Warranty and validity

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.
