Working in Caterham
In Caterham we cover CR3, CR6 and RH9; we also cover Coulsdon, 3.7 miles away, and Purley.
Caterham gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For an en-suite in Caterham, the first question at the survey is always where the waste can reach the soil stack. If your Caterham en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Most of Surrey has hard water. If your supply in Caterham 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.
What the job includes
- 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
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
Decisions to make first
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
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.
