From Baths to Showers: How Much Can a Family Save on Water and Bills?

Switching from baths to showers isn’t just better for the environment, it can also save a typical UK household hundreds of pounds a year. 

Let’s break down the numbers for a family of four (two adults, two children).

🚿 Water Usage: Baths vs Showers

Activity Average Use per Person Daily Total for 4 People Annual Total

Bath 80 litres 320 litres 116,800 litres

Shower 40 litres 160 litres 58,400 litres

Switching from baths to showers saves: 58,400 litres per year

Water Costs in the UK (2024–2025)

Average combined water and sewerage cost: £3.50 per 1,000 litres

Cost per litre: £0.0035

 Money saved annually:

58, 400 litres × £0.0035 = £204.40

58,400 litres × £0.0035=£204.40

Annual Savings for Your Family

Want to Save Even More?

Install a water-efficient showerhead (uses 25–30 litres per shower)

Time your showers, each minute saved cuts ~10 litres

Use a shower timer or playlist to keep things short and sweet

Over a decade, this simple switch could save your household more than £2,000 in water bills alone – and help conserve over half a million litres of water.
