Sauna360 Recalls 41,580 Infrared Saunas; Tylö Bench Recall Expands After First Repair Failed

The U.S. Consumer Product Safety Commission published two Sauna360 recalls on September 17. One covers about 41,580 infrared and hybrid sauna rooms and infrared kits in the United States, plus about 6,758 in Canada, sold over 13 years through Costco and pool and spa dealers. The other reopens the Tylö bench recall from last year, raises the count from about 1,000 rooms to about 6,000, and says in the hazard line that the first repair did not work.

Both notices tell owners to stop using the sauna now. Neither gives a date for parts.

The two populations overlap. Kiruna Hybrid 2 and Kiruna Hybrid 3 rooms appear on both lists, and Sauna360's own FAQ says it expects to handle both problems in one technician visit. So the recalled units cannot simply be added together.

The Infrared Recall Is the Larger One by a Wide Margin

The hazard is electrical. In the CPSC's words, "the infrared panels in the saunas and kits can short circuit, causing them to overheat, posing a risk of serious injury from fire and burn hazards." Sauna360 has logged 67 reports of overheating, melting, charring or burning. No injuries have been reported.

The sales window is the number that makes this recall unusual for the sauna trade: May 2013 through July 2026, at $6,000 to $13,000, through "Costco stores and pool and spa dealerships nationwide and online at Costco.com and other online sites." Thirteen years of installed base, across eight brand names and one category of unbranded rooms.

The brands named in the notice are Finnleo, Helo, Radiant Health, Sauna360, Saunatec, Tylo, Tylohelo and a "No Brand" S Series. Amerec appears in the separate list of infrared kits. Owners of custom and semi-custom rooms are told to look for the words "Saunalogic," "Infralogic," "Carbonflex," "Aspire," "Bliss" or "Tylö" on the control panel, because the panels were sold into rooms that carry no sauna brand at all.

The fix is not a part swap on a subset. Sauna360's infrared recall FAQ describes the remedy as putting "new circuit boards on every sauna with a new fuse connected to every panel of every sauna room no matter the brand or the model." That is a control board and a per-panel fuse in roughly 48,000 rooms across two countries, each one an in-home visit by an authorized technician.

Costco is named only in the "Sold At" line. The notice lists Sauna360, Inc. of Cokato, Minnesota as the importer and carries no distributor or retailer field, so Costco is not a party to the corrective action. The remedy on the notice is the single word "Repair." No refund, replacement or credit appears anywhere in the CPSC notice or in the company FAQ.

The Bench Recall Comes Back Six Times Larger

In October 2025, Sauna360 recalled about 1,000 Tylö Halmstad and Kiruna Hybrid rooms after seven reports of benches breaking and one head and neck injury. We covered that notice in our April analysis of the affected sales window. The remedy was a professional installer retrofitting the benches with additional hardware, plus a revised manual carrying a weight limit.

The September 17 expansion states the outcome plainly in the hazard field: "The saunas contain a bench that can collapse, posing a fall hazard to consumers. The previous recall repair was ineffective; a new repair is now being offered."

What changed:

That sales window is the line dealers will read twice. The recalled rooms kept shipping through July 2026, about nine months after the October 2025 recall was announced.

The expansion also tells owners who already took the first repair to stop again: "Consumers should stop using the saunas immediately, even if they received the 2025 recall remedy and contact Sauna360 for another free repair." The new retrofit adds "additional hardware and supports," a change in wording from the hardware-only retrofit of 2025. CPSC does not say whether any of the 77 new reports came from a bench that had already been retrofitted, and Sauna360 has not said either.

The serial ranges widened in both directions. Halmstad now runs CSFxxABTRxx-V1-4296 through CSFxxABADTRxx-V1-18577, plus a second band from SFxxABTRxx-V1-48413 through SFxxABTRxx-V1-48444. Kiruna Hybrid runs CSFxxABISxxTL-V1-4674 through CSFxxABADISxxTL-V1-18503. The 2025 bands sit inside the new ones, so no unit recalled last year falls out of scope. The serial label is under the upper bench on the left side for Halmstad rooms, directly above the electrical contactor box, and on the right wall under the upper bench for Kiruna Hybrid rooms.

One new field appears on the 2026 notice that was not on the 2025 one. Under "Manufacturer(s)," CPSC names SFactor, of China. That is the first time a federal document has put the contract manufacturer's name to these rooms, and it matches the Chinese supplier cluster in our reporting on the company's import records.

The Weight Limit the First Recall Promised Reached Two Models Out of Five

The October 2025 remedy said owners "will also receive a revised product manual from Sauna360 that includes the weight limit." CPSC never published the figure. It is 250 pounds per seating position, and it appears as a caution in the current manuals: "The benches have been tested to ISO 7173 standard and have a maximum weight limit of 250 pounds per seating position."

That caution is in two manuals. Tylö's owner resources library lists six Halmstad and Kiruna manuals. The Halmstad 2 and Kiruna Hybrid 2 books are both Revision F, dated April 8, 2026, and both carry the 250-pound caution. The manual posted for Halmstad 3 and Halmstad 4 is Revision D, dated April 9, 2025. The manual posted for Kiruna Hybrid 3 is Revision B, dated October 1, 2024. Both predate the October 2025 recall, and neither contains a bench weight limit or an ISO 7173 reference.

