Best Sauna Heater Buying Guide

Before making the final decision, there are some aspects you should be aware of. You need to formulate which sauna is better for you. Now let’s begin, shall we?

  • Size

The most suitable sauna heater for you has to fit in your home. Otherwise, there is no point in considering it. You do not want to ruin the design of your spa room.

Secondly, the size of the room that it can heat up must not be overlooked. This is mentioned in the specifications of most of the products. Therefore, you must ensure you know the size.

If the sauna room size exceeds the mentioned number, then the appliance is not for you. Therefore, one has to be extra careful.

  • Heat-up Time

Bear in mind that the faster your unit heats up, the less long the heat will last. For sauna heaters that take more time to fire up, the materials they are made of have more temperature inertia.

A thermometer can be used to measure the performance of the heating appliance. This is in case if you can’t decide if it heats slow or fast. These measures are essential in order to know the nature of the product.

While it is true that most customers want heaters that work faster, the factor of the durability of heat can be hard to ignore. Sauna thermometers should also be used due to safety reasons.

  • Controller

Another factor that you should also think about is the controller. You ask us why? This is because of the reason that the controller heavily affects the performance of the device.

Most cheap heaters come with controllers at the bottom of the unit. Hence, before entering the sauna, you must turn it on. Then, it might take thirty to forty-five minutes.

The controllers might even become hot. External controllers are better since the temperature can be monitored whether you are inside or outside of the room.

  • Material

You should always check on the material of the sauna heater. This is done because high-quality materials mean more life of the product.

Examples of good materials include stainless steel and Teflon. Since the sauna operates at extreme temperatures, the quality of the materials is highly integral. You don’t want your sauna heater to break over a short duration.

Also, it can be dangerous if the material is not of acceptable quality. A fire may take place, and you surely want to avoid that!

  • Set-up

Before purchasing the best sauna heater, you have to consider the difficulty of setting it up. If you don’t want any assistance, look for one that is easy to install.

If you are planning to use professional assistance, then it won’t be a tough decision. This will also save time!


Here comes the part which everyone was waiting for. You must be excited to know which sauna heater is our top pick!

While the Vevor Wall Mount 9KW Dry Steam Bath Sauna Heater might have the best value, the winner is Tylo Sense Sport 8 Heater! It is strong and durable.

The risk of the user getting any burns is reduced to a noticeable extent. You’ll be impressed by how quickly it fires up. Plus, do not forget the option to use aromatherapy to soothe your senses further.
