Working in West Molesey
In West Molesey we cover KT8, KT12 and KT13; we also cover East Molesey, 1.3 miles away, and Sunbury-on-Thames.
West Molesey gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We quote new en-suites in West Molesey only after checking the drainage route on site, so the price reflects the work your house actually needs. If you live in a West Molesey flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Water across much of Surrey is hard. If your supply in West Molesey 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 shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- 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
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
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.
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.
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.
