If you are renovating a bathroom and want to ditch the bath, the two most popular options are a wet room and a walk-in shower. They look similar at first glance, both give you an open, modern showering space, but they are built very differently and suit different situations.
This guide explains the real differences between a wet room and a walk-in shower so you can choose the right one for your bathroom, your home, and how you actually use the space.
What Is a Wet Room?
A wet room is a fully waterproofed bathroom where the entire floor (and often the walls) are tanked with a waterproof membrane. The shower area is open, with no tray and no enclosure. Water drains through a floor-level drain, and the floor is graded to direct water toward it.
In a true wet room, you could point the showerhead at any surface in the room and the water would drain safely without reaching the structure of the building. The whole room is the shower.
Our wet room installation service covers the full process from floor preparation and tanking through to tiling and drainage.
What Is a Walk-In Shower?
A walk-in shower is an open-entry shower enclosure, usually with a glass screen on one or two sides, a shower tray at the base, and standard bathroom walls and flooring surrounding it. The tray collects the water and directs it to a waste outlet.
Walk-in showers feel open and spacious compared to a traditional cubicle, but the waterproofing is contained within the tray and the tiled area immediately around the shower. The rest of the bathroom floor and walls are finished as a standard bathroom.
The Key Differences
Both options remove the bath, both create an open showering space, and both look modern. But the construction method, waterproofing scope, and practical implications are quite different.
Waterproofing
This is the fundamental difference between the two.
A wet room requires full tanking of the floor and walls. A liquid-applied or sheet membrane is applied across every surface that might come into contact with water. The floor is graded to fall toward the drain. This is specialist work that must be done correctly because any failure in the membrane can cause water to reach the subfloor and structural timbers.
A walk-in shower relies on the shower tray itself for waterproofing. The tray sits on the floor and contains the water within its raised edges. The wall area behind and around the showerhead is tiled and sealed, but the waterproofing does not extend across the whole room. This is a simpler installation with less structural risk if anything goes wrong.
Floor Construction
In a wet room, the floor must be prepared to create a gradient toward the drain. This often involves building up the floor with a screed or using a pre-formed wet room former (a sloped tray that sits under the tiles). The finished floor is tiled and appears seamless with no visible tray edge.
In a walk-in shower, the tray sits on top of the existing floor. Low-profile trays are only 25mm to 40mm high, so the step-up is minimal, but there is still a visible edge between the tray and the bathroom floor. Some homeowners prefer this because it clearly defines the shower zone.
Installation Complexity
Wet rooms are more complex to install. The tanking, floor gradient, and drain positioning all require experience and precision. A mistake in the membrane application or the floor fall can cause drainage problems or, worse, water damage that is invisible until it has already caused structural harm.
Walk-in showers are more straightforward. Fitting a tray, connecting the waste, tiling the walls, and installing a glass screen is well within the scope of any competent bathroom fitter. The waterproofing is simpler because the tray does the heavy lifting.
Appearance
Wet rooms generally create a cleaner, more seamless look. Because there is no tray edge, the floor tiles flow continuously from the bathroom floor into the shower area. This creates a sense of space that works particularly well in smaller bathrooms.
Walk-in showers still look modern and open, but the tray creates a visual boundary. For some homeowners, this is actually a positive because it clearly separates the wet and dry zones of the bathroom.
Accessibility
Wet rooms are the better option for accessibility. A true wet room has a completely level floor with no step, no tray to climb over, and no enclosure to navigate around. This makes it ideal for wheelchair users, older residents, or anyone with reduced mobility. Grab rails, fold-down seating, and non-slip tiles can be integrated into the design.
Walk-in showers are more accessible than a traditional bath or enclosed shower cubicle, but most still have a small lip where the tray meets the floor. Low-profile trays reduce this to 25mm or so, but it is not truly level-access. If accessibility is a primary concern, a wet room is the stronger choice.
Maintenance
Walk-in showers are generally easier to maintain. The tray is a single moulded surface with no grout lines, making it quick to clean. The glass screen wipes down easily.
Wet rooms have more grout lines on the floor, which can accumulate soap residue and require regular cleaning. The drain also needs periodic clearing to prevent blockages. That said, modern anti-bacterial grouts and linear drains have made wet room maintenance much simpler than it used to be.
Drainage
Walk-in showers drain into a standard waste trap through the tray. As long as the waste is connected properly and the tray is level, drainage is reliable and consistent.
Wet rooms rely on the floor gradient to direct water to the drain. If the gradient is too shallow, water pools on the floor. If it is uneven, water collects in low spots rather than flowing to the drain. This is why the floor preparation stage is so critical in a wet room installation, and why it should be done by someone with specific experience.
