If you have just moved into a home with an Ella's Bubbles walk-in tub already installed, welcome. As a second owner you can identify the model from the serial label and the shape of the door, download the right manual from the product page, and reach the same lifetime technical support and replacement parts that every Ella owner enjoys. The Lifetime Limited Warranty itself belongs to the first purchaser at the original installation address and does not transfer, but that does not leave you on your own. This guide covers what to find, what to check and who to call in your first week.
Step 1: Find the Serial Number

The video shows where the label lives. Your tub's serial number is on the label behind the magnetic access panel next to the door. Pull that panel gently away from the frame, no tools needed, and photograph the label. The serial number tells the team when the tub was made, who built it and which replacement parts are compatible, so it is the single most useful thing a second owner can have ready. Serial numbers typically begin with the letter M. Watch: Ella's Bubbles: Serial Number Location with a full transcript.
Step 2: Identify the Door Family and Model
Ella tubs are grouped by door style, and the door is usually the fastest way to narrow down the model before the serial number confirms it:
- Inward-swing acrylic door on models such as the Standard, Zen and Flow.
- Inward-swing stainless steel door on the Elite, Ultimate, Deluxe, Royal and Petite, and an aluminum-framed frosted glass inward-swing door on the Ultra.
- Outward-swing U-shape door on the Capri, Monaco, Lounger, Mobile, Front Entry, ShaK and Big4One.
- L-shape outward-swing transfer door on the wheelchair Transfer family.
If you are still unsure, send two or three photos of the tub, the door and the serial label on a ticket and the team will identify the model for you. Our guide to identifying the brand and model from labels, doors and faucets goes deeper, including how to tell whether the tub is an Ella at all.
Step 3: Download the Manual
Every product page on ellasbubbles.com has a Downloads section with the spec sheet, the owner's manual, operating and cleaning instructions and the warranty form. Manuals are written per door family rather than per individual model, so the outward-swing manual covers the Capri, Monaco and Lounger, and the stainless-steel door manual covers the Elite, Ultimate, Deluxe, Royal and Petite. If the previous owner left paperwork behind, keep it, but be aware that older printed manuals may show an earlier warranty text. Find your manual, spec sheet and drawings by model lists which document belongs to which tub.
Step 4: Understand Your Warranty Position
The published warranty is extended to the first purchaser only, is nontransferable, and applies to the original owner at the original installation address. When ownership changes, the warranty is void. What continues for every Ella tub is lifetime technical support by phone, email and video, and access to replacement parts for the tub, including door seals. If you are considering moving the tub to another home, please read warranty transfer and ownership first.
Step 5: Run a First-Week Checklist
- Look at the door seal. Wipe it with rubbing alcohol to remove any residue, and check that it is seated evenly with no deformation. If it is stuck or misshapen, squeeze the seal gently with your fingertips and pull it away from the door frame to restore its shape.
- Leave the door open when the tub is not in use. This is the single best habit for a long seal life.
- Confirm the electrical. Ella tubs are installed on a dedicated GFCI-protected circuit. If you cannot tell whether the tub has one, an electrician can confirm it quickly.
- Check both drain stoppers. Each drain must close completely and the locking nut must be tightened on both stoppers, otherwise the tub can lose water during a bath. Do not fill above the center of the drain handle.
- Do a 20-minute water test. Fill the tub, wait 20 minutes and confirm the door seal is watertight before you rely on it.
- Flush the jets. Mix 2 cups of white vinegar with 2 cups of water, fill the tub to one inch above the highest jets, add the mixture, run the tub for 10 minutes, then drain. This is the same flush recommended once a month.
- Operate every control once. Hot and cold, both diverters, the hand shower on every setting, the hydro and air pumps, and the chromatherapy light. Fill the tub above every jet before switching a pump on. A light humming noise when nothing seems on is the ozone sanitizer and is normal, and the air system's automatic purge about 20 minutes after a bath is normal too.

The seal is the part a second owner most often inherits in unknown condition, and this video covers its care. Clean the seal and door frame regularly with a common household cleaner, since residue or debris in the seal or frame causes leaks. If a seal is loose or damaged it can be replaced and secured with a thin bead of silicone in the gasket channel, allowed to set before the gasket is reinserted and left 24 hours to dry. And leave the door slightly open when the tub is not in use so the gasket is not compressed. Full details are in caring for your door seal.
