Your Personal Home Paradise! Tips On How To Build A Sauna

There is no better place to relieve stress and unwind than a sauna. It has, for a long time, been something that only the wealthy and the very popular could afford. However, just like with hot tubs, this is barely the case these days.

In the UK, people are increasingly looking to the Scandinavian countries for inspiration, especially Finland, which has over two million saunas. As a result, and thanks to very relaxed regulations, installing your own sauna at home style=”font-weight: 400;”> has never been easier. Read on to find out how you can easily build your own and enjoy a calming atmosphere. 

What is a home sauna?

Saunas are heated to temperatures ranging from 65 to 90 degrees Celsius. The technology is straightforward. It is a small steam room, you could have inside the house or even a garden room. It has a heat source (traditional rocks or infrared) to create a humid, steamy atmosphere for relaxation, unwinding, and muscle pain relief.

It works by generating dry heat in a small enclosed space using a heater. More people are starting to realise the positive impact saunas have on health, and that’s why it seems so appealing.

Things to consider before you start

There are a few things you should be aware of before you begin building your sauna:

1. Sauna construction and design

The configuration of sauna design, relaxation area, and shower area can be customised in several ways. From the power supply to ventilation to flooring, structural conditions must be considered.

2. Which room is a good fit?

Rooms that are long and narrow, small and square, basement rooms, or attics with slanted ceilings can work perfectly.

3. The layout

You will need a custom sauna with a minimum floor area of 2x2m to fit four people. Naturally, the more room you have at your disposal, the better. Mind that the upper benches can be placed in a number of ways when deciding on a configuration. A corner connection, on the other hand, is the best choice. 

4. Ventilation

A draught-free ventilation system is crucial to ensure that stale air can be replaced with fresh air as needed. Air throughput should ideally be adjusted based on the size and the number of people who use it. This not only helps to preserve the perfect environment, but it also saves energy and money.

5. The door of the sauna

The doors are expected to open outwards for safety reasons. Transparency is provided by glass doors or fiberglass, which should be made of shatterproof materials for safety purposes. On the inside, a wooden door handle is excellent for protecting you against wood burning.

6. Decide on what type of sauna you want to install

Home saunas are divided into three categories: 

  • Finnish traditional sauna

Water is poured onto heated rocks to regulate the humidity in this wood-lined sauna. This conventional type has the benefit of being able to release damp heat at regular intervals.

  • Dry Sauna

It is similar to the traditional Finnish sauna, except that the heated rocks are not sprinkled with water.

  • Infrared Sauna

Infrared saunas, like dry ones, do not need water. The humidity level is zero. This type of has become the most common DIY project because it is simple to set up, fast to heat up (it does not need to be left on or to warm up), and requires only a wall outlet to get going. It will not make a good outdoor sauna, such as a barrel sauna, because It does not get hot enough outside. However, it is still a perfect choice for indoor use

Step-by-step guide: How to build a sauna

With careful planning and preparation, you can create a fantastic sauna. Once you have decided on which room is the appropriate one, follow these detailed steps which should serve as a guide and give you a better insight:

Step 1

Build the framework out of wood and follow traditional framing codes. Make sure there are studs in each corner. Within the sauna, the normal ceiling height should be 2.1m but this depends on your needs. Create the necessary ventilation based on the location of your door, the type of heater, and the configuration of your benches.

Step 2

Insulate the sauna ceiling and frame. Polyester insulation is favoured here, but this choice is up to you based on your budget and the climate in your area.

Step 3

Wrap the interior in aluminium foil with the silver side facing into the sauna. It is recommended that all of the joints be taped with aluminium too.

Step 4

Batten the sauna walls and ceiling to provide an air barrier between the foil and the sauna cladding. The battens also provide additional protection of the benches and the sauna heaters that are placed on the wall.

Step 5

Softwood timber can be used to clad the interior. For a neat, clean finish, use beads to finish all internal corners. As required, cut vents and pull lighting, heater supply, and thermostat sensor cables through.

Step 6

Make the lower benches and secure them in place. Open benches are often preferable to closed benches that restrict airflow.

Step 7

Time to hang your door. Keep in mind that sauna doors must open outwards, and a window in the door is highly recommended.

