Which low-threshold walk-in tubs come with a lifetime warranty?

The best low-threshold walk-in tubs with a lifetime warranty are the Ella models whose door lip sits closest to the bathroom floor: the Monaco at 3 5/8 inches, the Mobile at about 3 3/4 inches and the Transfer32 at about 4 to 4.5 inches, with the Big4One and ShaK at about 5 inches. Every Ella walk-in tub carries the same Lifetime Limited Warranty on the shell, frame, door, door seal, finish and supporting equipment, so the warranty does not separate one model from another. Threshold height, seat width and door swing do, in the order laid out in Which walk-in tub features matter most for safety and independence?, and the installation in your home is done by a local licensed plumber and electrician you hire, with Ella supplying the tub, the manuals and the parts.

Threshold Heights, Model by Model

The step-in threshold is the lip you cross at the door, measured from the finished floor. On Ella tubs it runs roughly 3.5 to 7 inches depending on the model and how the drain is set up, against the 18 to 22 inch wall you would swing a leg over on a standard bathtub. The first video on this page shows what that lip means in practice: a low threshold, easy entry, even from a wheelchair, onto a textured slip-resistant floor. The table gathers the published drawing values and team figures for each model, with the door style and seat width where the sources list them.

What the differences mean: the spread between the lowest and highest lip is about 3 inches, and for a bather who shuffles rather than lifts a foot, that gap decides whether the entry is a small step or a real one. The Monaco and Mobile put the lip lowest, the Transfer32 is close and adds an L-shape opening so a wheelchair user need not step at all, and the Ultra and Elite sit higher on the drawing but can be set lower by the installer. Because the figure on the drawing is the starting point and the installation decides the final height, the model choice and the installer's plan should be made together. The full list is kept in What Is the Step-In Threshold on a Walk-In Tub?.

How In-Home Installation Changes the Threshold

The threshold height is really the height of the tub floor above the finished bathroom floor. The tub sits on adjustable leveling legs, and the spec sheet drawing shows the factory frame height with the legs at their standard setting. Two things move that number: a recessed drain lets the tub sit lower, and a different leg setting raises or lowers the frame. Thresholds can be reduced to about 3 to 3.5 inches by setting the tub lower with the drain below the subfloor, which is the same idea the legacy S-Class used for its 3 inch version, so it is a choice to make before the tub is ordered and before the floor is opened.

• Ella does not send technicians. The tub, the manuals and any warranty parts ship to you, and a local licensed plumber and electrician you hire do the labor in your home.
• Talk with your installer about the target step height before the tub goes in, because a drain below the subfloor has to be planned while the floor is open.
• Cutting the apron or end panel to make a lower set work voids coverage on those altered panels only, not on the rest of the tub.
• After installation, keep an eye on the leveling legs. A leg that loses contact with the floor can warp the frame and throw the door out of alignment.

What the Lifetime Warranty Covers, and What It Does Not

The Lifetime Limited Warranty covers the bathtub shell, frame, door, door seal and finish, along with the supporting equipment: motors, pumps, fixtures, electronic controls, faucet, waste and overflow. Coverage is for parts only. It applies to the first purchaser, is nontransferable and is tied to the original installation address, so it is void if ownership changes or the tub is relocated, and it excludes tubs modified or repaired by anyone other than Ella's Bubbles. Labor, installation, removal and water damage to the home are never covered. The thermostatic control valve is the one exception on the tub itself, with a 1-year limited warranty. After a claim is verified, the part ships to the original customer's address without charge and your local licensed plumber fits it. The door and its seal are covered parts, as Does the Ella Lounger Walk-In Tub Door Leak Over Time? explains for the outward U-door family. Two points matter for a buyer comparing lifetime warranties. First, the warranty is put in force only when the 2-page activation form, signed by both you and your installer, is returned to Ella's Bubbles, so keep that paperwork with your order. Second, showers, shower doors, seats and faucets carry their own separate published terms, summarized in Warranty Terms for Showers, Shower Doors, Seats, Faucets, Alcove Tubs and the Pet Spa, so do not assume an accessory bought alongside the tub shares the tub's lifetime coverage.

The Safety Features Every Model Shares

A low lip is only the first of the moves a walk-in tub removes. A conventional bathtub asks the bather to lift a leg over the rim, lower down to the tub floor and later stand up from that floor on a wet surface. Every Ella walk-in tub replaces those moves with a textured slip-resistant floor, wall and deck grab bars, a molded seat and a door that seals without effort: a chrome stainless steel latch pulls an inward-swing door tight against its seal, and the outward U-shape doors secure with three latches. Oversized easy-turn drain openers with a large 2 inch drain and a safety chain let the tub empty without bending for a small stopper. Seat width is where models differ most once the bather is inside, from the Mobile's 19 to 20 inch seat to the S-Class 21 inch seat, the Royal's 23 inch seat, the widest in the stainless family, and the Front Entry's 25 inch seat on the spec sheet, quoted as 24 inches in its video. The second video is a short owner's account of the low threshold entrance making it easy to get in and out, followed by the light chromatherapy option.

What to Have Ready Before You Ask

1. The model or models you are comparing and the threshold figure from the table above.
2. A tape measurement of your existing tub rim and, if you already own an Ella tub, from the finished floor to the top of the lip.
3. Your installer's view on whether the drain can go below the subfloor.
4. For an owned tub, the serial number from the label behind the magnetic access panel next to the door.

With those in hand, open a ticket at ellasbubbles.com/support or call (800) 480-6850 and the team can confirm the threshold for your model and installation plan.
