Working in Grangemouth
In Grangemouth we cover FK3; we also cover Falkirk, 2.5 miles away, and Alloa.
Grangemouth gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If you live in a Grangemouth flat, check your title deeds and any deed of conditions before planning a new en-suite, as agreement from the other owners or the factor is often needed for new drainage and vents. If your Grangemouth en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Most of the Forth Valley is supplied with soft water. If that holds for your street in Grangemouth, 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.
What the job includes
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- A door that suits a tight space: inward, outward, sliding or a pocket door
Decisions to make first
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 Scotland
In Scotland, forming a new en-suite may need a building warrant because it creates a new bathroom and alters drainage; refitting an existing one rarely does. The Technical Handbook uses the same 15 litres per second extract rate for a bathroom, and the electrics should be tested and certified to BS 7671.
