The door seal on a walk-in tub, also called the door gasket, is the soft silicone strip around the door opening. When you close and lock the door, the gasket compresses against the frame into a watertight seal. It needs two things: a clean surface to press against, and a rest when the tub is idle, so leave the door open or unlocked whenever the tub is not in use.

How It Works

The seal works together with door alignment and tub leveling. On a level tub the latch draws the door evenly into the frame and the silicone compresses the same amount all the way around. Inward-swing doors get extra help from the water, which presses the door into the seal as the tub fills and is why the door will not open until the tub has drained.

New seals sometimes arrive stuck or slightly flattened from shipping. That is normal: squeeze the seal with your fingertips and pull it away from the door frame to restore its shape, then wipe it with rubbing alcohol. Your installer confirms a watertight seal after a 20 minute fill as part of the warranty activation checklist.

Which Ella Models Have It

Every Ella walk-in tub door, inward-swing or outward-swing, closes against a silicone gasket. Each door uses its own seal size, so a replacement is matched to your model and serial number. Not sure which door you have? Start with Which door does my tub have?

What to Know as an Owner

Keep the door open or unlocked between baths and clean the seal with a soft cloth and rubbing alcohol, never abrasives. Never lean on the door or use it as a handhold; the warranty on the door and seal depends on the alignment staying as it was set at installation and not being changed by a bather's weight on the door.

If you see water at the door, do not assume the seal has failed. The number one cause of a door leak is leveling, not the gasket: a leg that has lost contact with the floor lets the frame warp, and the door no longer meets the seal evenly. Work through Water at the door: what to check first, then see Caring for your door seal for reseating and cleaning steps.

The door seal is covered by the Lifetime Limited Warranty and has no scheduled replacement interval. When a replacement is warranted, the team ships one after a support ticket with your serial number and clear photos of the seal and the leak point. Have those ready, note whether all leveling legs touch the floor, and open a ticket at ellasbubbles.com/support or call (800) 480-6850. There is more in Common questions about door seals.
