January 21, 2026 – A serious incident involving an Enlighten Sauna Sapphire 5 model has brought critical safety concerns to light, detailing a malfunction where the sauna’s heating elements remained active and overheated despite being turned off, leading to extensive internal damage and a significant fire risk. The incident report highlights concerns regarding the product’s safety certifications and the manufacturer’s response.
Product Details
Incident Overview
In June 2025, a consumer reported a dangerous malfunction with their Enlighten Sauna Sapphire 5, purchased from enlightensauna.com. Despite the sauna being turned off with all lights extinguished, the internal coils inexplicably remained hot and continued to escalate in temperature throughout the night.
The following morning, the owner discovered alarming conditions within the sauna: black residue coated the walls, and all interior plastic fixtures had melted due to extreme heat, which registered “off the thermometer.” With no apparent way to shut down the malfunctioning unit, the owner was forced to cut power by turning off the fuse at the main electrical panel to stop the overheating.
The consumer contacted Enlighten Sauna regarding the incident, but their warranty claim was reportedly denied. The manufacturer allegedly attributed the malfunction to an “aroma bowl accessory,” which the consumer stated they had never even used. An independent electrician later verified that the malfunction was not related to the aroma bowl but rather to a fault within the thermostat and sensors. Following the consumer’s report to a [REDACTED] agency, the manufacturer reportedly failed to respond to the agency’s inquiries.
Further investigation by the consumer involved a second sauna company, [REDACTED], which declined to repair the unit. Their representative identified the heater as “foreign, off-brand, and not made for a US market/not ‘UL listed,'” expressing concern that the lack of a fail-safe mechanism allowed the heater to remain on all night, posing a severe fire hazard. The consumer’s subsequent research confirmed that while selling non-UL listed heaters isn’t strictly federally banned, installation often violates local electrical codes (NEC) and could void home insurance due to non-compliance with critical safety standards like UL 875, leading to significant fire and shock risks.
Crucially, the consumer stated that Enlighten Sauna never disclosed that the heater was not made for the US market or that it lacked essential safety features like a fail-safe. This critical information was only discovered after the near-fire incident and was not disclosed by the manufacturer even when the incident was reported to them.
Safety Concerns
This incident with the Enlighten Sauna Sapphire 5 highlights several severe safety concerns:
- Immediate Fire Hazard: The most critical risk is the potential for a catastrophic house fire. A heating element that remains energized and overheats without a functional shut-off or fail-safe mechanism can ignite combustible materials within the sauna and surrounding property, putting lives and homes at extreme risk.
- Electrical Shock Hazard: Malfunctioning electrical components, especially in high-power appliances, can also pose a significant risk of electrical shock to users attempting to troubleshoot or interact with the unit.
- Property Damage: The reported melting of internal plastic fixtures and blackening of walls indicates significant property damage to the sauna itself. Had the incident progressed, it could have led to extensive damage to the consumer’s home.
- Lack of Safety Certifications (UL/ETL): The revelation that the heater may not be UL or ETL listed for the US market is a grave concern. These certifications ensure products meet rigorous safety standards for electrical operation, fire prevention, and overall integrity. Products without such listings lack independent verification of safety and are inherently riskier.
- Absence of Fail-Safe Mechanisms: The statement from the repair company that the heater likely lacked a “fail-safe” is alarming. Essential safety features are designed to automatically shut down a device in the event of a malfunction, preventing overheating and potential fires.
- Impact on Home Insurance: Using or installing non-UL listed electrical equipment can potentially void home insurance policies, leaving homeowners unprotected in the event of fire or damage caused by the non-compliant product.
- Misleading Information/Lack of Disclosure: Consumers were reportedly not informed about the product’s non-compliance with US market standards or the absence of crucial safety features, leaving them unaware of significant risks.
What Consumers Should Do
Consumers who own an Enlighten Sauna, particularly the Sapphire 5 model or any sauna from Enlighten Sauna, should take the following steps:
- Immediately Discontinue Use: If you own an Enlighten Sauna and have concerns about its safety or suspect a similar malfunction, immediately stop using the product.
- Disconnect Power: To prevent any further risk, disconnect the sauna from its power source, preferably by turning off the dedicated circuit breaker at your main electrical panel.
- Inspect for Damage: Carefully inspect your sauna for any signs of overheating, melting, scorching, or unusual odors. Do not operate the sauna if any such signs are present.
- Verify Safety Certifications: Contact Enlighten Sauna to inquire about the specific safety certifications (e.g., UL, ETL) for your sauna model and its heater. Request documentation of these certifications. If the manufacturer cannot provide this, or if a third-party electrician confirms it is unlisted, consider the unit unsafe.
- Consult a Qualified Electrician: If you have concerns, have a qualified and licensed electrician inspect your sauna and its installation to assess its safety and compliance with local electrical codes.
- Report Incidents:
* Report any malfunctions, overheating, or suspected safety issues with your Enlighten Sauna to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
* If you experience or witness a fire or property damage due to a product malfunction, report it immediately to your local fire department.
- Retain Records: Keep all purchase receipts, warranty information, communication with the manufacturer, and any reports from electricians or repair services.
Manufacturer’s Response
The manufacturer’s response to this incident is currently unknown, beyond the reported denial of the consumer’s warranty claim and alleged failure to respond to [REDACTED] inquiries.
