American Standard Evolution 60 x 32-Inch Deep Soak Drop-In Bathtub With EverClean Combination Spa System - AMS-2422V418C

Frame to the tub's actual outside footprint, not the nominal size. The Evolution deep soak drop-in measures 62.75 inches long by 34.75 inches wide overall, with a 25.5 inch height, while the nominal bathing dimensions are given as 60 x 32 x 21-1/2 inches (1524 x 813 x 546 mm). The extra length and width is the rim that sits on the deck, so the cutout in the deck goes inside that.

Yes, and it has to be the right one. The Evolution deep soak drop-in requires the Deep Soak Max Drain, which is ordered separately from the tub. The deep soak overflow height is what makes the higher water line possible, so a standard tub waste and overflow will not give you the soaking depth the tub is built for.

Both installs are supported. The Evolution 60 x 32 is a drop-in tub with an undermount option, so you can either set it into a finished deck on its rim or undermount it beneath a stone or solid surface deck. Undermounting hides the rim and puts the deck material right to the bathing well edge, but it takes the deck fabricator's cutout template rather than a simple framed opening.

No mortar bed needed. The Evolution deep soak drop-in has a pre-leveled tub bottom, so it sits flat on the framed platform without a poured base. That is a real time saver on a remodel where you are working over an existing subfloor.

The Evolution combination spa tub uses American Standard's EverClean system, which addresses the circulating plumbing behind the jets. In a combination unit you have both water jets and air channels, and those lines hold residue after a drain, so a built-in treatment of the system is the difference between a whirlpool you can live with long term and one that needs constant flushing.

The Evolution combination spa system tub is classified as a residential product in the Evolution family. For hospitality or multi-family specs, check the project's requirements against a commercially classified tub rather than assuming this one carries the same approval.

White only. The tub ships as model 2422V418C.020, and the .020 suffix is American Standard's white. If you are matching other fixtures in the room, that is the single finish to plan around.

It has dual molded-in armrests formed into the acrylic shell, not add-on pieces. Worth knowing when you compare interior room against a plain-wall soaker of the same 60 x 32 footprint, since the armrests take up some of the well width.
