This project was built and designed by Sam Macy. It’s a compact triangular bathroom shelf that fits neatly into tight corners, especially above a toilet, where space is often limited.

The design is simple and modern, with angled sides that create a clean, geometric appearance. It’s built to hold small items like face towels, candles, or decorative pieces.

Choosing Materials

Sam starts the project by selecting leftover pine boards, a lightweight and easy-to-work material for this kind of build. Using scrap wood adds a cost-effective element without compromising the look or function of the final piece.

The wood is first flattened and trimmed to size before cutting begins. Taking the time to properly prepare the boards ensures tighter joints and a better overall fit.

Cutting Angles for the Frame

The defining feature of this shelf is its triangular shape, which requires angled cuts for all connecting pieces. Sam cuts the lower shelves at a 65-degree angle and the top shelf at 50 degrees to achieve the desired geometry.

Setting up the table saw to handle these angles takes some patience. Accurate measurements are essential to make sure all three sides line up properly when assembled.

Assembling the Shelf

To join the angled pieces, Sam uses a method involving painter’s tape instead of clamps. This taping technique makes it easier to hold everything in position while the glue sets.

Once the taped-up frame is aligned and stable, Sam applies epoxy to fill any gaps and smooth out the seams. The epoxy not only strengthens the joints but also helps create a clean, finished look.

Sanding and Finishing

After the glue and epoxy have dried, the shelf is sanded thoroughly. This removes any rough edges and preps the surface for a finish.

Sam finishes the wood with a protective coat that enhances the natural color of the pine. Whether using stain, oil, or clear finish, the goal is to preserve the wood and give it a polished, durable surface.

Final Result

The completed shelf is sleek and highly functional, offering just enough storage without taking up extra floor or counter space. It’s mounted securely in the bathroom, where it serves both decorative and practical purposes.

Sam built it in response to a request from Alley, who needed a stylish storage option for their space. The result is a project that adds value while keeping the design clean and simple.
