Working in Aberdare
We cover every part of Aberdare, including CF44, and nearby Rhondda (3.8 miles) and Merthyr Tydfil (3.8 miles).
In Aberdare, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. For a loft bathroom in a tank-fed Aberdare home, we work out how the shower will get its pressure before choosing a single fitting. We plan loft bathrooms in Aberdare around the roof line, so the shower sits where you can stand and the eaves become storage.
Most of Mid Glamorgan is supplied with soft water. If that holds for your street in Aberdare, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- 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
- 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
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.
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.
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.
