Above all else, your design should be practical and provide the essentials. There’s no need for elaborate waterfall showers, grand tubs, or dual vanity sinks. A 1/2 bathroom typically only contains a toilet and a sink.
There’s no space for a bathtub or shower, but feel free to include an extra-large countertop if you have the space available. A classic bathroom style usually involves beautifully contrasting colors. You’ll also need to include timeless materials like marble, stone, and ceramic.
