Working in Carmarthen
As well as Carmarthen itself (SA31), we survey in Llanelli, Ammanford and Gorseinon.
Carmarthen gets the same process as anywhere else: a free survey at your home and a written, itemised quote. For a period house in Carmarthen with high ceilings, we plan the lighting and tile heights to suit the proportions of the room. If you live in a listed building in Carmarthen, we flag any change that may need listed building consent, such as a new soil pipe through a wall.
Most of Dyfed is supplied with soft water. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Floor strengthening where a stone-resin, cast-iron or natural stone bath needs it
- Large-format porcelain, natural stone or microcement over full tanking
- Layout drawings, wall elevations and a tile setting-out plan
- Underfloor heating, layered lighting and any steam unit wired by a qualified electrician, tested and certified
Decisions to make first
Lighting
Layer it: IP-rated ceiling lights for general use, a lit mirror at the basin and low-level LED in niches or plinths for night, each on its own switch or dimmer.
Heating
Underfloor heating under stone or porcelain makes the room comfortable all year; pair it with a towel rail for drying.
Rules that apply in Wales
Wales has its own Part P with a wider notifiable list than England, so the new electrical work should be notified and certified. An unvented cylinder still needs a G3-qualified installer, and boiler work a Gas Safe registered engineer.
