Hot Tub vs. Spa
If you’ve ever asked “What is a hot tub?,” you’re not alone. The terms “hot tub” and “spa” are used interchangeably. Both are basically tubs or pools of warm, relaxing water. The difference between a hot tub and a spa comes down to it being in ground vs. above ground.

Spas can be part of a larger pool and can require a higher upfront investment. Both spas and hot tubs can be a paired with a home sauna for the ultimate in relaxation.
For the purposes of this guide, "hot tub" and "spa" will be used interchangeably.

Certain size hot tubs can be heavy when filled. Make sure the outdoor foundation can support the weight. If you decide to place the hot tub on the grass, install a layer of bricks or pavers first. Or you can build a raised deck and add hot tub steps.
Tip: Remember to place the hot tub where it has access to electricity. If no outlet is available, plan to have one professionally installed.
Types of Hot Tubs
Buying a hot tub starts with deciding which type works best for your needs and space. A standard hot tub can be placed most anywhere.

Plug and Play Hot Tubs
Plug & Play hot tubs are hot tubs with a power cord included. They are usually made with an acrylic interior and a wood, metal or plastic exterior. These portable spas are self-contained and have everything they need to operate. They use about 110 volts, making them quick and easy to use. Simply plug them directly into an electrical outlet.
Inflatable Hot Tubs
Few spas are more versatile than inflatable hot tubs. Made from latex or vinyl, they are easy to install and budget-friendly. Inflatable styles have a built-in filter and pump system. They have fewer, less powerful jets, but can last up to five years with proper care.
Hot Tub Sizes
Whether you’re adding a hot tub to a small patio or a backyard corner, selecting the right size is important. A hot tub is measured by how many people it can comfortably accommodate. A 2- to 3-person hot tub is ideal for couples and families. They usually measure 3 to 4 feet high and 5 feet across. Most hold about 500 gallons of water.
Having a comfortable hot tub involves determining the width and number of seats you’ll need. If you’re tall, opt for a deeper model or a 4- to 5-person hot tub.
Large Hot Tub Sizes
If you like to entertain family and friends, a large hot tub is a great choice. A 6-to 7-person hot tub is ideal for a big backyard. Large hot tubs are usually 4 to 5 feet high and over 6 feet wide. They hold about 850 gallons of water.
Keep in mind that the space inside a hot tub can differ between models. Consider the width and depth of the seats as well as the number. You can have several seats or opt for a few lounge seats. Oversized hot tubs can be even more spacious. An 8-person hot tub or larger size can be a comfortable choice for a crowd.
Hot Tub Shapes
Hot tubs come in almost every shape. Rectangular or square hot tubs offer roomy seating and fit into many outdoor living spaces. Choose a shape based on your outdoor space limitations and the number of people you need to accommodate.
For a more space-saving option, select a spa that can be placed in a corner of a deck or patio. A triangular or corner hot tub is perfect for one or cozy for two. Other popular hot tub shapes are circular or oblong. Round hot tubs work well for smaller spaces. Many two-person hot tubs are oval-shaped for intimate seating.
