As an integrative medicine physician, I think of a sauna session as a prescription — and like any prescription, the details matter. The right accessories don’t just make your sauna more comfortable; they help you control the dose of heat you’re applying, monitor your environment, and get the maximum therapeutic benefit from every session. Over the years I’ve tested dozens of products in my own home sauna, and in this guide I’m sharing my top picks for the best sauna accessories across every category.
Whether you’re outfitting a brand-new sauna or upgrading an older one, this list covers everything you need — and nothing you don’t.
1. Sauna Thermometer and Hygrometer
The single most important piece of information in a sauna session is temperature. Without a reliable thermometer, you’re guessing — and in a therapeutic context, guessing is how people overstay their time at dangerous heat levels or, conversely, never get the cardiovascular benefits that require reaching 150°F or above.
I recommend a combination thermometer/hygrometer so you can track humidity alongside temperature. Finnish sauna tradition calls for a specific relationship between the two: a drier 190°F feels very different from a steamy 170°F, and both have their place depending on your goals.
What to look for:
- Dual temperature/humidity display
- Wood housing (metal gets dangerously hot)
- Reads up to at least 220°F / 105°C
- Wall-mountable at bench height where you’ll actually be sitting
My top pick: The Saunum or Finnlo sauna thermo-hygrometer — solid wood build, accurate to ±2°F, and reads the full range you need. A reliable wood-cased combo unit runs $20–$40 on Amazon and is worth every cent.
2. Sauna Ladle and Bucket Set
If you’re using a traditional Finnish sauna with a wood or electric heater and actual sauna stones, a ladle and bucket are non-negotiable. This is how you create löyly — the steam burst that defines the Finnish sauna experience and is responsible for many of its detoxification and respiratory benefits.
The ritual matters here. Slowly pouring water over hot stones with a long-handled ladle gives you precise control over steam intensity. It’s meditative, and it’s the correct technique. A cheap plastic ladle or repurposed kitchen bowl simply doesn’t cut it.
What to look for:
- Natural wood construction (pine, alder, or aspen) — no metal handles that burn hands
- Bucket capacity of at least 3 liters
- Ladle with a 16–20 inch handle for safe distance from the heater
- Matching set for aesthetics (you’ll be staring at it for years)
My top pick: Look for a Finnish-style wooden sauna bucket and ladle set in pine or alder. These run $30–$60 and last indefinitely with basic care (rinse after use, let dry completely).
3. Sauna Stones
Not all rocks are created equal — and using the wrong stones in your sauna heater can be genuinely dangerous. Certain rock types can crack and explode when rapidly heated and cooled with water. Proper sauna stones are specifically selected for their heat retention and thermal shock resistance.
I replace the stones in my sauna every two to three years. Fresh stones produce denser, smoother steam and make the entire session feel more authentic.
What to look for:
- Olivine diabase or peridotite (traditional Finnish stones)
- Smooth, rounded, fist-sized pieces — no sharp edges that reduce airflow
- Dense, heavy stones that retain heat longer
- No cracks or seams that could cause fracture
My top pick: Olivine diabase sauna stones, sold in 22–44 lb bags. Enough to fill most residential heaters runs $25–$50. Harvia and Sawo both make excellent options widely available on Amazon.
4. Sauna Headrest and Backrest
This is the category most people overlook, and it’s the one I most consistently recommend to patients who tell me they can’t stay in the sauna long enough to get real benefits. The answer is usually discomfort — not heat intolerance. A good headrest and backrest let you fully relax your muscles, which deepens the therapeutic effect and extends how long you can comfortably stay in.
Wood benches are beautiful but hard. After 10–15 minutes, tension in the neck and lower back becomes a limiting factor. A contoured wood headrest or a cushioned backrest solves this completely.
What to look for:
- Aspen or pine construction (both heat-safe and splinter-resistant)
- Ergonomic contour that fits natural cervical and lumbar curves
- Open slat construction for airflow (solid pieces trap moisture and breed mildew)
- Easy to remove and dry between sessions
My top pick: A contoured pine or aspen sauna headrest paired with a slatted wood backrest. Both are under $30 individually and dramatically change the experience.
