What You Will Need

If you want to build a walk in shower without a door, there are a few things you will need. First, you will need to choose a location for your shower. The best place for a walk in shower is usually in a corner of the bathroom so that two walls can be used for support. Next, you will need to measure the space where you will be putting your shower. Once you have the measurements, you will need to purchase the materials needed to build the frame of the shower. These materials include 2x4s, plywood, and tile backer board. Finally, you will need to purchase the tile and grout for the shower.

Step One: Demolition

If you’re planning on installing a walk in shower, the first step is demolition. This involves removing any existing shower doors or curtain rods, as well as any tile or other materials that may be covering the opening of your shower.

Once the area is clear, you’ll need to measure the rough opening of your shower and mark it out on the wall. Be sure to leave enough space for any trim or molding that you’ll be adding later.

Next, use a hammer or chisel to remove any old caulking or sealant around the perimeter of the shower opening. Once that’s done, you’re ready to begin construction on your new walk in shower!

Step Two: The Base

After you have your framing and drain rough-in complete, it’s time to start thinking about the base of your shower. The base, or floor of your shower, needs to be sloped so that water will drain properly. A general rule of thumb is to slope the floor 1/4″ for every foot that it extends away from the drain. So, if your shower is six feet long, you would need to slope the floor 1 1/2″ from the drain to the far end of the shower.

There are a few different ways that you can create this slope. One option is to use a pre-sloped base pan. These pans come in all different sizes and shapes and can be made out of a variety of materials including fiberglass, acrylic, or tile.

Another option is to create your own sloped base using mortar and tile. This option gives you a lot more flexibility when it comes to customizing the look of your shower as well as choosing what type of tile you want to use. However, it is important to note that this option is more labor intensive and will take longer to complete than using a pre-sloped base pan.

Once you have decided on which method you are going to use to create your sloped base, it’s time to move on to step three: installing the walls.

Step Three: The Walls

The first step to building a walk in shower without a door is to remove any existing doors and frames. Next, you’ll need to measure the space and mark the studs on the wall. For this project, you’ll need two sheets of plywood, one for each wall.

Cut the plywood to size and then nail it into place. Make sure the seams are sealed with caulk. Next, apply waterproofing membrane to the walls using a brush or roller. Start at the bottom and work your way up.

Now it’s time to install the backer board. Cut it to size and then attach it to the studs with screws. Be sure to use moisture resistant screws and washers. Apply thinset mortar to the back of the backer board and then press it into place. Use a level to make sure it’s installed correctly.

Now you’re ready to tile! Apply thinset mortar to the backer board and then place your tiles into position. Use a level or straight edge to make sure they’re level as you go along. Once all of your tiles are in place, allow the thinset mortar to dry for 24 hours before grouting.

Step Four: The Showerhead

If you’re planning on having a walk in shower without a door, then you’ll need to pay special attention to the showerhead. This is because the showerhead will be one of the only things keeping water from spraying all over your bathroom.

There are a few things to keep in mind when choosing a showerhead for your walk in shower. First, you’ll want to make sure that the showerhead is durable and can withstand repeated use. Second, you’ll want to choose a showerhead that has a wide range of settings so that you can customize your shower experience. Third, you’ll want to make sure that the showerhead is easy to clean so that you can keep your bathroom looking its best.

Once you’ve chosen the perfect showerhead, it’s time to install it. The first step is to attach the mounting bracket to the wall. Next, you’ll need to connect the water supply lines to the back of the showerhead. Finally, you’ll screw the showerhead into place and turn on the water supply.

Step Five: Waterproofing

One of the most important steps in building a walk in shower without a door is to make sure that it is properly waterproofed. There are a number of different ways that you can do this, but one of the most effective is to use a waterproofing membrane.

There are a few different types of waterproofing membranes that you can choose from, but one of the most popular is called an asphalt-modified urethane (AMU) membrane. This type of membrane is designed to be applied directly to the substrate and then covered with a layer of tile or stone. It is important to note that AMU membranes are not always compatible with all types of tile and stone, so be sure to check with your manufacturer before using one.

Another popular type of waterproofing membrane is called a sheet-applied system. This type of system consists of two layers: an adhesive layer that is applied directly to the substrate, and a protective layer that goes over top of the adhesive. Sheet-applied systems are typically more expensive than AMU membranes, but they offer better protection against water intrusion.
