Design a spacious and inviting full bathroom in French Mid-Century Modern style. Start with a warm color palette featuring soft whites, warm wood tones, and touches of brass or gold. Choose a double vanity with clean lines, polished wood finishes, and marble countertops. Install a large, frameless mirror above the vanity to create a sense of openness. Opt for a walk-in shower with sleek glass doors and geometric patterned tiles, complemented by brass fixtures. Add a freestanding bathtub with a minimalist design for a touch of luxury.
