Can you use your bath water to water your garden?

I am pretty sure it is a question that a lot of gardeners have been wondering recently. All over the country there is talk of hose pipe bans. At the moment only Northern Ireland has one, but general consensus is that it won’t be long before they are imposed.

Water companies are suggesting that people try to be conscious of the water they are using, and try to restrict it as much as possible.

  • Showers rather than baths
  • Turn off the taps when brushing your teeth
  • Wash your car with a bucket of water rather than a hose pipe
  • Water your garden with a watering can rather than a hose pipe

But it is so much easier to use a hose right? It takes so long to keep going back and filling the watering cans up.

So is there a way around it?


We are still using our hose pipe to water our garden, but we are saving so much water.

Due to the products used in the bath, and the fact you are dirty….it is advised that you don’t water food plants with your bath water (tomatoes, herbs, beans, potatoes, etc.) just your flowers, shrubs etc.

So how do you manage to water your garden with a hose pipe?

This is how we did it, and if our neighbours saw us doing this, they may have thought we were made….but I reckon during the Summer months we could nearly half our water consumption!

The other end of the hose needs to remain attached to the usual tap you use for your hose.

Turn the tap on until the water starts coming out the other end into the bath, then immediately disconnect the hose from the tap. Water will then start to drain out of the bath, using gravity and flow in reverse. You can then add the spray connected on to the end of the hose, and use as you usually would.

We found that the water pressure was lower than it usually is if the hose is connected to the usual tap. But this was an advantage as well, as it meant that less water was wasted when you moved the hose from plant to plant etc.

If you are doing this on your own…or someone doesn’t want to make sure the hose stays in the water, then it is helpful to weigh down the hose. We used a rubber weight, but you can use whatever you think would work for you

The bath water managed to water the whole of our front garden, where the majority of our plants are, and also watered the back garden as well.

We tend to give Isla a bath pretty much every night. It’s been part of her bedtime routine for a long time, and it lets her know that it’s time for her to go to bed soon. The nights she doesn’t have a bath she often takes a lot longer to settle and go to sleep.

Have you tried anything like this before?


So, can you use your bath water to water your garden? Yes, and it’s fairly simple!
