Which towns do we cover in Gwynedd?
Supplies across most of Gwynedd 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. In Bangor flats, the lease and the flat below are considered before a renovation is planned, particularly for moving the WC or adding a vent.
What the job includes
- New wiring, lighting, extractor fan and RCD protection, installed and certified by a qualified electrician
- New hot and cold pipework and wastes, with isolation valves to each fitting
- Layout changes such as moved doors, new stud walls or boxing for concealed cisterns
- Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
- A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation
- Repairs to rotten floorboards, joists or other timber found once the room is open
Decisions to make first
Shower floor
With the floor already up, a renovation is the easiest time to form a level shower floor or a full wet room.
Heating
Moving the radiator, adding a heated towel rail or laying underfloor heating is simpler while the room is stripped.
Pipe material
Copper suits exposed runs and the area near the boiler. Plastic pipe is quicker under floors and inside walls, and long runs need fewer joints.
How far back to strip
Back to brick gives a clean start. Keeping sound plaster on some walls saves time and money, and the survey shows which walls can stay.
Rules that apply in Wales
Renovating a bathroom inside an existing home does not need planning permission. Listed buildings need listed building consent for alterations that affect their character, which can include internal work and new soil or vent pipes through walls. In a flat, check the lease: freeholder consent is often needed for wet rooms, moving the WC or new extract vents, and sound insulation and leak risk to the flat below matter. Electrical work must meet BS 7671, with 30 mA RCD protection on every bathroom circuit.
Wales applies its own building regulations, including a wider Part P and its own Parts F and H. Structural and drainage changes go through building control in much the same way as in England.
