When you’re comparing common bathtub materials and starting to select the right bathtub for your home – it can feel like a serious process. You likely have a specific size, style and color in mind that will perfectly complement your style and fulfill your bathing needs.
Before making your decision, consider this other important factor: the materials the bathtub is made with. Material affects appearance, durability, heat retention and more, so it’s a significant factor in your long-term investment.
Here are the nine common materials used in bathtubs:
- Fiberglass
- Porcelain over steel
- Acrylic
- Cast iron
- Solid-surface
- Cast polymer
- Ceramic tile
- Stone
- Wood
We’ll cover the pros and cons of each one, and by the end, you’ll be armed with the information you need to choose the best bathtub for your home.
1. Fiberglass
Fiberglass is easy to install and maintain, but is among the least durable of bathtub materials.
Made of a fiberglass-reinforced plastic (FRP), bathtub fiberglass is layered into the tub’s shape and then coated with resin.
Pros:
- Inexpensive
- Lightweight
- Easy installation
- Easy maintenance
- Repairable surface
Cons:
- Thin/flexible
- Unstable feel
- Surface fading/discoloration
- Surface crack/scratch
- Porous and brittle
2. Porcelain Over Steel
Porcelain over steel is long-lasting and affordable, but it’s also heavier than fiberglass or acrylic and prone to rusting and chipping.
People often compare an acrylic vs steel tub. Both are durable and relatively affordable.
Also called enameled steel, this common bathtub material combination is a sheet of steel coated with porcelain enamel.
Pros:
- Inexpensive
- Long-lasting
- Stable feel
- Easy cleaning
- Standard sizes
- Chemical-resistant finish
Cons:
- Limited design options
- Surface chipping
- Somewhat heavy
- Exposed steel rusting
- Heat loss
- Sometimes noisey
3. Acrylic
Acrylic tubs are a durable material that comes in plenty of design options, but it is a little more expensive than fiberglass or enameled steel and can scratch with the use of certain cleaners.
In an acrylic bathtub, acrylic sheeting is molded into shape and reinforced with fiberglass for a strong, waterproof surface. It’s really one of the most common bathtub materials.
Pros:
- Not water-absorbent
- Retains heat
- Easy installation
- Design variation
- Lightweight
- Easy repair
- Relatively affordable
- Durable
Cons:
- Slightly unstable feel
- Surface scratching
- Chemical sensitivity
- Lacks high-end appearance
4. Cast Iron
Cast iron is durable, efficient and classic. It’s also quite heavy and expensive. Cast iron tubs are a true investment.
When comparing an acrylic versus cast iron tub – you’ll often hear people discuss durability.
Cast iron tubs are made by pouring molten iron into a mold and covering that with thick, enameled porcelain, meaning a cast iron tub is going to last a long, long time.
Pros:
- Durable
- Scratch/chip resistant
- Retains heat
- Design variation
- Resurfaceable
- Classic look
Cons:
- Extremely heavy
- Require additional support
- Expensive
5. Solid Surface
Solid surface materials are relatively new to the bathtub market. They are becoming one of the more common bathtub materials. They are durable and efficient, but also heavy and relatively expensive. Due to the newness of solid surface materials, it may be harder to find information or even place an order.
Comprising synthetic, polymeric materials, solid-surface bathtubs are available in a wide range of design types.
Pros:
- Design variation
- Durable
- Retains heat
- Repairable finish
- Natural-look options
Cons:
- Heavy
- Expensive
- Hard to get
6. Cast Polymer
Cast polymers, such as cultured marble, granite, or onyx, are relatively affordable and easy to maintain, but they can be brittle (slightly better than fiberglass) and develop cracks that can’t be prepared.
The components involved in cast polymer include engineered natural stone and solid surface materials, such as limestone and resin. Typically, the materials are finished with a gel coat on top.
Pros:
- Often affordable
- Design Variety
- Buffable surface
- Easy cleaning
- Stain-resistant
- Relatively durable
Cons:
- Can be expensive (cultured marble)
- Sometimes brittle
- Unrepairable cracks
7. Ceramic Tile
Ceramic tile offers the widest range of design and size options (thus, also price options), but it is relatively high-maintenance. Further, the unevenness of multiple, individual tiles and grout could be uncomfortable on bare skin.
Available in all shapes, sizes and colors, individual ceramic tile will need to be laid on a prepared surface with appropriate mortar and grout.
Pros:
- Design variety
- Can be inexpensive
Cons:
- Complex installation
- High maintenance
- Can be uncomfortable
- Can be expensive
8. Stone
Stone tubs have a high-end appeal and are a great investment, but they are extremely heavy and may require extra structural support and maintenance.
Your natural stone options may include granite, onyx, marble, basalt, sandstone basalt and travertine.
Pros:
- Natural look
- Custom-ordered
- Sturdy
- High-end investment
Cons:
- Very heavy
- Extra support required
- High-maintenance
9. Wood
Wood bathtubs are unique, attractive, and customizable, but can cost a lot and require a great deal of maintenance.
Some of the woods you may select for a bathtub include African or Honduran teak, walnut, ash, cherry, and maple.
Pros:
- Natural look
- Custom ordered
- High-end investment
Cons:
- Expensive
- High-maintenance
