I agree with CF's comments. To camouflage do full wall mirrors ceiling to counter side to side and put the lighting across the top centred to each space. Consider a 2 light strip for the smaller space and a 3 light for the larger. Or 3 and 4 light whatever works with your measurements. They don't have to be the same size just the same type.

But if it's not too late and your plumbing isn't done, switch around the drawer bank and the sink in the larger space. That will make it more usable for two.

Agree that the sinks should be further apart. If possible make them equidistant from where the two vanities meet. You could fill the entire space with mirror and mount overhead sconces on the mirror over the sinks or hang pendants from the ceiling. Could do three evenly spaced pendants. One on the outside of each sink and one between the sinks.

This vanity will be in the same spot as our current vanity (thus the plumbing is already there). The old vanity that we are replacing has the sinks further apart but there is no tower on the left (and no storage). With the addition of the tower on the left, the sinks were re-positioned to the center to leave counter space on the left. The template for the counter hasn't been created. If I toss the left tower, the sinks could be positioned further apart like the are currently. I was really hoping for more storage space however. Thank you for the advice on the mirrors. It makes a lot of sense.

I think the full wall mirror is the best bet for the mirrors. You might want to consider hanging fixtures that get the light lower or mount the fixtures on the glass.

I'd love to do hanging fixtures but my ceiling is slanted. The slant goes high to that middle corner (about 9 1/2 feet), and then continues to go higher. Over the right tower, the ceiling is about 11 1/2 or 12 feet. On the left, the slant is maybe 8 1/2 to 9 feet. BTW, the total space in my bathroom is around 250 square feet. I have a skylight on the ceiling and recessed lights as well, so plenty of light. Thanks for the feedback.

What about a corner tower?

Thank you for the beautiful pictures. I'd actually thought of that but it was suggested that it might look too crowded. The total length of the left side is 71 3/4th and the right is 84 3/8th. The towers will reach 96". If I was to do a center tower, what size would you suggest (width and height)?

I would not do a left tower if I did a center tower

If you removed the left and right towers and move all the tower storage to center you could probably keep 48" and 60 " of counter space left to right or there about. Size of center storage would depend on how you execute it. Have you ordered the cabinets yet?

Oh, I just looked at your dimensions again. I was thrown by the scale of the drawing. If you stuck with the 36" and 48" countertop ratio that would give quite a bit of room for a center tower. Could install a lazy Susan for toiletries then and even do waterfall counters on the ends if the layout allows. A cabinet designer would be best to give you the actual dimensions. Of course that is assuming you haven"t ordered cabinets already. Good luck itch whatever you do.

Thank you and good to know. I have a bit of flexibility on the cabinets but they are ordered and configured. Appreciate all the insight.

One more thing. If you executed like this you get extra counter space.
