Sauna lighting is about much more than simply making a room bright. The right lighting can transform your sauna into a relaxing space where design, comfort and atmosphere come together. From a soft, warm glow and elegant indirect lighting to beautiful Starry Sky effects, modern sauna lighting offers many possibilities.
One Finnish company bringing these ideas to life is Cariitti. With many years of experience in lighting design and manufacturing, Cariitti creates lighting solutions that combine functionality, quality and Scandinavian design. Its products are designed especially for saunas, bathrooms and spa environments, helping to create comfortable and visually beautiful spaces.
Cariitti is a Finnish family-owned company with a strong focus on bringing light and comfort into different environments. Over the years, it has developed a versatile collection ranging from subtle LED and fibre optic lighting to decorative lighting elements.
In 2018, Cariitti introduced its own TAIVE collection, which was later expanded with TAIVE Sauna Cabins in 2023. The company is also proud of the Finnish Key Flag Symbol (Avainlippu), which recognises products and services that meet the requirements for Finnish origin.
Whether you are planning a private home sauna or a larger wellness space, Cariitti offers different lighting possibilities to help create an atmosphere that reflects your style and needs.
Different Types of Sauna Lighting
Choosing the right lighting depends on the atmosphere you want to create, the layout of your sauna and the features you need. Here are some popular sauna lighting ideas to consider.
1. Indirect Sauna Lighting
Indirect lighting is one of the most popular choices for modern saunas. Instead of shining directly into the room, the light is reflected from surfaces, creating a soft and comfortable atmosphere. LED strips can be installed behind backrests, underneath benches or along the ceiling. This creates a beautiful lighting effect without making the light too bright or disturbing.
Cariitti's Sauna Ultra Ambient range offers solutions for indirect ceiling lighting. The products are designed to withstand significant temperature changes and operate in temperatures ranging from -40°C to +125°C. Different versions are available, including White, Tunable White and RGBW, giving you the opportunity to choose between simple white lighting, adjustable white tones or colour-changing effects.
2. Sauna Bench Lighting
Lighting underneath or behind sauna benches can make a big difference to the overall appearance of the space. LED lighting installed beneath the benches creates a floating effect and adds depth to the interior. It can also help improve visibility when moving around the sauna.
Depending on the design, you can choose subtle lighting that blends into the interior or more decorative solutions that highlight the shape and structure of the benches.
3. Starry Sky Sauna Lighting
If you want to create something special, a Starry Sky lighting system is an elegant option. Fibre optic lighting creates small points of light in the ceiling, giving the impression of a beautiful starry sky. It is a great way to add a relaxing and luxurious feeling to your sauna.
Cariitti offers several Starry Sky options:
- Starry Sky: A classic starry sky effect.
- Starry Sky Twinkle: Fibre optic points create a subtle sparkling effect.
- Starry Sky Crystal: Decorative crystals add extra sparkle and elegance.
- Starry Sky Crystal Twinkle: Combines sparkling fibre optics with decorative crystals.
These solutions are also available for selected spa environments. Always check the temperature and installation requirements of the specific product before choosing it for a sauna.
4. Decorative Lighting and Accessories
Sauna lighting does not have to be limited to LED strips and ceiling lights. Small details can also make the space more personal and visually interesting.
Cariitti offers different lighting products and accessories, including:
- GLOW illuminated sauna bucket: A decorative illuminated bucket that adds a unique detail to the sauna.
- Aspectu combined meter: A practical combination of a thermometer and hygrometer.
- ECLIPSE lighting: A stylish lighting solution for sauna interiors.
- Sauna Linear LED: Linear LED lighting designed for sauna environments.
These products combine practical features with decorative design, helping you create a sauna that feels complete.
