Hot tubs are a great addition for any home. They can be used for many purposes, including relaxation, socialization and to simply warm up on a cold day.
It’s easy to know the exact type of hot tub that you’re getting when purchasing a new one, as it often requires plenty of research.
However, if you acquired a second-hand hot tub or if you’ve moved into a home that already has one, then it’s not uncommon to be missing the manufacturer’s documentation. This often raises the question “What kind of hot tub do I have?”
Knowing the type of hot tub you have is important in being able to understand its features, benefits and upkeep requirements.
In the post, we’ll provide some simple steps in helping you determine what kind of hot tub you have. Knowing this information can help you enjoy it to its fullest.
Types of Hot Tubs
There are numerous types of hot tubs out there. While most offer multiple jets and seating configurations, their construction may vary significantly.
Here are a few of the most common types of hot tubs:
Acrylic Hot Tubs
These are the most common types of traditional hot tubs. They are constructed from high-quality acrylic.
Acrylic hot tubs are known for their smooth, easy-to-clean surfaces and come in various sizes and shapes. They typically have multiple jets for hydrotherapy and various seating configurations.
Fiberglass Hot Tubs
These hot tubs are made entirely of fiberglass-reinforced plastic. They are lightweight, durable, and easy to maintain. Fiberglass hot tubs are often pre-molded into specific shapes and sizes, making them a convenient choice for homeowners.
Polyethylene resin is rotationally formed using a mold. The hot tub comes out of the mold in a single piece.
The rotomolded material is often lighter weight than acrylic or fiberglass, while still providing great durability.
Custom-Built Hot Tubs
Traditional hot tubs can also be custom-built to suit specific requirements. Customization options include choosing the size, shape, materials, and features to create a hot tub that matches your preferences and fits your space perfectly.
Some traditional hot tubs are designed as small, deep pools for cold plunges. These are often used for contrast therapy, where individuals alternate between hot and cold water immersion for health benefits.
Saltwater Hot Tubs
Traditional hot tubs can be equipped with saltwater chlorination systems.
These systems use salt to generate chlorine, providing a gentler and more natural way to sanitize the water compared to traditional chemical-based sanitation.
Inflatable Hot Tubs
Inflatable hot tubs are an affordable option to add simple luxury to their home. However, they often can only be used in temperatures above 40°F.
These hot tubs are commonly constructed of vinyl material, which can be subject to damage resulting in shorter lifespan.
Hot Tub Brands
There have been many different hot tub manufacturers over the years. Here are some of the most popular:

What Kind of Hot Tub Do You Have?
In the event that you did not purchase your hot tub brand new from a retailer, you could be in a situation where you don’t actually know what type of hot tub you have.
Many hot tubs share similar design concepts involving pumps, filter, spa heater, and jets to provide a soothing environment. However, understanding the exact type of hot tub you have will allow you to take full advantage of its features to maximize comfort.
If you’re having trouble figuring out details about your hot tub, here are some steps you can take.
Examine the Brand and Model
One of the easiest ways to determine what kind of hot tub you have is by checking for any branding or labeling.
Look for a logo or nameplate on the hot tub itself, typically found near the control panel or on the exterior shell. Sometimes this information may be hidden inside the cabinet.
The nameplate will often display the manufacturer’s name and model number.
Once you know this information, you can contact the manufacturer to seek out additional details or documentation for your specific hot tub.
In the event that you can only determine the brand without model number, you can likely send a photo to the manufacturer for them to further identify the exact type.
Review the Owner’s Manual
If the owner’s manual is still available with the hot tub, it will be a valuable resource for understanding its features.
The manual may include important information about installation, operation, maintenance, and troubleshooting. If you don’t have a physical copy, many manufacturers provide digital versions of their manuals on their websites.
Measure the Size
The size and capacity of your hot tub are crucial factors to consider. Measure the dimensions of your hot tub, including its length, width, and depth.
If you know the dimensions you can then calculate the approximate volume of water that the hot tub holds. This is useful in determining the right amount of chemicals to use when balancing the water.
Review the seating configuration of the hot tub, as this will tell you how many people the hot tub is designed to accommodate. Some hot tubs may include lounger seats, captain’s chair, or cool down seats.
This information will tell you how many people the hot tub can comfortably accommodate, which is helpful when planning gatherings
Check the Features
Different hot tubs come with various features. Take note of the following:
- Jet Configuration: Count the number and types of jets in your hot tub. Some hot tubs have adjustable jets that can provide targeted hydrotherapy. Some jets may blow air.
- Heating: Find out how your hot tub heats the water. Most hot tubs use electric heaters, but some may use gas or other methods.
- Pumps: Review how many pumps the hot tub utilizes, including their horse power and whether they are single or multi-speed.
- Control Panel: Familiarize yourself with the control panel’s settings and functions. This is where you adjust the temperature, jets, and other settings.
- Filtration and Sanitization: Learn about the filtration system and any water treatment options your hot tub may have, such as ozone or saltwater chlorine generators.
- Lighting and Entertainment: Check for underwater lighting, audio systems, and other entertainment features that your hot tub might offer.
Opening up the cabinet will allow you to review the mechanical aspects of the system.
Identify the Age
Determining the age of your hot tub can also provide valuable insights. Manufacturers often update their models with new technology and design improvements.
Knowing the approximate age can help you find relevant information and replacement parts if needed.
Knowing the brand and model is often the easiest way to determine the kind of hot tub you have. With this information, you can often find manuals and other documentation to help you take full advantage of its features.
However, don’t lose hope if your hot tub doesn’t have any manufacturer identification.
Performing a careful review of your hot tub, including size, mechanical components, and seating configuration will help you determine its general type. This review can also help you determine whether the hot tub has any special sanitization components, or whether standard sanitizers –such as chlorine or bromine– can be used.
Armed with this knowledge, you can confidently care for your hot tub, ensure its longevity, and create countless relaxing moments in your personal oasis.
