Working in Caernarfon
As well as Caernarfon itself (LL55), we survey in Bangor, Holyhead and Llandudno.
Being a smaller town does not change how we work in Caernarfon: free survey, written quote, one team. We survey cloakrooms in Caernarfon with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. If your Caernarfon cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Most of Gwynedd is supplied with soft water. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Splashback or feature tiling and a new floor, often LVT or porcelain
- 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
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
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.
