Working in Marlow
We work right across Marlow — SL7 — and in neighbouring Maidenhead and High Wycombe.
Marlow gets the same process as anywhere else: a free survey at your home and a written, itemised quote. If the only toilet in your Marlow home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips. We survey cloakrooms in Marlow with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly.
Supplies across most of Buckinghamshire are 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
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
- Splashback or feature tiling and a new floor, often LVT or porcelain
- 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.
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.
