How to use it
- An overhead (rain) shower is fixed to the wall or ceiling with an arm; a hand shower connects to a hose and a holder or a diverter outlet.
- Large rain showers need more water to feel full; in a home fed by an overhead tank, a smaller head or a pressure pump gives a better spray.
- Check that the shower’s connection matches the arm, hose or diverter it will fit to.
Installation
- Mark the arm or holder height before tiling, so the outlet comes out where the shower should sit.
- Seal the threaded joint with PTFE tape and tighten by hand; overtightening damages the head’s connection.
- Run water through the line before fitting the head, so debris does not block the nozzles.
Care and maintenance
- Rub the rubber nozzles with a finger every few weeks to clear scale; most modern shower heads are made for this.
- Clean the finish with mild soap and a soft cloth. Acid cleaners and scouring powders damage chrome and coloured finishes.
- In very hard water, soak a removable head in a mild vinegar solution only if the maker allows it for that finish.
Buying tips
- Bigger is not always better: a large head on low pressure gives a weak spray.
- Multi-flow hand showers let you switch between spray patterns; check how many flows the product lists.
- Buy the arm, hose or holder of the same finish, so the set matches.

Frequently asked questions

It will work, but the spray is gentler on low pressure, and more so with a large head. A booster pump helps where pressure is low.
Rub the rubber nozzles with a finger to break off the scale. For stubborn scale, follow the maker’s cleaning advice for that finish.
