Working in St Austell
We work right across St Austell — PL25 — and in neighbouring Bodmin and Truro.
Being a smaller town does not change how we work in St Austell: free survey, written quote, one team. If your St Austell cloakroom has no window, we size and duct the extractor fan so the room clears properly. Where your St Austell home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.
Most of Cornwall is supplied with soft water. 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
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- 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.
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.
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.
