Types of Outdoor Saunas

Wood-Burning Sauna

Wood-burning saunas have been around for centuries. Early versions of these saunas were used by ancient cultures in Europe and North America to bring people together for social events, as well as for healing and wellness purposes.

Wood-burning saunas are still popular today because they offer a unique experience that can’t be found in other types of saunas.

Unlike traditional electric or gas-powered saunas, wood-burning saunas burn wood (usually birch wood) to create steam and heat up the room. As the wood is slowly burned, it creates a relaxing aroma that adds to the overall pleasant atmosphere of the sauna.

The heat created by the burning wood is dryer than other types of sauna, making it more intense. Many people appreciate this more intense heat in a wood-burning sauna, giving them an invigorating feeling after a session.

The benefits that come with using a wood-burning sauna are numerous. Aside from being able to relax in an inviting atmosphere, sitting inside one can help relieve stress and headaches, improve sleep quality, reduce inflammation, and increase circulation throughout the body. Additionally, sweating out toxins through its use can also improve overall health and well-being.

For those looking for the ultimate relaxation experience with all of its added health benefits, a wood-burning sauna is definitely worth considering. With its gentle heat and subtle aroma from burning birchwood logs, it’s no wonder why these types of saunas have been around for so many years – and why they remain popular today!

Electric Saunas

Electric saunas are becoming increasingly popular as a convenient and efficient way to enjoy the many health benefits of sauna sessions. Unlike wood-burning saunas, electric models don’t need firewood and can be powered with electricity or natural gas.

Many modern electric saunas are also equipped with advanced features such as radio, sound systems, adjustable heat settings, and even air conditioning that make them even more comfortable for users.

The main benefit of using an electric sauna is its convenience. They require minimal setup and are easy to use since you just need to turn it on and set the desired temperature.

Additionally, they usually come pre-assembled and ready to use, so you won’t have to spend time constructing your own structure like with a wood-burning model.

Electric saunas also produce less steam than wood-burning models but offer higher temperatures more quickly, making them ideal for short but intense sessions.

This makes them great for those looking to sweat out toxins in a brief amount of time or who don’t have access to outdoor space where they can build a traditional wood-burning model.

However, electric saunas do have some drawbacks when compared with their wood-burning counterparts. For example, they tend to cost more up front due to the installation of electrical wiring and other components needed for operation.

Additionally, they aren’t quite as efficient in terms of energy consumption since they use electricity instead of burning firewood directly in order to create heat. And lastly, since there is no real flame present in an electric sauna session, users may not experience the same enjoyable scent that comes from burning logs like in a wood-burning sauna session.

Infrared Saunas

Infrared saunas have gained growing recognition in the past few years because of their health advantages and lower risks than other types of sauna. Rather than traditional wood-burning or electric styles, infrared saunas generate heat by utilizing infrared light which is then transferred to the body resulting in a pleasant deep sweat.

Additional advantages from using an infrared sauna are muscle pain relief, promotion of better blood circulation, enhanced immunity system functioning, weight loss assistance and minimized stress levels.

Instead of needing to be heated at a tremendous rate, like wood-burning and electric saunas do (reaching around 200 degrees Fahrenheit), infrared saunas provide a more comfortable experience as they typically remain between 100-140°F.

This is due to the fact that their light penetrates much deeper into users’ skin than traditional heat sources can, allowing them to reap all the therapeutic benefits while avoiding potential damage from intense temperatures. Infrared saunas are thus safer for those who may not tolerate high heats well.

One of the key advantages of using an infrared sauna compared to traditional models is its energy efficiency. As it uses less electricity than other types, you will be saving a lot every month in your electric bills – making it perfect for anyone looking for an economical way to reap all the benefits from regular saunas sessions.

Unfortunately, there are some drawbacks to using infrared saunas as well. For instance, since they don’t reach high temperatures like traditional models do, many users feel that their sessions aren’t long enough or intense enough with an inadequate sweat being produced.

Moreover, since they use solely infrared light instead of regular heating elements such as wood-burning and electric ones utilized by other models – if something goes wrong with your unit over time then repairs can be costly and replacement even more so.

Steps in Building Your DIY Sauna

1. Start Choosing A Location

When choosing a location to build an outdoor sauna, there are several factors that should be considered.

