Looking to add some chic and practical storage to your home? You've come to the right place! Creating your own floating shelves is a fantastic DIY project that not only enhances your space but also saves you money. This guide will walk you through the process, focusing on affordability and transparency, so you can achieve that sought-after minimalist look without breaking the bank.

This DIY guide will show you how to build stylish and cost-effective floating shelves using readily available materials in South Africa, providing a clear breakdown of potential expenses and a step-by-step process.

‍

What You'll Need:

Here's a breakdown of the materials and tools you'll need, along with estimated cost ranges based on current South African market prices (as of June 2025). Prices can vary based on brand, size, and promotions at different retailers like Builders, Leroy Merlin, or local hardware stores.

Materials:

• Pine or Plywood Board:
  • Pine: Often the most budget-friendly option. A standard length (e.g., 3.6m to 6.6m of 38mm x 228mm untreated SA Pine) can range from around R180 to R650, depending on the dimensions. For a single shelf, you'll only need a portion of this, making it even more cost-effective.
  • Plywood: Generally more expensive than pine. A full sheet (e.g., 18mm x 2440mm x 1220mm untreated pine plywood shutter board) can cost between R450 and R850. If you only need a small piece, look for offcuts or ask the store to cut it to size, which might incur a small fee or even be free.
• Wood Screws and Wall Plugs: A pack of wood screws and wall plugs suitable for brick or concrete walls (common in SA) will likely cost between R15 and R50, depending on the size and quantity.
• L-brackets or Concealed Shelf Supports:
  • L-brackets: These are generally more affordable, ranging from R5 to R40 per bracket, depending on size and material (e.g., small corner braces can be as low as R3.50, while larger metal angle brackets can be R35 or more). You'll typically need two per shelf.
  • Concealed Shelf Supports: These give the true "floating" look but are usually more expensive. You can find them ranging from R15 to R25 per support, depending on the size (e.g., 10mm x 100mm or 14mm x 140mm). You'll usually need two per shelf.
• Sandpaper: A few sheets of sandpaper (various grits like 80-grit, 120-grit, 180-grit) can cost around R5 to R35 per sheet, or you can buy a multi-pack.
• Wood Stain or Paint (optional):
  • Wood Stain: Smaller tins (e.g., 50ml to 500ml) can range from R40 to R200, depending on the brand and colour.
  • Paint: A small can of acrylic or general-purpose paint can range from R35 to R100, depending on the size and type.
• Clear Varnish (optional, for durability): A small can can cost anywhere from R50 to R200.

Tools:

• Drill: If you don't own one, a basic corded or cordless drill can range from R500 to R1500, depending on the brand and features. You might be able to borrow one from a friend or neighbour to save costs.
• Screwdriver (or drill with appropriate bits): A basic screwdriver set can cost between R100 and R300. If you have a drill, you'll just need the right bit.
• Spirit Level: Essential for ensuring your shelf is straight. A good quality spirit level can cost from R30 to R350, depending on the length and brand.
• Measuring Tape: A basic measuring tape is usually around R50 to R170.
• Pencil: Very affordable, typically less than R20.
• Electric Sander (optional): If you're doing multiple shelves or want a very smooth finish, an electric sander can be a great investment, but it's not essential for a single shelf. Prices vary widely, but a basic one could be R400 and upwards.

Estimated Total Cost (excluding tools you may already own):

For one floating shelf using pine and L-brackets, your material costs could range from approximately R150 to R400, depending on the size of the wood piece you purchase and your chosen finish. If you opt for concealed supports, expect to pay a bit more for those. This estimate assumes you don't need to buy a drill or other major tools.

‍

Step 1: Choose Your Wood

Pine is a fantastic choice for budget-friendly floating shelves due to its affordability and widespread availability in South Africa. When selecting your wood, consider the dimensions of your desired shelf. Common sizes are around 600mm or 900mm wide, with a depth of about 200mm. This is usually sufficient for most display or storage needs.

A great tip for keeping costs down: many hardware stores like Builders Warehouse or Timbercity offer wood cutting services, often for a minimal fee or even free if it's a simple cut from a larger piece you're purchasing. Don't hesitate to ask if they can cut your chosen board to your exact specifications.

‍

Step 2: Sand and Finish

Once you have your wood cut to size, it's time to prepare it for its grand debut! Use sandpaper to smooth all edges and surfaces. Start with a coarser grit (like 80-grit) to tackle any rough spots or imperfections, then move to finer grits (120-grit or 180-grit) for a silky-smooth finish. This not only prevents splinters but also gives your shelf a professional, polished look.

Now for the creative part! You can choose to leave the wood bare for a natural, rustic feel, or you can add a touch of personality with wood stain or paint. Wood stain will enhance the natural grain of the wood while adding colour, while paint will give you a solid, vibrant finish. If you choose to stain or paint, consider applying a clear varnish afterwards. This adds an extra layer of protection, making your shelf more durable and easier to clean.

