Supplies across most of Kent are very hard. If your supply in Maidstone is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier. If your Maidstone en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
What the job includes
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- 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
Decisions to make first
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.
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.
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.
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.
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.
