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.

4Living Black Pine Sauna Bucket | 1.1 gal, Plastic Liner
$53.00Every all-wood sauna bucket eventually leaks. The staves dry, the joints open, and one day you carry it in and it drips a line across the floor. This one solves that the sensible way: a pine bucket in a black finish with a plastic liner inside it, so the wood is the part you look at and the plastic is the part that holds water. 1.1 gallons, 10.6 inches tall, made in Finland. It will outlive two of the pretty ones.
4Living Black Pine Sauna Ladle | 14.2 in, Made in Finland
$27.00The companion to the black bucket, and the reason to buy the two together: a mismatched ladle is the thing your eye lands on every time you reach for it. Pine in the same black finish, 14.2 inches long, with a shallow 3.9 inch bowl that spreads water across the stones rather than dropping it in one place. Made in Finland. Simple, and correct for a dark interior.
4Living Pine Sauna Sand Timer | 15 Minute, Made in Finland
$24.00Phones do not belong in a hot room. They also do not survive one. A sand timer is the old answer and it is still the right one: flip it, and fifteen minutes later you know without looking at anything with a screen. Pine frame, 11.4 inches tall, made in Finland. Fifteen minutes happens to be about the length of a good round, which is not a coincidence.
Auroom Aroma Set
$80.00The Auroom Aroma Set packs in five distinct essential oils. Each 0.5 fl oz bottle contains a different type of oil, including Eucalyptus, Juniper, Pine, Orange, and Lemon. These oils are meant to enhance the experience of sauna use or serve as an introduction to aromatherapy for beginners.

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.

Finnmark FD-4 Sauna Cover | Waterproof Outdoor Cover for the FD-4 Trinity Hybrid

HaLu Sauna Round Headrest Pillow in Clear Aspen
$72.95Widely known as the most comfortable sauna pillow in Finland, the Halu Headrest is now available in North America in beautiful clear Aspen.
With four flexible dishes the HaLu pillow does not only look totally different as the traditional head rests but it also feels really different.
You hardly notice that there is something situated beneath the head, but the head is lifted in such a way that it provides a comfortable position. You are not slipping off and the pressure from the head rather than from the shoulder prevents the pillow from moving. This way the neck muscles can completely relax.
The wooden Halu pillow is the ultimate headrest for usage in the sauna. More and more people know about the existence of the pillow and enjoy the comfort and ergonomics

$351.00The deep rail in Harvia’s Virta family: 22.6 in wide, 23.5 in deep, 3.9 in high, wood, CE and EAC certified. Harvia’s railing sheet lists the HL3L against the Virta Combi HL110S and HL110SA, and the 10.5 kW Virta Combi we sell is the HL110SA, an exact model-code match rather than a family guess. Ships as rail plus installation manual.
Harvia HL3M Safety Rail for Virta HL110, HL70SA and HL90SA | Wood
$341.00The middle rail in Harvia’s Virta family: 22.6 in wide, 20.6 in deep, 3.9 in high, wood, CE and EAC certified. Harvia’s railing sheet lists the HL3M against the Virta HL110, HL70S, HL70SA, HL90S and HL90SA, the 10.5 kW Virta and the steam-equipped Combi models, and it is specified ‘for use with Virta HL110/HL70SA/HL90SA’. Ships as rail plus installation manual.

$330.00The shallow rail in Harvia’s Virta family: 22.6 in wide, 17.8 in deep, 3.9 in high, in wood, CE and EAC certified. Harvia’s railing sheet lists the HL3S against the Virta HL70 and HL90, and it is specified ‘for use with Virta HL70/90’.

Harvia HPC2 Embedding Flange | Cilindro 6 and 8 kW, Stainless Steel
$210.00The flange is what turns a heater sitting on a bench into a heater built into one. Stainless steel, 19.7 inches across, made for the 6 and 8 kW Cilindro. It shields the surrounding timber from radiant heat, which is what lets the cut-out sit close to the heater body instead of standing off at a safe but ugly distance. The finished detail is a clean surface with a cylinder rising through it.
Harvia HPC3 Safety Railing | Cilindro 6 and 8 kW, Heat-Treated Birch
$274.00A Cilindro is a cylinder of hot steel standing at shin height in a small dark room, and the first time somebody stands up too fast next to one they find that out. The HPC3 is Harvia’s own guard for the 6 and 8 kW Cilindro: four heat-treated birch arches held off the heater on stainless steel mounts, 20.1 inches square. It keeps skin off the shell without hiding the heater, and the birch reads as part of the room rather than as safety equipment bolted on.
Harvia HPC7 Embedding Flange | Cilindro 10.5 kW, Stainless Steel
$204.00Dropping a Cilindro through the bench is the detail that makes a sauna look designed rather than assembled. The HPC7 is the stainless steel collar that makes it possible on the 10.5 kW model: it lines the cut-out, shields the surrounding timber from radiant heat, and lets the hole be only slightly larger than the heater itself, so the finished result reads as one continuous surface with a heater rising out of it.
Harvia HPCU4LUL LED Safety Railing | Cilindro 10.5 kW, Birch
$574.00This is the railing that doubles as the room’s light. Four heat-treated birch arches on stainless mounts, sized for the 10.5 kW Cilindro, with LEDs built into the frame that throw their light at the heater rather than at you. The steel shell bounces it back indirectly, so the heater glows softly from behind its own guard and you get safety and atmosphere out of one part. 14.2 inch diameter.
Harvia HSP1 Embedding Flange for Harvia Spirit | Stainless Steel
$131.00When a Harvia Spirit is recessed into a bench, the HSP1 is the stainless flange that finishes the opening. Harvia’s description is that it ‘ensures a neat finish and also acts as a thermal radiation shield for your benches’; Note that it protects the bench structures from water and heat and that the stainless steel is easy to keep clean. It measures 22.44 x 17.32 in, weighs 1.43 lb, and is designed, engineered and made in Finland.
Harvia HSP3M Safety Railing for Harvia Spirit | Heat-Treated Birch
$267.00A bar of black-painted heat-treated birch on stainless steel brackets that fastens directly to a Harvia Spirit. Harvia’s own line is that the birch surface is always safe to touch. It measures 21.5 x 17.7 x 5.1 in and weighs 4.4 lb. Specified for the Spirit SP60/90.
Harvia Paraffin Oil For Sauna
$31.00Harvia’s Paraffin Oil is a trusted treatment for interior sauna wood surfaces, most commonly used on benches. Paraffin oil helps reduce moisture and dirt absorption of any wood to enhance the lifespan and protect your investment.

