Hi there, did you mean to attach photos? I don't think they posted. I know this is from a while back but I'm interested to hear what you ended up choosing.

You are going to have to leave your comfort zone on this one. Walnut is "brown", you have "pink" as a counter top. I would suggest going with another version of the colours already in the room. you have gray/beige and white. I would hesitate going white...but it can be done. You can move into the grays and be very happy (it would look very modern) or you can move into a beige that holds a hint of pink in it (not pink...but a blush of warmth). Or you could go really wonky and add in something like a brushed stainless steel look to the cabinets and have it go "space age". There are specs of blue/gray in this counter top. The next think to look at is an "ashwood" or dark gray wood presentation that has some blue in it. It would lighten the space yet still add drama that dark cabinetry offers.

I wanted to use a shimmery pearl backsplash but it was problematic to install. Looking for something reflective. My island is deep blue (sea serpent by Sherwin-Williams), cabinets white with clear glass in second row uppers, fixtures, pulls and knobs all champagne bronze. Hoped to find something more exciting than white subway but I need help and fast so we can install the range hood and the stove!

the sink should be at 33" from the floor. your countertop height will depend on if you're using a top mounted or insert sink
