Most of Merseyside is supplied with soft water. If that holds for your street in Liverpool, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier. If you live in a Liverpool flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
What the job includes
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A door that suits a tight space: inward, outward, sliding or a pocket door
Decisions to make first
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.
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.
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.
Rules that apply in England
Forming an en-suite inside an existing bedroom does not normally need planning permission, but it is usually building-regulations work because it adds drainage, ventilation and electrics. All wiring must meet BS 7671, with 30 mA RCD protection on every circuit in the room. A macerator or pumped WC is acceptable only where the home also has a WC on gravity drainage. In a listed building, a new soil or vent pipe through a wall needs listed building consent.
In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.
