Nab New Fixtures (On Sale)
"Adding new medicine cabinets or fixtures is a great way to give a whole new look to your bathroom. For good deals on these accessories, shop at the end of May and September when many high-end retailers have inventory sales in anticipation of the new merchandise arriving."
—Jennifer Post, whose design work is the subject of a new book, Jennifer Post: Pure Space, Elegant Minimalism, by Anna Kasabian.

Consider This Modest Proposal
"A window in a bathroom is a luxury. To be able to take full advantage of the light, as well as maintain your privacy, go to a local digital print shop and get a customized static-cling window decal. You can get a monogram or a fun saying. For around $30, it's an inexpensive way to enjoy the sunlight, while staying modest. One tip: To attach the window cling, you'll need a spray bottle filled with water and one pump of liquid soap, as well as a squeegee. The soap will help manipulate the film easily."

Add an Unexpected Piece
"Including a small piece of wood furniture in your bathroom is an easy way to soften and add interest to a room that is generally dominated by ceramic tile, stone and metal finishes. We like to find charming occasional tables at flea markets and stack them with crisp white towels."
—Suzanne and Lauren McGrath, authors of Good Bones, Great Pieces (Stewart, Tabori & Chang)

Guarantee a Beautiful Morning
"The bathroom sets the tone for your day; it's where you get ready, and the way you see your appearance can affect how you feel about yourself. Choose a paint color that complements your skin tone. Light is also incredibly important. Instead of using garishly bright fluorescent bulbs in the bathroom, I rely on natural light, as well as soft and indirect lamps and sconces."
— Tim Clarke, author of Coastal Modern: Sophisticated Homes Inspired by the Ocean (Potter)

Imagine the Dreamiest Shower Curtain...

Get Hooked
"Add more hooks! A bathroom can never have too many places to hang jewelry, bathrobes and towels."
— Annie Kelly, author of Rooms to Inspire by the Sea (Rizzoli)
Pull A Switcheroo
"In small spaces, like a bathroom, a color palette change will immediately transform the space. Switching out bath linens regularly can be a fun way to introduce new patterns and colors in to your design scheme."
—Sabrina Soto, author of Sabrina Soto Home Design: A Layer by Layer Approach to Turning Your Ideas into the Home of Your Dream (Wiley)
