Tiny Bathroom Layouts That Maximize Every Inch

Tiny spaces can still be calm, functional, and beautiful, but they do require a layout that carefully looks at every inch to maximize space. In this guide, I’ve shared bathroom floor plans that squeeze comfort and usability into the smallest room sizes possible. You’ll find everything from 4’×8′ hall baths to 5’×7′ galley rooms and 6’×6′ square arrangements. In addition, you’ll see my exact placement for fixtures, how much clearance you need, and tips for placing different features like pocket doors, corner sinks, and storage. This way, your tiny bathroom looks intentional, has a better flow, and actually feels bigger when you use it.

5×5 Compact Bathroom With Comfortable Layout

With the shower and sink in opposite corners, and by adding a fold-away counter, this small bathroom plan preserves a center aisle, so it’s easy to maneuver in the compact space while remaining genuinely comfortable to use.

Floor Plan Details: As you enter on the right through the compact 24″ sliding door, you face the 19″×19″ corner pedestal sink on the lower wall with a fold-down countertop. The toilet shares the same wall as the 32″×32″ neo-angle shower. The result is a compact 25 sq ft design with a walkable aisle through the middle, measuring about 33″, so the room feels easy to move in despite its size.

Dimensions:

• Room size: 5′ × 5′ (25 sq ft)
• Shower: 32″ × 32″ neo-angle
• Corner lavatory: 19″ × 19″
• Door width: 24″ sliding
• Open center/aisle: 33″ diagonal clearance
• Toilet zone: 30″ wide with comfortable front clearance (indicated by the dashed area)

Design Tips:

• Choose a corner/triangular pedestal sink or wall-hung model to free up space and visually widen the room.
• Use a frameless glass neo-angle shower. Ensure the door opens toward the room and avoids running into the toilet.
• Install a fold-down counter at 34″ to 36″ high on solid blocking for use when needed.
• Add a towel rod between the shower and sink.
• Mount a mirror medicine cabinet above the sink and recess it into the wall if possible.
• Install one or two vertical sconces at the sink for shadow-free lighting.
• Use a sliding or pocket door to keep the interior free for maneuvering.
• Keep finishes light and continuous (use the same-tone tile on the floor and walls) to help the space appear larger.

Key Takeaway: This ultra-compact bathroom efficiently accommodates a corner shower, sink, and toilet, allowing for maneuverability in its minimal space.

4×8 Linear Efficiency Bathroom Design

With its shower, toilet, and vanity all lined up on one wall, this 4’×8′ “ linear bathroom keeps a streamlined flow that works for busy households .

Layout Description: As you enter through the compact 24″ inswing door, you’ll immediately see a shallow sink vanity niche measuring 18″×24″ on your right. As you continue down the straight aisle you’ll notice a small pony wall leading to the toilet centered in the middle of the room. At the end sits the 32″ x 48″ shower enclosure that takes up the remaining space. The shower’s glass door opens inside to keep the floor space clear. Because the shower, toilet, and vanity all line up along the same “wet wall,” the opposite side stays open, which help the narrow 4′ wide corridor to feel longer.

Dimensions:

• Room size: 4′ × 8′ (32 sq ft)
• Shower: 32″ × 48″ with an alcove style enclosure
• Vanity top: 18″ × 24″ (use an 18″ depth to keep passage clear)
• Door width: 24″ inswing door
• Clear passage from entry to WC: 24″
• WC bay width: 30″ (15″ from centerline to each side)
• Shower door/swing clearance: 24″ into the aisle

Design Tips:

• Keep all plumbing along one wall to cut costs and simplify construction.
• Use a wall-hung or 18″-deep vanity to max out the available grooming space. Use a storage vanity if you need a place for essentials.
• Add a recessed mirrored medicine cabinet to add storage without protruding into the vanity space.
• Choose a frameless glass shower with a sliding door to contain water and promote a larger feel.
• Add a recessed niche on the shower wall opposite the opening for soap and shampoo.
• Set the wing wall at partial height to add some privacy for toilet use.
• Mount towel bars/hooks on the open wall to keep linens within reach of both the vanity and the shower.
• Use a pocket or outswinging entry door to preserve the aisle space.
• Run larger-format tile lengthwise in the 8′ direction for a visually longer room.
• Adding a linear drain to the shower allows for a minimal curb with the use of a slight slope.

Key Takeaway: This linear bathroom arrangement efficiently makes a narrow space feel uncluttered and allows ease of movement.

6×6 Bathroom With Smart Corner Fixture Layout

Moving the shower, sink, and toilet into the corners allows this 6’×6′ “corner bathroom layout” to preserve an open center that helps the room feel bigger and more comfortable.

