Sauna Accessories
Your walls are up, the heater is wired, and a short list still stands between you and the first löyly. That list is this page, and it splits two ways.
Some of it goes in before the boards close. Two vent openings, a fixed grille bringing fresh air in and an adjustable hatch to control what leaves, which PROSAUNAS notes is also what keeps a heater performing as intended and meeting its warranty requirements. Foil radiant barrier behind the cladding, 320 square feet to a roll, reflecting up to 97 percent of the radiant heat back at you instead of into your framing. Lighting built for the one corner you want it in: the PROSAUNAS strip hides behind a backrest or under a bench, sealed to IP67 and rated to 200°F, where ordinary LED tape gives up fast. Paraffin oil on the benches and backrests, which Harvia recommends to cut how much moisture and dirt the wood takes on.
The rest you pick up and use. A bucket and ladle. A thermometer and hygrometer, so the room tells you it is ready instead of you guessing. A hat that keeps the heat off your scalp so you can sit a round longer. Whisks, brushes, towels and robes, headrests and seat covers, soapstone, and a few things that are just fun.
Two things worth knowing before you order. Buy the vents, the foil and the low-voltage light run with your wood rather than after it, because all three live behind boards you are about to close up. And sauna stones and heater-specific parts sell with a heater so we can match size and count to your model, so look for those in heater accessories.
Both Bens run saunas at home and fly out to build them with customers around the country, which is how this list got picked.
Bench boards, cladding, trim and doors are in sauna materials. If you are not sure a vent or a light fits your heater, call or text (844) 565-1113 with the model and we will check it with you.

$32.00A coal black sauna pillow in Rento’s jacquard-woven Pino cotton, about 20 x 9 x 5 in, for head and neck support on the bench. Rento fills it with fast-drying polyester wadding and says it holds its shape wash after wash. Rinse it in the shower after a session, or machine wash it at 104°F. It matches the Pino seat covers.

$43.00A bench-length seat cover in jacquard-woven cotton, 59 x 20 in, in Rento’s coal black Pino pattern. Rento says light cotton suits the sauna: it feels cool against the skin, absorbs moisture and dries quickly, and the jacquard weave holds its shape and pattern wash after wash. It is the long version of the 20 x 24 in single Pino cover. Designed in Finland by Rento and made in Turkey.
Rento Kenno Sauna Seat Cover | Single 20 x 24 in or Bench Length 24 x 63 in, 7 Colors
Price range: $14.00 through $28.00Most people sit on a towel. This is the same idea, cut to the bench.

Finnmark FD-4 Sauna Cushion | Marine-Grade Vinyl Bench Cushion for the FD-4 Trinity
$269.00Order by room, not by seat count. The FD-4 cushion is made for the FD-4 Trinity, and like both Trinity cushions it is 17 in deep, 3 in shallower than the cushions for Finnmark’s FD-1 to FD-3 infrared rooms. It measures 44 in long and 2.5 in thick: black marine-grade vinyl, rated fade- and tear-resistant, over a non-toxic foam insert, with a full zipper for easier cleaning. Care steps from Finnmark’s manual are below. Covered by Finnmark’s 5-year limited residential warranty.
Finnmark FD-3 Sauna Cushion | Marine-Grade Vinyl Bench Cushion for the FD-3
$298.00Three or four people on the FD-3 means a long bench to pad. This cushion is 65.5 in long and 20 in deep, with 2.5 in of non-toxic foam inside a black marine-grade vinyl cover that Finnmark rates fade- and tear-resistant. A full zipper makes cleaning easier, and the everyday routine is short: towel on top, damp cloth after, no sprays. The steps below come from Finnmark’s own manual, and Finnmark’s 5-year limited warranty covers it in a home sauna.
Finnmark FD-2 Sauna Cushion | Marine-Grade Vinyl Bench Cushion for the FD-2
$269.00Two seats. One cushion. Finnmark cuts this one for the FD-2 bench, 41 in long, 20 in deep and 2.5 in thick, in black marine-grade vinyl over a non-toxic foam insert. The vinyl is rated fade- and tear-resistant, and the full zipper is there, in Finnmark’s words, “for easy cleaning.” A towel on top catches the sweat, so it stays off the vinyl and off the bench wood underneath. Care steps from Finnmark’s own manual are below, along with the 5-year limited residential warranty.
