If your tub has no tile lip, that is by design. Ella walk-in tubs have a flat deck edge, and the water barrier at the wall is a glue up tile flange added at installation. The manual calls for a rustproof, waterproof strip about 5 inches tall, glued to the tub edge with 100 percent silicone so it overlaps the edge by about 2 inches, with the tile or wall panels overlapping the flange and the deck and every joint siliconed. The current Ella part that fills that role is the flexible, reversible glue up flange kit described in the glue up tile flange kit guide, so check which length your wall run needs before the walls are finished.
Likely Causes
- The installer expected a molded flange like a standard bathtub and did not plan for the strip.
- The manual on hand describes a generic aftermarket strip rather than the current flexible kit.
- The walls were started before the flange went on.
What to Check, in Order
- Level the tub with every leg bearing on the floor and complete the water test before finishing any wall.
- Measure the total run of tub edge that meets a wall, back plus each end, at deck height, and match it to the kit lengths in the flange kit guide.
- Clean the tub edge with the alcohol tissues in the kit, then bond the flange with 100 percent silicone so it overlaps the tub edge. The strip is reversible, and which colored side faces out depends on whether the fixture already has an integral flange.
- Run the tile or wall panel down over the flange and onto the deck, then silicone every joint, including where the extension panel meets the tub and where the end panel meets the wall. Full detail is in tile flange, caulking and wall finishing.
- Existing wall tile that is sound and properly sealed can stay; your installer confirms its condition.
- For a shower base, the same flange approach applies, and the flexible strip can go on after the base is set. See shower base and dam installation.
- More install day answers are in installation common questions.
When to Open a Ticket
If you are unsure which flange length fits, or the walls are already partly finished, open a ticket at ellasbubbles.com/support with your model, a sketch of the alcove with wall lengths in inches and a photo of the tub edge at the wall. Your Ella dealer or the team at (800) 480-6850 will confirm the kit and how to place it.
