Who Holds SaunaBox's ETL Listing? What Intertek's Directory Shows (2026 Records Review)

Short answer

SaunaBox describes its Pulse PRO as "ETL Certified" and "ETL Listed." A November 6, 2026 search of Intertek's Directory of Listed Products returned no entry under the SaunaBox name. The one model number SaunaBox has put on an Intertek document, FRB-1M3 for the Solara, is ETL Listed under Youngy Health of Hefei, China, trade name Saunaking. No listing covering the Pulse PRO was located.

SaunaBox publishes no listee name, model number or control number for any product. This is a disclosure gap, not evidence that SaunaBox saunas are unsafe; the records below show exactly where verification stops.

What an ETL listing is, and what it is not

The ETL Listed Mark is Intertek's certification mark for North American product safety standards. For a residential sauna sold in the United States the relevant standard is UL 875, Electric Dry Bath Heaters; for Canada it is CAN/CSA-C22.2 No. 164, Electric Sauna Heating Equipment. A listing is held by a listee, the company that contracted with Intertek, and Intertek's program documents describe what that company takes on: an initial assessment of each manufacturing site, unannounced follow-up inspections where the product is built and labeled, and a control number, five to eleven digits, that identifies the manufacturing site and forms part of the mark printed on the product (source 14).

Three distinctions matter for everything that follows.

• A listing covers a configuration, not a name. The listing report describes the exact product; a brand's logo on the cabinet does not extend or narrow it.
• A brand can be in the directory without holding the listing. Intertek's Multiple Listing Program exists, in Intertek's words, for products certified for one company that "are produced for marketing under the name of another company." A Multiple Listee is "included in the Intertek's Online Certification Directory," without a visible link to the original applicant (source 13). A brand that has taken this route is findable by name.
• A test report is not a listing. Intertek issues test reports to many standards, including IEC 62233 for electromagnetic fields. Its reports carry a disclaimer that the report alone does not imply the product is under an Intertek certification program (source 4).

What SaunaBox publishes about ETL, page by page

SaunaBox's ETL language lives on its marketing pages. Its product pages make no ETL claim. Wording below is as published on November 6, 2026.

SaunaBox pages reviewed and the certification language on each

Across these six pages the two facts that would let a buyer verify an ETL claim, the listee name and the control number, do not appear.

What Intertek's directory returned

Intertek's Directory of Listed Products is free and public, and can be searched by company name, model number or standard (source 1). The directory page itself tells readers what to do when a product is not found: request a verification of certification from Intertek. A directory search is a first check rather than a final word, and the results below are reported with that limit in mind.

Directory searches run on November 6, 2026

The Youngy Health UL 875 entry (source 2) carries the trade name Saunaking and lists dozens of "Dry Sauna Room" model numbers, FRB-1M3 and FRB-2M3 among them, as tested to UL 875 and identified with the ETL Listed Mark. SaunaBox is not named anywhere in it.

The Solara: how the model number connects, and where the record stops

SaunaBox publishes no model number for the Solara. The number comes from SaunaBox's own evidence. Both Solara pages and the Pulse PRO page link Intertek test report 106542403MPK-001 (source 4), issued April 28, 2026 by Intertek's Menlo Park, California laboratory. The report identifies an "Infrared Sauna Room," trade name "Solara," model FRB-1M3, rated 120 V and 1,690 W, and names SaunaBox LLC in both the client and manufacturer fields.

Two public records therefore meet at one model number. SaunaBox's report says FRB-1M3 is the Solara. Intertek's directory says FRB-1M3 is ETL Listed to Youngy Health, a Hefei manufacturer founded in 1995 that sells saunas under its own Saunaking brand and holds the SAUNAKING trademark in the United States (sources 11 and 12). The same model number also appears on a far infrared sauna room sold under the VEVOR brand, specified at 1,400 W (source 10).

