What’s wrong with the vanity? Have you thought about painting it white? A white mirror frame would be a nice update. Some new decor would help. A basket of white flowers. Do you have room underneath for all the stuff on the countertop? If not, putting everything in baskets would help tidy up.

Yes, is vanity in good condition? some have had success with chalk paint - around water, probably the second layer, maybe wax but idk. A pretty and muted color that you use in rest of house?

Hang a larger piece of art where you have the penguin, something to complement the beige tile. Like this:

This one's $60:

I prefer paint to wallpaper in a bathroom with all that moisture. I think a tub enclosure would be so much better than the shower curtain.

Pale Oak paint... 30x39" Maybe too much with ruffled curtain, but I like it!

Thanks for all the great suggestions. I am replacing the vanity - it's broken and can't be repaired. Was considering a graphite gray to pop the gray in the edge tiles thoughts?. But, I love the idea of framing the mirror would you do that in a color to match the vanity?

Considered a shower enclosure but didn't know you could do that 'after the fact'...good suggestion. Any thoughts on better storage for the shower as there is no niche? There is a shelf under the window, but it's full of mold so we're ripping that out.

Love some of the lighting suggestions - but need to have something wider on the mirror as it's a double vanity of 72" so lighting would need to be at least a 60" fixture widthwise.

OP, you sort of casually mentioned, “There is a shelf under the window, but it's full of mold so we're ripping that out. “ but your original question made no mention of that. Perhaps you might need to do more than cosmetic work in that bathroom.

That tile gives you so many ways to go. Blue can even work. I would go with a vanity with the most drawers you can get, some of them deep drawers so that maybe that stuff left out on the counter will get put away. If you can get the largest light you can find to brighten, that can help a lot. You can even look for a light with a matching ceiling fixture and change them both out. Look for ones with LED bulbs and as bright as you can find. LEDs will save you money in electricity forever.

Look for an enclosure door with no track, if you can. I have tossed enclosures out of every house I have ever bought because of them. They get dirty, plus you cannot sit on the side of the tub with a track on it. That is especially important if you might still have children and this is the family bathroom.

@Bluebird, it's only moldy in the window because they used wood framing instead of vinyl. That is being replaced.