5. Sauna Towels
You need two types of towels in a sauna: one to sit on (to absorb sweat and protect the bench) and one to cool down with. The wrong towel — thin, synthetic, or too small — leaves you uncomfortable and defeats the purpose of the session.
I’ve tried linen, microfiber, and every cotton weight on the market. For sauna use specifically, the material and size matter more than the brand.
What to look for:
- 100% Turkish or Egyptian cotton — nothing synthetic
- At least 35×70 inches (you need to fully recline on it)
- Medium weight (300–500 GSM) — heavier towels take too long to dry in a humid environment
- Light colors — dark dyes can release in high heat and humidity
My top pick: Oversized Turkish cotton towels in natural or white. A set of four runs $40–$60 and holds up beautifully to the repeated high-heat washing that sauna use demands.
6. Sauna Essential Oils
This is where sessions go from functional to transcendent. Adding a few drops of the right essential oil to your löyly water transforms the steam and engages the respiratory system in ways that extend far beyond simple relaxation. Eucalyptus opens airways; birch is the traditional Finnish choice; peppermint creates a cooling sensation that feels paradoxical and wonderful at 180°F.
From a clinical standpoint, inhaling eucalyptus steam has genuine evidence behind it for reducing upper respiratory inflammation and supporting mucociliary clearance. I recommend it to patients with seasonal congestion as a complement to other treatments.
What to look for:
- 100% pure essential oils — no synthetic fragrance, no carrier oils pre-added
- Specifically marketed as sauna-safe
- Start with eucalyptus, pine, or birch tar — these are traditional and well-tolerated
- Always dilute: 5–10 drops per liter of water maximum
My top pick: Pure eucalyptus essential oil from a reputable brand like Edens Garden or Plant Therapy. A 4-oz bottle lasts months of regular use and costs $10–$20.
7. Sand Timer and Sauna Lighting
Two final accessories that round out a complete sauna setup:
Sand Timer: A sauna-specific sand timer eliminates the temptation to check your phone (which you shouldn’t bring in) and provides a tactile, meditative way to track your rounds. Traditional Finnish sauna etiquette involves rounds of 10–20 minutes with cooling breaks in between. A 15-minute sand timer keeps this rhythm without screens.
Look for a wood-framed sand timer rated for high-heat environments — standard glass timers can crack in a 190°F sauna. These run $15–$25.
Sauna Lighting: Harsh overhead lighting kills the mood and defeats the parasympathetic activation that makes sauna beneficial for stress and sleep. I strongly recommend replacing or supplementing standard lighting with low-voltage sauna LED lights in warm amber tones. They’re inexpensive ($20–$50), heat-safe, and transform the atmosphere completely.
Building Your Complete Sauna Accessory Kit
Here’s how I think about building a kit from scratch, organized by priority:
Start here (essential):
- Thermometer/hygrometer — know your environment
- Ladle and bucket — if you have a traditional heater
- Quality towels — sit on something absorbent
Add next (high value):
- Headrest and backrest — extend your session length
- Fresh sauna stones — if yours are more than 3 years old
- Essential oils — eucalyptus to start
Complete the experience:
- Sand timer — analog session tracking
- Ambient LED lighting — parasympathetic activation
The total cost for a complete setup runs roughly $150–$250 if you buy quality versions of everything. Given that a single infrared sauna session at a spa costs $40–$80, the accessories pay for themselves within a few months of home use.
My final advice: resist the urge to buy cheap versions of the things you’ll touch and use every single session — the ladle, the towels, the headrest. These are where quality makes a daily difference. For the stones and thermometer, mid-range options perform as well as premium ones.
Outfit your sauna thoughtfully, and it becomes not just a room in your house but a genuine wellness tool — one you’ll use more often and get more from because the details are right.