The record stops there, and the stopping point matters. A listing covers the configuration in the listing report. The Solara as sold carries full-spectrum heaters and a red light panel, and is rated 1,600 W on its product page and 1,690 W on its test report; the VEVOR unit carrying the same number is a 1,400 W far infrared cabin. Whether Youngy Health's FRB-1M3 listing covers the Solara's configuration cannot be confirmed from anything in the public record. Nor can the manufacturer: the directory points to a Hefei factory's catalog number, SaunaBox's report names SaunaBox LLC, and SaunaBox's pages do not say where the Solara is built.

The Pulse PRO: a badge without a locatable listing

The Pulse PRO is a fabric portable sauna with ThermoCell infrared panels, listed at $649 on sale on November 6, 2026, with a stated 160°F maximum and a 1,600 W rating (an FAQ on the same page says 1,500 W). It is the product SaunaBox labels "ETL Certified" and "ETL LISTED," and the one for which the least can be checked.

• Searches for SaunaBox, Sauna Box and Pulse PRO returned nothing in the directory.
• SaunaBox publishes no model number for the Pulse PRO, so no model search is possible.
• The two Youngy Health entries describe wooden sauna rooms and contain no model designation that resembles a fabric portable sauna.
• The only Intertek document linked from the Pulse PRO page is report 106542403MPK-001, the EMF test of the Solara cabin. No Intertek document for the Pulse PRO itself was located.

If a listing covers the Pulse PRO, nothing SaunaBox has published leads to it. The two routes to an answer are a listee name and control number from SaunaBox, or a verification request to Intertek.

"IEC 62233 Certified": a test report, read closely

SaunaBox's product pages present the Solara and the Pulse PRO as "IEC 62233 Certified" and "Low-EMF Verified by Intertek." The document behind both phrases is the same report, and it says less than the phrases suggest.

• Scope. One unit, model FRB-1M3, serial 133271. The 2-Person Solara and the Pulse PRO pages link the same document.
• Standard. IEC 62233:2005 (EN 62233:2008), a method for measuring magnetic fields from household appliances. The report records surface measurements and a weighted result against the standard's limit, and finds the sample complies. It does not report a milligauss figure at the seated position.
• Status. The report's own disclaimer states that it does not by itself imply the product is, or has ever been, under an Intertek certification program, and that use of the Intertek name or marks to sell or advertise the tested product requires Intertek's written approval.

Compliance with IEC 62233 is a real result for the unit tested. "Certified" is SaunaBox's description. And an EMF measurement report, whatever its result, is a different document from an electrical safety listing to UL 875.

How SaunaBox's ETL documentation compares

Sun Home Saunas, the brand connected to this publication (see the disclosure above), competes with SaunaBox and is used here as the benchmark because its directory entries can be opened and read in the same session. The comparison is limited to what each company publishes and what the directory shows; it is not a safety comparison.

Publicly checkable ETL documentation, November 6, 2026

Neither brand prints its control number online, and the directory alone does not show whether a company named on an entry is the original applicant or a Multiple Listee. What the directory does show is which brand name a buyer can find, and for SaunaBox the answer on November 6, 2026 was none.

Does this mean SaunaBox saunas are unsafe?

No. Nothing in this review supports that conclusion, and the limits deserve the same prominence as the findings.

• The FRB-1M3 listing under Youngy Health is a current ETL listing to UL 875. What is unconfirmed is whether the Solara's configuration as sold falls within it.
• A factory-held listing is a normal arrangement. Manufacturers hold listings for products built for other brands, and Intertek's Multiple Listing Program exists for that case. The gap here is disclosure: SaunaBox presents the certification as its own and gives buyers nothing to check it against.
• Absence from a directory search is not proof of absence. Intertek's own page invites verification requests for products that do not appear.
• Who manufactures the Solara is not established by these records.
• SaunaBox's OEKO-TEX, PFAS, Prop 65 and microplastics claims rest on separate documents and were not reviewed here.

This page will be updated if SaunaBox publishes a listee name and control number for the Pulse PRO, or confirms a Multiple Listee registration for the Solara.

