The arch over the tub with very subtle can lighting. The towel rack at the side of the tub. The sink cabinetry comes forward in a square (to save money versus the curved front cabinets, plus I like this a lot). Also the sink does not compete with the barrel vaulted ceiling.
I love the overall layout of this bathroom. The floors, faucet knobs, flowers, and light fixtures are all very elegant. I like the linen closet on the far side and the flowers by the jacuzzi. I also like how the jacuzzi is in its own little carve-out.
