The choice of finish for bathroom fixtures depends on personal preference and the overall style and design of the bathroom. However, there are several popular finishes that are commonly used in bathrooms. Here are some of the best finishes for bathroom fixtures:

1. Chrome: Chrome is a classic and versatile finish that complements various bathroom styles. It has a shiny and reflective surface that is easy to clean and maintain. Chrome fixtures are widely available and can match well with both modern and traditional bathroom designs.
2. Brushed Nickel: Brushed nickel offers a slightly warmer and more muted appearance compared to chrome. It has a satin-like finish with subtle brushed lines, which can help hide fingerprints and water spots. Brushed nickel is a popular choice for contemporary and transitional bathroom styles.
3. Oil-Rubbed Bronze: Oil-rubbed bronze has a dark, rich brown finish with hints of copper showing through. It creates a more traditional or rustic look in the bathroom. The finish is achieved by treating the bronze with a chemical solution, giving it an aged or antique appearance. It pairs well with earth tones and natural materials.
4. Matte Black: Matte black has gained popularity in recent years as a modern and sophisticated finish. It offers a sleek and minimalist look, and it can create a bold contrast against light-colored walls or tiles. Matte black fixtures can work well in contemporary and industrial-style bathrooms.
5. Polished Brass: Polished brass is a classic finish that adds a touch of elegance and luxury to a bathroom. It has a bright and shiny appearance that stands out. Polished brass works best in traditional or vintage-style bathrooms, and it pairs well with warm color schemes.

Remember, when choosing a finish, consider the overall aesthetic of your bathroom and try to select a finish that complements the other elements, such as faucets, showerheads, towel bars, and cabinet hardware, for a cohesive and harmonious look.
