Happy 2020! I got one of those gravity feeders that dispense water and can hold a lot. My bunny drinks a lot of water but would tip over his bowls (he's an eager little thing) so I felt like this would solve both the problem of me having to keep refilling and prevent him from tipping. The water feeder has a carbon filter to keep the water from getting stale etc. Is it safe for bunnies? I've linked the one I'm talking about.
