What does an en-suite cost in Grays?
For Grays, our guide range for an en-suite is £4,800 to £9,500 including VAT. We adjust the national guide for East of England, where prices are typically about 6% above the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Grays
As well as Grays itself (RM16, RM17 and RM20), we survey in Swanscombe, South Ockendon and Gravesend.
Across a large town like Grays, homes range from older terraces to newer estates; the survey tells us which pipework and floor we are dealing with. If the en-suite in your Grays home was squeezed in by a previous owner, a refit is a chance to fix the door swing and the tray size. If your Grays en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Most of Essex has very hard water. If your supply in Grays is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- A survey that traces the route from the en-suite to the soil stack and checks the fall the waste pipes would need
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
Decisions to make first
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.
Night lighting
A mirror light or low-level LED strip on its own switch lets you use the en-suite at night without the full glare of the ceiling lights.
Rules that apply in England
In England, a new en-suite brings in Part H for the new connection to the soil stack, Approved Document F for ventilation, at 15 litres per second intermittent or 8 litres per second continuous extract, and Part P for the new circuits. The electrician should be registered with a competent person scheme, or the work notified to building control. On a refit, avoid replacing the fan with a less effective one.
