There are many different sizes of shower floor pans and bases. These also come in various options, each having a slightly different function from the others. Some have drains set in different locations. Some are tilted, and some are flat. There are many variables you need to consider when purchasing a new shower. All of this can be overwhelming to an inexperienced person. That’s why we’re coming to help you- in this article, you’ll learn all about the different types and sizes of shower trays. You will also see some actual products and their typical prices. Let us begin!
What is the difference between a shower pan and a shower base?
First, we need to clarify the differences between those two terms to learn about shower pans and bases. Although they’re used interchangeably, they are not exactly the same thing. They possess different qualities and characteristics, and different variables must be considered when looking for the best one.
What exactly is a shower pan?
A shower pan is a part of the installation that we stand on. It’s visible, and it’s right underneath our feet when we take a shower. It serves a similar main purpose to a shower base. It takes the water to the drain. However, the difference comes in the fact that:
- You can see the shower base
- You stand on it and feel it with your body.
Because of these two aspects, these parts are usually made of metal, stone, acrylic, or fiberglass. Those are materials that are aesthetically pleasing and safe to stand on. Like the base, it’s designed to be waterproof and keep all the water going where it should.
The installation process is also different in those two elements. The shower pan is installed right above the base. Then, panels from a material such as a fiberglass are installed onto the pan. It makes it a full shower. In this case, the visual aspect is much more important than any other one. When searching for a perfect shower pan, you must be sure that it matches your artistic style.
What is a shower base?
It is a part on the very bottom of a full shower. It’s not exactly a piece, as much as it is a sub-installation. It requires preparation work to function properly and works directly with your house’s plumbing system. It is also the part directly responsible for properly taking the water into the drain. When using the shower, you can neither see nor touch it, as it’s located under the pan.
Considering this part’s characteristics, it’s important to mention that functionality is key to a proper selection. A good shower base doesn’t have to look nice- it won’t be seen either way. It’s made from materials such as cement mortar. It’s a material that’s secure, solid, and waterproof.
Installing a shower base is also different from installing a pan. It has to be installed before anything else because it acts as a foundation for the rest of the shower’s construction. It also requires a direct connection to the house’s plumbing and thus is much harder to connect properly. In the case of shower bases, using an expert’s help is much more common. In most cases, it is also recommended. Installing it incorrectly is much more devastating than failing to install a shower pan. The removal process is much more tedious and demanding. Take into account the nature of the materials it’s made of. Like cement mortar, it’s also much more permanent and sturdy.
Standard sizes of shower trays
Now that we know the differences let’s get to the actual sizes of these shower floors. It’s important to know that shower trays can be further divided into variations based on the drain’s location. These variations are:
- An offset drain, with the drain on the right-center or left-center of the tray
- An on-edge drain, with the drain on either of the edges of the tray
- A center drain, with the drain in the middle of the tray.
Each option has unique standardized models and sizes used across all brands. Typically, center drains are done in a squarer shape. The on-edges and offsets have a more rectangular shape. This distinction is important because it determines the amount of space you need for the shower floor. It includes the exact spot you have to position it in for the drain to be properly aligned. Choosing the wrong size or shape might result in the inability to install the drain according to the plumbing. Therefore, it makes the whole installation pointless.
These parts are installed similarly to how prefab buildings are assembled- premade pieces are put together. It starts with the bottom, going up with the walls, and then the finishing.
Most of the size models of these pieces are made in even measurements. It typically ranges from 36 inches by 36 inches to 42 inches by 60 inches.
Here are the sizes, categorized by tray model, along with some available pieces:
