Working in Carmarthen
As well as Carmarthen itself (SA31), we survey in Llanelli, Ammanford and Gorseinon.
Being a smaller town does not change how we work in Carmarthen: free survey, written quote, one team. If you are planning a wet room in Carmarthen for level access, we design the fall and drain so the floor is flush from the doorway. If your Carmarthen home has a concrete ground floor, a downstairs wet room may need the screed cut out to set the drain.
Supplies across most of Dyfed are soft. If that holds for your street in Carmarthen, 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 thermostatic shower valve, exposed or concealed, with heads to suit your water system
- A frameless glass screen fixed to the wall and floor
- Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection
- A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
Decisions to make first
Open or screened
A fully open shower with no glass only works in a larger room, with the basin, WC and towels well away from the spray.
Underfloor heating
Electric underfloor heating under the tiles dries the floor quickly after a shower; it is typically £700 to £1,500 for a bathroom.
Rules that apply in Wales
In Wales, Part H covers new drainage and the Welsh Part F sets similar extract rates. The Welsh Part P makes more electrical work notifiable than in England, so the electrician should notify and certify the work.