Step 3: Mark and Mount Your Brackets

This is a crucial step for ensuring your shelf is level and secure. Using your spirit level, draw a straight line on the wall where you envision your shelf. Next, measure and mark the exact points where your chosen brackets or supports will be installed. Make sure they are perfectly level and evenly spaced to provide optimal support for your shelf.

For solid walls (common in South African homes), like brick or concrete, wall plugs are absolutely essential. Drill holes at your marked points, insert the appropriate wall plugs, and then screw your L-brackets firmly into place.

If you're going for that truly "floating" aesthetic, you'll use concealed shelf supports. These require drilling specific holes into the back edge of your shelf that match the supports. Once the supports are securely mounted to the wall, the shelf slides onto them, creating a seamless, bracket-free appearance. Concealed supports are widely available at most hardware stores.

‍

Step 4: Attach the Shelf

With your brackets or concealed supports securely in place, carefully position your prepared shelf on top. If you're using L-brackets, you'll likely need to secure the shelf to the brackets with screws from underneath (check your bracket type – some might have pre-drilled holes for this).

Before fully tightening everything, grab your spirit level one last time to double-check that your shelf is perfectly straight. This final adjustment ensures a professional and aesthetically pleasing result.

Step 5: Style It Up

Congratulations! Your DIY floating shelf is complete. Now comes the fun part: styling! Floating shelves are incredibly versatile and can be used to display almost anything. Showcase your favourite books, arrange an assortment of pot plants, display cherished ornaments, or create a gallery with framed photos. They also work wonderfully in kitchens for storing spices or everyday essentials, and in bathrooms for toiletries, adding a minimalist and organised touch to any space.

Budget Tips for Your Floating Shelves:

• Shop Smart: Always keep an eye out for specials and promotions at local hardware stores like Builders, Chamberlains, and Leroy Merlin. You might find great deals on wood or other materials. Don't forget to check online marketplaces like Facebook Marketplace for second-hand wood or even tools that are still in good condition.
• Embrace Offcuts: Timber yards often sell wood offcuts at significantly reduced prices. These smaller pieces are perfect for creating compact floating shelves or for testing out finishes before committing to a larger piece.
• Reuse and Recycle: Get creative with materials! Old wooden pallets, discarded shelving from old furniture, or leftover wood from other DIY projects can be repurposed into unique and characterful floating shelves. This is an excellent way to reduce waste and save money.

With a little time, effort, and creativity, you can build beautiful and functional floating shelves that perfectly complement your home's style without costing a fortune. Give it a go and enjoy the satisfaction of a personalised and practical addition to your space!

Frequently Asked Questions

How do I choose the right wood for my floating shelf if I'm on a tight budget?
‍Pine is generally the most cost-effective and readily available wood in South Africa for DIY projects. Look for untreated SA Pine at hardware stores. If you need a smaller piece, ask about offcuts, as these are often sold at a lower price. Plywood is another option, but often pricier than solid pine.

What's the difference between L-brackets and concealed shelf supports in terms of cost and appearance?
‍L-brackets are visible and typically more affordable, usually costing R5-R40 per bracket. Concealed shelf supports are hidden inside the shelf, giving a true "floating" look, but they are generally more expensive, ranging from R15-R25 per support, and require more precise drilling into the wood.

Do I really need a drill for this project, or can I get by with just a screwdriver?
‍While a screwdriver can work for very light applications or if you're pre-drilling pilot holes with a small hand drill, a proper electric drill is highly recommended, especially for drilling into walls for plugs and for driving screws efficiently. If you don't own one, consider borrowing or renting one for the day to save on purchase costs.

How much should I expect to pay for wall plugs and screws in South Africa?
‍A small pack of suitable wood screws and wall plugs will typically cost between R15 and R50, depending on the size, quantity, and brand. It's always a good idea to have a few extra on hand.

Can I paint or stain my floating shelf, and how much will that add to the cost?
‍Absolutely! Painting or staining can dramatically change the look of your shelf. A small can of wood stain (50ml-500ml) can range from R40 to R200, while a small can of general-purpose paint might cost R35-R100. A clear varnish for protection can add another R50-R200. These are optional costs, but they can significantly enhance the shelf's appearance and durability.

Is it necessary to sand the wood, or can I skip that step to save time?
‍Sanding is a crucial step! It prevents splinters, creates a smooth surface for finishing (paint or stain adheres better), and gives your shelf a much more professional and finished look. While it adds a bit of time, the result is well worth the effort.

How can I ensure my floating shelf is perfectly level?
‍A spirit level is your best friend for this! Before drilling any holes, use your spirit level to draw a perfectly straight line on the wall. Then, when marking and installing your brackets or concealed supports, continuously use the spirit level to ensure they are aligned. Double-check with the spirit level again after the shelf is attached.

What should I do if my wall is not solid (e.g., drywall)?
‍If you have drywall, you'll need to use specific drywall anchors that are designed to hold weight in hollow walls. These are different from standard wall plugs for brick/concrete. Ensure you purchase anchors rated for the weight you intend to place on your shelf. It's always best to try and locate a wall stud if possible, as screwing directly into a stud provides the strongest support.
