Which towns do we cover in Gwynedd?
Water across much of Gwynedd is 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. If your Bangor 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.
What the job includes
- A layout that keeps a full-size bath, with options for a shower over it or a separate enclosure if the room allows
- A free home survey covering room sizes, the soil stack position, your boiler or cylinder type and water pressure
- Moisture-resistant boarding and tanking around the bath and shower before any tiling
- New pipework, wastes and isolation valves, plus a thermostatic shower valve so the temperature holds when someone runs a tap
- Final silicone, a test of every tap and waste, and a clean handover
- Supply of the bath, basin, WC, brassware, shower, screen, tiles and heated towel rail
Decisions to make first
Storage
A vanity under the basin, a tall unit or a mirror cabinet. High-level or lockable storage keeps medicines and cleaning products out of reach of small children.
Bath shape
A standard 1700 mm bath fits most rooms. A shower bath widens at one end to give more standing room under the shower; a double-ended bath puts the waste in the middle so two children can share without one sitting on the plug.
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.
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.
Rules that apply in Wales
Refitting a family bathroom in the same room does not need planning permission. The electrics must meet BS 7671, with 30 mA RCD protection on every circuit in the room and at least IPX4 fittings in the zone above the bath, up to 2.25 m. The water fittings rules in each nation limit a new WC to a 6-litre flush and require protection against dirty water flowing back into the supply.
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.
