Buying Guide for the Best Hot Tubs in 2021

When you are buying a hot tub, there are several things you need to consider before you even look for a product. In this buying guide, we are first going to discuss the decisions you have to make before you start looking for the product. Each product has its own advantages and disadvantages based on how you plan to use it. Use the following tips that will help you narrow down the options you will consider when you are looking for outstanding hot tubs.

Decide the right type of hot tub

First things first, you need to decide the correct kind of hot tub. Companies sell various kinds of hot tubs like in-ground and portable hot tubs, In-ground hot tubs are typically referred to as spas as well. You will see both terms used interchangeably for the products we have mentioned in the guide.
Here is a look at the different types of hot tubs you can consider:

  • Rotationally Molded Hot Tubs: Rotationally molded hot tubs, or rotomolded hot tubs, are manufactured as a single unit. They have several features like molded seating, decorative lights, and they are more durable than the other types of hot tubs.
  • Plug-and-play Hot Tubs: Plug-and-play hot tubs are portable hot tubs that operate at 110V. They can consume up to 1,500W of energy, and you can plug them into a standard power outlet. They are easy to install and use at home.
  • Portable Hot Tubs: Portable hot tubs are usually made of acrylic material that has high durability. They are movable, but it can be a challenge moving them around without the help of a professional technician.
  • Inflatable Hot Tubs: Inflatable hot tubs are more portable than generic portable hot tubs. They are made using affordable, compact, but less sturdy materials compared to portable hot tubs.
  • Swim Spas: Swim spas include hot tub features and offer you a compact area where you can swim against a resisting current. They can also include heated jets and hydrotherapy seats.

Determine the right size and shape

Once you determine the type of hot tub you want to buy, you should choose the size. The size depends on the number of people who will use the hot tub, the kind of seating you want, and where the hot tub will be installed. Larger hot tubs are excellent for entertainment and socializing, but they take up a lot of space. Smaller hot tubs provide a more intimate experience.
There are hot tubs that can accommodate as few as two people to as many as eight. Manufacturers also make hot tubs in varying shapes. They can be square, rectangular, round, or even customized shapes. A hot tub should seamlessly add to your home. Its design should match your décor and your aesthetic.

Decide the features you want

Not all hot tubs are made the same. Consider the features individual products have to offer when you are looking to buy the hot tub. There are hot tubs with a primary focus on hydrotherapy and relaxation, and there are products that are centered more towards entertainment and lounge seating.
Many of the hot tubs let you control lights, pumps, heater components, and several other features through control panels. Some hot tubs even include sound systems, remote monitoring, and sanitation systems.

Consider the environmental impact of the hot tub

Using a hot tub, just like any appliance, will affect the environment. New hot tubs are considerably more environmentally friendly by being more energy-efficient compared to the products on the market a decade ago. Still, modern hot tubs require a significant amount of energy to work.
It is always an excellent idea to get environmentally-friendly hot tubs. Consider a product that will help you save on your energy consumption and keep the adverse effects on the environment to a minimum.

Think about the maintenance

Before you consider your options, you need to know about how much short- and long-term maintenance it will require. Hot tubs with filtration systems help keep the water clean and reduce the maintenance requirements of the product. Traditional hot tubs require manually adding sanitizers to the tub once in a while to reduce the chances of algae and other microorganisms developing in the water.
Regardless of the type of hot tub you purchase, there are a few maintenance tips that you need to consider all the time. Make sure you:

  • Deep clean the filter every month
  • Test the pH levels of the water
  • Drain the hot tub every few months and clean it before your refill the tub with fresh water
  • Replace the filter every year

Determine your budget

The cost is always going to be a critical factor when you are buying a hot tub. The size, type, shape, and features will determine the upfront cost of the hot tub. Besides the initial amount you will spend on purchasing the hot tub, there are professional installation costs and maintenance costs to consider.
Buy the best hot tub that is within your budget without compromising on the necessary features you are looking for in the product.

Consider where you will place it

Choosing the right type, size, and shape will be irrelevant if you do not have the space to accommodate the hot tub. The great place to put an above-ground hot tub is on a reinforced deck or a solid concrete slab. You can also place it under a pergola or a gazebo.
You need to select an area in your home, indoors or outdoors, where the hot tub will go. The space you use it in should have adequate room for ventilation, drainage, and you need to have access to take care of the hot tub’s maintenance requirements.

What to Look for in a Hot Tub

Now, we are going to take a look at all the things you need to look for in the finest hot tub. Understanding these aspects will play a major role in the decision you make for buying the right hot tub.

Materials

Hot tubs come in all types of materials. The exterior cabinet of the hot tub is what everybody sees. They are available in a variety of colors, patterns, textures, and materials.
When you are looking at your options, look for a product that has an exterior cabinet matching your requirements for the space it will occupy. Besides the aesthetics, you need to look for construction material that is sturdy and durable. Acrylic and rotationally molded hot tubs are popular due to their durability, but they are heavier and difficult to move around. Vinyl hot tubs cost less and are more portable, but they do not offer similar durability.

Types of Jets

Hot tubs use high-pressure jets that massage your muscles and improve blood circulation in the body. The ideal hot tub should have jets positioned strategically to provide you massages for the hydrotherapy you want. The placement of jets and the number of jets can play a significant part in your overall experience of using the hot tub.

