Working in Mitcham
As well as Mitcham itself (CR4, SM4 and SW17), we survey in Morden, Wimbledon and Streatham.
In Mitcham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If your Mitcham home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. If the en-suite in your Mitcham home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size.
Water across much of Greater London is very hard. If your supply in Mitcham 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.
What the job includes
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
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.
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.
Rules that apply in England
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.
