Spa Hot Stone & Wax Warmer Temperature Verification Checklist [FREE PDF]

Improper temperature management of hot stones and wax warmers is one of the leading causes of client burn injuries in spa settings, making rigorous thermal verification a critical safety and liability priority. State health department spa regulations in most jurisdictions require that heating appliances used in treatments maintain documented temperature logs and fall within safe therapeutic ranges, typically 110–145°F for hot stones and 95–115°F for wax. The CPSC has issued guidance on burn risk

Hot Stone Warmer Unit Inspection

Inspect the hot stone roaster or warmer unit for condition, electrical safety, and proper setup before use.

Is the hot stone warmer unit clean, free of mineral deposits, and in good physical condition?
Is the power cord and plug of the stone warmer free of fraying, damage, or burn marks?
Is the warmer plugged into a GFCI-protected outlet appropriate for wet-area appliances?
Is the water level in the stone warmer at the correct operating level per manufacturer specifications?
Has the stone warmer been allowed the manufacturer-recommended warm-up time before temperature verification?
Please photograph the warmer unit showing its current condition and setup.

Hot Stone Temperature Measurement

Record actual temperature readings of stones before client application to ensure they fall within safe therapeutic ranges.

What is the recorded water temperature inside the stone warmer?
What is the surface temperature of the largest stones measured with a calibrated thermometer?
What is the surface temperature of smaller facial or detail stones?
Are all stone temperatures within the facility's approved therapeutic safe range?
If any stones are outside the approved range, have they been removed from service and logged?

Hot Stone Condition & Sanitation

Verify that stones are clean, sanitized, and free of cracks or damage that could affect treatment safety.

Have all stones been cleaned and sanitized per facility protocol between client uses?
Are all stones free of cracks, chips, or rough edges that could cause client injury?
Are stones of the appropriate basalt or approved material type for thermal retention?
Have any damaged or cracked stones been removed from inventory and documented?
Please photograph any stones removed from service due to damage or condition.

Wax Warmer Unit Inspection

Inspect wax warmer appliances for safe electrical condition, cleanliness, and correct operational setup.

Is the wax warmer unit clean and free of wax overflow, buildup, or contamination on exterior surfaces?
Is the wax warmer power cord and thermostat control free of damage, discoloration, or burn marks?
Is the wax warmer positioned on a stable, heat-resistant surface away from flammable materials?
Is fresh, uncontaminated wax loaded in the warmer for this session?
Is the wax type loaded in the warmer correct and appropriate for the treatments scheduled?

Wax Temperature Measurement & Verification

Record actual wax temperature readings to confirm they are within safe application ranges before client use.

What is the current wax temperature reading from the warmer's built-in thermometer or display?
What is the independently verified wax temperature using a calibrated probe or IR thermometer?
Is the variance between the warmer display and the independent thermometer within 5°F or less?
Is the wax consistency (viscosity) visually appropriate for safe application at the measured temperature?
Has a wrist test or glove test been performed to verify safe application temperature before first client?

Client Burn Prevention Protocols

Verify that therapist knowledge, communication protocols, and emergency procedures are in place to prevent and respond to burn incidents.

Are all therapists trained in burn recognition and first-aid response for thermal spa injuries?
Is a burn first-aid kit stocked and accessible in or adjacent to the treatment room?
Are clients screened for heat sensitivity, diabetes, or neuropathy before hot stone or wax treatments?
Are written client consent forms that include burn risk disclosure on file for all thermal treatment clients?
Is there a documented incident reporting procedure for thermal burns posted or accessible to staff?

Electrical Safety & Appliance Compliance

Confirm that all heating appliances meet electrical safety standards and are used within their rated specifications.

Are all hot stone and wax warmer appliances UL-listed or certified by a recognized testing laboratory?
Are heating appliances used only within their manufacturer-rated voltage and amperage specifications?
Are heating appliances switched off and unplugged when not actively in supervised use?
Is there adequate electrical circuit capacity to power all heating appliances simultaneously without tripping breakers?
Are extension cords absent from use with any heating appliances in the treatment room?

Temperature Log Documentation & Sign-Off

Complete required documentation of all temperature readings and inspection findings for regulatory and liability records.

Have all temperature readings from this inspection been recorded in the facility's equipment temperature log?
Were any temperature readings out of acceptable range during this inspection?
If out-of-range temperatures were found, have the affected appliances been removed from service pending correction?
Please describe any corrective actions taken, equipment issues noted, or maintenance requests submitted.
Has this completed inspection record been submitted to the Spa Director or designated supervisor?
