If you’re planning on designing a master bathroom, one of the things that is often at the top of the list is a double vanity and a spacious walk-in shower. However, sometimes if you’re dealing with space constraints, it may feel like it’s not possible. If you’ve got a room that’s 8 by 10 feet, or some awkward rectangular shape, it can get even more challenging. These five master bathroom layouts show you what’s actually possible when planning your floor plan with a double vanity and walk-in shower. Each plan solves the same formula a little differently, ensuring each fits a double vanity, a walk-in shower, and a toilet, and offers enough floor space to move around comfortably. The designs range from tight 80-square-foot compact bathrooms to a 144-square-foot spa setup with a private toilet room. The differences in how each one uses its space are worth exploring before you finalize any of your plans.

Floor Plan Details: This 80-square-foot space, measuring 8 feet wide and 10 feet deep, starts with a 32-inch entry door centered on the lower wall. As you enter you’ll find the space is divided into two zones: the vanity and storage side on the left and the toilet and shower on the right. The 60-inch vanity sits on the left wall, with a linen cabinet tucked into the upper-left corner, right above it. The toilet occupies the right wall, and the walk-in shower takes up the far right corner and measures 39 by 60 inches.
There is an approximately 35″ center walkway, which is somewhat tight but usable for two people to each have their own morning routines, as long as the morning schedule is somewhat staggered. It’s best in a one-at-a-time design for those who like their elbow room. For those who depend on extra storage, the linen cabinet tucked into the upper-left corner helps keep towels and accessories nearby, preserves the open feel of the center, and doesn’t impede on the shower’s entry path.
Dimensions:
Room size: 8′ x 10′
Vanity: 60″ W x 22″ D
Shower: 39″ x 60″
Toilet zone: 36″ W
Center walkway: approximately 35″
Entry door: 32″ W
Design Tips:
Use a frameless glass enclosure for the shower so it visually enlarges the space and keeps your eye moving all the way to the back wall.
Mount your vanity mirror at a full-width from wall to wall, so it makes the 60-inch vanity feel more abundant.
Keep the linen cabinet doors at a flush profile so their profile disappears into the wall.
9×12 Long Master Bathroom with Double Vanity & Oversized Shower
The long proportions give you a double vanity by the entry, a private water closet and an oversized shower.
Floor Plan Details: At 9 by 12 feet, this room has enough length to feel roomy and give you elements like a private water closet and a larger walk-in shower. As you enter through the 32-inch door on the lower end, you’ll find a 72-inch double vanity lining the entire left wall. The toilet sits in a private room to the right, and the far wall works as an oversized walk-in shower. The shower measures 48 by 108 inches, which takes up nearly the full 9-foot width of the room. There’s a bench along the right and a showerhead positioned on the opposite side with the glass entry in the middle.
The toilet nook works as a completely enclosed water closet, but could also use a half-wall or low partition if you want a more open feel and still maintain a degree of privacy without adding a full door. The 40 by 60-inch toilet zone gives comfortable side and front clearance and room below for additional storage. The central aisle measures about 48 inches at its widest point, which is comfortable to move through.
Dimensions:
Room size: 9′ x 12′
Double vanity: 72″ W x 22″ D
Shower: 48″ x 108″
Toilet zone: 40″ W x 60″ L
Shower bench depth: 14″ to 16″
Shower entry opening: 28″
Center aisle: approximately 48″
Entry door: 32″ W
Design Tips:
Take advantage of the full-wall shower by installing a rainfall head in the ceiling above the center, and have an additional standard wall-mounted head on the left. This way, two could potentially shower at once, which is inviting for couples or preferred for those wanting a different showering option.
Opt for a half-wall toilet enclosure at 4 feet tall if you still want semi-privacy, but a more open feel. At 4 feet, seated users are actually screened from the vanity mirror.
For a stylish look, consider a floating double vanity rather than a floor-standing unit. Lifting the 72-inch span off the floor makes the room feel longer and easier to clean.
10×10 Square Primary Bath with Corner Shower Layout
This square bath design pushes the shower, the toilet, and the vanity all into their own corners and opens up a surprisingly spacious center.
