Which towns do we cover in Cornwall?
Most of Cornwall is supplied with soft water. If that holds for your street in Redruth, limescale on shower glass and heads builds up slowly and a squeegee after use is usually enough. Hardness varies street by street, so check the figure for your postcode with your water supplier. For Redruth homes with a cold tank in the loft, we check the system before fitting anything, because a pump is only allowed on a gravity supply.
What the job includes
- Tiling or re-tiling around the shower, with tanking behind new tiles in the wet area
- Electrical connection by a qualified electrician, tested and certified
- A bath screen, tray or enclosure where the shower is new
- Removal of the old shower, a full-flow test and a handover on isolating and descaling it
- Supply and fitting of the shower valve or unit, riser rail, handset or fixed head
- A check of your hot-water system, water pressure and flow rate
Decisions to make first
Power shower
A mixer with a built-in pump, for tank-fed systems only. It lifts a weak gravity shower but must never be connected to the mains.
Electric shower
Heats cold mains water as it flows, so it works without stored hot water. Higher kW units give more flow; 8.5 to 10.5 kW models need a dedicated circuit, often 40 to 45 amps.
Thermostatic mixer
Blends hot and cold from your system and holds the temperature steady when someone runs a tap. The usual choice with a combi or an unvented cylinder.
Exposed or concealed
An exposed bar valve fixes onto the tiles and is easy to service. A concealed valve sits in the wall for a cleaner look but needs careful setting-out and a plan for access.
Rules that apply in England
The water fittings regulations in each nation do not allow a pump to be connected directly to the mains supply; shower pumps are for gravity systems with a cold tank only. The shower must also be protected against water flowing back into the supply. Electrics must meet BS 7671, with 30 mA RCD protection and at least IPX4 fittings in zone 1, or IPX5 where water jets are used.
In England, an electric shower usually needs its own dedicated circuit, often 40 to 45 amps for an 8.5 to 10.5 kW unit, and a new circuit is notifiable under Part P. The Part G limit of 48 °C applies to a new bath in a new dwelling or one created by change of use, not to a shower, but a thermostatic valve gives similar protection. An unvented cylinder fitted to improve the shower must be installed by a G3-qualified installer.