First and foremost, the location should be away from any structures or trees that could potentially catch fire from the heat generated by the sauna.

Additionally, you should ensure that the area is level in order to create a safe and comfortable experience for those using it.

Furthermore, it should be in a place with good air circulation – ideally near an outdoor area with plenty of fresh air as this will help to keep the sauna cool when not in use. It is also important to consider whether or not you have access to an outdoor electrical source for electric models, as well as any other features such as benches, windows, and ventilation systems.

Once these factors have been taken into account you can begin looking into other considerations such as privacy and noise levels. For instance, if you wish to avoid disturbances then it would be wise to locate your outdoor sauna away from roads or other sources of high noise levels.

Alternatively, if you would like others to enjoy your outdoor sauna then look for an area that offers easy access without being too visible.

Finally, before deciding upon a location make sure to choose one with enough space around it so you can safely enter and exit your outdoor sauna without risk of injury or discomfort. In doing so you can ensure your outdoor sauna is both safe and enjoyable for all who use it!

2. Prepare The Needed Materials

First, is the type of wood. The type of wood used for outdoor saunas is very important as it affects performance, safety and the overall look of your outdoor sauna. Different types of wood have different levels of heat insulating properties and water absorption rates which can impact how hot the outdoor sauna will get and how long it stays warm.

Certain woods are more resistant to cracking, fires, bugs and rot while others are known to be more attractive when finished with stains or paints. Selecting a high-quality wood that performs well while also meeting your budget is key in constructing an outdoor sauna that looks great and lasts a long time

Cedar is the ideal wood for outdoor saunas, as it has excellent heat insulating properties and resistance to fire, cracking, bugs and rot. Cedar has a pleasant aroma when used in outdoor saunas which adds to the overall experience, while its natural oils help prevent moisture build-up inside the outdoor sauna.

Its attractive appearance makes cedar wood ideal for outdoor saunas that are meant to be displayed in yards or other outdoor areas for an enjoyable look. Finally, cedar is very durable and can last a long time without requiring replacement – making it one of the best woods to use when building an outdoor sauna.

You can pick between concrete and wood for your floor, and it won’t really affect much how your outdoor sauna will perform because the steam from your sauna will always go up and around the room.

And now the crucial part, you need to choose between wood-burning, electric, and infrared saunas. If you want that traditional, and authentic experience of a sauna get the wood-burning type of sauna. For this guide, we’re gonna focus on building the wood-burning sauna.

3. Start Building

Building the foundation of an outdoor sauna is an essential step in the overall construction process. The foundation needs to be sturdy enough to support the weight of the sauna, as well as provide a base for other components.

It should also be built with sufficient insulation and waterproofing materials to protect against moisture, mold, and rot.

The most common type of outdoor sauna foundation is a concrete slab or block wall foundation. This type of foundation requires a flat, site-prepared surface that includes a vapor barrier and effective drainage system.

A professional contractor can help you determine the best method for your specific outdoor sauna build.

To prepare the site, it’s important to clear away all organic matter such as trees, plants, rocks, soil and sand. Digging down around 6 inches below grade allows room for gravel to be poured in as necessary for proper drainage systems.

Once this is done, lay down polyethylene sheeting over the dug area before pouring in 4-5 inches of concrete or masonry blocks—or both if needed—to form your outdoor sauna‘s base foundation.

If planning on insulating your outdoor sauna after construction, it’s recommended that 2-3 inches of foam board insulation are placed between the concrete slab/masonry block walls prior to pouring in concrete or laying bricks over it—whichever option chosen for building.

This helps reduce energy costs associated with heating up your outdoor sauna space. Begin installing your sauna benches so that you know where to put your sauna stove as well. Install the sauna door last because it’ll hinder you from putting other equipment inside the dome while working.

Once finished building your outdoor sauna‘s foundations and adding any additional desired insulation materials, you’re ready to start construction on the rest of your outdoor sauna!

As always, when attempting DIY projects like these it’s crucial to consult local laws and regulations regarding outdoor structures beforehand so that you can make sure you stay compliant during construction.

4. Setup your Heating

Since we’re aiming for a traditional sauna, we’re going to be focusing on setting up your wood-burning stove sauna heaters.

