A wood stove is sized by room volume and installed around a chimney, so check these points with your installer before you pick a version.

Perfect for sauna rooms from 212 - 459 ft³
Light the fire, close the glass door, and a pillar of stones soaks up the heat. The Harvia Legend 150 (WK150LD) is a 16 kW wood-burning sauna stove for rooms of 212 to 459 cu ft (6 to 13 m³). It needs its own 4.5 in (115 mm) chimney.
Pick one of six versions. The stove-only WK150LD is loaded inside the sauna. The 150 SL (WK150LDSL) is loaded from the next room through a masonry wall. The four packages add a chimney kit, extension, floor bedding, side sheath and stones. SS packages use a stainless chimney and BK packages a black one. WH packages add a water heater. The stove itself is black steel in every version.

Check before ordering
Harvia's safety distances only apply when stones fully cover the stove body. Bare steel can overheat nearby walls even outside those distances.
The Before You Order tab lists the room, chimney, floor and wall checks for your installer. Send us your room size and chimney route and we will match the right version.

Harvia rates the Legend 150 WK150LD for 6 to 13 m³ rooms, which is 212 to 459 cu ft. Bare glass, stone or tile walls and solid log walls make a room act larger, so a room near the top of the range may need the Legend 300. The Before You Order tab shows how to adjust your figure.
Both are 16 kW stoves for the same room size. The Legend 150 SL (WK150LDSL) has a fire chamber extension that goes through a masonry wall, so you feed it from the next room. It is 28.7 in (730 mm) deep instead of 20.9 in (530 mm). The SL needs a wall opening that meets Harvia's sizes.
SS packages come with a stainless steel chimney kit and extension. BK packages come with the same parts in black. WH packages add the WP250LD water heater and a short smoke pipe. The Legend 150 stove is black steel in every version, so SS and BK only change the chimney finish.
The WK150LD needs its own 4.5 in (115 mm) T600 chimney, either a masonry flue or Harvia's WHP1500 steel chimney. Harvia does not allow a shared flue. The steel chimney must stand straight up, no taller than 16.4 ft (5 m). The SS and BK packages include the kit plus a 3.3 ft extension. Stove-only buyers order it separately.
It depends on the floor. Thick bare concrete needs nothing extra. Tile glue and wood can be damaged by the heat, so Harvia calls for its WL100 bedding under the stove, plus a nonflammable plate on a wooden floor by the door. Every package version includes the WL100. Exact figures are on the Before You Order tab.
Harvia rates the Legend 150 with smaller side and back distances than many wood stoves, so benches can sit fairly close. The front needs the most space. Every figure, including the gap to brick or concrete walls, is on the Specifications tab. Those figures assume the stones hide the stove body completely.
The WK150LD takes up to 264 lb (120 kg) of stones, 4 to 6 in (10 to 15 cm) across. That is six 44 lb boxes. The four packages include them. Stove-only and SL buyers add their own stones. Harvia's manual asks you to cover the whole stove body so no bare steel shows.
Use dry split wood up to 13.8 in (35 cm) long. Harvia suggests 3.1 to 4.7 in (8 to 12 cm) pieces to start and 4.7 to 5.9 in (12 to 15 cm) pieces to top up. Do not burn painted or treated wood, chipboard, pellets, coal or plastic. Large loads of dense wood shorten the stove's life.
Yes. Harvia's WP250LD sits on top of Legend stoves and holds 6.6 gal (25 L). The WH packages include it, and stove-only buyers can add it later. It needs about 33 lb (15 kg) of 2 to 4 in (5 to 10 cm) stones, sold separately. Water reaches boiling, so mix it with cold water. Never heat the tank empty.
The Manuals tab links Harvia's installation and use manual for the whole Legend series, edition Y05-0136 09/25, and the WK150LD data sheet. The Legend 150 figures sit in Table 1 of the manual. Give both documents to your installer before work starts.
Harvia's WK150LD data sheet lists the SASPO241 Legend safety railing as the matching accessory for this stove. It puts a rail around the hot stone pillar so bathers do not brush against it. It is sold separately and works with both the Legend 150 and 150 SL. See the Optional Upgrades tab.
Harvia US covers wood-burning heaters for 2 years in family use and 6 months in commercial use. Harvia accessories such as the chimney kit get 2 years in family use and 1 year in commercial use. Sauna stones are not covered. Check the stove for shipping damage on arrival and report it within 7 days.
Harvia says to rearrange the stones at least once a year, more often if the sauna is used a lot. Remove broken pieces and stones under 4 in (10 cm), and replace them with whole ones. Empty the ash box before each fire and sweep the chimney at regular intervals.
Buying for yourself, spread the cost through Affirm at checkout. Buying for a gym, clinic, spa, or studio, apply with one of four business lenders and put the whole room on a single application.
RecovAthlete has no control over any financing decision. Approval is based on your creditworthiness and is solely the lender's decision.
Affirm at checkout. Rates run 0% to 36% APR based on your credit profile. Soft check to prequalify, so no impact on your score. No prepayment penalty.
Brickhouse Capital, Reliant Capital, Acorn Finance, or KWIPPED. Apply with two of the four and compare. Financed equipment can qualify for a Section 179 deduction. Confirm with your accountant.
Every page below has real prices, real monthly payment examples, and the lender comparison for that category. Pick the one you are buying.
Most business buyers are not buying one machine. They are building a room. Sauna, cold plunge, red light, vibration, hyperbaric, cryotherapy, and halotherapy all finance on the same paper through the same four lenders, and RecovAthlete quotes every category on one purchase order.
That means one freight schedule, one install window, and one financing application instead of six. It also gets you a better rate, because a bigger number on one application beats six small ones with six hard inquiries.
See commercial recovery equipment financing, or call 866-861-6317 and we will price the room.
| Lender | Type | Amount | Speed | Best for |
|---|---|---|---|---|
| Affirm | Consumer, at checkout | Order total | Seconds | Personal purchases. 0% to 36% APR based on credit. Soft check to prequalify. |
| Brickhouse Capital | Direct equipment lender | Up to $250K on a one-page application, $1M+ with financials | ~24 hours | A full room or a full floor. Credit decisions made in-house. Tied to the business, not your personal credit report. |
| Reliant Capital | Lender and broker | Up to $500K application-only, $5M with financials | 2 to 4 hours | Medical, aesthetic, and wellness. Deferred payment options. New or used equipment. |
| Acorn Finance | Lending marketplace | $1,000 to $100,000 | 60 seconds to prequalify | Comparing offers. One application goes to 30 or more lenders with no impact to your score. |

