How do i create a tiled niche or shelf in a shower? (2026)
Quick Answer
To create a tiled shower niche or shelf, you need to form a solid opening or support, waterproof it as part of the shower’s wet-area system, then tile it with the correct fall so water drains away instead of pooling. The most important part is not the tiling itself but keeping the waterproofing continuous and compatible with the rest of the shower build-up.
Overview
A shower niche or shelf can be very useful, but it sits in one of the wettest parts of the bathroom, so it must be built as part of the shower waterproofing system rather than treated like ordinary wall tiling. In practice, that means planning the position carefully, framing or supporting it properly, lining it with a suitable tile backer, waterproofing all faces, corners and penetrations in line with the membrane manufacturer’s instructions, and only then tiling it. The bottom of the niche or shelf should be formed with a slight fall towards the shower so water does not sit against grout lines or at the back edge. There are several ways to do it: build a framed niche between studs, install a factory-made prefabricated niche, or add a surface-mounted or corner shelf. For most DIYers, a prefabricated niche or a simple shelf is lower risk than cutting into a finished or load-bearing wall. If the shower is already waterproofed and tiled, adding a niche is usually not a good DIY job because disturbing the membrane can lead to hidden leaks. If you are unsure about framing, waterproofing compatibility, or local wet-area requirements, use a qualified professional.
Who this is for
Homeowners planning a new shower or major shower renovation, especially before tiling starts. It is less suitable for people trying to add a niche into a finished shower without rebuilding the waterproofing.
What you’ll need
- Tape measure and pencil
- Spirit level
- Suitable cutting tools for wall lining and tile
- Stud finder or wall inspection access
- Timber or other suitable framing/support materials if building a recess
- Tile backer board or other approved substrate for wet areas
- Compatible waterproofing system, including corner reinforcement where required
- Tile adhesive suitable for the substrate and tile type
- Tiles and trim pieces if using them
- Grout and sealant specified for wet areas
- Manufacturer instructions for the niche, backer board, membrane, adhesive and grout
Before you start
Check whether the wall is suitable. Do not cut into a load-bearing wall, a wall with plumbing or electrical services in the way, or a wall that cannot accommodate the niche depth. Confirm that all products in the assembly are compatible, and check local building and wet-area requirements before work starts. If this is an existing shower, be aware that cutting into finished tiling or membrane can compromise waterproofing.
Step-by-step
- 1
Plan the niche or shelf location
Choose a position that is convenient to reach but not directly where water will continually blast into it if you can avoid that. Mark out the proposed size based on your tile layout so the finished edges look balanced and you avoid awkward small tile cuts. For a shelf, decide whether it will be recessed, corner-mounted or supported between tiled walls.
Why: Good positioning improves usability and makes the niche easier to keep dry. Planning to the tile layout helps the finished work look intentional and reduces difficult cuts at the edges.
- 2
Check the wall structure and hidden services
Inspect the wall cavity before cutting. Locate studs, pipes, waste lines and cables, and confirm whether the wall framing can accept a recess without weakening the structure. If there is any doubt about structure or services, stop and get advice from a qualified tradesperson.
Why: A niche cannot safely go just anywhere. Cutting framing or hitting pipes or cables can create structural problems, leaks or electrical hazards.
- 3
Form the opening or install shelf support
For a built-in niche, cut the wall lining neatly and add solid framing around the recess so all sides are well supported. For a prefabricated niche, fit it exactly as the manufacturer specifies. For a shelf, fix or build a rigid support that is approved for wet areas and suitable for the tile load.
Why: Tiles and grout are not structural. The niche or shelf must be stiff and properly supported so movement does not crack the finish or break the waterproofing layer.
- 4
Line the recess with an approved substrate
Install the specified tile backer or other approved wet-area lining to all faces of the niche or around the shelf support. Shape the bottom so it has a slight fall outwards into the shower area rather than flat or backwards.
Why: A suitable substrate gives the membrane and tiles a stable base. The fall is critical because standing water at the bottom of a niche or shelf increases staining, mould risk and long-term moisture damage.
- 5
Waterproof the niche or shelf as part of the whole shower system
Apply the waterproofing system strictly in line with the membrane manufacturer’s instructions, including corners, joints, transitions and any reinforcement components required. Keep the membrane continuous from the main shower wall into and around the niche or shelf assembly. Let each product cure for the period stated by its manufacturer before covering it.
Why: The waterproofing layer, not the tiles, is what protects the wall structure. Continuity at corners and junctions is where many failures occur.
- 6
Tile the back, sides and bottom with drainage in mind
Dry-lay tiles first so cuts and grout joints are planned. Typically, tile the back and side faces in an order that keeps edges tidy, then set the bottom and top pieces while maintaining the slight fall on the bottom surface. Use a suitable trim or carefully finished tile edges where they will remain exposed.
