After 20 years working across Australian homes, I’ve learned that building design has a bigger impact on your health than most wellness products ever will. So when clients ask about adding a sauna, I look at it through a building science, low tox lens—not a trend-driven one.
A low tox home isn’t about chasing fads. It’s about controlling your environment: materials, air quality, moisture, and how each element behaves over time. And a commonly overlooked piece of a home design conversation is the infrared sauna.
Most People Get “Healthy Homes” Backwards
When people start thinking about healthier living, they usually begin with products—organic food, better cleaning supplies, maybe low-VOC paint during a renovation. And if a sauna even crosses the mind, it’s often treated as an afterthought—“We’ll just put it somewhere after we move in”, or “They’re all the same; just get the cheapest.”
Good intentions, but it misses the bigger picture.
From a building perspective, the real issues usually come from:
- Poor material selection
- Hidden offgassing
- Trapped moisture
- Lack of ventilation
These aren’t problems you fix with a supplement. They’re baked into the design from day one. And when you introduce heat, moisture, and enclosed spaces—like a sauna—those issues don’t just sit quietly in the background.
They get magnified.
Where Infrared Saunas Fit (And Why They Make Sense)
This is where infrared saunas stand out—not just as a wellness tool, but as a more predictable building environment.
Unlike traditional steam or high-humidity saunas, infrared saunas:
- Operate at lower ambient temperatures
- Produce minimal moisture
- Heat the body directly rather than superheating the air
From a building science and low tox perspective, that combination matters.
Moisture & Mould Control: A Major Advantage
One of the biggest long-term issues I see in homes is moisture mismanagement. Traditional saunas introduce:
- High humidity
- Condensation
- A constant moisture load in the surrounding areas
Unless they’re detailed with dehumidifying devices nearby—like commercial wet areas often are—that creates ideal conditions for:
- Mould and odours
- Material degradation
- Hidden longterm damage
Most homes simply aren’t built to handle that.
Infrared saunas, on the other hand, are:
- Dry heat environments
- Easier to ventilate
- Far lower risk from a moisture standpoint
From a designer’s perspective, that makes them significantly easier to integrate into a home without creating new problems.
Materials Still Matter (A Lot)
Infrared or not, heat amplifies whatever materials you put inside the space. You still need to consider:
- Timber species
- Adhesives and glues
- Sealants and finishes
- Electrical components
A sauna built with questionable materials will still offgas when heated. This is the gap I see across the wellness market: plenty of “healthy” products, not enough transparency about what they’re actually made from.
Why My Wife and I Chose an Infrared Sauna
When we investigated adding a sauna to our own environment, I approached it the same way I approach any project:
- What are the materials?
- How does it behave under heat?
- What risks am I introducing into the home?
Infrared made sense immediately from a moisture control standpoint. From there, it came down to build quality.
Without turning this into a sales pitch, what stood out to me with Sun Stream Saunas was:
- Clear attention to material selection
- A genuine low tox construction focus
- A system that aligns with building science principles, not just wellness marketing
That alignment is rare.
Practical Tips: What to Look for in a Low Tox Sauna
1. Material Transparency
Look for minimal synthetic glues and finishes. If a manufacturer can’t tell you what’s in it, that’s a problem.
2. Moisture Management
Dry heat is easier to control. Avoid unnecessary humidity in enclosed spaces.
3. Ventilation
Yes, airflow matters, even with infrared. Don’t box it into a corner without considering the surrounding environment. Leave the sauna door open after use for some time to dry any fallen sweat.
4. Placement in the Home
Good placement reduces long-term risk. Think about:
- Garage vs internal room
- Proximity to bedrooms
- How air moves through the home
- Electrical requirements, such as nearby 13-amp power points, if necessary.
5. Build Quality Over Features
More tech doesn’t equal better. Focus on:
- Construction quality
- Material integrity
- Low EMF output
- Long-term performance
Final Thoughts
A healthy home isn’t created by adding random wellness features at the end. It’s the result of intentional design—materials, systems, and how each element interacts with the environment.
Well-built Infrared saunas fit into that system naturally.
Not because they’re trendy, but because they offer:
- More control
- Lower moisture risk
- Cleaner integration into the built environment
From a building designer’s perspective, that matters far more than hype. If you’re thinking about your home from a health perspective, start with the environment itself.
Everything else becomes easier from there.