Layout Description: This square 6ft by 6ft bathroom pushes all of the fixtures to the corners so that there’s a center area where you can easily move throughout.  The entry door has a full-size 36″ inswing that opens to have you facing the shower. Inside each fixture is tucked into a different corner, with a 36″×36″ neo-angle shower occupying the top-left.  In the bottom-left  there’s a compact corner sink and the toilet is set on the same wall in the other corner at a slight angle for knee room and privacy from the door. Sightlines run diagonally across the room and there’s about 35″ from the shower opening to the front of the toilet.

Dimensions:

• Room size: 6′ × 6′ (36 sq ft)
• Shower: 36″ × 36″ neo-angle design
• Door width: 36″ inswing door
• Diagonal clear path: 35″
• Sink-to-toilet clearance: 29.5″

Design Tips:

• Use a rounded or wall-hung corner sink to free up floor area and allow for a larger aisle.
• Choose a frameless glass neo-angle enclosure and keep the hinged door opening into the room.
• Angle the toilet slightly, or use a corner tank model to shorten its projection and improve your legroom.
• Add recessed storage like a medicine cabinet over the sink.
• Install a niche or triangular shelf above the toilet for essential toiletries.
• Use water resistant flooring such as porcelain or ceramic tile, luxury vinyl, or waterproof laminate throughout.
• Keep finishes a lighter color and match the wall and floor tile so the room feels like one open square.
• Mount towel hooks on the door or the wall next to the shower.

Key Takeaway: By using corner fixtures, this bathroom frees up the space in the center to improve maneuverability.

5×7 Galley-Style Tiny Bathroom With Tub & Shower Combo Layout

By lining up the tub and shower combo on one side and the vanity and toilet on the other this 5’×7′ bathroom forms a galley style layout that offers a  full-size bathing experience in a tight space.

Layout Description: The entry to this galley-style bathroom is a space-saving pocket door or slider that has you facing down a center aisle with all of the fixtures on either side. A 30″×60″ tub and shower combo runs along the entire left wall so the “wet zone” is contained on one side. On the right wall, there’s a compact vanity niche followed by a half wall for privacy and then the toilet. Clearances are tuned to keep the corridor at least 24″ wide between the tub and vanity at the top, and widening to 32″ opposite the toilet so the area feels comfortable. 

Dimensions:

• Room size: 5′ × 7′ (35 sq ft)
• Tub/shower: 30″ × 60″
• Vanity top: 24″ × 18″ with a shallow depth to protect the aisle
• Center aisle clearances: 24″ tub to vanity space, and 32″ for the tub to toilet

Design Tips:

• Use an extended full, or half pony wall to add privacy to the toilet area.
• Choose a single basin wall-hung or 18″-deep vanity to preserve the passage space.
• Hang a wall mounted medicine cabinet for extra storage above the vanity with a built-in mirror.
• For the tub/shower, use a curtain or sliding bypass glass and not an outswing door to avoid blocking the walkway.
• Add recessed niches in the tub wall for bathing products and essentials.
• Consider a narrow shelf above the toilet for items.
• Run the floor tile lengthwise in the 7′ direction and keep grout lines a light color to elongate the room visually.
• Mount vertical sconces on either side of the sink’s mirror for shadow-free lighting.
• Install a strong, quiet exhaust fan to avoid humidity issues in the small room.
• If noise transfer isn’t an issue, or you have a bedroom suite, keep the pocket/slider, otherwise consider an outswing door.

Key Takeaway: A galley-style layout creates a visually balanced bathroom and makes everything easily accessible.

6×6 Square Space Saver Bathroom Floor Plan

This 6’×6′ square space saving bathroom design keeps the shower and sink on one wall and the toilet and a wall cabinet on the other to make the small room feel organized and open.

Layout Description: This bathroom keeps the shallow 30″×18″ vanity sink directly to the right as you enter the room through a sliding or pocket door. There’s a wall cabinet mounted above and to the right of the sink for daily essentials. On the opposite side of the door, there’s a 36″×36″ shower in the top-left corner. The toilet is located in the lower-left corner with a generous amount of space in front for access. Additional wall cabinet storage is available in the lower-right hand corner near the door for extra linens and toiletries. Since both the shower and vanity share the same wall on the top, it simplifies plumbing and keeps water splashes to one side.

Dimensions:

• Shower: 36″ × 36″ with a neo-angle entry
• Vanity top: 30″ × 18″ with shallow depth to preserve the walkway

Design Tips:

• Keep the vanity depth at 18″ or choose a wall-hung model to keep the aisle wide.
• Use a frameless neo-angle shower door, or a fixed panel with a swing to keep it clear from obstructions.
• Build a short partition between the vanity and shower as a half wall with glass above to block splashes and provide privacy.
• Use a tall wall cabinet about 12″ to 15″ deep in the bottom corner so it stores towels without crowding the space.
• Line the upper wall with a mirror medicine cabinet to better bounce light through the room.
• Add a quiet 80+ CFM exhaust fan to prevent moisture issues in the tight space.

Key Takeaway: This square bathroom layout offers a balanced design, that provides comfortable fixtures to a busy household.
