If you plan to usually leave the door open to the powder room, I would have the woodwork match. If you don't, then do what makes you happy on the cabinets. As far as colors, I like ice blue in the bedroom and ecru in the powder room. That's what I've had for the last 5 years since we had to rebuild (after a fire) and I still love the colors. (Remember not to use yellow or green in the room where you will apply your make-up.)

Thanks everyone! I talked to the company and they are happy to exchange for a different one, they will send me a photo of a few different ones on Monday. Thanks so much for the advice, I feel lucky!!

as a buyer i would be looking for a spacious uncluttered looking ensuite not twin basins squeezed into a small vanity..imo the counter isn't for storage itá place to rest a glass, dryer, toothbrush or stand toiletries until they can be put away in the wall cabinet but there are so many different vanities and your favourite will be différent to others and it's quite easy to replace a vanity as long as there is enough available space...i would choose a wall hung 1200 wide vanity with a single drop in sink and only consider twin small drop in sinks with a minimum of 1500

I think you can definitely go with same width and semi-recessed since you would like to have as much cabinet space as possible. We've had lots of customers getting same length vanities and mirror cabinets before for design or storage purposes, and their results look great. I've attached below photos from their projects for your reference ;). Same length can look great especially for rectangular mirror cabinets.
