Working in Southampton
In Southampton we cover SO14, SO15, SO16 and 3 more postcode districts; we also cover Hythe, 3 miles away, and Totton.
Southampton is a big place with every kind of home, from terraces to flats to new builds, so we never price from a photo alone. Where your Southampton home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. If your Southampton cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Most of Hampshire has hard water. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Strip-out of the old fittings, waste removal and making good on the hall side
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Lighting wired by a qualified electrician, tested and certified
- Splashback or feature tiling and a new floor, often LVT or porcelain
Decisions to make first
Finishes
A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
Rules that apply in England
In England, a new WC connected to the soil stack or drain is drainage work under Part H, and a newly formed cloakroom without an opening window should have mechanical extract; Approved Document F gives 6 litres per second as the design rate for a WC, against 15 for a bathroom. Because a cloakroom has no bath or shower, adding a light to an existing circuit is not notifiable under Part P, but a new circuit is.
