Small Hot Tubs: Do I Need a Large Hot Tub?

Small hot tubs are great for 2 people

Hot tubs, much like people, come in different shapes and sizes. When weighing on the perfect hot tub spa for your backyard, one of the crucial factors is the size and dimensions. For some, a large hot tub is the only way to go, while small hot tubs will do just fine for others.

Small hot tubs will most likely fit in most places, cost less, and are less expensive to run and maintain, but they are not always practical for larger groups. Larger hot tubs have more seating, pumps, jets, and features that can give you a better overall experience, but it’s not always the best option for your space or budget.

Get this bit right, and you can look forward to many years of bubbling bliss, get it wrong then your spa could become a white elephant with exorbitant running costs.

How Do You Know If A Hot Tub Is Large Or Small?

Well, it depends on your needs. Generally, hot tubs are classified according to the number of people they can accommodate. Spas that hold up to four people are usually considered small hot tubs, while those that can hold more than four people are considered medium or large if they can accommodate more than six people.

Another way to determine if a hot tub is small or large is through its measurements. A small hot tub typically measures between 3 and 5 feet wide, while a large hot tub can be up to 8 feet wide. The height and depth of the hot tub can also give you an indication of its size. The three most popular categories of hot tub sizes are:

Small Hot Tubs

Seating for 2 to 4 people, usually with a smaller pump and fewer jets. It is a great choice if you have limited space or want to use it with few people, usually family members. However, they have all the premium features but in a compact package.

Medium hot tubs

There is enough space to accommodate 4 to 6 people comfortably. Medium hot tubs are the most popular because they are the perfect balance of size and features. They typically have more jets than small hot tubs, making them ideal for people wanting a deeper hydro massage experience. They are suitable for small groups or families that want to invite friends to share the hydrotherapy experience.

Large hot tubs

If you have a large backyard and want to entertain many people in the hot tub, these are the best options. They have enough room for large groups of 7 or more people and offer luxurious features, such as advanced audio systems, illuminated cup holders, and multiple pumps that provide different hydrotherapy solutions. Although large hot tubs are the most luxurious, they come with a hefty price tag. Find 7 seater hot tubs here and the two hot tubs that seat 8 people here.

Things To Consider Before Buying A Small Hot Tub

1. The seating capacity

When selecting a hot tub, consider the number of people who will frequently use it. Opting for a larger hot tub designed for eight people may not be practical or efficient if only 2 or 3 people will be using it at any given time. Small hot tubs, with seating for up to 4 people, are ideal for smaller groups and understandably cost less than larger models.

Suppose you plan to use the hot tub for entertaining, such as romantic evenings with your partner or small family gatherings. In that case, a small hot tub is an ideal size for these occasions because it is intimate and cozy and still offers a lot of features.

2. Energy efficiency

Before you decide on a small hot tub, you need to consider two factors – the initial cost and the monthly running cost. Spas with superior energy efficiency quality tend to have a higher initial cost, but these models have a lower running cost and can save you money in the long run. Energy-saving features to look out for include:

  • High-density foam insulation
  • High-efficiency filtration systems
  • Programmable energy-saving filters
  • High R-Value
  • Low wattage pumps
  • LED lights
  • Insulated covers

3. Size matters

Hot tubs come in various depth ranges, and you need to determine the size that best suits your needs. Some small hot tubs are as shallow as 30 inches in depth, while others can go as deep as 43 inches. A shallow hot tub is great for a quick soak but doesn’t provide enough room for proper relaxation, especially for taller people.

A deep hot tub is ideal for tall people looking to enjoy a full-body hydro massage, and some models even include loungers to stretch your legs and get a completely immersive experience. Spas with multiple loungers also provide enough space for several people to relax and enjoy the hydrotherapy benefits.

4. Water Care

The convenience of a self-cleaning hot tub can’t be overstated. Smaller hot tubs are often designed with advanced water care technology to make maintenance easier. Look for features like automatic water filtration, oxidation systems, and chemical feeders that help keep the water clean and free of contaminants. For small hot tubs, saltwater systems are a great option as they reduce the need to add chlorine regularly.

5. Installation logistics

The installation of your hot tub should be done by a professional to ensure that everything is set up correctly and safely. If you are living in a condominium or your backyard does not have enough space for a large hot tub, then you may need to look for smaller options that can be installed inside or on a balcony. 

Many small hot tubs come with an electric plug-in feature that allows them to be used indoors. Some models also come with a mounting kit that allows them to be easily attached to the side of a building or other sturdy structures.

Some logistical considerations to help you choose the right small hot tub include:

Weight – some models may be too heavy to mount on a wall or balcony

Drainage – most models require a drain to be installed for easy water removal

Ventilation – hot tubs generate a lot of steam and need to be vented properly

Accessibility – consider how accessible the spa is for wheelchair users or the elderly if needed.

Safety – some models may require added accessories for safety, such as a high-quality locking cover.

Final thoughts

Small hot tubs are a great way to enjoy hydrotherapy benefits in a compact package. To get the most out of your hot tub experience, it’s important to choose a size and model that best suits your needs. Think about how many people will be using the hot tub, and consider your budget, too. 

When purchasing a hot tub, pay attention to features such as insulation and filtration systems that can help increase efficiency, save energy costs, and make your hot tub easier to run and maintain. Finally, look for a hot tub that has a warranty and follow the manufacturer’s guidelines to make sure you get the most out of your purchase.
