tips for keeping your hot tub in tip-top shape.

Older Bullfrog spa models are often a good investment, especially if you want to upgrade to the latest features. If you are on a tight budget, you can save money by buying used.

Buying from a dealer is a good idea because dealers have a reputation to maintain and often sell multiple models.

In addition to inspecting and repairing used spas for sale, they may also be willing to install your hot tub for you if needed.


If you are looking for a new hot tub, the Bullfrog R Series is an excellent option.

These models are made to the same exacting standards as premium spas and include Bullfrog’s exclusive JetPak therapy system.

Each seat offers a different type of massage, which is perfect for relaxing with loved ones.

For a larger hot tub, you can look at the R5L model, which is perfect for couples. It features 3 JetPaks and seating for seven.
