Caring for your walk-in tub door seal so it stays watertight for years

Updated September 2026

Walk-in tub door seal care comes down to two easy habits: keep the seal and door frame clean, and leave the door slightly open whenever the tub is not in use. Your door seal is designed to stay watertight for many years, and residue buildup and constant compression are the two things that shorten its life. Both are fully in your control.

Watch: Proper Door Seal Maintenance

The video shows the routine for both door styles: clean the seal and door frame regularly with a common household cleaner, wipe the gasket and inner frame on inward doors, re-secure a loose seal with a thin bead of silicone in the gasket channel, and leave the door slightly open between baths so the gasket is never compressed for days at a time.

Routine Seal Care

  1. Clean the seal itself on a regular basis with a common household cleaner, keeping it free from any debris. Rubbing alcohol also works well for cleaning the silicone seal.
  2. Clean the door frame regularly too. Any residue that is allowed to build up, or debris left in the seal or frame, can lead to door leaks. One owner traced a recurring leak to grit on the seal and found that a quick wipe before each bath stopped it entirely.
  3. On inward swing doors, wipe down the gasket and the inner frame the same way, on a regular basis.
  4. Leave the door slightly open when the tub is not in use. This prevents unnecessary compression of the gasket and extends its flexibility and life.

If Your Tub Just Arrived and the Seal Looks Deformed

During shipping, the silicone seal can stick or take a temporary set. This is easy to restore: gently squeeze the seal with your fingertips and pull it away from the door frame to bring back its shape, then clean it with rubbing alcohol. Once installed, the door should close smoothly into a watertight seal. Our delivery day article covers the rest of the unpacking checks.

If a Seal Becomes Loose

In the rare instance that a door seal becomes loose or damaged, it can be re secured or replaced. The video above demonstrates the process:

  1. Place a thin bead of silicone into the gasket channel.
  2. Allow the silicone to set up for 20 minutes before reinserting the gasket.
  3. Wait 24 hours for the silicone to dry before using the tub.
  4. On inward swing doors, 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, then wait 24 hours to dry.

Replacement seals are available through our support team. Have your serial number handy, it is on the label behind the magnetic access panel next to the door; see finding your model and serial number.

Installing a Replacement Seal

When a new gasket arrives, this video shows how it goes in: spray adhesive remover on the gasket so it slides into the door channel and press it into the groove with a spatula until it is fully seated. At outer curves, use diagonal cutters to make four V-shaped relief cuts where the gasket bends, keeping the cuts above the gasket reach line; at inner curves make straight vertical cuts. Continue applying remover and guiding the gasket to the end, then make a small angled cut so the tip slightly overlaps yet sits fully in the groove. Full replacement guidance, including the LayDown glass door, is in door seal care and replacement and the LayDown door seal installation video.

The Bigger Picture: Why Doors Leak

A clean, healthy seal does its job only when the tub is level. The number one cause of door leaks is leveling, not the seal. All leveling legs must touch the floor with equal weight, with no gap under any leg, so the frame and shell stay true and the door closes smoothly into a watertight seal. If a door begins to leak and cleaning the seal and frame does not resolve it, leveling is the first thing to have checked, using our leveling guide. Also remember that the door is designed to hold its own weight only, so please do not lean or press body weight on the open door; water at the door: what to check walks through the full diagnosis.

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. A door that stays latched keeps the silicone gasket compressed for days at a time, which shortens its flexibility and life. Leaving it ajar between baths is the standing recommendation for every Ella tub, and it costs nothing.
Is there a lubricant or spray I should put on the seal?
The published care instructions call for cleaning only, using a common household cleaner or rubbing alcohol, and no lubricant or spray is recommended for the seal. If your seal feels sticky or the door is hard to close, clean the seal and the door frame first, since residue buildup is the usual cause. If that does not resolve it, open a ticket at ellasbubbles.com/support with your model and a photo, and the team will advise.
What do I clean the gasket with so I do not damage it?
A common household cleaner or rubbing alcohol on a soft cloth is all the gasket needs. Skip abrasive pads and harsh chemicals, which can damage the silicone. Clean the door frame at the same time, because residue or debris left in either place can lead to door leaks.
The seal is clean but the door still leaks. What next?
Check leveling next, because the number one cause of door leaks is leveling rather than the seal. Every leveling leg must touch the floor with equal weight, with no gap under any leg, so the frame and shell stay true and the door closes smoothly with even gaps into a watertight seal. Our leveling guide linked above walks through the check, and remember never to lean or press body weight on the open door, since that changes its alignment.
How do I get a replacement seal?
Open a ticket at ellasbubbles.com/support with your serial number and a photo of the seal, and the team will identify and send the correct gasket for your door family. The serial number is on the label behind the magnetic access panel next to the door. Seals are covered under the parts warranty for the original owner when the tub and door have been aligned correctly.
Is the door seal covered by the warranty?
Yes. The door and door seal carry the Lifetime Limited Warranty for the original owner, valid when the tub and door have been aligned correctly and the alignment has not been changed by putting body weight on the door. Keeping the seal clean and leaving the door slightly open between baths are the simple habits that keep it in good condition. See warranty coverage for the full terms.
How long does silicone need before I can use the tub?
Allow the bead of silicone to set for 20 minutes before reinserting the gasket into the channel, so the bead has time to grab. Then wait a full 24 hours for the silicone to cure before filling or using the tub. Rushing either step can leave you with a bond that is not watertight.
My new tub's seal looks flattened or stuck. Is it defective?
Almost never. During shipping the silicone seal can stick or take a temporary set, and that is easy to restore. Gently squeeze the seal with your fingertips and pull it away from the door frame to bring back its shape, clean it with rubbing alcohol, and leave the door open for a while so it recovers. Once installed, the door should close smoothly into a watertight seal.
