Working in Trowbridge

In Trowbridge we cover BA14; we also cover Westbury, 4.2 miles away, and Melksham.

Homes in and around Trowbridge vary, so we look at the floor, the walls and the water system before we price anything. If your Trowbridge cloakroom has no window, we size and duct the extractor fan so the room clears properly. Where your Trowbridge home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go.

Water across much of Wiltshire 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

  • A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
  • Strip-out of the old fittings, waste removal and making good on the hall side
  • Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
  • An extractor fan ducted to outside, wired with an overrun timer or linked to the light

Decisions to make first

WC style

A wall-hung WC on a frame gives the most floor space and looks neat. A back-to-wall pan in a short furniture unit is easier to fit against an uneven wall.

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.

Cloakrooms & downstairs WCs in Trowbridge: questions

How much does a cloakroom or downstairs WC cost in Trowbridge?

A cloakroom or downstairs WC in Trowbridge usually costs £1,850–£4,600 including VAT. Where you land in that range depends on the size of the room, whether the layout changes and the products you choose. After the free survey you get an itemised written quote, and the price is fixed in writing once the layout and products are agreed.

Is the water hard in Trowbridge?

Water across much of Wiltshire 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.

Who handles building control for a cloakroom or downstairs WC in Trowbridge?

Building control for Trowbridge is handled by the local council or an approved inspector. If your job needs sign-off — for example a new circuit, new drainage or a new extractor where there was none — we tell you at the survey and handle the notification as part of the work.

How long does a cloakroom or downstairs WC take?

Allow 2–4 working days on site for most jobs, plus the lead time for products after you approve the quote. We give you a day-by-day plan before work starts in Trowbridge.

Can I have a macerator toilet in a downstairs cloakroom?

Yes, provided the house already has a WC on gravity drainage, for example in the main bathroom. A macerator pumps the waste through a small-bore pipe, so it can serve a cloakroom some distance from the soil stack. It needs a fused electrical supply, makes a noise while it runs and should only take toilet waste and paper.
