Large walk in showers are a game-changer for bathroom renovation. They can greatly enhance the functionality and aesthetic appeal of a bathroom.

A well-designed walk in shower can make a significant impact on your daily routine. It's essential to consider the space constraints and limitations of your bathroom before designing a large walk in shower. In most cases, a walk in shower is a great option for small to medium-sized bathrooms.

To create a seamless experience, consider installing a walk in shower with a linear drain. This design allows for a more open and spa-like feel, and it's also easier to clean. A linear drain can also help to create the illusion of a larger space.

A large walk in shower typically requires a minimum of 3 feet by 5 feet of space. However, the ideal size will depend on your personal preferences and the specific design you choose.

Planning and Design

When planning a large walk-in shower, it's essential to consider the water pressure and flow rate to ensure a comfortable and enjoyable experience. A minimum flow rate of 2.5 gallons per minute is recommended to create a satisfying shower.

The shape and size of the shower area can greatly impact the overall design. A rectangular shape is often preferred for its ease of installation and maintenance.

To ensure proper drainage, a slight incline of the shower floor is necessary, typically around 1/4 inch per foot. This helps water flow towards the drain and prevents water from accumulating.

Choose an All-Over Tile

Choosing an all-over tile can create a seamless transition in your bathroom, especially in the walk-in shower area. This can be achieved by continuing the tile pattern from the rest of the bathroom.

Continuing the tile pattern into the walk-in shower can make the space feel larger and more cohesive. As seen in Example 2, the tile even covers the built-in bench.

Using a single type of tile throughout the bathroom can simplify the design process. This is because you can focus on a single style and color scheme.

In some cases, a single type of tile can be used to create a bold and striking look. For example, the smoky subway tile in Example 4 creates a mysterious and cool atmosphere.

To ensure a seamless transition, choose a tile that complements the existing tile in the bathroom. This can be achieved by selecting a tile with a similar color, texture, or pattern.

In Example 1, the author used slate tiles for the back wall and floor, creating a cohesive look.

Dry Fit and Frame Out

Dry fitting and framing out is a crucial step in planning and designing your shower remodel. You can use a 3×4 shower pan if your existing shower is 4 ft wide.

The position of the drain is also a consideration. If the existing drain is centered left to right but far from the front, you can create a space filler, like a bench seat and a full-length shelf.

A bench seat frame can be built to fill the space and allow the back of the pan to run along the front of the bench. Two false walls can be framed using 2x4s with space in between them to act as a shelf for shampoo and soap bottles.

You can also move the shower head to come out the side wall instead of the back wall. Chiseling out the old drain and extending the drain pipe may be necessary to accommodate the pan.

Cement board can be installed after the mud bed dries, and it can be laid in any pattern you like. This can add a decorative touch to your shower remodel.

Tools and Materials

To create a large walk-in shower, you'll need the right tools and materials. A tile saw is essential for cutting through tiles, and you'll also need a drill/driver for various tasks.

You'll need the following tools: a demolition hammer, prybar, tile saw, drill/driver, trowel(s), grout float, and grout sponge.

Some necessary materials include a shower pan, cement board, waterproofing, thinset/mortar, slate 4×12 tiles, slate 16 x 16 tiles, subway 4×12 tiles, grout, and tile sealer.

Black and White

Black and white marble can create a sleek and sophisticated look, as seen in a spa-like walk-in shower designed by Sarah Richardson. The combination of crisp black and white marble in a peaked design can resemble a hidden treasure.

Using black and white marble can add a touch of elegance to any space. This style is particularly well-suited for a picturesque A-frame chalet near a ski resort in Collingwood, Ontario.

Tools & Materials:

To tackle any project, you need the right tools and materials. For a tile installation, you'll need demolition tools like a hammer and pry bar to remove the old tile and adhesive.

A tile saw is also necessary for cutting tiles to the right size. You can't install new tile without it.

A drill/driver is another essential tool for this project. It's used for drilling holes for anchors and driving screws.

You'll also need trowels for spreading thinset and grout. Grout floats and sponges are used to spread and remove excess grout.

Here's a list of materials you'll need:

  • Shower pan

Preparation

Before installing a large walk-in shower, it's essential to plan carefully to ensure a smooth and stress-free installation process.

A crucial step in preparation is to assess the plumbing system, as mentioned in our previous section, which stated that the existing plumbing should be able to handle the increased water flow of a large walk-in shower.

Measure the space where the shower will be installed to determine the optimal size and layout, considering the minimum clearance of 36 inches between the shower and any surrounding walls or obstacles.

To ensure a safe and comfortable shower experience, consider installing a shower bench or seat, as discussed in our section on accessibility features.

Plan for adequate drainage, as a large walk-in shower will require a more powerful drain system to handle the increased water flow, which can be achieved with a linear drain or a shower pan with a built-in drain.

