Many of us put a slanted stiff material of some sort under the cage, that empties into a tote or a into a gutter that empties into a bucket.
We just installed Coroplast in our rabbitry. It slants forward to some vinyl gutters. The top level empties into a bucket at the end, and the bottom level empties into a pan in the middle. This replaced corrugated metal chutes with metal gutters. The caustic urine ate it up.
Some use corrugated plastic or fiberglass, one has used flexible shower wall stuff. There is no wrong way. Just keep in mind that you do need to extend out well past the sides of the cage (6-12", the more the better), or they very well could overshoot your chute.
It is probably a good idea to hang a shower curtain between the house and the hutch (maybe attached to the back of the hutch, as long as it does not touch it), in case of spraying.

I don't have any experience doing it myself, but I have heard you can train rabbits to use a litter box. Maybe someone else one here has done that before that could tell you more.
I have had rabbits use a litter box before. Possibly the best way to litter train a rabbit is to mop up some of their urine with a paper towel, and then put the towel into the litter box. Then remove all traces of urine anywhere outside of the box. This may have to be repeated, but they usually pick it up quickly.
You cannot use clay litter (either clumping or non-clumping) in a rabbit litter box. There is a high probability of GI blockage from the rabbit ingesting the clay. Various things can be used, including pine (not cedar) shavings, wood pellets, and compressed paper litter.
I tried all three of those myself. My favorite was the wood pellets. They can be bought as Feline Pine cat litter, but they will be much cheaper to by as Stall-Dri (for horses) or as wood stove pellets (make sure they have no additives).
The wood pellets you just stir at first. The pellets will break down into a coarse powder. As the powder then gets wet, you scoop the wet stuff out, and add some more pellets.
You will still need something below the cage to catch poo balls, since the rabbit will still drop some of those outside the litter box. Or you could sweep them up.
