1 ✅ Pre-Sauna Preparation

For the best sauna experience and to prevent unnecessary wear and tear, follow these essential steps before each session:

1.1 🚿 Dry Off Before Entering

1.1.1 🛡️ Preserving the Sauna

If you've just showered, exited a cold plunge tub, or completed an ice bath, thoroughly towel off before stepping into the sauna.

Why? Entering the sauna while wet increases humidity, causing moisture absorption into the wood. This can lead to:

1. Swelling & warping of the wood 🌊

2. Long-term structural damage 🏗️

3. Unwanted odour accumulation over time 👃

Many wellness resorts and commercial wellness centres offer both cold plunge tubs and saunas. While it’s perfectly fine to use both, always briefly dry off to maintain sauna integrity and prevent excessive moisture build-up.

1.1.2 🔥 Maximising Sauna Effectiveness

If you’re taking a shower or bath beforehand, it’s best to thoroughly towel off before entering the sauna. This helps in two key ways:

1. It prevents excess moisture from affecting the sauna’s humidity levels. 

2. Dry skin allows your body to begin sweating more efficiently. If your skin is still wet, initial sweat production may be delayed, as external moisture can interfere with the body's natural cooling process.

 

1.2 💨 Ensure Proper Ventilation

Saunas are designed for controlled heat circulation—keep ventilation points clear to maintain proper airflow and prevent excessive moisture build-up.

If the sauna has been in use for several hours, leave the door open for a short period afterward to:

1. Recirculate fresh air 🔄

2. Remove excess humidity 🌬️

3. Preserve the quality of the interior wood 🪵

A well-ventilated sauna reduces the risk of mould growth and ensures an even, comfortable heat distribution.

 

1.3 🔥 Gradual Heating Is Best

Avoid immediately setting the sauna to its maximum temperature. Sudden heat surges can cause materials to expand too quickly, leading to premature wear and potential damage.

   

1.4 🏖️ Seating Position & Protection

Always sit on a sauna towel or mat to protect the wood from excessive sweating and moisture build-up.

Especially important after: 🚿 A shower | ❄️ A cold plunge | 🌊 An ice bath

Why? Sitting directly on the wood can lead to:

1. Moisture absorption and premature wear 🚫💦

2. Bacteria build-up and lingering odours 🦠

3. Discoloration and damage over time 🎨⚠️

Avoid placing heavy or sharp objects directly onto the wooden benches, as this can cause indentations or surface damage.

 

By following these simple yet crucial pre-sauna steps, you'll enhance your overall experience while keeping your sauna in top condition for years to come! 🔥♨️

 

2 ⏳ Sauna Operating Hours & Usage Recommendations 

2.1 🏡 Home & Personal Use

2.1.11️⃣ Recommended Sauna Sessions:

1. Aim for 2-5 sauna sessions per week, depending on your personal preference, fitness level, and tolerance to heat.

2. If you're new to sauna use, start with 1-2 sessions per week and gradually increase as your body adapts.

3. Regular sauna use can help with relaxation, improved circulation, and muscle recovery.

 

2.1.2 2️⃣ Typical Session Length: ⏳

1. Each sauna session should last 15-30 minutes to allow your body to acclimate to the heat while avoiding unnecessary strain.

2. If you're a beginner, start with shorter sessions (10-15 minutes) and gradually build up your tolerance.

3. Listen to your body—if you feel lightheaded or uncomfortable, exit the sauna and cool down immediately.

 

2.1.3 3️⃣ Maximum Daily Use: 🚫

1. The recommended daily sauna use is up to 2 hours total per day, divided into multiple sessions if necessary.

2. Avoid excessive sauna use as it can lead to dehydration, dizziness, and excessive fatigue.

3. Always rehydrate after each session with plenty of water and electrolytes to replenish lost fluids.

 

2.1.4 4️⃣ Rest Periods & Cooling Breaks: ❄️

1. It's essential to take cooling breaks between sauna sessions to prevent overheating.

2. Step into a cooler environment, take a lukewarm or cold shower, or sit outside for 5-10 minutes before re-entering.

3. Allow your heart rate and body temperature to stabilize before starting another session.

4. For contrast therapy, alternating between sauna heat and cold plunges can help improve circulation and recovery, but always dry off completely before re-entering the sauna to prevent excessive moisture build-up.

