Working in Trowbridge
In Trowbridge we cover BA14; we also cover Westbury, 4.2 miles away, and Melksham.
Homes in and around Trowbridge vary, so we look at the floor, the walls and the water system before we price anything. If your Trowbridge cloakroom has no window, we size and duct the extractor fan so the room clears properly. Where your Trowbridge home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.
Water across much of Wiltshire is 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
- Strip-out of the old fittings, waste removal and making good on the hall side
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
Decisions to make first
WC style
A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.
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.
