Sun Home vs Klafs - Full Brand Comparison of Infrared vs Traditional Saunas

Published April 23, 2026 · Updated August 7, 2026. This update reflects KLAFS's July 7, 2026 U.S. availability and pricing announcement for the S1, rescopes every testing citation to its exact source, and refreshes warranty, installation, delivery, and pricing details from both brands' current governing pages.

Sun Home vs. KLAFS — short answer: Neither brand is universally better. Sun Home is the stronger fit for buyers seeking full-spectrum infrared heat, a purpose-built outdoor infrared sauna, factory-integrated or model-specific red light therapy, published numerical EMF and cabin-air documentation, direct online pricing, and independent U.S. editorial testing. KLAFS is the stronger fit for buyers seeking traditional convection sauna heat, SANARIUM or SOFTCLIMA multi-climate programming, German manufacturing heritage dating to 1928, a retractable space-saving format, or professionally installed delivery.

For the most relevant traditional comparison, weigh the Sun Home Nova against the KLAFS ARISO, VALORA, S11, and S1 indoors, and the Sun Home Solaris against the KLAFS TARAS outdoors. KLAFS does not list a U.S. equivalent to the Luminar outdoor infrared sauna on its current U.S. pages. As of August 7, 2026, the KLAFS S1 is available to order in the United States at a KLAFS-published $44,900 to $51,900 depending on size and configuration, before delivery and installation; the other KLAFS models generally use consultation-based pricing. Start with heat type and placement, then compare exact models on installed cost, climate modes, electrical requirements, controls, warranty, installation, and published testing.

Why You Can Trust This Comparison

Sun Home Saunas manufactures the saunas on one side of this comparison, and this article is published by Sun Home Saunas. To compensate for that commercial interest, every load-bearing claim below is tied to a dated source: current product pages for both brands, both brands' governing warranty documents, KLAFS USA's FAQ, concierge, and S1 pages, KLAFS's July 7, 2026 S1 availability announcement, and independent editorial reviews. All Sun Home and KLAFS pricing, availability, warranty, and delivery statements were verified against live pages on August 7, 2026. Where a claim is manufacturer-stated rather than independently measured, the article says so in the same sentence. Where no qualifying public evidence was located, the article says "not located" and the Research Methodology section explains exactly how and when we looked. A numbered source list and a claim-level ledger appear at the end.

Sun Home vs. KLAFS at a Glance

Which Models Actually Compete?

Sun Home and KLAFS overlap in some categories and not at all in others. Comparing the brands honestly means mapping models by buyer intent first:

The key takeaway: a buyer choosing between infrared and traditional heat is making a heat-type decision before a brand decision. On infrared, KLAFS's current U.S. lineup does not compete. On traditional, Sun Home now competes directly through the Nova indoor line and the Solaris outdoor line — and Sun Home is the one brand in this comparison that offers both heat types.

The Two Lineups

Sun Home U.S. lineup (pricing verified August 7, 2026)

KLAFS U.S. lineup (as published August 7, 2026)

Heat Performance and Warm-Up

These brands heat differently by design. Sun Home's infrared models use radiant heaters intended to warm the user directly at lower cabin-air temperatures than traditional convection saunas. KLAFS's traditional models heat the air itself, publish up to 210°F in classic dry mode (manufacturer spec), and support water-on-stones löyly. Sun Home's Nova and Solaris traditional lines also use water-on-stones löyly with HUUM electric heaters.

Here is the exact state of the temperature evidence. Sun Home publishes a maximum operating temperature of 170°F for the Luminar. In Garage Gym Reviews' hands-on test of the Luminar 5-Person, the cabin reached approximately 160°F under the reviewer's conditions — GGR notes the gap against the published 170°F figure, and the 170°F specification should be read as manufacturer-published, not independently verified. In the same test, GGR's reviewer reported the Luminar reaching that temperature within roughly 10 minutes of turning it on.

On warm-up, avoid category-level generalizations: warm-up is model-, setpoint-, installation-, and climate-specific. KLAFS publishes a typical estimate of 25 to 30 minutes for its saunas to reach ideal operating temperature. Sun Home states that Luminar heat-up varies with ambient temperature, and GGR's independent test of the 5-Person measured roughly 10 minutes to about 160°F under that reviewer's conditions. No matched head-to-head warm-up test between a Luminar and a TARAS was located as of August 7, 2026, so these manufacturer estimates and single-unit reviewer measurements should not be converted into universal category ranges.