Finnmark FD-1 Sauna Cushion | Marine-Grade Vinyl Bench Cushion for the FD-1
$239.00How long can you sit on a bare wooden bench before you start shifting around? The Finnmark FD-1 cushion is cut for the one-person FD-1 bench: 30 in long, 20 in deep and 2.5 in thick. Black marine-grade vinyl, which Finnmark rates fade- and tear-resistant, wraps a non-toxic foam insert, and a full zipper makes cleaning easier. Keep a towel on it, wipe it with a damp cloth, skip the sprays. The full care steps from Finnmark’s manual are below, with Finnmark’s 5-year limited residential warranty.
Finnmark FD-5 Sauna Cushion | Marine-Grade Vinyl Bench Cushion for the FD-5 Trinity XL
$298.00The FD-5 Trinity XL runs full-spectrum infrared and a Finnish heater in one room, and this is the cushion Finnmark makes for it: 68 in long, 17 in deep and 2.5 in thick, black marine-grade vinyl over a non-toxic foam insert. Finnmark rates the vinyl fade- and tear-resistant and adds a full zipper for easier cleaning. It is not interchangeable with the FD-3 cushion, which is shorter and 3 in deeper. Towel on top, damp cloth after, no sprays. The full steps from Finnmark’s manual are below.
Saunapallo Sauna Ball | Hanging Steam Ball, Designed in Finland
Price range: $100.00 through $126.00Twelve minutes of steam from one fill. The Saunapallo is a stainless steel ball that hangs above your stove and lets water down through small holes in its base, so the stones get a steady drip instead of one hard splash. Nudge it with your ladle and it swings, spreading the water across the rock bed while you stay on the bench. Fill it before you climb in and the room is already humid when you sit down. Designed in Finland, finished in matte black, brushed steel or shiny steel. We think every sauna could use one.
SaunaLife Rounded Sauna Stones | 33 lb Box | Only Sold With Heater
$58.50The flame makes heat. The stones make it sauna. Each box contains 33 lb of rounded 1 to 2 in olivine diabase selected for heat storage and soft steam. SaunaLife specifies two boxes for TITAN SL1 even though the heater’s installed stone capacity is 44 lb; the purchase quantity and loaded capacity are different numbers. We keep both numbers visible so the complete heater package is clear before checkout. Inspect, rinse, and stack stones exactly as the heater manual directs.
SaunaLife SaunaTrekker Tent Connector
$28.50Two standard SaunaTrekkers, one zipped passage. SaunaLife’s insulated Tent Connector joins the door openings of two standard-size tents so you can create a second room for changing, cooling, or gathering beside the hot room. Its layered polyester construction follows the tents instead of leaving an exposed gap between them. The limitation matters: this connector fits the standard SaunaTrekker only and does not fit SaunaTrekker XL. We would rather repeat that than send you the wrong part.
SaunaLife SaunaTrekker Bench | Folding Cedar
$373.50A portable sauna still deserves two bench levels. SaunaLife’s folding cedar SaunaTrekker Bench puts a 60 in upper seat in the warmer part of the room and adds a 47 in lower step for feet, entry, or cooler seating. Both sections fold flat for the car and open without turning the tent into a furniture project. We chose the matched bench because its footprint leaves TITAN’s heater corner and exit path legible in both SaunaTrekker sizes.
SaunaLife TITAN SL1 Heater Guard | European Alder
$89.00TITAN already includes one of these. Add a second or third only when you want more of the heater wrapped in warm European alder. The curved SaunaLife TITAN SL1 Heater Guard clips to the stone basket and helps reduce accidental contact with the hot metal cage. We separated it as an add-on so the included guard never becomes a surprise double purchase. It does not change any required heater clearance and fits TITAN SL1 only.
