This page explains the labeled component diagram printed in the Ella's Bubbles Two Seats Acrylic Walk-In Tubs brochure. The diagram shows a Big4Two 36 with the Air plus Hydro therapy option, and every callout on it is covered here. We also compare the brochure's sizes with the jet counts on the Big4Two and Escape spec sheets.
What the Brochure Diagram Shows
The brochure covers four models: Big4Two, Escape, Tub4Two and Companion. It uses one illustration of the Big4Two 36 with the Air plus Hydro option and labels each visible part. Most of what is on the diagram also appears on the other two-seat tubs, though jet counts and door swing vary by model and therapy option. The two-seat comparison guide lays the four side by side, and the Big4Two profile looks at the pictured model in depth.
Here is the full callout list as printed on the diagram:
| Callout on the diagram | What it is |
|---|---|
| Back hydro massage jets | Water jets in the backrest of each seat |
| Upper air massage jets | Air jets in the upper seat and back area |
| Hip & thigh hydro massage jets | Water jets aimed at the hips and thighs |
| 4 foot hydro jets (each seat) | Water jets at the footwell, four for each seat |
| Lower air massage jets | Air jets low in the seat area |
| 2" dual drain plugs | The two 2" floor drains |
| Hydro inlet | The intake that feeds water to the hydro pump |
| Door handle | The handle on the door |
| Bidet air massage jets | Air jets positioned in the seat |
| Pull-out adjustable hand mixer | The pull-out hand shower with adjustable spray |
| 2 drain openers | The two cable-operated drain controls on the deck |
| Dual spout | The fill spout of the fast-fill faucet |
| LED chromatherapy light | The multicolor LED light |
| Digital Push Control | The pad that runs hydro, 3-speed air, the LED light and the foot jets |
| Hydro intensity dial control | The dial that adjusts hydro jet strength |
Two Seats, Two Sets of Foot Jets, One Dual Spout
Two molded seats face each other, and the callout "4 foot hydro jets (each seat)" makes the point that every bather gets their own footwell massage. Likewise there are two drain plugs and two drain openers, one for each drain. Ella calls this Dual Drain Technology: gravity-driven, oversized 2" drains with independent stainless steel cable controls.
The dual spout is the fill spout of the fast-fill faucet, and it is paired with the pull-out adjustable hand mixer. The brochure lists the faucet as the Ella 5-piece or 2-piece fast-fill faucet in chrome, with two 5' supply lines included and a hand shower with 5 water pressure modes.
The Digital Push Control
Where most of Ella's single-seat tubs use separate push buttons for each therapy, the two-seat family uses a single Digital Push Control pad. The callout spells out what it runs: hydro massage, 3 air speed massage, LED light control, and hydro foot jets on and off. The hydro intensity dial control sits alongside it and adjusts how hard the water jets push. For how the pad differs from button controls, see push button controls versus the digital touchpad.
Jets by Location
The diagram divides the jets by where they touch your body. Water jets (hydro) cover the back, the hips and thighs, and the feet. Air jets cover the upper seat area, the lower seat area, and the bidet position in the seat.
The diagram labels jet positions but does not print totals; the spec sheets do (see the last section). The brochure lists the family's jetting options as Soaking, Air, Hydro, Air plus Hydro, Microbubble combinations, and independent foot and calf massage. Infusion Microbubble Therapy is an available upgrade, as is a Heated Seat and Back with radiant surface heaters.
Included Features and the Dual Drain
Beyond the callouts, the brochure lists what comes with every two-seat tub: 2 molded seats, inward or outward swing doors depending on the model, a pull-out hand shower with 5 water pressure modes, the Ella fast-fill faucet with two 5' supply lines, an LED chromatherapy light, deck and wall grab bars, a textured floor, and a reversible end panel. Dual Drain Technology is described as dual 4-port or 2-port 2" oversized drains with independent stainless steel cable controls.
The Big4Two and Escape spec sheets are more precise: two 2" 4-port PVC drains with 2 end caps included, 2 overflows, and 2 stainless steel operated openers with extended handles in chrome finish. The house drain can connect to either or both ports, and the included caps close the unused ports.
Optional accessories in the brochure: Heated Seat and Back, Ella 4-Fold Shower Screen, 10" Rain Shower Column Kit, and Headrest Neck Support.
Sizes on the Brochure Versus the Spec Sheet
Sizes as printed in the brochure:
| Model | Size as printed in the brochure |
|---|---|
| Big4Two | 36"W x 80"L |
| Escape | 36"W x 72"L |
| Tub4Two | 32"W x 60"L |
| Companion | 32"W x 60"L |
One thing to watch: the cover panel lists "ELLA BIG4TWO" twice, at 36x80 and at 32x60. The second entry is a labeling slip; the Models and Sizes list inside clarifies that the 32x60 two-seaters are the Tub4Two and the Companion. Other known brochure misprints are collected in brochures and catalogs by tub family.
The spec sheets add the jet counts the diagram leaves out, and the two largest models differ a little:
| Spec sheet value | Big4Two (36x80) | Escape (36x72) |
|---|---|---|
| Hydro upper seat jets | 16 (8 on each seat) | 18 (9 on each seat) |
| Hydro foot and calf jets | 4 foot and 4 calf | 4 foot and 4 calf |
| Air seat jets | 18 (9 on each seat) | 16 (8 on each seat) |
| Air foot jets | 4 | 3 |
| Air pump | 3 speed, auto-purge | 3 speed, auto-purge |
| Door | Outward swing | Inward swing |
The Digital Controller named on the spec sheets corresponds to the Digital Push Control labeled on the diagram. When a jet count does not match the diagram, confirm which model and therapy option was ordered, then check that model's spec sheet.
