Working in Egham
In Egham we cover TW20; we also cover Staines, 2 miles away, and Chertsey.
In Egham, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We quote new en-suites in Egham only after checking the drainage route on site, so the price reflects the work your house actually needs. If the en-suite in your Egham home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Most of Surrey has hard water. If your supply in Egham 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
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- 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
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.
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.
