The Manufacturing Process 

The manufacturing process for acrylic tubs is quite simple but it is more hands on than fiberglass. A sheet of acrylic is heated up to about 200 degrees, it is then sucked by vacuums into a mold and then cooled by fans. Once the mold of the tub is finished it is then reinforced by a thick layer of fiberglass. Once the fiberglass is layered it is then laminated with rollers that remove all air bubbles which could weaken the tub and allows the fiberglass to stick to acrylic perfectly. The drains and any other holes are then cut to the precise specifications.  

Fiberglass tubs are made by heating up thin layers of glass strings so that they bind together. Once the binding process is completed the layer of Fiberglass is then molded and shaped and sprayed with resin to hold the shape. Fiberglass tubs are quite easy to manufacture because it does not take a significant number of steps or materials to complete.  

The Differences Between Fiberglass & Acrylic Tubs 

The main differences between fiberglass and acrylic tubs are the manufacturing process; usually fiberglass is an easier process and does not cost as much as acrylic to manufacture. Acrylic tubs can come with more customizable options including textures, colors, and fixtures. Also, acrylic is much more durable than fiberglass because of the fiberglass coating that surrounds the bottom. DaBella offers top of the line nonporous acrylic bathtubs and shower pans for their reliability, durability, and minimal maintenance qualities.   

What is different about fiberglass is that the manufacturing and installation is slightly cheaper than acrylic. But you will not be able to get the durability of acrylic. Also, Fiberglass tubs do tend to involve much more maintenance because they can shift and will get scratched, crack and will need to be refinished at some point during their lifetime.  

The Similarities Between Acrylic & Fiberglass Tubs 

Both fiberglass and acrylic are fiberglass-based materials but the shell of acrylic is different than fiberglass. Both materials are quite easy to install and do not involve a lot of labor. Fiberglass and acrylic baths are sometimes installed in one day. Both materials are very affordable, and you will not break the bank paying for either. Both require regular weekly to monthly cleaning to preserve their pristineness. You will need to pay regular attention to fiberglass tubs as they are prone to staining. You can clean both with just about any kind of cleaner you find in the store that will not scratch or damage your new tub.  

Maintenance Differences 

Both acrylic and fiberglass are amazingly easy to maintain. What DaBella recommends you use to clean your acrylic tub would be either Fantastic, Windex, Tilex spray, 409 spray, Lime Away spray, Fabuloso, Green Works, Spic & Span spray, Pine Sol, or Simple Green. You do not want to use any abrasive or gritty cleaners on your acrylic tub including Scotch Brite Pads, Magic Eraser, Comet Power or any solvents and thinners.  

Fiberglass tubs do tend to have more maintenance involved because the layer of coating is prone to scratching and cracking. Also, fiberglass tubs do tend to lose their color after a few years so they will need to be refinished every few years to keep them pristine. Fiberglass tubs are also prone to shifting and bending because it is a flimsy material. This can inevitably make the caulking around the tub to crack allowing water to seep through which will cause problems in the future if not taken care of.  

Are Acrylic or Fiberglass Tubs Best for Your Next Bath Remodel?  

Trying to figure out what looks best, what will hold up the longest and is within your budget can be a difficult decision. At DaBella we recommend you go for a material that will go the distance and be easy to maintain. Acrylic is undoubtedly the best material for your home for its lightweight qualities, durability, and undemanding maintenance.  

FAQ’s: Acrylic vs Fiberglass Tubs

Our most frequently asked questions regarding homeowners deciding between acrylic and fiberglass tubs:

Are all baths acrylic now?

No, not all bathtubs are acrylic, though acrylic has become the most common material in modern residential construction due to its affordability, lightweight nature, and ease of installation. The market still offers a wide range of materials including fiberglass, cast iron, steel enamel, porcelain-enameled steel, and stone resin. Acrylic dominates new home builds and remodels because it’s inexpensive to manufacture, comes in virtually any shape or size, and is relatively easy to repair — but higher-end bathrooms still frequently feature cast iron or stone resin tubs for their premium feel, superior heat retention, and longevity.

What’s the best material for a bathtub?

For most homeowners, acrylic strikes the best balance of cost, comfort, and practicality. It’s lightweight, warm to the touch, available in countless shapes and styles, and significantly easier to install than heavier alternatives. High-quality, reinforced acrylic tubs resist flexing underfoot, hold up well against everyday use, and can be repaired with DIY kits if scratched or chipped — something cast iron and stone resin can’t offer as easily. While cast iron and stone resin outperform acrylic in heat retention and raw durability, acrylic remains the most well-rounded choice for the average bathroom renovation or new build.

What bathtubs do plumbers recommend?

Plumbers and home improvement contractors generally favor reinforced acrylic tubs for most residential installations because they’re lightweight, easy to maneuver into place, and put minimal stress on floor structures and drain fittings. The key distinction plumbers emphasize is thickness and backing — a quality acrylic tub should feel solid and rigid underfoot with no flexing, as thin acrylic will crack around the drain and overflow fittings over time, leading to leaks and costly repairs. Plumbers typically steer homeowners away from the cheapest acrylic options and toward mid-to-upper-grade reinforced models, noting that a little more spent upfront on a thicker, sturdier tub saves significantly on service calls down the road.

What type of tub lasts the longest?

Cast iron lasts the longest overall, often 50–100 years or more, but among acrylic tubs, lifespan varies significantly based on quality and care. A well-made, reinforced acrylic tub can last 15–20 years or longer when cleaned with non-abrasive products, never exposed to harsh chemicals, and promptly repaired when scratched or chipped. The biggest enemies of acrylic longevity are abrasive cleaners that dull and weaken the surface over time, heavy impacts that cause cracking, and neglected chips that allow water to penetrate beneath the surface. With proper maintenance — gentle cleaning, periodic polishing, and protective waxing — a quality acrylic tub can remain in excellent condition well beyond its average lifespan.
