Whether you’re a seasoned DIYer or tackling this project for the first time, you’ll gain valuable insights to help you create a beautiful and practical addition to your shower space.

Preparing the Wall and Framing the Shower Niche

Before installing a shower niche, it is essential to carefully prepare the wall where the niche will be placed. Begin by identifying the optimal location on the shower wall, considering accessibility, height, and avoiding interference with plumbing or electrical wiring. Use a stud finder to locate framing studs and mark their positions. Ideally, the niche should be centered between studs to minimize structural alterations.

Once the location is selected, use a pencil and a level to outline the exact dimensions of the niche on the wall. Double-check measurements with the niche unit or pre-fabricated box to ensure a precise fit. If the wall is already tiled, you may need to remove tiles within the outlined area carefully without damaging surrounding tiles.

The next step involves cutting the wall to create an opening for the niche. Use a drywall saw or oscillating multi-tool to cut along the marked lines. When cutting into a stud wall, you might need to remove or modify part of the stud framing to accommodate the niche depth.

To maintain structural integrity after cutting into a stud wall, install a horizontal header and footer (blocking) between the adjacent studs. This framing supports the niche and provides a solid surface for attaching it. Use treated lumber if the niche will be exposed to moisture.

Installing the Shower Niche Box

With the opening prepared and framing in place, the shower niche box can be installed. The niche can be a pre-formed plastic or metal box or a custom-built niche assembled from cement backer board.

Position the niche box into the opening, ensuring it is flush with or slightly recessed from the finished wall surface to allow for tile thickness. Use shims to level the niche as needed. Secure the niche by screwing it into the framing or blocking through the flanges or mounting holes provided on the box.

A waterproofing membrane must be applied around the niche to prevent water infiltration. This is critical for preventing mold and water damage behind the wall. Options for waterproofing include:

  • Applying a liquid waterproofing membrane over the niche edges and surrounding wall area.
  • Using waterproofing tape along the seams between the niche and wall.
  • Installing a waterproofing liner behind the niche.

Ensure that all seams and corners are thoroughly sealed and that the waterproofing extends beyond the niche perimeter onto the wall.

Finishing the Shower Niche Installation

After securing and waterproofing the niche box, the next step is to prepare the niche for tile installation. Cover the niche interior and surrounding wall area with cement backer board if not already done. Fasten the backer board securely, and tape the seams with fiberglass mesh tape embedded in thin-set mortar to create a smooth, stable surface.

When tiling the niche, use waterproof tile adhesive or thin-set mortar suitable for wet environments. Select tiles that match or complement the shower wall tiles. It is common to tile the niche interior with mosaic or decorative tiles to create a visually appealing accent.

Ensure that the grout used is water-resistant and sealed after curing to maintain the waterproof integrity of the niche.

Step Key Considerations Materials/Tools Needed
Wall Preparation Locate studs, mark niche position, cut opening carefully Stud finder, pencil, level, drywall saw
Framing Install blocking for support, maintain wall integrity Treated lumber, screws, drill
Niche Box Installation Position flush/recessed, secure to framing, waterproof edges Shims, screws, waterproofing membrane or tape
Finishing Install backer board, tape seams, tile niche interior Cement backer board, mesh tape, thin-set mortar, tiles, grout

Planning and Preparing the Shower Niche Installation

Proper planning and preparation are essential to ensure a successful shower niche installation. This phase involves selecting the niche size and location, verifying wall cavity dimensions, and gathering necessary tools and materials.

Begin by determining the optimal location for the niche within the shower wall. Consider the height and reachability, typically between 48 to 60 inches from the shower floor, and ensure it aligns with plumbing and structural elements behind the wall.

Next, verify the wall cavity dimensions to accommodate the niche. Most niches fit between standard 16-inch on-center studs, but confirmation with a stud finder and inspection behind the wall is crucial.

Material Needed Purpose
Shower niche kit or custom waterproof backing Forms the niche cavity and provides waterproofing
Waterproof membrane or liquid sealant Prevents water infiltration behind the niche
Cement backer board Durable, moisture-resistant substrate for tile
Tile and grout Finishing materials for the niche surface
Silicone sealant Seals edges and corners to enhance waterproofing

Essential tools include a stud finder, level, measuring tape, pencil, utility knife or reciprocating saw, drill, and trowel for mortar application. Confirm all materials and tools are on hand before commencing the installation.

Cutting and Framing the Shower Niche Opening

Accurate cutting and framing establish the niche’s structural integrity and ensure a neat, professional finish.

Mark the niche outline on the shower wall with a pencil, double-checking measurements and level alignment. Use a stud finder to avoid cutting through critical framing or plumbing.

When the outline is confirmed, carefully cut the drywall or cement board using a utility knife or reciprocating saw. Remove the cut section to expose the studs and wall cavity.

If the niche width spans between two studs, it may be necessary to add horizontal framing supports, known as blocking, to provide a solid mounting surface for the niche assembly.

  • Measure the niche height and width precisely.
  • Cut through drywall or cement board along marked lines.
  • Install horizontal blocking between studs if needed for support.
  • Ensure the opening is square and level before proceeding.

Use a level to verify that the framing is perfectly vertical and horizontal, as any deviation will affect tile alignment and overall appearance.

Waterproofing the Niche Cavity

Proper waterproofing is critical to prevent water damage and mold growth behind the shower wall.

Start by installing cement backer board around the niche opening if it is not already in place. Secure it firmly to the studs and blocking, using corrosion-resistant screws spaced per manufacturer recommendations.

Apply a waterproof membrane or liquid waterproofing product over the backer board and niche cavity. This layer must extend beyond the niche perimeter to integrate with the shower’s existing waterproofing system.

  • Use a paintbrush or roller to apply a liquid waterproof membrane evenly.
  • Seal all seams and corners with waterproof tape or fabric embedded in the membrane.
  • Allow the waterproofing to cure fully according to product instructions.

Verify the waterproofing layer is continuous and free of pinholes or gaps. This step is essential to maintain a moisture-tight barrier behind the tile.

Installing the Shower Niche and Tile

With waterproofing complete, the niche installation can be finalized by setting the niche unit and tiling.

Position the prefabricated niche or custom-built frame into the prepared cavity. Ensure it fits snugly and is level on all sides. Secure the niche to the blocking or studs using screws as specified by the manufacturer.

Apply thin-set mortar to the back and edges of the niche, embedding it firmly into place. Use a trowel with the correct notch size for the tile thickness to ensure adequate adhesion.

Tile Type Recommended Trowel Notch Size
Standard ceramic or porcelain (4-6 mm thick) 1/4″ x 1/4″ square notch
Large format tile (over 12″ x 12″) 1/2″ x 1/2″ square notch
Natural stone 1/2″ x 1/2″ square notch or larger

Begin tiling inside the niche, starting with the back panel, then the sides and bottom. Use tile spacers to maintain consistent grout lines. Cut tiles as necessary with a wet saw or tile cutter for precise fits.

After the tile sets, apply grout evenly, pressing it into the joints and wiping excess with a damp sponge. Once cured, seal grout lines and apply silicone sealant along niche edges to prevent water infiltration.
