Fiberglass can easily bend under weight because it is very flexible. Improper support and pressure from frequent use and harsh cleaning detergents can cause cracks after some time. Also, dropping heavy objects in the bathtub can cause dents and small divots.
Finding cracks in your fiberglass shower pan is more common than you think. There isn't a week that goes by that we don't get at least one call regarding fiberglass shower pan cracks. The main cause for these cracks is poor installation. Some installers do not put the correct amount of support under the pan.
They're attractive tubs that are easy to install and repair. However, they are also prone to damage if you aren't careful. Specifically, they can become cracked or chipped, which damages their appearances and can undermine their structural integrity.
Besides cracks and holes, there are other common issues that plastic (fiberglass or acrylic) tubs or showers encounter, like chips, scratches, stains, discoloration, and dull surfaces, among others.
Because of its laminar layup structure, fiberglass is potentially subject to cracking parallel to the surface, either because of applied stresses or weaknesses resulting from manufacturing anomalies.
Showers made of prefabricated fiberglass or acrylic usually last up to 10 years. Also, prefabricated pans tend to develop stubborn, yellow stains over time. Tubs: Cast iron remains one of the most durable, robust bathtub materials today.
Glassfiber insulation is made from strands of glass fiber and temporarily loses its thermal resistance when it gets wet. However, if it can dry out and has not become compacted, it will retain its insulating properties. Wet insulation in a closed wall cavity will usually not rapidly dry out.
Bottom line is that acrylic is a stronger material than fiberglass. Acrylic tubs effectively resist wear and tear for years on end, while fiberglass is prone to scratching and cracking. Fiberglass also fades more quickly, especially if exposed to sunlight coming in through a window.
Restore Your Fiberglass Shower with Repair & Reglazing
Don't cover up a stained fiberglass shower or bathtub with an insert! You can make your tile or fiberglass shower like new with professional refinishing for a fraction of the cost.
Diagnosing “Spider Cracks” in Fiberglass
Since these cracks often form from small impacts or minor flexing, they can appear just about anywhere on your boat. And if there's not too much discoloration, you can sometimes completely fail to see these cracks from afar.
Be careful not to use any abrasives on the fiberglass, such as scouring pads, steel wool or gritty cleaning solutions. “Soft Scrub” may be used sparingly on soap scum buildup. “Lime-Away” may be used for hard water mineral deposits.
Eyes may become red and irritated after exposure to fiberglass. Soreness in the nose and throat can result when fibers are inhaled. Asthma and bronchitis can be aggravated by exposure to fiberglass. Temporary stomach irritation may occur if fibers are swallowed.
Continual exposure to elevated temperatures reduces the strength of plastics and glass reinforced fiberglass.
Durability. Ceramic tile is one of the most durable materials you can choose for your shower. It will stand the test of time against daily wear and tear, and with the right grout and regular care, ceramic tile will be fairly low maintenance.
Replacing a fiberglass shower stall with tile costs $800 to $2,600 on average, depending on the tile material, tile pattern, and shower size. Removing the fiberglass shower stall costs $70 to $400, including hauling away the debris. Adding a tiled shampoo niche, shelf, or bench costs $200 to $500 more.
Converting a tub to a shower typically costs $1,200 to $8,000, with an average price of $3,000. * We'll go over various cost factors and other tips for the project in our guide.
The good news is that leakage from a shower pan is damage that is usually covered by your homeowner's insurance policy. However, you should act quickly when you suspect a leak, to make sure you don't miss reporting deadlines in your insurance contract.
Does home insurance cover damage from water escaping from my shower recess/shower base? No – this is a specific exclusion under most home insurance policies, as a correctly constructed and maintained shower recess or base will not allow water to escape.
The leaking from the pan likely caused damage to the base, and you may notice cracks. If you need to replace the base, it'll cost $225 to $650.
High-quality fiberglass boats can last up to 50 years or even more. However, lower quality fiberglass may have cracks, blisters, or irregularities; these can begin to show after a few years of use.
Fiberglass boats are made from a combination of glass fibers and resin. Over time, the resin can break down due to exposure to the elements, such as UV rays from the sun or saltwater. This can cause the boat to become brittle and weak, leading to cracks and other damage.
Vinegar is strong enough to remove tough soap scum stains and hard water deposits. Pour vinegar over the problem area. Allow to sit for several minutes. Then use a fiberglass friendly sponge or brush to scrub the stain.
