1. Marble Composite Bathtubs

• Composition: A mix of crushed natural marble and resin.
• Features: These bathtubs mimic the appearance of natural marble, offering a luxurious look with a glossy finish. They have high strength and are often less porous than natural marble, making them more stain-resistant and easier to maintain.
• Pros: Luxurious aesthetics, durable, and often comes with a smooth surface.
• Cons: Still relatively heavy and can be more expensive due to the use of marble.

2. Solid Surface Bathtubs

• Composition: A blend of natural minerals and acrylic or polyester resins.
• Features: Solid surface bathtubs can be molded into seamless designs and come in a variety of colors and finishes. They are easy to maintain, repairable (scratches can be buffed out), and resistant to mold and mildew.
• Pros: Lightweight compared to stone-heavy options, customizable, seamless design, and repairable.
• Cons: May not be as scratch-resistant as stone-based materials, but scratches can be polished out.
