What does an en-suite cost in Durham?
For Durham, our guide range for an en-suite is £4,000 to £8,100 including VAT. We adjust the national guide for North East England, where prices are typically about 10% below the UK average. The figure depends on the size of the room, whether anything moves, and the products you pick.
Refit
- Tiling, lighting and extractor fan
Upgrade
- Walk-in shower or larger tray
New en-suite
- New stud walls, drainage and pump if needed

Working in Durham
We cover every part of Durham, including DH1, and nearby Spennymoor (5.5 miles) and Chester-le-Street (5.7 miles).
In a city the size of Durham, parking and access for a skip are worth sorting before the start date — we will ask at the survey. We quote new en-suites in Durham only after checking the drainage route on site, so the price reflects the work your house actually needs. If your Durham en-suite fan just blows into the loft, we can duct it properly to outside as part of the refit.
Most of County Durham has moderately hard water. A quick wipe of the glass and an easy-clean coating are worth having on a new shower in Durham. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A door that suits a tight space: inward, outward, sliding or a pocket door
- Stud walls with acoustic insulation and moisture-resistant board for a new en-suite
- An extractor fan ducted to outside, sized to the room and wired with an overrun timer or humidistat
- A pumped waste or macerator where gravity drainage is not possible, and only where the house already has a WC on gravity drainage
Decisions to make first
Refit or new en-suite
A refit keeps the existing drainage and walls. A new en-suite costs more because the walls, waste route, fan duct and electrics all start from nothing.
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.
