The combination of red and black is one of the most dramatic and sophisticated color combinations, perfect for creating an elegant and memorable bathroom. However, it's important to make sure you carefully balance the two colors to avoid an overwhelming or tiring space.

Here are a few things to keep in mind when designing a bathroom in red and black:

Choose a dominant color and use it on the walls, floor, or furniture. Use the other color as an accent on decorative elements, towels, faucets, or accessories. A general rule is to use 60% of the dominant color, 30% of the secondary color, and 10% accents.

Lighting:

A well-lit bathroom is essential to avoid the space looking dark and tiring. Use natural light from windows if possible. Integrate artificial light from multiple sources: recessed lights, sconces, mirror lights.

Materials:

Choose materials that reflect light and add texture to the space. Use glossy tiles for walls, porcelain stoneware for the floor, and glass for shower enclosures. You can integrate accents of wood, natural stone, or metal to create an elegant contrast.

Style:
