Frequently Asked Questions
Preparation & Installation
Do I need a concrete foundation or can I use a gravel or wooden base?
A concrete foundation is not strictly necessary. A well-compacted gravel bed, concrete pavers, or a sturdy wooden platform can all work as long as they provide a stable, level, and well-drained surface. The key is to prevent moisture build-up and uneven settling.
How level does the surface need to be for a sauna or hot tub installation?
The surface must be completely level to avoid structural stress, water imbalance, or improper drainage. Use a spirit level to ensure accuracy before placement. Even small slopes can cause discomfort and long-term damage.
What are the recommended base dimensions for a barrel or cubic sauna?
The base should be at least 10–20 cm wider than the sauna’s footprint on all sides. For example, if the sauna is 2m wide by 3m long, aim for a base that is 2.2m x 3.2m to allow working space, airflow, and safe anchoring.
Can I place the sauna or hot tub on an existing terrace or deck?
Yes, if the structure can support the weight. Hot tubs (especially filled with water and people) are extremely heavy. Check the load-bearing capacity of your terrace or consult a contractor to reinforce it if needed.
How much clearance is needed around the unit for ventilation and maintenance?
Leave at least 50 cm (20 inches) of space around all sides for air circulation, maintenance access, and safe operation —especially around stove or chimney areas.
What equipment or tools are needed for on-site installation?
Most ready-to-use units require minimal tools. However, depending on site access and placement, you may need:
● A level and measuring tape
● Wrenches/screwdrivers for adjustments
● A dolly or lifting straps
● Access to a crane or forklift for heavier units
What are the electricity requirements for lighting or electric stoves?
For electric stoves or LED lighting, a dedicated power supply is required:
● Electric saunas: Require proper voltage connection (usually 220–240V).
● Hot tubs with hydro/LED features: May require electrical access.
Always check the power requirements in the product specs.
Does a hot tub require plumbing or can it be filled with a garden hose?
A garden hose is typically all you need. Most hot tubs are self-contained and do not require permanent plumbing. Water can be drained using gravity or a simple pump.
What should I consider when placing a sauna or hot tub near a house or fence?
● Heat and smoke from wood stoves can affect walls and overhangs — keep chimneys clear of any flammable materials.
● Maintain at least 1–2 meters of distance from walls or fences for safety, ventilation, and fire prevention.
● Consider wind direction for smoke dispersal and privacy when in use.
Do I need a permit to install a sauna or hot tub?
Regulations vary by location. Small, mobile units often don’t need a permit, but it’s best to check with your local authorities.
Usage & Operation
How long does it take to heat a wood-fired sauna or hot tub?
● Sauna: Typically takes 30 to 60 minutes to reach 70–90°C (160–195°F), depending on weather, insulation, and stove type.
● Hot Tub: Depending on the water volume and outside temperature, it may take 2 to 4 hours to heat a wood-fired tub to around 37–40°C (98–104°F). Using a lid and stirring the water helps speed things up.
How much wood do I need per session?
● For a sauna, expect to use about 5–10 kg of dry firewood per session.
● For a hot tub, heating from cold may require 20–30 kg or more, especially in winter. Using dry, seasoned hardwood is most efficient.
Can I use a hot tub or sauna in the rain or snow?
Absolutely — and it can be magical! These units are designed for outdoor, all-weather use. Just make sure:
● The stove is protected from direct water (rain cover or roof extension).
● You have non-slip access paths and a towel or robe nearby.
● The water stays clean — use a cover when not in use.
What’s the difference in experience between electric and wood-burning saunas?
● Wood-burning offers a traditional, rustic feel, soft heat, crackling fire sounds, and a natural ritual.
● Electric saunas are easier to operate, heat up faster, and have precise temperature control.
It really comes down to personal preference and lifestyle.
How often can I use the sauna or hot tub for health benefits?
Most people safely enjoy a sauna 2–4 times per week. Some use it daily in moderation.
Hot tubs can also be used regularly — just limit sessions to 15–30 minutes and stay hydrated.
Always consult your doctor if you have health concerns, especially with cardiovascular issues.
How do I properly ventilate a sauna during and after use?
Good airflow is essential. During use, air enters through a vent near the floor and exits near the ceiling.
After use, open the door and vents fully to release humidity and let the wood dry.
This helps prevent mold and keeps the interior fresh.
Is it safe for children to use a sauna or hot tub?
Yes, but with supervision and time limits.
For saunas, keep sessions short (5–10 minutes) and at lower temperatures (around 60°C / 140°F).
In hot tubs, make sure water doesn’t exceed 37°C (98.6°F) and that children don’t overheat or stay in too long.
Can I leave water in the hot tub between uses?
Yes, for a few days or up to a week — if the water is clean and covered.
For longer periods, consider using a filtration system, UV sterilizer, or natural water treatment.
Always drain and clean the tub regularly to prevent bacteria and algae growth.
Are there safety tips I should follow for first-time users?
● Stay hydrated — drink water before
and after.
● Avoid alcohol while using the sauna or hot tub.
● Start with short sessions and lower temperatures.
● Listen to your body — dizziness, headache, or nausea means it’s time to get out.
● Use non-slip steps, especially in winter or after rain.
