Working in Llanelli
We work right across Llanelli — SA15 — and in neighbouring Gorseinon and Swansea.
Homes in and around Llanelli vary, so we look at the floor, the walls and the water system before we price anything. We survey cloakrooms in Llanelli with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. For a new cloakroom in Llanelli, the first thing we look at is where the nearest drain or soil stack runs.
Water across much of Dyfed is soft. 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
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A concealed cistern frame or WC unit where the space allows
Decisions to make first
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
Finishes
A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.
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.
