For an en-suite in Thornaby-on-Tees, the first question at the survey is always where the waste can reach the soil stack. If your Thornaby-on-Tees home has one bathroom and a good-sized main bedroom, an en-suite is often the change that eases the morning queue.
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 Thornaby-on-Tees. 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
- A short-projection or wall-hung WC and a compact basin chosen to keep the floor clear
- A shower tray or level-access former, an enclosure or walk-in panel, and a thermostatic valve
- A door that suits a tight space: inward, outward, sliding or a pocket door
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.
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.
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.
