Working in Streatham
As well as Streatham itself (SE27, SW12 and SW16), we survey in Mitcham, Brixton and Wimbledon.
In Streatham, many bathrooms are in flats or converted houses, so we check lease consents, access and the floor below before we price. If the only toilet in your Streatham home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips. If your Streatham cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Supplies across most of Greater London are very 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
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- Strip-out of the old fittings, waste removal and making good on the hall side
- A concealed cistern frame or WC unit where the space allows
- Lighting wired by a qualified electrician, tested and certified
Decisions to make first
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.
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.
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.
