Working in Ewell
We cover every part of Ewell, including KT4, KT17 and KT19, and nearby Epsom (1.6 miles) and Sutton (2.1 miles).
In Ewell, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If the en-suite in your Ewell home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If you live in a Ewell flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Most of Surrey has hard water. If your supply in Ewell 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
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- 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
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.
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.