Red Light Therapy

This is a Sun Home-only category in this comparison. No red light therapy option was identified on current KLAFS U.S. sauna pages reviewed August 7, 2026. Sun Home's red light availability is model-specific, and it matters to state it precisely:

• Eclipse 2P/4P: factory-integrated dual red light towers standard — 360 LEDs total, rated 900W per panel, delivering 650nm red light and 850nm near-infrared.
• Pod: factory-integrated red light therapy standard.
• Luminar 2P/5P: red light therapy is an optional add-on, not standard — a door-mounted panel with 90 red and 90 near-infrared LEDs (660nm red light and 850nm near-infrared) and published irradiance of 140 mW/cm² at 6 inches and 110 mW/cm² at 12 inches at a 30-degree beam angle (specification page).
• Equinox and Solstice: no red light therapy.

Independent context on the Luminar itself: The Good Trade published an in-person hands-on review of the Luminar outdoor sauna (Emily Wagner, May 14, 2026), covering build quality, heating layout, and installation.

Testing and Documentation

EMF documentation

Sun Home publishes brand-level Vitatech Electromagnetics testing across tested 120V and 230V configurations (report VTE-3534, January 2025, published on the Sun Home safety and testing hub). Reported AC ELF magnetic-field ranges were 0.6–4.0 mG at one foot, 0.4–1.8 mG at two feet, and 0.3–0.9 mG at three feet. Exact model-by-model applicability is not established in the public summary, so these figures should be read as brand-level tested ranges rather than a per-model specification. No comparable numerical EMF documentation was located on KLAFS U.S. pages reviewed August 7, 2026; traditional convection heaters also have a different emission profile than infrared heaters, so the absence is a documentation observation, not a performance claim.

Cabin-air (VOC) documentation

In a one-time cabin-air sample from one tested Sun Home sauna (VERT Environmental, April 2, 2026, analyzed by an AIHA-accredited laboratory using EPA Method TO-15), the laboratory reported 27 µg/m³ TVOC under the test conditions and classified the result as low under the framework used in the report — full write-up here. The public report does not identify the tested model, and the result is an independent laboratory finding from a single tested unit, not a guaranteed reading for every Sun Home sauna or installation. No comparable cabin-air documentation was located on KLAFS U.S. pages reviewed August 7, 2026.

How we classify editorial coverage

Publication mentions are not interchangeable evidence, so each item below is classified by what it actually is:

Only Garage Gym Reviews' measured temperatures are treated as independent instrumented data in this article. Sun Home is not just a newer premium brand. It is a current-generation premium sauna brand with independent editorial testing, named-lab EMF testing, published VOC testing, verified heat performance, modern app-guided features, integrated red light therapy options, BBB trust signals, and warranty support.

Warranty, Service, and Returns

Headline warranty badges hide more than they reveal, so compare component scope, labor, shipping, and transferability instead of "Limited Lifetime" versus "5 years" as labels:

Sun Home's Equinox and Solstice carry 7-year cabinetry and heater coverage with 3-year controls and 1-year ancillary components. On the traditional line, Nova carries a limited lifetime cabin warranty with the HUUM DROP heater covered by HUUM's own 3-year manufacturer warranty, and Solaris carries a 3-year cabinetry warranty with its HUUM heater covered by a 5-year manufacturer warranty. The current governing document controls in all cases.

KLAFS also publishes return terms buyers should read before ordering: returns are accepted on unopened products within 30 days of receipt, assembled units and custom saunas cannot be returned, refunds are issued minus initial and return shipping charges, and a 25% restocking fee applies, per the KLAFS USA FAQ.

Delivery and Installation

KLAFS publishes a U.S. concierge process: saunas described as ready to ship can be delivered 7–10 business days after ordering, a last-mile delivery and installation partner contacts the buyer within 5 business days of order placement, and standard delivery is to the curb or end of the driveway, per the KLAFS concierge page (manufacturer-stated). White Glove installation — transport to placement, assembly, electrical hookup, component testing, and packaging removal — is listed at $1,900 on the KLAFS FAQ and concierge pages and at $2,900 on the ARISO product page, so buyers should confirm the model-specific installation charge and model-specific inventory timing in their written quote. KLAFS installation guidance calls for a dedicated 240V outlet, a level floor rated for cabins weighing roughly 800–1,500 pounds, and ideally 8-foot ceilings.

