Heater Accessories
Stones, controllers, chimney adapters, safety rails and embedding flanges for the heaters we sell. Stones ship with a heater order so size and count match your model. A HUUM heater rated 12 kW or more needs the UKU Extension Box. Harvia wood stoves ship with European 4.5 inch pipe, so a North American 6 inch chimney needs the adapter. An embedding flange sets a heater into a raised bench, which puts your feet up near the stones. Controllers and chimneys and venting have their own pages.

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 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 sauna layout works. This stainless Heat Shield clips onto TITAN SL1 and reduces the required sauna 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.

$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.

Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.

Use the exact drawing before ordering, and plan sauna stones separately unless the selected cart line explicitly says they are included.

$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 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.

$207.00A black rustproof steel cage, 9.8 in. across and 15.8 in. tall, that holds a column of stones around the connective flue above a Narvi wood stove. Narvi’s reasoning: the heat of the flue gets used better, and the steam lasts longer because the water flows from the cage down onto the heater’s own stones. Cages can be stacked. Stones are not included, and the 4–6 in stones Narvi specifies for the heater basket are too large for the cage.
