My older two boys share a room and sleep in bunk beds. Since we moved them to bunk beds it's been great as it has opened up a ton of space in their room for quiet time away from the chaos of the rest of the house. I love bunk beds.
Coastal/Cottage bathroom - I like the wood floors and the idea of a cabinet between the sinks. I love the idea of having separate shower and tub. I would rather one of the sinks be a vintage vanity for makeup/jewelry.
