The Drake is normally a pretty big foot print. If it needs to be even bigger, you can look at the Dartmouth or Clayton.
Also the Soiree and Guinevere are even bigger. Those seem like ovekill for a rental unit though.
For petite, the Drake does come in round, which is 1-1/2" shorter then the elongated. The Promenade also comes in round.
Do you have the standard 12" rough-in, or is it something like 14"?
