Anzzi Coupe Series Walk-In Tubs: Soaking vs. Air vs. Whirlpool Compared
Anzzi's Coupe Series walk-in tubs are some of our most popular — and most confusing — products. Every model shares the same core safety design (low entry threshold, built-in grab bar, ADA-compliant seating), but the lineup splits across four independent choices at once: tub size, drain side, therapy type, and color. That means two tubs with nearly identical names can be $1,000+ apart in price and completely different in what they actually do. Here's how to tell them apart.
The Four Things That Actually Differ
- Size — six footprints in the Coupe line, from a compact 27 in. x 39 in. up to a spacious 30 in. x 60 in. Your existing tub alcove usually determines this for you.
- Drain side — Left or Right. This refers to which side the door and drain sit on, and it needs to match your bathroom's plumbing rough-in and door swing clearance.
- Therapy type — Soaking, Air, Whirlpool, or Whirlpool + Air. This is the biggest price and feature difference, and the one buyers get wrong most often.
- Color — White or Biscuit.
Soaking vs. Air vs. Whirlpool vs. Whirlpool + Air
This is the choice that actually changes what the tub does. Here's exactly what each one includes:
| Type | What It Does | Jets | Extras | Electrical Needed | Typical Price |
|---|---|---|---|---|---|
| Soaking | A deep, non-jetted soak — no massage function | None | None | No | $3,324–$3,900 |
| Air | Full-body aero-therapy — a gentler, bubbling massage from wall-mounted air jets | 26 air jets | Aromatherapy, Chromatherapy | Yes (110V, ~1,650W) | $4,392–$4,800 |
| Whirlpool | Targeted water-jet massage aimed at the back and legs, plus a fast powered drain | 13 hydro jets (9 directional + 4 V-shaped back jets) | Chromatherapy, Maintenance Heater, HD Powered Fast Drain | Yes (110V, ~1,650W) | $3,995–$4,500 |
| Whirlpool + Air | Both therapies combined — full-body air massage plus targeted water jets | 39 total jets (13 hydro + 26 air) | Aromatherapy, Chromatherapy, Maintenance Heater, HD Powered Fast Drain | Yes (110V, ~2,200W) | $4,449–$5,600 |
How to Choose a Therapy Type
- Just need safe, easy bathing? Soaking is the simplest and least expensive option — no electrical work required, since there's nothing to wire in.
- Want a gentler, full-body massage without direct water pressure? Air jets bathe the entire body in bubbles rather than targeting specific spots — popular with users who find whirlpool jets too intense.
- Dealing with specific back or leg pain? Whirlpool's directional hydro jets target those areas directly, and it includes the HD Powered Fast Drain other types don't (except Whirlpool + Air).
- Want it all? Whirlpool + Air is the only option with every therapy, extra, and the fastest drain — it's also the most expensive tier and pulls the most power (2,200W vs. 1,650W for the single-therapy options), so confirm your bathroom's circuit can support it before you buy.
Size Guide
The Coupe Series is available in six footprints: 27 in. x 39 in., 26 in. x 53 in., 29 in. x 52 in., 30 in. x 53 in., 30 in. x 60 in., and 32 in. x 38 in. Not every size is available in every therapy type — measure your existing tub alcove first, then check the specific size against our full Anzzi collection to see which therapy options exist at that footprint. All Coupe tubs include a matching extension kit for retrofitting into a standard 60 in. alcove opening.
Left vs. Right Drain
The drain side refers to which side the door and drain sit on when facing the tub. This should match your existing plumbing rough-in — if you're replacing an existing tub, the current drain location is almost always the easiest and least expensive option, since it avoids relocating supply and drain lines.
What's the Same Across Every Coupe Tub
Regardless of size, drain side, therapy type, or color, every Coupe Series tub includes the same core safety package: a low entry threshold, built-in Safe Reach grab bar, slip-resistant textured flooring, ADA-compliant contoured seating, a wide-opening door with a lifetime-warranty watertight seal, and a Quick Fill faucet with a 60 in. handheld shower head. The therapy type changes what happens once you're in the tub — the safety features don't change at all.

Soaking Tub, the 29 in. x 52 in. Air Tub, the 29 in. x 52 in. Whirlpool Tub, and the 29 in. x 52 in. Whirlpool + Air Tub — all the same footprint, so you can see exactly how the therapy tiers compare in price.
