What does the rest of your bathroom look like? I’d do some nice wallpaper, and the rest just like you said. I’m no designer though. Depending on how far down the renovation road you want to go, perhaps consider replacing the floor tile to something more era appropriate? I think alot of bathrooms from this era had chrome (or something like it) hardware...but if you have original hardware that is brass, continue with that. I would think that the latches on the top cupboards will be an indication once you’ve got the paint off, whether the knobs etc should be brass or chrome(?) I’m not even sure whether you have to put the baking soda in...I’ve done it with and without and it’s worked both ways.

Thank you so much! I shall look at that option too! :)

BM October Mist might work in LR BM Wind's Breath may work in Bath Paint LR all 1 color or paint the top the same color as the trim

I would see what undertones the hard surfaces are first .Are they green, beige, blue etc by matching them to paint chips. That way you can pick the correct colour of wall paint and the right blue for the vanity.