When a Wet Room Is the Better Choice
A wet room makes the most sense when:
- Accessibility is important. Level-access entry is the safest and most practical option for anyone with mobility issues.
- The bathroom is small. Removing the tray edge and creating a seamless floor makes a compact bathroom feel significantly larger.
- You want a premium, minimal look. Wet rooms have a clean, hotel-like aesthetic that works well in modern homes.
- You are doing a full bathroom renovation anyway. If you are stripping the room back to the walls and floor, the additional work for tanking and grading is a relatively small step up.
- The bathroom is part of a larger property renovation. When the floor is being rebuilt anyway, incorporating a wet room adds value without major additional disruption.
When a Walk-In Shower Is the Better Choice
A walk-in shower makes more sense when:
- You want a simpler installation. Less structural work, less specialist waterproofing, and a faster installation timeline.
- The existing floor structure is not ideal for a wet room. Timber-framed upper floors can be adapted for wet rooms, but it adds complexity and cost. A walk-in shower with a tray avoids that entirely.
- You prefer defined wet and dry zones. Some homeowners prefer knowing that the shower water is contained within the tray area, especially in a family bathroom where young children are using the space.
- Budget is a priority. Walk-in showers are less expensive to install because the waterproofing is simpler and the floor preparation is minimal.
- You are replacing a bath but keeping the rest of the bathroom largely as-is. If the bathroom does not need a full strip-out, fitting a walk-in shower tray is less disruptive than converting the entire floor to a wet room.
Can You Have a Partial Wet Room?
Yes. A partial wet room is a middle-ground option where the shower area is tanked and graded with a floor-level drain, but the rest of the bathroom floor and walls are finished as standard. A glass screen or low wall separates the wet area from the rest of the room.
This gives you the level-access, seamless shower zone of a wet room without the cost and complexity of tanking the entire room. It is a popular option for en-suites and smaller bathrooms where a full wet room is not necessary but a shower tray feels too conventional.
Flooring Considerations
Your choice between a wet room and a walk-in shower affects the rest of the bathroom floor.
In a wet room, the floor tiles must be suitable for constant water contact. Porcelain tiles with an anti-slip rating of R10 or higher are the standard recommendation. Natural stone can work but needs sealing and ongoing maintenance. The tiles in the shower zone are often smaller (mosaic-format) to follow the floor gradient smoothly, while wall tiles and surrounding floor areas can use larger formats.
With a walk-in shower, the bathroom floor outside the tray can be any suitable material, including vinyl, laminate, or porcelain. The floor does not need to handle standing water because the tray contains it. Our flooring service can help you choose the right material for your bathroom floor.
What About Resale Value?
Both options add value to a property compared to an ageing bath or enclosed shower cubicle. Walk-in showers are widely understood and appeal to a broad range of buyers. Wet rooms are increasingly desirable, particularly in modern builds and premium refurbishments, but some buyers with young children prefer a bathroom that still has a tray or a bath.
If resale value is a consideration, the safest approach is to have at least one bathroom in the house with a bath (for families) and use a wet room or walk-in shower in the en-suite or secondary bathroom.
Frequently Asked Questions
Is a wet room just a shower without a tray? Not quite. A wet room is a fully waterproofed room where the entire floor and walls are tanked with a membrane. Simply removing a shower tray without proper tanking and floor grading is not a wet room and will likely cause water damage. The waterproofing is what makes it a wet room, not just the absence of a tray.
Can I convert my existing bathroom into a wet room? In most cases, yes. The floor structure needs to be assessed to confirm it can support the grading and tanking work. Concrete ground floors are straightforward. Timber upper floors can be adapted but require additional preparation to ensure the floor is rigid enough. We assess this during the initial visit.
Do wet rooms make the whole bathroom wet? A properly graded wet room directs water toward the drain efficiently. You will get some splash outside the immediate shower area, but a glass screen helps contain most of it. The rest of the room dries quickly because the floor is tiled and waterproof. It is not as dramatic as some people imagine.
Which is better for a small bathroom? A wet room usually works better in a small bathroom because there is no tray edge eating into the floor space. The seamless floor creates an unbroken visual line that makes the room feel larger. For a detailed look at the full process, see our bathroom renovation cost guide.
Can a walk-in shower be made fully accessible? A low-profile tray reduces the step to 25mm or less, which is manageable for many people. But for true level-access, a wet room with no step at all is the better option. If the bathroom is being adapted for a wheelchair user or someone with significant mobility challenges, we would always recommend a wet room.
What if my bathroom project is part of a larger renovation? If you are renovating multiple rooms at the same time, it often makes sense to have the bathroom work coordinated alongside everything else. Our property renovation service manages all trades under one project, so your bathroom, kitchen, flooring, and decoration all happen on one schedule. See our home renovation guide for more on planning multi-room projects.
