What does a new bathroom design cost in Derry?
Design comes with the job: the survey, layout and itemised quote are free. In Derry, a complete designed, supplied and fitted bathroom typically costs £5,700–£10,500 including VAT. We adjust the national guide for Northern Ireland, where prices are typically about 12% below the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Derry
We work right across Derry — BT47 and BT48 — and in neighbouring Limavady and Coleraine.
In a city the size of Derry, parking and access for a skip are worth sorting before the start date — we will ask at the survey. If you are in Derry and weighing a bath against a walk-in shower, the layout options show both with their prices. We measure Derry bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan.
Water across much of County Londonderry is soft. That leaves you free to choose matt black, brushed brass or clear glass without worrying much about limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- Elevations and tile layouts on a design, supply and fit project, so the setting-out is agreed before tiling starts
- A clear view of which changes are cheap and which mean moving drainage or opening floors
Decisions to make first
Keep or change the layout
Keeping the WC and shower where they are saves on plumbing. The WC is the costly one to move, because it is tied to the soil stack.
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.
Rules that apply in Northern Ireland
In Northern Ireland, building control covers new drainage, structural changes and ventilation, which is set out in Technical Booklet K. There is no Part P, but the electrical plan should be designed, tested and certified to BS 7671.
