Heater Accessories
- SaunaLife Rounded Sauna Stones are sold only with the SaunaLife TITAN SL1 heater. Add TITAN to your cart first.
Accessories are where a sauna install stalls. The heater is on the pad, the room is clad, and the whole thing waits three weeks on a flue adapter nobody knew was needed. So we stock the small parts: stones, controls, chimney sections, clearance shields, safety rails and replacement elements for the heaters we sell.
Flue size is what we catch most. Harvia wood-burning stoves ship with 4.5 inch European pipe, so North American 6 inch pipe needs an adapter, and that is a part you want in the same box as the stove. Chimney kits, smoke pipes and roof fittings have their own section.
Clearances are the other one. A protective sheath lets a wood stove sit closer to combustible material than it otherwise could, and the stainless HIVE Reflector cuts wall-side clearance on HUUM’s round basket, both only in the configurations your current heater manual allows. Read the manual, not the internet, and when you are unsure round the clearance the safe way.
Stones ship with a heater order so we can match size and count to your model. Counts and sizes are model specific, so read your heater’s data label first rather than buying by the box.
Two more that get ordered late. A HUUM heater rated 12 kW or above needs the UKU extension box, and a panel extension cable moves a Xenio or Fenix controller well away from the heater. Both are separate orders.
Tell us your heater model at (844) 565-1113 and we will give you the part number.

SaunaLife Rounded Sauna Stones | 33 lb Box
$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 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.

$539.00A model-specific black steel sheath for the Harvia 20 RS/LS Pro.

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 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.
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.

Narvi Protective Wall 650×1150
$380.00With the help of protective walls, the sauna heater can be safely placed closer to the sauna walls. This is a great way of saving space and gives you more opportunities to place the sauna heater in the desired spot. By using protective walls, protective distances can decrease by 50%. The protective walls can be used with sauna heaters and light fireplaces.
