They are available in a variety of sizes, shapes, and materials, catering to different bathroom layouts and design preferences.

Standard prefabricated shower pans

Prefabricated square shower pans typically start at 30-by-30-inches and can go up to 42-by-42-inches. You may also find larger square pans measuring 60-by-60-inches. Rectangular shower pans can be as small as 32-by-42-inches or as large as 60-by-42-inches. The smallest shower pan for a small square shower is 30 inches. Corner shower pans are measured based on the length of their sides, with prefabricated options ranging from 32 to 36 inches. Neo-angle shower pans have a cross-dimensional measurement between 36 and 60 inches.

Shower pans are commonly made from four different materials: fiberglass, acrylic, solid surface, and tile. Fiberglass shower pans are budget-friendly, lightweight, and stylish. However, scratches may be more visible on the finish, and the finish may become challenging to clean once stained. Acrylic shower pans are lightweight and easy to clean, with the colour running through the material, making scratches less visible. Acrylic is more expensive than fiberglass and requires careful selection of cleaners to avoid surface damage. Solid-surface shower pans are sturdier than acrylic or fiberglass and more resistant to stains from cleansers.

Custom-sized shower pans

Shower pans, also known as shower bases, are available in a variety of standard sizes and materials. However, if you have specific requirements or a unique bathroom layout, you can opt for a custom-sized shower pan.

Tile Redi also provides custom shower pans built to customer-provided specifications, allowing you to choose the shower size, drain style and location, and the number and placement of curbs and entrances.

When considering a custom-sized shower pan, it is essential to take accurate measurements. The threshold of a shower pan determines its depth, with standard thresholds ranging from 1 to 6 inches, while zero-entry showers have no threshold. The width of the threshold depends on the width of the shower and can be as narrow as 30 inches or wider for custom showers. Additionally, ensuring that the distance from the drain centre is measured accurately will guarantee proper water drainage.

Shower pan materials

Shower pans, also known as shower bases, are available in a variety of materials, each with its own advantages and disadvantages. Here is a detailed guide to help you choose the right material for your shower pan:

Fiberglass

Fiberglass is a popular choice for shower pans due to its affordability and lightweight properties. It offers a stylish option without sacrificing your budget. The colour of a fiberglass shower pan is in the finish, making scratches more visible. Over time, the finish may become challenging to clean due to staining. Fiberglass is also known to discolour and stain easily. Fiberglass shower pans typically last for eight to ten years.

Acrylic

Acrylic shower pans are formed over a fiberglass base, resulting in a lightweight and easy-to-clean product. Since the colour runs through the material, scratches are less noticeable and can be buffed out. Acrylic is generally more expensive than fiberglass and requires careful selection of cleaning products to avoid permanent damage. Acrylic shower pans are expected to last for about ten years.

Solid Surface

Solid-surface shower pans offer superior stain resistance compared to acrylic or fiberglass options. This material is known for its grout-free construction, making it easy to clean and maintain. It also does not harbour bacteria. Solid surface shower pans provide a wide range of colour options to choose from.

Tile

Tile shower pans can be built from scratch or using a precast base. Tiles used for shower pans should be slip-resistant. This option is attractive to those who desire more control over the overall design of their shower. While tile shower pans can be budget-friendly, they present the challenge of keeping the tile grout clean, and regular resealing is necessary.

Cast Iron

Cast iron shower pans, such as those offered by Kohler, are known for their durability and longevity. However, they are extremely heavy, weighing over 200 pounds. This weight may require reinforcement of the bathroom floor to support it.

When selecting a shower pan material, it is essential to consider factors such as durability, maintenance, aesthetics, and budget. Each material has unique characteristics that cater to different needs and design preferences.

Shower pan shapes

Shower pans, also known as shower bases, are available in a variety of shapes and sizes. The size and shape of your bathroom will impact the shower pan you choose. For instance, small bathrooms may benefit from neo-angle or corner showers with smaller shower pans to maximise space.

Prefabricated square shower pans are typically the most common, with sizes starting at 30-by-30 inches and going up to 42-by-42 inches. Larger sizes of 60-by-60 inches are also available. Rectangular shower pans can be as small as 32-by-42 inches and as large as 60-by-42 inches.

Corner showers are another option, often used to save space in a bathroom. Corner shower pans are measured by the length of their sides, with prefabricated options ranging from 32 to 36 inches. Neo-angle shower pans are also designed for corner showers, with a unique shape that looks like a sliced-off corner. The shower door glass and the wall meet at a 135-degree angle, while the back corners have 90-degree angles. Neo-angle shower pans have a cross-dimensional measurement between 36 and 60 inches.

Shower pans can also be customised to fit your specific needs and space. Custom shower pans can be made in various shapes and sizes, with options for different drain locations and wall designs.

Shower drain position

Shower pans, also known as shower bases, are the floor of a stand-alone shower. They are available in a variety of sizes, shapes, and materials. The size and shape of your bathroom will impact the size and type of shower pan you choose. For example, small bathrooms may benefit from neo-angle or corner showers with smaller shower pans to maximise space.

When selecting a shower pan, it is important to consider the position of the shower drain. Shower pans can have an offset drain, a centre drain, or an on-edge drain. The position of the drain will depend on the location of the joists and the size and shape of the shower pan. For example, a centre drain may be simpler to install for a tile shower, but it may force the user to stand on the drain, which can be uncomfortable and lead to clogging issues.

To avoid these issues, some recommend locating the drain 12 inches from the shower head wall and centring it from side to side. This keeps the user from standing directly on the drain and minimises the risk of pools of water forming when the drain gets clogged.

Additionally, it is important to be mindful of the threshold of the shower pan, which dictates its depth. The standard height of a shower pan threshold is 4 inches, but it can range from 1 to 6 inches. Zero-entry showers do not have a threshold. The width of the threshold will depend on the width of the shower, typically ranging from 30 to 60 inches.

When purchasing a shower pan, it is critical to find out where your joists are and to measure the distance from the drain centre to ensure proper water drainage. Making adjustments to the drain location may be necessary, even if you are purchasing a standard-sized shower pan.
