Why Choosing the Right Bathtub Material Matters

(and How It Can Make or Break Your Daily Ritual)

You’re about to spend thousands on a new bathtub. You’ve fallen in love with the shape, the depth, the Instagram-worthy photos. But here’s the truth most showrooms won’t tell you: The material is more important than the design.

Get it wrong, and in two years you’ll be dealing with scratches, stains, yellowing, or a tub that feels cold the second you step in. Get it right, and your bathtub will look and feel brand new for 15–20 years — while giving you the exact experience you paid for.

Here’s your no-nonsense guide to the most popular bathtub materials in 2025 and the honest pros and cons of each.

1. Acrylic – The Smart Default (Most Popular Choice)

• Warm to the touch (insulates heat beautifully)
• Lightweight and easy to install
• Glossy, non-porous surface — resists stains and mold
• Can be repaired if scratched
• Huge variety of shapes, colors, and price points

Best for: Japanese deep-soaking tubs, freestanding sculptural designs, and 99 % of luxury renovations under $8,000.

2. Solid Surface (Corian, Krion, etc.) – The Premium All-Rounder

• Seamless, matte or satin finish
• Completely renewable — scratches can be sanded out
• Warm feel, excellent heat retention
• Available in matte black, concrete-look, or custom colors

Best for: Modern minimalist bathrooms and anyone who hates visible seams.

3. Cast Iron with Enamel – The Classic That Never Dies

• Unmatched heat retention (water stays hot for 45+ minutes)
• Incredibly durable enamel surface
• That satisfying “thud” when you knock on it

The catch: Weighs 350–500 lbs — your floor may need reinforcement.

Best for: Traditional clawfoot tubs and people who value heritage over trends.

4. Natural Stone (Marble, Granite, Travertine) – Pure Drama

• One-of-a-kind veining
• Feels luxurious and cool in summer

The reality: Porous (needs sealing every year), heavy, expensive, and stains if you use bath bombs.

Best for: Statement pieces in homes that already have a full-time housekeeper.

5. Copper – The Antimicrobial Showstopper

• Naturally kills bacteria and viruses
• Develops a beautiful living patina over time
• Amazing heat conductivity

Downside: Price tag starts at $10,000+ and it will change color (some love it, some don’t).

Best for: High-end boutique hotels and homeowners who want something no one else has.

6. Enameled Steel – Budget Option (Avoid Unless You Must)

• Cheap and lightweight
• Chips and scratches easily
• Feels cold and “tinny”
