Working in Walthamstow
We work right across Walthamstow — E4, E10, E11 and 1 more postcode districts — and in neighbouring Leytonstone and Tottenham.
London homes in Walthamstow often mean stairs, permits and neighbours below; we plan the logistics as carefully as the bathroom. For a new cloakroom in Walthamstow, the first thing we look at is where the nearest drain or soil stack runs. If the only toilet in your Walthamstow home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips.
Most of Greater London has very 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
- An extractor fan ducted to outside, wired with an overrun timer or linked to the light
- A concealed cistern frame or WC unit where the space allows
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
Decisions to make first
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
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.
