Don't let the smallest room in your house go unnoticed. A downstairs bathroom may be less than 10 feet square, but that doesn't mean you can't have fun and be adventurous with color, pattern and practicalities. Whether you prefer bold and colorful statement tiles or timeless floral prints that are pretty in a petite space, check out and click or scroll through these perfect powder room ideas that will put a stamp on the pocket-sized space. 

This closet under the stairs has been cleverly turned into a dinky power room that maximizes space. Gray and white tiles create a smart two-tone effect that increases the sense of space. A tiny sink with a black faucet slots neatly into the corner, while a picture ledge above the toilet offers 'out of the way' slim storage for toiletries. 

The wave-patterned wallpaper completes the breezy theme. It’s called Sprigs on Ocean​ and gives the tiny washroom a California-cool vibe. Painted aqua-toned woodwork continues the freshness while a dark floor anchors the space. 

Installing paneling to a downstairs bathroom adds interest and style to a small room with boxed-in features. Continue the traditional vibe with rich color and nostalgic flooring. White fixtures and a gray chevron backsplash will balance out the dark tones and echo the herringbone pattern on the floor. 

Complete the tasteful, charming look with brass fixtures and a pair of light sconces on either side of a circular mirror. The wall-mounted items are perfect for a small and traditional space that harmonizes the period decorating scheme perfectly. 

Cate Holcombe chose fun and colorful wallpaper with a white background to decorate her tiny bathroom, coordinating with the white sink and toilet. A deep inky blue on the ceiling picks out the wallpaper tone and makes a unique and interesting feature. 

A sink skirt with discreetly concealed magnets hides away a wire storage rack, while above an incredible mirror made from vintage cobblers' shoe molds adds a touch of artisanal texture and character to the jazzy little nook. Where else could you hang a mirror so unique!?

Double the use of your downstairs bathroom by adding a practical utility area. A wall-mounted shelving combination will organize your laundry set-up. Two striped green shower curtains that look smart and fresh will hide the mini washroom when not in use, turning it back into a toilet.

Plan the small space perfectly with plenty of innovative solutions. Install a worktop over the washer-dryer to create a folding area. Make sure there is space to slot in a foldable drying rack when not in use. Then use slim open shelves to keep laundry products and colorful towels tidy and to hand. 

Land of Laurel added lashings of light and storage to their tiny half-bathroom. Shiplap walls have been painted a powdery shell pink, while a grey marble mesh mosaic floor tile adds character. The tiny ceramic sink has been jazzed up with a black traditional-style faucet, while the chrome bath accessories add further chic. 

The main feature of this pale but pretty powder room has to be the layers of open shelving, color-matched to the pink backdrop and mounted above the toilet. The four shelves have been styled to the max with everything you could need to freshen up, finished with plenty of pretty green house plants that offset the monotone color.  

Glossy navy blue tiles will smarten up your powder room with an on-trend vibe. These Pickett beveled tiles add art-deco texture, while gray animal print wallpaper makes a quirky addition to the small space. A trailing plant adds to the exotic style. 

A mounted shelf slotted between narrow walls breaks up block color and makes use of the small space. The white mounted circular basin and gold faucets add to the coordinated kitsch. 

Emerald green arches highlight the windows that are then echoed and enhanced by a cleverly chosen lozenge-shaped mirror.  Exotic artwork adds interest with perfectly matched tones, while a gold shelf adds a touch of luxe charm. 

For her fifth One Room Challenge, The House That Will designed a pretty downstairs bathroom around a beautiful floral wallpaper. Norma says  "Our loo is a small room, so I didn't want to overwhelm the space with too much busyness. For that reason, I decided to let the wallpaper be the main feature and let everything else play a quieter role. So all the woodwork was painted the same warm gray color in an eggshell finish, including the new sink cabinet."

Beaded paneling in soft gray balances the floral print and ties in with a traditional small sink. A gold mirror fits in the space above perfectly and adds a touch of opulence to the classic, timeless scheme. 

A small downstairs bathroom can make an ideal shower room if you don't already have one upstairs. Reinvent a downstairs closet or erect a partition wall that creates an enclosure. Narrow furniture will slot into the leftover space neatly. Classic white tiles with grid pattern black grout will maximize the modern space. 

Clever storage will remove toiletries and towels from the floor, which helps keep small rooms tidy. Go for furniture with added hooks and use soap dishes and shower storage with suction cups. Turn the unused space behind the toilet into storage with open shelves that fit over the cistern. 

Create a moody and atmospheric downstairs toilet like The House At The Junction. Cole & Son Palm and Jungle wallpaper will transform the tiny toilet into a dark and mysterious night-time forest. A contemporary boxed-in toilet with rich wood continues the organic theme. 

Slim jade tiles tie into the wallpaper tone to create an elegant splash-back. Note there are two mirrors in this tiny space; mirrored storage behind the toilet and an antique wood framed mirror. This increases the sense of space and reflects as much light as possible in the dark scheme. 

Colorful geometric tiles make a striking feature-wall backsplash in a narrow powder room. We love this pick 'n' mix tiled wall with an angular pattern in orange and cream colors. Paint the door with a marmalade tone and introduce lush greenery into the mix. 

Tanya, creator of Dans Le Lakehouse, wanted to create a turquoise and copper powder room that glowed. A built-in vanity melts into the soft aqua-painted space, while the rose gold hammered nickel sink, circular mirror and bubble effect light create an incredible metallic display that makes the room.

Instagram influencer Hayley Stuart transformed her monochrome downstairs bathroom into a colorful bohemian-style space using a combination of Graham & Brown green paints and vinyl tile-effect floor stickers. A glorious antique storage cabinet has been beautifully restored and upcycled with coral pink paint and used to display lush contemporary house plants in bold and striking pots. 

Make the most of the small space by inserting a wall-hung vanity with a cleverly hidden storage drawer. Then continue the feature tiles to the floor – the extended vertical lines will add an optical illusion of higher ceilings in the pocket-size powder room. Black matching door furniture, fixtures and bathroom accessories look contemporary and coherent.
