Which towns do we cover in Dorset?
Supplies across most of Dorset are hard. If your supply in Bournemouth is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier. We quote new en-suites in Bournemouth only after checking the drainage route on site, so the price reflects the work your house actually needs.
What the job includes
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A door that suits a tight space: inward, outward, sliding or a pocket door
- 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
Decisions to make first
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.
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.
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.
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
Rules that apply in England
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.
In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.
