We have to have a join in our vanity benchtop :(

After looking forward to a single 3m long piece of caesarsrone on our ensuite vanity... Today I was notified that there will need to be a join... Because the vanity is 10cm short of a single piece :(

Devastated!

The CS guy is suggesting we have the join on the shower side of the vanity and half way between the left basin and wall. What do you think? What to do what to dooo? :(

Would lining up the benchtop join with the grout line in the splashback  (as below) look ok? (29cm from the wall and 31cm from the basin)... or would it emphasise the join even more?
