Did You Know?

1. Shower pans are typically made of a material called fiberglass-reinforced plastic (FRP), which is a composite material made by combining layers of fiberglass with a plastic resin. This makes the pan lightweight, durable, and resistant to water damage.

2. Some high-end shower pans are made of solid surface materials, such as cultured marble or engineered quartz. These materials offer a more luxurious and visually appealing look, but they tend to be more expensive than traditional FRP shower pans.

3. One lesser-known material used for shower pans is cast iron. Cast iron shower pans were popular in older homes, as the material is known for its durability and heat retention properties. However, cast iron pans can be quite heavy and may require additional structural support.

4. In the past, shower pans were also made from lead. However, due to health concerns associated with lead exposure, the use of lead-based materials has been phased out and is now banned in many countries.

5. Some shower pans are made using a combination of different materials. For example, a shower pan may have a base made of FRP and a top layer made of tile or stone. This allows for a more customizable and visually appealing design while still benefiting from the durability and water resistance of FRP.


Acrylic shower pans are durable and versatile, which makes them a popular choice for modern bathrooms. These pans are made from polymethyl methacrylate (PMMA), a type of plastic. What sets acrylic shower pans apart is that they are lightweight and easy to install and transport. They also have a smooth, non-porous surface that is stain-resistant and easy to clean.

One of the key advantages of acrylic shower pans is their affordability. Compared to materials like custom tile or composite, acrylic pans are more budget-friendly. Furthermore, acrylic is highly malleable, allowing for various design possibilities. It can be molded into different shapes and sizes to suit any bathroom layout.

It’s worth noting that acrylic shower pans have a few limitations too. They may be prone to scratching if not cared for properly, so it’s important to avoid using abrasive cleaners or scrub brushes. Additionally, acrylic is less heat-resistant compared to other materials, so caution should be exercised with hot water and hair styling tools in the shower. However, with regular maintenance and proper care, an acrylic shower pan can last for many years.


Another common material used for shower pans is fiberglass. Fiberglass shower pans are constructed by layering a combination of fine glass fibers and a liquid resin. This creates a strong and durable material that can withstand heavy use.

Fiberglass offers similar advantages to acrylic in terms of cost and installation. It is a lightweight material that is easy to handle and transport. Fiberglass shower pans are also available in various shapes and sizes, allowing for flexibility in bathroom designs.

One of the main benefits of fiberglass shower pans is their resistance to cracking and chipping. The layered construction provides strength and stability, making it less prone to damage compared to other materials. Fiberglass is also a good insulator, helping to retain heat when showering.

However, fiberglass shower pans may require some extra care when it comes to cleaning. The porous surface can be susceptible to staining, so regular maintenance and using non-abrasive cleaners are recommended. Despite this, fiberglass shower pans are a cost-effective option that can provide long-lasting durability.

Custom Tile

For a more luxurious and customized look, many homeowners opt for shower pans made from custom tile. These shower pans are constructed using individual tiles, which are set on a subfloor and then sealed to create a watertight surface.

Custom tile shower pans offer a high-end aesthetic and allow for endless design possibilities. They can be personalized to match the overall bathroom decor, and a variety of tile materials, including ceramic, porcelain, and natural stone, can be used. This versatility allows homeowners to create a unique and visually appealing shower space.

In terms of maintenance, custom tile shower pans require regular cleaning to prevent grout discoloration and mold growth. It’s important to use appropriate tile cleaners and sealers to maintain the look and integrity of the shower pan. While custom tile shower pans may entail a higher initial cost and longer installation time, they provide a timeless and elegant finish that many homeowners desire.

Frequently Asked Questions

What is the best material for a shower pan?

When it comes to selecting the best material for a shower pan, it is crucial to prioritize qualities such as durability, slip-resistance, and load-bearing capacity. One material that meets these requirements is acrylic, which not only offers durability but also comes in a wide range of price points. Another excellent choice is fiberglass, known for its affordability and slip-resistant properties. However, for a more luxurious option, stone serves as an exceptional material due to its durability and aesthetic appeal. Ultimately, the choice of material for a shower pan depends on personal preference, budget, and the desired level of sophistication for your bathroom space.

What is the material under a shower pan?

The material typically used under a shower pan is a bed of mortar. This serves multiple purposes, including providing a sturdy foundation for the shower floor and protecting the subfloor from potential water damage, mold, and rot. The mortar base creates a satisfyingly solid surface, contributing to the overall durability of the shower installation.

What is the most common shower pan?

The most common shower pan is typically made of acrylic or polyurethane. These materials are popular due to their waterproof properties and ability to be easily molded into a one-piece design. Both acrylic and polyurethane shower pans have a sloping design that helps direct water towards the drain, ensuring efficient drainage and preventing water from accumulating on the shower floor. Whether it’s the durability of acrylic or the flexibility of polyurethane, these two materials are commonly preferred for their suitability in creating functional and aesthetically pleasing shower pans.

Is a shower pan better than tiles?

Although tile flooring is often considered more durable than shower pans, there are distinct advantages to using a shower pan. One notable advantage is the ease of installation. Unlike tile flooring, a shower pan can be quickly and easily installed with minimal effort. Additionally, shower pans require less maintenance and are more cost-effective. With a shower pan, you can enjoy a hassle-free, long-lasting showering experience without the high costs and complexities associated with tile installation.
