Rectangular Master Bathroom Layouts with Walk-in Showers (With Dimensions)

The rectangular shape is an easy one to use when designing a master bathroom; however, at the same time, it can be one of the easiest to waste. By setting up each fixture against the long walls, you can end up with a room feeling more like a corridor, whereas if you properly divide the space, you can achieve a calm, inviting atmosphere. All five rectangular master bathroom layouts I’ve created below position the walk-in shower in a different location. The plans range from 8’ x 12’ to 10’ x 15’, so you can see the small differences that come with gaining a few feet. Every floor plan provides the exact dimensions, including the door swings and the gaps in the walkway. The point you should keep in mind while browsing is that the vanity is 72 inches wide in three of the five models and 84 inches wide in the other two. Even more important than the counter size is the amount of space you have in front of the vanity so it’s a functional bathroom that you can easily use every day.

8×12 Compact Side-by-Side Master Bath Layout

This plan works by entering on the shorter wall directly to the double vanity, followed by the toilet and then the shower for a functional design.

This bathroom is arranged along a single axis, and to get in, you go through a door that is 32 inches wide in the short, 8 foot wall on the left side. The vanity measures 72 inches wide and is positioned against the lower wall as you enter. As you go from left to right, you’ll find the toilet on the left in its own 3 feet by 4 feet zone that’s opposite the vanity. On the back right side is the 36 inch by 60 inch shower with its entry door on the lower end. Since this enclosure size matches the standard size of a bathtub, it works well if you’re converting an old bathtub and shower combination to a shower so the plumbing doesn’t have to be moved very much. Instead of swinging into the shower pan the 26 inch hinged door swings into the room, which is important in the case where the pan is only 36 inches deep. There is a window to the left of the toilet, which really helps a narrow room feel bigger by letting in natural light that helps prevent the far end from looking dim and the entire design from looking like a corridor.

Dimensions:

• Room size: 8′ x 12′ (96″ x 144″)
• Vanity: 72″ x 22″, set 12″ off the entry wall
• Shower: 36″ x 60″ with a 26″ door
• Toilet alcove: 3′ x 4′, toilet centered 25″ off the shower wall
• Entry door: 32″
• Walkway: 44″ at the vanity, narrowing to 36″
• Clear floor beside the shower: 34″

Design Tips:

• If you already have the storage capacity you need, choose a vanity that is hung on the wall or one that floats, which gives the effect of greater width.
• Use a clear glass shower door rather than a frosted one, since one that is obscured can make the room seem approximately one-third shorter by blocking the view of the back wall.
• Place towel rods or hooks in the 34″ space next to the shower, as this makes it easy to reach them after exiting.

9×12 Bathroom With Rectangular Shower and Soaking Tub Floor Plan

All that is needed is an extra foot of width in this bathroom in order to fit a soaking tub and a walk-in shower.

This bathroom design divides the upper wall into three sections: on the left there is a toilet set in a 3′ by 4′ alcove, in the middle there is a fully enclosed shower measuring 42″ by 48″, and on the right, near the window, there is a 60″ by 30″ soaking tub. The 72″ double vanity is situated opposite on the lower wall, with the entry door situated on the bottom left side. Placing the shower in the center is unusual, but it is the best choice in the plan. By enclosing it on three sides, the tub has its own corner, and the toilet benefits from extra privacy.

There are 57 inches of clearance between the tub and the vanity, which is ample, and 42 inches between the shower and vanity. Since there is so much room, two people could use the bathroom at the same time without having to push past each other. The drawback is the shower itself, since it measures 42 inches by 48 inches and is a stand-and-rinse type, not one that allows you to sit and luxuriate if desired. So if you place more importance on long showers than on baths, you may want to consider another configuration.

Dimensions:

• Room size: 9′ x 12′ (108″ x 144″)
• Double vanity: 72″ x 22″
• Shower: 42″ x 48″ with a 26″ door
• Soaking tub: 60″ x 30″
• Toilet alcove: 3′ x 4′, 48″ deep
• Entry door: 32″, with 60″ of clear entry width
• Tub to vanity clearance: 57″

Design Tips:

• Tile the shower and the tub surround with the same material for a more cohesive look throughout both areas.
• Don’t use a shower curb and install a linear drain along the back wall. This way, the 42″ wide entry without a curb appears to be noticeably more spacious than one with a lip.
• Suspend the vanity mirrors as individual units, not as a single long panel. This breaks up the 12-foot wall and makes the sinks look separate for each person.

9×14 Long Rectangle Bathroom with a Corner Walk-in Shower Design

This design pushes the shower into the far corner, giving you a larger enclosure and a more luxurious experience.

 

The entry is a 32″ door on the left-hand side that opens into the bathroom, with the toilet to the left or on the upper side and the double sink vanity on the right or lower side, with a large 48″ x 78″ shower in the back corner. The enclosure has dimensions of 48 inches by 78 inches and is the largest in this range. The enclosure door is 32 inches wide and is hinged at the opposite end so that it swings out into the room rather than into the pan. This is the correct arrangement, and it is also wider than the shower doors on the other four plans, which are 24 to 28 inches wide. The shower head is mounted on the left wall, which causes the spray to go down the length of the enclosure rather than directly at the door. Furthermore, the 78 inches provide a space where you can stand while the water warms up.

