Full Spectrum Light. Incandescent Warmth.
Float Toronto is excited to introduce our first new offering in the twelve years of service: the FireLight Sauna: red, near and mid-to-far infrared light therapy in a custom-built cedar sauna.
The healing energy of the radiant heat and light will make a great complement to the contemplative darkness of the tank.
Opens December 8. Book your session.
Fire and WaterUnder one Roof
Infrared Light & Thermal Heat
Light and radiant warmth reach deep into the body. Guests report feeling warmed through, loose and energised.
- Energy in – 30 min at 55–65°C
- Stimulating, sympathetic-to-parasympathetic
- Enjoy before or after a float, or on its own!
Sensory Deprivation Floating
Light, sound, gravity and temperature removed. The body stops managing input and the nervous system drops into rest.
- Stimulus out – 60 min, skin-temp water
- Quieting, theta-state stillness
- Our original service since 2014
Zero Flicker
FireLight bulbs are incandescent: a steady light with no flicker and no strobing.
Faraday EMF Shielding
Stainless steel faraday cages prevent any EMF leakage from the lights, allowing your system to relax even deeper into the experience.
Radiant Core Heating
Heat delivered into tissue rather than into air – a deeper core response at a temperature you can breathe in.
Light and Heat Together
Red and near infrared light arrive with deep, comfortable heat in one session.
Deep Core Sweat
A full thermal load at a lower air temperature, sustained long enough to matter.
Calm Afterglow
Guests report leaving relaxed and clear-headed, especially when they pair it with a float.
Joint & Muscle Relief
Guests report less stiffness in the areas that need recovery.

FireLight Sauna FAQ
FireLight Sauna FAQ
Most people sit 18 to 30 inches away. That sweet spot delivers deep warmth without overwhelming heat.
If you’re looking for gentle stimulation, start farther back. Want stronger activation? Move closer. Adjust based on comfort – the goal is to feel relaxed, open, and warmly held.
This depends on your goal. If you’re going for full-body coverage, gentle rotation helps ensure even exposure. But for targeted sessions -on your chest, face, or back – just stay still and soak it in. Let the light do the work.
Beyond even exposure, rotation creates thermal contrast: while one side heats, the other cools slightly. Many guests find that contrast invigorating.
Yes – intensely and efficiently. Our FireLight Sauna uses radiant red, near and mid-to-far infrared heat that warms you from the inside out. Unlike a traditional sauna, which heats the air around you, this heats you directly, so you’re not sitting in a box of stifling air, gasping for breath. It feels more like basking in the sun than sitting in a steam room.
The result? A steady, sustained sweat that feels clean, grounded, and deeply invigorating, without the lung-scorching heat.
No. Lying down makes it passive -it reduces circulation, collapses your posture, and limits your body’s ability to sweat and release. Sitting upright or standing is what makes it powerful. When you’re upright, you can rotate slowly for full-body exposure, enhanced lymphatic flow, and deeper light absorption. Your breath opens and your spine aligns.
Lying down may feel relaxing, but it misses the point. This is an active session, not nap time.
Think of it less like lounging and more like aligning. Upright. Present. Fully lit.
Nope. It’s completely silent.
There are no fans, no electronics, and no motors – just pure incandescent light, gently heating your body. You’ll have a perfectly quiet space to rest or meditate.
Yes. Plenty of guests use the sauna alongside a fast or a structured wellness protocol, and it sits comfortably within one.
Many guests find it a good companion to that kind of routine. Just make sure to hydrate well, support your electrolytes, and ease into it if your system is already under stress.
If you’re fasting or following a protocol under medical supervision, check with your practitioner first.
Yes, and it’s a big part of why we chose this sauna. It heats you directly rather than heating the air, so you’re less likely to feel lightheaded or overwhelmed, even if you’re sensitive to heat.
It also includes full EMF shielding, which makes the cabin a grounded, low-EMF space. Guests who are sensitive to their environment often find it noticeably calmer than a conventional sauna.
If you have a health condition or you’re unsure whether heat is right for you, check with your healthcare provider before your first session.
You can, but it’s not recommended. The more skin exposed, the more light and heat your body receives. Most people go nude, you can wear a provided towel, but avoid synthetic fabrics, which can block light or off-gas. Just keep it simple, breathable, and comfortable.
All saunas aim to raise your core body temperature, but how they do it makes all the difference.
A far-infrared (FIR) sauna uses only longer wavelengths (typically 3000+ nm), which are absorbed mostly by water and mainly heat the surface of your skin. On their own, those wavelengths make sessions slower and less efficient, and they don’t activate photobiomodulation, because our bodies don’t have light-sensitive receptors (chromophores) for them.
Our FireLight Sauna covers the whole range: red and near infrared (NIR, 700-1500 nm) incandescent light that penetrates deeper into tissue and raises your core temperature faster, plus mid-to-far infrared for surface warmth. It’s full-spectrum radiant heat – just like sunlight, but without the UV. Guests report a deeper, more even warmth than they get from a far-infrared-only sauna.
