Relataive cost of baths versus showers

jellitot

I've looked everywhere to get this info without luck so I thought I'd put it here.

I'm a shower person and also pay the bills. A while back I tested out my (non power) shower and determined that a 2 minute shower run filled a waste bin about 4 inches. So not a lot of water. This is about my daily usage.

However my step children (grown up) insist on having baths - sometimes more than one a day!

I'm interested in the total cost of each including the amount of water - and drainage charge.

My intention is to dump them with the extra cost - then I can retire.

Any ideas?

I like it...

My electric shower 4 litres a minute. 8.5kW. Cost for 6 minutes @15p/kWh day rate. 12.75p and 24 litres.

My thermostatic shower heated by E7 water. 12 litres per minute. Cost for 6 minutes @5p/kWh night rate for heated water. About 12.75p and 72 litres. That's also the same amount of warm water used for the bath so the cost of the bath is about the same. It's also the same if gas is used and costs 3.5p/kWh and is 70% efficient at heating the water in the cylinder.

So the only real cost difference is the cost of the water. An extra 48 litres per day. 365 days a year is 17.5 cubic metres and at a cost of £2 a cubic metre that's £35 a year.

P.S national averages for showers is 35 litres and baths 80 litres so it's about the same.
