Working in Carmarthen
In Carmarthen we cover SA31; we also cover Llanelli, 13.5 miles away, and Ammanford.
Carmarthen gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For shower rooms in Carmarthen, we check the water pressure and hot-water system at the survey, because that decides how well the shower will perform. Where a Carmarthen shower room doubles as the guest bathroom, we plan storage so it stays clear of clutter.
Water across much of Dyfed is 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
- Extractor fan, lighting and towel rail wired by a qualified electrician, tested and certified
- A basin and WC to suit the space, freestanding or set into a fitted furniture run
- Recessed niches or shelving in the shower wall
- Tanking to the shower area, then wall and floor tiling
Decisions to make first
Storage
With no bath, there is often space for a full-width vanity unit or a tall cupboard for towels.
Drain
A centre waste in a tray is the norm. A linear drain along one wall lets a tiled floor fall one way, so large tiles can run through.
Rules that apply in Wales
Wales has its own Part P and Part F. More electrical work is notifiable there than in England, and the extract rates are similar.
