Insulation is often overlooked when purchasing a hot tub, but it is a crucial factor to consider. A well-insulated hot tub will save you money on energy, warm your water quicker and for longer, and help the overall longevity of the spa. Now that the colder months are approaching it's important to invest in a hot tub with the best insulation.
In this blog, we’ll explore the different types of insulation available, the importance of hot tub covers, and the overall benefits of keeping your hot tub well-insulated.
Types of Hot Tub Insulation
Several insulation types are available in hot tubs, and the one you choose can significantly impact your hot tub’s efficiency. Let’s take a look at the main options:
- No Insulation
Some budget or inflatable hot tubs come with little to no insulation. While these may seem like a cost-saving option upfront, they unfortunately often result in high energy consumption over time. Without insulation, your hot tub’s heater has to work overtime to maintain water temperature, leading to much higher electric bills. If you live in a cooler climate, this lack of insulation will be even more noticeable, with heat loss becoming a recurring issue.
- Foam Insulation
Foam insulation is the most common and effective insulation used in hot tubs. It is typically sprayed around the hot tub’s shell and internal components, helping to trap heat and keep the water warmer for longer. This type of insulation is ideal for those who plan to use their hot tub year-round, as it helps to keep energy costs lower and ensures a consistent water temperature. Foam insulation also acts as structural support for the pipes.
There are different foam insulation types, from full foam to partial foam, each offering varying levels of heat retention and energy efficiency. The better the quality of the foam (typically thicker), the better the insulation.
- Thermal Wrap
Thermal wrap insulation is a type of insulating material designed to improve energy efficiency by minimising heat loss. It's a reflective layer that traps heat inside the hot tub whilst blocking any cooler outside air from entering. This material wraps around the hot tub's shell. Hydropool thermal shields use NASA-inspired technology, designed to reflect the heat off the pumps, shell and plumbing back into the hot tub. It’s very effective for maximising heat retention.

The Importance of Hot Tub Covers
One of the simplest yet most effective ways to keep your hot tub insulated is by using a quality hot tub cover. A good-quality hot tub cover is made from durable materials, has a high-density thickness and can be fastened securely. This is particularly useful for those who use their hot tub regularly, as it cuts down on the time required for the water to heat up the next time it’s in use. Keeping the cover on when the hot tub isn’t in use can significantly reduce evaporation, saving both water and the chemicals needed to balance it.
Benefits of Keeping Your Hot Tub Insulated
When your hot tub is properly insulated, the benefits are immediately noticeable. Not only will your hot tub function more efficiently but it will also help you to save money. Plus, it's more environmentally friendly! Here’s how insulation benefits you in the long run:
- Reduced Energy Consumption
A well-insulated hot tub requires less energy to maintain its temperature. Without proper insulation, heat escapes quickly, forcing the heating system to work harder to maintain the desired temperature. Over time, this can add up, leading to significantly higher electric bills. In contrast, with proper insulation, the heating system operates more efficiently, conserving energy and reducing the environmental impact.
- Warmer Water for Longer
Insulated hot tubs retain heat more effectively, which means the water stays warmer for longer periods without needing constant reheating. This is especially beneficial for people in colder climates where heat escapes quickly. A properly insulated hot tub will hold its temperature longer, allowing you to relax and enjoy the hot water without the worry of it cooling too fast.
- Lower Energy Bills
The combination of reduced energy consumption and better heat retention means lower running costs/energy bills. This makes insulated hot tubs a cost-effective investment in the long run, as the money saved on energy can outweigh the initial investment in a higher-quality insulated hot tub.
Optional: Adding a Hot Tub Enclosure
While a well-insulated hot tub can perform efficiently on its own, some owners may consider adding a hot tub enclosure for additional protection and insulation. A cabin helps shield the hot tub from wind, rain, and snow, providing an extra layer of insulation. It also offers privacy and protection, making your hot tub experience more enjoyable, especially in colder months.
Hydropool has partnered with our sister company Cabin Master on several projects and the customers couldn't be happier.
Conclusion
When purchasing a hot tub, insulation should be one of your top priorities. It will be an investment, but in the long run, the better option. A properly insulated hot tub not only saves you money on energy bills but also ensures that your water stays warmer for longer periods, providing you with a more enjoyable spa experience. You can keep your hot tub running efficiently year-round. By focusing on insulation, you’ll enjoy a cost-effective and energy-efficient hot tub experience for years to come.
