5x7 Bathroom Floor Plans and Fixture Guide for Small Spaces

A 5x7 bathroom gives you 35 square feet to work with, which is enough for a full bath that feels good to use every day. It is not enough for mistakes.

A 5x7 bathroom is one of the most common footprints in American homes, especially in apartments, condos, and older single-family houses. The dimensions are tight enough that a single bad decision can make the whole room feel like a compromise. A vanity two inches too deep, a tub oriented the wrong way, or a door that swings into the toilet will each cost you the room. Fortunately, the constraints in a space this size are predictable once you know where to look.

What fits in 35 square feet

Before the layouts, a few numbers worth knowing. These are the clearances most building codes and design standards expect, and they're what separates a bathroom that passes inspection from one that gets flagged.

• Toilet: 15 inches minimum from the centerline to any wall or fixture, and 18 inches is better. 21 inches of clear space in front, though 30 inches is the recommended minimum.
• Sink: 20 inches of clear space in front. For a double vanity, plan on 30 to 36 inches of counter per sink.
• Shower: 30x30 inches is the absolute minimum interior dimension. 36x36 is more livable.
• Tub: Standard alcove tubs are 60 inches long by 30 to 32 inches wide. A 5-foot wall is exactly 60 inches, which is why the short wall of a 5x7 bathroom is the natural home for a tub.
• Door swing: A standard 30-inch door needs roughly 30 inches of clear arc, and that arc cannot overlap a fixture's required clearance zone.

A 5x7 bathroom has 60 linear inches on the short walls and 84 linear inches on the long walls. That's it. Every fixture has to earn its place on one of those walls.

Four 5x7 bathroom floor plans that work

Layout 1: Shower, toilet, and sink on one wall

Shower, toilet, and sink all sit on the same long wall. The door centers on the opposite long wall. This is the default good answer for a 5x7 bathroom floor plan, and contractors will quote it most competitively because every wet fixture shares one plumbing wall.

The corner shower sits at one end, typically 30x30 or 32x32 inches. The toilet goes in the middle with full 15-inch centerline clearance on both sides. The sink takes the remaining space on the other end. Because nothing is hidden behind a door or tucked into a corner, the room reads bigger than it is the moment you walk in.

This layout works in almost any 5x7 with the door on a long wall, the most common configuration in apartments and townhouses.

Layout 2: Alcove tub replacing the shower

This 5x7 bathroom layout keeps the efficient one-wall plumbing run of Layout 1 but swaps the corner shower for a full 60x30 alcove tub. The tub anchors the short wall, while the toilet and sink fill out the long wall. This is the right pick if resale matters, since many buyers still expect at least one bathtub in the home, and also if anyone in the household actually takes baths.

The tub eats the entire 5-foot wall, which leaves less flexibility elsewhere. The toilet centerline clearance is tighter here than in Layout 1, so the sink usually ends up as a compact 18 to 24 inch vanity. A wall-hung or pedestal sink can buy back a few inches of visual space if it feels cramped.

If you're torn between Layout 1 and Layout 2, the question isn't really shower versus tub. It's whether you'd rather have a more generous sink area or a proper bath.

Layout 3: Tub opposite an awkward door location

Not every 5x7 has the door on a long wall. Older homes, additions, and unusual floor plans sometimes put the door on the short wall or at an awkward corner. In this layout, the tub sits on the short wall opposite the door, while the toilet and sink stack on the remaining long wall.

The upside is that the door swing lands in the open floor area rather than into a fixture. The downside is what you see when you walk in: the toilet, head-on. A pocket door or barn door can help if the existing door location is fixed.

This layout is worth considering when moving the door would mean relocating a load-bearing wall or rerouting significant framing, either of which can add $3,000 to $8,000 to the project.

Layout 4: Double vanity with shower and toilet

Two sinks in a 5x7 bathroom is possible. It is not always advisable. The long wall is 84 inches, which allows for two 36-inch vanities side by side with 12 inches of breathing room, or two 30-inch vanities with 24 inches between them. Either way, the rest of the room still needs to fit on the remaining walls: shower or tub, toilet, and door clearance zone.

The numbers works on paper but the daily reality is tighter in a 5x7 space. Two people at the vanities at the same time will be standing shoulder to shoulder, and the storage per sink is limited because the cabinets are narrower. For couples who both get ready at the same time every morning, that can still be worth it. For most other households, a single wider vanity with double the storage is the more practical call.

How much does a 5x7 bathroom renovation cost

A full 5x7 bathroom renovation typically runs $15,000 to $35,000, with most projects landing between $20,000 and $28,000. The range depends on three things. The first is whether plumbing is being moved, since keeping fixtures on the same walls is meaningfully cheaper. The second is the material tier, from standard ceramic tile to large-format porcelain or natural stone. The third is whether any structural or electrical work is hiding behind the walls.

Set aside 10 to 20% as a contingency on top of the base budget. For a $25,000 renovation, that's $2,500 to $5,000 held in reserve for the things you can't see until demo starts: outdated wiring, corroded drain pipes, or subfloor damage under the old tub.

