At Oceanic Saunas, we have been handcrafting saunas in England since 1982, drawing inspiration from centuries of global bathing traditions. While materials and technology have evolved, the core principles of sauna bathing, heat, ritual, craftsmanship and respect for the space, remain timeless. This article explores the rich history of saunas and steam rooms from around the world, examining their cultural importance, traditional rituals and enduring relevance in modern life.

For thousands of years, humans have used heat, steam and sweat as tools for cleansing, healing, social connection and spiritual renewal. Long before modern wellness trends, saunas and steam rooms formed an essential part of daily life across many cultures. From the smoke-filled saunas of Finland to the marble hammams of the Middle East, these heated spaces reveal much about how societies understood health, community and the human body.

The word sauna originates from Finland, where sauna bathing has been practised for over 2,000 years. Early Finnish saunas were earth pits heated by stones warmed over a fire. These evolved into log-built savusauna (smoke saunas), where smoke filled the room during heating and was later ventilated before use.

In Finnish culture, the sauna was the cleanest and most respected space in the home. Births, healing rituals and preparation of the dead all took place in the sauna, reinforcing its spiritual significance.

A defining element of the Finnish sauna is löyly, the steam created by throwing water onto hot stones. Birch branches (vihta or vasta) were used to gently stimulate the skin, improving circulation and releasing natural aromas.

Saunas were used by all members of society, regardless of age or status. Nudity was natural and non-sexual, reinforcing equality. This respect for simplicity and craftsmanship continues to influence how traditional Finnish saunas are designed and built today.

Modern Finnish saunas often use electric heaters and refined controls, yet the fundamentals: natural timber, heat, steam and ritual, remain unchanged. These same principles guide the work of contemporary sauna manufacturers who value authenticity and longevity.

In ancient Rome, public bathhouses (thermae) were central to civic life. These vast complexes featured hot rooms (caldarium), warm rooms (tepidarium) and cold plunges (frigidarium).

Roman bathhouses relied on hypocaust systems to circulate hot air beneath floors and walls. Bathing was a social ritual as much as a hygienic one, used by citizens of many social classes and often subsidised by the state.

The Roman legacy influenced later European spa culture, embedding the idea that heat bathing supports both physical wellbeing and social connection.

The Turkish hammam evolved from Roman bath traditions and became a cornerstone of Islamic culture. Hammams were designed for ritual purification, with flowing spaces, domed ceilings and warm marble surfaces.

A traditional hammam experience follows a structured sequence: warming, exfoliation with a kese mitt, soap cleansing, massage and rest. Hammams also served as important social spaces, particularly for women, and were associated with life events such as weddings.

Modern hammams may incorporate contemporary materials, yet the ritual structure has remained remarkably consistent.

The Russian banya combines high heat with high humidity. Traditionally wood-fired and built from timber, banyas emphasise endurance and contrast, often alternating intense heat with cold plunges or snow.

Birch or oak branches (venik) are used more vigorously than in Finnish saunas, reinforcing the banya’s reputation for strength and vitality.

In Japan, communal bathing centres on hot water rather than dry heat. Onsen (natural hot springs) and sento (urban bathhouses) are deeply ritualised spaces focused on cleanliness, respect and calm.

While not traditional saunas, steam rooms and heated environments often accompany these facilities, reflecting the universal link between heat and purification.

Indigenous cultures across North America have long used sweat lodges for spiritual and physical healing. These dome-shaped structures use heated stones and water to create steam.

Ceremonies are led by elders and follow strict protocols involving prayer, storytelling and reflection. The sweat lodge is a sacred space, emphasising humility, endurance and connection to the natural world.

During the 20th century, saunas and steam rooms became increasingly global. Electric heaters, improved insulation and modern steam generators made them accessible in homes, hotels, gyms and spas.

While technology improved efficiency and control, many modern sauna users now seek a return to traditional values: natural materials, craftsmanship and ritual. This balance between innovation and heritage continues to shape contemporary sauna design.

Across cultures and centuries, several shared principles emerge:

• Heat as a method of cleansing and renewal
• Ritual structure that gives meaning to the experience
• Communal use that strengthens social bonds
• Respect for the sauna or bath as a calm, mindful space

Saunas and steam rooms are not modern inventions but enduring human traditions. From Finnish forests to Middle Eastern hammams, the language of heat and steam has remained remarkably consistent.

Today, as interest in wellbeing and craftsmanship grows, these traditions continue to inspire modern sauna design and use. By respecting heritage while embracing thoughtful innovation, sauna culture remains as relevant now as it was thousands of years ago.
