A shower niche is a small detail that gets decided late and regretted early. It is framed before the walls close up, waterproofed as part of the shower assembly, and effectively permanent once tile is set. Getting the size and position right is a five-minute conversation at the right moment and a demolition job at the wrong one.
Here is what actually governs the decision.
Depth is set by the wall, not by preference
The most common question is how deep a niche can be, and the answer is decided by framing rather than by design.
A standard interior wall framed with 2x4 studs has a cavity about three and a half inches deep. Once backer board and waterproofing are added, the finished recess is a little shallower than that. It comfortably holds bottles laid on their side and standard-sized containers standing up; it will not hold a tall pump bottle facing forward.
If you want more depth, the wall has to provide it. A wall framed with 2x6 studs gives roughly five and a half inches. Alternatively a wall can be furred out — built forward from the existing framing — specifically to create depth for the niche. Both are decisions made before the walls close, not after.
There is one constraint worth naming early: what is inside the wall. A wall carrying supply lines, drain lines or vents may not have a clear bay where you want the niche, and an exterior wall brings insulation into the equation. In practice this is what moves a niche a stud bay left or right, and it is discovered during framing.
Width follows the studs
Studs are typically spaced sixteen inches on centre, which leaves roughly fourteen inches of clear space between them. A niche that fits in one bay is the simplest version: no structural change, no header, nothing to engineer.
A wider niche means cutting a stud and installing a header to carry the load that stud was carrying. That is entirely normal work, but it is work — and it is the difference between a niche that is essentially free during framing and one that is a small framing job.
Height is where you have the most freedom, because a niche is not carrying load vertically. A single niche around a foot tall suits one shelf of products. A taller recess, sometimes with a shelf dividing it, suits a shared shower where two people want their own space. Neither is more correct.
Placement: three things that actually matter
Out of the direct spray. A niche in the path of the shower head collects water on every shelf. Placing it on a side wall, or on the same wall as the controls, keeps it drier.
At a height you use. Roughly between chest and shoulder height for a standing shower. Low enough to reach without stretching, high enough not to bend. If the shower includes a bench, a second lower niche near it is often more useful than one tall recess.
With a slight slope on the shelf. A niche shelf pitched very slightly toward the shower drains rather than pools. This is a tiling detail rather than a framing one, and it is the difference between a shelf that dries and one that grows a ring.
Two smaller niches often work better than one large one — one at standing height for daily items, one lower for anything used seated or for a razor. The framing cost is similar.
How a niche relates to the rest of the shower
A niche is one of several places to put things, and it is worth deciding between them together rather than one at a time.
A bench is the other common option, and it is a different order of work. It has to be framed to carry weight, sloped so water runs off rather than sits, and waterproofed as an extension of the shower floor rather than as a feature on a wall. Where a shower is large enough and someone wants somewhere to sit or rest a foot, a bench earns its place — and a low niche beside it usually makes more sense than a tall one across the room.
A corner shelf set into the tile is the lightest-touch option, needs no framing change, and holds less.
A ledge — a continuous recess running the width of the wall — reads as a design line rather than a box. It needs a header along its full length, so it is the most framing-dependent of the options and the one most worth raising early.
None of these can be retrofitted cheaply. All of them are decided in the same conversation.
The detail that decides whether it lasts
A niche is a hole cut into the one surface in your house that has to stay watertight. Every added corner is another place a membrane has to be carried continuously, and it is why the waterproofing matters more than the tile.
That means the membrane runs into the niche and around every internal corner without interruption, the shelf is sloped, and the tile is set over an assembly that was already watertight before any of it went on. In our project gallery you can see this stage directly — niches framed and membrane carried into the corners, photographed before the tile went on, alongside the finished result.
That is also why the sequence cannot be reordered. A niche is framed at rough-in and waterproofed with the rest of the shower. Adding one after the tile is set means removing tile, opening the membrane, reframing, re-waterproofing and re-tiling. The decision costs almost nothing at framing and a great deal afterwards.
Finishing choices
The back. A contrasting tile, a slab offcut or a mosaic in the back of the niche is a common way to add a detail without adding complexity. A single slab piece has the practical advantage of fewer grout joints in the wettest small space in the room.
The edges. Mitred tile edges, metal trim profiles, or a stone sill are the usual options. Mitres look cleanest and are the least forgiving of a niche that was not framed square — one more reason the framing stage matters.
Lighting. A niche can take a low-voltage light, which needs to be planned at rough-in with the rest of the electrical. Like everything else here, it is easy before the walls close and disruptive afterwards.
Where this fits in the wider job
A niche is a detail inside a larger scope. It gets decided during the framing and rough-in stage of a bathroom remodel, at the same point as the shower pan, the valve position and anything else buried in the wall. If several rooms are changing at once, those decisions are best made together rather than room by room — the reason whole-home renovations run as one coordinated project.

Common questions
How deep can a shower niche be?
In a standard interior wall framed with 2x4 studs, the cavity is about three and a half inches deep, and the finished niche ends up a little shallower once backer board and waterproofing are added. That is enough for bottles laid on their side. A deeper niche needs a wall framed with 2x6 studs or a furred-out wall built for the purpose.
What is a standard shower niche size?
Width is usually set by the framing: studs at sixteen inches on centre leave roughly fourteen inches of clear space between them, so a single-bay niche lands near that. Height is a design decision rather than a constraint, commonly somewhere between a single shelf and a tall recess with a divider. A wider niche means cutting a stud and adding a header.
Where should a shower niche go?
On a wall that is not directly in the spray, at a height you can reach without stretching, and — where possible — not on an exterior wall or a wall carrying plumbing. The framing dictates more of this than the design does.
Can a niche be added after the shower is tiled?
Not without undoing the work. A niche is framed before the substrate goes on and waterproofed as part of the shower assembly, so adding one later means removing tile, opening the membrane, reframing and re-waterproofing. It is a decision that costs almost nothing during framing and a great deal afterwards.
Is a niche or a shower bench better for storage?
They solve different problems. A niche holds what you reach for standing up. A bench gives you somewhere to sit and a surface to rest a foot on, and is far more structural — it has to be framed, sloped and waterproofed like a small extension of the shower floor. Many showers end up with both.
