Bathroom Timer

The average shower in most surveys lasts 8 to 10 minutes and uses around 65 to 100 litres of water, depending on the shower head. Water-saving guidance from utilities usually suggests four to five minutes, which is plenty for washing and cuts water and heating energy roughly in half. Dermatologists say much the same for skin: long hot showers strip the skin's oils, and five to ten minutes in warm rather than hot water is easier on eczema and dry skin. The presets here run from 3 to 15 minutes; the loud, rising alert is designed to be heard over running water and a fan.

Heating that water is the larger cost: for a household on an electric water heater, a family of four moving from 10-minute to 5-minute showers can cut annual hot-water energy by a noticeable margin. A low-flow head (6–7 L/min) saves a similar amount without a shorter shower.

For children, a visible countdown turns "out of the bath now" into something the clock says rather than the parent. Set it for the agreed time and let them press start. In shared flats and student halls, a 5-minute timer in the morning queue is a small courtesy that stops the "you have been in there for twenty minutes" argument; pair it with the alarm clock's Lights Off mode for a wake-up routine that runs on rails. The brushing timer covers the next two minutes of the routine.
