Almost Heaven Worthington 4-6 Person Indoor Sauna (Nordic spruce, 8 kW KIP heater with dials)

1. Heat & research 30% of the rating 4 of 5

   An 8 kW Harvia stone heater with about 44 lb of stones that takes water on the rocks; a dealer says it reaches 195 °F in under an hour and the manual calls 150 to 170 °F usual, with no measured cabin temperatures.

2. Materials 25% of the rating 4 of 5

   Solid Nordic spruce with stainless hinges and fasteners and no finish named, but the manual suggests wood glue for the bench supports, how the panels are joined is not stated, spruce can weep pitch and we found no emissions test.

3. Safety & EMF 20% of the rating 3 of 5

   Harvia says the base KIP heater carries a UL certificate, which we could not check, while the Spirit option’s part number fits an ETL listing we could open; neither covers the room.

4. Trust 10% of the rating 3 of 5

   No recall or Prop 65 notice found and a lifetime warranty on the room, but the brand’s copy says “USA-made” while this model’s page says Romania, and its FAQ lists detoxification and burned calories.

5. Value 15% of the rating 4 of 5

   About $870 to $1,300 a seat for 4 to 6 at the 30%-off sale price ($1,240 to $1,850 at the $7,415 list price), with a heater and stones included, plus an electrician for a hard-wired 240 V, 40 A circuit.

The rating, 3.7 of 5, is the weighted average of these scores. See how we rank saunas and our standard.

• Finnish Sauna Builders (retailer) (opens in a new tab) approx. $5,191 with the 8 kW KIP heater; approx. $7,690 with a 9 kW Spirit or Virta. A retailer, not the maker. The same price as the maker’s on the day we looked. Marked down from $7,415. Its copy says 1-3/8 in boards and “handcrafted in the USA”, which differs from the maker’s page.
• My Sauna World (retailer) (opens in a new tab) approx. $5,645 (marked down from $7,858 on the page). A retailer, not the maker. One option; the page does not name the heater model. Offers a layaway plan with 50% down, refundable before the order ships.
• Sauna Place (retailer) (opens in a new tab) approx. $5,890 (marked down from $7,415 on the page). A retailer, not the maker. Titled as a 6 person sauna with an 8 kW heater; its resources link a Harvia KIP manual. It says it ships in about 5 weeks (as of October 2026) with free curbside delivery to the lower 48 states, though its web address still says “ships in 2 days”.

Prices as we saw them on November 3, 2026. They change often. These links carry no tracking code and earn us nothing.

1. Nordic spruce (maker), 1-1/2 in tongue-and-groove walls and roof in pre-assembled panels; no finish is named, and we could not find out how the panels are joined. The manual suggests a dab of wood glue (not included) in the pin holes of the lower bench’s supports
2. Tempered, tinted glass door and window (a dealer says 5/16 in thick)
3. Stainless steel hinges and fasteners (maker); a metal post supports the bench, and the lower bench’s legs have plastic floor protectors (manual)
4. Interior LED light on a 110 V plug
5. 8 kW Harvia KIP electric heater with dials: stainless steel with a stone guard, holding about 44 lb (20 kg) of stones per Harvia’s datasheet, with sauna stones included (the page says “best-in-class heater and sauna stones”); the Spirit and Virta heaters cost more
6. No floor: it uses the floor of your room

• Paid certification Intertek (ETL directory, Harvia Finland Oy heaters)

  Lists Harvia’s Spirit pattern (HSPE, then 45 to 90, U1 or U3, then M, S, R, BR, G or W) to UL 875, with a sister listing to CAN/CSA E60335-2-53. The Spirit part number HSPE80U1M fits it. We found no KIP code in any of Harvia’s 11 entries in this directory; Harvia’s own US page names a UL certificate for the KIP instead, which would be in UL’s directory. The listing covers heaters, not the sauna room, and shows no certificate number or date. Open ↗ (opens in a new tab)

Is the cheaper KIP heater safety-listed?

