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. If you are refreshing a dated cloakroom in Brent, a wall-hung WC and slim vanity can change the room in a few days.
What the job includes
- A concealed cistern frame or WC unit where the space allows
- 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
- 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
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
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.
Basin
A corner basin fits the tightest rooms. A slim vanity basin with a cupboard underneath gives somewhere to keep spare toilet rolls and soap, and hides the trap.
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.
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
A cloakroom refit does not need planning permission, and forming a new one inside the house rarely does, although a listed building needs listed building consent for internal alterations affecting its character. A macerator or pumped WC is acceptable only where the home also has a WC on gravity drainage. The water fittings rules in each nation limit a new WC to a 6-litre flush.
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.
