Create a spacious traditional sauna space at home with this four-person Canadian hemlock indoor sauna. The 1800 × 1500mm cabin uses opposing two-tier benches and a full-height glazed double-door front to provide an open, symmetrical layout.

The sauna is supplied with a Harvia BC60E 6kW electric sauna heater, sauna stones, an external control panel and top-mounted single-colour LED ambient lighting.

What This Product Is

FAQ

What is a steam sauna and how does it work?
What is a steam sauna and how does it work?

A steam sauna uses an electric heater filled with sauna stones. Pouring water over the hot stones creates steam and increases humidity, giving you the traditional Finnish-style sauna experience with hot, humid air and a stronger, more intense heat.

How hot does a steam sauna get?

Steam saunas usually run at higher air temperatures than infrared models. The final temperature depends on the heater output, cabin size, and insulation. Some people prefer short, intense sessions, while others enjoy a slightly milder heat with added steam.

Do steam saunas need plumbing?

No. Steam is produced by pouring water onto the heated stones by hand. There is no built-in water supply or drain inside the sauna. The room around it simply needs normal ventilation so any moisture can clear when the door is opened.

What power supply does a steam sauna need?

Steam sauna heaters vary by model, with many home units ranging from 3 kW to 9 kW.
Important: Any heater above 2.5 kW must be hard-wired on a dedicated circuit by a qualified electrician. Always check the heater rating before installation.

How long does a steam sauna take to heat up?

Most steam saunas take around 30 to 45 minutes to reach temperature, depending on the heater size, cabin volume, insulation, and room conditions. Allowing enough preheat time helps the stones get hot enough to produce steady steam.

Do steam saunas create a lot of moisture?

Inside the cabin, yes, and that is part of the experience. Outside the sauna, moisture is usually limited and mainly escapes when the door is opened. Standard room ventilation, such as a window or extractor fan, is normally enough to manage it.

Where can a steam sauna be installed?

Steam saunas can be fitted in indoor areas such as home gyms, utility rooms, larger bathrooms, or dedicated wellness spaces. Outdoor-rated models can also be installed in gardens, on patios, or in sheltered outdoor areas. Always check whether the model is intended for indoor or outdoor use.

Are steam saunas safe to use?

Steam saunas are commonly used at home and in commercial settings. It is important to stay hydrated, avoid alcohol before use, and leave the sauna if you start to feel unwell. Anyone who is pregnant or has a medical condition, particularly heart-related issues, should speak to a healthcare professional first.

How often should I use a steam sauna?

Many people use a steam sauna three to five times each week. Beginners often start with shorter sessions of around 8 to 12 minutes, then gradually increase the time as they become more comfortable with the heat.

Do steam saunas need much maintenance?

Maintenance is generally simple. Wipe the benches after use, leave the door open so the cabin can dry, and occasionally check, clean, or reposition the stones in line with the manufacturer’s guidance.

What is the difference between a steam sauna and an infrared sauna?

A steam sauna heats the air and adds humidity to create a traditional high-heat environment. An infrared sauna warms the body more directly while keeping the air temperature lower. The right choice depends on whether you prefer a hotter, classic sauna feel or a gentler style of heat.
