Installing a shower stall pan can be a bit of a challenge, but with the right design and installation, it can be a breeze.
A shower stall pan is typically made of acrylic, fiberglass, or solid surface materials, which are durable and easy to clean.
To ensure a watertight seal, it's essential to choose a pan with a built-in drain and a slight slope to allow water to flow freely towards the drain.
A well-designed shower stall pan can also help to prevent water damage and make cleaning a lot easier.
The size of the pan will depend on the space available in your bathroom and the style of your shower, with standard sizes ranging from 30 to 60 inches in length.
A larger pan will provide more space for your shower, but may require additional support and drainage solutions.
Types of Shower Stall Pans
There are several types of shower stall pans, each with its own unique characteristics.
Acrylic pans are a popular choice due to their affordability and ease of installation.
They are also lightweight and easy to clean, making them a great option for small bathrooms.
Concrete pans are known for their durability and can be customized with different colors and designs.
They are also resistant to mold and mildew, making them a great choice for bathrooms with high humidity.
Fiberglass pans are another option, offering a sleek and modern look.
They are also resistant to water damage and can withstand heavy use.
How to Choose a Seat
Choosing the right seat for your shower stall pan is crucial for a comfortable and safe bathing experience. The type of seat you choose should match the type of shower stall pan you have.
If you have a fiberglass shower stall pan, a plastic seat is a good option. It's lightweight, easy to clean, and resistant to mildew.
A wooden seat is a better choice for a tile shower stall pan. It's durable and can withstand the moisture, but it may require more maintenance.
Consider the height of the seat as well. A seat with a height of 17-19 inches is ideal for most adults.

Base Difference
A shower base and a shower pan may seem like interchangeable terms, but they have some key differences. A shower base is a pre-made, fiberglass unit that's easy to install, but it can cost between $500 to $1,000.
Shower bases can be installed in a day, making them a quick fix for a bathroom renovation. On the other hand, a shower pan is a custom-built, tile-finished unit that takes more skill to install and can take several days to complete.
Improperly constructed shower pans can leak water, which is a major concern for homeowners. You can mitigate this risk with a one-piece shower base.
The cost difference between the two is significant, with shower pans ranging from $200 to $250, while tile is extra.

Premade shower pans are generally quicker and cost less to install than site built pans, which are typically used for tile showers. This makes them a more attractive option for DIYers or those on a budget.
If you're not comfortable with plumbing skills, such as installing the shower drain, it's best to call a professional.
Custom Tile
Custom tile shower pans offer notable versatility, especially when it comes to safety. Tiles with textured surfaces can enhance safety by preventing slips on wet surfaces.
For a discerning home decorator with specific tastes, custom tile can be an excellent option. It requires routine maintenance, however, as regular cleaning of grout lines is needed to prevent serious mold and mildew growth.
You can choose between two main options for tile installation: the Tileable Shower Base System and the Tile Over Concrete method. The former involves purchasing a pre-made, tile-ready floor pan, while the latter allows you to lay tiles directly over a concrete base.
The Tileable Shower Base System is easy to install and simplifies the process of creating a shower space. This option typically includes chrome drains.
For the Tile Over Concrete method, it's essential to use highly waterproof materials for laying tiles, since neither tile nor grout is waterproof.
Here are some options for stylish shower pans:
- Low profile stone shower pans with matching square strainer covers
- Tile shower pans, which can be used to create a "work of art" with the right tile shower pan design
How to Get the Best Shape
Standard shaped shower pans are more cost-effective and can be made in molds, but they come in various shapes and sizes to fit different bathroom designs.
You'll find standard shaped pans in corner styles, including square, round, NEO angle, and rectangular. Square, round, or NEO angle pans are great for small bathrooms as they're space-efficient.
For an alcove style shower, rectangular standard shower pans with wall surrounds for the other three sides are popular. They come in common sizes like 48" x 32", 48" x 36", 60" x 30", 60" x 32", and 60" x 36".
If you want a 'walk-in shower' with a framed wall in the front, you'll need a custom offset shower pan made of solid surface or cultured granite.
Custom shaped pans with unique angles and round shapes are possible, but be prepared to pay more for them. You'll need to invest in solid surface or tile pans, as standard acrylic and fiberglass pans can't be customized.
To maximize your flexibility if you don't know the exact size you need, consider buying a shower pan that's 'trimmable'. Trimmable pans have flanges that aren't factory installed and can be put on after the pan is cut to size.
How to Install Quickly
A quick installation is just what you need to get your shower remodel done in no time.
Premade shower pans are quicker to install than site built pans, which can save you time and money.
If you're looking to minimize your installation time, consider a premade shower pan.

