What does an en-suite cost in Harwich?
In Harwich, an en-suite typically costs £4,800–£9,500 including VAT, based on East of England prices. Labour costs in East of England put local prices at about 6% above the UK guide figure. The figure depends on the size of the room, whether anything moves, and the products you pick.

Working in Harwich
We cover every part of Harwich, including CO12, and nearby Felixstowe (3.2 miles) and Walton-on-the-Naze (6.5 miles).
Being a smaller town does not change how we work in Harwich: free survey, written quote, one team. If your Harwich en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit. If you live in a Harwich flat, check the lease before planning a new en-suite, as freeholder consent is often needed for new drainage and vents.
Water across much of Essex is very hard. If your supply in Harwich 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
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- Tiling, silicone, testing and making good on the bedroom side of any new walls
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
Decisions to make first
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.
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.
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.
