Patented Air Blending System: Saunum’s Air Blending System is a patented, award-winning design that actively mixes hot and cool air inside the sauna, creating a more balanced and breathable environment. This reduces heat stratification, easing head pressure, lowering discomfort, and allowing you to enjoy longer, more comfortable sessions. The result is a smoother, more even heat experience that budget sauna heaters can’t match.

.

5 Integrated Sauna Modes: Tailor every session to your mood, body, and wellness goals. Choose the intense, purifying heat of a traditional dry sauna to stimulate circulation and detoxification, or switch to the soft setting, for a gentle experience. You may opt for the steam-enhanced modem which boosts relaxation while keeping breathing comfortable. Or, you may choose the aroma mode with infused essential oils, transforming your sauna into a sensory ritual that calms the mind and relieves stress. The choice is yours.

Your Free Gift: Choose from the available aroma sets, designed to invigorate the senses.

.

Your Free 60kg Polished Heater Stones: Worth £129, but free with your heater when you choose to shop with us.

.

Your Saunum Heater: Your stunning heater will arrive already wired for UK electrical systems, making it easy for your electrician to install. It comes with an award-winning, integrated patented air blending system, which evenly circulates and mixes hot and cool air to create a more balanced, comfortable sauna temperature from floor to ceiling.

Saunum Award Winning Spa Session Sauna Heater

24 MONTH GUARANTEE, FREE DELIVERY & FREE GIFT*
£4,199.95 
Save 0% today

The Saunum Spa Session Heater is designed with patented sauna climate technology, which actively blends air layers inside the sauna to reduce temperature differences and create steam that feels softer, more even and easier to enjoy for longer sessions. A large stone mass and engineered stone basket support steady heat and consistent steam, while the climate system works continuously in the background to balance the sauna atmosphere rather than relying on heat alone. This approach was recognised with the Golden Wave 2024 innovation award, a highly competitive European industry award judged by sauna and wellness professionals. The heater is available in a  6 kW and 9 kW configuration and integrates control directly into the unit via a built-in digital touchscreen, with optional app control for added convenience. Supplied as a complete set, it includes the heater, integrated climate device and controller, offering a refined sauna experience backed by recognised industry innovation. The Spa Session Heater is complete with 5 sauna climate modes.

Your 5 Integrated Sauna Modes

Classic Nordic Sauna 

(60–100 °C)

Hot and dry! This is the traditional Nordic sauna experience, with higher temperatures and drier air. It feels intensely warm and invigorating, helping to relax muscles, improve circulation, and create the authentic effect cherished for centuries. 

Humid, Steam Rich Sauna

(60–100 °C)

Soft, soothing, and steamy! This mode uses more humidity and lower temperatures, so it feels gentler and easier to breathe in. The moist heat is very relaxing, helps prevent the air from feeling too dry, and is ideal if you prefer a steam-room-like experience. 

Mild, Relaxing Sauna

(40–55 °C)

Gentle warmth. This mode uses more humidity and lower temperatures, so it feels gentler and easier to breathe in. The moist heat is very relaxing, helps prevent the air from feeling too dry, and is ideal if you prefer a steam-room-like experience. 

Salt-Ion Sauna

(40–100 °C)

Wellness focussed air quality. Adding salt spheres releases salt ions into the air. It feels similar to a regular sauna but with cleaner, fresher air. Many people find it helps create a more refreshing atmosphere and supports easier breathing and overall wellbeing. 

Aromatherapy Sauna

(40–55 °C)

Gentle warmth. This mode uses more humidity and lower temperatures, so it feels gentler and easier to breathe in. The moist heat is very relaxing, helps prevent the air from feeling too dry, and is ideal if you prefer a steam-room-like experience. 

 

FAQS

01. Where can I find an installation guide?

Installation Guide

02. What's the difference between an open and closed basket?

The open basket exposes the stones for a stronger löyly which creates a more traditional sauna feel, while the closed basket encloses the stones to create a smoother, more controlled steam and a cleaner, premium look — with the added benefit of extra physical shielding around the stones. Some people prefer the closed basket if they have a family, however, both meet the same EU safety standards.

