The best 72-inch drop-in soaking tub depends on your available width, preferred drain layout, and whether you want a simple bath or added features. The Kohler Underscore is best for buyers who want a 72-by-42-inch tub with drop-in or undermount installation. ANZZI and Swiss Madison offer 72-inch soaking options, while the WOODBRIDGE model is a feature-rich alternative—but it is freestanding, not drop-in.
| Product | Best For | Key Detail |
|---|---|---|
| Kohler Underscore | Wide deck or undermount layouts | 72 x 42 inches; two installation styles |
| ANZZI Illyrian | Simple, non-jetted soaking | Marine-grade acrylic with fiberglass reinforcement |
| Swiss Madison Voltaire | Flexible drain placement | Reversible drain |
| Swiss Madison SM-DB567 | Drop-in design with reversible drain | Fiberglass-reinforced acrylic |
| WOODBRIDGE Double Slipper | Soaking with jets and heat | Freestanding rather than drop-in |
Kohler Underscore 72-Inch Drop-In Bath
The Kohler Underscore measures 72 inches long by 42 inches wide and 23 inches high. Its listed installation options are drop-in and undermount, giving buyers flexibility when planning the surrounding deck or bathroom finish. The clean, simple design is intended to coordinate with a range of products and styles.
Best for: Buyers with room for a wider tub who want the choice between drop-in and undermount installation. It is selected for its stated dimensions and installation flexibility.
Consider: The 42-inch width may require more floor and deck space than a 36-inch-wide option. Confirm the bathroom opening and framing dimensions before choosing it.
ANZZI Illyrian 72-Inch Soaking Tub
The ANZZI Illyrian is a 36-by-72-inch rectangular, non-jetted soaking bathtub. Its product details describe marine-grade acrylic reinforced with fiberglass, a glossy ultra-white finish, and a design intended for everyday use. The listed features also emphasize straightforward cleaning and maintenance.
Best for: Buyers who want a 72-inch soaker without jets or electrical wiring. It stands out for its non-jetted design and described acrylic construction.
Consider: The supplied product details do not state the tub’s height, bathing capacity, or drain location. Check those specifications and verify the installation requirements before purchase.
Swiss Madison Voltaire Reversible-Drain Tub
This Voltaire is a 72-by-36-inch drop-in soaking tub with a reversible drain, according to the product name and listed features. The description says it has no tile flange and uses fiberglass-reinforced acrylic. Reversibility can help accommodate different drain layouts, but the specific rough-in arrangement should be confirmed for the model.
Best for: Buyers seeking a 72-inch drop-in model with more drain-placement flexibility. It is selected for its stated dimensions, drop-in format, and reversible drain.
Consider: The product information does not provide a height or bathing capacity. Verify these details, along with the drain setup, before finalizing a bathroom plan.
Swiss Madison SM-DB567 Voltaire Drop-In Bath
The SM-DB567 Voltaire is listed as a 72-by-36-inch drop-in bath. Its features include a reversible drain and fiberglass-reinforced acrylic. The supplied description also notes the absence of a tile flange, a detail that can affect how the tub is integrated with a surrounding deck or finished wall.
Best for: Buyers comparing 72-by-36-inch drop-in tubs who need a reversible drain layout. It shares the Voltaire’s core listed features and may suit projects where drain orientation is still being planned.
Consider: The product details do not specify height, capacity, or whether other components are included. Confirm the exact model’s installation documentation and included parts.
WOODBRIDGE Double Slipper Whirlpool And Air Tub
This 72-by-35⅜-inch WOODBRIDGE tub combines whirlpool and air-bubble jets, with 16 jets, an adjustable air blower, and an inline heater controlled through an LED panel. Listed specifications include a 65-gallon effective capacity and a water depth of 14½ inches to the overflow. The product is described as freestanding, so it is not a direct match for a standard drop-in installation.
Best for: Buyers prioritizing massage jets and heated soaking who are open to a freestanding tub. It is included as a feature-rich alternative in the same general length range.
Consider: Avoid this option if a drop-in tub is required. Its electrical features and freestanding format call for planning beyond a basic drop-in installation.
Buying Guide: How To Choose A 72-Inch Drop-In Soaking Tub
Which tub width fits the bathroom?
Length alone does not determine fit. The listed choices include 36-inch-wide models and a 42-inch-wide Kohler option. Measure the intended opening, deck, access route, and surrounding clearances. Also check height and rough-in details, which are not supplied for every model here.
Do you want a basic soaker or powered features?
A non-jetted tub, such as the ANZZI, avoids the electrical features associated with a powered model. The WOODBRIDGE adds whirlpool and air jets plus an inline heater, but it is freestanding. Match the product type to the planned installation rather than choosing by length alone.
How important is drain placement?
A reversible drain may offer more flexibility when a bathroom’s plumbing layout is being planned. The Swiss Madison Voltaire listings identify a reversible drain. Confirm the manufacturer’s installation instructions and the drain position for the exact model before plumbing work begins.
What should you verify before ordering?
- Confirm the full dimensions, including height and width, against the bathroom plan.
- Check whether the tub is drop-in, undermount, or freestanding.
- Verify drain location, overflow details, and required plumbing clearances.
- Review installation instructions and determine what components are included.
- For powered tubs, plan for the electrical requirements specified by the manufacturer.
