The short answer
The core difference is waterproofing and level. A wet room is a fully tanked, open space where the shower area is level with the rest of the floor and water drains through a built-in floor gully — no tray and no step. A shower room keeps a low-profile tray and glass enclosure, so the water stays contained in one corner and only that zone needs tanking. A wet room typically costs more — often £5,000–£10,000 against roughly £800–£2,500 for a good walk-in enclosure with a tray — because the whole floor and lower walls are waterproofed and tiled to a fall. A wet room feels more open and is easy to clean, but without at least a glass screen the spray reaches more of the room. The right answer depends on space, budget and how you want the room to feel.
This is really a trade-off between an open, fully tanked floor and a contained, lower-cost enclosure. Here is how the two compare on the things that matter.

How they compare
A wet room waterproofs the entire floor and lower walls and falls them to a gully, giving a seamless, open space with nothing to step over — but it needs careful tanking and usually a glass screen to keep spray off the far side of the room. A shower room uses a low tray and enclosure, so only that zone is tanked and the rest of the room stays dry; it costs less and contains heat and steam, but it keeps a step and a tray edge. Many homeowners fit a partial glass screen in a wet room to get most of the open feel while keeping the rest of the floor drier.

How to choose for your home
- Want an open, seamless look or level access? a wet room delivers it, ideally with a glass screen to manage spray.
- Tighter budget or want water firmly contained? a walk-in enclosure with a low-profile tray gives much of the look for less.
- Small room? a wet room can make it feel larger, but plan ventilation and a screen carefully (see the small wet room page).
- Only bathroom in the house? think about resale — some buyers still want a bath somewhere in the home.

Frequently asked questions
What is the difference between a wet room and a shower room?
A wet room is fully tanked with a level floor and a built-in drain gully, so there is no tray or step. A shower room keeps a low tray and glass enclosure, so only that zone is waterproofed and the water stays contained in one corner.
Is a wet room more expensive than a shower room?
Usually yes. A fully tanked wet room often costs £5,000–£10,000 because the whole floor and lower walls are waterproofed and tiled to a fall, whereas a good walk-in enclosure with a tray is often £800–£2,500 installed.
Can a wet room work in a small bathroom?
Yes — a level, open floor can make a small room feel larger. Plan a glass screen and good ventilation so the spray and damp are controlled; see the small wet room page for the detail.