 

Following these best practices will maximise the health benefits of sauna use while preventing overuse-related issues. Always listen to your body and adjust your sessions accordingly to maintain a safe and enjoyable sauna experience. 🔥💆‍♂️

 

2.2 🏢 Commercial Use (Gyms, Spas, Wellness Centres, etc.)

2.2.1 ⏳ Standard Industry Operating Hours

1. The standard operating hours for commercial saunas are 40 hours per week (8 hours per day, 5 days per week).

2. Running the sauna beyond this schedule accelerates wear and tear on the wood, heating elements, and electrical systems.

3. Overuse without proper precautions can lead to expensive repairs and reduced lifespan of the sauna.

 

2.2.2 🔥 Continuous Use Guidelines

1. Do not exceed 8 consecutive hours of sauna operation without a cooldown period.

2. Repeated heating and cooling cycles cause wood expansion and contraction, leading to potential cracks, warping, and stress on fastenings.

3. Electrical components such as heaters and control panels may overheat if the sauna runs continuously without rest periods.

 

2.2.3 ❄️ Rest Periods & Cooldown Breaks

1. Allow 30-60 minutes of cooldown after long operational sessions to regulate temperature and prevent overheating.

2. In high-use environments, schedule a cooldown period every 4 hours to prevent excessive material stress and degradation.

3. Keeping the sauna properly ventilated during cooldown periods will prolong its structural and electrical integrity.

 

2.3 🔥 Ensuring Optimal Performance & Longevity for High-Use Saunas

Our saunas are built for commercial use and designed to withstand long-term operation in businesses such as gyms, wellness centres, and spas. However, it’s important to recognise that the term “commercial use” does not refer to unlimited, continuous operation. Instead, it aligns with standard industry usage—typically 8 hours per day, 5 days per week.

Many of our commercial customers, including gyms and wellness centres, successfully operate within these guidelines and experience years of trouble-free sauna use. However, exceeding these usage recommendations—such as running the sauna 12+ hours daily, 7 days a week—pushes the materials and components beyond their intended design limits. This does not mean the sauna is unfit for commercial use; rather, it highlights the importance of operating within designed capacity or making structural modifications for extreme use cases.

 

2.3.1 ⚠️ What Happens When Saunas Are Overused?

Excessive sauna operation without cooldown periods can result in accelerated wear due to continuous exposure to high temperatures.

Unlike electrical appliances, saunas—particularly those constructed from natural materials like wood—do not degrade on a linear timeline (i.e., twice the use does not simply mean half the lifespan). Instead, thermal fatigue compounds over time, leading to exponentially faster wear.

 

The table reveals potential consequences of running a sauna for ~70 hours per week, particularly when lacking proper care and maintenance:

 

2.3.2 🔧 Why Cooldown Periods Matter

Heat affects wood much like stress affects metal—when force is applied without relief, fatigue sets in faster. Sauna materials naturally expand and contract under heat. Allowing time for cooldown cycles preserves the structural integrity of the sauna, ensuring years of trouble-free use.

🔹 What Happens When a Sauna Runs For ~70 Hours Per Week Without Rest?

1. Wood loses elasticity – Sauna panels and beams lose their natural flexibility, leading to permanent deformation.

2. Accelerated drying – Continuous heat exposure removes essential moisture from the wood, making it brittle and prone to cracking.

