Working in Dorchester
As well as Dorchester itself (DT1), we survey in Weymouth, Yeovil and Poole.
Being a smaller town does not change how we work in Dorchester: free survey, written quote, one team. If your Dorchester cloakroom has no window, we size and duct the extractor fan so the room clears properly. Where your Dorchester home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.
Water across much of Dorset 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 concealed cistern frame or WC unit where the space allows
- 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
- Lighting wired by a qualified electrician, tested and certified
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.