Demo the Existing

Demoing the existing shower is a crucial step in the remodeling process. It's a chore and can be quite messy, so be prepared for a challenge.

First, you'll need to remove the existing tile and cement board from the walls and floor. This involves using a prybar and a hammer to carefully take out all the tile and board.

To avoid getting into any plumbing or wiring behind the walls, tread lightly as you start to tear things out. It's essential to be cautious during this process.

Removing everything down to the studs and the concrete floor can be a time-consuming task, but it's necessary for a successful remodel.

In some cases, you may need to re-waterproof the area, which can be done by gluing a fabric onto the cement board with thinset.

Grout the Tiles

Grout the tiles after the tiles are set and dry, and apply sealer to slate tiles before grouting to prevent staining.

Slate is a pretty absorbent material, so sealing before grouting will help prevent the grout from sticking to the tiles. It's a good idea to work in small sections with the grout to clean it up with a damp sponge before it sets.

You can clean the grout with a damp sponge about three times, then come back the next day and clean it again with a dry towel to remove any remaining residue.

Grout should go in between all the tiles on the same plane and should fill any outside corners, but for inside corners, you skip the grout and use a sealant type caulk.

Frame the Alcove

I framed out the space between the existing wall and the shower pan with a bench seat and a full-length shelf, using 2x4s to create the frame. This allowed the back of the pan to run along the front of the bench.

A contrasting stone can be used to frame the alcove of a walk-in shower, adding a design moment to the space. Rose quartz, for example, can be used to create a feminine touch.

You can use a bench seat frame to fill in the space between the wall and the shower pan, making it easier to install the pan and creating a more functional area. This was my approach when I remodeled my shower.

To frame the alcove, you'll need to decide on a stone that fits your design vision. Consider the look and feel you want to create, and choose a stone that complements the rest of the bathroom.

Installation

The installation process for a large walk-in shower can be a bit overwhelming, but it's definitely doable with the right planning and tools. Install the shower pan and walls first, making sure the drain is prepped and the framing is complete.

For waterproofing, use a Schluter Kerdi membrane, which I found to be a game-changer in my DIY shower remodel. This membrane helps prevent water from seeping behind the tiles and causing damage.

To tile the shower walls, start by using a waterproofing membrane and let it dry before proceeding. I used slate 4x12 tiles for the back wall in a vertical pattern, which added a beautiful touch to the space.

Install Panelling and Walls

Installing panelling and walls is a crucial step in any installation project. The first thing to do is prepare the drain, which involves making sure it's prepped and ready for the pan.

The pan itself should be installed according to the manufacturer's instructions, and it's essential to ensure it's properly leveled up. I've found that using a level tool helps to get it just right.

After the pan is in place, it's time to install the Schluter Kerdi membrane for waterproofing. This is a critical step to prevent any water damage or leaks.

Getting the first row of panelling nice and level is key, as it sets the foundation for the rest of the installation. From there, you can build on top of it, row by row, to complete the walls.

New Door Style

If you're looking to give your bathroom a modern makeover, consider swapping out your traditional shower curtain for a glass closure on sliders. This small but impactful change can make a big difference in the overall look and feel of your bathroom.

A glass door can help make a small bathroom look bigger, as seen in one example where the glass helps the space appear larger.

In tight spaces, a glass closure on sliders is a great option because it doesn't require a lot of clearance to open and close.

This option also allows you to show off your bathroom's unique tile or design features, like the funky patterned tile in the example mentioned earlier.

Sleek and Accessible Ideas

Stall and Accessibility is not just about making stalls accessible, but also about making them sleek and user-friendly.

The key to creating a sleek and accessible stall is to consider the user experience from the very beginning of the design process.

The ideal stall height for users with mobility impairments is between 34 and 38 inches, as specified in the Americans with Disabilities Act (ADA) standards.

A well-designed stall can make a big difference in the lives of users with disabilities.

The use of grab bars and emergency alarms can also greatly enhance the accessibility of a stall.

In some cases, a stall may need to be designed to accommodate users with specific needs, such as a stall with a raised seat for users with mobility impairments.

Benefits and Ideas

A large walk-in shower can be a game-changer for your bathroom, and for good reason. It's easy to clean, thanks to flat surfaces and fewer corners where dirt and grime can build up.

One of the biggest advantages of a walk-in shower is its versatility. It can fit into any bathroom size, making it perfect for small or unusual spaces.

Accessibility is another major benefit of a walk-in shower. Unlike bathtubs or shower enclosures, they're much easier to enter and exit, making them ideal for people with mobility challenges.

A walk-in shower also has a minimalist, contemporary design that can enhance your bathroom's aesthetic. With fewer moving parts and a frameless look, it's a sleek and modern addition to any bathroom.

If you're working with a small bathroom, a walk-in shower can actually make it seem larger. By eliminating the need for a shower door or curtain, it creates the illusion of more space and makes your bathroom feel bigger than it actually is.