Along the lower wall, there is the 84″ double vanity cabinet that is followed by open space that has room for a linen cabinet measuring 24″ by 30″. Given the room width of 9 feet, there is plenty of space for circulation: 56 inches between the toilet alcove and the vanity, 40 inches through the middle section, and 38 inches at the end of the shower to the cabinet.

Dimensions:

• Room size: 9′ x 14′ (108″ x 168″)
• Double vanity: 84″ x 22″
• Walk-through shower: 48″ x 78″, no door
• Toilet alcove: 3′ x 4′, toilet set 27″ off the shower wall
• Cabinet: 24″ x 30″
• Entry doors: two at 32″, one at each end
• Clearances: 56″ at the toilet alcove, 40″ mid-room, 38″ at the shower

Design Tips:

• Fix the showerhead by attaching it to the far left side so the spray is directed away from the opening, and slope the floor to lead water to a linear drain at the back.
• For a luxury add-on, install floor heating or a ceiling heat lamp above the shower.
• Move the shower door closer to the showerhead if you want to place a bench in back for sitting and shaving.
• Add a few wall niches in the long side of the enclosure for your bath products.
• Fit all the storage onto the vanity wall and use the 24 inch by 30 inch cabinet as your linen closet.

10×12 Split-Zone Master Bathroom Layout 

By keeping the middle empty, you have an easily accessible bathroom design that keeps the wet and dry areas separate.

A master bath stops feeling like a bathroom and starts feeling more like a room you can stretch out in when it is ten feet by twelve feet. This plan uses the extra width for a middle circulation area rather than fixtures, and a bigger shower. The entry is on the left side and opens into the center, with a toilet on the top wall in a 3-foot by 4-foot alcove that is 18 inches from the side wall and partly screened so that when you’re outside the door, you don’t look directly at it. There is a 72-inch double vanity positioned against the lower wall.

The 42-inch by 48-inch shower is situated in the far back corner with a 28-inch door. Below the enclosure is a linen cabinet against the right wall for storing your bath essentials. If you look at the clearances, they measure 68 inches from the toilet to the front of the vanity and 46 inches across the middle to the shower. The open central area is the design’s feature; it’s where you towel off, and almost all bathrooms that feel good include one section of floor that serves no purpose like this.

Dimensions:

• Room size: 10′ x 12′ (120″ x 144″)
• Double vanity: 72″ x 22″
• Shower: 42″ x 48″ with a 28″ door
• Toilet alcove: 3′ x 4′, set 18″ off the side wall
• Linen cabinet: 18″ x 24″
• Entry door: 32″
• Entry to vanity clearance: 68″, center walkway 46″

Design Tips:

• Do not place a bench or a rug in the open middle that you have to walk around; instead, if you want a seat, extend a narrow one from the wall below the linen cabinet.
• Run the shower tiling up to the ceiling so it makes the enclosure look more stylish.
• Illuminate the vanity from the sides of the mirror, not just from above. Since there is 68″ of open floor space behind you, a single ceiling light will cause your own shadow to fall on the mirror.

10×15 Luxury Master Bathroom with a Separate Toilet Room Floor Plan

This design feels luxurious through its use of a freestanding tub, private water closet, and large shower enclosure.

 

Since it is 15 feet long, this bathroom floor plan includes space for the toilet to have its own door for privacy. The right end of the rectangular area is split up into two separate rooms: the shower enclosure measures 56 inches by 60 inches, and the water closet (toilet) is 34 inches by 60 inches. Each room is behind a 24-inch door, with the remainder of the area remaining unenclosed. There is a double vanity measuring 84 inches long, extending along the top wall, and is a full foot longer than the 72-inch counters found in the three smaller plans.

The freestanding tub measures 66 inches by 32 inches, and is set against the lower wall as a primary focal point, with 66 inches of open floor space between the front of the vanity and the tub. This arrangement makes the tub appear freestanding rather than stranded. The large corridor makes the room feel more high-end and offers room to change and walk through easily.

It’s worth mentioning the two 24-inch doors since they are narrow. Although the code minimums differ, 24 inches is a tight width for a toilet room and also makes it difficult to move a laundry basket through. If you are able to borrow four inches from the shower wall to have a 28-inch door in the toilet room, then do so.

Dimensions:

• Room size: 10′ x 15′ (120″ x 180″)
• Double vanity: 84″ x 22″
• Freestanding tub: 66″ x 32″
• Shower: 60″ x 52″ with a 24″ door
• Toilet room: 60″ x 52″ with a 24″ door
• Entry door: 32″
• Vanity to tub clearance: 66″, walkway past the tub 28″

Design Tips:

• If the wall permits it, fit a window or a skylight above the tub to allow in natural light and promote outdoor views.
• Match the door styles and the hardware of the shower and the toilet room. Two matching doors on the same wall will make it look styled and cohesive.
• Use the section of wall between the tub and shower for hooks and a towel bar.
