Although small powder room did not change in size, and the sink is still in the doorway, we replaced the sink with one that is half the depth so it is easier to enter the room.  The sink is actually a wall mount sink but we reinforced it with legs so that individuals with mobility issues can put their weight on it and use it for support.  We used the pre-drilled hole in the sink for a soap dispenser and wall mounted the faucet.
