Shower Fiberglass: Is It Safe Or A Health Risk?

Fiberglass showers are a popular choice for homeowners due to their affordability, durability, and ease of installation. However, fiberglass showers have their drawbacks, including sensitivity to extreme heat and corrosion from certain cleaning products. Additionally, fiberglass manufacturing is energy-intensive and can release toxic air pollutants. This raises the question: does fiberglass in showers contribute to fiberglass pollution, specifically in aquatic environments? Fiberglass is known to be a pollutant in water when it makes up the hulls of boats, but what about in the smaller quantities that may come from shower use and maintenance?

Fiberglass showers: pros and cons

Fiberglass showers are a popular choice for homeowners due to their affordability and ease of installation. They are also known for their durability and resistance to moisture and stains. However, fiberglass showers have their pros and cons, and it is essential to consider these before making a purchase decision.

One of the main advantages of fiberglass showers is their cost-effectiveness. Fiberglass shower pans or enclosures are typically cheaper than those made from other materials, such as acrylic or ceramic. This makes them an attractive option for those looking to remodel their bathrooms on a budget. Additionally, fiberglass showers are relatively easy to install, with some models even offering DIY installation, saving on labor costs.

Fiberglass showers are also known for their design versatility. They come in a wide range of styles, colors, and shapes, making it easier to find an option that complements the existing bathroom color scheme and layout. Fiberglass showers can also be customized to include features such as built-in shelves, storage areas, and level-access floors, making them more accessible for individuals with limited mobility.

However, one of the significant disadvantages of fiberglass showers is their susceptibility to damage. Fiberglass is a delicate material that can be easily scratched, chipped, or cracked if not handled or cleaned properly. Harsh cleaning products, such as bleach or ammonia, can damage the glossy finish of fiberglass surfaces. Repairs to fiberglass showers can be challenging and may not always result in a seamless finish. Therefore, damaged enclosures may need to be replaced entirely, increasing the overall cost of ownership in the long run.

Another consideration is the maintenance required for fiberglass showers. While they are relatively low-maintenance compared to other options, proper care is needed to maintain their appearance and hygiene. Fiberglass showers should be cleaned regularly, at least once a week, to prevent the buildup of dirt, stains, and soap scum. Special scratch-proof cleaners are available for fiberglass surfaces, and it is important to avoid using abrasive tools or harsh chemicals that can damage the finish.

In conclusion, fiberglass showers offer a cost-effective and design-flexible option for homeowners. However, the potential for damage and the need for careful maintenance should be carefully weighed against the benefits. For those seeking a long-lasting and low-maintenance option, other materials like acrylic may prove to be a more suitable investment despite their higher upfront cost.

Cleaning and maintaining fiberglass showers

Fiberglass showers are durable and cost-effective, but they can quickly become dull due to soap scum and other stains. Here are some tips for cleaning and maintaining your fiberglass shower:

Regular Cleaning

To prevent the buildup of dirt and stains, it is recommended to clean your fiberglass shower at least once a week. Start by removing all bottles, soap, razors, and accessories from the shower. Then, rinse away any loose dirt and debris with warm water to ensure that you do not accidentally grind dirt into the surface of the shower.

Ventilate the Area

Before applying any cleaning products, open the bathroom door and turn on the exhaust fan to prevent fumes and moisture from building up.

Choose the Right Cleaning Products

Avoid using harsh cleaners, such as bleach or ammonia, on fiberglass surfaces as they can damage the material. Mild dish soap, glass cleaner, or a mild all-purpose cleaner, like Mr. Clean Clean Freak Mist, are suitable options. White vinegar is also a safe and effective cleaner for fiberglass. It can be used on its own or mixed with a few drops of mild dish soap for extra cleaning power. If using vinegar, it is best to test it in an inconspicuous area first to ensure it doesn't damage the finish.

Apply the Cleaner

Apply the cleaning solution to the shower surfaces using a sponge, cloth, or soft-bristle brush. Pay special attention to areas with thicker grime. Avoid using hard-bristle brushes, scouring pads, or metal pads, as they can scratch the fiberglass.

Rinse and Dry

After allowing the cleaning solution to work for a few minutes, rinse the shower with clean, warm water to remove the solution and grime. Dry the shower thoroughly with a towel or squeegee to prevent the growth of mold and mildew.

Address Stains and Discoloration

For tough stains, such as rust or stains caused by bath products, create a paste of laundry borax and lemon juice. Spread the mixture on the stained area, allow it to work for 15 minutes, then wipe it away with a microfiber cloth. Rinse the area well and buff it dry. If your fiberglass shower has turned yellow due to exposure to UV rays, use a commercial cleaner specifically designed for fiberglass to remove the discoloration.

Repair Cracks

If you notice any cracks in the fiberglass, repair them promptly to prevent further damage. Use a fiberglass repair kit to fill the cracks and restore the integrity of the floor.

Prevent Mold and Mildew

To prevent the growth of mold and mildew, improve ventilation by using the exhaust fan during and after showering. Open a window if possible, or consider using a dehumidifier if ventilation is poor. Empty and clean shower caddies or nooks regularly, as these tend to harbor mold and mildew. Once your shower is clean, you can apply a coat of fiberglass boat wax to the walls to allow water to run off without spotting. Do not apply wax to the floor, as it can become slippery.

