Cedar vs spruce sauna
Choosing the right timber for a sauna is one of the most important decisions a buyer can make, as wood species directly affects heat retention, longevity, aroma and maintenance requirements. Gravity Wellness, a UK-registered company trading under York House Group, has spent years working with premium sauna timbers and recommends Canadian hemlock for its outstanding thermal performance and natural antimicrobial properties.
Understanding Cedar as a Sauna Timber
Western red cedar has long been regarded as one of the premium choices for sauna construction, particularly in North America and increasingly across Europe. Its natural oils give the wood a distinctive warm, spicy aroma that many sauna users find deeply relaxing and therapeutic. Cedar is a low-density softwood, which means it heats up relatively quickly and does not absorb excessive amounts of moisture during use. This combination of rapid heat-up time and moisture resistance helps cedar maintain its structural integrity over many years of regular sauna sessions, making it a durable long-term investment for serious wellness enthusiasts in the UK.
From a practical standpoint, cedar performs exceptionally well in high-humidity environments because its natural tannins and oils act as a defence against mould, mildew and bacterial growth. This antimicrobial quality is especially valuable in a sauna where temperatures regularly reach between 70 and 100 degrees Celsius and moisture levels fluctuate dramatically between sessions. Cedar also has an attractive reddish-brown tone that many homeowners find visually appealing, adding an aesthetic dimension to the wellness space. However, cedar is typically among the more expensive sauna timbers available in the UK market, and sourcing sustainably certified cedar can be a challenge depending on the supplier. Browse all Gravity Wellness saunas to see how we address timber sourcing responsibly.
Understanding Spruce as a Sauna Timber
Spruce is a pale, fine-grained softwood that has been used in Nordic sauna construction for centuries, particularly across Finland and Scandinavia where the tree grows abundantly. Its light colour and tight grain give spruce saunas a clean, minimalist aesthetic that suits contemporary interior design trends. Spruce is generally more affordable than cedar, making it a popular entry point for UK buyers who want a genuine timber sauna without the premium price tag. The wood is relatively lightweight, easy to work with during installation and widely available through European timber suppliers, which contributes to its cost-effectiveness as a sauna building material.
Despite its affordability, spruce does have certain limitations when compared directly with cedar or Canadian hemlock. Spruce contains more resin than some other sauna timbers, and at high temperatures this resin can bleed to the surface, creating sticky patches on benches and walls that require regular cleaning. Spruce is also more susceptible to moisture damage over time if the sauna is not properly ventilated between sessions, which can lead to warping or discolouration after prolonged use. For outdoor installations in the wet UK climate, these moisture-related weaknesses become particularly relevant.

Why Gravity Wellness Chooses Canadian Hemlock
At Gravity Wellness, a trading name of York House Group (Company No. 15903905), every sauna is handcrafted to order using sustainably sourced, PEFC-certified Canadian hemlock rather than cedar or spruce. Canadian hemlock occupies a compelling middle ground between the two more commonly discussed timbers. It shares cedars natural antimicrobial properties while remaining considerably more affordable, and its tight, consistent grain means it does not suffer from the resin-bleed issues associated with spruce. Hemlock has a pale, neutral tone that complements both traditional and modern interiors, and it performs exceptionally well across a wide temperature range, making it suitable for both traditional and infrared sauna applications.
Each Gravity Wellness sauna is built fresh to order from our Newark facility at Meadow House, Long Bennington Business Park, NG23 5JR, with an approximate 60-day build and delivery window. This made-to-order approach ensures that no sauna sits in a warehouse absorbing moisture or losing structural quality before it reaches the customer. All our saunas comply with UK electrical standards and operate at a maximum of 2000W, meaning they can be plugged directly into a standard UK socket with no specialist wiring required. We deliver to mainland England, Scotland and Wales.

