Ella Flow 28x48: The Tub That Fits a 28 Inch Doorway

Updated September 2026

The Ella Flow walk-in tub is the compact hydro tub built to pass a 28 inch doorway: actual size 28 inches wide by 48 inches long by 36.5 inches high, a 20 by 13 inch seat, 65 gallons unoccupied (30 to 50 occupied), and 16 hydro jets with an in-line heater. It is the only Ella tub whose spec sheet calls for a 15 amp GFCI outlet, and it ships with an extension panel so it can still fill a standard 60 inch alcove.

Dimensions

  • Actual 28 x 48 x 36.5 in. The drawing shows 47 3/4 in overall length, 27 3/4 in shell width, 39 3/8 in inner length, a 16 1/2 x 22 1/2 in foot well, and a 96 degree backrest.
  • Seat 20 in wide, 13 in long; crate 32 x 54 x 49 in; net 210 lb, shipping 310 lb.
  • Inward-swing acrylic S-shape door with the handle inside, held shut by water pressure; see how to open and close the inward acrylic door.

Narrow Doorways and Small Rooms

The video presents the Flow as fitting through a 28 inch doorway; the 27 3/4 inch shell is what passes, and the 32 inch crate can be opened outside. The team suggests compact models like the Flow for mobile homes and trailers, and the mobile homes and condos guide covers subfloor and drain planning. For RVs, the team has no direct installation experience, so the RV's floor structure and plumbing capacity must be confirmed by the owner before ordering. Availability of the Flow has varied, so check with your Ella dealer or the team when you plan.

What Is Included

  • Hydro: 16 jets, 8.1A 900W pump, intensity dial, 6A 650W in-line heater, push control, with foot and calf jets.
  • 2-piece fast-fill faucet (up to 16 GPM) with two 3/4 in by 5 ft supply lines and a 5-setting hand shower, in chrome or brushed nickel.
  • One 2 in gravity drain on a T-type dual-port body with overflow and emergency pull chain. The Standard, Zen and Flow installation tips explain the single-drain platform.
  • Removable front apron, removable end panel covering the faucet, and an extension panel for 60 in alcoves.
  • Optional heated seat and backrest (4A) and a removable head and neck support.

Electrical

The pump and heater plug into one dedicated 110/120V line with a 15A GFCI outlet, where other Ella tubs specify 20A. Your electrician should still test the GFCI and confirm local code; the electrical common questions article covers 15 versus 20 amp circuits in more detail.

Extension and Side Panel

  1. The Economy extension kit holds 2 L-shaped stainless brackets, 1 L-shaped plastic bracket, 2 pressure metal clips, and four 1/2 inch nuts. Mount the three brackets, clamp the panel flush with the top and front, pre-drill 3/8 in oversize, fasten with seven screws, and silicone the seams.
  2. Cut the side panel 3/8 in for a flush wall fit: tape it, mark a line top to bottom, clamp a straight edge, cut with a saw blade, then attach it with the magnets on the frame.

Watch the Flow

The video shows the Flow passing a 28 inch doorway, its 38 inch interior, 20 inch seat and 13 inch seat length, the extension panel for 60 inch alcoves and the end panel on the faucet side, hydro with heater and foot and calf jets, the 2-piece faucet, the dual-port drain with pull chain, the single GFCI connection, and the optional head and neck support.

Flow Versus the Other Compact Tubs

The Mobile is smaller still at 26 by 45 inches with an outward door, the Front Entry puts the door on the end for 40 inch spaces, and the Petite is the narrowest stainless-door tub at 27.5 inches actual. The Flow is the one that combines an inward door, a 15 amp circuit and a 28 inch doorway, with the Standard and Zen as its longer hydro-only siblings.

Common Questions

Is there a soaker or air version of the Flow?
No, the Flow is hydro-only.
Does it come with a grab bar?
The Flow spec sheet does not list a grab bar or towel bar; ask the team about add-on options before ordering, and see grab bars included and add-on.
Why does the Flow need only 15 amps?
Its single hydro pump and heater draw less than the multi-system packages on larger tubs, so the spec sheet calls for one 15 amp dedicated GFCI line. A 20 amp dedicated circuit is also acceptable; your electrician decides against local code.
Will it really pass a 28 inch doorway?
The shell is 27 3/4 inches wide, so it passes a 28 inch opening with the side panels removed and the crate opened outside. Measure every hallway and turn between the entrance and the bathroom.
Does it fit a 60 inch alcove?
Yes. The extension panel is included and the side panel is cut 3/8 inch for a flush wall fit, as shown above.
Can I put the Flow in a mobile home or RV?
Mobile homes, yes; the team suggests the Flow and other compact models for them. For an RV the team has no installation experience, so the floor structure and plumbing must be confirmed by the owner first.
Is brushed nickel available?
Yes. The 2-piece fast-fill faucet on the Flow comes in chrome or brushed nickel; the rest of the trim stays chrome.
How does the single drain connect to 1.5 inch house plumbing?
With a standard 2 inch to 1.5 inch reducing fitting ahead of the P-trap; the unused port on the T-type body is capped. See connecting the 2 inch drain to 1.5 inch plumbing.
