Working in Cwmbran
In Cwmbran we cover NP44; we also cover Pontypool, 3.4 miles away, and Risca.
Homes in and around Cwmbran vary, so we look at the floor, the walls and the water system before we price anything. For a loft bathroom in a tank-fed Cwmbran home, we work out how the shower will get its pressure before choosing a single fitting. If your Cwmbran home has a gravity-drained WC on another floor, a macerator in the loft may open up more layout options.
Hardness differs from one part of Gwent to the next. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Cwmbran. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- A check of the floor joists where a bath or large shower tray will sit
- A drainage route from the loft to the soil stack with enough fall, or a pumped waste or macerator where the rules allow it
Decisions to make first
Gravity or pumped waste
Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.
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.
Rules that apply in Wales
Wales applies its own Part P, with a wider notifiable list than England, and its own Part F with similar extract rates. Part H covers the new drainage route down from the loft.
