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

Working in Llanelli
We work right across Llanelli — SA15 — and in neighbouring Gorseinon and Swansea.
In Llanelli, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. A design survey in Llanelli covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork. We measure Llanelli bathrooms on site before drawing anything, so layouts are based on your walls rather than a standard plan.
Most of Dyfed is supplied with soft water. 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
- Layout options drawn to scale, showing the bath or shower, WC, basin, storage and towel rail
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- A measured survey of the room, including ceiling heights, slopes, window and door positions and any boxing
- A clear view of which changes are cheap and which mean moving drainage or opening floors
Decisions to make first
Where the shower goes
A shower on an outside wall is easier to ventilate; one under a sloping ceiling needs full head height where you stand, not just at the high side.
Planning for later
Timber noggins in the walls for future grab rails, a wider door or a level shower floor cost far less to build in now than to add later.
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.
