The Pros and Cons of Wet Room Bathrooms

I often get asked about wet rooms more than almost any other bathroom feature, and for a good reason. It's a design which allows you to walk straight into the shower with no curb and no glass to hold the spray in. It's become rather popular, but it's not the right choice for every house. I'm Peter Kravchuk, and this guide covers what a wet room actually involves so you can decide if it's right for your home.

What Is a Wet Room Bathroom?

It is a completely waterproof bathroom with no raised threshold or shower tray. The floor slopes slightly to allow water to drain through one point to a drain located in the lowest part of the bathroom. A continuous waterproofing system installed over the floor substrate and throughout the wet area protects the structure below and behind the tile. To say there are no partitions at all would be incorrect. A number of rooms that we design in Washington still use a glass barrier for a separate cubicle for showers and bathtubs, separating the area with a sheet of glass from the toilet and the sink.

How a Wet Room Differs From a Conventional Bathroom

A traditional bathroom design keeps water contained with a shower pan and maybe a glass door. A wet room gets treated as a wet space, as there's no pan and curb. That doesn't only change the feel when you walk in. The floor has to slope toward the drain across its entire surface, which often means adjusting the subfloor framing along with the finish layer. Cement board, tile, and grout are not a substitute for waterproofing. Wet-zone walls and the shower floor need an approved waterproofing system behind or directly beneath the tile assembly. And, since there's no enclosure holding steam in one spot, ventilation has to work harder. All of that shows up on the invoice. In case of a regular remodel, we retile around an existing shower pan and call it done. In a wet room, we're waterproofing the required areas, creating the proper drainage slope, and making sure the bathroom ventilation meets the needs of the space and applicable code requirements.

Pros of a Wet Room

Step-free access is a no-brainer for anyone with mobility concerns, since you can walk, roll, or shuffle across the entire floor without obstruction. Cleaning is easier too, as you don't have to squeegee shower doors or clean the caulk joint between the door and the tiles. Done right, a wet room can make a small bathroom feel bigger. We get that by eliminating the shower enclosure, which is usually what makes a small room feel boxed in. Large-format tile from floor to ceiling adds to the spa-style impression and tends to last longer than glass shower screens. There's also less to maintain long-term, e.g., no shower tray to regrout or no panel hardware to replace.

Benefit

A wet room only works if the waterproofing is done right the first time, and there's very little room for error. By that I mean a fully sealed membrane system under the tile, correctly detailed at every seam and transition where the floor meets the wall or the drain. Miss one spot and water will go into the subfloor. Because it's hidden under finished tile, you usually don't know until there's a smell or stain on the ceiling below, turning it from a patch job into a "tear it out" show. This is exactly why I don't let inexperienced crews near a wet room membrane installation. Good ventilation is essential. Without it, steam will spread throughout the room, increasing the potential for mold to build up if the exhaust fan isn't doing its job. A wet room lets everything get wet, and that changes a few practical things. Towels and toiletries need a home outside the splash zone, so plan a wall niche or shelf that isn't in the direct spray path. The floor needs to be genuinely slip-resistant tile, especially with kids or older family members in the house. If someone has balance issues, they shouldn't be reaching for the edge of a fold-down seat to steady themselves (it can shift or fold under real weight). What actually helps is a grab bar, made of solid stainless steel or a similarly rated material and mounted into blocking we install behind the tile. Even when a client doesn't want a visible grab bar on day one, I always recommend we put blocking in during the rough-in anyway. It costs almost nothing while the wall is open, and it means a real grab bar can be installed later at the right height without cutting into finished tile. Providing accessibility like this is a genuine part of what my team does on every bathroom remodel. Resale is a real concern here, since some buyers love wet rooms while others won't purchase without a tub, so the impact cuts both ways.

Drawback

Costs depend on scope and location, so take any number you see online with a grain of salt. As of 2026, professional wet room installs go for $6k to $20k nationally, averaging around $13k per Angi's data (luxury builds hit $35k on higher-end tile and fixtures). Greater Seattle is generally a higher-cost remodeling market, so local wet room projects may come in above national averages depending on the size, waterproofing scope, plumbing changes, tile, fixtures, and structural work involved.

Planning a Wet Room

This level of detail is exactly why I tell clients to treat a wet room as part of a full renovation. If you're already opening the walls and floor, all of the following is worth planning for properly. Open bathroom layouts put more pressure on water management, steam, and comfort than a standard tub-shower does. The floor should slope gently to a central or linear drain so water doesn't puddle near the vanity. A linear drain doesn't have more capacity than a round one just because of its shape. Drainage capacity comes down to outlet size, the open area of the grate, the trap and waste line behind it, and how much water your shower outlets are putting out. Washington's plumbing code generally requires at least a 2-inch shower waste outlet, with a narrow exception for 1.5-inch outlets on existing tub-to-shower conversions, and only with AHJ approval and a single showerhead rated at 1.8 gpm or less. What a linear drain gets you is one plane slope, and that's what makes it easier to run large-format tile and land a clean, curbless transition. High-capacity exhaust fans clear steam fast, which matters even more without an enclosure holding it in one place. If you are already down to the studs, then this is the time to add underfloor heating as well. Once the floor is sealed back up, retrofitting heat means ripping it all back out.