SaunaLife TITAN SL1 Water Tank
$389.00Steam in the room and hot rinse water from the same heater. The stainless TITAN SL1 Water Tank uses heat from the burner, releases steady steam through openings in its top, and serves heated water through an integrated spigot. It is useful at a cabin or campsite where hot water would otherwise need another setup. The tank fits TITAN SL1 only. Heater, propane cylinder, and stones are sold separately.
SaunaLife TITAN SL1 Heat Shield
$189.00Two inches can decide whether a cabin layout works. This stainless Heat Shield clips onto TITAN SL1 and reduces the required cabin side and rear clearance from 6 to 4 in. Front clearance stays 16 in and overhead clearance stays 50 in. The shield must remain at least 1 in from combustible surfaces. We are repeating the limitation because it matters: the Heat Shield does not reduce TITAN clearances inside either SaunaTrekker tent.
Cozy Heat COZY FIRE Outdoor Fire Pit
$1,570.50Bring Cozy’s stone-cage look out to the fire circle. COZY FIRE places a natural wood flame inside a double iron mesh wall designed to hold about 55 lb of decorative stone. The cage screens some direct radiant heat and turns the fire into a 30 in wide, 26 in high centerpiece instead of a bare steel bowl. Stones are separate. Use it outdoors on a stable noncombustible surface and follow local fire rules.
Cozy Heat Chimney Cover Quattro H500
$715.50Keep the Quattro square all the way up. The compact Quattro cover carries its horizontal bars and crisp footprint around the exposed flue. At 19.7 in high, the Cozy Heat Chimney Cover Quattro H500 adds room for about 66 lb of stone and fits Quattro, 12 or 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
Cozy Heat Chimney Cover SW H700
$787.50Finish the tallest SW with a taller cover. This 18 kW cover continues the SW stone-column effect where a longer chimney section stays in view. At 27.6 in high, the Cozy Heat Chimney Cover SW H700 adds room for about 82 lb of stone and fits SW 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
Cozy Heat Chimney Cover SW H500
$715.50Keep the SW wave moving upward. The compact SW cover echoes the heater's vertical wave pattern around the lower exposed chimney. At 19.7 in high, the Cozy Heat Chimney Cover SW H500 adds room for about 44 lb of stone and fits SW, 12 or 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
Cozy Heat Chimney Cover OG H700
$787.50Let the larger OG finish at full height. This taller cover carries the flared OG profile farther up the exposed chimney on 18 kW installations. At 27.6 in high, the Cozy Heat Chimney Cover OG H700 adds room for about 132 lb of stone and fits OG 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
Cozy Heat Chimney Cover OG H500
$715.50Continue the OG's flare above the heater. The compact OG cover repeats the sculpted cage language instead of placing a bare round pipe over it. At 19.7 in high, the Cozy Heat Chimney Cover OG H500 adds room for about 88 lb of stone and fits OG, 12 or 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
Cozy Heat Chimney Cover Grid H680
$594.00Give an 18 kW round-cage stove a taller chimney finish. This taller Grid cover extends the open mesh profile when more of the chimney remains visible. At 26.8 in high, the Cozy Heat Chimney Cover Grid H680 adds room for about 132 lb of stone and fits Standard and O, 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
Cozy Heat Chimney Cover Grid H500
$549.00Carry the open round cage above the stove. The compact Grid cover keeps the Standard or O silhouette moving up the first exposed chimney section. At 19.7 in high, the Cozy Heat Chimney Cover Grid H500 adds room for about 88 lb of stone and fits Standard and O, 12 or 18 kW (including TW), not every Cozy model. Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.
PROSAUNAS Round Thermo-Abachi Sauna Ventilation Cover
Price range: $111.20 through $119.20The sauna rabbit hole is real, but this choice is simple: you need intake and exhaust vents. This round PROSAUNAS cover finishes a standard 3.9-inch sauna ventilation duct while its rotating face lets you adjust airflow. Choose natural sanded thermo-abachi or brushed black; both pair well with any sauna wood, blending in or adding intentional contrast. The solid 5.9-inch face is made in Estonia from PEFC-certified wood and moisture-resistant materials and includes a 2-year limited warranty for consumer use.