When setting up a wood burning outdoor sauna, there are several considerations to take into account. First, it is important to select the right type of wood for the stove.

Opt for hardwoods such as oak, ash, and birch which create a higher heat output and burn for longer periods of time without needing to be replenished.

Next, it’s essential to make sure the outdoor sauna is located in a dry space that is well ventilated. With outdoor units you must remember that moisture from rain and snow can quickly cause damage so avoid areas close to bodies of water or places with heavy humidity.

When installing the outdoor sauna, it’s important to make sure that all of the components are level and secured firmly in place. This includes securing the foundation posts into concrete footings that reach at least one foot below ground level; this will help protect against shifting due to weather and other external factors.

Additionally, placing insulation boards between the foundation and walls can help reduce heat loss while also increasing energy efficiency.

Once all of these steps have been completed you can begin building your outdoor wood-burning stove. Generally speaking it should be constructed near an opening in one of two walls that allow easy access for firewood and air intake/exhaust for ventilation purposes.

The stove should be made from durable materials like cast iron to ensure optimal performance over time and its design should include both an oven chamber and a heating chamber with a chimney above it allowing smoke and heat to escape easily yet efficiently.

When constructing the stove itself make sure there is enough space between components to avoid overheating and potential fire hazards while ensuring proper airflow throughout.

When your outdoor sauna is completed make sure you use firewood seasoned or kiln-dried to reduce moisture levels which helps promote efficient burning within the stove itself while also producing less smoke during combustion.

Additionally, always keep safety in mind when using all outdoor heating sources by taking necessary precautions prior to lighting any fires inside your outdoor sauna.

5. Create a small vent for your Sauna

Having a small vent for your outdoor sauna is an essential part of its installation. Without proper ventilation, the risk of smoke inhalation, fire hazards, and buildup of toxic gases increases significantly. Additionally, having a properly installed vent ensures that the sauna maintains an optimal temperature while using less energy.

When installing the outdoor sauna vent, it’s important to ensure that it is placed in a location that will allow for adequate air intake and exhaust.

It should also be situated away from locations where snow or rain can easily enter while at the same time ensuring that it is high enough to be seen but not too close to other structures or trees as this could lead to potential fire hazards.

Additionally, when building the outdoor sauna make sure there is enough space between components to avoid overheating and take into consideration any local codes and regulations regarding outdoor fires and smoke emissions.

The outdoor sauna vent should be constructed with durable materials like galvanized steel which are designed for outdoor use and can withstand extreme weather conditions without wearing down over time.

Generally speaking it should measure approximately 6-8 inches wide and 3-4 feet long so as to provide ample air flow throughout the unit while still being within standard code requirements.

Additionally, when attaching the outdoor sauna vent make sure you have included appropriate seals and weather strips which help reduce drafts while keeping out moisture from rain or snowfall.

Ultimately having a correctly installed outdoor sauna vent helps ensure your safety while maximizing efficiency within your outdoor heating source.

6. Add Finishing Touches

Adding decorations and personal touches to your outdoor sauna can help breathe life into the space, turning it into a cozy retreat that you’ll love spending time in.

Some popular decorative accessories for outdoor saunas include shelves and hanging plants, as well as soft lighting fixtures like lamps, candles, or electric lights. These pieces will help to create a warm and inviting atmosphere that can be enjoyed for hours on end.

When choosing decor for an outdoor sauna, make sure to select items made with materials that are resistant to water and heat as these will be able to withstand the elements better than other options.

For example, outdoor-rated furniture such as rattan chairs or outdoor fabrics like canvas can be used to bring comfort and style while being able to handle the changes in temperature without damage. Additionally, outdoor rugs are a great way to add texture and color to the space without sacrificing safety since they have non-slip properties which prevent slips and falls when wet.

You could also use outdoor-friendly art pieces like mosaics or metal sculptures for a more personalized touch. Adding these items can help make your outdoor sauna feel more like home by curating a collection of items that reflect your style and personality.

Hanging mirrors on the walls of your outdoor sauna is also a great way to bounce light around the room while adding an eye-catching element of design.

Ultimately, making sure you’re using materials designed specifically for outdoor use is essential when adding decorations and personal touches to your outdoor sauna so that the space is both functional and aesthetically pleasing in any weather conditions!
