Stone Resin vs Cast Iron Specs
Material composition
The ANZZI Bailey tub uses an acrylic and solid surface build, which the manufacturer lists as stone resin in its attributes. This composite creates a lightweight yet durable structure with a smooth, glossy finish. In contrast, the Kohler Villager tub is constructed from cast iron. This heavy metal material is known for its substantial weight and rigid strength. The cast iron construction ensures long-lasting quality and provides a classic, solid feel. While the ANZZI offers a modern composite feel, the Kohler relies on traditional metal durability for its structure.
Installation type
The ANZZI Bailey is a freestanding soaking tub with a flatbottom design. It stands independently on the bathroom floor, offering a space-conscious design that brings comfort to smaller bathrooms. The Kohler Villager is a three-wall alcove tub with an integral apron. It is designed to fit comfortably into standard alcove spaces, requiring walls on three sides for support. This alcove style provides a clean look and easy installation against existing walls. If you need a standalone piece, the ANZZI is the clear choice. If you have an alcove, the Kohler fits that specific layout.
Soaking capacity
Water capacity varies significantly between these two models. The ANZZI Bailey holds 67.4 gallons of water, supporting a 14.8-inch soaking depth. This deep capacity allows for full body immersion and a relaxing bathing experience. The Kohler Villager holds between 30 and 40 gallons of water. Its height is only 14 inches, which limits the depth of the water. The ANZZI offers more than double the water volume of the Kohler. If you prefer deep soaks, the ANZZI provides a more immersive experience due to its higher capacity.
Physical weight
The weight difference is substantial and impacts handling and floor support. The ANZZI Bailey weighs 77.2 pounds. This lighter weight makes it easier to move and install as a freestanding unit. The Kohler Villager weighs 316 pounds. This heavy cast iron construction ensures stability but requires a strong floor to support the load. The Kohler is nearly four times heavier than the ANZZI. You must consider your bathroom floor's load-bearing capacity if you choose the cast iron option. The lighter resin tub is easier to manage during installation.
Drain location
Drain placement affects plumbing compatibility and layout flexibility. The Kohler Villager features a left-hand drain. This specific placement is fixed and must align with your existing plumbing or new pipe installation. The ANZZI Bailey does not specify a left or right drain in its provided data. It is described as having an overflow drain, but the exact lateral position is not listed. If your plumbing is set for a left-hand drain, the Kohler is ready to connect. For the ANZZI, you would need to verify the drain side before purchasing to ensure it matches your bathroom layout.
Surface safety
Safety features differ between the two designs. The Kohler Villager includes a Safeguard slip-resistant surface. This feature is specifically designed to reduce the risk of slipping when the tub is wet. The ANZZI Bailey features a glossy white finish. While this finish is easy to clean and maintain, the data does not mention a specific slip-resistant coating. The glossy surface may be smoother underfoot compared to the textured Safeguard surface. If slip resistance is a priority for your household, the Kohler offers a dedicated safety feature that the ANZZI data does not confirm.
Choose the right tub for your space
Small bathroom owners needing freestanding style
The ANZZI tub fits tighter spaces with a 58.9-inch length and 29.1-inch width. Its freestanding design does not require three walls for support. You get a modern look without sacrificing floor space. The 67.4-gallon capacity allows for deep soaking. This model weighs only 77.2 pounds, making placement easier in smaller rooms.
Users wanting durable cast iron construction
The Kohler Villager features solid cast iron material for lasting strength. This heavy-duty build ensures the tub remains stable over time. The integral apron provides a clean, finished look for alcove installations. You benefit from a slip-resistant surface for added safety. The left-hand drain fits specific plumbing layouts in standard bathrooms.
Shoppers prioritizing deep soaking capacity
The ANZZI model offers a 67.4-gallon water capacity and a 14.8-inch soaking depth. This allows for full body immersion during your bath. The flat bottom interior provides stable seating for long soaks. You enjoy a glossy finish that is easy to clean. The acrylic and solid surface build supports this deep, relaxing experience.

Frequently asked questions
Which bathtub material is lighter for easier installation?
Stone resin is significantly lighter than cast iron. The ANZZI stone resin model weighs 77.2 pounds, making it manageable for freestanding placement. Cast iron options like the Kohler Villager weigh 316 pounds. The heavy weight of cast iron often requires reinforced floor framing. You should check your floor load capacity before choosing cast iron.
Does stone resin hold heat as well as cast iron?
Both materials retain heat effectively due to their dense construction. Cast iron is known for its thermal mass, keeping water warm longer. Stone resin also offers good insulation properties while being thinner. The ANZZI tub features a flat bottom that supports stable heat distribution. You will enjoy warm soaks with either material choice.
Which tub fits better in a small bathroom?
The stone resin ANZZI tub is better for tight spaces. It measures 58.9 inches long and 29.1 inches wide. Its freestanding design does not need three walls for support. The cast iron Kohler model is a 60-inch alcove tub. It requires specific wall framing and is larger in footprint. You have more layout flexibility with the stone resin option.
Are both materials resistant to chipping and scratches?
Yes, both stone resin and cast iron are durable against daily wear. Cast iron has a glass-like enamel surface that resists chips. Stone resin composites also offer a glossy, hard finish. The ANZZI tub maintains its Ribbed White appearance over time. The Kohler tub provides a simple, clean white apron design. Both withstand regular use without significant cosmetic damage.
Can I install a stone resin tub without wall support?
Yes, freestanding stone resin tubs do not need wall support. The ANZZI tub stands independently on its flat bottom. This design allows placement in the center of a room. Cast iron tubs like the Kohler Villager are alcove models. They require installation against three walls for stability. You must choose the installation style that matches your bathroom layout.
What is the difference in water capacity between these tubs?
Cast iron tubs often hold more water due to their deeper design. The Kohler Villager holds 30 to 40 gallons. Stone resin soaking tubs vary in capacity based on internal depth. The ANZZI tub is designed for soaking but has a lower profile. You should check the internal dimensions to estimate your preferred water volume for a comfortable soak.
