Materials & Construction

Every material is carefully chosen to look exceptional and to stand up to the unpredictable British climate, giving you total peace of mind that your outdoor sauna is built to last.

40mm ThermoWood Walls: Built from 40mm thick, top-tier thermally modified Nordic timber, the Viva 250 delivers incredible natural insulation and stability. This advanced heat treatment means the entire structure remains completely rigid and weather-resistant throughout the seasons, with zero risk of warping.
Two-Tier Social Benches: The interior layout features a beautiful two-tier seating system. The top bench offers an extra-deep 620mm space designed for ultimate relaxation, while the lower 400mm bench gives you excellent flexibility for guests who prefer slightly milder temperatures.
Architectural Slatted Exterior: Our signature vertical slatted finish creates a striking, contemporary architectural statement while allowing for natural airflow to keep the external timber in perfect condition.
Full-Height Panoramic Glass: A full-height toughened glass door with matching large side windows floods the cabin with natural daylight, giving you a wonderful view of your garden while keeping a completely airtight seal against the elements.
Integrated Rainwater Management: To keep the cabin perfectly protected from heavy downpours, the heavy-duty EPDM rubber roof comes complete with an integrated drainage system designed to channel rainwater away efficiently.

Delivery & Installation

When you choose Aquasun, you get a completely seamless, end-to-end service. Our own factory-trained installation teams manage the delivery and assembly of your Viva 250, ensuring that your high-end outdoor sauna is set up to absolute perfection and ready for its first session.

What our service includes:

Complete structural assembly of the Viva 250 on your pre-prepared, level base.
Fitting the modern vertical slatted timber exterior cladding panels.
Careful installation of the panoramic toughened glass frontage and all internal fittings.
Physical setup of your high-performance sauna heater and the dimmable lighting system.

Important Electrical Note: Please keep in mind that while our building crew looks after the entire physical construction and fits the hardware, a fully certified electrician must carry out the final live connection to your property’s power supply. We usually recommend a dedicated 32A or 40A circuit to match your chosen heater for optimal performance.

Standard Features & Extras

The Viva 250 is a beautifully engineered solution for social wellness, perfectly combining striking modern architecture with a genuinely spacious interior. It comes out of the box with an excellent line-up of standard features, along with a variety of ways to customise your private garden retreat.

✔ Sociable Seating Layout: The dual-tier bench system with integrated backrests easily fits families or groups of up to five people with total comfort.

✔ Abundant Natural Light: The full-height tempered glass door and matching side windows completely fill the 8.6 cubic metre interior with gorgeous garden views.

✔ Advanced Air Circulation: Designed with a high-performance triple ventilation system (inlet, outlet, and exhaust) to keep the air fresh and control moisture perfectly.

✔ Built for the Elements: Engineered with premium 40mm ThermoWood and a reinforced base frame to handle demanding outdoor conditions all year round.

Tailored Upgrades: You can add your own personal touch to the Viva 250 by choosing a decorative hexagonal feature wall at the back, installing atmospheric dimmable LED lighting strips beneath the benches and backrests, or opting for the smart UKU WiFi control system so you can start heating it up directly from your phone.

Benefits of Saunas

Detoxification

Saunas help your body naturally flush out toxins through sweating. As your core temperature rises, blood vessels expand, circulation improves, and your body releases built-up impurities through the skin.

Regular sessions can leave you feeling lighter, refreshed, and cleansed — a simple yet powerful way to support your body’s natural detox process.

Muscle Recovery & Pain Relief

Heat therapy relaxes muscles, eases tension, and improves blood flow to tired or sore areas. This can reduce stiffness and speed up recovery after exercise or physical work.

It’s also known to help with chronic pain conditions such as arthritis or back pain, offering soothing, drug-free relief.

Stress Reduction & Mental Clarity

The gentle heat of a sauna helps calm the nervous system and reduce stress hormones like cortisol. The quiet, warm environment encourages deep relaxation and mindfulness.

Many people report clearer thinking and an improved mood after each session — like a mental reset for the body and mind.

Improved Circulation & Heart Health

Sauna use mimics the effects of light cardiovascular exercise. As your heart rate rises and blood vessels expand, circulation improves and oxygen delivery to muscles and organs increases.

Research suggests that regular sauna bathing may support heart health, helping lower blood pressure and improve vascular function over time.

Skin Health & Glow

The heat from a sauna opens pores and boosts blood flow to the skin, promoting natural cleansing and cell renewal.

After each session, you’ll notice a healthy glow as impurities are flushed out and new, oxygen-rich blood nourishes the skin’s surface.

Better Sleep & Recovery

A sauna session before bed can help your body wind down for a deeper night’s rest. As your core temperature cools afterwards, it signals your body to enter sleep mode naturally.

Combined with its relaxation benefits, sauna use can improve sleep quality, leaving you feeling restored and energised the next morning.
