The Ella Standard 30x52 and the Ella Zen 30x52 are built on the same hydro-only acrylic platform: the same inward-swing S-shape door, the same 8.1A 900W hydro pump with a 6A 650W in-line heater, and the same single 2 inch gravity drain. The Zen is the budget version, so it carries a 20 by 15 inch seat instead of the Standard's 22 by 18 inch seat, 17 hydro jets instead of 18, and a 2-piece single-lever faucet in place of the 5-piece fast-fill set. The Zen side of the story is told in Ella Zen 30x52 and Zen60 30x60: Budget Hydro Tubs With a Single-Lever Faucet, and this page lines the two tubs up figure by figure, together with their 60 inch versions.
Standard and Zen Side by Side
Every figure below comes from the current spec sheets and the model profiles. The Standard60 and Zen60 are included because most people comparing the 52 inch pair end up asking about the longer tubs as well.
| Model | Actual size (W x L x H) | Seat (W x L) | Water, unoccupied / occupied | Hydro jets | Faucet | Best for |
|---|---|---|---|---|---|---|
| Standard 30x52 | 29 5/8 x 52 3/4 x 37.5 in | 22 x 18 in | 65 gal / 30 to 50 gal | 18 | 5-piece fast-fill, up to 18 GPM | The fullest seat and faucet set in a 52 inch hydro tub |
| Zen 30x52 | 29 1/2 x 52 x 37.5 in | 20 x 15 in | 65 gal / 30 to 50 gal | 17 | 2-piece single-lever, up to 16 GPM | Budget buyers who want the same pump, heater and door |
| Standard60 30x60 | 29.53 x 59.84 x 38 in | 21 x 20.1 in | 106 gal / 70 to 90 gal | 18 | 5-piece fast-fill | A 60 inch alcove with no extension panel, and the only Ella tub with the H2 hydrogen option |
| Zen60 30x60 | 29 1/2 x 59 1/2 x 37.5 in | 21 x 17 in | 95 gal / 55 to 85 gal | 17 | 2-piece single-lever | A longer budget soak that fills a 60 inch alcove on its own |
What the table shows is that the two 52 inch tubs are twins in every measurement that touches your bathroom. They are within a fraction of an inch of each other in width and length, stand the same 37.5 inches tall, hold the same 65 gallons unoccupied and 30 to 50 gallons occupied, ship in the same 32 by 54 by 49 inch crate, and weigh the same 210 pounds net and 310 pounds crated. The differences live inside the tub, in the seat, the jet count and the faucet. Move up to the 60 inch versions and the two lines separate a little more: the Standard60 holds 106 gallons and has a 20.1 inch long seat, while the Zen60 holds 95 gallons on a 17 inch seat and weighs less at 190 pounds net.
What Is Identical on Both Tubs
The Zen was designed as a lower cost way onto the Standard platform, so the parts that matter most for installation and daily use are shared. Both models come with:
- A gloss white acrylic shell reinforced with fiberglass gelcoat, on a stainless steel frame with adjustable leveling legs.
- The inward-swing acrylic S-shape door with the handle inside the tub.
- An 8.1A 900W hydro massage pump, a 6A 650W in-line heater that holds the water temperature, an intensity dial and a push control.
- One 2 inch gravity drain with an overflow and an emergency pull chain, on a T-type body with four ports so the installer can run the drain line in either direction. Unused ports arrive capped.
- Two front access panels and one reversible end panel, a chrome U-shape deck and wall grab bar, and a brushed stainless towel bar.
- An extension panel so either 52 inch tub finishes inside a 60 inch alcove. The Standard's panel is 7 inches.
- One dedicated 20A 120V GFCI outlet, with the 4A heated seat and backrest as the only optional add-on.
- The same owner's manual, and the same limits: hydro-only, no air massage, no soaker version, and no ozone generator listed on either spec sheet.
Because neither tub has an air system, there is no Auto Purge cycle after a bath on either one. The monthly vinegar flush is what keeps the hydro lines fresh, and it applies equally to the Standard and the Zen.