These pans are available in standard and custom sizes, making them a convenient option for many projects.
A premade shower pan is a great choice if you want to reduce your contractor's quote or your own DIY workload.
Site built pans, on the other hand, are often used for tile showers and can be more time-consuming to install.
When to Hire a Professional?
If you're planning a DIY renovation, it's essential to know when to call in the experts. Plumbing skills are required to install a shower drain, so if you're not comfortable with this aspect of the project, call a pro.
Shower pans also need to be installed correctly to avoid leaks and water damage. Hire a pro if this project is above your skill level.
Mortar Layer
The mortar layer is a crucial part of a shower pan, providing a durable and waterproof surface for the floor. It's composed of a sloped fill layer, which is essentially a mortar subfloor sloped toward the drain.
A sloped fill layer is necessary to direct water toward the special two-piece clamping-type drain. The sloped fill slants from the drain toward the perimeter of the shower.
To install the first layer of mortar, you'll need to remove the top half of the shower drain and plug the drain pipe with a rag. This prevents debris from falling into the pipe.
Here's a step-by-step guide to installing the first layer of mortar:
- Remove the top half of the shower drain and plug the drain pipe with a rag.
- Measure and mark a line 1-in. from the subfloor along the inside of the 1/2-in. plywood for curved curbs.
- Pile mortar against the curved plywood and compact it down to the line with a wood float.
- Pack the remaining shower area with mortar using a wood float, then use the 1×4 screed board to screed the mortar along the 1-in. screed guides.
- Work the surface smooth with a wood float and smooth with a steel finish trowel.
- Let the mortar harden overnight.
A layer of expanded galvanized metal lath on top of the pan reinforces the mortar, providing additional support and stability.
Adjust the Drain
Adjusting the drain is a crucial step in the installation process. You'll need to use needle-nose pliers to raise the shower drain by unscrewing it until it's the same height as the floor tile.
This adjustment is essential before the mortar sets, as it ensures the drain is properly aligned with the surrounding tile. Make sure to take your time and get it right, as this will affect the overall appearance of your shower.
By raising the drain to the correct height, you'll create a seamless look that's visually appealing. It's a small detail that can make a big difference in the final result.
I Hate Bases with Them!

I HATE, HATE, HATE shower bases with seats built into them! It's a design choice that can be a major headache, especially in small bathrooms.
Most people don't have showers as large as they'd like, and a shower pan with a seat built into it can suck up a lot of room. Plus, it's significantly more expensive than a standard shower pan.
You can avoid this problem by buying a shower pan without a seat molded into the base and using a fold-down seat instead. There's a nice selection of stylish shower seats available.
Here are some options for stylish shower seats:
- Use a fold-down seat that can be placed exactly where you want it.
- Choose a seat with a modern design that fits your bathroom style.
- Consider a seat with a built-in backrest for added comfort.
If you do decide to use a shower pan with a seat built into it, be aware that it will take up more space and cost more money. But if you have a large custom shower, it might be a good option for you.
A shower base with a built-in seat can be a real space-saver, but it's not always the best choice.

