Which towns do we cover in Gwynedd?
Most of Gwynedd 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. If you live in a terrace or semi in Bangor with a compact bathroom, swapping a pedestal basin and close-coupled WC for wall-hung pieces is often the biggest single gain.
What the job includes
- Space-saving sanitaryware: a short-projection or wall-hung WC and a compact or semi-recessed basin
- A measured survey including the door swing, window position, soil stack and any boxing that could be slimmed down
- Two or three layout options, each priced, so you can compare keeping the bath with a walk-in shower
- Shorter, narrower or shower baths where a full 1700 mm bath does not sit well
- Lighting, extractor fan and towel rail wired by a qualified electrician, tested and certified
- Strip-out, waste removal, testing and a clean handover
Decisions to make first
Glass
Clear glass with a slim profile or none lets the eye travel through the room. A fixed panel needs no clearance for a door to swing.
Storage
Recess shelves into stud walls or boxing, put a mirror cabinet over the basin and use the wall above the WC. Avoid floor-standing units in very tight rooms.
Keep the bath or go walk-in
A 1500 or 1600 mm bath keeps a bath in a short room. A walk-in shower with a single glass panel opens up the floor and makes the room read as larger.
Tiles and grout
Larger tiles with a grout close to the tile colour make walls look calmer. Running the same floor tile into the shower makes the floor look continuous.
Rules that apply in Wales
A small bathroom refit in the same room does not need planning permission. The electrical zones matter more in a tight room because the lights and fan end up close to the shower: fittings above the bath or tray up to 2.25 m must be at least IPX4, and any socket other than a shaver supply unit must be at least 3 m from that zone, which in a small bathroom usually rules sockets out. Every circuit needs 30 mA RCD protection under BS 7671.
Wales has its own Part P, with a wider list of notifiable work than England, and its own Part F with similar extract rates. Expect the electrical work to be notified and certified.
