Installing a DIY shower stall can be a fun and rewarding DIY project, but it requires some planning and preparation. According to the article, a standard shower stall is typically 30 inches wide and 60 inches long.
Before you start, you'll need to measure your bathroom space to ensure the shower stall fits comfortably. Measure the area where you want to install the shower stall, taking note of any plumbing, electrical, or ventilation components.
A level is essential for ensuring the shower stall is properly aligned and installed. You can purchase a level at most hardware stores or home improvement centers.

Prepare the Area
Preparing the area for your DIY shower stall is a crucial step that will save you time and headaches in the long run. It's essential to check that your shower alcove is framed properly and in good condition. The walls should be square in both corners and plumb all the way around.
Use a level to confirm this, it's a simple but often overlooked step. Make sure the entire subfloor is level, it's not necessary to have it perfect at this stage, but it should be close.
Measure the width and depth of your alcove, double-checking the dimensions against the shower you're putting in. You can use a tape measure or a ruler to get accurate readings.
Rough-in the drain line so the opening of the drainpipe will line up with the drain on your shower base. The top of the drain line should be even with the subfloor. Don't forget to rough-in the plumbing for the showerhead and control valve on one of the side walls.
Here's a quick checklist to help you stay on track:
- Check the shower alcove is framed properly and in good condition.
- Measure the width and depth of your alcove.
- Rough-in the drain line.

Removing the Old Shower
Removing the old shower is a necessary step in the DIY shower stall process. It's a messy job, so be prepared to get your hands dirty.
First, put on some gloves to protect your hands from the rough tile and cement board. Grab a prybar and a hammer to remove the old tile and cement board from the walls and floor of the shower.
Be careful not to get into any plumbing or wiring behind the walls, so tread lightly as you start to tear things out. Removing everything down to the studs and the concrete floor is a must.
You may need to move the shower head to a different location, like from the back wall to the side wall. This will give you a better starting point for your new shower stall.
Removing the old shower can be a daunting task, but it's essential to get it right.

Building the New Shower
Building the new shower requires some planning and preparation. Clear and prepare the intended shower site by removing bathroom tiles or other floor coverings and installing the shower directly on the base of the floor itself.
To ensure a level surface, place 3 or 4 mounds of gypsum plaster or bricklayer’s mortar on any low spots in the subfloor. This will make leveling easier and provide additional reinforcement.
The next step is to install the shower pan or prefabricated unit. Slide the pan or unit in place and attach it using screws. You may need to build a frame to support the stall, depending on the type of shower kit you have.
For most installations, you'll need to install the plumbing after the shower pan is in place. This may involve attaching the strainer to the drain with screws, and securing the shower base to the studs using roofing nails.
To waterproof your shower, you can use a Schluter Kerdi membrane. This involves gluing the fabric onto the cement board with thinset, and laying it in a pattern of your choice.
Installing Panels
Installing panels is a crucial step in building your DIY shower stall. Ensure the back and side panels are properly seated on the shower base.
When adding insulation, consider your climate and the noise levels you're trying to achieve. This is especially important if you live in a cold climate, as insulation will help deaden any noise made by the plumbing and insulate the outside walls from the cold.
To attach the panels, use 1 1/2-inch self-tapping washer head screws or galvanized roofing nails, pre-drilling pilot holes through the flange if necessary. This will help ensure you don’t split the flange.
Here are the key steps to keep in mind:
By following these steps, you'll be able to securely attach your panels and create a sturdy shower stall.
Installing the
Installing the plumbing panels requires some careful planning and execution. Make sure the plumbing wall fits into its slots and the drilled holes line up with the plumbing fixtures.
To secure the enclosure, pre-drill the flange along the top at each stud, and then down the side 8 inches on center. Use 1 1/2-inch self-tapping washer head screws or galvanized roofing nails to fasten it at each stud.
Installing the shower requires some preparation, including clearing and preparing the intended shower site. This may involve removing bathroom tiles or floor coverings to install the shower directly on the base of the floor.
Here's a list of steps to follow for installing a shower:
- Clear and prepare the intended shower site.
- Build a frame to support the stall (if applicable).
- Install the shower pan/prefabricated unit.
- Install the plumbing (if you have not already done so).
- Install the sides of the shower stall (if applicable).
- Finish the project by covering exposed framing with water-resistant drywall and sealing seams with silicone-based caulk.
Insert and Attach Back Panel
Insert and Attach the Back Panel is a crucial step in the process. This is especially important if you live in a cold climate.
Before putting in the back and side panels, consider adding insulation and a vapor barrier. This will help deaden any noise made by the plumbing and insulate the outside walls from the cold.

