Overview
Dimensions: 210(D) x 241(W) x 246.5(H)cm Full Specification
The Signature 240 is part of our flagship range of outdoor saunas, designed in the UK and built to thrive in the toughest coastal conditions. From the materials to the engineering, every detail has been considered — with a focus on durability, performance, and timeless design.
Manufactured in Europe under strict quality control, this sauna features powder-coated stainless steel fittings throughout, offering superior resistance to rust, salt, and changing weather. Even the screws and nails are stainless — because shortcuts aren’t part of our process.
Internally, the Signature 240 is finished in Grade A Thermo Aspen — a virtually knot-free, smooth-grain hardwood that looks incredible and is ideally suited to sauna interiors thanks to its low resin content, excellent thermal stability, and resistance to cracking under heat.
Externally, it’s cladded in thick, outdoor-grade burnt wood (also known as shou sugi ban), which is naturally weather-resistant and requires virtually no ongoing maintenance. This charring process gives the sauna a bold, premium finish that holds up beautifully over time.
The structure is insulated with FF-PIR, the gold standard in sauna insulation — ensuring consistent heat, energy efficiency, and comfortable use all year round.
New for this model: a galvanised, powder-coated steel base with heavy-duty adjustable legs, offering strength, stability, and long-term resilience — even on uneven terrain.
From the ground up, the Signature 240 has been built without compromise. If you’re looking for the very best in outdoor sauna design, this is it.

19mm Thick Burnt Wood – A Stylish and Durable Exterior for Outdoor Saunas
The 19mm thick burnt wood exterior is a standout feature of our signature saunas, chosen for its sleek, contemporary aesthetic that perfectly complements modern outdoor spaces. More than just visually striking, burnt wood offers exceptional benefits for outdoor sauna cladding. Its natural charring process enhances resistance to weathering, moisture, and pests, making it ideal for year-round outdoor use. This sustainable material is also low maintenance, with its unique texture adding an extra layer of sophistication to the sauna’s design.
Contemporary Cube Design – A Seamless Blend of Luxury and Nature
Our cube-shaped sauna design redefines outdoor luxury with its bold, contemporary structure. The full panoramic front window and corner glass door invite you to fully embrace your outdoor surroundings while enjoying the ultimate sauna experience. Choose between mirrored glass, offering enhanced privacy in certain lighting conditions and a design that blends seamlessly with the environment, or smoked glass, providing a sleek, elegant finish that elevates the overall aesthetic.
The cube design’s expansive glass frontage makes it the perfect statement piece, combining modern architecture with the serenity of nature.
Please note: mirror glass/ mirror tint enhances privacy in certain lighting conditions but does not provide complete privacy. Visibility may vary depending on lighting conditions, including internal lighting and direct sunlight.
Outdoor Sauna With Galvanised Steel Base with Adjustable Legs
The Signature 240, outdoor sauna has been designed to last. Featuring a heavy-duty galvanised steel base, powder-coated in black with heavy-duty galvanised steel adjustable legs.
The lifespan of an outdoor sauna will only last as long as the base; no need to worry about the base rotting in the future. Furthermore, an additional benefit of the base being made of high-quality galvanised steel is that it’s movable. So, if in the future you decide to move house, you can take the sauna with you.
The adjustable legs means that the sauna can even be installed on uneven ground, providing it’s solid and can withstand the weight of the sauna.
Premium Wood Selections – Crafted for Beauty and Performance
Glass fronted outdoor sauna
This is a glass-fronted outdoor sauna, thoughtfully designed so that you can enjoy your outside space whilst embracing the warmth and comfort from the inside of the sauna.
Thoughtfully Designed LED Lighting – Warm Illumination for Ultimate Comfort
Our saunas are equipped with sleek LED lighting that elevates the ambience and enhances the overall experience. Behind the backrest, an elegant LED light gently washes upwards along the back wall, creating a warm, inviting glow. The upper bench features discreet downlighting, offering subtle illumination that perfectly complements the sauna’s luxurious design.
Careful consideration has been given to the placement and direction of the lighting. The LED on the upper bench is strategically positioned to ensure it doesn’t shine into the eyes of those relaxing on the lower bench, prioritising both comfort and functionality. This attention to detail ensures a perfectly lit, soothing environment for every sauna session.

This flexibility ensures that your sauna integrates seamlessly into your environment, combining practicality with luxury.
Efficient Insulation
The Signature 240 Luxury Sauna is designed with exceptional insulation to maximise efficiency and comfort. We use 30mm thick Finnfoam FF-PIR insulation panels with diffusion-proof aluminium laminate, renowned for their superior performance in high-temperature and high-humidity environments—ideal for saunas.
Here are the key benefits:
- Optimal Thermal Performance: The 30mm FF-PIR insulation ensures superior thermal efficiency, allowing the sauna to heat up quickly and retain warmth. Despite its spaciousness, the Signature 200 remains incredibly energy-efficient.
- Temperature Resistance: With a service range of -50°C to +120°C and the ability to temporarily withstand over +200°C, FF-PIR insulation is safe and reliable for sauna conditions.
- Moisture Protection: The aluminium laminate on the FF-PIR panels provides excellent air-tightness and water vapour resistance, preventing moisture penetration and maintaining the insulation’s integrity over time.
- Leak-Proof Design: Seams between panels are sealed with polyurethane foam and heat-resistant tape, ensuring an airtight and efficient structure.
Using 30mm of FF-PIR insulation, the Signature 240 Luxury Sauna guarantees exceptional thermal performance, durability, and energy efficiency. This high-quality insulation enhances your sauna experience and ensures a long-lasting, cost-effective investment.
Health benefits of using a sauna
Over the years, saunas have become a popular choice for those seeking to improve their health and wellness. Let’s face it, saunas feel amazing! And the fact that they’re incredibly good for you is a massive bonus.
Here are some impressive health benefits associated with using a sauna:
- Improved Circulation: As your body temperature rises in the sauna, your blood vessels dilate, increasing circulation. This helps deliver oxygen and nutrients to your muscles and organs while removing toxins and waste products from your body.
- Reduced Stress: Sauna sessions have been shown to lower cortisol levels, helping you feel more relaxed and at ease.
- Enhanced Immune Function: Regular sauna use can boost your immune system, making you less susceptible to illness and infection.
- Better Skin Health: The heat and steam of a sauna open up your pores, allowing your skin to breathe and release toxins. This can lead to clearer, healthier-looking skin.
- Pain Relief: If you suffer from joint pain or muscle soreness, spending time in a sauna can help. The heat increases blood flow to your muscles and joints, relieving pain and stiffness.
So there you have it – just a few of the many health benefits that come with using a sauna. If you’re looking to relax, unwind, and boost your overall health and well-being, investing in a sauna might be just what you need.

Best outdoor sauna in the UK for the price point. It’s not ‘cheap’ but not much is these days, at least that’s worth having. The build quality and attention to detail is incredible, it’s also the first outdoor sauna I’ve seen that has a galvanised steel base with adjustable legs, which I thought was a great idea.
We’re obsessed with our new Signature 200. We use ours at about 85 Celsius which seems to be the ideal temperature for both myself and my wife to use it at the same time. I will generally use the top bench and she will use the lower bench that is a little cooler.
This looks even better in person. It’s a fantastic sauna, and the customer service has been exceptional- thank you.
After spending months looking at saunas online and visiting a few garden centres and showrooms we decided to go for the Signature 200 in the end and glad we did! Product and service has been fab, couldn’t be happier.
Very happy customers x
