Which one should you choose?
Choose WOODBRIDGE 59" Matte Black Freestanding Tub if
- You need a freestanding tub that fits into open bathroom spaces.
- You prefer a lighter unit that is easier to handle during installation.
- You want a modern aesthetic with a matte black finish option.
Choose Kohler Villager 60 in Alcove Tub if
- You are installing a tub into a standard three-wall alcove.
- You require a slip-resistant surface for safer entry and exit.
- You need a heavy, rigid tub that stays firmly in place.

Your choice depends on whether you prioritize design flexibility or traditional alcove fitment.
Acrylic vs Cast Iron Tub Specs
Material and Build
The WOODBRIDGE tub uses 100% high-gloss Lucite acrylic reinforced with resin and fiberglass. This double-walled design provides insulation to keep water warm longer. The Kohler Villager relies on durable cast iron construction. This material is known for its strength and long-lasting quality. While the acrylic model offers thermal benefits through its layered build, the cast iron option prioritizes structural rigidity. Both surfaces are designed to maintain their finish over time, with the acrylic featuring stain-resistant properties and the cast iron offering a glossy, easy-to-clean surface.
Mounting Type
Installation style is a major differentiator between these two tubs. The WOODBRIDGE model is a freestanding bathtub, meaning it stands independently and does not require surrounding walls for support. This allows for flexible placement in various bathroom layouts. In contrast, the Kohler Villager is an alcove tub designed for three-wall installation. It features an integral apron that hides the plumbing and provides a finished look against the wall. If you need a standalone centerpiece, the acrylic option is the clear choice. For standard alcove spaces, the cast iron tub fits the requirement.
Dimensions and Size
Size specifications vary significantly between these two models. The WOODBRIDGE acrylic tub measures 59 inches long, 31.5 inches wide, and 22.9 inches deep. The Kohler cast iron tub is slightly longer at 60 inches but narrower at 30.3 inches wide and much shallower at 14 inches high. The acrylic tub offers a deeper soaking experience with its 22.9-inch depth, while the cast iron tub provides a standard bathing height. Your choice depends on whether you prefer a deep soaking vessel or a standard alcove footprint.
Weight and Capacity
The weight difference is substantial and impacts floor support requirements. The WOODBRIDGE acrylic tub weighs 88 pounds, making it significantly lighter and easier to handle during installation. The Kohler cast iron tub weighs 316 pounds, reflecting the density of its material. Despite the weight difference, both tubs are built to hold substantial water. The acrylic model supports up to 1000 lbs of bearing capacity, while the cast iron tub holds between 30 to 40 gallons of water. You must ensure your floor can support the heavier cast iron option.
Drain Location
Drain placement affects plumbing configuration and installation complexity. The WOODBRIDGE tub features a matte black drain and overflow, with the specific location not explicitly defined in the provided specifications beyond the finish. The Kohler Villager specifies a left-hand drain. This precise specification is crucial for aligning with existing plumbing lines in an alcove setup. If your bathroom plumbing is fixed on the left side, the Kohler tub may require less modification. The WOODBRIDGE tub’s drain finish offers aesthetic flexibility, but the exact position requires verification from the full manual.

The integral apron creates a clean look against the walls. This model is ideal if you want a traditional tub that fits into a built-in space.
Someone prioritizing easy maintenance

Frequently asked questions
Are acrylic tubs heavier than cast iron ones?
No, acrylic tubs are significantly lighter. The WOODBRIDGE acrylic model weighs 88 pounds. In contrast, the Kohler cast iron tub weighs 316 pounds. This weight difference affects floor support needs. You must ensure your floor can handle the heavier cast iron option. Lighter acrylic tubs are easier to move and install.
Do acrylic bathtubs come in freestanding styles?
Yes, acrylic is ideal for freestanding designs. The WOODBRIDGE tub is a freestanding unit made of matte black acrylic. It does not require wall mounting. This allows you to place it in the center of a room. Cast iron tubs like the Kohler Villager are typically alcove models. They are designed to fit against three walls.
Which material holds heat better, acrylic or cast iron?
Acrylic often retains heat effectively due to its structure. The WOODBRIDGE tub uses a double-walled design with resin and fiberglass reinforcement. This construction insulates the water, keeping it warmer longer. Cast iron also holds heat well due to its density. However, the specific acrylic insulation provides a notable advantage for maintaining temperature during your soak.
What are the standard sizes for these tubs?
Standard sizes vary by material and style. The WOODBRIDGE acrylic tub measures 59 inches in length and 31.5 inches in width. The Kohler cast iron tub is 60 inches long and 30.3 inches wide. Both fit standard bathroom footprints. The acrylic option offers a slightly wider basin. The cast iron option provides a classic elongated shape.
Can I install a cast iron tub myself?
Installing a cast iron tub is difficult due to its weight. The Kohler Villager weighs 316 pounds. You will likely need professional help to move and secure it safely. Acrylic tubs like the WOODBRIDGE model weigh only 88 pounds. You can handle the acrylic tub more easily. This makes DIY installation more feasible for lighter materials.
Is matte black acrylic durable for daily use?

This construction resists chipping and cracking under normal use. The matte black finish provides a modern look that maintains its appearance over time with proper care.
