An en-suite is a small room with a big job. It takes the pressure off the main bathroom, and it adds real appeal to a house when you come to sell. Because it sits right next to a bedroom, it also has to be quiet, well ventilated and leak-free, or the problems show up in the bedroom first: damp patches on the wall, a fan humming at night, a stain on the ceiling below.
We do two kinds of en-suite work. Refits replace the shower, basin and WC in an existing en-suite, usually in four to eight working days. New en-suites are formed inside a bedroom or box room, which means stud walls, a route for the waste to reach the soil stack, an extractor fan ducted outside and electrics to regulations. We check whether that drainage route exists at the survey, before you spend anything.
What does an en-suite with us include?
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A door that suits a tight space: inward, outward, sliding or a pocket door
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- Tiling, silicone, testing and making good on the bedroom side of any new walls

What do you need to decide?
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
Door type
An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
Noise
Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
