What does an en-suite cost in Caerphilly?
As a guide, budget £4,200 to £8,400 including VAT for an en-suite in Caerphilly; your written quote will pin it down. 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 Caerphilly
In Caerphilly we cover CF15 and CF83; we also cover Risca, 5.5 miles away, and Pontypridd.
In Caerphilly, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If you live in a Caerphilly flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents. If your Caerphilly en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Supplies across Gwent range from soft to hard depending on the source. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Caerphilly. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A door that suits a tight space: inward, outward, sliding or a pocket door
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- 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.
Door type
An outward-opening door frees floor space inside. A sliding pocket door saves space on both sides but needs a stud wall long enough to take the cassette.
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.
