What does a new bathroom design cost in Cardiff?
Design comes with the job: the survey, layout and itemised quote are free. In Cardiff, a complete designed, supplied and fitted bathroom typically costs £6,000–£11,250 including VAT. Prices in Wales run at about 7% below the national guide, mainly because of labour rates. The figure depends on the size of the room, whether anything moves, and the products you pick.

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. A design survey in Cardiff covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork. If you are in Cardiff and weighing a bath against a walk-in shower, the layout options show both with their prices.
Most of South Glamorgan has moderately hard water. Easy-clean glass and good-quality brassware are money well spent. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A clear view of which changes are cheap and which mean moving drainage or opening floors
- A conversation about who uses the room, when, and what does not work about the current one
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
Decisions to make first
Tile setting-out
Centring tiles on the window, basin or niche avoids thin slivers at the edges. Large tiles mean fewer joints but need flatter walls.
Storage
Fitted furniture, a vanity with a tall cupboard, or recessed niches and a mirror cabinet. Recessed storage costs no floor space but needs a stud wall or deep boxing to sit in.
Rules that apply in Wales
Wales has its own Parts F, H and P. Extract rates are similar to England, but more electrical work is notifiable, so the design should allow for a registered electrician to notify it.
