Bath vs shower water consumption graph

We ran an online poll to see what Team Power Smart members believe uses more hot water: a seven-minute shower or a 20-minute bath. The results are in, and BC Hydro senior engineer David Rogers exposes the truth.

The majority of Team Power Smart customers (60%) chose the shower, and were incorrect, says Rogers: a seven-minute shower actually consumes less hot water. The average bath uses between 80 and 150 litres, while the shower uses around 66. For a family of four, showers save about $190 per year. Low-flow shower heads save even more, using 20 to 50% less hot water than standard heads. Showering in cooler water helps too, says Rogers: each percentage drop in temperature will translate to roughly the same percentage drop in your home’s water-heating costs.
