Acrylic vs. Fiberglass Tubs: What Are the Differences?

A white toilet is next to a fiberglass bathtub with chrome fixtures. The flooring is made of black and white diamond tile.

Renovating a mobile home is a lot easier when you know a thing or two about the details of updating a tub. The process starts with deciding which material fits your lifestyle, budget, and decor.

Some materials are durable, and others offer a variety of colors. Not to mention, many materials fall into different cost categories. But how do you decide which is the best fit? For an easy decision-making process, use this guide to understand the differences between acrylic and fiberglass tubs.

What Are Acrylic Tubs?

Manufacturers make acrylic tubs from sheets of acrylic plastic that reinforce the fiberglass. The materials form a tub that is lightweight yet heavy-duty. The glossy, smooth surface is nonporous and resistant to mildew.

Acrylic tubs are available in a range of colors, shapes, and customizable features like whirlpool jets. Plus, their durability and modern aesthetic make them a favorable choice for mobile homes.

What Are Fiberglass Tubs?

But manufacturers create fiberglass tubs using a mix of resin and spun glass fibers, finished with a protective gel coat. They’re lightweight, affordable, and easy to install, making them great for temporary or budget-friendly bathroom upgrades.

Fiberglass tubs provide practical functionality that works well in many households. However, they do not come with as many ways to customize them as acrylic tubs.

Durability Matters

When comparing durability between these two materials, acrylic tubs outperform fiberglass. Acrylic’s surface is scratch-resistant, won’t fade or crack easily, and can handle years of consistent use. This makes it an excellent long-term investment.

Fiberglass is more delicate, since the gel coating can wear away, making the material prone to scratches, cracks, and discoloration. While fiberglass can last for years with diligent care, you may have to replace it sooner than acrylic.

Breaking Down the Costs

Cost is important since you need something that will fit in with your budget, yet last for a while. Fiberglass tubs are typically more affordable. However, you may need to replace the tub sooner than if you had a more durable option, like acrylic. This is something to keep in mind if you are planning on living in your home for a considerable amount of time.

Acrylic tubs are costly, and they only increase in price with every customization. However, their extended lifespan, durability, and low-maintenance costs often make them the most valuable long-term investment.

Which Material Is Easier To Install?

Both acrylic and fiberglass are lightweight materials, making them easy to install. Bathtubs, like cast iron or porcelain, are the heaviest materials, so they’re especially tough to install.

Many homeowners considering DIY bathroom upgrades prefer fiberglass tubs because they’re lightweight. Acrylic tubs are a little heavier than fiberglass, but they don’t require reinforcement or professional setup.

Maintenance and Cleaning

Keeping your bathroom clean shouldn’t feel like a constant chore, and acrylic tubs are easy to maintain and clean. The smooth, nonporous surface resists mold, mildew, and stains, so all it takes is some mild soap and water.

Fiberglass tubs, on the other hand, demand more frequent attention. They’re more prone to absorbing water and developing stains or mildew. Without regular cleaning, the gel coat will deteriorate and require work to keep the tub looking new.

Design Options

A wide, white bathtub with chrome fixtures is in a bathroom with large, tan tiles on the floor and wall.

If style is a must, then an acrylic tub is what you want. From contemporary designs to more traditional looks, they come in many colors, finishes, and shapes. You can also add custom features, like molded seats or textured surfaces, for a luxurious experience.

Fiberglass tubs are simple. They feature basic shapes and minimal design options. While they’re functional, they might not provide a decorative touch for people seeking upscale styles or aesthetics.

How Do They Handle Heat?

For fans of long, relaxing baths, acrylic tubs win in heat retention. The material holds warmth longer, keeping the water comfortable for all your extended soaking times in the tub.

Fiberglass loses heat quickly, cooling the water at a faster rate. If a cozy, warm bath experience is a priority, acrylic is the better choice.

Longevity in Use

With proper care, both tub types can last 10 to 15 years. That said, acrylic’s superior resistance to wear and tear makes it less likely to show its age over the years that you have it in your home.

Fiberglass, while durable, may develop signs of aging sooner, especially in busy households where the tub gets frequent use. Cracks or fading are common issues with older fiberglass tubs, so keep this in mind if you like a clean space, free of wear.

Quick Overview of the Differences Between Acrylic and Fiberglass

Here’s a quick breakdown of the most important distinctions between these two tub materials:

Acrylic

  • Durable and long-lasting
  • A variety of colors and designs available
  • Easy to clean
  • Resists staining
  • Retains heat for prolonged soaks

Fiberglass

  • Affordable
  • Lightweight
  • Easy to install
  • Requires more frequent maintenance
  • Standard style options

Make the Best Choice for Your Mobile Home

Picking between acrylic and fiberglass comes down to their differences. Which one matches your priorities? If affordability and simplicity are important, fiberglass might be the better option. It’s a practical and budget-friendly choice, especially for quick projects or temporary setups.

But if you’re after durability, custom options, and a touch of luxury, acrylic is well worth the extra cost. It can withstand daily use, retain its glossy appearance, and you can add features that can improve the bathing experience.
