Working in Horsham
In Horsham we cover RH12; we also cover Crawley, 7.2 miles away, and Horley.
Homes in and around Horsham vary, so we look at the floor, the walls and the water system before we price anything. If your Horsham cloakroom has no window, we size and duct the extractor fan so the room clears properly. Where your Horsham home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.
Supplies across most of West Sussex are hard. 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
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- 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.