3. Structural joints weaken – Expansion without contraction loosens beams, fasteners, and panelling.

Most high-traffic commercial saunas include natural rest periods (such as between client sessions) to prevent compounded thermal fatigue. Without these breaks, materials experience significantly faster degradation.

 

2.4 🛠️ Tailored Solutions for High-Use Commercial Environments

If your business requires a sauna to run for longer hours than standard commercial usage, we highly recommend structural modifications to handle the additional thermal stress.

🔹 Custom Reinforcements Include:

1. 🔥 Upgraded high-heat resistant wood in critical areas like the ceiling and near the heater, where heat exposure is highest.

2. 🌬️ Enhanced ventilation systems to prevent moisture build-up and regulate temperature fluctuations.

3. ⚡ Upgraded electrical components designed for high-intensity commercial use.

4. 🔩 Reinforced internal fixings to prevent fixtures (like lighting or control panels) from loosening due to heat expansion.

 

2.5 🛠️ Ensuring Long-Term Durability

Proper maintenance and responsible usage are essential for extending the life of your sauna and maintaining optimal performance.

By implementing a structured maintenance routine and adhering to best practices, you can prevent costly repairs, maintain efficiency, and ensure a safe sauna experience. Follow these key guidelines to keep your sauna in excellent condition for years to come:

  

2.6 ✅ Final Thoughts: Maximising Your Sauna’s Performance

Our saunas are built to commercial standards, providing exceptional performance and longevity when maintained correctly. While operating within standard usage guidelines (40+ hours per week) ensures years of reliable use, exceeding 70+ hours per week requires additional considerations.

To protect your investment and ensure long-term functionality, we recommend:

1. ✅ Following operational best practices with planned cooldown periods.

2. ✅ Scheduling routine maintenance to inspect heating elements, ventilation, and structural integrity.

3. ✅ Consulting us for reinforced sauna models if extended continuous operation is required.

By taking a proactive approach, you can enjoy a high-performing, durable sauna tailored to your commercial needs. 🔥♨️

If your sauna is installed outdoors, exterior protection is absolutely essential. Exposure to rain, wind, UV rays, and temperature fluctuations can cause cracking, fading, warping, and water damage if not properly maintained.

Applying protective treatments and conducting regular inspections will extend the lifespan of your sauna and prevent costly repairs. This is particularly important for saunas installed near the coast and in areas with that are more exposed to the elements.

Notes:

a) This is particularly important for saunas installed near the coast and in areas with that are more exposed to the elements.

b) If you sauna was pre-painted by us in the factory, section 3.4 does not apply. Instead, simply repaint every 12-24 months.

 

3.4.1 🔧 Key Steps for Exterior Care:

1️⃣ Apply Rustin's Yacht Varnish Immediately After Installation 🏗️

1. Protection should begin as soon as the sauna is installed—ideally on the same day or within a few days.

2. Early application of varnish creates a protective barrier against moisture and prevents UV exposure, which can weaken the wood over time.

3. Without early treatment, outdoor saunas are vulnerable to premature aging, swelling, and surface damage.

2️⃣ Check the Weather Forecast Before Applying ☀️🌧️

1. The varnish requires a dry environment to cure properly. Applying it before rain or in high humidity can compromise the protective seal, leading to ineffective coverage.

2. Choose a clear, dry day with moderate temperatures for best results.

 

3️⃣ Conduct Regular Exterior Inspections 🔍

1. Every 6 months, inspect your sauna’s exterior panels, roof, and doors for cracks, dullness, peeling, or signs of weather exposure.

2. Address minor issues immediately to prevent more significant damage.

 

4️⃣ Reapply Varnish Annually (or As Needed) 🖌️

1. Annual reapplication is generally sufficient for most outdoor saunas.

2. For saunas in harsher environments, such as coastal areas or open countryside, more frequent applications (every 6-9 months) may be required due to stronger winds, salt exposure, and high moisture levels.

3. For sheltered or inland saunas, yearly maintenance is usually enough to maintain effective protection.
