"I was looking for a specific radiator that I found on the Ice Cold Spice web site at a price that was a bit better than any other supplier. What clinched it for me was that they were supplying fancy radiator valves at literally half the price of another major supplier."

FAQS

Where can I find an assembly guide and technical specs?

Installation Guide

Which heater do I choose?

All three 6kW heaters provide outstanding performance for home saunas. The best choice depends on whether you prioritise value, design, or smart technology.

Harvia The Wall E 6kW
A sleek, compact heater that offers excellent value and dependable Finnish engineering. It heats up quickly, is easy to use, and delivers consistent, comfortable heat for everyday sauna sessions.

Huum Drop 6kW
An award-winning designer heater with a distinctive teardrop shape. Its large stone capacity creates soft, long-lasting steam, making it the perfect choice if you want a beautiful centrepiece and a traditional sauna experience. Wi-Fi control is available as an optional upgrade.

Harvia Spirit 6kW
A premium wall-mounted heater featuring elegant Scandinavian design and built-in Wi-Fi control. It offers fast heat-up times, even heat distribution, and the convenience of controlling your sauna remotely from your smartphone.

How many people does the sauna fit?

The sauna seats 2 people.

Which interior cladding & bench material do I pick?

All of our timber options are excellent for saunas. The right choice depends on the look, feel, durability, and budget you're after.

Scandinavian Spruce
The classic sauna timber. Light in colour with a natural knot pattern, it's durable, affordable, and creates a traditional Nordic sauna feel.

Thermo Pine
Heat-treated for enhanced stability and moisture resistance. It has a rich golden-brown colour and is an excellent choice for those wanting a warmer, more premium appearance.

Black Alder
A luxurious hardwood with a smooth finish and very few knots. It stays comfortable to the touch, making it ideal for benches and creating an elegant, contemporary sauna.

Aspen
A light-coloured hardwood with a clean, knot-free appearance. It remains cool to the touch and is perfect if you prefer a bright, minimalist interior.

Thermo Aspen
Our premium timber option. Heat-treated for exceptional durability and stability, it features a beautiful deep caramel tone, minimal movement over time, and a refined, high-end finish.

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.

Can you help me install the sauna?

Yes. The sauna is delivered flat-packed, so if you'd like help with installation, simply select professional assembly at checkout and we'll provide a tailored quotation for build and positioning. We're happy to review site photos or plans in advance to help determine the most suitable approach.