Harvia says so, but we could not check it. Harvia’s US page for the Kip80B (opens in a new tab) lists the certificate as UL, which would be in UL’s own directory, not Intertek’s, and we could not search UL’s. A search of Intertek’s directory by company name returns 11 Harvia entries (heaters, controls and their CSA equivalents), and none names a KIP model code. Almost Heaven’s part codes for the 8 kW KIP options (AHKIP80PKG, JH80W2401I) are not in Harvia’s UL 875 listing (opens in a new tab), which covers other Harvia families. The Spirit option’s code, HSPE80U1M, does fit it. UL’s own directory (Product iQ) blocks automated reads, so we could not search it. Ask Almost Heaven for the listing of the exact heater before you buy.

Is it made in the USA?

Not according to its own page. The Worthington page (opens in a new tab) lists the country of origin as Romania, while the brand’s FAQ (opens in a new tab) says Almost Heaven “builds USA-made saunas” and Finnish Sauna Builders says this model is “handcrafted in the USA”. A competing retailer’s review also lists it among the Romania-made indoor rooms. Ask which applies to the one you order.

Will the spruce weep resin, and does the wood give off fumes?

The maker’s FAQ (opens in a new tab) says Nordic spruce has a small amount of pitch that can seep from the boards when hot, and calls that normal. The page names no glue, stain or varnish, though the manual (opens in a new tab) suggests a dab of wood glue (not included) in the pin holes of the lower bench’s supports, and the maker advises against sealants or varnish on the floor because they can contain chemicals. We found no emissions or odor test for the wood.

Do owners complain about Almost Heaven saunas?

A competing retailer’s tally of r/Sauna posts (Sauna Marketplace (opens in a new tab), updated 2026-09-24) counted 129 positive, 10 mixed and 3 negative verdicts among 142 owners; the 59 indoor-room owners were 57 positive, 1 mixed and 1 negative. Barrel owners most often raised rain and leaks (24 owners) and gaps or warped parts (12), and it mentions one owner whose heating elements were replaced at no cost. The group is self-selected, the site sells competing saunas and Harvia heaters, and Harvia owns Almost Heaven, so weigh it accordingly.

Does the lifetime warranty last for life?

The warranty page (opens in a new tab) gives a limited lifetime warranty against manufacturing defects on the sauna room, replacing parts at no charge, and it does not transfer to a second-hand buyer. The Harvia heater has 1 year on the heating elements and 5 years on other components, and electrician costs are not covered.

Does its marketing claim detox benefits?

The Worthington page does not. The FAQ (opens in a new tab) lists detoxification and burned calories among sauna benefits. Our detox page says metals appear in sweat but no trial shows a lower body burden. The site also features a “Doctor-in-Residence”, Dr. Emilia Vuorisalmi, with a page (opens in a new tab) of her favorite saunas and a monthly blog; it does not say how she is paid.

• It is one of the least expensive ways we found to own a traditional indoor sauna with a heater included: about $5,191 for 4 to 6 seats, and three dealers sell it at $5,191 to $5,890.
• The materials are plain and named: solid Nordic spruce tongue-and-groove, stainless steel hinges and fasteners and tempered glass, with no stain or varnish named and only a dab of wood glue suggested for the bench supports.
• The Spirit option matches a listing we could open. Almost Heaven’s code for it, HSPE80U1M, fits a Harvia pattern in Intertek’s ETL directory (UL 875), and Harvia says the base KIP is UL certified.
• The maker gives clear numbers and a public construction manual: inside and outside sizes, a 40 A hard-wired circuit, 90 °C copper wire and a 30-minute session limit.
• A limited lifetime warranty on the room and 5 years on most heater parts, in writing.

• The base price uses the KIP heater with dials, whose UL certificate we could not check, and it holds only about 44 lb of stones. The Spirit option adds about $2,500 and matches a listing we opened.
• It is made in Romania per the maker, and its copy elsewhere says USA-made. Ask.
• Seats 4 to 6, but the maker’s inside size is 77 by 58 in, so six is likely tight.
• The warranty does not transfer and leaves out electrician costs. It ships within 4 weeks.
• It needs a licensed electrician to hard-wire a 240 V, 40 A circuit, and a floor that suits sauna water: tile, concrete, vinyl or laminate, per the maker.
• The price was a sale price on the day we looked (30% off from $7,415, under a Pre-Black Friday banner), and the dealers’ prices are marked down too.
• Ask a doctor first if you have heart disease or are pregnant, and skip alcohol (see our hot baths page).