Three of the five recalled models, in other words, have no revised manual on the brand's public download page almost eleven months after the recall that promised one. Owners who took the first remedy may have been handed a revised book in person, and nothing public says whether they were.

The same manuals show how the benches are held together. In the Kiruna Hybrid 2 Revision F book, neither bench seat is fastened to anything: both "slide over the top of the left and right bench braces and drop into place," with the load carried by wall-mounted braces. In the Halmstad 2, the upper bench is the same drop-in, and the lower bench is held by two M4 by 50 mm Torx screws driven up from underneath into a brace. A comparison of the Halmstad 2 manual from Revision C in October 2024 to Revision F in April 2026, a span covering the entire first recall, shows no change to any fastener size, count or type. What changed was the addition of the 250-pound caution and two assembly steps, one securing the lower bench to the wall and one anchoring the bench leg to the floor with two 2-inch pocket screws.

Six months before the first recall, one joint was re-engineered. Revision D of the Halmstad 3 and 4 manual, dated April 9, 2025, replaced two Torx wood screws at the return bench joint with two 5/16-inch by 3-inch hex bolts, nuts, four flat washers and two split-lock washers, and added a warning not to overtighten because "compression will destroy the integrity of wood fibers in the bench support."

Radiant Health Told Its Customers to Stop Six Weeks Before the CPSC Notice

The infrared recall did not appear from nowhere on September 17. Radiant Health, a brand supplied by Sauna360, has been posting to a safety notice page since summer. Its dated entries run August 7, 2026, "A Stop Use notice has been issued," then August 27, an update from the company's chief executive, then September 11, "An update on the CPSC's schedule," then the recall itself.

Radiant Health's page carries operational detail the federal notice does not. It names National Service Alliance as the service provider coordinating appointments. It puts the repair at typically under an hour per unit. It says new sauna deliveries are paused while the safety enhancement is built into production, with roughly six to eight week delivery once shipping resumes. It confirms the recall applies to saunas in commercial and shared settings, including spas, gyms, studios and rentals, and to second-hand owners, because the remedy follows the product rather than the buyer.

It also carries a warning worth passing to any customer trying to check a unit: "the model numbers listed in the recall notice may not match the model number provided for your sauna." Radiant Health defines its own scope as every Elite and Pause infrared sauna shipped before August 1, 2026, whatever the model string says.

Sauna360's own recall index describes the infrared action as a "Shipment Pause and Voluntary Recall of Installed/Delivered Saunas."

Canada Has a Parallel Notice and a Different Sales Window

Health Canada published alert RA-82120 on the same day, covering the infrared panels. It reports 6,758 units sold in Canada against 41,580 in the United States, and five incidents in Canada with no injuries.

Two details differ from the American notice. Health Canada gives the sales period as January 2013 to August 2026, where CPSC gives May 2013 through July 2026. And Health Canada names a brand CPSC leaves out: Polar. The bench recall has no Canadian counterpart. Searches of the Canadian, EU, UK, Australian and New Zealand recall registers turn up no bench-collapse notice in any of them.

What Is Not in the Record

Several things a dealer would want are absent from every public source as of September 18.

There is no published dealer guidance. Both Sauna360 FAQ documents, dated September 17, run to 20 questions apiece and use the words "installer" and "technician" without once addressing dealers, distributors, retailers, floor models or showroom inventory. CPSC's own recall guidance expects a recalling firm to tell retailers to stop selling and to instruct them on handling stock, and federal law prohibits selling a product subject to a publicized voluntary corrective action.

There is no repair timeline. Both FAQs answer the parts question the same way: "Currently, we are unable to provide an exact timeline." Owners are told to stop using a $6,000 to $13,000 appliance with no date attached.

There is no completion figure for the first recall. Neither CPSC nor Sauna360 has said how many of the roughly 1,000 rooms recalled in October 2025 actually received the retrofit.

There is nothing in Masco's filings. The parent company's FY2025 annual report and both 2026 quarterly reports carry only standing product-safety language, with no mention of the sauna recalls and no quantified charge. Masco still lists Sauna360, Inc. among its subsidiaries, and no 2026 filing classifies the business as held for sale or discontinued.

And there is no litigation on the public docket. A search of federal court records returns no personal-injury or class-action case naming Sauna360, though plaintiff firms have begun posting pages soliciting bench-injury clients.

What Owners and Operators Should Do

Stop using the sauna. That applies to traditional Halmstad and Kiruna Hybrid rooms on the bench recall, to any infrared or hybrid room on the panel recall, and to anyone who already had the 2025 bench repair done.

Register at sauna360.com/product-recall, by phone at 866-936-5962 between 8 a.m. and 5 p.m. ET, or at recall@sauna360.com. Registration wants the name, current address, phone, email, model and serial number. If the sauna has moved or changed hands, the company asks for the current location, because the technician has to come to it.

Note the contact has changed. The October 2025 notice gave 888-780-4427 on Central time and a technical support mailbox. Anyone working from the old notice, which is still live on the CPSC site with its original remedy and phone number and no banner pointing to the expansion, will reach the wrong queue.

Commercial operators are covered. A room in a gym, spa, studio or short-term rental falls under the same recall as one in a basement, and the remedy is free either way.
