What does a cloakroom or downstairs WC cost in Ewell?
As a guide, budget £2,000 to £5,000 including VAT for a cloakroom or downstairs WC in Ewell; your written quote will pin it down. We adjust the national guide for South East England, where prices are typically about 12% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Ewell
We cover every part of Ewell, including KT4, KT17 and KT19, and nearby Epsom (1.6 miles) and Sutton (2.1 miles).
In Ewell, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. We survey cloakrooms in Ewell with the headroom in mind as well as the floor area, because under-stair spaces lose height quickly. If your Ewell cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Water across much of Surrey 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
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A concealed cistern frame or WC unit where the space allows
- Lighting wired by a qualified electrician, tested and certified
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
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.
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.
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.
