Working in East Grinstead
We cover every part of East Grinstead, including RH19, and nearby Horley (7.5 miles) and Crawley (7.7 miles).
In East Grinstead, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your East Grinstead home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. We quote new en-suites in East Grinstead only after checking the drainage route on site, so the price reflects the work your house actually needs.
Supplies across most of West Sussex are hard. If your supply in East Grinstead 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 door that suits a tight space: inward, outward, sliding or a pocket door
- 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 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.
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.
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.