Place the back shower wall against the studs and lower it down onto the base. Make sure it is seated correctly and firmly on the shower pan.
If your unit has pre-drilled holes, simply screw it in to the stud at the indicated points. If it does not, use a 3/8-inch bit to drill pilot holes through the flange. This will help ensure you don’t split the flange.
Here's a quick checklist to keep in mind:
- Add insulation and a vapor barrier if you live in a cold climate.
- Seat the back shower wall correctly and firmly on the shower pan.
- Use pre-drilled holes or drill pilot holes through the flange if necessary.
Install Side Panels
Installing the side panels is a crucial step in building your shower enclosure. The side panel should be seated properly on the shower base.
You'll need to attach the side panel to the stud on the vertical side flange, 8 inches on center. This is a standard spacing that ensures a secure hold.
Fasten the enclosure at each stud with 1 1/2-inch self-tapping washer head screws or galvanized roofing nails. These types of screws provide a strong and durable hold.
Some units have locking tabs that fit into slots in the base. If your unit has these tabs, simply place the side panel up against the back panel and slide it down into place. The locking tabs should fit into the slots, both in the base and the back panel.
Here are the steps to follow for installing the side panels:
- Insert the side panel and make sure it is seated properly on the shower base.
- Attach the side panel to the stud on the vertical side flange, 8 inches on center.
- Fasten the enclosure at each stud with 1 1/2-inch self-tapping washer head screws or galvanized roofing nails.
Finishing the Shower
To get a nice finished look, use water-resistant green board to cover any exposed walls. Make sure it covers the flange on all sides.
You'll want to leave a 1/8-inch gap for caulk, which will be your guide for priming and painting the walls. Prime and paint the walls, and caulk in the gap where the drywall meets the flange.
The shower's hardware, like the handle, shower arm, and showerhead, should be installed according to the manufacturer's instructions. Don't forget to cover any exposed holes with trim pieces.
Finally, add the finishing touches with a shower curtain or install shower doors to complete the enclosure.
Here's a quick checklist to keep you on track:
- Use water-resistant green board to cover exposed walls.
- Leave a 1/8-inch gap for caulk.
- Install hardware according to manufacturer's instructions.
- Add a shower curtain or install shower doors.
Finish the Room
To finish the room, you'll want to start by using water-resistant green board to cover any exposed walls. This will give your shower stall a nice, finished look.
Make sure the green board covers the flange on all sides, so you don't have any gaps or uneven edges. A 1/8-inch gap is left for caulk, which you'll apply after priming and painting the walls.
Now, let's talk about installing the shower fixtures. The manufacturer's instructions should be followed carefully for the handle, shower arm, and showerhead. Don't forget to cover any exposed holes with trim pieces.
Finally, add a shower curtain or install shower doors to complete the enclosure. This will not only make your shower stall look finished, but it'll also help keep water from splashing out.
Remodeling Considerations
When planning a DIY shower stall, consider the space constraints of your bathroom. The average bathroom is around 5 feet by 8 feet, so you'll want to choose a shower stall that fits comfortably within that space.
To save time and money, you can reuse the existing plumbing and electrical fixtures in your bathroom. Just make sure to measure the distance between the water supply lines and the drain to ensure your new shower stall fits properly.
A prefabricated shower stall can be a cost-effective option, with prices ranging from $300 to $1,200, depending on the size and features.

Reasons for Remodeling
Remodeling a bathroom can be a daunting task, but it's often necessary to fix underlying problems. In our case, the main reason for remodeling the bathroom was the shower, which had a significant issue with water pooling at the front corner instead of running towards the drain.
A 4×9 tile floor shower may look fine at first glance, but it can be a lot to keep clean. We've learned from experience that a large walk-in tile shower is not as practical as it seems.
The existing shower had cracked and missing tiles, dark grey grout smears on the ceiling, and missing caulk at the top. This created a messy and potentially hazardous environment.
Galvanized pipe is not suitable for a shower head, and in our case, it had rusted and stained some of the tiles. This was a major issue that needed to be addressed.
A single unit shower or acrylic shower base can be a better option than a tile shower floor, especially for those who want a low-maintenance bathroom.
What's Changing
I didn't want to take a chance on replacing the shower floor only to end up with the same issue as before with incorrect sloping and pooling water.
Installing an acrylic shower pan can be a great solution to avoid these problems. Everyone's situation will vary, so it's essential to do your own research for your own project.
Replacing the shower floor with an acrylic shower pan allows for a more efficient and effective remodeling process. This can save time and money in the long run.