Why: Dry-laying helps avoid poor alignment at the niche opening. Maintaining the fall during tiling ensures water still drains after tile thickness and adhesive are added.
- 7
Grout and seal movement joints correctly
After the adhesive has cured as directed, grout the tile joints with a grout suitable for wet areas. At changes of plane or where the manufacturer or system requires flexibility, use the specified sealant rather than hard grout.
Why: Rigid grout in movement-prone corners can crack. Proper treatment of movement joints helps preserve the finish and reduce water entry at vulnerable junctions.
- 8
Inspect and protect the finished niche or shelf
Check that water runs off the bottom surface, edges are fully finished, and there are no visible gaps, pinholes or cracked joints. Avoid heavy use until all products have fully cured in line with their instructions.
Why: A final check catches defects before the shower goes into regular use, when leaks are harder and more expensive to fix.
Why this works
A shower niche or shelf lasts when the structure is rigid, the substrate is suitable for wet areas, the waterproof membrane is continuous, and the finished surfaces shed water. Tiling only provides the wear surface; the waterproofing behind it is what stops moisture reaching the wall.
Common mistakes to avoid
- Cutting into a wall without checking for pipes, cables or structural framing issues
- Building the niche flat or with back fall so water pools inside
- Assuming tile and grout are waterproof enough on their own
- Mixing membrane, adhesive, backer board and sealant products that are not approved to work together
- Adding a niche into an already waterproofed shower without correctly reinstating the membrane
- Using hard grout in joints that should remain flexible
Troubleshooting
Water sits in the bottom of the niche or on the shelf
Check whether the finished surface has enough fall towards the shower. Minor issues may need retile work on the bottom piece; severe cases can require rebuilding the base of the niche.
Cracks appear at niche corners or shelf junctions
Look for movement, poor support or incorrect joint treatment. Remove failed material and repair using the membrane and jointing method specified for changes of plane.
Tiles around the niche sound hollow or come loose
This can indicate poor adhesive coverage, movement or moisture-related failure. Remove affected tiles, inspect the substrate and waterproofing, and rebuild as needed rather than simply regrouting.
Mould or staining keeps returning inside the niche
Improve drainage and cleaning first. If water is sitting in corners or behind failed sealant, remove defective material and repair the finish properly.

Alternatives
- Install a prefabricated recessed niche instead of building one from scratch
- Use a corner shelf fixed during tiling rather than cutting into the wall framing
- Create a half-height ledge or false wall in a full shower renovation to house toiletries
Pro tips
- Plan the niche size and position around your tile module before framing or cutting anything.
- If using large-format tiles, think about how the niche opening will affect cuts and visible joints.
- Choose a niche location that is easy to reach but not likely to be knocked by elbows.
- Use the membrane, adhesive and grout as a compatible system where possible.
- Keep the bottom surface simple and easy to wipe down; complicated mosaic layouts can trap residue.
Safety notes
- Turn off relevant services and confirm cable and pipe locations before opening any wall.
- Wear eye protection, gloves and a suitable dust mask when cutting board, tile or grout.
- Handle tiles carefully; cut edges can be very sharp.
- Do not alter structural framing unless you are qualified or have professional guidance.
Legal & regulatory notes
Wet-area waterproofing and bathroom alterations can be subject to local building rules and product-specific installation requirements. Requirements vary by location, so check local authority guidance and the waterproofing manufacturer’s documentation before starting.
What this guide does not cover: This guide covers the general process for creating a tiled shower niche or shelf, not project-specific engineering, plumbing relocation, electrical work, or the exact installation details for any particular waterproofing system or prefabricated product.
Cost considerations
A shelf is often simpler and cheaper than a custom framed niche. Costs rise if wall framing must be altered, plumbing or wiring must be moved, or a failed waterproofed shower has to be opened up and rebuilt.

Frequently asked questions
Can I add a niche to an existing tiled shower?+
Usually only with significant care and often not as a straightforward DIY job. Cutting into a finished shower can damage the waterproofing, and patch repairs are easy to get wrong.
Does the niche need waterproofing if it will be tiled?+
Yes. Tiles and grout are not the primary waterproof barrier. The recess or shelf area must be incorporated into the shower waterproofing system.
Should the bottom of the niche be level?+
No. It should have a slight fall towards the shower so water drains out rather than pooling.
Is a prefabricated niche better than building one myself?+
For many DIYers, yes. It can reduce some layout and forming errors, but it still has to be installed and waterproofed exactly as the manufacturer requires.
Can I use ordinary plasterboard behind shower niche tiles?+
Use only the substrate approved for your wet-area system and local requirements. In shower areas, an ordinary wall board may not be appropriate.
