Hot tub features to consider


Hot tub prices range from less expensive portable spas to eight and 10-person acrylic tubs. In addition, items such as tub surrounds, stairs, decking and even landscaping and lighting can add to cost. Price is highly dependent on brand, size and options, so shopping around is a good idea.

  • Low: Portable spas generally fall into this category. They can be collapsed and moved, and they don't require many of the extras of a more permanent spa, such as decking.
  • Medium: Smaller two to four-person hot tubs will run in the medium range of pricing. Among these, unicast spas are less expensive than a traditional acrylic hot tub.
  • High: The larger six to 10 or more person tubs and more specialized models, such as swim spas, will come in on the high end. The more jets and features that are added, the higher the cost will be.

Water filtration

There are several types of water filtration systems used to keep a hot tub clean and clear. The choice depends on a combination of cost, maintenance requirements and water-feel preference.

  • Salt system: Salt systems use chemistry to produce the needed chlorine to kill germs. Many prefer this method to adding chlorine or bromine tablets to the water and say that the water feels softer and silkier with a salt system.
  • Ozone system: Ozone works in combination with chlorine and bromine to kill germs and bacteria. In addition, ozone breaks down residues of soap, shampoo and makeup that find their way into the water.
  • UV-C system: A relatively new player in the hot tub filtration market, this method uses a high-intensity UV germicidal light ray to kill germs.

Seating options

Hot tub seating is one of the most important things to consider when purchasing a unit. Depending on how the hot tub will be used, whether for relaxation, therapy or family fun, different types of seating options will make the experience more pleasurable.

  • Lounge: Lounge seating allows for lying nearly vertical in the water, creating an almost weightless feeling. Lounge seats are for those who are seeking a relaxing experience.
  • Therapy: These seats provide extra massage points, usually at the neck, back and shoulders. Jets are usually strong for a deep-tissue massage.
  • Cool-down: Cool-down seats allow the body to remain partially out of the water. These are good for transitions in and out of the tub and usually provide leg, ankle and foot massage jets.

Jet options

When it comes to jets, more is not always better. Many hot tub manufacturers and professionals recommend having a variety of jets, with the ability to control the intensity of each.

  • Rotary jets: Also known as therapy jets, these are used for therapeutic massage and are the most versatile jets.
  • Relaxation jets: These jets have a larger and gentler flow and create a gentle and relaxing bubbling motion.
  • Pressure point jets: Pressure point jets provide a tight, intense water flow that can be used to stimulate pressure points on the body.

Ambiance options

Today's hot tubs come with some options for creating ambiance for bathers, creating an immersive experience.

  • Sound system: Hot tubs can be equipped with a sound system. Generally the speakers are built into the top lip near headrests, and they can often be controlled wirelessly via Bluetooth.
  • Decorative lighting: Lighting can be placed in the hot tub as well as along the top or outside. Lighting can change the mood from soft and relaxing to exciting and energetic.
  • Hot tub color: The color of the hot tub should not only match the environment but can be used to set the tone of bathers. From blues and browns to black, the hot tub color can set the mood in many ways.

Hot tub accessories

There is a nearly endless list of accessories available for hot tubs, from items that make owning a hot tub more convenient to those that protect the hot tub or add comfort.

  • Remote monitoring: Many home systems, such as security and heating systems, are now taking advantage of remote access. Hot tubs are no exception, and consumers can now turn the hot tub up to the desired temperature to be ready when they get home.
  • Coverall: Hot tubs come with a cover, but for tubs that are left unattended for long periods of time, such as those in a second home, a coverall can greatly increase the life of the hot tub and the tub surround.
  • Spa pillow: Say goodbye to wet, lumpy towel rests. A spa pillow will cradle the head and neck and some hot tub manufacturers offer these luxurious pillows built into the tub itself.

Types of hot tubs

Vinyl liner hot tub

Also known as soft tubs or portable tubs, these are inflatable hot tubs that are easy to move. These tubs are usually less expensive than other types but still provide the same features.

Unicast hot tub

A unicast tub consists of the tub and the surrounding cabinet which are molded as one single piece. There can be limits on size for unicast tubs.

Acrylic hot tub

This is the most popular type of hot tub. They are especially durable for outdoor use and come in a wide variety of shapes and sizes.

Swim spa hot tub

A swim spa hot tub is specifically designed for exercise with a rectangular shape and jets that create a continuous current to swim against. Some hot tub manufacturers even offer models with underwater treadmills for jogging.

Consumers who would benefit from a hot tub

Consumers needing therapy

Some consumers purchase hot tubs for health reasons, including soothing an aching back, sore muscles or for other aches and pains. Under some conditions, a health plan may contribute to the cost of a hot tub purchased for therapy use.

Consumers wanting relaxation

Consumers often purchase a hot tub for relaxation. A tub placed in a serene environment, such as in a quiet spot outdoors, is the preferred method of relaxation for some.

Consumers wanting family time

A hot tub can be a fun family activity, especially for those with small children. The effort and cost required for a pool may be too much, and a hot tub can be a nice alternative.

Consumers needing exercise

Consumers who are wanting to exercise in water but don't want the expense or commitment of a swimming or lap pool are often attracted to a swim spa.
