Working in Daventry
In Daventry we cover NN11; we also cover Rugby, 9 miles away, and Northampton.
Homes in and around Daventry vary, so we look at the floor, the walls and the water system before we price anything. We quote new en-suites in Daventry only after checking the drainage route on site, so the price reflects the work your house actually needs. For an en-suite in Daventry, the first question at the survey is always where the waste can reach the soil stack.
Most of Northamptonshire has hard water. If your supply in Daventry 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 pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- 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
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.
