Being a smaller town does not change how we work in Thornaby-on-Tees: free survey, written quote, one team. If your Thornaby-on-Tees loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. For a loft bathroom in a tank-fed Thornaby-on-Tees home, we work out how the shower will get its pressure before choosing a single fitting.
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
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- Fitted furniture made to the eaves, so the low space behind the slope becomes storage
- A check of the floor joists where a bath or large shower tray will sit
Decisions to make first
Gravity or pumped waste
Gravity is silent and maintenance-free. A pumped waste or macerator lets fittings sit away from the stack, provided the house has a WC on gravity drainage elsewhere.
Roof window
A roof window over the bath or shower brings daylight and fresh air, but plan the blind for privacy and expect condensation on cold glass.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
