Wet Room Bathroom Layouts for Small and Mid-Size Bathrooms

A wet room isn’t just a shower without a threshold open to the rest of the bathroom; it’s a design where the entire floor is waterproof and sloped, so water flows to the drain from anywhere in the space. This single modification enables many different bathroom floor plans that a conventional shower enclosure cannot achieve. The five wet room layouts I’ve created here range in size from a compact 5×8 to an 8×10. All of them answer the same question in different ways: how much of the room will be wet and how much will remain dry. With each, you’ll want to watch the position of the enclosure glass and the drain placement, since these two choices do the main work of controlling water. Each plan below keeps the drain on the far wall from the entry, since this is the best way to prevent water from seeping toward the door.

5×8 Classic Wet Room Layout

The shower extends the full width of the room, turning the narrow end of the small bathroom into the standout feature of the room.

A room that is eight feet wide by five feet long is typical for a second bathroom in most houses. These often have a smaller 32-inch corner shower that usually ends up being pressed up against the back wall. This layout takes the opposite approach by assigning the full 60-inch-long side along the left side of the room to the shower. The enclosure spans wall to wall, and the drain is placed at the furthest point inside. One 36-inch pane of glass divides the wet area from the dry area, and instead of opening a door, you enter past the side of the glass, through a 24″ gap. This setup helps the room seem to be a single space rather than two separate zones.

The dry area includes the other features with a single sink, a 24″ x 24″ vanity in the top corner, and a toilet underneath it. Since the vanity is only 24 inches deep; you end up with just one sink and very little counter space. There’s a 30-inch sliding entrance door that opens into the dry section. Doors opening onto a wet floor are the reason bath mats end up getting soaked and are not great for everyday use. If a wet room isn’t the direction you want, there are other ways to lay out a 5×8 bathroom. 

Dimensions:

• Room size: 8′ x 5′ (96″ x 60″)
• Shower zone: 40″ x 60″, full room depth
• Dry zone: 56″ wide
• Vanity: 24″ x 24″
• Toilet clearance: 3′ x 4′
• Entry door: 30″

Design Tips:

• Lay the floor tiles in one direction across both areas so that the pattern isn’t broken at the glass panel, which can make it appear like two smaller rooms instead of one.
• Fit the shower controls to the entry side of the wet area so that you will be able to start the water by reaching in without having to stand under or enter the shower.
• Instead of choosing cabinet doors for the vanity, opt for a sink that’s mounted on the wall. This will allow you to see the floor beneath the vanity and recover some of the visual space at the expense of storage.

6×8 Bathroom With Tub Inside Shower Floor Plan

To fit both a bathtub and a shower in a bathroom this size, you’ll need to place the soaking tub inside the wet area.

Trying to have a separate tub and a separate shower in a 6 by 8 bathroom with a toilet and vanity is challenging. The solution is to place the 30-inch by 60-inch freestanding soaking tub directly into the wet area and have the shower rain over both. The left wet area measures 54 inches and has the drain running along the top wall behind the tub. A 12-inch strip above the tub and open floor space around it mean you can stand and shower beside it without having to climb in each time.

The dry section measures 42 inches in width and has the toilet situated at the top with a space of 3 feet by 4 feet, and the vanity underneath is 24 inches by 42 inches.  The sliding entry door is on the right wall, giving a straightforward flow so that you enter into the dry area and only move into the wet section when you intend to. The problem with this design is the time it takes to dry and increased maintenance. Because the freestanding tub sits in an open wet area, the surrounding floor stays wet longer than it would with a curb-mounted shower. To help combat this, you need to install more than adequate ventilation to ensure it can dry out after each use to prevent moisture-related issues.

Dimensions:

• Room size: 8′ x 6′ (96″ x 72″)
• Wet zone: 54″ wide
• Dry zone: 42″ wide
• Soaking tub: 30″ x 60″
• Vanity: 24″ x 42″
• Toilet clearance: 3′ x 4′
• Entry door: 30″

Design Tips:

• Choose a bathtub that has a slim rim and no deck, since every inch of the tub’s edge is ground that you can’t stand on when showering.
• Put the exhaust fan directly over the wet zone, since moisture needs to be tackled here so it doesn’t become a problem.
• Use a handheld on a slide bar in conjunction with the fixed head, since rinsing down the tub is a daily task in this arrangement and it would be awkward if you had the fixed head alone.

6×10 Long Wet Room Design

A long, narrow bathroom like this does well when the shower is placed at the end so it can accommodate a large vanity upfront with the toilet in the middle.

In older houses and in extensions, long and narrow bathrooms are common and can often be a challenging room to use in the house. If a room measures six by ten and has a door at one end, it creates a corridor with fixtures running along one side. This new arrangement overcomes this by allocating the far 48 inches of width to the shower and the remaining 72 inches of floor space to the toilet and vanity.

The dry area extends along the wall the left-hand side with a vanity that measures 24 inches by 60 inches. In the center of the room straight up from the entry is the toilet with 30 inches by 60 inches of clearance. The glass shower partition on the wet side provides an opening of 30 inches near the entry, with a width that is ample for walking through easily. The linear drain is located on the far right side, at the point most distant from the entrance. This way the water has further to go before it comes anywhere near the threshold. 

