The most common walk-in tub door seal questions have simple answers: the seal on an Ella's Bubbles walk-in tub is a silicone gasket that compresses when the door is locked, it is covered by the Lifetime Limited Warranty, it has no scheduled replacement interval, and it needs only two things from you, a clean surface and a door left slightly open whenever the tub is not in use. Most reports of a "bad seal" turn out to be residue on the gasket, a seal that has been pushed out of its groove, or a leveling leg that is no longer firmly on the floor, and all three are fixable at home.

The Ajar Rule

Leave the door slightly open whenever the tub is idle. It does not need to be wide open, just not fully latched, so the gasket is not under constant compression. A door that is kept closed all the time can weaken the seal over time, and it is one of the first things the team asks about on any leak report.

If the door has been kept shut and has started to leak, leave it open for about a day, or at the very least overnight, so the seal can reform. Then fill the tub again and check the gasket line. Many leaks clear up with this step alone.

Seals Rarely Fail, so Check These First

  1. Clean the seal and the door frame. Wipe the gasket and the frame with rubbing alcohol or a common household cleaner. Soap film, hair or grit sitting between the gasket and the frame is a very common cause of a slow drip.
  2. Reform the seal. If the gasket looks flattened, stuck or deformed, squeeze it gently between your fingertips and pull it slightly away from the door frame to restore its shape. This is the same procedure used when a tub arrives with a seal that was compressed in shipping.
  3. Reseat the seal. If part of the gasket has popped out of its channel, press it back in along its full length. A gasket that keeps working out can be secured with a thin bead of silicone in the channel, as shown in the video below.
  4. Check the leveling legs. Leveling is the number one cause of door leaks. Every leg must sit firmly on the floor with equal weight. A leg that has lifted lets the frame flex enough to open a gap at the gasket. Our article on a door that rubs the frame shows the center-leg adjustment.
  5. Look at the handle. The handle should sit flush to the inside of the tub, and on outward doors it should face away from the hinges when unlocked and toward the hinges when locked. See the door latch and handle guide.

Inspect the full loop of the gasket. A drip in one spot is often caused by grit or a lifted section somewhere else along the loop.

Seal Maintenance on Video

The maintenance video covers both inward and outward doors. Keep the seal free of debris and clean it regularly with a common household cleaner, and clean the door frame just as often, because residue that builds up on either surface leads to leaks. Inspect the full loop of the gasket, not only the spot that drips. If a seal has become loose and needs to be secured, the video shows a thin bead of silicone in the gasket channel, a 20 minute set before the gasket goes back in, and 24 hours of drying time. The full written procedure, including the inward-door variation, lives in caring for your door seal: cleaning, reseating and replacing the gasket. The video closes with the ajar rule: leave the door slightly open when the tub is not in use to extend the flexibility and life of the gasket.

Replacing the Gasket on Video

When a seal really is damaged, this step-by-step video shows the replacement: spray adhesive remover on the new gasket so it slides into the door channel, press it into the groove with a plastic spatula until it is fully seated, make four V-shaped relief cuts with diagonal cutters where the gasket bends around the outer curves (above the gasket reach line), make straight cuts at the inner curves, and finish with a small angled cut at the end so the tip slightly overlaps yet sits fully in the groove. Follow it with a 20-minute fill test and leave the door ajar afterward. The LayDown glass door has its own seal and clip, covered in our LayDown door seal guide.

Silicone the Team Recommends

When a silicone bead is needed, the product the support team names is GE Advanced Silicone 2 Kitchen and Bath, clear. Use a thin bead only, inside the gasket channel, and always allow the full cure time before filling the tub.

On outward doors the gasket is compressed by the latches, so the handle must complete its full rotation for the seal to work.

Common Questions

Should I leave the door open or closed when the tub is not in use?
Leave the door slightly open whenever the tub is not in use. It does not need to be wide open, just not fully latched, so the gasket is not under constant compression, because a door kept closed all the time can weaken the seal over time. If the door has been kept shut and has started to leak, leave it open for about a day, or at least overnight, so the seal can reform before you refill and check the gasket line.
Do door seals wear out and need replacing on a schedule?
No. There is no published replacement interval for the door seal. The seal is covered by the Lifetime Limited Warranty and normally stays watertight for years when it is kept clean and the door is left ajar between baths. Replacement is reserved for a seal that is actually damaged, and the team verifies that with photos before a new one ships.
Is there a larger or thicker seal if mine seems to have shrunk?
There is not. Each door uses one seal size, and there is no larger or thicker door seal to swap in. A gasket that seems too small almost always points to a leveling leg off the floor, a door sitting low, or a seal that needs cleaning and reforming, so work through the checklist above before assuming the seal itself is at fault.
Will an Ella seal fit another brand of tub, or another brand's seal fit an Ella?
Ella's Bubbles supplies door seals for Ella tubs only and cannot guarantee that an Ella seal will fit another manufacturer's door. In the same way, the team cannot promise that a seal from another brand will sit correctly in an Ella channel or compress properly when the door is locked. Please request the matching Ella part with your model and serial number rather than substituting.
If the door leaks, do I need a whole new door?
Almost never. The fix is generally cleaning, reseating, re-leveling, a handle or latch adjustment, or at most a new seal. The team will ask where the leak appears, whether it is in the same spot every time and whether the door is left ajar between baths, so having those answers and a photo ready speeds things up considerably.
Can I glue the gasket in with silicone?
Only as a thin bead inside the gasket channel to hold a seal that keeps working loose. Let the bead set for 20 minutes before the gasket goes back in and allow 24 hours of drying time before filling the tub. Never run silicone over the sealing face of the gasket or the frame, because that stops the seal from compressing properly. The product the team recommends is GE Advanced Silicone 2 Kitchen and Bath, clear.
Is the seal a hollow tube, and how is it held in?
The seal sits in a channel around the door and is held in place by the channel itself, with an optional thin silicone bead in the channel if it works loose. The exact profile differs by door family, and the LayDown glass door uses its own seal and clip. For the profile on your door, send the team a photo with your model and serial number and they will confirm the correct part.
What if I have done all of this and it still leaks?
Open a ticket at ellasbubbles.com/support with photos of the seal showing where it is coming out of the groove or where the water appears, along with your model and serial number. Once a defective seal is verified, a replacement ships to the original customer address as a warranty part. The full leak checklist, including the leveling and handle checks, is in water at the door: what to check first.

For anything specific to your model or serial number, open a ticket at ellasbubbles.com/support or call (800) 480-6850, and please attach photos so the team can help you quickly.
