This design is not just about aesthetics or safety; it embodies the principles of universal design, which aims to make spaces usable by all people, to the greatest extent possible, without the need for adaptation or specialized design.

Whether you're planning a bathroom remodel for aesthetic reasons or to improve accessibility, a zero-threshold shower is a smart choice. It offers a combination of modern style and practical functionality, ensuring your bathroom is both beautiful and safe for years to come.

Benefits of Zero-threshold Shower Installation

Zero-threshold shower installation comes with several compelling benefits that can transform your bathroom into a more beautiful, safer, and leak-resistant space.

Improved Appearance

A zero-threshold shower creates a clean, modern look. By eliminating the curb, the bathroom floor and shower area become one seamless surface. This design choice makes the bathroom appear larger and more open.

You can customize the look with various tiles and finishes, giving you the freedom to tailor the space to your taste. Whether you prefer a sleek modern aesthetic or a more traditional style, a curbless shower can accommodate your vision.

Improved Safety

Safety is a major benefit of installing a curbless shower. Traditional shower curbs can be a tripping hazard, especially for seniors or those with mobility issues. A zero-threshold design removes this obstacle, providing safer access for everyone, including wheelchair users and those with walkers.



The risk of falls is significantly reduced, giving you peace of mind that your bathroom is safe for all family members.

Leak Prevention

Curbless showers also help in preventing leaks. Without a curb, there's one less area prone to water buildup and potential leaks. The seamless design allows for better water drainage, especially when combined with a properly sloped shower floor.

Using products like the TrueDEK Classic Base, which offers pre-sloped options, ensures efficient water flow towards the drain, minimizing the risk of water escaping the shower area.

Incorporating these elements in your bathroom remodel not only improves the aesthetic and safety of the space but also provides practical benefits that contribute to a long-lasting and functional bathroom design.

Step-by-Step Guide to Zero-threshold Shower Installation

Step 1: Determine the Location of the Base

To start your zero-threshold shower installation, you'll need to decide where to place the base. The TrueDEK Classic Base is a popular choice because it's pre-sloped and comes in various sizes. This flexibility allows you to adjust the base to fit your shower area perfectly.

Make sure the drain hole is clear of any floor joists. The TrueDEK base's drain offset design lets you rotate the base to avoid these obstacles. Once you've found the right spot, use a pencil to outline the base on your subfloor.

Step 2: Cut the Subfloor

With your base outline in place, it's time to cut the subfloor. Use a circular saw to follow the pencil lines you marked earlier. A multitool can help you finish cuts in the corners where the circular saw might not reach. Be prepared to use a pry bar to remove any stubborn pieces of subfloor.

Step 3: Reinforce the Floor

After cutting the subfloor, reinforce the area around the hole with 2x4 blocking. Secure the 2x4s using construction adhesive and 2 1/2″ screws. This provides extra support for the shower base and the drain area.

Step 4: Fasten Pan to the Floor

Now, it's time to install the shower pan. Apply construction adhesive to the areas of the floor that will contact the bottom of the TrueDEK base. Position the base in the cutout area and use an impact driver to drive screws through the pre-drilled holes into the floor joists and blocking.

Step 5: Install Backer Board on Floor

Next, cover the entire bathroom floor and the area around the shower base with 1/4″ cement board. For the shower walls, use 1/2″ cement board. Secure the boards and seal all joints and screw holes with latex caulk. Avoid silicone, as waterproofing materials won't adhere to it.

Step 6: Apply Waterproofing to the Curbless Shower

Waterproofing is crucial for a zero-threshold shower. Use waterproofing tape and Tank-10 waterproofing liquid to seal corners and joints. Brush Tank-10 onto each corner, place the waterproofing tape, and apply more Tank-10 on top. Repeat this process for all joints between cement board pieces and the base. Apply at least three coats for maximum protection.

Step 7: Install the Drain

The TrueDEK drain installation is straightforward, but follow the included instructions carefully. Once the drain is installed, apply Tank-10 around it and finish applying it to the rest of the shower base.

Step 8: Lay the Tile

Finally, it's time to lay the floor tile. While this process can be complex, one key tip is to back butter the tiles around the perimeter to create a slope away from the walls. This ensures proper drainage and maintains the seamless look of your zero-threshold shower.

With these steps, you're well on your way to enjoying a sleek, modern, and safe curbless shower.

Frequently Asked Questions about Zero-threshold Shower Installation

Can I make my shower curbless?

Absolutely! Transitioning to a zero-threshold shower can improve the look and functionality of your bathroom. To achieve this, you'll need to consider your floor's structure. Specifically, ensure that the floor joists can accommodate a recessed area for the shower base. This recessed area is crucial for creating the necessary slope for water drainage without a curb. The TrueDEK Classic Base is a great option because its design allows flexibility around floor joists, preventing potential installation issues.

How much does it cost to install a curbless shower?

The cost of installing a curbless shower can vary based on several factors, including the size of your shower, the type of tiles you choose, and any additional features you want. On average, homeowners can expect to spend more on a curbless shower than a traditional one due to the need for specialized materials and potential structural modifications. Tile choices significantly impact the total cost; high-end tiles will increase expenses, while more budget-friendly options can help keep costs down. It's always a good idea to consult with professionals, like those at Accountable Home Remodeling, to get a personalized estimate.

How deep does a curbless shower need to be?

The depth of a zero-threshold shower is crucial for effective water drainage and user comfort. While there isn't a one-size-fits-all answer, the shower should be deep enough to allow a proper slope towards the drain, typically a minimum of 1/4 inch per foot. This ensures water flows smoothly to the drain without pooling. Additionally, the size of the shower should accommodate any assistive devices, like wheelchairs, if needed. This means considering both the width and depth to ensure accessibility and comfort for all users.
