15 Common Bathroom Floor Plans

Narrow 50-Square-Foot Bathroom Plan

At just 5 feet wide and 10 feet deep, this bathroom at first glance might seem unusually small and narrow. Instead, this is one of the most common bathroom plans. The length of the bathtub at the end dictates the bathroom's width. Nestling a 60-inch alcove tub into a bathroom from wall to wall means that the entire end of the room becomes a tub or shower enclosure. Sixty-inch tub/shower surround kits are designed precisely for this type of bathroom.

A long and narrow bathroom space can be difficult to plan around. One idea is to cap the end of the bathroom with a custom shower. This effectively shortens the length of the room and makes it easier to integrate the remaining features. This bathroom floor plan could work with a door almost anywhere along the open long wall. Ideally, you would want to avoid placing the toilet directly in front of the door unless absolutely necessary.

Features

• The 50-square-foot, 5-foot by 10-foot bathroom is commonly found in many homes.
• A shower or bathtub at the end maximizes the usage of the room's 5-foot width.
• The shape of the room makes a very long vanity and countertop possible. Two sink basins are easily accommodated. Another option is to have a single sink basin and a very long countertop.
• This layout can be adapted to feature a shorter vanity integrated with a tall linen closet.

Small 48-Square-Foot Full Bathroom

Small and smart are the names of the game in this bathroom layout, which effectively fits a toilet, tub, and sink—all in a mere 48 square feet. As tiny as it is, this bathroom is perfectly sufficient as a full main bathroom for a small house or as a guest bathroom for a larger house.

Features

• A supersize 72-inch bathtub occupies one end of the room.
• Sconce lights are located on either side of the sink.
• Lower plumbing and electrical costs are achieved by confining the water and drain lines and electrical lines along one wall.
• Using a pedestal sink rather than a vanity maximizes available space.
• Open wall to the right of the door can accommodate a small cabinet for towels.
• The room includes space for a bathtub or shower stall.

60-Square-Foot Full Bathroom

More floor space in a bathroom remodel gives you more design options. This bathroom floor plan can accommodate a single or double sink, a full-size tub or large shower, and a full-height linen cabinet or storage closet. And it still manages to create a private corner for the toilet. Instead of loading up the plan with more features, this bathroom layout implements smarter spacing of the basic features.

Features

• A spacious and airy feeling is created through the effective spacing of basic features.
• Careful planning provides space to accommodate a large shower if desired.
• A large vanity could be used for double sinks or one sink plus an extra-long countertop.
• The room could accommodate a partition wall and door to enclose the toilet area for privacy.

80-Square-Foot Bathroom With Tub and Shower

If you have the budget, this is an excellent bathroom floor plan that provides tons of flexibility. This plan features a shower stall and a bathtub, both of which are valuable for those busy mornings when two people need to bathe at once. The key to making this tight plan work is the corner shower stall with a rounded front, which maximizes space and allows for easier traffic flow.

Features

• A true primary bathroom is created in a limited space.
• The room offers two ways to bathe, either with a shower or a bathtub.
• A corner shower kit with a curved door saves space.
• A shallow cabinet for towels and other bathroom accessories can be located in the front space away from moisture.

Tiny 17-Square-Foot Half Bath

This bathroom plan is little more than a toilet and a sink, suitable for hand-washing and toilet duties only. It is an ideal half bath for short-term guests who are not spending the night. Such a small bathroom is known as a powder room, guest bathroom, or half bath.

Features

• A pedestal sink makes the best use of limited space.
• Plumbing fixtures confined to one wall make for simple plumbing work.

Basic Three-Quarter Bathroom

This rectangular room is fairly small, but it still manages to squeeze a toilet, sink, and shower into the space. Using a shower rather than a bathtub saves space, as showers generally have a smaller footprint.

Features

• Wide 36-inch vanity provides ample counter space.
• Shower sized at 36 inches by 36 inches visually balances the vanity.
• The careful arrangement prevents the toilet from facing the doorway.
• The layout provides room for the door to swing open.
• Use of a shower instead of a tub retains enough space for a cabinet.

