Can you give rabbits water in a bowl?

Definitely! Bunnies are just like us as in they need food and water, but not necessarily the same kind of food as us!

If you go down to your local pet store they will have bunny/rabbit drinking bottles which you can just attach to the side of the cage for them to drink out. You could also use a dish for water (as you would for a cat or dog). Some rabbits prefer one over the other, and in order to encourage them to drink enough water, you should give them whichever they prefer. Dehydration can lead to gut impaction in bunnies, and you definitely want to avoid that!

If you use a bowl and your rabbit likes to throw things, make sure to use either a heavy ceramic crock that the rabbit can't throw, or else use a metal dish that won't break when thrown.

Whatever you use, make sure you wash the bowl/bottle daily and replace the water daily -- don't just top it up because the water will turn stale and it won't taste nice, and the rabbit won't want to drink it. Pay especially attention to cleaning the nozzle on a bottle, if you use one, because it can develop mould and/or rust.
