How To Build A Walk In Shower With Bench: A Comprehensive Guide in 2023

A walk in shower with bench can add both style and function to your bathroom. Not only does it provide a place to sit and relax while you shower, but it can also be a great design element in your bathroom. Follow these simple steps to build your own walk in shower with bench.

What You Will Need

Assuming you have a typical alcove style shower, building a walk in shower with a bench requires only a few tools and materials. The first thing you will need to do is remove the existing shower door and any trim. Next, using a stud finder, locate the studs in the wall so that you know where to install the new framing.

Once the studs are located, begin by installing new 2×4 framing along the back wall of the shower at least 6 inches above the existing framing. This new framing will provide support for the backer board and tile. Repeat this process along the side walls of the shower, making sure to leave room for the door opening.

Now it’s time to install backer board on all of the exposed walls. You will want to use at least 1/2 inch thick backer board so that it is durable and waterproof. Once the backer board is in place, you can begin tiling your shower. Be sure to use waterproof grout so that your shower stays leak free.

Last but not least, you will need to install a new door or curtain for your walk in shower. Make sure that whatever you choose is water resistant so that it lasts for years to come!

Step One: Planning The Layout

Before you begin building a walk in shower with bench, it is important to first plan the layout. This will ensure that the finished product is both functional and aesthetically pleasing.

When planning the layout of your walk in shower with bench, there are a few things to keep in mind. First, you need to decide where the shower will be located. It is important to choose a spot that is easily accessible and has plenty of space.

Once you have chosen the location for your shower, you need to determine the size of the area. This can be done by measuring the length and width of the space. Once you have these measurements, you can start planning the layout of your shower.

When it comes to deciding on the specific layout of your walk in shower with bench, there are a few options. One option is to have a single large bench that spans the entire length of the shower. Another option is to have two smaller benches that are placed opposite each other.

Once you have decided on the general layout of your shower, it is time to start planning the specifics. This includes choosing the type of material that will be used for your benches and walls. There are a variety of different materials that can be used, so it is important to choose one that best suits your needs and taste.

Step Two: Installing The Drainage System

Assuming you have a solid shower pan in place, the next step is to install the drainage system. The most common type of drainage system for a walk-in shower is a linear drain. Linear drains are installed along one side of the shower and have a long, narrow grate that allows water to flow evenly into the drain.

If you are installing a linear drain, you will need to install a waterproof membrane on the entire shower area (including the bench) before you install the drain. The membrane will help keep water from seeping through cracks and onto the floor.

Once the membrane is in place, you can install the linear drain. Start by attaching the drain body to the floor using screws or adhesive. Then, connect the drain grate to the body. Make sure all connections are secure and free of leaks.

Now that your drainage system is installed, you can move on to Step Three: Installing The Shower Walls!

Step Three: Laying The Tile

Once the mortar has had time to set, it is time to lay the tile. Begin by laying the first row of tile along the bottom edge of the shower base. Make sure to use a level to ensure that your first row of tile is straight. Once the first row is in place, you can begin working on the rest of the shower walls.

When you get to the area where the bench will be located, you will need to cut some tiles to fit around it. A wet saw is the best tool for this job, but you can also use a jigsaw or a utility knife. Just be sure to wear protective eye gear and gloves when using any power tools.

After all of the tile is in place, you can grout it. Be sure to wipe away any excess grout from the surface of the tile so that it doesn’t get hard and difficult to remove later on.

Step Four: Building The Bench

After the frame of your shower is complete, it’s time to start building the bench. The first step is to cut the lumber to size. You will need two pieces for the seat and two pieces for the backrest. Next, attach the seat legs to the frame with brackets or screws. Then, add the backrest supports and screw them into place.

Now you can begin adding the decking boards to create the bench seat. Start at the front and work your way back, attaching each board with screws or nails. Make sure that the boards are level as you go. Once all of the seat boards are in place, you can add trim around the edges if desired.

Now it’s time to install the tile on the shower floor and walls. Begin at the bottom and work your way up, using mortar or adhesive to set each tile in place. Apply grout between each tile once they are all in place. Allow everything to dry completely before using your new walk in shower with bench!


Building a walk in shower with bench is a great project for anyone who wants to improve their home. Not only does it add value to your home, but it also provides you with a place to relax and unwind after a long day. With a little bit of planning and some elbow grease, you can build a beautiful walk in shower that will be the envy of your neighborhood. Thanks for reading and good luck!
