What does a new bathroom design cost in Merthyr Tydfil?
Design comes with the job: the survey, layout and itemised quote are free. In Merthyr Tydfil, 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 Merthyr Tydfil
As well as Merthyr Tydfil itself (CF47 and CF48), we survey in Aberdare, Rhondda and Ebbw Vale.
Homes in and around Merthyr Tydfil vary, so we look at the floor, the walls and the water system before we price anything. If you are in Merthyr Tydfil and weighing a bath against a walk-in shower, the layout options show both with their prices. A design survey in Merthyr Tydfil covers drainage, supplies, electrics and ventilation, so nothing on the drawing is guesswork.
Water across much of Mid Glamorgan 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 lighting and electrical plan showing switches, fittings, shaver socket and extractor fan
- Checks on the soil stack, waste routes, joist direction, water pressure, hot water system and existing electrics
- A written, itemised quote, with the price fixed in writing once the layout and products are agreed
- A clear view of which changes are cheap and which mean moving drainage or opening floors
Decisions to make first
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.
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.
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.
