YOU ARE NOT SUPPOSED TO PUT RABBITS IN WATER. “This can be extremely traumatic for a rabbit and can put them into shock; many rabbits have died from this kind of trauma.”
To repeat this: YOU ARE NOT SUPPOSED TO BATHE YOUR RABBITS.
Bathing your rabbit can make it extremely uncomfortable and anxious, which can lead to the rabbit panicking and injuring itself or going into shock. Rabbits may also become extremely ill as they are sensitive to temperature change and may become cold once out of the water (i.e. they could get hypothermia and die, or get a respiratory infection and die without proper treatment — rabbits are sensitive little critters). rabbit.org also has an informative post on how to groom your bun, and what you should and shouldn’t use on it to groom: http://rabbit.org/faq-grooming/
RABBITS ARE SELF-GROOMING LIKE CATS. They generally keep THEMSELVES clean (companions will also clean each other). IF you have found that your bun has managed to get itself into a pickle and can’t clean itself, there is a wikihow on how to properly bathe a bunny so that it is calm, relaxed and above-all: NOT. FUCKING. SOAKED.
The ONLY TIME you should bathe your rabbit is IF A VET HAS GIVEN YOU THE OKAY TO DO SO. Another informative link is here: http://www.rabbitwelfare.co.uk/pdfs/BathingBunnies-RO.pdf Even this link says it is unnecessary to wet your whole rabbit for any reason. Contrary to how this little guy is going, the vast majority of bunnies are unable (and unhappy) to be submerged in water and do not enjoy it, so please, PLEASE do not soak your bun. There’s no need to, it will just cause stress and what kind of person are you if you want to stress your animal out like that?
This has been a PSA.
