What Materials Are Used to Make Hot Tubs?

When it comes to hot tubs, there are a lot of factors that can influence which one you choose. Of course, it’s important to consider the size and shape of the spa in your decision-making process, but what about the materials used to make it? Below, we’ll take a look at some of the most popular hot tub materials and discuss the pros and cons of each.

What Are the Most Popular Hot Tub Shell Materials?

Acrylic, vinyl, and rotomolded plastic are the most popular materials used to construct hot tub shells. However, each one has its own set of benefits and possible drawbacks, so it’s important to know what you’re looking for before deciding.

Acrylic is a strong, durable material that is easy to clean and maintain. It’s also resistant to UV rays, so it won’t fade in the sun. In addition, it can easily be moulded into different shapes. Creating acrylic hot tubs involves melting the material over a mould. When the moulded material has cooled down, additional materials such as resin and fibreglass are integrated into the structure to make it stronger. This will ultimately mean that acrylic hot tubs tend to be more expensive compared to the other options, as there are more materials used. However, because of the quality and insulation, can withstand harsh weather and provide excellent heat retention.

Vinyl hot tubs are made by stretching a vinyl liner over a mould. The liner is then stitched or welded together. Vinyl is a less durable material than acrylic, so it’s more susceptible to tearing and UV damage. However, it’s a cheaper alternative and can be easily repaired if it does get damaged.

Rotomolded plastic is a newer material that is becoming increasingly popular for hot tubs. It’s made by heating plastic and then moulding it into shape. It’s one of the cheapest materials available on the market, but it’s also the least durable. Rotomolded plastic hot tubs can be easily damaged and are not as resistant to UV rays as other materials.

Keeping Proper Insulation In Mind

Another important factor to consider when choosing a hot tub is the type of insulation. This is especially important if you live in an area with a colder climate. With proper insulation, your hot tub will need less energy to run because you don’t have to heat it as often. On the other hand, hot tubs that aren’t properly insulated will require more energy to operate and will lose heat more quickly. During the cold winter months, the running parts of your hot tub might need to work harder to keep the water at an ideal temperature. This could put a strain on your spa in the long run. 

Some hot tubs have features that promote eco-efficiency and reduce energy costs. In fact, Hydropool spas have an advanced heat redistribution system known as Thermal Shield Technology. This feature helps keep the water warmer for longer by efficiently redistributing heat produced from other components like the jets and the pump. Hydropool hot tubs run at 100 degrees for only pennies a day, thanks to advanced insulation technology. 

Another way manufacturers incorporate insulation into the hot tubs’ structure is through foam. This spa foam has superior insulation properties and also doesn’t absorb water, so it won’t get damaged by moisture like other types of insulation.

Style and Durability Are Both Important

When choosing a hot tub, it’s important to find one that strikes the right balance between style and durability. You want a spa that will last for years to come, but you also want one that you’d love to look at and that fits your home’s aesthetic. Fortunately, there are many colours and styles available on the market. You can even go for models with side panelling that can be taken off or replaced, allowing you to customize your hot tub’s exterior easily.

There are a lot of things to consider when choosing a hot tub. But if you keep these factors in mind, you’ll be sure to find one that’s perfect for you and your family. With the right materials and features, you can have a hot tub that will last for years and provide you with endless hours of enjoyment.
