You can put a tank on the floor.
I have one of my tanks on the floor of my basement with a heavy rug underneath, no problem. Only issue you may have would be the aforementioned filtration - you could probably only go with a HOB filter/UGF or sponge. Canister would most likely be out of the question due to most canisters needing to be below water level.
