Houzz is the perfect place to search using the search bar above for images that feature things like that.

If you pull off the mosaics think about trying to get a subway style tile that matches your wall tiles. Update the vanity with gloss doors and more modern handles and have a wider vanity with either an undermounted sink or above mounted sink (undermounted will give you a cleaner eyeline and easier cleaning) and caesarstone benchtop is a great material to use - it's dead easy to clean. I'd keep the colours light matching your tiles and bring colour in with towels and items such as soap holders etc which are easy and cheap to change. While your at it, have all the grout professionally steam cleaned and if required re-grout (and don't forget to seal the grout - make a big difference). Get rid of the shower caddy hanging off the shower and put in glass corner shelves in the shower.

Thanks me me. The wall tiles are white and are from floor to ceiling. Should I do a darker colour vanity to add contrast as the floor will be a lighter colour too (laid in herringbone pattern).

Thanks everyone. Nik Star I did get some colour swatches for navy, but then didn't have the courage to go ahead. Think I will have to just be content with some navy towels.
