Buying the sauna is the big decision. What happens after delivery is a string of small ones: where do you check the temperature, what do you pour water with, how do you keep track of time without bringing a phone into 180-degree heat, and why does the backrest bench feel so hard after ten minutes? These are the questions that turn a new home sauna from an expensive box into a routine you actually use.
This guide covers the accessories that solve those specific problems. We compared listings on Amazon based on materials, published specifications, capacity, and owner reviews, and we kept it to gear with a clear job. Nothing here is required to use a sauna. All of it makes the experience easier to repeat.
One distinction matters before you shop: a bucket, ladle, and sauna stones only apply to traditional saunas with a rock-topped heater (electric or wood-burning). If you own an infrared cabin, skip those and focus on the thermometer, timer, hat, and backrest. Never pour water inside an infrared sauna.

1. A thermometer and hygrometer you can read from the bench
Most sauna controllers show a set temperature, and many show a reading from a sensor mounted near the heater or the ceiling. Neither tells you what the air feels like where you sit. Heat stratifies sharply in a sauna, so the upper bench can run much hotter than the lower one. A wall gauge at head height when seated gives you a reading that matches your experience, and the hygrometer half shows how much a ladle of water actually changes the humidity.
Best Value: defull Stainless Steel Sauna Thermometer Hygrometer
A 5-inch dial with a 403 stainless steel case, aluminum alloy dial face, and heat-resistant glass. The temperature scale runs 70 to 250°F with a red zone marked from 150 to 212°F, and the humidity scale covers 0 to 100% RH. The listing notes a slim 21 mm profile and a 6-month warranty. At around $14 at the time of writing (October 2026), it is an easy add-on for any sauna type, including infrared.
Best Looking: Northwood Sauna 2-in-1 Thermometer and Hygrometer (Red Cedar)
Two gold-tone dials set in a handmade Canadian red cedar mount. The thermometer reads Fahrenheit on the outer ring and Celsius on the inner ring. Northwood says both instruments are calibrated during assembly and includes recalibration instructions, which is a useful detail since analog gauges can drift over years of heat cycling. It costs more than a plain steel gauge, and the extra money goes to the wood and finish that match a cedar interior. A Finnish pine version is also sold if your sauna is lighter wood.
Placement tip: mount the gauge on a side wall roughly at seated head height, not directly above the heater, and follow any placement guidance in your heater or cabin manual. If your controller and wall gauge disagree by 20 degrees or more, that is normal stratification, not necessarily a broken sensor.
2. A bucket and ladle (traditional saunas only)
Pouring water over hot stones, called löyly in Finnish, is the main way to adjust how a traditional sauna feels. A short burst of steam makes the room feel noticeably hotter without changing the thermostat. A proper ladle with a long handle keeps your hand away from the steam plume, and a bucket keeps water within reach so you are not getting up between pours.
Before you buy, confirm your heater is rated for water. Most traditional electric and wood heaters are, but check the manual. Use plain tap water unless your heater maker approves anything else, and add only small amounts at a time.
Premium Pick: Northwood Sauna Red Cedar Bucket and Ladle Set
Handmade from knotless Canadian red cedar with a thick natural rope handle. The bucket holds 1 gallon (4 L) and the ladle holds 3.4 oz (100 mL), which Northwood describes as the right pour size for most heaters. A removable liner made from recycled plastic sits inside the bucket, so the wood is not constantly soaked and the liner can be cleaned separately. This is the most expensive item in this guide at roughly $90 at the time of writing (October 2026), and it suits buyers who want accessories that match a wood interior.
Larger Capacity: LIFTATAPA 7 L Aluminum Bucket and Ladle
An aluminum bucket with a 7 L (1.85 gallon) capacity, 9.45 inches across and 7.87 inches tall, plus a long wooden-handled ladle. Aluminum does not need the drying routine that wood does, and the larger volume means fewer refills during a long session or when two or three people share the sauna. It is sold in black, which suits more modern sauna builds.
Wood or aluminum?
Wood looks traditional, stays cooler to the touch, and matches cedar or spruce benches. It needs to dry fully between sessions, which is why a liner helps. Aluminum is lower maintenance and usually cheaper per liter of capacity, but the bucket itself can get warm if you leave it close to the heater. Either works. Pick the one that fits how often you will clean it.
3. A sand timer that lives on the wall
Phones and smartwatches are not designed for sustained sauna heat, and many manufacturers warn against it. A sand timer is the low-tech answer. It does not need batteries, it does not overheat, and flipping it becomes part of the ritual.
