AvatarByColleen Barnes Shower Routine & Lifestyle

Creating a shower niche is a smart and stylish way to add both functionality and aesthetic appeal to your bathroom. Whether you’re renovating an existing shower or building one from scratch, a well-designed niche offers a convenient spot to store shampoo bottles, soap, and other essentials without cluttering your space. Beyond practicality, a shower niche can also serve as a subtle design element that enhances the overall look of your bathroom.

Understanding how to make a shower niche involves more than just carving out a space in the wall. It requires thoughtful planning to ensure proper waterproofing, structural integrity, and seamless integration with your shower’s tile or wall finish. With the right approach, a shower niche can transform an ordinary shower into a sleek, organized oasis that meets your daily needs.

In the following sections, we’ll explore the fundamental concepts behind creating a shower niche, including design considerations and essential preparation steps. Whether you’re a seasoned DIYer or a first-time renovator, this guide will equip you with the knowledge to confidently add this valuable feature to your bathroom.

Preparing the Wall and Framing the Niche

Before constructing the shower niche, it is essential to prepare the wall properly. This preparation ensures structural integrity and waterproofing, which are critical in wet environments like showers. Start by removing the existing wall material where the niche will be installed, typically drywall or cement board. Use a stud finder to locate the wall studs and mark their positions clearly.

Framing the niche requires building a sturdy box within the wall cavity. Use pressure-treated lumber or moisture-resistant framing materials to prevent future damage. The niche frame should be slightly smaller than the desired finished size to accommodate tile thickness and waterproofing layers.

Key points for framing:

  • Remove wall material between studs for the niche size.
  • Cut and install horizontal headers between studs to create the niche perimeter.
  • Ensure the frame is level and square.
  • Use screws rather than nails for a stronger hold.

Proper framing also provides a solid base to attach cement board or other backer boards, which will serve as a substrate for tiling.

Waterproofing the Shower Niche

Waterproofing is crucial to prevent moisture from seeping into the wall cavity, which can cause mold, mildew, and structural damage. There are several methods to waterproof a shower niche:

  • Liquid Waterproofing Membranes: These are paint-on or roll-on products that create a seamless barrier over the substrate. They are easy to apply but require careful attention to coverage and drying times.
  • Sheet Membranes: These are thin sheets of waterproof material applied over the niche walls and floor, often bonded with thin-set mortar.
  • Waterproof Backer Boards: Some backer boards come pre-treated or designed to resist moisture.

Steps to waterproof:

  1. Apply a waterproof membrane to the niche frame and surrounding wall.
  2. Seal all seams, corners, and screw holes with waterproof tape or mesh embedded in thin-set.
  3. Ensure the niche floor slopes slightly toward the shower drain to avoid water pooling.
  4. Allow all waterproofing materials to cure according to manufacturer instructions before tiling.

Installing Backer Board and Preparing for Tile

After waterproofing, the next step is to install the backer board inside the framed niche. Cement board or fiber cement board is preferred due to its moisture resistance and durability.

Installation tips:

  • Cut the backer board to fit snugly within the niche frame.
  • Attach the board using corrosion-resistant screws spaced approximately 8 inches apart.
  • Tape all joints with alkali-resistant mesh tape, then apply a thin layer of thin-set mortar over the seams.
  • Ensure the niche surface is smooth and flush with the surrounding wall.

Once the backer board is installed and seams are finished, the niche is ready for tile installation. A smooth, stable substrate ensures the tiles adhere properly and remain durable.

Utility Knife / Saw Cut backer board and framing lumber Use appropriate blades for clean cuts

Planning and Designing Your Shower Niche

Creating a shower niche begins with careful planning to ensure functionality, durability, and seamless integration with your bathroom design. Consider the following critical factors before cutting into your shower wall:

  • Location: Choose a spot that is easily accessible while showering, typically at chest to waist height. Avoid placing the niche directly in front of the showerhead to prevent water pooling inside.
  • Size and Shape: Standard niches range from 12 to 16 inches wide, 12 to 24 inches tall, and approximately 3 to 4 inches deep to fit standard tile thickness and backing materials.
  • Stud and Plumbing Layout: Use a stud finder to locate framing studs and avoid plumbing or electrical lines. Shower niches are often framed between studs, so knowledge of the wall’s internal structure is essential.
  • Waterproofing Considerations: Plan for a waterproof backer board and proper membrane installation to prevent moisture damage.

A typical design specification table might look like this:

Aspect Recommended Dimensions Notes
Width 12–16 inches Allows storage of standard shampoo bottles and soap
Height 12–24 inches Accommodates multiple shelves or tiers
Depth 3–4 inches Matches tile and backer board thickness

Preparing the Wall and Framing the Niche

Preparation involves safely removing existing wall material and constructing a stable frame to support the niche:

  1. Mark the Outline: Using a pencil and level, mark the niche dimensions on the shower wall, ensuring the lines are square and aligned with studs.
  2. Cut the Drywall or Cement Board: Using a drywall saw or oscillating multi-tool, carefully cut along the marked lines. Remove the cut section to expose the studs.
  3. Inspect the Stud Cavity: Verify the cavity is free of plumbing and electrical wiring. If necessary, reroute utilities before proceeding.
  4. Frame the Niche:
  • Install horizontal blocking between studs at the top and bottom of the niche opening. Use pressure-treated lumber or moisture-resistant wood.
  • Ensure the frame is flush with the existing studs to create a flat surface for attaching backer board.
  1. Install Backer Board:
  • Cut cement backer board to fit inside the framed niche cavity.
  • Attach securely using corrosion-resistant screws.
  • Seal joints with fiberglass mesh tape and thin-set mortar to create a smooth surface.

Applying Waterproofing and Membrane

Waterproofing is critical to prevent moisture penetration and mold growth behind the niche:

  • Choose the Right Waterproofing System: Options include liquid-applied membranes (e.g., RedGard), sheet membranes (e.g., Schluter Kerdi), or waterproof backer boards.
  • Apply Waterproofing to the Entire Niche:
  • Cover the backer board inside the niche with the chosen membrane, including the bottom, sides, and top.
  • Extend the membrane a few inches beyond the niche edges onto the surrounding wall area.
  • Seal All Corners and Joints: Use waterproof tape or mesh specifically designed for shower installations at corners and seams.
  • Allow Proper Drying Time: Follow manufacturer instructions to ensure the membrane cures completely before tiling.

Tiling and Finishing the Shower Niche

The final stage involves installing tile and finishing touches that enhance both aesthetics and functionality:

  • Choose Tile Consistent With Shower Walls: Use matching or complementary tiles for a cohesive look.
  • Cut Tiles to Fit Niche Dimensions: Use a wet saw to ensure clean edges; consider bullnose or trim tiles for niche edges.
  • Apply Thin-Set Mortar: Spread mortar evenly inside the niche cavity and on the back of each tile.
  • Set Tiles Carefully: Press tiles firmly into place, maintaining consistent grout lines using spacers.
  • Install Tile Shelf (Optional): A small ledge or shelf can be tiled into the niche bottom for added utility.
  • Grout and Seal: Once tiles have set, apply grout with a rubber float, wiping away excess. After curing, seal grout to protect against moisture and staining.