Bathroom With Bump-Out Alcove for Tub

If you're fortunate enough to have a bump-out area, this layout is for you. Install a whirlpool or an oversized 72-inch bathtub in the window alcove area, tile the walls up to the bottom of the windows, and enjoy the light and view as you bathe.

Features

• This bathroom features a generous space for the bathtub as the focus of the room.
• The clever layout allows an awkwardly shaped space to become a unique bathroom haven.
• The space could accommodate a long, wall-to-wall vanity with double sinks.

Bathroom for an Awkward Room Shape

Sometimes the available space for a bathroom is not perfectly rectangular. It might be that a furnace closet, coat closet, or structural components impinge on the bathroom space. This 64-square-foot bathroom plan is an example of how to tuck all of the features needed for a full bathroom into spaces that are available.

Features

• An offset vanity makes efficient use of a long, narrow space.
• The bathing space is isolated from the toilet with an alcove wall.
• Space behind the entry door can be used for utilities, a coat closet, or other storage.

64-Square-Foot Bathroom Plan With a Private Toilet

In a home where the bathroom must be used by more than one person at a time, a walled-in private space for the toilet can greatly improve the space's functionality. This plan provides partition walls and a space-saving pocket door to create a toilet alcove. A conventional door wastes space because you need to account for its swing. Using a pocket door instead reclaims that space.

Features

• A long vanity and countertop make a double sink possible.
• The layout includes generous private space for the toilet.
• Use of a pocket door maximizes available space by eliminating door swing.

Three-Quarter Bathroom Plan With a Storage Room

Can you fit a toilet, tub, double sink, and floor-to-ceiling cabinet into a mere 64 square feet? While tight, this is possible, especially when privacy walls isolate the bathtub and toilet areas. One limitation of this bathroom layout is the entry door will swing into the cabinet.

Features

• A careful layout and a standard 60-inch bathtub allow space for a storage cabinet.
• The room allows space for a double sink.
• The bathtub and toilet receive privacy thanks to inner partition walls.

Large Bathroom Plan With Open Floor Space

The best of all worlds is a large bathroom space with relatively square dimensions. With this bathroom layout, it is possible to retain maximum open floor space by arranging the fixtures on opposite walls and using a shower rather than a full bathtub.

Open floor space is usually at a premium with bathrooms, and most homeowners prefer to use the space for additional, or larger, services. But a double-sink implies that more than one user will frequently be in the bathroom, often children. Floor space facilitates movement.

Features 

• This bathroom plan offers considerable open floor space.
• It includes all features and has both a bathtub and shower.
• An extra-wide vanity with double sink is included.

Fun and Simple Kids Bathroom

This large, square bathroom features a clawfoot tub, pedestal sink, and plenty of floor space for wrangling kids into the bathtub. Treat this wide open space as your canvas for fun and fanciful designs.

Features

• The clawfoot bathtub is a fun addition that kids love.
• There's plenty of space for a chair to create a comfy sitting area to use when keeping an eye on the kids.

Long Space for a Custom Shower

This bathroom floor plan uses the end of a narrow room for a custom tile shower. A clawfoot tub and a small vanity leave flexibility for the position of the toilet. The toilet could be tucked in between the end of the bathtub and the shower wall or positioned to the side of the vanity and the sink.

Features

• The room features both a clawfoot tub and a walk-in, custom tile shower.
• This bathroom layout provides flexibility in the positioning of the toilet.

Unique Double-Door Shower With an Exterior Exit

Not many homes can accommodate a bathroom floor plan that has a door leading outdoors from the shower. But with enough landscape privacy, this bathroom would be truly unique. It features a large frameless glass shower with an exterior door leading onto a deck.

Features

• The large glass shower has an exterior door, providing access to a deck or pool area.
• This layout gives you plenty of space near the vanity.

Bathroom With Alcove Tub and Surround

Many bathrooms make use of a design in which the bathtub/shower is recessed into a framed alcove, with the three alcove walls covered with surround panels. An advantage of this layout is the room retains open floor space, which is ideal for family bathrooms.

Features

• The alcove tub allows for a wide open floor area.
• The long wall adjacent to the door could accommodate a linen cabinet or other storage units.