How to choose fixtures for a small bathroom

Once the layout is set, the fixtures do most of the work of making the room feel considered rather than cramped. Here's what actually matters in 35 square feet.

Toilets for a small bathroom

A standard toilet tank is about 28 to 30 inches deep from the wall. In a 5x7 bathroom, that depth eats into the clearance zone in front of the toilet. Two fixes work well:

• A compact or small-space toilet, which runs 25 to 27 inches deep. The difference sounds small. It isn't, when every inch matters.
• A wall-hung toilet, which mounts to the wall with the tank hidden inside it. These save 8 to 10 inches of projection and make the floor easier to clean, but they cost $800 to $2,500 more than a standard two-piece toilet and require a carrier system inside the wall, which adds labor.

Skip the high-tank or traditional-style toilets with extra-deep bowls. They read beautifully in a catalog and swallow floor space in person.

Showers and tubs for a 5x7 bathroom

For showers, the single biggest decision is glass versus curtain. A frameless glass panel makes the room feel twice as large because your eye travels to the back wall. A shower curtain visually cuts the room in half. Glass costs $800 to $2,500 installed depending on size and configuration, and in a small bathroom it's usually the best design dollar you can spend.

Consider a curbless or low-curb shower entry. It's a small detail that makes the floor appear continuous and the room feel larger, and it's also the easiest way to make the bathroom work for aging in place.

For tubs, stick with a standard 60-inch alcove tub unless you have a specific reason not to. Yes, freestanding tubs are beautiful, but they’re the wrong answer for a 5x7 bathroom. They need clearance on all sides and push every other fixture into a worse position. Deep soaking tubs in the standard 60-inch footprint exist and give you the spa feeling without the spatial penalty.

Vanities for small bathrooms

Depth matters more than width in a small bathroom. A standard vanity is 21 to 22 inches deep. A shallow vanity at 16 to 18 inches deep gives back three or four inches of floor space, which is often the difference between a room that feels tight and one that feels fine. Pair it with a vessel or semi-recessed sink if storage is a concern.

Wall-mounted floating vanities visually expand the floor, and the gap underneath is a useful place to store a laundry basket or step stool. They run 10 to 20% higher than freestanding vanities and require solid wall blocking that your contractor will add during framing.

In a 5x7 bathroom especially, one sink done well will beat two sinks done tight almost every time.

Storage in a small bathroom

A medicine cabinet recessed into the wall is one of the most underrated moves in small bathroom design. It adds three to four inches of usable depth without taking any floor space, because it lives between the studs. Flag it to your contractor during framing, since it's much harder to add once the drywall is up.

A tall, narrow linen tower 12 to 15 inches wide, tucked into an otherwise dead corner, gives serious storage without eating the room. Open shelves above the toilet are free square footage most people never use.

Tile and finishes for a 5x7 bathroom

Large-format tile at 12x24 inches or bigger has fewer grout lines, which comes across as a continuous surface and makes the room feel larger. Small mosaic tiles do the opposite. Use mosaics as an accent on a shower floor or a niche, not as the main wall or floor surface.

Light floors, light walls, and a single darker accent almost always work better than dark everything or light everything. The accent can be the vanity, a shower niche, or the hardware. A 5x7 bathroom with a dark floor and dark walls will feel like a cave. The same room with a light floor, white walls, and a walnut vanity will feel like a considered small space.

Keep hardware in one finish across the faucet, shower fixtures, towel bars, and door handle. The mixed-metal look that works in a larger bathroom reads as visual clutter at this scale.

Lighting for a small bathroom

Recessed ceiling lights plus sconces on either side of the mirror is the standard for a 5x7 bathroom. A single overhead fixture alone casts shadows straight down under the eyes, which is a problem for anyone who shaves or puts on makeup. Sconces at eye level light the face from the sides and solve that entirely.

If the bathroom has a window, protect it. Natural light is the single most effective way to make a small bathroom feel larger, and frosted glass or a good window treatment can handle the privacy question without giving up the light.

What to sort out before construction starts

A small bathroom renovation moves fast once demo starts. Most 5x7 bathrooms come together in three to five weeks, and any decision you haven't locked in by then will stall the contractor or trigger a change order.

Lock these down before demo:

• The exact layout, including where the door swings and whether it stays in its current location.
• Every fixture, with model numbers. Not "a wall-hung toilet" but the specific wall-hung toilet.
• Tile selections for the floor, shower walls, and any accent areas, with quantities ordered with 10% overage.
• Vanity, sink, and faucet confirmed and ordered. Vanities can have six to ten week lead times for anything semi-custom.
• The full electrical plan, including outlets, switches, lighting locations, and the ventilation fan.
• A clear scope document from your contractor that lists everything above, with line items for labor, materials, and any allowances.

The single most common reason small bathroom renovations go over budget is change orders mid-construction, and the most common reason for change orders is a decision that wasn't made before the walls came open.

Getting matched with the right contractor

A 5x7 bathroom is a small project by square footage and a complicated one by density. Every trade touches the same 35 square feet, and the sequencing has to be tight. This is a renovation where the contractor's experience with small bathrooms matters more than total years in business.
