I would continue with same Quartz on counter tops and white trim

Here’s a slab. Will go from 2 to 3 slabs because of this dilemma. This would not only mean an extra $2000.00 but the wait time in hurricane destroyed Beaumont Tx will be long unless we can come up with another plan

I had this happen as well but mine was because of a freak snow storm that stalled the window install until after the counter templating (they were 3 hours away so it would have pushed back counters by a month). I ended up using painted poplar as the sill after the counters went in. It has always annoyed me.

Only you know if it is worth the money and the wait. It will look good with wood sills but fabulous with the counter extending into the sill. But $2000 is a lot of money or an upgrade to an appliance.

Bite the bullet and do it as planned. You will always regret settling for something else. It's a key feature of the whole design, and you can't go off plan at this point. It's $5.50 a day for a year. Cut back on lunches out if you have to!

I think you'll have to go for the extra slab, anything else is gonna miss. Beautiful slab. Make sure they template everything going longways and pattern match.

It would look best if the counter went all the way butting up to the bottom of the window frame. Compare these pics. The one where the counter is a continuous flow into the window frame looks so much better. Also, there should be no seam in the counter if you do it with the continuous flow.

I would go with the option of wood sills, the same thickness as the slab, but instead of painting it white I would match the paint color to the slab and caulk the seam between them. That way, it would have the appearance of the slab going into the sill.

Are they able to do it without seams?? If there needs to be some sort of seams there then I would get some beautiful pieces of walnut counter and put them in there....

There will be a single seam mid sink

You will regret not running the quartz to the windows, I promise. Money comes and goes; you're going to look at this every single morning so you've got to get it right the first time.

UPDATE!!!! A language barrier between me and the installer made my decision...they made and installed it to the windows, and it’s totally amazing as you can see. Thanks for all the advice here!

Looks great. What a nice color combo and I see no reason why not to go the route that you did go. She is coming together nicely.
