Working in Penzance
We work right across Penzance — TR18 — and in neighbouring Camborne and Redruth.
Being a smaller town does not change how we work in Penzance: free survey, written quote, one team. We survey cloakrooms in Penzance with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. Where your Penzance home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.
Water across much of Cornwall is soft. In soft water, taps, wastes and toilet pans scale up slowly, so brushed and matt finishes are a safe choice. 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
- A concealed cistern frame or WC unit where the space allows
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
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.
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.
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.
