If you’re planning to buy a new hot tub, you may want to know what the best hot tub features are or the difference between an average and a quality hot tub. These are common inquiries when it comes to buying a hot tub, especially if you are looking for a brand and model that is reliable and comfortable.
Before purchasing a hot tub, it’s important to evaluate your backyard and available space to ensure proper installation and safety.
In this article, we’ll break down the key considerations for purchasing a quality hot tub to help you make an informed purchase decision. We’ll show you how to narrow down your choices by focusing on specific features, size, and other important criteria. We’ll discuss what questions to ask a salesperson when buying a hot tub, and cover the top five key features to consider, including both the initial purchase and long-term aspects of owning a hot tub, so you can choose the right model for your space and enjoy it for many years.
While there are more than just five essential features, we’ve narrowed the range of features to those you should make top priority when searching for a hot tub. Here are the top five hot tub features to consider first:
- Jets - Quality of hydrotherapy
- Hot Tub Water system and filtration - Clean* and safe water
- Materials (and insulation) - Durability and efficiency
- Controls - Simple to use
- Seating - Fit everybody in
There is a wide range of hot tub models and features available, but focusing on these essentials will help you make the best choice.
These hot tub features are focused around getting the most out of your hot tub for a long period of time. Which is why quality is essential.
Other hot tub features such as lighting and sound systems are also important to many hot tub owners. However, in the initial stage of hot tub shopping, the standard of engineering and build quality should be at the top of your list. There will be plenty of time to opt for add-on amenities.
Energy Efficiency and Environmental Impact
When shopping for hot tubs, energy efficiency and environmental impact should be at the forefront of your decision-making process. A hot tub is a significant investment—not just in terms of the initial cost, but also in ongoing energy and maintenance expenses. Choosing an energy-efficient hot tub can help you save money over time, reduce your environmental footprint, and ensure a more enjoyable hot tub experience for years to come.
Start by looking for hot tubs with good insulation. Models featuring multiple layers of high-quality insulation, such as urethane foam, are designed to minimize heat loss and keep your water at the perfect temperature with less energy. Good insulation not only helps maintain a consistent temperature but also reduces the workload on your jet pumps and heating system, which can extend the life of your equipment and lower your utility bills.
Regular maintenance is another key factor in maximizing energy efficiency. By regularly testing and balancing your water chemistry, you can prevent scaling and corrosion that might otherwise force your pumps and heater to work harder, driving up energy costs. A well-maintained filtration system—such as a 100% No-Bypass Filtration system—ensures your water stays clean and your hot tub runs efficiently, further reducing energy consumption and supporting better water quality.
When comparing different hot tub models, don’t just focus on the sticker price. Consider the total cost of ownership, including energy usage, maintenance, and potential repairs. While some big box stores may advertise lower prices, these tubs can come with inflated prices in the long run due to higher energy consumption or lack of support. Shopping with a reputable dealer gives you access to expert advice, quality service, and a wider range of energy-efficient models that fit your budget and needs.
If you live in areas like San Francisco, where energy efficiency standards are especially important, look for hot tubs that meet or exceed local requirements such as CEC and APSP 14. Some advanced models now offer innovative features like the FreshWater Salt System, which helps maintain water quality with fewer chemicals, reducing both your environmental impact and the time you spend on regular maintenance.
As a first-time buyer, it’s wise to visit multiple dealers to compare brands, features, and prices. Ask about energy-saving technologies, insulation quality, and the long-term costs of each model. Don’t forget to consider extras like underwater lighting, jet pumps, and comfortable seating, which can enhance your hot tub experience without sacrificing efficiency.
By prioritizing energy efficiency and environmental responsibility, you’ll not only enjoy a relaxing soak in your backyard spa but also feel good knowing you’re making a smart, sustainable choice. With the right hot tub, regular maintenance, and guidance from a reputable dealer, you can create the perfect hot tub experience—one that’s fun, comfortable, and kind to both your wallet and the planet.
1. Quality of Hydrotherapy and Hot Tub Jets
While it’s easy to think that the hot tub jets just pump the water, the real importance is the balance of air and water coming through the jets. If it is just water, the quality of the hydrotherapy experience will not be as enjoyable. You will only feel true hydrotherapy when air is combined with the jet output of water. The lightness of touch that this combination provides is what ensures a soothing massage rather than shooting water, which can be very unforgiving when it is simply blasted against the body.
The size and power of jet pumps play a crucial role in the quality of the massage experience, as they influence water flow and pressure through the jets.
It’s also important to note that having more jets does not necessarily mean a better hot tub. The power and placement of the jets, along with proper jet pump sizing, are more important factors for comfort and effectiveness than simply having more jets.
Simply put, yes. When you look inside a hot tub in a showroom, it's easy to be overwhelmed by hot tubs packed full of jets. Lots of jets dotted all around the shell does not equate to a better experience. It's key to choose quality over quantity.
Rather than how many jets are featured in a hot tub, the key is where they are placed. Fewer jets in more strategic positions deliver targeted hydromassage to the parts of your body that need it the most.
