Choosing the best wood for saunas is one of the most important decisions in any build, affecting comfort, aroma, durability and cost. The right timber stays cool to the touch, resists moisture and warping, and creates the inviting atmosphere that makes a sauna a joy to use. This guide compares the most popular sauna woods, cedar, hemlock and spruce, along with a few excellent alternatives, so you can select the perfect material for your home or commercial sauna.
Quick summary: Western Red Cedar is the premium all-rounder, aromatic and naturally moisture-resistant. Nordic spruce is the traditional, affordable Finnish choice. Hemlock offers a clean, near-odourless look at a mid-range price. For allergy sufferers, aspen or basswood are ideal. The best wood depends on your budget, scent preference and where it will be used.
What Makes a Good Sauna Wood?
Not all timber suits the heat and humidity of a sauna. The best sauna woods share these qualities:
- Low heat conductivity: soft, low-density woods stay comfortable to touch even at high temperatures, essential for benches.
- Moisture and rot resistance: the wood must handle repeated heat and humidity without warping or decaying.
- Minimal resin and knots: resinous woods can leak sap and knots can become uncomfortably hot.
- Stability: it should resist cracking and warping over years of thermal cycling.
- Aroma and appearance: from the rich scent of cedar to the clean, pale look of aspen, personal preference matters.
Western Red Cedar: The Premium Choice
Cedar is the most popular premium sauna wood for good reason. It is naturally resistant to moisture, decay and warping, has beautiful reddish tones, and releases a pleasant, calming aroma when heated. Its low density means it stays comfortable to touch. The main trade-off is cost, cedar sits at the higher end, but for many it is worth every dirham for the aroma and longevity.
Nordic Spruce: The Traditional Finnish Option
Spruce is the classic wood of authentic Finnish saunas. It is affordable, light in colour and gives a bright, traditional look. Good-quality spruce is a fantastic value choice, though it can contain more knots and resin than cedar, so quality grading matters to avoid sap pockets. It is a popular pick for those wanting an authentic sauna on a sensible budget.
Hemlock: The Clean, Mid-Range All-Rounder
Canadian or Western hemlock offers a smooth, pale, near-knot-free surface with very little aroma, making it ideal for anyone sensitive to strong scents. It sits between spruce and cedar on price and gives a clean, modern appearance. Hemlock is less naturally rot-resistant than cedar, so proper ventilation and care are important, but it remains a reliable, attractive choice.
Excellent Alternatives
- Aspen: pale, knot-free and virtually odourless, a top choice for allergy sufferers and those who dislike strong aromas.
- Basswood: soft, hypoallergenic and scent-free, commonly used in infrared saunas.
- Thermally modified woods: heat-treated spruce or aspen with enhanced stability, rot resistance and a richer, darker tone.
Avoid resinous woods like standard pine for interior benches, as they can leak hot sap.

Frequently Asked Questions
What is the best wood for a sauna?
Western Red Cedar is widely considered the best all-round sauna wood, thanks to its natural moisture resistance, pleasant aroma, stability and comfortable low heat conductivity. However, spruce, hemlock and aspen are all excellent choices depending on your budget and preferences.
Is cedar or hemlock better for a sauna?
Cedar offers superior natural moisture resistance and a rich aroma, making it the premium choice. Hemlock is more affordable, has a clean, near-odourless finish and suits scent-sensitive users, but is less naturally rot-resistant, so it needs good ventilation and care.
What wood is best for sauna benches?
Benches should use soft, low-density woods that stay cool to the touch, such as cedar, aspen or basswood. These woods avoid the discomfort of hot surfaces and resist splintering, making them ideal for direct skin contact.
Which sauna wood is best for allergies?
Aspen and basswood are the best choices for allergy sufferers, as they are virtually odourless and hypoallergenic. They avoid the strong aromas of cedar, which can affect scent-sensitive people, while still providing a durable, comfortable surface.
Can I use pine for a sauna?
Standard pine is not ideal for interior sauna benches because it is resinous and can leak hot sap and has knots that heat up uncomfortably. It may be used for some exterior elements, but cedar, spruce, hemlock or aspen are far better for the interior.
How do I care for sauna wood in Dubai?
Dust and wipe down benches regularly, ensure good ventilation, and apply a suitable wood conditioner or protective oil twice a year to prevent drying in Dubai's climate. Avoid harsh chemicals and bleach, which damage the timber and its finish.
