Which towns do we cover in Gwynedd?
Most of Gwynedd is supplied with soft water. If that holds for your street in Bangor, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier. If your Bangor en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
What the job includes
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
Decisions to make first
Door type
An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.
Noise
Acoustic insulation in the stud walls and a quiet fan make a real difference when one of you showers early while the other is still asleep.
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
Rules that apply in Wales
Forming an en-suite inside an existing bedroom does not normally need planning permission, but it is usually building-regulations work because it adds drainage, ventilation and electrics. All wiring must meet BS 7671, with 30 mA RCD protection on every circuit in the room. A macerator or pumped WC is acceptable only where the home also has a WC on gravity drainage. In a listed building, a new soil or vent pipe through a wall needs listed building consent.
Wales has its own Part F with similar extract rates and its own Part P, which makes more electrical work notifiable than in England. The drainage for a new en-suite falls under Part H. The work should be notified, and you should receive the certificates at the end.