Making the Right Timber Choice for a UK Sauna
When comparing cedar vs spruce sauna timber for a UK installation, buyers should consider several practical factors beyond initial purchase price. The UK climate is characterised by high ambient humidity, particularly in autumn and winter, which places greater stress on sauna timber than drier continental climates. Cedar performs well in these conditions due to its natural oil content, but it commands a significant price premium over spruce. Spruce is an adequate timber for well-ventilated indoor saunas, but it requires more consistent maintenance to prevent resin bleed and moisture absorption in wetter outdoor settings. Buyers should also consider the long-term cost of timber maintenance, including sanding, oiling and potential replacement of boards over time.
For buyers seeking the best sauna wood for UK conditions without overpaying for the cedar premium, Canadian hemlock represents the most balanced choice across durability, aesthetics, sustainability and value. At Gravity Wellness, we have standardised on hemlock precisely because it delivers consistent, long-term performance in British weather conditions. Whether you are considering a compact solo unit or a larger family model, our range has been designed to maximise the benefits of this exceptional timber. Visit our two-person traditional sauna or four-person traditional sauna pages to explore how Canadian hemlock performs across different cabin sizes, or browse our infrared solo sauna if you prefer lower-temperature infrared therapy.
Frequently Asked Questions
What is the fundamental difference between cedar and spruce as sauna timbers?
Cedar and spruce differ most significantly in their natural oil content, density and resistance to moisture. Cedar contains natural tannins and oils that repel moisture and inhibit bacterial growth, making it highly durable in humid sauna environments where temperatures regularly exceed 80 degrees Celsius. Spruce is paler, more affordable and widely used in Nordic sauna traditions, but it contains more resin, which can bleed to the surface at high temperatures and requires more frequent maintenance to keep benches and walls clean and splinter-free.
Which timber delivers better health and wellness benefits in a sauna?
Both cedar and spruce support the core health benefits of regular sauna use, including improved circulation, muscle relaxation and stress reduction. However, cedar has a measurable advantage in wellness environments because its naturally occurring antimicrobial compounds help suppress bacterial and mould growth on surfaces. Studies indicate that regular sauna use at temperatures between 70 and 100 degrees Celsius can reduce cardiovascular risk markers, and a cleaner, low-maintenance timber like cedar or Canadian hemlock ensures that hygiene standards are easier to maintain between sessions.
Which is easier to install in a UK home or garden?
Both cedar and spruce saunas can be installed indoors or outdoors in the UK, but the installation experience depends more on the sauna design and electrical specification than the timber itself. Gravity Wellness saunas are built to UK electrical standards at a maximum of 2000W, which means they plug directly into a standard 13-amp UK socket with no specialist wiring or additional circuit required. This makes installation straightforward for most UK homes, whether the sauna is placed in a spare room, garage or garden. Delivery is included to mainland England, Scotland and Wales.
Which sauna timber costs more to maintain day to day?
Spruce generally demands more day-to-day maintenance than cedar or Canadian hemlock because its higher resin content causes surface bleed at elevated temperatures, requiring periodic sanding and cleaning to keep the cabin hygienic. Cedar is more self-maintaining due to its natural oils, though occasional light sanding of bench surfaces is still advisable once or twice a year. Canadian hemlock, used exclusively by Gravity Wellness, combines low maintenance requirements with excellent thermal performance, keeping ongoing upkeep costs to a minimum over the lifetime of the sauna.
Which sauna timber does Gravity Wellness recommend for first-time buyers?
Gravity Wellness recommends Canadian hemlock for all first-time sauna buyers in the UK. Hemlock sits between cedar and spruce in terms of price, but matches or exceeds both in terms of long-term durability and maintenance simplicity. It is naturally antimicrobial, PEFC certified for sustainable sourcing and performs consistently in the damp British climate. Every Gravity Wellness sauna is handcrafted to order with an approximately 60-day build window, ensuring the timber is worked fresh and reaches the customer in optimal condition rather than deteriorating in warehouse storage.