How to verify any brand's ETL listing

1. Open Intertek's ETL Listed Mark directory and search the brand name as printed on the sauna. A brand that holds its own listing, or is registered as a Multiple Listee, appears.
2. If the brand does not appear, read the ETL mark on the product's rating label and search the control number beside it. The entry returned names the company Intertek holds responsible for that product.
3. Before buying, ask the brand for the listee name and control number covering the exact model and configuration. A brand that holds or is registered on a listing can answer in one line.
4. Check the standard shown on the entry: UL 875 for the United States, CAN/CSA-C22.2 No. 164 for Canada. An EMF report to IEC 62233 is not an electrical safety listing.
5. If the brand cannot answer, or the product is not found, request a verification of certification from Intertek at etldirectory@intertek.com or +1-888-347-5478, as its directory page instructs.

How we searched, so you can repeat it

Date: All searches and page reads were completed on November 6, 2026.

Directory: Intertek Directory of Listed Products, search form at ramuk.intertekconnect.com (source 1), default settings: search by All, no result limit, relevance order, fuzzy search off.

Queries run: sauna box; "sauna box"; "pulse pro"; FRB-1M3; "Sun Home". Each result count is reported in the table above.

SaunaBox pages read: The six pages in the page-by-page table, plus the linked Intertek report 106542403MPK-001 in full.

Intertek documents read: The Youngy Health and Sun Home Saunas UL 875 entries; the ETL Multiple Listee Agreement, form SFT-ETL-OP-19t; Intertek Semko's ETL Certification Rates 2025 general information.

Verification criteria: A claim was treated as verified only when a directory entry or an Intertek document connected the brand, the product and the standard. A marketing badge, a logo, or a report to a different standard did not meet that bar.

Limits: The public directory may lag Intertek's internal records. SaunaBox publishes no model or control numbers, so model-level searches were possible only for FRB-1M3. Product configurations covered by the Youngy Health listing cannot be read from the directory. This publication did not contact SaunaBox or Intertek for this review.

Frequently asked questions

Is SaunaBox ETL listed under its own name?

A November 6, 2026 search of Intertek's Directory of Listed Products located no entry under SaunaBox or Sauna Box. The Solara's model number, FRB-1M3, is listed under Youngy Health Co., Ltd (trade name Saunaking). Whether that listing covers the Solara as sold is unconfirmed.

Who holds the ETL listing for the SaunaBox Solara's model number?

Youngy Health Co., Ltd of Hefei, Anhui, China, under the trade name Saunaking, for UL 875 and CAN/CSA-C22.2 No. 164. The model number FRB-1M3 comes from SaunaBox's own Intertek EMF report.

Is the SaunaBox Pulse PRO ETL listed?

SaunaBox's marketing pages say "ETL Certified" and show an "ETL LISTED" badge. No listing for the Pulse PRO was located, SaunaBox publishes no model or control number for it, and the only Intertek document on its product page is an EMF test of the Solara.

What does "IEC 62233 Certified" mean on SaunaBox's pages?

It refers to Intertek test report 106542403MPK-001, which found that one Solara unit, model FRB-1M3, complied with the IEC 62233 EMF measurement method. The report states it does not by itself imply participation in an Intertek certification program, and it is not an electrical safety listing.

Who manufactures the SaunaBox Solara?

The public records do not establish it. Intertek's directory lists the model number under a Hefei manufacturer, Youngy Health; SaunaBox's own report names SaunaBox LLC as manufacturer; and a sauna carrying the same model number is sold under the VEVOR brand. SaunaBox's pages do not state a country of manufacture.

Is it a problem when a factory, not the brand, holds the ETL listing?

Not by itself. It is common, and Intertek's Multiple Listing Program lets the brand appear in the directory under its own name. The problem is marketing "ETL Certified" without giving buyers a listee name, model number or control number to check.

How can I check a sauna's ETL listing myself?

Search the brand name in Intertek's directory; if nothing appears, search the control number printed beside the ETL mark on the product label; and ask the brand for the listee name and control number before you buy. If none of that resolves it, request a verification of certification from Intertek.