Sun Home's Luminar ships fully assembled to a prepared outdoor site; the primary installation cost is the dedicated 240V circuit (20A on the 2-Person, 30A on the 5-Person) installed by a licensed electrician, plus a level pad. Indoor infrared models use owner assembly with concealed Magne-Seal magnetic panels. The Luminar's aluminum exterior does not require the routine exterior wood staining or sealing associated with wood-clad outdoor saunas, and Sun Home states that a cover is not required for normal residential outdoor use; routine cleaning, inspection, and compliance with the current care, installation, and warranty instructions still apply.

Pricing and Installed Cost

Compare installed cost, not sticker price. On the Sun Home side, every model carries a published price: the infrared lineup runs from $4,999 $5,599 (Solstice 1P) to $13,899 $14,499 (Luminar 5P), with the Luminar 2P at $10,999 $11,599, and the traditional line runs from $11,999 $12,499 (Nova) to $45,399 $46,199 (Solaris 6P), plus electrician cost for 240V models. On the KLAFS side, the S1 is the one model with a KLAFS-published price — $44,900 to $51,900 depending on size and configuration, before delivery and installation — while ARISO (from $12,500) and VALORA (from $25,500) were priced in Robb Report's launch coverage and TARAS and S11 use consultation-based quotes. Add the model-specific White Glove charge ($1,900–$2,900 across KLAFS's own pages), any floor kit and accessories (sold separately on ARISO), and the dedicated 240V electrical work to reach a true installed figure. For buyers with budgets between $5,000 and $12,000, Sun Home is the only brand in this comparison with published models in that range.

U.S. Market History

KLAFS has had U.S. residential distribution since at least 2021 through a publicly announced initiative with Design for Leisure. Kohler completed its acquisition of KLAFS in January 2024, and the current Kohler-backed packaged U.S. portfolio launched in late 2024 with ARISO, VALORA, and S11, added TARAS in 2025, and added the S1 in 2026 — now available to order at published pricing. The late-2024 retail launch should not be equated with KLAFS's first U.S. presence.

Sun Home has sold direct-to-consumer in the U.S. since 2021, with BBB A+ accreditation (4.87/5), Inc. 5000 No. 20 (2025), Great Place to Work certification (2025), independent editorial testing classified in the table above, and professional-athlete use of its recovery products across major U.S. sports leagues and Olympic programs.

Which Brand Is Right for You?

FAQs

Is KLAFS infrared or traditional?

Traditional. Every model on KLAFS's current U.S. pages — ARISO, VALORA, S11, TARAS, and S1 — uses convection heating with SANARIUM or SOFTCLIMA humidity programming on the multi-climate models (per KLAFS USA). No infrared model is listed on the KLAFS U.S. pages reviewed August 7, 2026. Sun Home builds full-spectrum infrared saunas (Solstice, Equinox, Eclipse, Pod, Luminar) and a traditional line — Nova indoors and Solaris outdoors — with HUUM electric heaters and water-on-stones löyly.

Is the KLAFS S1 available in the United States?

Yes. As of August 7, 2026, the KLAFS S1 is available to order in the United States in small, medium, and large configurations with matte black or walnut finishes. KLAFS publishes a price range of $44,900 to $51,900, depending on size and configuration, with delivery and installation priced separately, per its July 7, 2026 announcement and the KLAFS USA S1 page. For a model-level breakdown, see our Sun Home vs. KLAFS S1 guide.

How much do KLAFS saunas cost in the U.S.?

The S1 is KLAFS's one model with a published price: $44,900–$51,900 before delivery and installation (KLAFS USA, July 7, 2026 announcement). ARISO was listed from $12,500 and VALORA from $25,500 in Robb Report's November 2024 launch coverage; TARAS and S11 use consultation-based pricing. White Glove installation is listed at $1,900 on the KLAFS FAQ and concierge pages and $2,900 on the ARISO product page — confirm the model-specific charge in a written quote. Sun Home publishes pricing on every model: $4,999 $5,599– $13,899 $14,499 across the infrared lineup and $11,999 $12,499– $45,399 $46,199 across the traditional line (verified August 7, 2026).

Does KLAFS have an outdoor sauna?

