Floating shelves are easy to install and come in various sizes and materials. To create a cohesive look, consider matching the shelf color to your wall paint or opting for a contrasting shade for a bold statement.

For a more rustic or industrial feel, you can even make your own floating shelves using reclaimed wood or metal pipes. This DIY project allows you to customize the size and style to perfectly fit your bathroom's dimensions and aesthetic.

Wall-Mounted Cabinets

Toilet Top Shelves

One often overlooked space is the area above the toilet. Installing a simple shelf or cabinet above the toilet tank can provide valuable storage for toilet paper, towels, or decorative items, while also adding a decorative touch to an otherwise plain wall.

For a DIY option, you can build a custom toilet top cabinet using plywood and basic joinery techniques. Paint or stain it to match your bathroom's color scheme, and don't forget to add a backsplash for a polished look.

In-Shower Storage

Another underutilized space is the area inside your shower. Installing a shower caddy or building your own in-shower shelves can help keep your shower essentials organized and within reach.

To create a DIY in-shower storage solution, you can use waterproof materials like plastic or resin to build shelves that attach to the shower walls. Alternatively, you can install a tension rod and hang a waterproof caddy or basket for a quick and easy solution.

Multi-Functional Furniture

Opting for multi-functional furniture pieces can help you make the most of your small bathroom space while keeping it stylish and organized.

By choosing furniture that serves more than one purpose, you can create a clutter-free, efficient bathroom that works hard for you.

Storage Ottoman

A storage ottoman is an excellent addition to any small bathroom. Not only does it provide extra seating, but it also offers hidden storage for towels, toiletries, or other bathroom essentials.

To create a DIY storage ottoman, you can use a large plastic storage bin as the base and build a wooden frame around it. Upholster the top with a water-resistant fabric, and add casters for easy mobility. For a more polished look, you can also build a custom lid with hinges and a latch.

Shelf-Top Vanity

A shelf-top vanity is a great way to save space and create a stylish focal point in your small bathroom. By mounting a shelf above a sink and adding a faucet, you can create a functional vanity that takes up minimal floor space.

To build your own shelf-top vanity, you can use a wooden shelf and attach it to the wall above your sink. Install a vessel sink and a wall-mounted faucet, and don't forget to add a backsplash for a polished look. For added storage, you can also install a cabinet or drawer underneath the shelf.

With these ingenious DIY bathroom storage ideas, you can transform your small bathroom into a clutter-free, organized haven that's both functional and stylish. So, grab your tools and get creative – your dream bathroom is just a DIY project away!
