What Materials Are Used to Make Hot Tubs?

Just as hot tubs come in various makes, models, shapes and sizes, they can also be made of multiple materials. Knowing how the shell of a hot tub is created will help you better understand if it’s the right option for your climate. Here’s what you need to know about the different materials used to make a hot tub.

Hot Tub Shell Options

Hot tubs can be made of rotomolded plastic, vinyl and acrylic. Various factors come into play that dictate which option would be best for your home and the weather of your area. While some might hold up better in colder temperatures, others are not quite made to withstand extreme weather over time.

For instance, acrylic hot tubs would be ideal because they can keep the heat in and the cold out far more efficiently than other options. These hot tubs are made by melting acrylic material over a hot tub mold. To achieve the smoothest structure possible, many tiny holes are made during this process for air to escape. Once cooled down, resin and fibreglass are added as an extra layer of insulation and further strengthen the shell. These hot tubs are heavy and will likely cost more than the other options we will speak about next, but will also last the longest and be able to withstand the most extreme temperatures. If you live in an area with a lot of snow and below zero temperatures, then a hot tub made of acrylic will be your best option. Because of their extra layer of insulation, you can also depend on these hot tubs to keep their heat longer, which will actually help you with energy costs in the long run. Therefore, even though you might be paying more initially, you are investing in a hot tub that can save you money long-term and will last much longer than other hot tubs.

Another material that hot tubs are made from is rotomolded plastic. By melting a plastic powder into a mold that is constantly rotated for even distribution, this material’s much less expensive than the previously mentioned. However, the one downfall of a hot tub made of this material is that it will not be the best for cold temperatures. If you live in a warmer climate that doesn’t receive snow, then a hot tub made of this material might be perfect for your home. This is why it’s best to understand how materials are used and withstand temperatures before looking at hot tubs.

Hot tubs made of vinyl are also less expensive and are another solid option. Used alongside a cement frame, a vinyl liner creates a hot tub shell. Once again, if you’re looking for a good hot tub to add to your home and you live in a warmer climate, vinyl spas are a great option.

Hot Tub Design Options

Although there aren’t very many options for hot tub shells, there are more opportunities to customize a spa on the outside. Oftentimes, you will be provided with the chance to choose your own outside materials, designs and more. You can make the hot tub more unique to your backyard vision by choosing from different textures and colors. The cabinets of a hot tub will often include removable side panelling. This not only provides easy access to the spa for maintenance purposes but also makes it simple to change the look of your hot tub as you please.

When it comes to the insulation of a hot tub, it has to do with the materials used initially for the shell and how much added insulation a manufacturer chooses to include. Foam is used as an extra layer of protection and is either added to specific sections or throughout the entire thing for maximum insulation. This is key when it comes to living in colder climates. Not only will this protect every running part of your hot tub but also allow your hot tub’s temperature to get to its optimal temperature much quicker and stay there for longer. If you have any questions about the insulation of the hot tub you’re looking to buy, reach out to the hot tub store directly so they can provide you with this information.

Before adding a hot tub to your home, it’s a good idea to ensure you know what materials are used. In many cases, where you live will play just as significant a role in this decision as your budget will. To find just the right hot tub for you and your home, download our free buyer’s guide.
