Legacy Ella Models: Chi OAC3252, Malibu OA3052, Tramo WT5932 and the Gel Coat Wheelchair-Access Line

Updated September 2026

Legacy Ella models such as the Chi OAC3252, the Malibu OA3052, the Tramo WT5932 wheelchair transfer tub and the gel coat wheelchair-access line are no longer in production, but many are still in daily use, and Ella's Bubbles, founded in 2005, still supports them with lifetime technical support and a Legacy Parts section. Below are the printed facts for each line, the older manuals that apply to 2017 and 2018 outward-swing tubs, and how parts and support work. For a discontinued model the sheet printed for it is the reference, and the team confirms anything that affects your serial number.

Chi OAC3252 (sheets Dated 11/10)

The Chi was an outward-swing acrylic walk-in tub offered in many configurations, each with its own sheet: soaking, hydro, air, dual (air plus hydro), microbubble and heated-seat combinations, with either the Huntington Brass fast-fill faucet (HB models) or a thermostatic faucet set (TCV models). Shared body facts:

  • Actual size 32 by 52 by 42 inches; shipping size 34 by 54 by 50 inches; net 220 pounds; shipping 300 pounds.
  • Water capacity 90 gallons unoccupied, 55 to 75 gallons occupied.
  • 7 inch step-in threshold, which could be lowered to 4 inches with a below-the-floor drain installation.
  • Seat 23 inches wide, 17 inches high and 14 1/4 inches long; three front and one end access panels; extension panel for a 60 inch opening; wall and deck mounted stainless grab bar; LED chromatherapy and aromatherapy on the dual models.
  • Dual model therapy: 16 air jets on a variable-speed 4.5 amp pump with auto purge, and 9 adjustable plus 4 fixed hydro jets on a 5 amp pump with a 650 watt in-line heater and intensity control, run from a digital control. Two 2 inch floor drains with two PVC drain elbows.
  • Electrical: one dedicated 120 volt line with a 20 amp GFCI outlet.
  • Warranty as printed: lifetime limited on the acrylic shell, frame and door; 5 year parts warranty excluding the faucet; the Huntington Brass faucet set carried a 10 year limited warranty under the faucet maker's terms, and the TCV faucet set a 1 year warranty.

Malibu OA3052 (sheet Dated 11/10)

The Malibu was a hydro massage walk-in tub in left-drain (OA3052-L) and right-drain (OA3052-R) versions: actual size 29 1/2 by 52 by 43 inches, shipping size 32 by 54 by 50 inches, net 220 pounds and shipping 350 pounds, 90 gallons unoccupied and 55 to 75 occupied, a 4 inch step-in threshold, a seat 22 1/2 inches wide and 17 inches high, two front and one side access panels and a wall-mounted chrome grab bar. Its hydro system had 9 adjustable and 4 fixed jets on a 7 amp pump with a 650 watt in-line heater, ozone, a push control and an intensity control. The 5-piece brass faucet set included a thermostatic control valve, two diverters and a pull-out hand shower on a 5 foot hose. It had one 2 inch floor drain with a pull-up safety chain, a copper overflow and a cable-operated opener, on a dedicated 120 volt line with a 15 amp GFCI breaker. Printed warranty: lifetime limited on shell, frame and door, 5 years on parts. The team has described the current Capri as the successor to the Malibu's 30 by 52 outward-swing footprint.

Tramo WT5932 Wheelchair Transfer Tub (sheets Dated 04/15)

The Tramo was an earlier wheelchair-transfer tub with an outward-opening waterproof door and a textured ABS acrylic shell, offered as soaking (WT5932S), air massage (WT5932A) and nano massage (WT5932H), each with left or right door and drain. Body facts: 32 by 59 by 33 inches, shipping size 38 1/2 by 64 by 42 1/2 inches, net 196 pounds and shipping 276 pounds on the massage versions (186 and 266 on the soaking version), 50 gallons unoccupied and 30 to 40 occupied, a 17 inch door entry height, a 26 inch bathing area width, an anti-slip floor, one grab bar, a pillow headrest and a front access panel. The air version had 16 air jets on a 0.66 HP heated blower; the nano version had 42 variable massage jets with an in-line heater and chromatherapy. Plumbing used 1/2 inch NPT braided supply hoses and a 2 inch drain, on a dedicated 110 volt circuit with a 15 to 20 amp GFCI. Printed warranty: limited lifetime on the door seal gasket and 3 years on hardware and components. It was replaced by the Transfer family with the L-shape door.