Harvia recommends you protect the benches and other frequently contacted surfaces with paraffin oil 1-3 times a year.

Harvia SAA00101 Sauna Drip Tray | Steel, for Floor-Standing Heaters
$87.00Water misses the stones. It happens to everybody, usually around the third ladle, and it lands on the floor under the heater. The SAA00101 is Harvia’s steel catch tray for floor-standing heaters: 17.2 inches wide, 15.2 deep, and nine tenths of an inch tall, so it sits under the base instead of announcing itself. Steel, black, 3.1 pounds. It is the kind of part nobody adds to the first order and most people want by the second winter, so we would rather you saw it now.
Harvia SASL2M Autodose Design Pipe | Black, Wall-Integrated
$375.75The nicest sauna interiors hide their plumbing. This is the piece that lets an automatic water dosing system feed the stones without a length of tube running down your wall. A black steel pipe just under 24 inches long, fitted with a low-profile nozzle, mounted above the heater and fed through the wall panel from behind. The Autodose unit itself is a separate purchase. This is the part people forget to order, then wish they had, once the panels are up and the wall is closed.
Harvia SASPO240 Safety Railing for Legend 240 and 300 Wood Stoves
$668.00Heat-treated birch on stainless steel elements, installed directly onto the stove rather than standing on the floor. This is the larger of Harvia’s two full-ring Legend railings, 33.5 in outer diameter with a 23.6 in inner opening, and it covers the Legend PO165, 240, 240 SL, 240 Duo, 300 and 300 Duo. 33.46 in across, 11 lb.
Harvia WL110 Protective Bedding for Wood Sauna Stoves | 22 x 25 in
$356.00An aluminum-zinc-coated steel plate with adjustable feet that goes under a wood-burning sauna stove. Harvia’s instruction sheet is direct about when it is not optional: “the protective bedding must be used when the stove is installed on e.g. tile floor with a water barrier treatment.” Harvia lists it for its wood-burning stove range with two exceptions, the 20 ES Pro/S and the Linear 22 ES. It measures 22 x 25 in and 2–3 in high, weighs 26.5 lb, and the feet let you level a stove on a floor that slopes to a drain.
Harvia WL200 Protective Sheath for Legend Wood-Burning Stoves
$399.00A 39.4 x 20.5 x 5 in black steel panel that shields a combustible wall from a Legend’s radiant heat. Harvia’s installation-options drawing takes the clearance at the stove body from 9.9 in with a bare smoke pipe down to 1.2 in with a WL200 fitted and a WL300 cover on an insulated Harvia chimney, provided the stones are piled so they cover the stove body and smoke pipe completely. Up to three panels can be joined.
Harvia WL590 Protective Sheath for Harvia Pro 20 RS/LS
$539.00A model-specific black steel sheath for the Harvia 20 RS/LS Pro. Harvia’s own safety-distance table drops the side and rear clearance from 11.9 in bare to 2.5 in with the sheath fitted, and asks for 16.7 in at the front instead of 11.9 in. 25.6 x 22.5 x 32.3 in, 18.73 lb, ships with its installation and operation manual.
Harvia WL650 Protective Sheath for Harvia Pro 20 ES
$531.00A three-sided steel sheath designed and approved for the Harvia 20 ES Pro/S.

Harvia WP220ST Pipe-Model Water Heater | 5.8 Gallon Stainless Steel
$727.00A 5.8 gal stainless water heater that sits on top of a wood stove with the smoke pipe running through it.

Harvia states it is compatible with all wood-heated Harvia stoves except the Harvia 50. 13.97 x 7.48 x 16.14 in.
