I don't have any personal experience with a toucan, (you're getting a lot of that today, I know. Lol) but I met a bird owner with one (along with a beautiful, and atypically LARGE, eclectus parrot) at the bird store where I had purchased my own eclectus.
The one he had was among the smallest of that species, called an aracari (I believe) toucan. It was beautiful and comically hyper, darting about its large boarding cage in that ADD fashion seen most commonly in hummingbirds.
I chewed his ear off with questions when he came to collect his birds from the boarding room, as his little toucan was obviously very well socialized and recall trained. He keeps his toucan in his home. It is indoor flight-trained and has all day full run of the entire house. (As an alternative, I reckon, to Birdman's point about them needing the space of an outdoor aviary. Likely helped that it is so small a toucan, though. Not counting that beak, it was probably smaller than a cockatiel.)
As for sleeping arrangements, he said that it spends all night in his sock drawer. Lol! Never asked if that was the bird's innovation, or his own! But I have my suspicions.
He did confirm the squirty poop observations of Sambamama, but he said that he got around that by training his aracari to only go in the shower, where his jet-sprayed effluvia could be more easily washed away.
They are highly intelligent and learn quickly, but they don't speak.
And as for care, his opinion was that an aracari's requirements are not very much different from those of an eclectus, save for the need to monitor their iron-intake and that dried or canned fruits are not even an option. Everything must be fresh. (Which is pretty much what I do with Bixby, anyhow.)
They also cost far less than, say, a toco toucan. The prices I'd heard for those hovered around the $17,000 range, whereas the aracari was more around $4,000 or so. (Still high for me, though not inconceivably so like the toco.)
And one other thing I learned while researching them on my own: toucans cannot use concrete or sandpaper covered perches. Their foot pads are far more sensitive and those rough surfaces will badly abrade their tender little feet.
And there is everything I know about toucans. I too wish there were some toucan owners on this forum. If only so I might enjoy those sweet birds vicariously! Lol
