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.
