A UL, ETL or CSA mark on a walk-in tub tells an inspector, an electrician or an owner that the equipment was evaluated against a published safety standard by an independent laboratory. Ella walk-in tubs are built to conform to UL Standard 1795 for hydromassage bathtubs and CSA Standard C22.2 No. 218.2, and the pumps, in-line heaters and other electrical components inside the tub are ETL certified and clearly marked. The label carrying the listing information, model and serial number sits inside the access panel on the front apron, on the seat side next to the door. This page explains what the words on that label mean, who the laboratories are, and what the marks do and do not cover.
Listed, Certified, Conforms: What Each Word Means
| Word | What it means | Where it appears in Ella documents |
|---|---|---|
| Listed | A laboratory evaluated the product against a named standard and authorized its mark, and the product can be looked up in the laboratory's public directory. | The team calls the tub label the UL label, and Ella tubs can be looked up on the UL website. |
| Certified | The same idea as used by Intertek (ETL) and CSA Group: a certified component carries the mark and can be traced in the directory. | Pumps, in-line heaters and electrical components are ETL certified; the HoistAssist sheet lists cETL from Intertek. |
| Conforms to | The product was designed and built to meet a named standard. This is the wording Ella uses for the whole tub. | "Conforms to UL STD 1795 Hydro Massage Tub and CSA STD C22.2 No. 218.2." |
The full support answer, including a note on the LayDown 32x72, is in safety certifications on Ella tubs.
Who the Testing Laboratories Are
UL, Intertek and CSA Group are independent laboratories that publish or adopt safety standards and test products against them. In the United States, OSHA recognizes qualifying laboratories as Nationally Recognized Testing Laboratories, and UL and Intertek both appear on that list, which is why an inspector accepts a UL or ETL mark as evidence of third-party testing. The official program page is OSHA Nationally Recognized Testing Laboratory Program.
- UL publishes UL 1795, the standard for hydromassage bathtubs, and runs the directory where Ella tubs can be looked up.
- Intertek applies the ETL mark to products tested to published standards; the small "c" in cETL shows evaluation to the Canadian requirement.
- CSA Group publishes the Canadian standards, including C22.2 No. 218.2 for the tub, B125.1 for faucets and B45.5 for plumbing fixtures.
Anatomy of the Label
The label inside your tub carries the listing information along with the model and the serial number, which typically begins with the letter M. Here is how to read it and the component marks in the equipment bay.
| Element | How to read it |
|---|---|
| The mark | The laboratory's logo: UL, ETL or CSA. It identifies who did the testing. |
| Small "c" and "us" letters | "c" means evaluated to the Canadian standard and "us" to the United States standard; both together means accepted in both countries. The HoistAssist sheet prints cETL and cUPC. |
| Standard number | The standard the product was tested against, such as UL 1795 or CSA C22.2 No. 218.2 for the tub, or a plumbing standard such as CSA B125.1 for a faucet. |
| Model | Identifies the product; the same model name is on your invoice or order confirmation. |
| Serial number | Identifies your individual tub and tells the team when it was made and which parts fit. |
To reach it, pull the magnetic access panel next to the door gently away from the frame from one corner and look on the inside of that panel; on some tubs the labels are mounted inside the large panel on the seat side of the front apron. Photograph the whole label. Both spots are shown in where to find your model and serial numbers, and the label itself is described in what the serial number label is.
The Standards Named in Ella Documents
| Product | Standards and marks printed | Source |
|---|---|---|
| Ella walk-in tubs | Conforms to UL 1795 and CSA C22.2 No. 218.2; pumps, in-line heaters and electrical components ETL certified | Live certifications page and the electrical installation video |
| Ella 2-piece fast-fill faucet | Certified to CSA B125.1, ASME A112.18.1 and ICC 117.1; ANSI/NSF 61/9; ADA lever handle; IAPMO R&T UPC | Faucet section of the spec sheets, for example the Zen 30x52 sheet |
| HoistAssist (Transfer3060HL) | cETL (Intertek); cUPC and USPC (IAPMO); ANSI Z124.1.2 for plastic bathtubs; ASME A112.19.7 for whirlpool appliances; ASME A112.19.15 for walk-in bathtubs; CSA B45.5 for Canadian plumbing fixtures | HoistAssist spec sheet |
A faucet from another manufacturer paired with an Ella tub carries that manufacturer's own markings and warranty. The HoistAssist is described in HoistAssist and the CareGiver assisted-bathing line.
What a Listing Does Not Cover
A listing describes the equipment as it left the factory. It does not describe your bathroom, wiring or plumbing, and it never replaces a licensed electrician or your local code.
- Every jetted Ella tub needs its own dedicated GFCI protected circuit that no other appliance shares, with the breaker sized for the package installed; see electrical requirements by model.
- The drain, supply lines and shut-off valves are installed to your local plumbing code by your plumber.
- Whether a specific installation passes is decided by your local inspector. Ella can say what the tub conforms to and where the label is; the inspector and your installer decide the rest.
Share this video with an electrician who asks about listings: it shows that the components are ETL certified and labeled at the factory, then covers the dedicated GFCI outlets and correctly sized GFCI breakers the installation needs.
For Canada: CETL, CUPC and the CSA Standards
For a Canadian inspector, the line to give is that the tub conforms to CSA Standard C22.2 No. 218.2. On component and accessory marks, the small "c" beside ETL or UPC shows evaluation to the Canadian requirement. Ella faucets list CSA B125.1, and the HoistAssist adds CSA B45.5. Ella tubs are built for North American 120 volt, 60 Hz electrical service on dedicated GFCI protected circuits; if your project uses a different standard, discuss the electrical plan with your Ella dealer or the team at (800) 480-6850 before ordering. Canadian projects are covered in ordering from Canada, Alaska, Hawaii or internationally.
What to Have Ready for an Inspection
- ☐ A clear photo of the whole label, showing listing information, model and serial number
- ☐ The conformance line: UL Standard 1795 and CSA Standard C22.2 No. 218.2
- ☐ A note that the pumps, in-line heater and electrical components are ETL certified and marked
- ☐ The faucet specification page if the plumbing inspector asks about the faucet
- ☐ The number of dedicated GFCI circuits your package requires
Ella does not routinely mail or fax a separate certificate, because the certification is printed on the tub and the tubs can be looked up on the UL website. One model to confirm before you pull a permit: the LayDown 32x72 has no published listing statement, so ask the team for its current listing status in writing before the inspection. If your permit office asks for more than a photo of the label, tell the team at (800) 480-6850 or through ellasbubbles.com/support exactly what is requested and they will tell you what can be supplied for your model.
