the complete guide to setting up a home sauna routine

Q: How much does it cost to run a home sauna in Australia?

At the national average electricity rate of $0.28 per kWh, a 30-minute infrared session costs roughly $0.21-$0.42, and a 2-person infrared sauna used daily adds around $102 a year to a power bill. Traditional electric saunas cost noticeably more to run, since the heater has to warm the whole room rather than just the person inside it.

the complete guide to setting up a home sauna routine

A home sauna setup is really two projects in one. The first is physical: choosing a sauna, finding the right spot for it, and working out what you actually need on hand. The second is the one most guides skip – building a routine you're still doing in six months.

Key takeaways:

In 2023, home installations made up 46% of global sauna and spa equipment sales – still the largest single category as the market grows toward USD 6.4 billion by 2035 (Global Growth Insights, 2026).
In Australia, infrared saunas cost roughly $0.21-$0.42 per 30-minute session at the national average electricity rate – traditional electric saunas cost noticeably more to run, since they heat the whole room rather than just the person inside it (Inner Light Sauna, 2026).
A 20-year Finnish cohort study linked sessions over 19 minutes to a 52% lower risk of sudden cardiac death (Laukkanen et al., JAMA Internal Medicine, 2015).
2-4 sessions a week, 15-20 minutes each, at a consistent time, is the routine most people sustain – and roughly the dose tied to the strongest cardiovascular outcomes.

In 2023, home installations already made up 46% of global sauna and spa equipment sales, and the market is projected to grow from USD 4.16 billion in 2025 to USD 6.4 billion by 2035 (Global Growth Insights, Sauna and Spa Market Size, Trends & Outlook 2026-2035, 2026). More people are bringing sauna home than ever before – but a sauna that sits unused in the garage isn't a wellness practice. It's an appliance.

This guide covers both halves: how to choose, install, and stock your home sauna, and how to turn it into something you actually return to, two or three times a week.

what does “setting up” a home sauna routine actually involve?

Most home sauna guides stop at installation: pick a unit, find a spot, wire it in, done. That's necessary, but it's the easier half of the job. The harder half is what happens after the install – whether the sauna becomes something you use most weeks, or something that quietly turns into storage space.

Most of the early conversations we have with customers about home setups aren't really about the sauna itself. They're about logistics – where it'll go, how it fits around a household's routine, and what's actually worth having on hand before the first session rather than after.

That's the order this guide follows. We'll start with the physical decisions – sauna type, location, and the handful of things worth keeping nearby – then move into the part that actually determines whether the setup gets used: the session itself, and the weekly rhythm around it.

Think of “setup” as the one-time decisions, and “routine” as the ongoing practice. Get the first part right, and the second part gets a lot easier to stick with.

infrared or traditional: which home sauna suits your space?

The first real decision is infrared versus traditional, and it comes down to space, budget, and the kind of heat experience you're after – not just which one is cheaper to buy.

Infrared saunas heat your body directly using infrared light, rather than heating the air around you. They run at lower temperatures, roughly 50-65°C compared with 70-90°C for traditional saunas (Inner Light Sauna, Infrared Saunas vs Traditional Saunas – Which One is Better?, 2026), are ready to use in 10-15 minutes, and have a smaller footprint – many fit into a spare room or even a large bathroom. They're also the cheaper option to run: in Australia, a 30-minute infrared session costs around $0.21-$0.42 at the national average electricity rate of $0.28/kWh, and a 2-person unit used daily adds roughly $102 a year to a power bill (Inner Light Sauna, How Much Does It Cost to Run an Infrared Sauna?, 2026).

Traditional electric saunas heat the air in the whole room rather than just the person inside it, which is why they run hotter and cost more to operate. They deliver the higher-heat, higher-humidity experience most people picture when they think “sauna.” They also need more ventilation planning and a longer warm-up.

Barrel saunas and outdoor cabins are usually traditional or wood-fired units housed in a standalone structure. They suit larger backyards and can handle higher temperatures, but bring their own weatherproofing and access considerations – worth factoring in if you're planning for an Australian summer as well as winter.

If you're still weighing this up, we've put together a full side-by-side comparison of infrared and traditional saunas for home use, covering running costs, install complexity, and the experience differences in more depth.

where should you install your home sauna?

Wherever you put it, three things matter more than the room itself: a flat, level surface, a dedicated electrical circuit, and proper ventilation. Get those right, and almost any space – a spare bathroom, a garage corner, or a covered section of backyard – can work.

Electrical setup. Most home saunas need a dedicated circuit, and in Australia, that means a licensed electrician for the final connection – not just for compliance, but because an undersized circuit is one of the most common reasons home saunas underperform or trip breakers mid-session.

