Designing a more efficient bathroom often means taking down barriers and smoothing traffic flow. Can opening the shower to the rest of the room create a more efficient, luxurious-feeling space? Sweeten explores the possibilities of this intriguing approach.

Sweeten matches home renovation projects with curated general contractors, offering advice, support, and up to $50,000 in renovation financial protection—at no cost to the homeowner.

What is a wet room bathroom? 

A wet room is a bathroom that typically has no enclosure separating the shower or tub from the rest of the bathroom. All of the walls and the flooring are sealed against water, just like the surfaces in a typical shower stall. 

The main flooring of the wet room is on the same level as the shower floor. The section of the wet room where the shower is located has a floor with a sharp slope to aid with water drainage. The rest of the bathroom floor is sloped toward the same drain. But the floor slope is more gradual.

Because there is so much water, bathroom facilities such as the toilet and sink are either raised or are water-sealed.

Due to how wet rooms work, the function of the room is prioritized over the style. Subsequently, most wet room design is clean and spare.

Why are wet rooms so popular?

Frameless showers let in more light. These use sheets of thick, unframed glass to surround the shower in a wet room. They make the whole room lighter and airier. Since wet rooms are designed with excellent ventilation, they typically see less mold and mildew growth.Wet rooms are much easier to clean. There are no cramped enclosures to deal with, and the whole floor can be hosed down.Wet room bathrooms are ready for all phases of a person’s life. There are no steps or curbs keeping walkers and wheelchairs out of the shower area. The toilet area merges seamlessly with the shower, too. 

Pros and cons of wet rooms


The bathroom feels brighter and more spacious because it has fewer walls and barriers.
The floor is easy to clean—all water can be directed to a single drain.
Accessibility: there is no shower curb or bathtub wall to step over. Wet room designs comply with many aging-in-place design rules.
There’s less chance of mold, mildew, and water decay.
The bathing area does not steam up because it is not enclosed.

Splashes from the shower can go everywhere.
It’s best to have plenty of space, to keep the shower separate from dry areas.
In smaller bathrooms, dry areas need to be made water-resistant.
It can feel colder in the shower, since there’s no enclosure to hold in heat.
The need for more tile work may increase costs.
They can be acoustically loud and bright because of the open design and hard materials.
Most things stored in the bathroom need to be enclosed in water-resistant cabinets.

Features and special considerations

Shower enclosures: Many wet room bathrooms are built without any shower enclosures. However, you can opt for an open enclosure with no door. Or you can add a half-wall to minimize splashing.
Bathroom storage: Locating storage and linen cabinets outside of the bathroom is one way to deal with moisture. Another is to install water-resistant cabinets in the room.
Large wet rooms: If you have a big enough space, you may be able to store moisture-sensitive items in the bathroom without special cabinets. Radiant heating: You can install radiant heating in the floor even though the floor will see plenty of water. Special underfloor radiant heating kits are available.
Raised sink cabinet: Pedestal sinks or cantilevered countertops are ideal choices for keeping cabinetry off the floor.
Relocated heating register: Heating vents cannot be built into the floor. Either build the vents into walls or use another type of heating.

Wet room bathroom maintenance and cleaning

Homeowners may worry about installing wet room bathrooms on upper floors. Yet a professionally installed wet room is no different than locating a freestanding shower on an upper floor. The waterproofing methods are the same—just on a larger scale. Be aware that just like with any bathroom, a wet room could eventually spring a leak and require maintenance.

Wet room floors are easy to clean. You can clean the flooring with a mild floor cleaner and a rubber-bladed mop. Start on the far end of the room and push water toward the shower drain. You can also use a hand-held shower head as a hose.  

Walls in regular bathrooms can be difficult to clean, especially when they’re made of drywall or plaster. Wet room walls are hardscaped and water-sealed. So, you can clean them with soap and water without fear of damage.
