Working in Cardiff
We cover every part of Cardiff, including CF10, CF11 and CF24, and nearby Penarth (2.9 miles) and Caerphilly (6.7 miles).
Cardiff is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. If your Cardiff home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. For an en-suite in Cardiff, the first question at the survey is always where the waste can reach the soil stack.
Most of South Glamorgan has moderately hard water. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Cardiff. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
Decisions to make first
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.
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
Rules that apply in Wales
Wales has its own Part F with similar extract rates and its own Part P, which makes more electrical work notifiable than in England. The drainage for a new en-suite falls under Part H. The work should be notified, and you should receive the certificates at the end.
