Let’s get started!

Planning and Design

Shower Niche Design: Designing a shower niche involves choosing between custom, preformed, and modified options based on your shower’s dimensions and your design preferences.

Custom Niches: Custom niches are designed to fit specific measurements and design needs. This option allows for flexibility in size, shape, and placement, accommodating unique bathroom layouts and aesthetic requirements. You can tailor the niche to match your shower’s exact dimensions, ensuring it integrates seamlessly with the overall design. Custom niches are ideal if you have specific needs, such as a non-standard tile layout or a unique space configuration. This approach often involves more planning and can be more costly, but it provides the most personalized solution.

Preformed Niches: Preformed niches are factory-made units that come in standard sizes and shapes, making them a convenient option for many bathrooms. They are designed for easy installation and typically include built-in waterproofing, reducing the need for additional measures. However, preformed niches may not always fit perfectly with your existing tile layout or shower dimensions, which can lead to visible seams or awkward placement. These niches are a quicker solution compared to custom designs but might require some adjustments to fit seamlessly into your bathroom.

Modified Niches: Modified niches involve adapting preformed units to better fit your specific needs. This might include trimming the edges of a preformed niche or combining several units to achieve the desired size and shape. Modifying a preformed niche allows you to benefit from the convenience of pre-fabrication while tailoring the niche to better match your shower design. This approach can be a practical compromise if you find a preformed niche close to what you need but requires some customization to fit perfectly.

Tile Layout: The tile layout around your niche plays a critical role in ensuring a cohesive and visually appealing shower design.

• Aligning Tiles: Proper alignment of tiles is essential for creating a seamless look. The tiles inside the niche should align with those on the shower walls to maintain consistency and avoid awkward gaps or uneven lines. Careful planning is needed to ensure that grout lines and tile patterns flow naturally from the wall into the niche. This alignment helps in creating a visually pleasing and professional finish, making the niche appear as an integral part of the shower rather than an afterthought.
• Tile Coordination: Coordinating the tile colors and patterns between the niche and the rest of the shower is key to achieving a harmonious design. Choose tiles for the niche that complement the wall tiles in terms of color, pattern, and size. This coordination enhances the overall aesthetic and prevents clashes that can detract from the design. For example, if you have a bold pattern on the shower walls, a simpler tile in the niche can help to balance the look and keep the design from becoming too overwhelming.

Framing Considerations: Framing is a crucial step in the installation of a shower niche, as it provides the necessary support and ensures stability.

• Blocking: Adding blocking, which involves installing extra wood supports within the wall cavity, is essential for providing a sturdy backing for the niche. This support prevents the niche from shifting or collapsing and ensures it can hold the weight of the tiles and any items stored in it. Proper blocking also helps in achieving a flush installation and maintains the structural integrity of the wall around the niche.
• Stud Cutting: When framing for a niche, you may need to cut into wall studs. It’s important to distinguish between exterior walls, load-bearing walls, and non-load-bearing walls. Cutting into exterior walls or load-bearing walls can compromise the structural integrity of your home and is generally avoided. Instead, focus on non-load-bearing walls where modifications are less likely to affect the building’s stability. If stud cutting is necessary, ensure that you reinforce the area adequately to maintain support.

Wall Types: Understanding the type of wall you are working with is crucial for choosing the right materials and methods.

• Exterior Walls: These walls face the outside environment and may be subject to temperature fluctuations and moisture. When installing a niche in an exterior wall, it is essential to ensure proper insulation and weatherproofing to prevent moisture ingress and energy loss. Additionally, extra care should be taken to seal any openings around the niche to protect against drafts and ensure the longevity of the installation.
• Load-Bearing Walls: Load-bearing walls support the weight of the structure above and should not be modified without professional consultation. Cutting into these walls can affect the structural integrity of your home and is generally avoided unless necessary structural reinforcements are made. When planning to install a niche, choose non-load-bearing walls whenever possible to avoid compromising the building’s stability.
• Non-Load-Bearing Walls: These walls do not support structural weight and are ideal for modifications such as installing a shower niche. Non-load-bearing walls offer more flexibility and are easier to cut and frame for niche installation. Ensure that the wall is adequately supported and reinforced as needed, but modifications are generally less complex compared to load-bearing walls.

Building Materials

Foam Boards: Foam boards are a popular material for constructing shower niches due to their waterproof properties and ease of handling.

• Waterproof Properties: Foam boards are designed to be water-resistant, which is crucial for areas exposed to high humidity and moisture like shower niches. They help prevent water damage and mold growth by providing a waterproof barrier. The inherent waterproof nature of foam boards reduces the need for additional waterproofing layers, simplifying the installation process.
• Ease of Cutting: Foam boards are easy to cut with a utility knife, allowing for precise and straightforward adjustments during installation. This ease of cutting helps in creating a custom fit for the niche and reduces the time and effort required for installation.

