If you had to choose….

I would water my garden then step under the hosepipe for a quick rub down!!

Shower. Have the water drain to a water butt and reuse for the garden.

I take a bucket into the shower and catch the water before it gets to temperature, so I have half a bucket of water for the greenhouse, the wee plants get a bit , but the lawn has to take a hit , so I’m kind of getting both targets , I itch if I don’t shower !

Same as Scentia. Or I'd have an outside shower built with a collection tub for the waste water (but only in a hot country!)

Definitely shower for me. When I had a garden I had a water butt so always had some water for my plants.

We have a rainwater collection tank but have been advised to ration it as our water might be turned off and we have no means of flushing the loo if the mains is turned off , so a bucket of rain water is precious !

I have a leak in my hose pipe so every day me and our dog get a shower when watering the garden. It’s fine by me and my clothes go in the washing machine.