Step 8

Place your sauna heater and lighting in place. Place the rocks in the sauna heater and that’s it!

How much will it cost to build your own sauna?

  1. Sauna building from scratch is certainly the most cost-effective option, which was outlined above. The cost can be as follows:
  2. The price of wood and insulation will vary depending on the size of your DIY sauna. You can purchase high-quality, kiln-dried tongue and groove boards. A good sauna door will cost around £200, while heaters will cost anything from £100 to £500 or more. 
  3. Saunas that are modular can be put together in a matter of hours. Pre-assembled and fitted panels make up the home sauna kits. They certainly don’t need any special skills to assemble. A four-person sauna in modular form would cost anywhere from £2,500 to £3,500 on average.
  4. The energy cost of running an indoor sauna varies depending on the size and form. Once warmed up, saunas use half the power, so an hour of sauna in your own home will set you back around £1. Infrared Saunas are also more cost-effective because they don’t need any warm-up time and the heating elements use less energy.

What are the health benefits of sauna?

Still not convinced about making your own? Then it’s time to think again! Take a look at the numerous benefits that saunas can offer you.

1. Skin cleanser

Since steam opens pores and allows sweat to eliminate dead skin cells and bacteria, it has long been used as a natural way to benefit your skin. This is a normal process that happens in your body, but the sauna‘s heat accelerates it and gives your body a thorough cleanse.
If there is dirt deep inside your pores, the sebum makes your skin oily and blemish-prone. With all that heat from the sauna, you can rest assured that your skin will be free of those.

2. Boosts your immune system

Saunas have also been shown to be effective in preventing disease. Your immune system becomes more active as your body’s core temperature rises, allowing it to combat any symptoms of infection before an illness develops.
Sauna users will benefit from this in the long run because it allows the body to search out and eliminate possible threats on a more frequent basis. Plus, the connection between stress and the immune system has been well-documented, with the naturally stress-relieving benefits of a sauna aiding this process.

3. Relieves stress

The Romans realised early on that the sauna‘s social environment, combined with the advantages of steam, made it the ideal place to alleviate tension and relax. One of the still most common reasons today for visiting a sauna is to relieve stress, with the modern lifestyle problems providing even more incentive to do so.

4. Excellent for hair

A sauna‘s heat and steam do wonders for your hair, bringing out its lustrous qualities. Many people suggest following this procedure with a cold wash to prolong the benefits by covering the pores on the scalp. The oils released in your scalp (known as sebum) keep your hair and scalp safe and hydrated with moisture, which can help relieve dry scalp symptoms.

5. Makes you look younger

It is a perfect way to add a water cycle to your body, with sweat eliminating toxins and freshwater replenishing your natural hydration. After you get out of the sauna, drink some water to replace the fluid you lost by sweating. Wrinkles are caused by dehydrated skin, so staying well hydrated will help you avoid them.

6. Relaxes the muscles

Another excellent reason to go to the sauna is to help muscles relax after a workout. You’ll feel the burn for a shorter period of time than if you let them heal naturally. Thermotherapy is a commonly recognised method of muscle relaxation for a number of conditions, including cramps, spasms, and the discomfort associated with a rigorous workout. The benefits of gentle heat can also alleviate stiffness and discomfort in your arms and legs.

7. Improves your sleep quality

Saunas‘ stress-relieving properties may aid in the induction of deeper sleep. Aside from the natural calming effect of the steam, everything about the sauna experience is a path that will take you to a restful sleep at night. Long-term computer screen use (including phones and tablets) has been shown to affect deep sleep habits, so an evening in the sauna is a perfect excuse to put the phone down for a couple of minutes.

8. Calorie burn & weight loss

The sauna does more than just flush toxins from your system. More calories are burned as a result of the increased heart rate and sweat. So if you combine it with a good diet and some workout, you can rest assured that you’ll see faster results.

9. Boosts your stamina

Spending time in a sauna gradually exposes the body to more and more heat, increasing your tolerance for a higher internal temperature. When it comes to building up this tolerance level, using a sauna after exercise can be extremely beneficial, and it doesn’t take many visits to see the results. It takes just 5 minutes for your body to adjust to the heat, but frequent visits are recommended for a long-term impact.
