Working in Cowley
We work right across Cowley — OX1, OX3 and OX4 — and in neighbouring Oxford and Abingdon.
Being a smaller town does not change how we work in Cowley: free survey, written quote, one team. If your Cowley home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. If you live in a Cowley flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Supplies across most of Oxfordshire are hard. If your supply in Cowley 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 shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- 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
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
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.
