Help with color to bathroom!!

select a light blue hue of a color

Depending on the shade of blue... I'd go with ocean/beach or medow/sky colours. In my own bathroom we opted for a rich sunset colours: orange and a lavender-pink. Looks WAY better than it sounds.

They have some really pretty gray paint colors out now. Would go well with the blue. I would paint cabinet and trim white and put a white frame around the mirror. You can easily frame the mirror with molding and a good glue and glue it right to the mirror. You will end up with a bright room.

I like seafoam then use a sponge and top off with scattered glaze.

Take out anything with dark wood, picture frames, towel bars, etc. Paint the cabinets with enamel paint, after thorough prep job, using a color lighter than the floor but in the same color family. Put in chrome towel bars to match faucets and bounce light around. Frame out your mirror with painted wood to match cabinets or even lighter color...could match the blue you mentioned. Put up hand towel bar and buy hand towels to get rid of paper towels and save a tree. A pale pale blue wall or bluish white on the walls...be careful and put up swatches to pick the correct color. Chrome or silver cabinet hardware to tie into your towel bars. If you have any wall that could be an accent wall (can't tell because of your limited photos) add a wall paper with cream, pale blue, and at least a third color. Pick towels and bath mats to complement your new brighter room. Oh, no amber lamp shades, only white or clear, wash the glass and wash bulbs (I do mine in the dishwasher) and switch to warm LED bulbs in a higher wattage and less electricity use.

I think you're off to a good start. First and foremost, upgrade your lighting. Then put a frame around the mirror - use a blue/grey - and put one large piece on the wall. If budget allows, put a cabinet in between the sinks to hold the paper towels, etc. Good luck.

Soft gray or yellow or bright white would brighten the room. You could decorate with a beach theme and add an extra mirror, painted wood trim and the inside door, and/or bright curtains and a shower curtain. Document it all to share on Facebook. ☺️

Thank all of you so much! I have a good start.