When looking at the jet placement of a hot tub, you might consider what parts of your body that you want to feel the most targeted hydromassage.For example, you likely want them aligned with the soles of your feet, calf muscles, thighs, lower back, shoulders, and neck. Look at the jet position in relation to those key parts of the body. Superb hydrotherapy is not a more-is-better approach. It's about precision and jet placement. Comfort is also key when shopping for a hot tub. Fully recessed jets mean smaller jet covers. The smoother these are, and the more flush to the seat's surface, the less discomfort you'll feel when trying to relax and enjoy your hydromassage.
Every time you get into a hot tub, you want to see crystal clear water. More importantly, you want to know that the water is free of hidden germs and debris. To ensure this, you will need to do some simple maintenance. However, the better quality water care and filtration systems your hot tub is equipped with, the easier this will be for you.
When shopping for a hot tub, you want to look for pleated filters that have easy access, whether they are polyester or ceramic. Pleated filters remove debris from the water before it’s pulled through the jetting system. This is vital and helps avoid any damage to the pump and heater (in turn elongating the product’s lifespan).
It’s important to remember convenience is key when it comes to maintenance. If it’s easier to get to the filters, cleaning them is less of a chore. Additionally, having an easy-to-access drain makes draining and refilling your hot tub much simpler, which is an essential part of regular maintenance.
To ensure clean* water in your hot tub you should use a complementary system that will run alongside the hot tub’s standard filtration. These clean water systems work in conjunction with the filters and baskets already in place.
The Jacuzzi® ClearRay Active Oxygen® water system with UV-C technology and up to 5-stage ProClarity® filtration system** is one example of modern water care systems that layer multiple technologies.
Another excellent option is the all-new Jacuzzi® True Water™ system. Recently introduced by the Jacuzzi brand, the team spent three solid years researching the technology before bringing it to market. True™ uses nanotechnology to make maintaining your hot tub simpler and easier than ever—without the use of traditional cleaning agents such as bromine. With True™, almost all the chlorine has been removed, too. So you are left with clear, fresh, and beautiful water that feels good and smells good.
True™ is more effective than any other water care system the Jacuzzi team has tested. Third-party lab results show that True™ removes 99.9% of bacterial and viral contaminants without chlorine or other chemical additives***.
When it comes to automated hot tub water systems, the bottom line is they clean* more, so you can clean* less.
Do -Look for a hot tub with an automated clean water system.
Don’t -Think that adding more chemicals and incorrect dosages will keep the hot tub water clean instead of considering automatic water systems. The wrong chemical dosage can lead to skin irritations and damage components in a hot tub.
3. Hot Tub Materials and Insulation
When it comes to the build quality of a hot tub, it is quite better quality materials that are used, the better the durability of the product and the longer it will last.
Quality of the materials used goes a long way in helping with energy efficiency through insulation. You’ll want to consider both the outside and the inside of the hot tub.
The hot tub shell —
Hot tub shell options include acrylic, fiberglass and rotomolded resin. Each has its own set of pros and cons. Consider the following:
-Acrylic is durable, sturdy, and has excellent temperature retention. However, it may be more expensive than fiberglass.
-Fiberglass is more affordable but also prone to scratches and fading over the duration of use.
-Rotomolded resin has a different feel and look than acrylic. Being a single-molded unit, it is more affordable and less prone to cracks than a multi-layered acrylic counterpart.
Tip: Quality hot tub shells often consist of multi-layers of different materials. For example, Jacuzzi® Hot Tubs are made with vacuum-formed acrylic with a bonding layer that holds fast to a fiberglass layer which increases the overall strength and durability of the shell.
The reason the bonding layer is important is it helps prevent blistering and delamination of the acrylic from the fiberglass. Delamination is when the back of the acrylic loses adhesion with the layers underneath, allowing air to get in and causing the acrylic to crack. This can also cause water to leak from the hot tub. This will require a repair or the hot tub may be beyond repair, depending on the damage done.
When you start to look at the cabinet that the shell fits into, you’ll want to look at how durable it
is. remember that the cabinet serves to protect your hot tub (as well as its plumping and engineering) from the extreme cold or hot weather. It is also important to ensure the installation site can support the full weight of the hot tub when filled with water and occupants. Placing the hot tub on a level surface is essential for stability and long-term durability.
When considering seating and usage, think about how much room you need for users, as this will help determine the best hot tub size for your needs.
Acrylic Cabinets, Insulation and Covers
The cabinet of a hot tub hides the shell and engineering, but it goes beyond that. The cabinet is a protective barrier and provides added heat retention and a visual aesthetic that can be tailored to your preferences.
Modern-day acrylic cabinet sides use heat-retentive materials that may not offer total protection. But when they are used in association with insulation, material or foam, they form a dual barrier to heat loss.
Material insulation panels are pliable, easily fitted and easily removable. They are a lower-cost alternative to foam but may not provide the total coverage that foam can. Foam insulation is sprayed into the hot tub covering the base of the shell and the majority of the pipe and engineering. This forms an insulating second skin within the hot tub cabinet. You can also have the foam insulation pumped into all the cavities to reduce the area where heat can penetrate.
Most modern spas now use synthetic panels comprised of sun- and weather-resistant materials that both reduce maintenance as well as keep your spa looking great much longer than earlier wood panels.
The hot tub cover is another item to consider. Ideally, you want a foam-filled cover that is tailored fit to your chosen hot tub model. This level of insulation is on a par with what's inside the cabinet and prevents heat loss from the large surface of the hot tub water.