Gel Coat Wheelchair-Access Line, Models 325201 to 325204 (sheets Dated 07/14)

Before the acrylic Transfer family, Ella offered a gel coat fiberglass wheelchair-access tub in four versions: 325201 soaking, 325202 air, 325203 hydro and 325204 dual massage, each left-hand or right-hand and in a white or biscuit shell. Shared facts: 32 by 52 by 41 inches, shipping size 34 1/4 by 54 by 49 inches, 100 gallons unoccupied and 65 to 85 occupied, a 7 inch threshold, a 17 inch seat height and 22 inch seat width, an anti-slip floor, a built-in grab bar, removable access panels and a wall extension kit for a 60 inch opening. Net weight ran from 180 pounds (soaking) to 215 pounds (dual). The dual version had 18 air jets on a three-speed heated pump with auto purge and 6 adjustable hydro jets with an in-line heater. The chrome 5-piece Roman faucet was installed by the customer's contractor in an undrilled deck; plumbing used two 30 inch supply lines with 3/4 inch connections and a 1 1/2 inch quick drain with overflow. Printed warranty: 25 years on the tub body, lifetime on the door seal and air jets, and 5 years on the faucet and pumps.

Legacy Visuals: The S-Class and the Early Outward-Swing Line

This video presents another legacy line, the S-Class 3052 and 3060 low-entry tubs in their 6 inch threshold version: a 21 inch seat, textured floor, grab bars, towel rack, stainless door latch, three-speed air with auto purge, hydro with in-line heater and dial, and an oversized 2 inch drain with a safety chain. The 6 inch threshold, unlike the 3 inch version, leaves room for floor jetting. The S-Class article covers that series in full.

This overview of the outward-swing U-door tubs names the Malibu alongside the Lounger, Front Entry and Mobile, and shows the dual 2 inch drains on most models, the single drain with emergency pull chain on some, the three-latch lock, air with auto purge, hydro with in-line heater, ozone, the 5- or 2-piece faucet, and the options of the period: microbubble, chromatherapy, aromatherapy, heated seat, 4-fold screen, pillows, and push buttons or a digital touchpad.

Which Manual Covers a 2017 or 2018 Outward-Swing Tub?

Two generations of older owner's manuals exist for the outward-swing family. The 08/17 "Ella Outward Swing Door Walk In Baths Owners Manual" covers the Malibu OA3052, Lounger OA2660, Tub4Two O2SA3060, Monaco OA3252 and Transfer OAL3052. The 03/18 manuals are split by therapy system: an air massage edition covering Malibu OA3052A, Lounger OA2660A, Tub4Two O2SA3060A, Monaco OA3252 and OA3252A and Transfer OLA3052A, plus matching hydro, dual, air plus microbubble and hydro plus microbubble editions for the same five models. All are legacy documents; for any current outward-swing tub the 6/15/23 outward-swing-door manual on the product page governs, and where the two differ on a procedure for a current tub, follow the current one. The older manuals and current warranty article explains why the printed warranty terms also differ.

Parts and Support for an Older Tub

Start with the serial label behind the access panel next to the door (see where to find your model and serial numbers) and the model and part code decoder for legacy model numbers such as OA2660 or WT5932. Technical Support keeps legacy items such as the TCV regulator, drain assemblies, door latches and older controllers, or identifies a current equivalent; the parts and support for older tubs article lists what is typically available.

Common Questions

What is a Chi or Malibu tub?
Early acrylic outward-swing walk-in tubs from 2010-era sheets. The Chi is 32 by 52 with a 7 inch threshold and many therapy configurations; the Malibu is 29 1/2 by 52 with a 4 inch threshold and a hydro system.
Is the Malibu still made?
No. The team describes the current Capri as the tub that took over the Malibu's 30 by 52 outward-swing footprint. For parts on an existing Malibu, use your serial number.
What is the Tramo transfer tub?
A 32 by 59 inch wheelchair-transfer tub from 2015 sheets with a 17 inch door entry height, sold in soaking, air and nano massage versions. It is discontinued; the current Transfer family replaces it.
Do these tubs still get parts?
Yes. Ella's Bubbles keeps a Legacy Parts section on ellasbubbles.com and provides lifetime technical support. Open a ticket with your model, serial number and a photo of the part, and the team will identify the replacement or the closest current equivalent.
My legacy tub used a Huntington Brass or TCV faucet. Can it be replaced?
Yes. The TCV regulator is on the Legacy Parts page, and where a faucet maker has closed the team can suggest a compatible Ella faucet or cartridge; see the TCV replacement article for supply-input sizes.

For anything model-specific, including the exact spec sheet for the tub on your order, open a ticket at ellasbubbles.com/support or call (800) 480-6850 and the team will be glad to help.