Fiberglass as an aquatic pollutant

Fiberglass, also known as glass fiber or fiber-reinforced plastic, is a composite material made from plastic resin (usually polyester, vinyl ester, or epoxy) and glass fibers. It is commonly used in construction and aquatic applications due to its strength, lightweight nature, flexibility, water resistance, and durability. However, these same qualities that make fiberglass useful also contribute to its impact on the environment, particularly as an aquatic pollutant.

Fiberglass is an often-overlooked contributor to water pollution. Abandoned and derelict vessels made of fiberglass can break down in water, causing significant harm to aquatic ecosystems. The durability of fiberglass makes it challenging to dispose of when products are no longer wanted or functional. As a result, many fiberglass products, such as boats, are abandoned or dumped, ending up in coastal areas, lakes, and rivers. Over time, these derelict vessels break down, releasing fiberglass into the water.

Fiberglass also becomes a water pollutant when it makes up the hulls of boats. As hulls scrape against rocks or the sandy bottoms of lakeshores, or as paint flakes off, microscopic shards of fiberglass shed into the water. In 2018, a centuries-old oyster fishery in England experienced a massive die-off, which researchers traced to this type of microplastic pollution. Each kilogram of oyster meat examined contained up to 7,000 shards of fiberglass.

Additionally, the manufacturing process of fiberglass contributes to its impact as an aquatic pollutant. Manufacturing fiberglass is energy-intensive and relies on fossil fuels, which can release toxic air pollutants such as styrene, VOCs, and smog. These pollutants have the potential to affect both the environment and the health of nearby communities.

To address the issue of fiberglass aquatic pollution, it is essential to explore alternative materials for boat hulls and other aquatic applications. While materials like wood, steel, aluminum, and polyethylene have their advantages and disadvantages, emerging options like bio-based plastics and basalt fiber offer more sustainable choices for hull construction. By transitioning to more environmentally friendly materials and improving the responsible disposal of fiberglass products, we can mitigate the impact of fiberglass as an aquatic pollutant.

Fiberglass vs. acrylic showers

Fiberglass and acrylic are two popular options for shower materials. They are both lightweight, low-cost alternatives to ceramic or stone tiles. While there are many similarities between the two, there are also some key differences to consider when choosing which material is best for your bathroom.

Acrylic showers offer a wide variety of texture, colour, and fixture options. They are made from large sheets of customizable acrylic that are heated, stretched, and pulled over a large mould, usually made of aluminium. Once the acrylic shell is removed from the mould, it is reinforced with fiberglass resin. Acrylic is considered a type of plastic that has the look of glass but is safer and more flexible. Acrylic shower pans are built to last through thousands of showers, tons of pressure, and the daily abuse of sprayed water and abrasive soaps, hair and cleaning products. They are completely water-resistant and will not corrode over time, and scratches are rarely seen. Acrylic is also commonly used for other parts of the shower, such as the door, enclosures, or fixtures. However, if the acrylic does become damaged, repairs can be complicated and costly. Acrylic is also generally more expensive than fiberglass.

Fiberglass showers are made in a similar way to acrylic showers, but instead of vacuuming acrylic over a mould, a layer of polyester gel coat is sprayed onto an open mould. Once the gel coat cures, it is reinforced with fiberglass resin. Fiberglass showers are extremely durable, but they are more likely to crack or break. They are also more commonly used for fitting showers into inconvenient locations and shapes, and shower additions such as seats are commonly made with fiberglass. Fiberglass is sensitive to extreme heat and can corrode with frequent use of cleaning products, especially acidic ones. It can also be a breeding ground for bacteria if there are corners in odd places. Fiberglass is generally cheaper than acrylic and is easier and more affordable to repair or replace if it becomes damaged.

Both materials require regular cleaning to prevent the buildup of dirt and stains. It is recommended to clean your fiberglass or acrylic shower floor at least once a week. Avoid using harsh cleaners such as bleach or ammonia, as these can damage the material. Mild cleaning solutions or commercial cleaners specifically designed for fiberglass or acrylic surfaces are best.

Alternatives to fiberglass

Fiberglass is a popular choice for showers due to its affordability, ease of installation, and durability. However, it has some drawbacks, including the potential for cracking or breaking, sensitivity to extreme heat, and corrosion with certain cleaning products. Additionally, fiberglass can be a breeding ground for bacteria if there are corners in odd places. As such, it is important to consider alternatives that can provide similar benefits without these issues.

One alternative to fiberglass is acrylic. Acrylic shower pans are made by heating, stretching, and moulding acrylic sheets. They are lightweight, easy to install, and highly durable. Acrylic is also water-resistant and less likely to scratch or corrode compared to fiberglass. While acrylic is generally more expensive than fiberglass, it offers greater strength and flexibility.

Another option is to use ceramic or stone for the shower. These materials offer a wide range of customisation options and are known for their durability and longevity. However, they tend to be more expensive and time-consuming to install, especially for DIY enthusiasts. Tile showers, for example, require regular maintenance of grout lines to prevent mildew, cracking, and leaking.

Prefabricated shower stalls are also available, typically made of fiberglass or acrylic. These showers are considerably lighter than custom tile showers and can be installed by professionals or experienced DIYers. They offer a variety of styles and are more affordable than tiled showers, with prices ranging from $400 to $2,000.

For those seeking a unique design or a specific shape for their shower, mating a fiberglass or acrylic shower pan with tile walls could be an option. This combination provides flexibility and durability, ensuring that the shower pan will not crack if there is some flex in the subfloor.

Ultimately, the best alternative to fiberglass depends on individual needs, preferences, and budget. While acrylic and prefabricated showers offer ease of installation and affordability, ceramic or stone showers provide durability and customisation options.
