Working in Hatfield
As well as Hatfield itself (AL9 and AL10), we survey in Welwyn Garden City, St Albans and Potters Bar.
In Hatfield, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Hatfield home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options. We plan loft bathrooms in Hatfield around the roof line, so the shower sits where you can stand and the eaves become storage.
Supplies across most of Hertfordshire are very hard. If your supply in Hatfield 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 drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
- A check of the floor joists where a bath or large shower tray will sit
- A survey of the headroom across the room, with the usable height marked at each fitting position
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
Decisions to make first
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
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.