03. Why should I invest in a sauna heater from Estonia?

Choosing a Saunum heater designed and manufactured in Estonia means buying a product created by leading experts whose daily lives are shaped by sauna culture. These heaters are thoughtfully developed, tested, and refined in real sauna conditions. Why choose an inferior product, when you can choose a premium sauna heater from the very birthplace of sauna culture?

04. What's so special about the Saunum patented air blending system?

The Air Blending System is an exclusive, patented engineering solution, not a minor variation or "add-on" to an existing heater design. No other sauna heater can replicate this technology. The patent covers how airflow, stone mass, and heater structure work together. For you, this delivers real benefits — easier to breathe due to better air mixing, less head pressure so you don't have to wear a sauna hat, less sweat, reduced dizziness, and a more enjoyable, comfortable experience. With regular sauna heaters, it can become a challenge holding a conversation as the heat intensifies. With a Saunum, that challenge is eliminated. Choosing a Saunum sauna heater is a status marker. You'll own a piece of leading industry innovation in the heart of your sauna.

05. I'm a sauna beginner, is this suitable for me? 

Absolutely! For you, this is a match made in heaven. Unlike many other sauna heaters on the market, the Saunum heater's advanced climate regulation technology lets beginners start with gentle, comfortable modes like Mild (40–55 °C) or Humid Steam (45–60 °C), which feel softer, easier to breathe in, and far less intense than traditional saunas. As you gain confidence, you can gradually explore hotter Classic Nordic settings or enjoy Salt Ion and Aromatherapy modes, giving you a spa-like experience that grows with you.

06. How do I know which Saunum heater is right for me? 

We're here to listen and help you get it right with balanced advice, so you can freely make an informed decision. You are always welcome to give us a call, or an email, to talk it through. You can also explore the specs on each product page, where we've clearly outlined the recommended sauna volume, ceiling height, and kW rating. You also get to choose from optional extra features. Ultimately, we're here to support you on your sauna journey, so you're totally comfortable and in control of your decision.

07. Why are sauna cabins and sauna heaters sold separately?

Saunas and heaters are sold separately because no two sauna spaces or users are quite the same. Keeping them separate lets you choose the right heater size, output, and features for your specific room and how you like to sauna, rather than settling for a generic, bundled option. It also gives you flexibility in the future, whether you want to upgrade the heater or refine the experience without changing the whole sauna.

08. Who can install the sauna heater for me?

A Saunum heater must be installed by a qualified electrician. Sauna heaters are hard-wired, high-load electrical appliances, so professional installation is essential to ensure safety, correct operation, and compliance with electrical regulations — and it’s also required for the warranty to remain valid.

09. When should I expect delivery?

There is a short wait of 2 weeks for your heater to arrive via kerbside delivery from a trusted courier. They will handle your heater with care.

10. What happens if I change my mind?

We believe you'll fall in love with your Saunum heater. However, if you do change your mind, we do accept returns. You can write to us to request a return at hello@icecoldspice.com. Please also click to read our full returns policy.

Why We Love Saunum Heaters

Our appreciation for Saunum saunas started in Tallinn, Estonia, when we went to visit the people behind the product. Here, sauna has been a way of life for centuries. It’s where people reset after a long day, strengthen their bodies, and find stillness in a fast-moving world. Sauna is part of the national identity. 

 

This means Saunum represents the perfect balance of heritage and innovation. These heaters honour a long, deep roosted history of Estonian sauna culture while solving the comfort limitations of conventional heaters. The result is a sauna experience that's deeper. Every detail reflects Estonia’s uncompromising relationship with sauna, with respect for craftsmanship, authenticity, and wellbeing over gimmicks or excess. 

 

The result is a sauna experience you'll fall in love with.