Pay in 4 splits the purchase into four interest-free payments charged every two weeks. Monthly installments spread the cost over a longer term, with rates from 0% to 36% APR depending on your credit profile. You see the exact terms before you agree to anything. No origination fees, no prepayment penalty, no late fees.
Prequalification does not. Affirm and Acorn Finance both run a soft check to show you offers, which has no impact on your score. Proceeding with a monthly installment plan or a business loan may involve a hard inquiry. That is why it pays to prequalify with more than one lender first and only proceed with the best offer.
Yes, and for most business buyers it is the better route. Brickhouse funds up to $250,000 on a one-page application with no financial statements. Reliant approves in 2 to 4 hours. Business financing is usually tied to the business rather than your personal credit report, and financed equipment can qualify for a Section 179 deduction. Confirm the tax position with your accountant.
No. This is the most common and most expensive mistake. Separate applications mean separate hard inquiries, separate payments, and a worse rate on each, because every individual ticket is small. Get one quote from RecovAthlete covering everything you are buying, including freight, and put that single number on one application.
Financed equipment can qualify. Section 179 lets US businesses deduct the cost of qualifying equipment in the year it is placed in service, and financing the purchase does not by itself disqualify it. The equipment must be in service, not merely ordered, within the tax year. Annual limits and eligibility rules are set by the IRS and change year to year, so consult your accountant.
Freight, yes. On Affirm it is part of the order total at checkout. On business financing, put freight on the RecovAthlete quote and the whole quote amount goes on the application. Installation and room construction are harder, because some equipment lenders will not fund non-equipment costs. Ask the lender before you sign.
Yes. Affirm charges no prepayment penalties. Acorn Finance and most business lenders also allow early payoff without penalty.
Tell us what you are buying and whether it is personal or for a business. We will point you at the right two lenders and quote freight and install as one number, which is also the number that goes on the application.
