What Materials Are Used to Make Hot Tubs?

Are you planning to add a hot tub to your home but aren’t sure which one you should get? Although we know hot tubs are offered in many different shapes and sizes, we might not know what materials are used to create these spas. By better understanding the materials used, you can more easily figure out which one would be best for your climate. Here’s what you need to know!

Hot Tub Shells

Hot tub shells can either be made of rotomolded plastic, vinyl or acrylic. However, one option will likely be better for your space and the weather in your area than the others. For instance, acrylic hot tubs are incredible options that maintain your desired temperature for long periods, even in below-freezing weather. Made when an acrylic material is melted over a mold and hundreds of tiny holes are created for air can escape, it is the smoothest possible result. Once cooled, resin and fibreglass are added to further strengthen the overall structure and add another layer of insulation. Although these hot tubs are heavier and cost more than those made of other materials, they are also far more reliable and durable regardless of your climate. However, if you do get a lot of snow or freezing temperatures, then an acrylic hot tub is perfect for you.  

Some hot tub shells are also created with rotomolded plastic, which is the process of melting a plastic powder into a mold. The plastic is evenly distributed and leaves a matte finish as it’s rotated. The materials used to create these hot tubs make them much less expensive than the previous option; however, with that said, they are also not nearly as durable. If you’re in an area with lots of snow, then a hot tub made of rotomolded plastic is not ideal, but if you do live somewhere warm, then is a great option. Unfortunately, because it’s lightweight, the insulation in a hot tub like this simply isn’t enough to properly withstand the cold temperatures and you will likely be paying more in electrical bills to heat your hot tub and keep it there.

Similarly, vinyl hot tubs are also more ideal for warmer climates. They are created when added to a cement frame, and are very sturdy designs but not the most insulated option. Therefore, if you’re looking for a hot tub that will withstand a Canadian winter for many years to come, ones made of acrylic material would be your best bet.

Hydropool Hot Tubs: How They’re Made

Hydropool hot tubs combine various materials to establish a shell that will withstand any temperature and is durable enough to last the long haul. These hot tubs are made when a specific mold design and an acrylic colour are chosen. After this, the acrylic material is heated as it’s pulled over the mold. Vinyl and resin are then added as the hot tub is being weighed to ensure that the fibreglass is distributed evenly. Since so many materials make up a Hydropool hot tub, with acrylic as the base, they are made to last. Although they might also be more expensive than hot tubs made of other materials, they will last for a very long time and provide energy efficiency and maximum insulation along the way. Many Hydropool hot tubs also come with the option to customize the outside of the shell and often will have easily removable panels. This makes it easy for any maintenance work and for you to have the option to change the look of it as you please. Say, for instance, you’ve had the same outside shell design for 10 years and are looking for something new and fresh. You can simply exchange the panelling out for new, more modern looks. If you have any questions regarding the options available, you can contact a Hydropool hot tub dealer for more information.
