Bathrooms are the one room where the 'buy less furniture' advice that works everywhere else doesn't really apply — there's a toilet, a sink and usually a tub or shower, and none of them are optional. Making a small bathroom feel bigger comes down almost entirely to what happens at eye level and below: sightlines, reflectivity and how much of the floor is actually visible.
A few of these are renovation-level changes. Most aren't — they're swaps you can make without touching plumbing or tile.
Swap the Shower Curtain for Something You Can See Through
A solid, opaque shower curtain or liner puts a visual wall across a third of a small bathroom. A clear or lightly frosted liner — or a glass panel if you're renovating — lets sightlines run all the way to the back wall of the shower instead of stopping at the curtain, which reads as noticeably more open even though the floor plan hasn't changed at all.
Mount the Vanity Instead of Boxing the Floor
A wall-mounted, floating vanity shows a strip of floor underneath it that a floor-standing cabinet covers completely. That visible floor does the same job it does in a living room — it reads as extra square footage the eye can register, even though it's really just a few inches of tile. It's a renovation-level change, but it's one of the highest-impact ones on this list if a bathroom remodel is already on the table.
Go Bigger on the Mirror, Not Smaller
The instinct in a small bathroom is often to keep everything modest in scale, including the mirror. That's backward. A mirror that spans most of the width above the vanity — or wraps the corner — reflects more of the room's light and makes the wall it's on nearly disappear. A small, medicine-cabinet-sized mirror in an already small bathroom just adds one more boxy shape to a room that doesn't have space for extra shapes.
Consider a mirrored wall behind the vanity only
Tiling or mirroring just the wall behind the sink, rather than the whole room, gets most of the benefit — more reflected light, a sense of depth behind the fixtures — without the maintenance and cost of mirroring an entire small room.
Use Large-Format Tile With Minimal Grout Lines
Small tile with lots of grout lines breaks the floor and walls into a grid the eye has to process, and that visual busyness reads as more square footage being divided up, not less. Larger-format tile, or a continuous material like large-scale porcelain, reduces the number of lines in the room and lets the actual floor space read as one uninterrupted area.
- Run the same tile from the floor onto a curbless or low-curb shower floor to remove another visual break.
- Choose a grout color close to the tile color rather than a high-contrast grout, which minimizes the grid effect further.
- Keep the tile pattern simple — a straight or slightly offset lay reads calmer than a herringbone or busy mosaic in a small footprint.
Get Light Off the Ceiling and Onto the Mirror
A single central ceiling fixture casts shadows under the vanity and the countertop edge, which visually shortens the room. Sconces mounted at eye level on either side of the mirror, or a light bar above it, light the room more evenly and remove those shadow lines — the same principle as layered lighting in a living room, just compressed into a much smaller space.
Common Mistakes in Small Bathrooms
- Choosing a dark, opaque shower curtain that visually cuts the room in thirds.
- Sizing the mirror to match the sink instead of the wall, which leaves it looking undersized for the room.
- Over-tiling with small mosaic tile throughout, adding more grout lines than a small space can absorb.
- Storing everything in a floor-standing cabinet instead of using wall-mounted or recessed storage that keeps the floor visible.
Frequently Asked Questions
Does a clear shower curtain actually make a bathroom look bigger?
Yes, more reliably than most small-bathroom advice. An opaque curtain functions like a wall across part of the room; a clear or lightly frosted one lets the eye see the full depth of the shower, which reads as more space even though nothing physically changed.
Is a pedestal sink better than a vanity in a small bathroom?
A pedestal sink shows more floor, which helps visually, but it gives up storage a floating vanity with drawers can provide while still showing floor underneath. For most small bathrooms, a floating vanity is the better trade-off.
What's the best tile size for a small bathroom?
Larger-format tile, generally 12x24 inches or bigger, tends to work better than small mosaic tile because it reduces the number of grout lines breaking up the floor and walls.