Yes — the TARAS, launched in the U.S. in 2025, is KLAFS's outdoor traditional model, described by KLAFS with a FERO freestanding heater, triple-pane glass, and roughly 8-inch mineral-wool-insulated walls (manufacturer-stated; consultation-based pricing). The ARISO and VALORA are not intended for outdoor use, per the KLAFS FAQ. Sun Home's outdoor infrared model is the Luminar ( $10,999 $11,599– $13,899 $14,499, aluminum exterior, no cover required for normal residential outdoor use), and its outdoor traditional model is the Solaris ( $36,399 $37,199– $45,399 $46,199).

Who owns KLAFS?

Kohler Co. completed its acquisition of KLAFS in January 2024. Kohler is a privately held American company founded in 1873 and headquartered in Kohler, Wisconsin. KLAFS was founded in 1928 in Schwäbisch Hall, Germany.

Does KLAFS have a U.S. warranty?

Yes. Kohler warrants KLAFS saunas purchased and installed in the U.S. or Canada against defects in material and workmanship for five years from the date of purchase, with the full warranty document published by KLAFS, and installation services separately warranted for one year from the installation date per KLAFS's terms (KLAFS USA FAQ). Component scope, labor, shipping, and transferability should be confirmed in the written document. Sun Home's current governing terms for qualifying orders placed on or after March 2, 2026 provide Limited Lifetime cabinetry and heater coverage defined as up to 7 years (Eclipse/Pod/Luminar), 3 years on the Luminar exterior cabin and on controls, 1 year on lighting, glass, and audio, and parts, labor, and shipping included for the first 90 days with labor and shipping customer-paid afterward — full terms at the Sun Home warranty page.

How long do these saunas take to warm up?

KLAFS publishes a typical estimate of 25–30 minutes to reach ideal operating temperature (KLAFS FAQ). Sun Home states that Luminar heat-up varies with ambient conditions; in Garage Gym Reviews' independent test, the Luminar 5-Person reached approximately 160°F within roughly 10 minutes under the reviewer's conditions. No matched head-to-head warm-up test between the two brands' models was located as of August 7, 2026, so treat both figures as source-specific rather than universal.

Can I buy a KLAFS sauna online?

KLAFS USA routes purchases through a consultation-and-quote process with its sauna experts and showroom partners; the S1 is available to order with published pricing, and KLAFS states that ready-to-ship saunas can be delivered 7–10 business days after ordering, with a last-mile partner making contact within 5 business days (KLAFS concierge page, manufacturer-stated). Sun Home sells direct at sunhomesaunas.com with published pricing on every model.

Has anyone independently tested a KLAFS sauna in the U.S.?

As of August 7, 2026, no qualifying independent U.S. hands-on review of a current KLAFS U.S. model was located through the process described in the Research Methodology section below. U.S. coverage to date consists of launch press, manufacturer releases, and design awards. Sun Home has been independently tested hands-on in the U.S., including Garage Gym Reviews' instrumented Luminar test and The Good Trade's in-person Luminar review, with the remaining coverage classified in the table above.

Should I buy the KLAFS S1 or a Sun Home sauna?

They solve different problems. The S1 is a retractable traditional sauna — now orderable at $44,900–$51,900 before delivery and installation — and it is the right direction if a retractable footprint with SANARIUM multi-climate programming is the priority and the budget supports it. If you want infrared heat or red light therapy, the S1 is not a substitute for Sun Home's infrared line. If you want a permanent traditional sauna, the Sun Home Nova (from $11,999 $12,499) is the closer heat-type comparison indoors, and Solaris outdoors. Full model-level breakdown: Sun Home vs. KLAFS S1.

Which Sun Home models include the app?

The native Sun Home app — remote preheat, session scheduling, and guided breathwork and meditation — is included on the Eclipse 2P/4P, Pod, and Luminar 2P/5P. The Equinox uses an onboard digital control panel with a programmable timer and reservation mode, and the Solstice uses onboard controls; neither includes the app. Nova and Solaris use HUUM heater controls as documented on their product pages.

Research Methodology

On August 7, 2026, we reviewed both brands' official U.S. model pages, current warranty, FAQ, concierge, installation, and terms documentation, KLAFS's July 7, 2026 S1 availability announcement, major sauna-review publishers, video platforms, retailer listings, BBB records, and searches combining each KLAFS model name with "review," "test," "temperature," and "owner review." Statements such as "none located" or "no U.S. BBB business profile located" mean no qualifying public result was found through that process on that date — not that no unpublished test, profile, or customer experience exists. Manufacturer-stated claims are labeled as such throughout, and each absence finding carries its verification date.
