Finnish Sauna – Warmth, Relaxation and Well-Being


A Finnish sauna is not just a trendy element of a wellness zone — it is above all a traditional, time-honoured ritual of relaxation and well-being, known and loved around the world. Regular use of a dry sauna, characterised by high temperature and low humidity, brings a wide range of benefits to the body. The intensive sauna heat creates a soothing feeling of warmth and supports deep physical relaxation, while a thorough sweat leaves you feeling fresh and light. Regular sauna sessions promote relaxation, well-being and greater body awareness — a particularly welcome ritual in the colder months.

Simple and Authentic

The JFO120 is a deliberately simple Finnish sauna: everything unnecessary has been left out to make room for an authentic, original sauna experience. There is no separate control panel – all functions are controlled directly via the buttons on the heater.

The colour of the RGB LED light can be changed to suit your mood, and the included accessories – bucket with ladle, thermohygrometer and hourglass – complete the classic sauna ritual. A straightforward choice for anyone who values traditional sauna heat and easy handling.

Traditional Finnish Heater with Volcanic Stones

The Finnish stove is the heart of any authentic Finnish sauna – a source of heat, atmosphere, and a ritual that has brought people relaxation and well-being for centuries. It heats the volcanic stones and the air within the cabin, creating a signature environment that is dry, deeply warming, and perfectly suited for relaxation.

The JFO120 sauna is electrically heated, which guarantees precise temperature control without the need to manage a traditional firebox. You can regulate the humidity level yourself simply by pouring water over the hot stones. The more steam produced, the more intensely the heat penetrates the body, increasing the perceived temperature inside the cabin. You decide whether your session will be dry and intense, or mild and steamy.

Another advantage: the 3 kW heater runs on standard 230 V single-phase power, so the JFO120 does not need a three-phase connection – a practical solution for smaller spaces, too.

Colour Ambience – Light for Relaxation 

The RGB LED lighting is more than a design detail. Inspired by the idea of chromotherapy, it lets you set the colour mood of your relaxation session, so your spa moment feels even more personal.

RED: A warm, vibrant shade that creates an energising, lively atmosphere.

YELLOW: A bright, sunny colour that brings a cheerful, uplifting and cosy feel.

BLUE: A cool, calm colour that creates a peaceful setting for unwinding at the end of the day.

GREEN: A fresh, natural shade that brings balance and a calm feeling to the room.

PURPLE: A soft, mysterious colour for moments of quiet reflection and mindful relaxation.

TURQUOISE: A light, refreshing shade that combines calm and clarity, ideal for deep relaxation.

The coloured lighting is an atmospheric feature designed to enhance your comfort. It is not a medical treatment.

Premium Quality Materials

The JJSPA JFO120 sauna is built from carefully selected materials that ensure durability and a timeless look. Comfortable benches let you sit at ease throughout your session – so nothing distracts you from relaxing.

The cabin is made of Finnish pine (Pinus sylvestris) with a wall thickness of 48 mm – a classic Scandinavian sauna wood. Pine is light in colour, dimensionally stable and has a characteristic, lively grain. Because wood conducts heat poorly, the benches stay pleasant to the touch even at high cabin temperatures.

During a session, the warm pine releases its typical, subtle woody scent, which adds to the authentic sauna atmosphere. Together with the 6 mm tempered glass door and stainless steel fittings, the JFO120 combines Scandinavian simplicity with natural materials.

FAQs

What Is the Difference Between an Infrared Sauna and a Finnish Sauna?

An infrared sauna uses infrared heaters that directly warm the body rather than the air. As a result, it operates at a lower temperature (approx. 40–60°C), is gentler on the body, and allows for longer, more comfortable relaxation sessions.

A Finnish sauna, on the other hand, heats the air inside the cabin to high temperatures (approx. 80–100°C), causing intense sweating and a more traditional sauna experience.

In short: an infrared sauna works more gently and penetrates deeper into the tissues, while a Finnish sauna delivers an intense, high-temperature thermal experience — making each type of sauna suited to different wellness goals and personal preferences.

How Often Can You Use a Sauna?

A sauna can be used regularly, even several times a week, and in many cases daily — depending on individual fitness and overall well-being. For infrared sauna use, sessions of 20–40 minutes are recommended 3–5 times per week, while a Finnish sauna is typically used 1–3 times per week in shorter cycles with cooling-down breaks in between.

The most important thing is to adjust the frequency to your personal needs, stay properly hydrated, and avoid overstraining your body. If in doubt, it is always advisable to consult a doctor before starting a regular sauna routine.

How Much Electricity Does a Home Sauna Use?

Based on the average German electricity price of approximately €0.30/kWh:

  • a 30-minute infrared sauna session costs approx. €0.30
  • a 30-minute Finnish sauna session costs approx. €1.50

Note: Calculations are based on the current average household electricity price in Germany (~€0.30/kWh). Actual costs may vary depending on your energy provider and tariff.

What Electrical Installation Does an Infrared Sauna Require?

An infrared sauna typically requires a standard 230 V power supply — simply a regular electrical socket. The power consumption of the device is usually around 1.5–3 kW, which means the sauna can be connected to a standard circuit (most commonly protected by a 16 A fuse). It does not require a three-phase installation or any special electrical modifications, making it extremely easy to install at home.

This is one of the key advantages of a home infrared sauna — plug-and-play setup with no professional rewiring needed, ideal for anyone looking for a hassle-free home wellness solution.

What Electrical Installation Does a Finnish Sauna Require?

Most Finnish saunas with an electric heater require a 400 V three-phase power supply. The heater output typically ranges from 3–9 kW, which means a dedicated circuit and appropriate safety protection are essential. The installation of a Finnish sauna must always be carried out by a qualified and licensed electrician.

The JFO120 is an exception: its 3 kW heater runs on 230 V single-phase power and can be connected via a 230 V / 50 Hz socket or a 3 × 2.5 mm² cable with a 16 A fuse. Please still have the connection checked by a qualified electrician.
