Today, this is where I'd like to be, in Isaac Mizrahi's bathtub (sans Isaac Mizrahi, of course). His Manhattan home, a historic 1931 building (hence the radiator in the bathroom), was featured in Architectural Digest not too long ago. Although the rest of the home reflects his modern, colorful essence, I love the simplicity of the bathroom, the modern rigid lines and natural light. See more, here.