ProSaunas Oiled Birch Sauna Ladle | 14.5 in, Made in Estonia
$27.20A ladle is the one tool in a sauna that everybody touches. This one is oiled birch, 14.5 inches from end to end, with a long handle that keeps your knuckles out of the rising steam and a wide, shallow bowl that lays water across the stones instead of punching a hole in the middle of them. Made in Estonia by the same people who mill our thermally modified cladding. Oiling is what separates the two versions we carry. The oil closes the grain a little further, so the ladle sheds water faster and keeps its colour longer against the constant wet and dry cycle of a sauna. It is the sort of thing you buy once and stop thinking about.
ProSaunas Birch Sauna Ladle | 14.5 in, Made in Estonia
$25.50A ladle is the one tool in a sauna that everybody touches. This one is birch, 14.5 inches from end to end, with a long handle that keeps your knuckles out of the rising steam and a wide, shallow bowl that lays water across the stones instead of punching a hole in the middle of them. Made in Estonia by the same people who mill our thermally modified cladding. This is the plain birch version, left natural. It will grey slightly with years of use, the way untreated birch does, which some people prefer and some do not. It is the sort of thing you buy once and stop thinking about.
SaunaLife Essentials Set 3 | Bucket, Ladle, Thermometer, Hygrometer
$198.00Four things every traditional sauna needs, bought once instead of four times. A 1 gallon spruce bucket with a plastic tub inside it so the wood never has to be watertight, a hand-carved birch ladle with a leather loop so it hangs up to dry, and a matched black thermometer and hygrometer for the wall. If you are finishing a room and do not want to spend an evening comparing buckets, this is the shortcut.
SaunaLife X7 Sauna Floor | European Aspen, Pre-Assembled
$295.00Standing barefoot on a cold slab is the fastest way to undo a hot room. The X7 floor is SaunaLife’s aspen decking for their Model X7 indoor sauna: pre-assembled, 31.4 inches by 28.3 inches, sitting 5.5 inches up so air and water pass underneath instead of pooling under your feet. Aspen is the traditional choice for anything skin touches in a sauna because it stays cool to the touch when everything around it is not.
SaunaLife X6 Sauna Floor | European Aspen, Pre-Assembled
$425.00Standing barefoot on a cold slab is the fastest way to undo a hot room. The X6 floor is SaunaLife’s aspen decking for their Model X6 indoor sauna: pre-assembled, 24.4 inches by 22.4 inches, sitting 5.5 inches up so air and water pass underneath instead of pooling under your feet. Aspen is the traditional choice for anything skin touches in a sauna because it stays cool to the touch when everything around it is not.
HUUM HIVE Air Tunnel | Stainless Steel, Faster Heat-Up
$331.00Check the date on your heater before you buy this one. Every HIVE built since April 2024 already has an Air Tunnel inside it. If yours is older, this is the stainless steel insert that sits down among the stones and gives the heat a channel to climb through: HUUM rates it at a 25 percent shorter heat-up, longer element life, and fewer stones needed to fill the basket. It fits every HIVE and HIVE Mini electric model. A small part that changes how long you wait to get in.
Saunum Grapefruit Aroma Oil Set | Bottle, Dropper and Ceramic Bowl
$58.00Most people pour scent straight into the bucket, and most people overdo it on the first try. This set is built to stop that. A 0.34 fl oz bottle of grapefruit oil, a dropper so you can count what goes in, and a ceramic bowl that sits in the room and lets the oil come off slowly instead of all at once in a single blast of steam. Grapefruit is the bright, citrus end of the sauna scent range, not the pine and birch end. Made for Saunum Air heaters and the AirSolo.
Saunum AutoLeil Pre-Bent Pipe | Required Primary Pipe
$173.00Read this before you order an AutoLeil: the pipe is not in the box. The Saunum automatic water dispensing system needs this pre-bent primary pipe to run, and it is a separate line on the order. Coming pre-bent is the point. It arrives in the shape it needs to be in, which takes the fabrication step out of the install and lets it fit a range of room layouts without anyone cutting and forming steel on site.
