Door seal or gasket looks worn, loose, or leaks: care, repair, and replacement

Updated September 2026

The walk-in tub door gasket is the flexible silicone seal that makes your door watertight, and it responds very well to simple care. A door gasket that looks worn, loose, or leaks is often just dirty, compressed from shipping, or unseated from its channel, and each of those has a quick fix at home. When a gasket truly is damaged, it is a replaceable part: open a ticket at ellasbubbles.com/support with your serial number and photos, and a replacement seal can be sent, as a warranty parts item when within terms.

Start with the Simple Causes

  • New tub, seal looks deformed: the silicone seal can stick or deform in shipping. Squeeze the seal with your fingertips and pull it gently away from the door frame to restore its shape, then clean it with rubbing alcohol.
  • Debris: any residue or debris left in the seal or in the door frame can cause leaks. Clean both regularly.
  • Leveling: the number one cause of door leaks is a tub that is not level. All leveling legs must touch the floor with equal weight so the door closes smoothly into a watertight seal. Our leveling guide shows how to check every leg.
  • Door kept latched: a door that stays closed all the time keeps the gasket compressed. Leave it ajar for about a day, then fill and check the seal line again; many leaks clear with this step alone.

Routine Seal Maintenance

The maintenance video covers both inward and outward doors. Proper door seal maintenance begins with keeping the seal itself clean and free from any debris:

  1. Clean the seal on a regular basis with a common household cleaner, and clean the door frame regularly as well.
  2. For inward swing doors, wipe down the gasket and the inner frame the same way on a regular basis.
  3. If a seal becomes loose, secure it with a thin bead of silicone placed into the gasket channel. Allow the silicone to set up for 20 minutes before reinserting the gasket, then wait 24 hours for it to dry.
  4. To add silicone on an inward swing door, roll the seal gasket away from the frame and run a bead of silicone down the corner where the gasket meets the frame. You can also add a bead to the other side of the gasket if necessary. Wait 24 hours to dry.
  5. Leave your walk-in tub door open slightly when the tub is not in use. This prevents unnecessary compression of the gasket and extends its flexibility and life.

The silicone the team names for this job is GE Advanced Silicone 2 Kitchen and Bath, clear. Use a thin bead only, and always allow the full cure time before filling the tub.

Replacing the Door Gasket

Replacing an Ella walk-in tub door gasket is easier than it looks. With the right tools and a few well placed cuts you will have a watertight fit. You will need spray adhesive remover, a plastic spatula, and diagonal cutters.

  1. Spray adhesive remover onto the gasket to help it slide more easily into the door channel.
  2. Using the spatula, gently press the gasket into the groove until it is fully seated.
  3. At the curved sections of the door, use the diagonal cutters to make four V-shaped relief cuts on the gasket where it bends around the outer edge. Be sure to make the cuts above the gasket reach line, as shown in the video.
  4. For the inner curves where the door bends inward, make straight vertical cuts instead.
  5. Continue applying adhesive remover and guiding the gasket into place with the spatula until you reach the end.
  6. At the end point, make a small angled cut so that the tip of the gasket slightly overlaps but is fully inserted into the groove.

After the new gasket is in, run the watertight check: fill the tub and let it stand for 20 minutes while you inspect the door edge, which is the same check used at warranty activation. The LayDown glass door uses its own seal and its own short clip; see our seal installation video guide, including the LayDown door.

What to Send When You Need a New Seal

Replacement seals are matched to your door, so the team starts from your tub model and serial number, found on the label behind the magnetic access panel next to the door. Add clear photos of the door and the seal, a note on exactly where the water appears and whether it is the same spot every time, whether you leave the door open between baths, and where the tub was purchased. If the warranty activation form was never submitted, the team may ask you to complete it as part of the request; our article on activating your warranty explains how. Once a defective seal is verified, the replacement ships to the original customer address.

Protecting Your Coverage

The door and door seal warranty remains valid when the door alignment is correct and the seal is not changed by a bather leaning weight on the door, since the door holds its own weight only. If the leak follows the bottom corner of the frame rather than the gasket line, please re-check leveling before replacing any parts. For the full first-check sequence, see water at the door: what to check first.

Common Questions

How do I get a replacement door seal or gasket?
Open a ticket at ellasbubbles.com/support or call (800) 480-6850 with your model and serial number, which are on the label behind the magnetic access panel next to the door. Add clear photos of the door and the seal, a note on exactly where the water appears and whether it is the same spot every time, whether you leave the door open between baths, and where the tub was purchased. The team confirms the correct seal for your door family and ships it, as a warranty part when covered, and once a defective seal is verified the replacement goes to the original customer address.
Is the door seal covered under the warranty?
Yes. The door seal is covered by the Lifetime Limited Warranty as a parts item, and the team verifies the defect from your photos and description before the replacement ships. Coverage depends on the tub and door being aligned correctly and the door never being used to bear a bather's weight, since the door is designed to hold its own weight only. Labor to fit the seal is not covered, but the team provides free technical support, including by live video.
The gasket keeps popping out at the top of the door. Should it be glued in?
Press the gasket back into its channel along the full loop first, since a seal that is unseated in one spot is often lifting elsewhere too. If it keeps working out, a thin bead of GE Advanced Silicone 2 Kitchen and Bath, clear, placed in the gasket channel will hold it: let the bead set up for 20 minutes, reinsert the gasket, and wait 24 hours for it to dry before filling the tub. If it still will not stay, send the team a photo of exactly where it comes out of the groove so they can see whether the seal or the channel is the issue.
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. The team cannot guarantee that an Ella seal will fit another manufacturer's door, or that another brand's seal will sit correctly in an Ella channel, because each seal is matched to a specific door. Please request the matching Ella part with your serial number, and if you are not certain the tub is an Ella, a photo of the door and faucet lets the team confirm it.
Should the door stay open or closed between baths?
Slightly open. Leaving the door latched keeps the gasket compressed all the time, which can weaken it and shorten its life, while leaving it ajar preserves its flexibility. If you have had a leak, leave the door open for about a day and then fill the tub and check the seal line again, since many leaks clear with this step alone.
Is there a lubricant or spray I should put on the seal?
No lubricant or spray is published for the door seal, so please do not apply one on your own. Keep the seal and the door frame clean with a common household cleaner or rubbing alcohol, and leave the door ajar between baths to keep the silicone flexible. If your seal feels sticky or is deformed, squeeze it with your fingertips and pull it gently away from the door frame to restore its shape, and ask the team before applying anything else to it.
Do I need to remove the door to fit a new gasket?
No. Removing the door is not part of the procedure shown in the replacement video; the gasket is worked into the door channel with spray adhesive remover and a plastic spatula, with relief cuts made at the curves using diagonal cutters. If your door type differs from the one in the video, ask the team which clip applies to your door before you start. The LayDown glass door, for example, uses its own seal and its own short clip.
Is there a longer or thicker seal if mine seems too short?
No. Each door uses one seal size, and the replacement is matched to your door from your serial number. A gasket that seems too small usually points to a leveling leg that is off the floor, a door that is sitting low, or a seal that needs cleaning and reforming, so please check those first. If the seal still does not meet the frame after re-leveling, send the team photos of the gap and they will advise.

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. The team is glad to walk you through it, including by live video.
