What does a cloakroom or downstairs WC cost in Southsea?
Our guide price for a cloakroom or downstairs WC in Southsea is £2,000–£5,000 including VAT. 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 Southsea
As well as Southsea itself (PO1, PO4 and PO5), we survey in Portsmouth, Gosport and South Hayling.
Southsea gets the same process as anywhere else: a free survey at your home and a written, itemised quote. Where your Southsea home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. If the only toilet in your Southsea home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips.
Supplies across most of Hampshire 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
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- Strip-out of the old fittings, waste removal and making good on the hall side
- Lighting wired by a qualified electrician, tested and certified
- Splashback or feature tiling and a new floor, often LVT or porcelain
Decisions to make first
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.
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.
