A level, correctly installed Ella walk-in tub does not leak. The door is pulled tight against its seal by a latch mechanism, and when water does reach the floor the cause is almost always correctable: a leg that is not carrying weight, a hand shower mounted on the wall without the leak kit, or a worn latch piece. Leveling comes before every other adjustment, as How Do I Fix a Walk-In Tub That Is Not Level? explains.

How the Door Seals

The first video on this page shows Ella's outward-swing doors. They use a gear and shaft locking mechanism that pulls the door evenly into a tight, leak-proof seal. The U-shaped door has a three shaft gear and lock system, and the extra wide L-shaped door has a two shaft gear and lock system. Both handles are easy to engage and disengage. When you close the door and turn the handle, it should pull evenly into the seal all the way around.

The door is designed to carry its own weight and nothing more. The door and seal warranty is valid only when the tub and door are aligned correctly and the alignment has not been changed by a bather's weight on the door, so never lean, sit or step on the open door.

Level First, Every Time

Ella tubs have at least six leveling legs, and each one must rest solidly on the floor with no gap beneath it. When a leg hangs free the shell bows, the door rubs the jamb and the gasket may not touch on the lower handle side, which is where most door leaks begin. The fix is at the legs, never at the hinges.

  • Check every leg. Any foot with a gap beneath it is the cause.
  • If the tub is bowed down in the center, extend the center leg until the door frame clears the swing of the door.
  • Measure all sides and keep adjusting until the tub is level and straight.
  • Open and close the door several times. It should close securely and pull evenly into the seal.
  • If the seal is still not compressed enough on the latch side, the team may suggest a shim at the door latch.

Clean the seal with rubbing alcohol and reshape it by hand if shipping flattened it, then fill to the seat and watch for 20 minutes. Leveling is part of installation, so it belongs to your local licensed plumber or installer. Ella does not send technicians.

Leaks That Are Not the Door Seal

Water under or behind the tub often has nothing to do with the door.

  • Hand shower on the wall. Lifting the pull-out hand shower to a wall mount without the leak kit lets water drip through the deck insert hole to the space behind the tub. What Is a Barrel Extension Hose (Leak Elimination Kit) on a Walk-In Tub? explains the 5 foot extension hose and stainless steel barrel that plug that hole.
  • Push control button. The second video shows the leak prevention step for a push control: remove the collar and button, place a thin bead of silicone caulk around the rubber gasket, smooth it, snap the collar back on and clean the area with denatured alcohol.
  • Cracked latch. If the white plastic latch receiver or its silicone cover cracks, the handle can no longer pull the door tight. That calls for a replacement latch assembly, not a new door, and gluing it is not a lasting repair. See Why Did the Plastic Door Latch Crack and Why Won't the Door Seal Now?.
  • Spray over the top. A walk-in tub is open on top, so a hand shower aimed at the room or jets running above the waterline send water onto the floor. A 4 fold glass screen with its gasket brushing the deck keeps that water in, as Why Does Water Spray Out of the Tub When I Use the Hand Shower? describes.

Common Questions

Do walk-in tub doors start leaking over time?
A door that stays level, aligned and free of a bather's weight keeps sealing. When a leak does appear after years of use, it is usually a latch receiver or silicone cover that has worn, and that is fixed with a replacement latch assembly rather than a new door.
Should I adjust the hinges if my door leaks?
No. A door that rubs or leaks is fixed at the leveling legs, and adjusting hinges does not correct a twisted shell. A door that visibly droops or tilts when open points to a bent hinge, which is a replacement part rather than an adjustment.
Why is there water behind my tub near the hand shower?
That is the classic sign a pull-out hand shower was wall-mounted without the barrel extension hose. Water runs down the hose into the deck base and through the deck hole. Fitting the leak elimination kit plugs the hole and avoids a service call.
Can a door leak on a clearance tub be fixed?
A unit sold as a Handyman Special was disclosed with a door leak that is a manufacturing defect and cannot be repaired or covered; it suits shower style use. Any other clearance tub is fully working, and a door leak on one is a normal leveling and seal check.
Who fixes a leak, and does Ella send someone out?
Ella does not send technicians. Replacement parts such as a latch assembly or seal ship under the warranty, and a local licensed plumber or installer does the labor. Open a ticket at ellasbubbles.com/support with your model, serial number and photos, or call (800) 480-6850.