Our Pick: Northwood Sauna 15-Minute Sand Timer
A wall-mounted, rotating 15-minute hourglass in a red cedar housing with markings engraved into the wood rather than printed on. The enclosed design means you rotate the whole glass in its frame instead of picking it up. Fifteen minutes is a common length for a single round, and you can flip it again if you want a longer one.
4. A wool sauna hat
Sauna hats look odd to first-timers, but they are standard in Finland and Russia. The idea is simple: heat rises, your head sits in the hottest air in the room, and a loose wool felt hat acts as a buffer. Many users say it lets them stay comfortable on the upper bench a bit longer. It also helps keep very hot air off dyed or color-treated hair.
Our Pick: Halsa 100% Natural Wool Felt Sauna Hat
A handmade bucket-style hat in 100% wool felt with no synthetic blend, sized one-size-fits-most. Halsa lists it for traditional, steam, and infrared saunas and suggests soaking it in cool water before a session for some evaporative cooling, which is a traditional banya habit. Under $20 at the time of writing (October 2026), it is one of the cheapest upgrades on this list.
Synthetic hats can hold heat and feel clammy. Wool or a wool-linen blend is the material to look for, and hand washing in cool water helps it keep its shape.
5. A backrest for long sessions
Sauna benches are usually flat, and many cabins put you against a vertical wall. After ten minutes, that gets uncomfortable, especially on the upper bench where the wall is also hot. A slatted backrest gives you a supportive angle and keeps your back off the hottest surface.
Our Pick: RUVARO Canadian Red Cedar Sauna Backrest
An S-curve backrest made from red cedar with open slats for airflow and anti-slip pads on the base. It arrives assembled, and RUVARO describes reinforced joints so it stays solid with frequent use. The listing says it works in both infrared and traditional saunas and doubles as a headrest when you lie down on a longer bench.
Measure your bench depth before ordering. A backrest takes several inches of seat depth, which can be tight on a narrow barrel sauna bench.
6. Replacement sauna stones (traditional heaters)
Sauna stones slowly break down from repeated heating and water. Crumbled stones and grit can pack together and reduce airflow through the heater. Heater makers commonly recommend checking the stones periodically, rearranging them, and replacing any that have cracked or crumbled. Your manual will say how often, what size, and how many pounds your model needs.
Our Pick: SAUNOM Vulcanite Sauna Stones, 33 lb
A 33 lb box of natural vulcanite stones, rounded and sized between 2 and 3.5 inches. SAUNOM lists them for both electric and wood-burning heaters, says they are selected for thermal shock resistance, and ships them pre-sized and clean. The listing recommends rinsing before use and stacking smaller stones at the bottom with larger ones on top so air can move through the heater.
Important: some heater makers specify their own stones or a particular size range, and using something different can affect warranty coverage. Check the manual before swapping brands. Always do stone work with the heater off, cooled, and disconnected from power.
What to skip
- Glass-bulb mercury thermometers. Stick with dial or digital gauges rated for sauna temperatures.
- Bluetooth speakers not rated for heat. Most consumer electronics list maximum operating temperatures well below sauna air. Keep them outside the room.
- Essential oils poured directly on stones. Undiluted oil can flash or smoke on hot rocks. If you want scent, use a product made for sauna water and follow its dilution directions.
A quick word on safety
Accessories make sauna use more comfortable, but they do not change the basics. Drink water, keep rounds within what feels comfortable, skip alcohol before and during sessions, and leave if you feel dizzy or unwell. If you are pregnant, have a heart condition or blood pressure concerns, or take medications that affect heat tolerance, talk with your doctor before using a sauna.

FAQ
Q: What sauna accessories do I actually need first?
A thermometer you can read from the bench and a timer. For a traditional sauna, add a bucket and ladle. A hat and backrest are comfort upgrades you can add later.
Q: Can I use a bucket and ladle in an infrared sauna?
No. Infrared heaters are not designed for water, and splashing them can damage the panels or create an electrical hazard. Buckets and ladles are for rock-topped traditional heaters only.
Q: Why does my wall thermometer read lower than the sauna controller?
Controllers often read from a sensor near the ceiling or heater, where the air is hottest. A gauge at seated head height usually reads lower. Both can be accurate for their location.
Q: How often should sauna stones be replaced?
It depends on use and the heater. Many manufacturers suggest inspecting and rearranging stones regularly and replacing cracked or crumbling ones. Your heater manual has the specific guidance for your model.
Q: Do sauna hats really make a difference?
They are a comfort item. Many regular users like how a wool hat keeps the hottest air off the head and hair, especially on the upper bench. They are inexpensive enough to try.
Q: Is cedar better than other woods for accessories?
Cedar is popular because it handles moisture well and has a pleasant scent. Pine and aspen accessories also work. The main thing is letting any wood item dry fully between sessions.