Ventilation and moisture. Saunas produce a lot of humidity, even infrared ones. Indoor installations need moisture barriers on walls and ceilings to protect drywall, plus some form of airflow – a vent, an extractor fan, or simply a door that can be left ajar between sessions.

Flooring. Tile, stone, or sealed concrete handle moisture far better than carpet or untreated timber. If you're converting a room that wasn't built for it, flooring is often the first thing that needs addressing.

Outdoor and Australian climate considerations. Outdoor cabins and barrel saunas need weatherproofing that accounts for both ends of the Australian climate – UV exposure and heat in summer, damp in winter, particularly in coastal areas like Sydney, Melbourne, and Perth, where humidity and salt air can affect untreated timber over time.

Whichever room you choose, walk through it once with the finished sauna in mind: where the door swings, where you'll sit afterwards to cool down, and whether the space still works once it's warm and humid rather than empty and cold.

building your sauna kit: what you actually need

You don't need much to get started – a couple of towels, water, and something to protect your head are the only genuine essentials. Everything else is a nice-to-have you can add once the basics are routine.

Two towels. One to sit on – this matters at home as much as in a public sauna, since sweat and oils build up on benches over time – and one to dry off with afterwards.

Water. A bottle kept near the sauna, not in the kitchen. You'll lose more fluid than you expect, even in a 15-minute session, and having water within reach makes it far more likely you'll actually drink it.

A sauna hat. Your head is the most heat-sensitive part of your body, and it's often the reason sessions get cut short before the benefits kick in. A 4mm Merino wool hat insulates your head from the hottest air near the ceiling, the layer that hits your scalp first and hardest, so the rest of your body has more time to settle into the heat. We go into the full mechanism – and what to look for in a hat – in our guide to the benefits of a sauna hat. If you're shopping for one, both the Modern and the Classic are made from 4mm Australian Merino wool felt.

A timer. Not essential on day one, but useful once you're tracking session length against the routine in the next section.

Once your hat needs a refresh, a little care goes a long way – Merino wool barely needs washing at all, and our care guide covers how to keep one in good shape for years.

This is also where it's worth thinking about the kit as part of the routine, not just a one-off shopping list. The things you reach for each session – towel, water, hat – are what make the routine frictionless enough to actually repeat. We've put together a complete accessories checklist if you want the fuller picture beyond these essentials.

your first session: heat, cool, repeat

Most home sauna sessions follow the same basic shape: preheat, a quick shower, a round of heat, a cool-down, and then – if you're up for it – a second round.

Preheat and shower. Give the sauna time to reach temperature while you take a quick shower. This rinses off lotion, sunscreen, and the day's sweat, and helps your pores open up before you start.

Round one. Start on the lower bench, where it's milder, and aim for 5-10 minutes. You're not testing your limits here – you're letting your body get used to the heat. A light sweat by the end of the round is a good sign.

Cool down. Step out, and let your body temperature come back down – a cool shower, a few minutes in fresh air, or a cold plunge if you have one. This phase matters as much as the heat itself, and it's where your heart rate settles and the first wave of relaxation kicks in.

Round two (optional). If you're feeling good, go back in for another 10 minutes or so. Some people notice the “sauna glow” after this second round – a kind of loose, clear-headed calm that tends to be the reason people come back.

If this is your first time using a sauna at all – at home or otherwise – our beginner's guide to sauna walks through this in more detail, including what to expect, how your body responds, and basic safety guidance for new sauna users.

How hot should it be for that first session? Lower than you think. Start at the bottom of your sauna's temperature range and build up over a few sessions rather than going straight for the highest setting.

designing your weekly sauna routine

Once the first few sessions feel comfortable, the question shifts from “how do I do this” to “how often should I do this” – and the answer matters more than people expect.

Most healthy adults land on 2-4 sessions per week, 15-20 minutes each, as the routine that delivers the strongest health outcomes without becoming a chore (Mayo Clinic Proceedings, Laukkanen et al., Cardiovascular and Other Health Benefits of Sauna Bathing: A Review of the Evidence, 2018). In a 20-year Finnish cohort study of over 2,300 men, those who used a sauna 2-3 times a week had a 38% all-cause mortality rate over the study period, against 49% for once-a-week users – roughly a 22% reduction – and the 4-7 times a week group fared better again, with lower rates of death from cardiovascular disease and stroke as well (Harvard Health Publishing, Sauna use linked to longer life, fewer fatal heart problems, 2015).

Pick a day and time, and protect it. Consistency matters more than intensity. A 15-minute session on the same two evenings each week beats an occasional hour-long session that only happens when the mood strikes.