Materials and Options
Fiberglass shower pans are a budget-friendly option, but they can be fragile and prone to cracking or breaking.
A fiberglass shower pan can be challenging to find in a custom size, as this material is not as popular as others.
Fiberglass shower pans are also porous, which means they can absorb moisture and require regular maintenance to reduce the risk of mold and bacteria growth.
Acrylic shower bases are a step up from fiberglass and offer more strength and durability, with some units featuring reinforcements underneath the top surface to minimize squeaking.
Solid surface shower pans are even more durable and thick, but come at a higher price point than fiberglass and acrylic.
Tile shower pans offer the most design flexibility, but labor costs to install them drive prices up.
These shower pan materials vary in terms of durability, maintenance requirements, and price point, so it's essential to consider your long-term needs and budget before making a decision.
Popular Materials
Cast iron shower pans are highly regarded for their impressive durability and long-lasting performance, resisting scratches, chips, and cracks.
Molded stone, also known as resin stone, is a blend of natural stone resins and synthetic plastic compounds, offering a solid structure and durability.
Acrylic shower bases are crafted from acrylic plastic and reinforced with fiberglass, making them considerably firm and easy to clean.
Fiberglass shower pans are lightweight and inexpensive to install, but they can be fragile and prone to cracking or breaking.
Tile shower pans offer a ton of design flexibility, but the labor costs to install a tile base drive prices up.
Cast iron pans require professional installation, which can be very costly, but they hold onto heat well, providing a cozy surface.
The most expensive bases are tile shower pans, while the cheapest shower pan options are fiberglass and acrylic.

The Layers
A shower pan consists of a sloped fill layer, a waterproof membrane, metal lath, and a sloped mortar bed.
The sloped fill layer is simply a mortar subfloor that's sloped toward a special two-piece clamping-type drain.
The second layer is a durable chlorinated polyethylene (CPE) membrane, also known as a vinyl liner, which turns up at the edges to create a waterproof membrane in the shape of a shallow pan.
A layer of expanded galvanized metal lath on top of the pan reinforces the mortar, providing added strength to the structure.
The curb, usually four inches from the floor, contains water in areas that aren't bordered by walls, and is integrated into the design of the shower pan.
Planning and Preparation
Before you start shopping for a shower stall pan, it's essential to plan and prepare your space. This means considering the tile layout, as it's easier to determine this if you select your wall tile ahead of time.
Don't forget to account for edges and corners, and shift the starting point if needed. It's also crucial to plan for the thickness of the tile and the cement board.
If you're installing a shower door, pick it out in advance to ensure the shower opening accommodates it. Consider other bathroom doors and fixtures when determining the size of the shower door and the direction it should swing.
Plan Your Layout
Planning your layout is crucial to a successful shower installation.
First, determine the size and position of your shower based on the tile layout. Select your wall tile ahead of time to make this process easier.
Consider the edges and corners of the tile and shift the starting point if needed.
Next, think about the shower doors. Pick out your door in advance to ensure the shower opening accommodates it. Don't forget to account for the thickness of the tile and the cement board.
The direction the door should swing should also be considered, taking into account other bathroom doors and fixtures.
Finally, plan for the plumbing configuration, especially if you're installing your shower in a remote location.
Build vs. Buy
Building a shower pan versus buying a pre-formed unit is a decision that requires some thought. You can buy a fiberglass or acrylic shower base from a home center, which is a pre-formed single piece unit that's set into a mud base on the floor and screwed into the wall to install.

Traditionally, pros had to build a custom shower pan by mixing and applying mortar, troweling it flat, and laying ceramic shower floor tile. This method has been used for decades.
Many contractors today prefer pre-formed pans because they're faster to install. They're a modern alternative to building a shower pan.
Today's shower pans can be a pre-formed, pre-sloped foam pan that is then waterproofed and tiled over.
What Slope Should a Surface Have?
A surface with the right slope can make all the difference in water flow and overall functionality. A standard slope for a shower pan is 1/4-in. per foot from the drain to the perimeter. This ensures water drains properly and doesn't accumulate.
How to
Planning and preparation are key to a successful event. To start, define your goals and objectives, including the purpose, target audience, and desired outcome. Identify the resources you'll need, such as budget, personnel, and equipment.
