    Thank you @JennyJ, I will have a look at your example. I have a box of hosepipe connectors because I always seemed to buy the wrong one. Maybe one of them will work for this project... :dizzy!

    @borgadr do you think it depends on how diluted the bath water is and how quickly it arrives in the soil? I am thinking of not using soap (or minimal dp type stuff) and doing 'flannel washes' at other times. I currently only have 1 bath a week but I do use soap at the moment. Hope that does not sound too stinky!

    @clematisdorset unfortunately I can't advise you, as everything I've ever read says it's fine to use bathwater!  I struggle to believe this, and I'm no expert, so you might reasonably say my objections are somewhat irrational.

    No not irrational @borgadr, and I am sure there is some science somewhere lurking! Quite honestly, if I manage to get the pump and hose set up, it will mean I can at least  have more than 1  bath a week without feeling too worried/guilty - even if it means soap-less. Baths are good for aching joints etc. I suppose epsom salts would be ok in the bath and then in the soil - I will have to check.

    This is my second year doing it. Plants are all healthy and thriving.
    I've not seen any detrimental effects.

    Edit, we use bars of soap and the women of the house use shampoo and conditioner. That all goes on the garden.

    Bathwater with soap and a bit of bubblebath goes on the garden, no problems last summer and certainly better than no water at all. I use a lot of thick conditioner on my hair (it's long and tending towards frizzy) and rinse it in the shower so that goes down the plug hole.
    @clematisdorset - the green hose goes out of the window and you squeeze the red part several times to get the water "over the hump" and start the syphoning. Then it empties itself all bar the last tiny bit. The clear parts of the pump don't show up very well but it's like the one in the link that I posted before.

    Thanks @JennyJ I was wondering about getting the water out -up-over. Your bath water looks quite low, but it sounds as though you can get most of it out of the bath and to outside. Thanks for your photo - it does help me visualise what to do.

    that's what the siphon is for. It pushes out the air in the tube and then physics does the rest and pulls the water into the garden, as long as the point of outflow is lower than point of inflow.

    I might have to use a short hollow rubber tube in lieu of a hose, and then angle it out of the window towards a bucket or trough.

    I do like a bath to soak my arthritic joints, but it doesn't have to be brim-full :D (thinking of the gas bill as well as the water usage).
