Working in Cardiff

We cover every part of Cardiff, including CF10, CF11 and CF24, and nearby Penarth (2.9 miles) and Caerphilly (6.7 miles).

In a city the size of Cardiff, parking and access for a skip are worth sorting before the start date — we will ask at the survey. We quote wet rooms in Cardiff only after looking at the floor construction, because that is where most of the cost difference lies. In a compact Cardiff bathroom, a wet room frees the space a tray and enclosure would take, but expect the whole floor to get wet.

Supplies across most of South Glamorgan are moderately hard. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Cardiff. Hardness varies street by street, so check the figure for your postcode with your water supplier.

What the job includes

A survey of the floor construction, the joist size and direction or the concrete slab, and the route to the soil stack
A pre-formed floor former with a linear or centre drain, or a screed laid to fall
A frameless glass screen fixed to the wall and floor
Full tanking of the floor and the shower walls, with sealed corners, pipe collars and a sealed drain connection

Decisions to make first

Screen size

A screen of 1200 mm or more keeps spray off the rest of the room in most layouts. In a very small wet room, expect the whole floor to get wet.

Open or screened

A fully open shower with no glass only works in a larger room, with the basin, WC and towels well away from the spray.

Rules that apply in Wales

In Wales, Part H covers new drainage and the Welsh Part F sets similar extract rates. The Welsh Part P makes more electrical work notifiable than in England, so the electrician should notify and certify the work.

Is the water hard in Cardiff?

Who handles building control for a wet room in Cardiff?

Building control for Cardiff 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.

What is tanking in a wet room?

Tanking is the waterproof layer under the tiles that stops water reaching the floor and walls. It is usually a liquid or sheet membrane, with sealing tape at every corner, board joint and pipe. Tiles and grout are not waterproof on their own, so the tanking is what actually keeps the water in.
