Are Wood Fired Hot Tubs Safe?

Hot tubs have been a popular relaxation and therapeutic tool for many years. They provide a soothing experience and offer numerous health benefits. However, with the increasing popularity of wood-fired hot tubs, many people have concerns about their safety. In this blog post, we will explore the safety aspects of wood-fired hot tubs and address common questions and misconceptions.

1. Construction and Design

Wood-fired hot tubs are typically made from high-quality materials such as cedar or redwood. These woods are naturally resistant to rot and decay, making them suitable for outdoor use. The tubs are built with sturdy construction and designed to withstand high temperatures without compromising safety.

Additionally, wood-fired hot tubs are equipped with safety features such as a chimney or a smokestack to release the smoke and gases produced during the heating process. This ensures that the tub remains safe and comfortable to use.

2. Water Heating

One of the main concerns with wood-fired hot tubs is the heating process. It is important to note that the water in the tub is not heated directly by the fire. Instead, a separate external stove or heater is used to heat the water, while the tub itself remains cool to the touch.

Wood-fired hot tubs are designed with a water circulation system that allows for efficient heating. The heated water is circulated back into the tub, ensuring an even distribution of heat and eliminating the risk of scalding.

3. Fire Safety

When it comes to fire safety, wood-fired hot tubs are designed with precautionary measures in mind. The firebox, where the wood is burned, is separated from the tub by a protective barrier. This prevents any direct contact between the fire and the tub, reducing the risk of accidental burns or damage.

It is important to follow the manufacturer’s instructions and guidelines for the safe operation of the hot tub. This includes proper wood placement, regular cleaning and maintenance, and ensuring a safe distance between the tub and any flammable materials.

4. Maintenance and Care

Proper maintenance and care are essential for the safe operation of any hot tub, including wood-fired ones. Regular cleaning and inspection of the tub and its components can help identify any potential issues and ensure their timely resolution.

It is also recommended to use high-quality wood and avoid using treated or chemically treated wood that can release harmful fumes when burned. Regular water testing and treatment are necessary to maintain water quality and prevent any potential health risks.


Wood-fired hot tubs can provide a unique and enjoyable hot tub experience. When properly constructed, designed, and maintained, they are safe to use and offer a natural and eco-friendly alternative to traditional hot tubs.

However, it is important to always prioritize safety and follow the manufacturer’s guidelines. By doing so, you can enjoy the many benefits of a wood-fired hot tub while ensuring a safe and relaxing experience.
