Hot Tub Thermal Blankets: Everything You Need to Know

Table of Contents


The hot tub is a fantastic place to relax, unwind, and enjoy the benefits of hydrotherapy. However, maintaining an ideal water temperature and keeping energy costs low can be a challenge. This is where a hot tub thermal blanket comes in handy. In this article, we'll dive deep into the world of hot tub thermal blankets, their types, benefits, and how to choose the perfect one for your needs.

What is a Hot Tub Thermal Blanket?


A hot tub thermal blanket is a specially designed cover that floats on the surface of the water in your hot tub. It acts as an insulator, preventing heat from escaping and maintaining a consistent water temperature.


The primary purpose of a hot tub thermal blanket is to conserve energy by reducing the amount of heat lost from the water. This helps to decrease energy consumption, lower your energy bills, and extend the life of your hot tub.

Types of Hot Tub Thermal Blankets

Floating Thermal Blankets

Floating thermal blankets are lightweight and made of insulating materials like foam or bubble wrap. They float directly on the water surface, creating a barrier that reduces heat loss through evaporation.

Insulating Thermal Blankets

Insulating thermal blankets are thicker and heavier than floating blankets, providing extra insulation for your hot tub. They're often made of materials like vinyl or closed-cell foam, which provide better heat retention.

Benefits of Using a Hot Tub Thermal Blanket

Energy Savings

One of the primary advantages of using a hot tub thermal blanket is the energy savings it provides. By reducing heat loss, it allows your hot tub to maintain its temperature more efficiently, resulting in lower energy consumption and reduced energy bills. Most are reasonably effective at doing this, however there are better hot tub insulation solutions that yield significantly larger energy and cost reductions.

Extended Hot Tub Life

Using a thermal blanket can also extend the life of your hot tub. Constant temperature fluctuations can cause wear and tear on your hot tub components, such as the heater and pump. A thermal blanket helps maintain a consistent temperature, reducing the strain on these components and prolonging their lifespan.

Improved Water Quality

A thermal blanket can also help improve water quality by reducing the evaporation of chemicals, such as chlorine, from the water. This means you'll need to add fewer chemicals to maintain a healthy water balance, which can save you time and money.

Factors to Consider When Choosing a Hot Tub Thermal Blanket


When choosing a hot tub thermal blanket, it's essential to consider the material. Look for blankets made of durable, insulating materials like vinyl, closed-cell foam, or bubble wrap. These materials provide better heat retention and can withstand the chemicals and temperature fluctuations in your hot tub.


Ensure the thermal blanket you choose is the correct size for your hot tub. Measure the dimensions of your hot tub and select a blanket that is slightly larger, allowing you to trim it to fit perfectly.


The thickness of the thermal blanket plays a crucial role in its insulating properties. Thicker blankets generally provide better insulation, resulting in more significant energy savings. However, they may also be more challenging to handle and store.

How to Install and Maintain a Hot Tub Thermal Blanket


Installing a hot tub thermal blanket is straightforward. Simply unroll the blanket and place it on the water surface, ensuring it covers the entire area. If necessary, trim the blanket to fit your hot tub's shape and size.


Maintaining a hot tub thermal blanket is relatively easy. Periodically remove the blanket and clean it with mild soap and water to remove any dirt or residue. Make sure to inspect the blanket for any signs of wear or damage and replace it as needed to maintain its insulating properties.

Alternatives to Hot Tub Thermal Blankets

While hot tub thermal blankets are an excellent option for conserving energy, some alternatives offer significant advantages in most situations. These include insulated hot tub covers, which provide more substantial insulation and protection from the elements, and solar covers, which harness the sun's energy to help heat your hot tub.


A hot tub thermal blanket is a valuable investment for any hot tub owner as they offer numerous benefits, such as energy savings, extended hot tub life, and improved water quality. When selecting a hot tub insulation solution like a thermal blanket, you need to consider all the factors we discussed, including if what you need is actually a full set of hot tub insulation. With proper installation and maintenance, a hot tub thermal blanket can significantly enhance your hot tub experience.


  • Can I use a hot tub thermal blanket with an existing hot tub cover?
    Yes, you can use a thermal blanket in conjunction with your existing hot tub cover for added insulation and energy savings.
  • How often should I replace my hot tub thermal blanket?
    The lifespan of a thermal blanket varies depending on the material, usage, and maintenance. Regularly inspect your blanket for signs of wear or damage, and replace it when necessary to maintain its insulating properties.
  • Can I use a hot tub thermal blanket in an inflatable hot tub?
    Yes, you can use a hot tub thermal blanket in an inflatable hot tub, as long as it fits properly and is made of a material compatible with the inflatable tub.
  • Is it safe to use a hot tub thermal blanket with a saltwater hot tub?
    It is probably safe to use a hot tub thermal blanket with a saltwater hot tub as long as you ensure that the blanket is made of a material that can withstand the saltwater environment. Contact the manufacturer for verification.
  • Can I cut my hot tub thermal blanket to fit my hot tub's unique shape?
    Sotimes yes, you can trim your hot tub thermal blanket to fit your hot tub's shape and size. Contact the manufacture first for confirmation and then make sure to measure your hot tub accurately and select a blanket slightly larger than the dimensions to allow for trimming. Or alternatively, you can use our bespoke handcrafted and fitted hot tub insulation solutions that fit your hot tub perfectly.
