Rain shower heads don’t actually use more water than standard shower heads.
However, you might prefer not to invest in a rain shower head if you live in an area where water costs are notably high. This is because you’ll likely spend more time showering with the luxurious spa-like quality of a rain deluge at your disposal.
You can source water-saving rain shower heads, if you have your heart set on the style but are concerned about a potential impact on your water bills.