Morning or evening? Both work, and it depends on what you're using the sauna for. An evening session can help with wind-down – in a global survey of sauna users, 83.5% reported improved sleep after sauna bathing (Hussain et al., A hot topic for health: Results of the Global Sauna Survey, Complementary Therapies in Medicine, 2019). A morning session tends to suit people using sauna as part of a recovery or training routine.

Start small and build. One or two sessions a week for the first month is plenty. Add a third once the routine feels established rather than effortful.

etiquette and safety for a home sauna

It's tempting to think etiquette only applies to public saunas, but a home sauna usually means sharing the space with family, housemates, or guests – and a few of the same habits still matter.

Household scheduling. If more than one person in the house wants to use the sauna, a loose schedule avoids the “is anyone in there” back-and-forth. It also means the sauna gets used more consistently, which is most of the battle.

Basic hygiene still applies. Shower before and after, and keep a towel on the bench – even at home, oils and sweat build up over repeated use, and a quick rinse beforehand makes the air noticeably more pleasant for whoever uses it next.

Guests and first-timers. If you're introducing someone to your home sauna for the first time, treat it like their first session anywhere – shorter rounds, lower temperatures, and a clear explanation of where the water and exit are. Our sauna etiquette guide covers the broader unwritten rules, and most of it applies just as well with guests in your own home.

Safety basics that don't change at home. People with cardiovascular conditions, uncontrolled high blood pressure, or who are pregnant should check with a doctor before regular sauna use (Medical News Today, 2023). Drink water before, during, and after. If anyone feels dizzy, nauseous, or unwell, they should exit and cool down immediately – there's no reason to push through it, at home or anywhere else.

making it a practice that lasts

The goal isn't a perfect setup. It's a routine you keep returning to – and the two aren't the same thing.

It's easy to spend weeks researching the “right” sauna, the ideal room, the ideal accessories, and end up with a setup that's technically perfect but rarely used. A simpler setup that gets used three times a week beats an elaborate one that gets used three times a year.

Once the basics are in place – sauna, towel, water, somewhere to cool down – the rest is optional layering. Some people add music or silence, aromatherapy, or a few minutes of breathwork during the cool-down. None of it is necessary, but it's the kind of detail that turns a routine into something you look forward to rather than something you schedule around.

That's really the idea behind a home sauna routine: a practice simple enough to repeat, and considered enough to actually enjoy. A well-made sauna hat, a towel that's always in the same spot, and a time slot that's actually yours – small, repeatable details add up to something that lasts a lot longer than any single “perfect” session.

home sauna setup: frequently asked questions

How long should a home sauna session be?

Most healthy adults do well with 15-20 minute sessions, though beginners should start at 5-10 minutes and build up gradually (Mayo Clinic Proceedings, Laukkanen et al., 2018). Infrared sessions can run slightly longer – up to 30 minutes – given the lower operating temperature.

How often should you use a home sauna?

2-4 sessions per week is the range most commonly linked to better long-term health outcomes, with people using a sauna 4-7 times weekly showing the lowest all-cause mortality and the lowest rates of cardiovascular death in a 20-year Finnish cohort study (Harvard Health Publishing, 2015). Starting with 1-2 sessions a week and building up is a realistic way in.

What temperature should I set my home sauna to?

Traditional saunas typically run at 70-90°C, while infrared saunas operate at a lower 50-65°C (Inner Light Sauna, Infrared Saunas vs Traditional Saunas – Which One is Better?, 2026). Beginners should start at the lower end of either range and increase gradually as heat tolerance builds.

Do I need a sauna hat for a home sauna?

It's not required, but it's one of the most useful additions for sessions over 10 minutes. A 4mm Merino wool hat insulates your head from the hottest air near the ceiling, the layer that tends to make sessions feel too intense too soon – our guide to the benefits of a sauna hat covers the full reasoning.

Is an infrared or traditional sauna better for a home setup?

It depends on space, budget, and the experience you want. Infrared saunas cost roughly $0.21-$0.42 per 30-minute session, heat up faster, and need less space (Inner Light Sauna, 2026), while traditional saunas deliver the higher-heat, higher-humidity experience at a noticeably higher running cost, since they heat the whole room rather than just the person inside it.

How much does it cost to run a home sauna in Australia?

At the national average electricity rate of $0.28/kWh, a 30-minute infrared session costs roughly $0.21-$0.42, and a 2-person infrared sauna used daily adds around $102 a year to a power bill (Inner Light Sauna, How Much Does It Cost to Run an Infrared Sauna?, 2026). Traditional electric saunas cost noticeably more to run, since the heater has to warm the whole room rather than just the person inside it.
