Standard Shower Pan Sizes

Standard shower pan sizes have been an integral part of bathrooms. Most homeowners who renovate their bathrooms prefer installing shower pans to gather the water and drain it completely while keeping the other floor parts dry.

Indeed, the size of shower pan matters.

In the market, you can find standard shower basin sizes measuring 32″ x 32″ to 42″ x 60″, with around 2″ to 6″ depths from the drain. Read on to determine what works for your bathroom.

Standard Shower Pan Dimensions


Standard shower pans have three standard sizes, and although they are common shower pan sizes, they come in various shapes and differ in their opening.

If there are small, medium, and large sizes, the shower floor pan sizes have the following:

Standard Shower Pan Type Sizes
Standard Shower Pans (Square) 32″ x 32″
Standard Shower Pans (Rectangular) 36″ x 48″
Standard Shower Pans (Neo-angle corner unit) 38″ x 60″

Regarding its depth, all three types of standard shower pans have a thickness of at least 2″ to 6″.

Please take note that a typical shower pan has a standard depth, and it is one factor that constitutes the efficiency of the standard shower pans.

Standard Shower Pans Uses


To better understand the standard shower pan’s measurements, we break them into three categories: square, rectangular, and neo-angle corner unit standard shower pans.

  • Standard Shower Pans (Square)

These are the smallest shower pans that you can get right now. Their vanity sizes are ideal for small spaces and bathrooms like those usually seen in tiny one-bedroom apartments or college dormitories.

  • Standard Shower Pans (Rectangular)

If you are looking for bigger yet standard shower pans that are disability-friendly, check the rectangular ones. Since the pans’ sizes have longer widths and standard vertical depths, these pans will fit perfectly into any disability-friendly bathroom.

Sizes Dimension
Small 32” x 48”
Medium 36” x 54” to 36” x 60”
Large 42” x 60” to 48” by 60”

If you are particular about where the water is heading, you might need extra time to figure out which way you want them to go since the standard shower pans (rectangular) have offset drains on their left or right side.

  • Standard Shower Pans (Neo-angle Corner)

Don’t confuse this type of pan with the standard shower pans (square). This shower pan, like the square ones, might be ideal for small showers, but they are entirely different.

The square standard shower pans fit just right enough to collect all the water and drain them. But, the Neo-angle corner standard shower pan’s designs and sizes are for people to move around the pan.

The extra inches of the pan’s size allow people to comfortably take a shower without worrying that the waters will splash around.

Also, the companies manufacturing the pans carefully design them to be suitable for a two-wall corner shower room.

Standard Shower Pans – Corner (Big) 60” (cross dimension)

Are Shower Pans Important?

Some homeowners think that shower pans are unnecessary and will cost them extra. They do not know that standard shower pans offer several significant benefits you must consider.

  • Safety

Safety is the primary benefit you will get when installing the shower pan. However, you must pick the product that best fits your shower space. This way, you won’t get any slick, wet or slippery floor, thus, less risk of slip-and-fall accidents while in the shower room.

This makes the standard shower pans ideal for households with children, elderly persons, or persons with disability.

  • Protects Your Bathroom Tiles

Nowadays, most bathrooms have tiles installed in them. Take note. These tiles are not waterproof, meaning they seep the water. Once the floor tiles start seeping water, it will lead to the accumulation of bacteria and damage your entire shower floor.

The tiles that cover your floor must be protected. Standard shower pans can address this issue, avoid overflowing water, and promote longer tile life.

How Do You Measure a Standard Shower Pan?


Numbers may be overwhelming sometimes but measuring a standard shower pan is not that complicated. It’s as easy as 1-2-3. All you need to have to compute the dimension are a tape measure, calculator, and pen and paper for note taking.

A quick reminder, whether it is your first time installing a shower pan or not, make sure that the pan’s drainage perfectly matches your existing shower drainage system.

  • Measure the shower pan’s width – Measure the shower pan’s outer border. To calculate the shower pan’s width, use your tape measure and measure the width from left to right.
  • Measure the shower pan’s depth – Start measuring the depth from the pan’s bottom to its opening or top edge.
  • Measure the drain’s location – Now that you have the value of the pan’s width and depth, the next thing you need to find is the value of the drain’s location. Measure the drain’s distance from the outside corners of the shower pans to the pan’s drain.

What Are Shower Pans Made From?

After more than 50 years since their initial release, shower pans have evolved from their classic designs to their modern look. Check these shower pan materials that give them a contemporary look today.

  • Acrylic


Acrylic or plexiglass is known for being impact-resistant, making it one of the best picks to consider.

But don’t be surprised if you see that the price tag for this shower pan is a little bit more costly than regular shower pans.

The materials used and the color options, which are aesthetically appealing, are worth it for that price tag.

  • Fiberglass


Choose a fiberglass shower pan if you are looking for functional but budget-friendly shower pans.

Aside from the cost that won’t break the bank, you can quickly find them in any home, construction, or supply shop.

  • Composite


The composite standard shower pans are considered the kings of shower pans. Regardless of its shower tray sizes, the composite materials’ synthetic polymers, stone, and price will let you experience what it feels like to have a premium product.

  • Custom Tile


Custom tile is another pricey product that can go head to head with composite. The good thing about having a custom tile as a shower tray is you can customize it completely to match your bathroom’s design and décor.

However, you need to check the sizes for tile before you customize it. It must match your entire bathroom floor’s tiles. Otherwise, it will look off and defeat the purpose of having a beautiful and aesthetic bathroom.
