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 busy Carmarthen household sharing one main bathroom, a thermostatic shower over a full-size bath is usually the most practical layout. If your Carmarthen home has just one bathroom, we plan the fit so the toilet is working again at the end of each day wherever the job allows.
Supplies across most of Dyfed are soft. 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
- Final silicone, a test of every tap and waste, and a clean handover
- New pipework, wastes and isolation valves, plus a thermostatic shower valve so the temperature holds when someone runs a tap
- A free home survey covering room sizes, the soil stack position, your boiler or cylinder type and water pressure
- A layout that keeps a full-size bath, with options for a shower over it or a separate enclosure if the room allows
Decisions to make first
Bath material
Reinforced acrylic is warm to the touch and light on the floor. Steel enamel is harder-wearing and feels more solid, but it draws heat from the water faster.
Screen or curtain
Glass keeps water in better than a curtain and does not go mouldy at the hem. A folding or hinged screen swings out of the way when you are kneeling to bath a child.
Rules that apply in Wales
Wales has its own Part P, with a wider list of notifiable electrical work than England, and its own Part F with similar extract rates if the fan is replaced. Ask your electrician which parts of the job will be notified, and expect a certificate at the end.
