Consider adding a statement mantel that stands out either through its unique design or by incorporating eye-catching decor. Choose bold colors or patterns for the mantel to create contrast against the surrounding wall. Another way to make the fireplace pop is by using accent lighting. Install recessed or track lighting above the fireplace to draw attention and highlight its architectural features. Additionally, consider adding a decorative fire screen or a large piece of artwork above the mantel to add visual interest and create a captivating focal point.
