Working in Cowley
In Cowley we cover OX1, OX3 and OX4; we also cover Oxford, 2.5 miles away, and Abingdon.
Cowley gets the same process as anywhere else: a free survey at your home and a written, itemised quote. We plan loft bathrooms in Cowley around the roof line, so the shower sits where you can stand and the eaves become storage. If your Cowley home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Water across much of Oxfordshire is 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
- An extractor fan ducted through the roof or a gable wall, with the duct insulated through cold spaces
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A survey of the headroom across the room, with the usable height marked at each fitting position
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
Decisions to make first
Bath or no bath
A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.
Eaves storage
Low cupboards built into the slope behind the WC or basin take clutter out of the room and hide the pipework.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
