Spirit is the second picture and sand dollar is the third picture bottom left. Also here’s a picture of the perimeter cabinet color.

Be careful with quatrz behind the stove, unless you have a backguard. Quartz has a high percentage of plastics and resin and will scorch badly. I would not pick backsplash tile untill everything else is installed if at all possible.

Is it too late to change your kitchen window from fixed to operable?

Sometimes you just need to air out the kitchen!

Is the range induction or gas? If gas/propane reconsider the quartz backsplash. I would use the same tile for both the sink and range walls. I also think you can find a more unique/special tile for the space.

I have white cabinets, taj mahal quartzite counters, wood floors and wood ceiling beams. I used this marble mosaic for all my backsplash, and up to the ceiling on the sink wall. I have a large kitchen with 12 ft ceilings and it definitely called for something more than subway tile.

Don't be afraid to try out different tile patterns/colors. Visit several local independently owned tile stores to see the most options. Not all shops carry the same lines. Borrow grouted sample boards to bring to your house once the cabinets and counters are installed.

No rush ... I didn't find my backsplash until we moved in and had been in the house around 5 months.

Do a lot of reading and potentially reconsider quartz as a splash behind your range if it is gas.

If is fine to narrow down tiles now, but do yourself a favor and wait until the entire kitchen and lighting, including undercabinet lighting, is installed to make decisions. Colors, lighting, reflections, and the impact of the actual space can all change how your splash tile is going to look. Now is too soon to decide.

Also, remember, what a singluar tile sample does not show you: the pattern of grout in your layout. How busy - or not - is the layout and grout color in combination with the waviness of the tile and the veining of your counter.

While I'm sure that you are looking for answers just to your question re: which tile to install on the sink wall and in the pantry. However, the information provided in the above comments about the potential for quartz to scorch is something that you need to make sure that you've researched - especially if you have a gas cooktop.

It would be nice to use a tile that has a bit more of an impact on a wall with only floating shelves.

Are you able to wait to select your backsplash tile until after your cabinets/countertop/lighting/flooring have been installed? It is best to select your tile after everything else has been completed.
