the house is new. counter granite. browns
Hi ! Since your bathroom is small , and you have Brown's already in there , I would paint the walls a light color to brighten the room , which will make it look bigger . Or if your walls are already painted , try putting up photos in frames that will lighten your room . Take photos on your phone of a flower or plant up close or a shell in the sand . Then play with photos using the photo editing function , you can give the pictures some interesting looks , like sepia , will give the picture a black and white look , but with a brown , tan ,& white hue. Then go to anywhere that prints like Costco or CVS ...And blow it up , should cost under $5 , then frame it !. Use white shower curtain , white small planter with a succulent plant...
I would start with a patterned shower curtain that you love. Then choose colors from there for paint. If your changing tile or countertops keep it neutral for timelessness. :)
Pale beige or pale tans are complementary to your granite colors. A very small dose of black can add a trendy edge, if you like.
Towels and bath linens that coordinate with the lighter granite colors will add cohesion to the space.
