We see more failed wet rooms than failed shower enclosures, and it's almost never the concept that's at fault — it's corners cut in the waterproofing underneath a finish that looks identical either way once tiled.
What actually separates a wet room from an enclosure
A shower enclosure contains water within a glazed cubicle and a tray, so waterproofing only needs to be reliable within a small, well-defined footprint.
A wet room removes that containment and relies on tanking the entire floor and the lower section of every wall in the room, with the floor falling evenly toward a linear or point drain. There is no tray to catch a waterproofing mistake — the whole room is the tray.
The failure mode to understand before committing
If the tanking membrane isn't continuous, isn't properly lapped at joints and upstands, or the floor falls aren't accurate enough to drain fully, water sits or migrates under the tiles and eventually finds its way through the ceiling below.
Because this failure is invisible until it shows as a stain on a ceiling, sometimes months later, a wet room is not somewhere to accept a cheap quote — the labour and materials for correct tanking are where the cost genuinely needs to go.
Where each one suits the room
In a small bathroom, a wet room removes the visual bulk of a tray and glass screen and makes the whole floor read as one space, which is often the difference between a bathroom feeling cramped and feeling generous.
A shower enclosure is simpler to install, contains water more predictably because the containment is built into a manufactured tray and screen, and doesn't require tanking the whole room — a real advantage if the floor structure below isn't suited to a full wet room build-up.
Living with each one over ten years
A well-tanked wet room, once installed, needs very little beyond keeping the drain clear and resealing silicone at wall junctions periodically — there's no tray seal, no shower door track and no glass to keep clean of limescale.
A shower enclosure has more components that age: door seals harden and need replacing, hinges can start to sag on heavier glass doors, and the tray-to-wall silicone joint needs regular attention, since that joint is doing the job the wet room's tanking does invisibly underneath.
What this does to resale appeal
A properly built wet room is an attractive, spacious-feeling upgrade to most buyers, but a visibly amateur one — uneven falls, ponding water, a floor that looks damp days after use — raises exactly the doubts a survey report will later confirm.
A shower enclosure is the safer, more universally understood choice if you expect to sell within a few years, simply because its containment is visible and self-explanatory in a way that tanking quality never is to a viewer.
Common questions
Can any bathroom be converted into a wet room?+
Most can, but floor build-up and joist depth need checking first, since a wet room floor often needs to drop slightly to achieve the fall to the drain, which isn't always possible over a timber floor without altering the structure.
Is a wet room more expensive than a shower enclosure?+
The wet room build-up, with full tanking and floor falls, generally involves more labour than fitting a manufactured tray and enclosure, so expect it to cost more for a comparable size — the trade-off is a different look and feel, not a cheaper one.
How do I know if a wet room has been tanked properly?+
You largely can't tell by eye once it's tiled — this is a question to ask the installer directly about the tanking system used, and to see evidence of on a written specification, before work starts rather than after.
Get your wet room specified and quoted properly
We'll tell you honestly whether your floor structure suits a wet room, and provide full tanking as standard, not as an upgrade.
