Working in Southampton
In Southampton we cover SO14, SO15, SO16 and 3 more postcode districts; we also cover Hythe, 3 miles away, and Totton.
In a city the size of Southampton, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If the en-suite in your Southampton home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If you live in a Southampton flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Most of Hampshire has hard water. If your supply in Southampton 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
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- 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
Decisions to make first
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
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.