Maintenance & Care
How often should I clean my hot tub or sauna?
Hot tub: Clean at least every 1–2 weeks if used regularly, or after every few uses. Always clean before long-term storage.
Sauna: Wipe benches and floors after each use to remove sweat and moisture. Deep clean every few months, or more often with heavy use.
What products are safe to use for cleaning wood interiors?
Use mild, non-abrasive cleaners made for natural wood. A mix of warm water and vinegar or baking soda works well.
Avoid harsh chemicals or bleach — they can damage the wood and affect the smell and air quality inside.
How do I prevent mold or mildew in my sauna?
Ensure proper ventilation during and after each use.
Always dry the interior completely by leaving the door open post-use.
Regular cleaning and avoiding wet towels or clothes left inside helps too.
Optional: Add a hygrometer to monitor humidity levels.
Should I drain the hot tub after every use?
Not necessarily. If water is clean and covered, you can leave it for up to a week or more, depending on temperature and usage.
Drain and refill more frequently if used often, especially without a filtration or chemical treatment system.
What’s the best way to winterize a hot tub or sauna?
Hot tubs: If not in use, drain completely, dry all pipes, and cover well.
Saunas: Clean thoroughly, ensure vents are open, and avoid moisture buildup. If heated in winter, ensure insulation is adequate and check the stove/chimney for blockages.
Optional: Use antifreeze in pipes if there's a risk of freezing and you can't fully dry the tub.
Do I need to re-oil or seal the wood? How often?
Yes, especially exterior wood exposed to the elements. Apply a UV-protective oil or wood sealer every 6–12 months, depending on climate.
Interior wood should not be sealed — let it breathe and just clean it regularly.
How do I maintain the stove (wood or electric)?
● Wood-burning stoves: Regularly remove ashes, check for creosote buildup in the chimney, and inspect seals and air vents.
● Electric stoves: Wipe down with a dry cloth, check connections, and avoid water contact.
For both types, check that stones are not cracked and are well-positioned.
What’s the lifespan of a wooden sauna or hot tub?
With proper care, 10–20 years or more is realistic. Lifespan depends on material quality, usage frequency, and maintenance.
Components like heaters or linings may need replacing sooner, while the wood structure can last decades.
Can the fiberglass or internal lining be repaired if damaged?
Yes — minor cracks or chips in fiberglass linings can be repaired with patch kits or professionally refinished.
Always act quickly to prevent water leakage or further damage.
Are there maintenance tasks I should do seasonally?
Spring/Summer: Clean, inspect for leaks, oil the wood, test all electrical components.
Fall/Winter: Winterize if not in use, check insulation, clean stoves/chimneys, protect against snow or rain.
Always inspect seals, doors, and moving parts for wear.
Traditions, Tips & Rituals
What’s the best way to structure a sauna session for beginners?
● Start with a quick shower to cleanse the body.
● Enter the sauna and stay for 8–15 minutes, depending on comfort.
● Cool down outside or with a cold shower/dip.
● Rest for 10–15 minutes, hydrate, and repeat 2–3 times if desired.
● Finish with a final rinse and rest wrapped in a towel or robe.
Are there recommended essential oils or herbs to use in the sauna?
Popular options: Eucalyptus, peppermint, pine, lavender, or citrus oils.
Always dilute oils in water before pouring them on stones.
You can also use natural herbs or dried bundles like chamomile, thyme, or mint in a bowl for a gentle aroma.
What’s the health benefit of alternating between hot and cold?
This contrast boosts circulation, reduces inflammation, enhances immunity, and invigorates the body.
It can also relieve sore muscles and improve mental clarity. The “hot-cold-hot” cycle is central to traditional sauna therapy.
Is it better to use the sauna in the morning or evening?
Morning use energizes and wakes the body.
Evening use helps with relaxation and sleep.
Choose what fits your lifestyle — just avoid intense sessions immediately after meals or alcohol.
What should I drink before and after a sauna or hot tub session?
● Water is essential — drink plenty before, during breaks, and after.
● Light herbal teas or electrolyte drinks are also good options.
● Avoid alcohol or sugary drinks, which can dehydrate or disrupt the body's natural responses.
Is it common to go into the snow or cold water after sauna?
Yes — it’s a beloved tradition in Nordic countries!
Jumping into snow or a cold plunge stimulates circulation, boosts endorphins, and feels incredibly refreshing.
Just ensure you’re healthy and warm up again quickly afterward.
Should I use a towel in the sauna or sit directly on the bench?
Always bring a clean towel to sit or lie on — it’s more hygienic, protects the wood, and feels more comfortable.
In traditional settings, this is considered basic sauna etiquette.
How long should I soak in a hot tub for maximum benefit?
Ideal soaking time is 15–30 minutes. Longer stays can lead to overheating or dehydration, especially in hotter
water.
Listen to your body — exit if you feel dizzy, too warm, or fatigued.
Can I turn my sauna or hot tub into a full relaxation experience?
Absolutely! Enhance your session with:
● Dim lighting or candles
● Relaxing music or nature sounds
● Essential oils or natural aromas
● A cozy robe, tea, and a quiet resting spot afterward
● Add in a face mask, body scrub, or gentle stretching to make it a mini spa
retreat right at home.
