Working in Cardiff
As well as Cardiff itself (CF10, CF11 and CF24), we survey in Penarth, Caerphilly and Barry.
In a city the size of Cardiff, parking and access for a skip are worth sorting before the start date — we will ask at the survey. For a new cloakroom in Cardiff, the first thing we look at is where the nearest drain or soil stack runs. If you are refreshing a dated cloakroom in Cardiff, a wall-hung WC and slim vanity can change the room in a few days.
Most of South Glamorgan has moderately hard water. Taps and wastes will need an occasional descale, and chrome or brushed finishes are easier to keep clean than polished brass. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- Lighting wired by a qualified electrician, tested and certified
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
Decisions to make first
WC style
A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.
Basin
A corner basin fits the tightest rooms. A slim vanity basin with a cupboard underneath gives somewhere to keep spare toilet rolls and soap, and hides the trap.
Rules that apply in Wales
In Wales, Part H covers a new drainage connection and the Welsh Part F covers ventilation, with rates similar to England. The Welsh Part P has a wider notifiable list, so check with your electrician whether the cloakroom lighting and fan need to be notified.
