Supplies across most of South Glamorgan are moderately hard. Easy-clean glass and good-quality brassware are money well spent. Hardness varies street by street, so check the figure for your postcode with your water supplier. If you have just bought a house in Cardiff, renovating the bathroom before moving in saves living through the dust.

What the job includes

• Re-plastering or boarding, with cement-based boards and tanking in the wet areas
• New hot and cold pipework and wastes, with isolation valves to each fitting
• Strip-out back to brick or studwork, with waste taken away by a licensed waste carrier
• Tiling, fitting of the suite and furniture, making good and decorating, then handover
• Repairs to rotten floorboards, joists or other timber found once the room is open
• A survey of the structure and services: joists, walls, ceilings, pipework, wastes, wiring and ventilation

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.
