In Sunbury-on-Thames, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Sunbury-on-Thames home has hard water, we talk through brassware and stone finishes that will still look good after a year of daily use. For a period house in Sunbury-on-Thames with high ceilings, we plan the lighting and tile heights to suit the proportions of the room.
Most of Surrey has hard water. We plan easy-clean glass, rimless toilets and finishes that do not show limescale. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A full snag check, sealing of stone where needed, and a handover of manuals and isolation points
- Concealed thermostatic or digital shower valves, set into the wall to the depth the manufacturer specifies
- Underfloor heating, layered lighting and any steam unit wired by a qualified electrician, tested and certified
- Large-format porcelain, natural stone or microcement over full tanking
Decisions to make first
Shower system
A concealed thermostatic valve with a ceiling head and handset is the usual choice. A digital valve sets the temperature from a wall panel, and a steam enclosure needs its own generator and supply.
Heating
Underfloor heating under stone or porcelain makes the room comfortable all year; pair it with a towel rail for drying.
Rules that apply in England
In England, the new circuits a luxury bathroom often needs, for underfloor heating, a steam unit or a digital shower, are notifiable under Part P. An unvented hot-water cylinder, often fitted to feed a large shower, must be installed by a G3-qualified installer, and any work on the boiler must be done by a Gas Safe registered engineer.
