Small bathrooms are one of the most challenging and rewarding spaces to work in. The constraints are real — you have limited square footage, often awkward layouts, and the expectation that the room should still function for everything a full-sized bathroom does. But after overhauling dozens of small bathrooms in older homes, condos, and tight floor plans, I’ve learned that the right design decisions can make a 40-square-foot bathroom feel twice its size.
Here’s what I actually do — and recommend — when working with a small bathroom.
Start with the Layout Before You Think About Finishes
Most homeowners jump straight to picking tile and paint colors. In a small bathroom, that’s the wrong starting point. Layout is everything. Before you commit to a single finish, evaluate whether the existing arrangement of toilet, sink, and shower or tub is the most efficient use of the available space.
In many older homes, the plumbing was roughed in during an era when bathrooms were purely utilitarian. That means there may be a far better configuration available to you with a modest plumbing adjustment. I’ve repositioned a toilet by just 18 inches and gained enough room to install a proper double-entry shower rather than a cramped tub surround — transforming the entire character of the space.
If moving plumbing is outside your budget, focus on how the door swings. A standard inward-swinging door in a small bathroom is a perpetual problem. Converting to a barn door, a pocket door, or a swing-out door can reclaim two to three square feet of usable floor space, which is enormous in a tight room.
Make the Shower Work Harder
The shower is the most important decision in a small bathroom remodel. Replacing a builder-grade tub-shower combo with a custom walk-in shower — even a small one — is the single upgrade that transforms how a small bathroom feels and functions more than any other change.
A curbless shower with a frameless glass panel is my go-to recommendation for small bathrooms. The frameless glass allows the eye to travel through the space without visual interruption, making the room feel open. The curbless entry eliminates the visual step-break that compartmentalizes the floor. Together, these two choices make a room read as one continuous, larger space.
Niche shelving built into the shower wall is essential. Every recessed niche you add eliminates a rack, caddy, or shelf cluttering the shower floor or hanging from the showerhead — all of which visually shrink the space.
The Vanity Decision: Where Most People Get It Wrong
Standard vanities are too deep for many small bathrooms. A 21-inch depth vanity — the typical builder standard — eats significant floor space in a room that might only be 60 inches wide to begin with. Shallow-depth vanities at 16 to 18 inches are widely available and dramatically improve circulation in the space.
Floating vanities are one of my strongest recommendations for small bathrooms. Mounting the vanity off the floor exposes the floor beneath it, creating visual continuity that makes the room feel larger. It also makes cleaning significantly easier — a practical benefit that adds up quickly in a high-traffic bathroom.
For hardware and fixture sourcing in small bathroom projects, I’ve had good results with HanoDecor. Their wall-mount vanity options are well-constructed and the hardware lines are designed to complement modern minimalist aesthetics — which is exactly what small bathrooms benefit from. Clean lines and minimal visual weight are the goal, and the right fixture choice makes a real difference.
Tile Strategy for Visual Expansion
Tile makes or breaks the perception of space in a small bathroom. A few principles I follow consistently:
Large format tile on the floor reduces grout lines, which reduces visual busyness. I typically use 12×24 or 18×18 tiles in small bathrooms rather than the smaller mosaic tiles that were popular in older renovations. Fewer grout lines make the floor read as a single, expansive surface.
Running floor tile into the shower with no threshold — continuing the same material from room to shower — is one of the most effective spatial illusions in small bathroom design. When the floor is continuous, the room feels unified and larger.
Vertical tile patterns on walls draw the eye upward, emphasizing ceiling height rather than floor area. A stacked vertical subway tile or a tall, narrow format tile on the wall creates a sense of height that counteracts the tightness of a small footprint.
Light, neutral tones in tile and grout reflect light rather than absorbing it. I’m not saying you can’t use dark tile in a small bathroom — I’ve done it successfully — but it requires careful planning with lighting to avoid a cave-like result.
Lighting: The Most Underestimated Space-Maker
Small bathrooms are often poorly lit, and poor lighting makes them feel smaller and dingier than they are. This is one of the highest-value upgrades you can make because the cost is relatively low and the impact is dramatic.
Vanity lighting positioned at eye level on either side of the mirror — rather than overhead — eliminates harsh shadows and provides even, flattering illumination across the entire vanity area. Overhead lighting in a small bathroom should supplement side lighting, not replace it.
Recessed lighting in the shower is essential in any small bathroom remodel I do. A waterproof recessed fixture in the shower ceiling dramatically improves the feel of the shower and contributes to the overall light level of the room.
If your small bathroom has no natural light, consider a solar tube or skylight if the ceiling and roof configuration allow it. Natural light in a windowless bathroom is transformative, and I’ve done several installations in exactly those conditions with outstanding results.
Storage Solutions That Don’t Shrink the Room
Storage in a small bathroom needs to be vertical. Recessed medicine cabinets, tall linen towers, and above-toilet shelving make use of wall height rather than floor footprint. Every square foot of floor you protect adds to the open, spacious feeling you’re working to create.
Built-in niches outside the shower — recessed into walls for toiletries, towels, or decorative elements — serve the same purpose inside the shower and can be placed strategically to use framing cavities without consuming any floor space at all.
The Small Bathroom Mindset
Every decision in a small bathroom remodel should be made with one question in mind: does this add visual weight or reduce it? Visual weight is what makes small spaces feel cramped. Eliminate it wherever you can — through floating vanities, frameless glass, continuous floor materials, vertical tile, and recessed storage — and you’ll be consistently amazed at what a small bathroom can become.