Construction Steps for Building a Better Shower Niche

Backer Board Installation:

1. Cutting the Backer Board: Start by measuring the dimensions of the niche carefully. Transfer these measurements to the backer board, ensuring you account for any adjustments required for precise fitting. Use a utility knife for straight cuts or a circular saw for larger, more intricate cuts. The backer board will serve as a foundational layer for tiling, providing a stable and moisture-resistant surface. Ensure that all cut edges are smooth to prevent any gaps or uneven surfaces once the tiles are installed. The backer board should fit snugly within the niche, with a small gap of about 1/8 inch around the edges to allow for expansion and movement.
2. Applying Thinset: Once the backer board pieces are cut to size, apply a layer of thinset adhesive to the wall where the backer board will be installed. Thinset, a type of mortar, acts as a bonding agent between the backer board and the wall surface. Using a notched trowel, spread the thinset evenly, creating ridges that will help the backer board adhere securely. The consistency of the thinset should be smooth, not too thick or runny. Proper application of thinset ensures a strong bond, preventing the backer board from shifting or loosening over time.
3. Securing with Screws: Position the backer board against the wall, pressing it firmly into the thinset. Use cement board screws to secure the backer board to the wall studs. Space the screws approximately 8 inches apart along the edges of the board and every 12 inches in the center areas. Ensure that the screws are driven in flush with the surface of the backer board to avoid creating bumps under the tile. Proper screw placement is essential for a stable and secure installation. Be careful not to overtighten the screws, as this can cause the board to crack or become damaged.
4. Ensuring Proper Alignment: After securing the backer board, use a torpedo level to check that it is perfectly level and aligned. Place the level across the surfaces of the backer board to ensure there are no high or low spots. Proper alignment is crucial for a professional-looking tile job. If any adjustments are needed, make them before proceeding with tile installation. An even surface ensures that the tiles will be laid flat, reducing the risk of uneven grout lines and gaps.

Slope:

1. Creating a Proper Slope: At the bottom of the niche, it’s important to create a slight slope to facilitate proper drainage. The recommended slope is approximately 1/8 inch per foot, ensuring that any water that enters the niche will flow towards the drain rather than pooling. To achieve this, use a straightedge or level to measure and mark the desired slope. You can build up the slope using a thin layer of mortar or by adjusting the backer board installation. Proper slope ensures that the niche remains dry and free from standing water, which can cause mold and mildew growth.
2. Checking the Slope: Once the slope is created, use a torpedo level to verify its accuracy. Place the level across the bottom of the niche to ensure that the slope is consistent from one end to the other. Adjust as needed before proceeding with the tile installation. A properly sloped surface is critical for effective water drainage and to prevent water damage within the niche. After verifying the slope, allow any mortar or adjustments to set before moving on to the next steps.

Sealing and Waterproofing:

1. Applying Sealant: For foam boards, apply a bead of sealant around the edges where the foam board meets the wall to ensure a watertight seal. Use a caulk gun to apply the sealant evenly, pressing it into any gaps or joints. For cement boards, cover all seams and corners with mesh tape, then apply a thin layer of thinset over the tape to seal the seams. Sealant prevents water from penetrating behind the backer board, which could lead to mold and water damage.
2. Using Mesh Tape and Thinset: For cement boards, apply mesh tape over all seams and corners before applying thinset. The mesh tape reinforces the seams, preventing cracks and gaps. Spread a layer of thinset over the tape, smoothing it out with a trowel. Allow the thinset to dry completely before proceeding. Proper sealing and application of thinset ensure a continuous, waterproof barrier, protecting the niche from moisture infiltration.
3. Waterproofing Membranes: Choose between sheet membranes and liquid waterproofers for additional protection. Sheet membranes should be cut to fit the niche and applied over the backer board, ensuring that all seams are overlapped by a few inches. Smooth out any air bubbles to ensure full coverage. Liquid waterproofers can be applied with a brush or roller, covering the entire surface of the backer board. Allow the waterproofing membrane to dry as per the manufacturer’s instructions before proceeding with tile installation. Waterproofing membranes protect the niche from water damage and mold growth.

Tile Installation:

1. Aligning Tiles: Begin tiling by aligning tiles within the niche and matching them with the existing wall tiles. Use tile spacers to maintain consistent gaps between tiles and ensure that they are aligned properly. An even alignment will create a professional and cohesive look, blending the niche seamlessly with the rest of the shower.
2. Applying Tile Adhesive: Spread tile adhesive (thinset) on the backer board using a notched trowel, applying an even layer. The notched trowel creates ridges that help the tiles adhere securely to the backer board. Press each tile into the adhesive, ensuring good contact and a secure bond.
3. Placing and Spacing Tiles: Place tiles carefully, using spacers to maintain uniform gaps. Press tiles firmly into the adhesive, and use a level to check alignment. Adjust tiles as needed before the adhesive sets.
4. Cutting Tiles: If necessary, cut tiles to fit around the edges of the niche using a tile cutter or wet saw. Ensure that cuts are clean and precise to avoid gaps and uneven edges.
5. Grouting: After the adhesive has set (typically 24 hours), remove the spacers and apply grout between the tiles. Use a rubber float to spread the grout and press it into the joints. Wipe away excess grout with a damp sponge, being careful not to remove grout from the joints. Allow the grout to cure as per the manufacturer’s instructions.
6. Cleaning and Sealing: After the grout has dried, clean any grout haze from the tiles with a damp cloth. Apply a grout sealer to protect the grout from stains and moisture. Proper sealing ensures long-term durability and easy maintenance of the tiles.

Additional Considerations:

1. Checking for Leaks: After installation, test the niche for leaks by spraying water and checking for any signs of leakage around the edges. Proper sealing and waterproofing should prevent leaks, but it’s important to confirm before using the shower.
2. Allowing Drying Time: Allow adequate drying time for all materials, including adhesive, grout, and waterproofing membranes, before using the shower. This ensures that all components have been cured properly and reduces the risk of damage.

By following these detailed construction steps, you’ll create a well-built, functional, and aesthetically pleasing shower niche that enhances both the utility and style of your bathroom.