Dimensions:

• Room size: 10′ x 6′ (120″ x 72″)
• Wet zone: 48″ wide, full room depth
• Vanity: 24″ x 60″
• Toilet clearance: 30″ x 60″
• Partition opening: 30″
• Entry door: 24″

Design Tips:

• Instead of using two small mirrors, hang a full-height mirror over the vanity. In a narrow room like this the mirror does more to create the impression of width and can increase brightness as well to avoid the corridor feel.
• Fit a linear drain to the far wall rather than having a central drain. Since the room is so long it requires a single uniform slope, and a linear drain allows the tiles to have a pitch in just one direction.
• Light the shower end on its own switch. The further end of a long room becomes dim very quickly, and a bright wet area draws the eye all the way down.

7×9 Bathroom With Dedicated Wet Shower Bay Layout 

The shower room along the back is large enough to allow two people to use it at the same time and creates an impressive focal point from the entry.

 

 

 

A 7×9 wet room offers a little more space for some of those luxury features like a larger shower enclosure. With this design you have space enough for a proper 48″ x 72″ shower area on the left side, taking up the full depth of the room. Inside the enclosure is a window on the outer wall to provide daylight and help brighten the room. The glass partition leaves a 26-inch opening, which is slightly tighter than the one in the 6×10 plan, and deliberately made so to help limit water spray into the space.

The 60-inch dry side has a lot of usable space, and is primarily split between the toilet area up top and the single sink vanity on the lower side with the entrance coming from the middle right. The vanity measures 24 inches wide by 48 inches long, positioned along the lower wall. There is a small linen closet beside the vanity, but with only a small 12″ opening, it could be challenging to access this area.

Dimensions:

• Room size: 9′ x 7′ (108″ x 84″)
• Shower bay: 48″ x 72″
• Wet zone: 48″ wide, full room depth
• Dry zone: 60″ wide
• Vanity run: 48″ x 72″
• Partition opening: 26″

Design Tips:

• Use the window in the shower area to promote natural light and use frosted or reeded glass that provides privacy.
• For the linen closet, use open shelving so it’s easy to access in the limited space, or just put the door above the vanity surface.
• For a more luxe feel, install a foldable bench in the lower wall of the enclosure for sitting down and shaving legs.
• Carve a recessed niche out of the partition wall rather than the exterior wall, since an insulated wall is the wrong place to take storage from.
• Use an attractive quartz slab or tile across the shower to act as a focal point as you entry the bathroom.

8×10 Spa Bathroom With Wet-Room Design And Separate Water Closet Floor Plan

This bathroom benefits from its large shower across the back, with a dual vanity and private water closet near the entry.

With a bathroom measuring eight by ten, you have more room to move and get luxury features like a larger walk-in shower, private toilet room, and double vanity. This plan involves extending the wet area across the whole upper area of the room, making it 48 inches deep and 96 inches wide, and includes a linear drain along the back wall and a large window. The 26-inch gap into the enclosure is a bit off-center, which means that when you walk from the entrance door, you go straight through the dry section and end up in the shower; you can’t go around the vanity or cut past the toilet door.

Since the full-width wet zone requires more waterproofing and more tiles than the smaller plans, allow for this in your budget. In this layout, the work of installing the membrane beneath the floor changes from being a minor detail to becoming a large expense if not done first.

Underneath that, the room divides into three sections: there is a double vanity measuring 24 inches by 72 inches on the left, an open walkway down the center, and on the right an enclosed water closet with 36 inches by 66 inches of clearance space. It is that enclosed section that enables two people to be in the room at the same time with no one having to wait for anyone else.

Dimensions:

• Room size: 8′ x 10′ (96″ x 120″)
• Wet zone: 96″ wide x 48″ deep
• Dry zone: 72″ deep
• Double vanity: 24″ x 72″
• Toilet clearance: 36″ x 66″
• Partition opening: 26″
• Entry door: 30″

Design Tips:

• Put a bench at the left end of the wet area since the area is 48 inches deep and allows for one, and a wet room with a seat feels much more luxurious.
• Provide the water closet with its own exhaust fan and light switch since air needs to pass through a closed-off area in a humid room.
• Heat the floor in the dry area at the very least, since large format tile underfoot feels cold, and you’ll notice this every morning in a room of this size.

Picking the Right Wet-Room Layout

Before you decide on a layout, you must ensure that you follow the minimum dimensions to be code compliant. The shower compartment is the one that can surprise people, since the IRC requires a minimum interior area of 900 square inches with no dimension less than 30 inches. A sloped ceiling or a protruding valve may cause a plan to fail even if it looks all right in the other dimensions. If your room is irregular, another option is a minimum dimension of 25 inches, provided the compartment has a total area of 1,300 square inches. You also need 24 inches of clear floor in front of the opening.

The toilets each have their own numbers, and all the floors above take them into account. There must be a distance of fifteen inches from the center of the bowl to any wall, sink, bath, or glass panel, and 21 inches of clear space in front. Measurements should be taken from the finished surfaces, not the studs, since the tile and drywall use up that space quickly.

As for the wet area itself, the shower floor slopes by a quarter of an inch per foot towards the drain, the membrane underneath the tiles must meet ANSI A118.10, and true curbless entrance is achieved by recessing the subfloor not just by removing the curb. That same detail is what makes these plans work as barrier free and roll-in shower plans.

Two others are omitted. The ventilation rate is 50 cfm when the switch is used or 20 cfm when it is running continuously, with the ducts leading outside and never going into the attic. As for the tile that you’ll walk on when it’s wet, it should have a minimum DCOF of 0.42 according to ANSI A137.1. This requirement is more important here than anywhere else in the house since in a wet room the entire floor is the shower floor.

Since local regulations can differ, be sure to compare them with those of your local building department before starting your remodel work. To try out your own dimensions first, open our free bathroom layout planner and drag the fixtures around.