Floor Plan Details: The 10 by 10-foot square is one of the most practical master bath footprints you can have due to its versatility. It’s wide enough for a full double vanity, with enough left over space for a large shower, and a toilet nook. Having a footprint with equal sides provides symmetry and means you’re not fighting against awkward proportions. In this plan, you enter from the right through a 32-inch door and are immediately facing the 72-inch double vanity that runs along the left wall. The corner shower, measuring 48 by 48 inches, is right above the sinks in the upper-left corner. The toilet sits in the upper-right in a 40 by 48-inch area with a small half-wall for some extra privacy. This arrangement leaves a large, open center area, measuring roughly 3.5 to 4 feet, that sits between the vanity and the shower. For a 10 by 10 room, it feels spacious, and there is still an abundance of wall space for shelving, towel hooks, and bars.
Dimensions:
Room size: 10′ x 10′
Double vanity: 72″ W x 22″ D
Shower: 48″ x 48″
Toilet zone: 40″ W x 48″ L
Center circulation: approximately 3’6″ to 4′
Entry door: 32″ W (side wall entry)
Design Tips:
You may be able to upgrade the shower to 48 by 60 inches by shifting the toilet slightly for an extra foot of depth that can make a big difference in comfort and potential resale value.
Use a consistent large-format tile across the floor since it can visually unify the space and make it feel more expansive.
Add a recessed niche or shelving to the toilet corner to keep toiletries off the top of the tank, and avoid the need for a separate cabinet.
8×14 Narrow Wet Wall Primary Bathroom with Linear Shower Layout
By lining up all of the plumbing on one long wall, you keep costs down and get streamlined access to the double vanity, toilet, and a full-width linear shower in a row.
Floor Plan Details: This bathroom is long and narrow with proportions that work for you instead of against you. At 8 by 14 feet, the room’s fixtures run along the left, spanning from the double vanity at the entry end, the toilet in the middle zone, and the walk-in shower at the far end. The 32-inch entry door sits centered on the short bottom wall. You walk in and face the left wall, which does all the work. The 72-inch double vanity sits directly to the left as you enter, followed by the 3 by 4-foot toilet zone with a full 8-foot width shower, measuring 48 by 96 inches at the end. With this setup, the right wall stays clear with 74 inches of open walkway. The linear shower at the far end acts as a focal point that draws the eye as you walk toward it.
Dimensions:
Room size: 8′ x 14′
Double vanity: 72″ W x 22″ D
Toilet zone: 3′ W x 4′ L
Shower: 48″ x 96″
Open walkway: approximately 74″
Entry door: 32″ W
Design Tips:
Keep the right wall simple and easy to navigate with one floating shelf and a towel bar. Resist the urge to add a tall linen cabinet on that side, because it’ll shrink the walkway and potentially make the corridor feel narrow again.
Tile the shower from floor to ceiling with a large-format vertical tile as it draws the eye upward and forward along the full length of the room, giving a more alluring appeal.
12×12 Luxury No-Tub Spa Bathroom with Large Shower & Toilet Room
This plan earns its spa label by pairing a large walk-in shower and bench with a private toilet room, and an expansive 84-inch double vanity for a luxurious feel.
Floor Plan Details: This is the layout for someone who wants to feel like they’re entering their own luxe spa environment each day. At 144 square feet, spanning a 12 by 12 footprint, it gives you enough room to separate every function so it all feels roomy and inviting. You enter through a 32-inch door centered at the bottom and are oriented with a fully enclosed toilet room that sits behind a 28-inch door to your left and the shower enclosure to your right. As you continue in toward the back, there’s an 84-inch double vanity on the left and the entrance to the 48″ by 84″ walk-in shower on the right with a full-length bench running along the back.
The center circulation space is 52 inches wide, which is comfortable so that two people can use the room at the same time. The 84-inch vanity is wide enough for two full sink zones with usable counter space between them. This amount of cabinet space offers plenty of storage underneath and can be divided into a his and hers space. The enclosed toilet room elevates this design as it offers privacy from others as they go about their normal daily routines.
Dimensions:
Room size: 12′ x 12′
Double vanity: 84″ W x 22″ D
Shower: 48″ D x 84″ W
Shower bench: 14″ to 16″ deep, full shower length
Toilet room: 84″ W x 48″ L, door 28″ W
Shower entry opening: 28″
Center circulation: 52″
Entry door: 32″ W
Design Tips:
For more space, install the shower entry at the end of the glass panel closest to the vanity, not the far end.
Use the upper left corner for a small reach-in linen closet.
Ensure there’s adequate ventilation in the shower, especially if it is completely enclosed.
Light the different zones, such as the toilet, vanity, main walkway, and shower enclosure, so there is adequate lighting.
