What does an en-suite cost in Llanelli?
For Llanelli, our guide range for an en-suite is £4,200 to £8,400 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 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. If your Llanelli home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue. If your Llanelli en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Water across much of Dyfed is soft. If that holds for your street in Llanelli, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- IP-rated lighting, a shaver socket and the electrics done by a qualified electrician, tested and certified
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
Decisions to make first
Shower size
A 900 mm square tray is a comfortable minimum for an enclosure. In a long, narrow room, a 1200 by 800 mm walk-in tray with one glass panel feels far more generous.
Exposed or concealed valve
An exposed bar valve is quicker to fit and easy to service. A concealed valve looks cleaner but sits inside the wall, so plan how it will be reached for repairs.
Rules that apply in Wales
Wales has its own Part F with similar extract rates and its own Part P, which makes more electrical work notifiable than in England. The drainage for a new en-suite falls under Part H. The work should be notified, and you should receive the certificates at the end.
