Great! I love the look of that teal rug with the white. I wasn’t even thinking about the mirrors but that would be an easy update as well! Thank you for your input!

Is there a colour you would go with for the trim? I will be repainting all the trim as well.

Use the same paint as the walls on the trim, only use a different sheen for the trim (semi gloss)

You are lucky in that both your bathrooms are super neutral and you don't have any major uglies going on. Painting the walls a white I think would look great as long as the underlying colour in the white went with your tile. I would change the mirror above the small vanity. Looks like the existing mirror may be a medicine cabinet so I would get rid of it and go with a decorative mirror with some personality. The window in your bigger bathroom looks weird. The blind looks way too big for the window and the sill below the window also looks too big. Did the previous owners make the sill to match the size of the blind? I would replace the blinds in both bathrooms and put up some kind of blind or curtain that uses print fabric with colour just to get some interest going. I would also consider painting the vanity in the larger bathroom a colour and change the door hardware. Use one kind of knob and put in the corners of the doors (looks weird having a handle in the middle of the door) and a knob in the centre of all your drawers including the unusable centre panel (looks weird not having a knob there). Add decorative rugs to both bathrooms to get some colour in there and replace your towels with coloured ones. So, add colour to both rooms with towels, rug, blind/curtain. And by colour I mean grey or brown or an actual colour. Something with contrast and not just white or cream.

One of my favorite HIGH impact designs, is a DARK ceiling in an overall light bathroom.