Hot tub seats

Different hot tubs feature varying kinds of seats. You need to choose a seating style that will meet your requirements from the hot tub. Contour seats, for instance, include armrests and neck rests, which help with the massage experience. Barrie-free seats encourage better movement from one part of the hot tub to another.
Pivot seats allow you to change your position in the hot tub and adjust the type of massage you can receive. Therapeutic comfort seats provide additional massage points at the back, shoulders, and neck. Cooldown seats offer you the option of sitting slightly out of the water so you can cool down without getting out of the hot tub.

The hot tub filtration system

The filtration system of a hot tub is critical for its efficiency and ensures the smooth operation of all its systems. You need to avoid filters that are made of paper blends or cotton because you will find yourself replacing them quite often.
Suction filter systems are the top. They provide easy access for maintenance. Located on the side of the tub, they suck water in through the pump, jets, and heater. The filtration system removes visible debris from the water as well as purifying it to make the water safer to use.

Hot tub insulation

The insulation system is also vital for the hot tub. It protects some of the more delicate components of the hot tub as well as increasing its efficiency, so it uses less energy. High-quality insulation is a sign of an excellent hot tub. Hot tubs can have full foam, partial, and barrier insulation. Avoid using spray foam insulation since it can accumulate water.

The Best Hot Tub FAQs

Here are answers to some of the most frequently asked questions about hot tubs that can help you when you are making your decision to buy the hot tub for your home in 2021.

Q. Do I need to install plumbing?

A. Depending on the type of hot tub you get for your home, you might need to get plumbing installed. We have included a mixture of hot tubs in this guide. There are a few models that simply require a garden hose connection to operate without the need to install additional plumbing.

Q. How do I clean the water?

A. To make the most of your experience of using the hot tub, properly maintaining the water is a necessity. Keeping the water clean is not a big hassle. Each manufacturer gives a detailed instruction manual with their hot tubs that will contain information about how to properly maintain the water in the product while you use it. Simply follow the instructions given regarding the product in the manual for maintaining the water quality.

Q. How often do I need to clean the hot tub?

A. Most manufacturers will recommend that you drain and clean your hot tub at least four times a year. Depending on how frequently you use your spa and hot tub and how well you maintain the water, that is an ideal period between cleaning the hot tub. Most cases require only an hour to clean the hot tub. Keeping up the maintenance of the hot tub regularly will help you get the best out of it for a long time.

Q. What is hydrotherapy?

A. Hydrotherapy is the culmination of the effects that massage, buoyancy, and heat have. The heat helps to dilate blood vessels, allowing improved blood flow throughout the body. It helps a decent amount of blood flow to any damaged or sore muscle and tissue in your body. The greater blood flow to those areas of the body increases the nutrients and oxygen to those areas and helps them heal faster.
The massage provided by the jets in the hot tub helps the muscles relax and mitigates the pressure on the nerves. It also helps blood circulation throughout the body, quickening the natural healing process of the human body. The buoyancy decreases the weight of the body while it is in the water, relieving strain on joints and muscles.
Hydrotherapy is known as an effective way to relieve stress and help the body recover faster.

Q. Does a bigger pump give me a better massage in the hot tub?

A. The size of the pump does not make a difference as significant as the efficiency of the jets does when it comes to the experience of the massage in a hot tub. Several manufacturers boast about the horsepower the pumps in their hot tubs have. The horsepower for the initial thrust of the pump is higher than the operating horsepower.
The real difference is in how efficient the plumbing of the hot tub is and how effective the jets are. A lower horsepower pump that has excellent jets and efficient plumbing will give you a massage the same as a higher horsepower pump can. You need to focus on getting a comfortable massage from the hot tub rather than the strongest one. The horsepower should be enough to give you a relaxing experience.

Q. What should I know about calcium levels?

A. The water that comes from the mainline will have minerals like calcium and magnesium. Exposure to those minerals can result in a mineral buildup that can affect the performance of your hot tub in the long run. You can maintain a balance in the mineral levels of the water so that you can avoid getting cloudy water in the hot tub and reduce the chances of corrosion. Higher calcium levels might require using a softener. If the calcium levels are too low, you might need a calcium booster to get the level back up to make the water optimal for use in the hot tub.

Q. Do I need to use a water conditioner?

A. Water conditioners for hot tubs usually target the buildup of minerals in your hot tub and the pipes. Using a water conditioner will help you control the buildup and increase your hot tub’s long-term efficiency. There are several hot tub water conditioners you can choose from to get the job done.

Q. Do I need to use a pH testing kit?

A. Testing the pH level of the water is a crucial aspect of water care. It is quite simple. You need to take a small sample of water from the hot tub, dip a small pH testing strip in it and wait for a few seconds. The chart provided with the pH testing kit will show you what color of the strip will be for the corresponding pH level. If the pH levels are too high or too low, you should use corresponding products to balance out the pH levels and keep it closer to pH7.

Q. What do I need to know about the pH level?

A. The pH level of water tells you how acidic or alkaline the water is. The pH scale ranges from 0 to 14. The lower the pH level is, the more acidic the water will be. pH7 is neutral water, and if the pH goes higher than 7, the water becomes more alkaline. Low pH levels can contribute to corrosion, and higher pH levels contribute to mineral buildup.

Q. Is the hot tub installed indoors or outdoors?

A. A spa can be installed both indoors and outdoors, depending on the type of product you have. If you want to install the spa indoors, you have to consider whether it can fit through the door, and you have adequate space to accommodate it indoors.

Final Thoughts

As you might have seen in our top picks, hot tubs can differentiate by a large margin from each other. Conducting your due diligence can make a world of difference when you are looking for the best hot tub. We hope that between the guide and the reviews, you will be able to find the perfect hot tub for your home.
