If your walk-in tub door rubs the frame or jamb as it closes, the most common reason is that the tub has bowed slightly downward in the middle because the leveling legs are not all carrying equal weight. The fix is usually simple: raise the center of the tub by extending the center leveling leg until the door frame opens up and the door swings clear. A rubbing door is worth correcting promptly, because a door that cannot close squarely into its frame can go on to leak.

As our technician explains in the video: a lot of times when the door rubs the jamb, it is because the tub is bowed down. To fix that, you raise the tub up from the center by extending, or stretching, the leveling leg. That makes the tub open up, the door frame opens up, and the door clears the swing and the jamb.

Why Leveling Matters This Much

  1. 0:00 Leveling Feet for Bathtub Stability The video explains how leveling feet are crucial for installing a walk-in tub and ensuring its longevity.
  2. 0:29 More Leveling Feet, More Stability The speaker emphasizes that more leveling feet disperse weight, prevent movement, and lead to a more stable and lasting installation.
  3. 1:16 Ella's Bubbles' Unique Design Ella's Bubbles offers more leveling feet, including center legs, compared to competitors, providing a stronger foundation for the tub.

In this clip an Ella dealer explains why the threaded leveling feet matter: they let the installer level the tub on an uneven floor, and having more feet spreads the weight, reduces subfloor movement and frame twist, and protects the silicone seams. Where other tubs offer four or six corner feet, Ella adds center legs, with the configuration varying by model. That center leg is the one that opens up a pinched door frame.

Ella tubs have at least six leveling legs, and many models have as many as eight, to evenly disperse the weight of the tub, the water, and the bather. It is imperative that each of these legs is solidly on the ground with no gaps. If any leg hangs free or carries less weight than the others, the frame and shell can warp, the door goes out of alignment, and the door may not close securely, which can lead to leaks. Misleveling that causes damage is also outside the warranty, so correct leveling protects your coverage as well as your floor. The tub is leveled at the factory before shipping, and the installer must re-verify it on your floor; our leveling guide covers that installation-day check.

The door should swing into its frame without touching the jamb. If it rubs, the frame has been pinched by a bowed tub.

Step-By-Step Leveling Check

  1. Remove the front apron so you can see the leveling legs.
  2. Check each leg in turn: every foot must rest firmly on the floor with no gap between the floor and the leg.
  3. If the door rubs at the top of its swing, extend the center leg to raise the middle of the tub slightly, which opens the door frame.
  4. Adjust each remaining leg so it sits solidly and shares the weight equally.
  5. Place a level on all sides of the tub and take careful measurements on all sides. Adjust legs as necessary until the tub reads level in every direction.
  6. On the Standard and Zen platform, also confirm the front legs are screwed into the subfloor, as the manual requires for stability.
  7. Test the door: it should swing without rubbing and close smoothly into a watertight seal. Extending or shortening legs is also the correct way to close up any visible gap between the door and its frame.

Confirm the Result

After adjusting, close the door and fill the tub a few inches above the door threshold, let it stand, and check that no water appears at the door. A door that closes smoothly and passes a standing-water check is aligned. If the rub returns, re-check the legs; floors can settle over time, and a seasonal re-check takes only a few minutes. If the tub is level and the door still drags, the next things to look at are the handle tension and the hinge, covered in our lock nut and hinge adjustment guide, and the seal itself, covered in what to check when there is water at the door.

On the Standard and Zen platform the front legs are also screwed into the subfloor, so re-check those fasteners when you re-level.

Two Things Not to Do

  • Please do not force a rubbing door closed; that stresses the hinges and the seal instead of fixing the cause.
  • Please do not lean on the door to make it line up. The door holds its own weight only, and pressing a bather's weight onto it can change the alignment you just corrected.

Common Questions

Why does my tub door rub or scrape the frame?
Your walk-in tub door rubs the frame or jamb as it closes almost always because the tub has bowed slightly downward in the middle. This bowing occurs when one or more leveling legs, typically the center leg, are not carrying equal weight, causing the door frame to sag and pinch the door opening. Extending the center leveling leg will raise the middle of the tub, opening the door frame back up so the door swings clear.
Which leg do I adjust?
If your walk-in tub door rubs at the top of its swing, you should start by extending the center leveling leg to raise the middle of the tub slightly. After adjusting the center leg, confirm that every other leveling leg is solidly on the floor and sharing the load equally, with no gaps between the floor and the leg. Finally, place a level on all sides of the tub and take careful measurements, adjusting legs as necessary until the tub reads level in every direction.
Do I have to remove the apron?
Yes, you must remove the front apron to access the leveling legs on your Ella's Bubbles walk-in tub. The leveling legs are located behind this removable front apron, which is designed as an access panel for service and adjustments. Access panels are a standard part of every installation to allow for maintenance like leveling adjustments.
My contractor says the tub is level, but the door is still hard to shut.
While a level bubble indicates the tub is level, it is not the complete solution for a door that is hard to shut. Every leveling leg must also be bearing weight firmly on the floor with no gaps, as an unweighted leg can cause the tub frame to warp. If the door still drags after re-checking each foot and ensuring all legs are solidly on the ground, you should then look at the door handle tension and the hinge, which are covered in our Adjusting the Door Handle Lock Nut, and Why the Hinges Are Not the Fix for a Door That Is Hard to Close guide.
Does an unlevel tub affect the warranty?
Yes, an unlevel tub can affect your warranty coverage. Misleveling is the leading cause of door leaks in walk-in tubs and is specifically excluded from warranty coverage. Therefore, performing a careful leveling check and ensuring all leveling legs are solidly on the ground protects both the door's alignment and your warranty coverage.
The tub was fine for years and now the door rubs. Why?
If your walk-in tub door was fine for years and now rubs, it is likely due to floors settling over time. You should re-check all the leveling legs and re-level the tub to correct any bowing that may have occurred. A seasonal re-check of the leveling legs takes only a few minutes and helps keep the door closing squarely and securely.
Are the front legs different on the Standard and Zen?
Yes, the front legs on the Standard and Zen platform walk-in tubs are different from other models. On these specific platforms, the front legs are designed to be screwed into the subfloor for enhanced stability. When you re-level your tub, it is important to confirm that these front fasteners are secure as required by the manual.
Is there a video that shows the adjustment?
Yes, there is a video that demonstrates the adjustment process for a rubbing door. You can watch the "Proper Door Alignment" video at the top of the relevant support page. Additionally, our Every Installation Video in One Place: Delivery, Leveling, Drains, Electrical, Panels, Flange, Faucets and Screens collects all the leveling clips in one convenient location.
