White might seem to be a sterile color for the bathroom, but the key to working with it so it doesn't seem boring is to use different textures throughout the room. Choose a fluffy white rug for the floor and a soft flowing cotton or lace for window treatments. Hang thick and thirsty towels from towel rods, and place white candles and bars of soap around for a pleasing look. White gives rooms a crisp and airy feel, so texture will only enhance your cottage décor.
Neutral colors complement the cottage style because they are easy on the eyes, and they create a cozy mood. Neutral colors work to enhance the other colors in your room. Off-white, cream beige and tan work with many colors, giving you freedom to incorporate spots of color without overwhelming your bathroom. If you go with a neutral color on the walls, you can decorate with bright, floral prints and checks for a look that feels pulled together. Hang a floral shower curtain, and use rugs and towels with checks and stripes in the same colors.
Many cottages incorporate muted colors because they maintain the relaxed ambiance cottage owners desire. Dusty rose and pale shades of green are pleasing to a cottage palette as long as they aren't too bold. Green is known for bringing energy into rooms and will brighten rooms with small or few windows. Select sun-bleached colors when looking for the right shades. Keep the same shade throughout your bathroom. If you go with a muted color on the walls, keep that same look with window treatments and rugs. Combine colors that work with your décor, but don't mix a shiny metallic silver with a soft, muted gray.
Blue comes in many shades that enhance the cottage look. From turquoise to periwinkle to powder blue, several shades of blue add charm to cottage themes. Checks, stripes and floral prints in blue will make your bathroom feel calm and cozy. With blue colors on the walls, you're free to go with gentle white lace for a soft look.
