5. Wood Countertop
Pair real wood in the bath with an undermount sink, as seen here, and a water-resistant urethane, acrylic, or tung-oil finish. Better yet, around a frequent-use basin, use a wood-look laminate. Continue either material up the wall as a cool take on a classic washbasin stand.
Try Formica in Auburn Maple, from about $14 per square foot, installed.
6. Tiled Baseboard
Forgo traditional molding and extend tile several inches up the wall to create an eye-catching border, like this basketweave.

8. Standout Ledge
Cap subway-tile wainscot with a DIY decorative rail. The how-to: Top upside-down one-piece baseboard with rounded window-stool trim; add cove molding where the two meet.
9. Marble Hex Tile
Add a luxurious feel underfoot with mesh-backed marble tile featuring impressive 3-inch hexagons.

12. Wood Shelves
Top an oft-ignored storage area—directly above the toilet—with shelves that are a cinch to DIY. Cut pine boards to size and stain them, and support with 1-inch cleats at both ends.

Minwax Gel Stain in Hickory, about $18 per quart; at home centers
13. Tie it All Together: Library Light
Install a sconce with an articulated arm above the medicine cabinet for a style boost. It's just as great at providing effective task lighting in the bath as it is at illuminating bookshelves.

14. Double-Duty Fabric
Take a cue from designer spaces and match the material of your shade to your shower curtain. Lightweight cotton won't block light and is easy to launder. Just be sure to hang a waterproof liner behind the shower curtain.

15. DIY Sink Stand
Build a simple table like this one by mounting an edge-glued panel over 2×2 legs reinforced with corner braces. Finish with a cheery, coordinating shade of paint. Install a drop-in basin or a statement-making vessel sink, like this one—just plan the stand's height accordingly.

Similar to shown: Newbury Cart, starting at about $269; Restoration Hardware
17. Surprising Storage: Customized Pails
Galvanized-steel buckets can do more than hold gardening tools or ice-cold drinks. Personalized with paint, they are the perfect catchall for kids' bath gear.
Similar to shown: Behrens 12-quart bucket, about $10; Lowe's
18. Surprising Storage: Towel Tree
A problem-solver in the entryway, a coatrack can be a helpful addition to the bath for hanging wet towels. One with integrated storage is even handier—here, the umbrella stand holds a fresh supply down below.
For a similar solution, try a storage tower with shelves and hooks: three-tier tower shoe and coat rack, about $112; Overstock
19. Surprising Storage: Vintage Dresser
A treasure found in Grandma's attic (or on Craigslist) can be an unexpected and elegant addition to the bath. Take this highboy: Deep drawers offer ample linen storage, while delicate legs keep the piece from feeling too heavy and overwhelming the room.
