My standard advice is a powder room is a place where you can go wild with design. They are usually small spaces. So, that makes them a little easier to deal with and a cool design can be even more impactful in a small space.

If replacing mirror to improve the room visually, it’s an opportune time to consider pulling the room together. Wallpaper will do that, but if not interested, suggest painting a deeper color for more interest/impact and be sure accessories are balanced and connected.

This mirror’s shape and finish would work well.

Here’s the outcome of darker walls + balance + a connection.

Pictures should be hung on the low side (a bit lower than the above).

Thank you Maureen. I love the shape and color of the first mirror. Do you know where I can purchase? I will definitely move the picture

The site did not provide any sourcing info. Try searching Pinterest for arched brushed silver bathroom mirror. I found this one fairly quickly. If you are in the US it would be less expensive on its site, if interested and you may see lots of others.

Also a google image search will turn up lots of options

Thank you both!

I kind of like the idea of a black framed mirror there, narrow frame.

Look for mirrors in thrift shops.
