find something you love first. it can be tike, vanity, flooring, really anything. then you can add in pieces that work to enhance what you love

I think if you've got your design idea set, then the best way to proceed is to look through bathroom ideas on Houzz and see what appeals to you. You want all your choices to work together, so if you can get an overall picture of your likes/dislikes and shop accordingly the job will be easier. If you fall in love with a tile that is more rustic, then your choice of vanity may not work if you buy it first. You also have to consider your budget. Real stone tiles tend to be much more expensive than ceramic or porcelain. Also consider the cost of demolition and new waterproofing. The basics may cost a lot more than you anticipate which may limit your budget on replacements.

Do you like a more formal look? Maybe marble tiles in the bath and floor? What type of faucets and hardware do you like?

When shopping for tile, ask the store to show you collections that have different sizes, shapes and trim pieces. Also, you could consider the same tile in different colours so that it is cohesive but the colours work together.

Sarah Richardson from HGTV is one of my favourite designers. She has many examples of bathrooms and often uses tile and combinations of tile which look fabulous IMO.

Here is a link to a pinterest page which has examples of many of her projects.

Here are some pictures to give you some ideas.

This is very calm and serene. Whites and greys, marble around the tub and on the vanity counter.

A little more colourful and less formal. Note the tile in the shower, a band run vertically amongst the rest of the horizontal. It makes such a nice difference and yet so easy.

This one is quite formal. Marble on the floor with an inlay to make it look like a rug. You'd need a skilled tiler but oh so pretty.

I don't know where you are located, but more often than not, her tile source is Saltillo Imports in Toronto Canada. Worth having a browse through their site but you'll be able to find similar choices on other sites as well.

Pick the thing you care about most first.
