Working in Darlington
As well as Darlington itself (DL1, DL2 and DL3), we survey in Newton Aycliffe, Yarm and Stockton-on-Tees.
Across a large town like Darlington, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. If you live in a Darlington flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. If your Darlington home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue.
Supplies across most of County Durham are moderately hard. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Darlington. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
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.
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.
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.