Seat and Jets: Where the Zen Saves
The Standard's seat measures 22 inches wide by 18 inches long. The Zen's measures 20 inches wide by 15 inches long, so it is both narrower and shorter. For a smaller bather that is not a drawback, and a shorter seat leaves a little more room in the same footwell. For a broad or tall bather, the Standard's seat is the reason to choose the Standard.
The Standard has 18 hydro jets and the Zen has 17, and on both tubs the lower jets massage the feet and calves. Those lower jets run on the same single pump as the back jets, so the tub must be filled above them before the pump is switched on, and neither tub offers an independent foot massage. The Standard's video tour gives its interior length as 43 inches and its soaking depth as 15 inches. The Zen profile does not publish those two figures, so if soaking depth is the deciding factor, ask your Ella dealer or the team at (800) 480-6850 to read them from the drawing.
The Faucet: Five Pieces or One Lever
This is the most visible difference on the deck. The Standard ships with the 5-piece Ella fast-fill set: a solid brass chrome spout, separate hot and cold levers with a diverter, and a pull-out hand shower with five spray settings on a 5 foot braided hose. It is designed for up to 18 GPM at 60 PSI under ideal in-home plumbing conditions and includes two 3/4 inch by 5 foot braided supply lines that connect to your shut-off valves.
The Zen ships with the 2-piece single-lever fast-fill faucet, offered in chrome or brushed nickel. Lift the lever for on, push it left for hot and right for cold, and press the diverter button under the spout to send water to the hand shower. The faucet fill rate is listed at up to 16 GPM, and its deck cut-outs are a 2-1/2 inch hole for the faucet body, a 1/3 inch hole for the mounting rods and a 7/8 inch diagonal hole for the hand shower. On both tubs the hand shower itself is limited to 1.9 GPM, so the faucet choice changes fill speed and the look of the deck, not the hand shower.
The Door, the Room and the Alternative at 30x52
Both tubs use the inward-swing acrylic S-shape door described in What Is an S-Shape Inward-Swing Door on a Walk-In Tub?. The Zen's spec sheet prints "U-shape" for its door, and that is a known misprint: U-shape names Ella's outward-swing composite door family, and the Zen uses exactly the same S-shape door as the Standard. The routine is the same on both: open the door into the tub, step in, close and latch it while standing, then sit and fill. Water pressure holds the door shut, and it will not open until the tub has fully drained. Because the door swings into the tub, neither model needs clear floor space in front of it, which is why this platform suits smaller bathrooms. The door video on this page shows Ella's five door styles side by side, including the S-shape inward swing door, and points out that it is the outward-swing doors that need a 20 inch swing clearance.
If you like the 30x52 footprint but want air massage, a soaker with no jets, or dual drains, the tub to look at is the Ella Elite 30x52, which uses the inward-swing brushed stainless steel door, a 22 inch seat, 75 gallons unoccupied and five therapy configurations. It is the stainless-door counterpart to the acrylic pair, and the profile in Ella Standard 30x52 and Standard60 30x60: Hydro-Only Value Tubs spells out the hydro-only limits that the Standard and Zen share.
Choosing Between the 60 Inch Versions
The Standard60 measures 29.53 by 59.84 by 38 inches, holds 106 gallons unoccupied and 70 to 90 gallons occupied, ships in a 32.68 by 61.81 by 47.64 inch crate at 238 pounds net and 359 pounds crated, and can be ordered with the drain on the left or the right. Its diverter switches run the foot and leg jets only, the back jets only, or both, and it is the only Ella tub offered with the H2 hydrogen and microbubble system. The Zen60 measures 29 1/2 by 59 1/2 by 37.5 inches with a 21 by 17 inch seat, holds 95 gallons unoccupied and 55 to 85 gallons occupied, and ships in a 32 by 62 by 49 inch crate at 190 pounds net and 345 pounds crated. Neither 60 inch tub includes an extension panel, because neither needs one in a 60 inch alcove, and both keep the same pump, heater and single 2 inch drain as their 52 inch siblings.
