Why buy Sauna 2.0?
Sauna 2.0 brings together premium materials, thoughtful design, and a refined heating experience in one compact wellness product. A Finnish-style electric sauna with a prefab wooden cabin, your choice of Harvia or HUUM 9 kW heater, and a redesigned airflow system that circulates heat floor to ceiling — wrapping around you completely instead of escaping through the top.

No screws. No frustration. Just a sauna that performs exactly as it should, every single session.
Thermowood construction
Thermowood provides excellent insulation and resists heat and moisture, ensuring the electric sauna maintains its durability and efficiency for years to come.
Stainless steel frame
The stainless steel frame offers both structural strength and a modern design, making it resistant to wear while preserving its sleek appearance.
Heat-retaining glass
Our amber glass allows natural light in while minimizing heat loss. This ensures Sauna 2.0 stays cozy and efficient without compromising its open, modern feel.
Icetubs design
Designed to match the Icetubs collection, it complements your IceBath or IceBarrel while delivering the same premium materials and engineering excellence.
An electric sauna with two heater options
Sauna 2.0 is available with two 9 kW electric heater options, each offering a different control experience. The Harvia Cilindro provides simple mechanical control directly from the heater. The HUUM STEEL adds a digital control experience through the UKU Glass panel, with optional WiFi access through the HUUM mobile app. Both heaters are matched to the sauna room volume and deliver traditional dry sauna heat with strong stone-based steam quality.
Harvia Cilindro 9 kW
A floor-standing stainless steel heater with a large stone capacity. Operated with a mechanical timer and thermostat knob built into the heater base. A reliable choice for users who want direct and straightforward control.
HUUM STEEL 9 kW
A floor-standing heater with a slim steel shell and generous stone volume. Operated through the UKU Glass control panel mounted outside the sauna. Optional WiFi connection allows preheating through the HUUM mobile app.
Control experience
The main difference between the two heater options is how the sauna is controlled. Harvia offers immediate mechanical control at the heater. HUUM offers a more digital experience with an external control panel and optional app control.
Electrical setup
Sauna 2.0 requires the correct power setup before installation. Heater installation and internal heater connection must be carried out by a qualified electrician.

Why people choose our sauna

Relaxation and heat exposure
Step into steady warmth, quiet air, and a space that helps you slow down, switch off, and fully exhale.
Contrast therapy ready
Move from warmth into cold and back again with a contrast experience that feels energising, grounding, and alive.
Shared wellness moments
From solo reset moments to long conversations in the heat, Sauna 2.0 creates space for connection as well as calm and recovery.
Indoor or outdoor flexibility
Suitable for indoor and outdoor installation where the correct setup conditions are met.
Refined modern design
Natural materials, warm textures, and clean lines come together to create a sauna experience that feels refined, calm, and considered.

New curved ergonomic benches shaped to support your spine and lower back. When your body stops fighting the surface, sessions get longer and relaxation goes deeper.
Warm materials, refined finish
ThermoWood exterior, glass frontage, stainless steel details — including a new door handle and Icetubs-branded door step. The things you touch every single session, done right.
Ventilation that works for you
Adjustable vents manage heat during your session and dry the cabin properly after — protecting the wood and keeping the experience consistent for years.
What people say
“My private wellness oasis”
Have an IceBarrel for a year now. I love it but was missing the sauna. That is why I was so happy Icetubs came with Sauna 2.0. Now? My own private wellness in my garden :)
"So happy with my Sauna 2.0"
Honestly best buy I have made in 2025! I already had the IceBath XL and now Sauna 2.0 completes me. No more expensive memberships for me, just my Icetubs <3
"Worth it"
Wanted a sauna for years. Everything was too big or ugly. Then I found this. Perfect size and best part I can play around with the window panel which honestly is the coolest part of Sauna 2.0. Best money I’ve spent.

What is the difference between the Harvia and HUUM heater options?
Both are 9 kW heaters sized for the sauna room. The main difference is control style and the quantity of stones in each heater. Harvia uses mechanical controls built into the heater and heating stone’s weight of 80kg, while HUUM uses the UKU Glass control panel and can optionally connect to WiFi and the HUUM mobile app, with an approximate weight of heating stones of 150kg.
Does Sauna 2.0 need ventilation?
Yes. Good airflow is essential for even heat, safe wood temperatures, and drying after use. The Sauna 2.0 uses a three-vent system: a fresh air intake, an exhaust vent, and a drying vent that stays open between sessions to let the sauna dry, then closes during use for optimal airflow and a richer sauna experience.
Who should install the heater in Sauna 2.0?
The heater installation and internal connection must be carried out by a qualified electrician. The power supply must be installed by an electrician.

What is the difference between the old IceSauna and the Sauna 2.0?
Sauna 2.0 is a significant step forward from the original. The key upgrades are a redesigned airflow system that circulates heat floor to ceiling so warmth wraps around you fully rather than escaping through the top. New curved ergonomic benches shaped to support your spine and lower back for longer, more comfortable sessions. A new stainless steel door handle and Icetubs-branded door step. And the HUUM heater option now includes WiFi and mobile app control via the UKU Glass panel, so your sauna is warm before you've even stepped outside. The cabin structure, prefab self-build format, and core sauna experience remain — everything that was already great about the original, refined and improved where it matters most.