Is a Wet Room Right for Your Bathroom?

I get this question a lot, and all I can say is it depends on more than just wanting the look. A wet room makes sense when accessibility is a real priority. If you've got an aging parent moving in, or you're planning to age in place yourself, step-free access removes the curb as a trip hazard and can make the bathroom easier to use for someone with limited mobility. Here's where I'd tell a client to think twice. If your bathroom is already tight, a wet room needs enough square footage to keep the dry zone, vanity, and toilet dry, or it starts to feel like you're living inside a shower. Some homeowners also find an open wet room feels colder without an enclosure holding in steam and warmth, which matters more here in a Pacific Northwest winter. Cleaning is a toss-up. Some people think the whole surface is easier to squeegee down. Others find that without a contained shower, water and soap scum spread further. And if you're planning to sell within the next few years, know your buyer pool. In some markets a wet room is considered a premium spa feature. In others, buyers specifically want a tub and see a wet room as a downgrade. There's one more thing I always flag. The room stays wet for a while after someone showers, and if it's your only bathroom, whoever needs to brush their teeth next is doing it around a damp floor and a soggy roll of toilet paper if the storage wasn't properly planned. If your house is older, like a lot of the homes my team and I work on, nothing is quite plumb or level anymore, and that makes it harder to seal the room properly and get the venting right. Here's my rule of thumb. If you're doing a full renovation, and access or a small footprint is the driving factor, a wet room is usually worth it. If it's a quick refresh or you're not sure your buyer pool wants it, a well-built shower with a low curb and a cubicle will do.

How We Created a Safer, Curbless Bathroom in Sultan, WA

I like talking about wet rooms in terms of function and aesthetics, because that's what most of my clients care about. A good example of what I mean is a project we did in Sultan, WA. A small fire had damaged the family's home, an older property. Once we were in there for the full gut remodel, the owner told us what mattered to them, which was wheelchair access and long-term mobility for a family member. That became the whole focus of the bathroom. We understand how much that kind of change affects daily life, so we built the bathroom around it from the start. This wasn't a wet room, to be clear, but the planning principles behind it are close to identical to what goes into a full wet room design. We thought through where the water needed to go, how the floor needed to slope, what the waterproofing had to handle, and how to get a stepless transition without a curb. We brought every system in that bathroom up to current code, including all new wiring, and replaced the old tub with a curbless, wheelchair-accessible shower built the same way I'd build a wet room shower zone. That's why I always recommend treating wet room planning as part of a full renovation. The project ran on a $307K budget and wrapped in three months, on schedule.

FAQ

What are the disadvantages of a wet room bathroom?

Waterproofing tops the list. Skimp on the membrane, and water damage to the subfloor can follow. Poor airflow traps moisture and can lead to mold and dampness. Beyond that, storage gets trickier since towels and toiletries need to live outside the splash zone, the whole room needs genuinely slip-resistant tile, and resale can go either way depending on your buyer pool.

Can a Toilet Be Installed in a Wet Room?

Yes, as long as it sits outside the direct spray path and the surrounding walls and floor carry the same waterproofing as the shower.

What Are The Main Benefits Of Having A Wet Room?

Step-free access is the one that matters for anyone managing mobility issues or for a household with both young kids and an aging parent. Aside from that, a wet room is easy to clean with fewer nooks and crannies, makes smaller bathrooms feel bigger, and gives the room a sleek, spa-like look that holds up well over time.

Are Wet Rooms a Modern Bathroom Trend or Are They Outdated?

They've been standard in Europe for decades and have grown steadily more popular in the U.S. since around 2020.

Are Wet Rooms a Good Option for Small Bathrooms?

Yes. Dropping the shower enclosure and tray often makes a compact bathroom feel larger, since there's no glass or framing breaking up the room.

What Type Of Tile Is Best For A Wet Room?

Porcelain or natural stone tile with a textured, slip-resistant finish can work well in a wet room. Large-format tile reduces the number of grout joints, but waterproofing comes from the membrane system underneath, not from the tile or grout. With a point drain, smaller tiles are often easier to slope properly, while linear drains can work well with larger-format tile.

Do Wet Rooms Increase Property Value?

It depends more on the buyer pool. Some buyers see a wet room as a premium, spa-like upgrade, especially in a primary bathroom. Others expect at least one traditional shower or tub somewhere in the home, so converting your only full bathroom can narrow the resale chances.

How Much Does a Wet Room Cost on Average?

As of 2026, professional wet room installations typically range from $6,000 to $20,000 nationally. Greater Seattle projects may cost more depending on the waterproofing scope, plumbing changes, tile, fixtures, and structural work involved.
