Working in Swanley
We cover every part of Swanley, including BR8, and nearby Bexley (3.2 miles) and Dartford (3.8 miles).
Being a smaller town does not change how we work in Swanley: free survey, written quote, one team. For an en-suite in Swanley, the first question at the survey is always where the waste can reach the soil stack. If the en-suite in your Swanley home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Most of Kent has very hard water. If your supply in Swanley 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- 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 door that suits a tight space: inward, outward, sliding or a pocket door
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.
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
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.
