Here's another picture, from a concrete sink/countertop site that we've been mousing around in, getting ideas for concrete sinks. (I have no connection with the company; we live on the other coast. We found this site when searching for info about concrete sinks on GW!) From GardenWeb Photos Here is a link that might be useful: Here's a link to the concrete site

3 lights [total of 6] look nice over 1 large mirror. 19.7 x 3.5 x 4.3 inches https://www.amazon.com/dp/B081YVS5KW/ref=sspa_dk_detail_1?pd_rd_i=B07T62FTHQ&pd_rd_w=jivH0&pf_rd_p=cbc856ed-1371-4f23-b89d-d3fb30edf66d&pd_rd_wg=Bfk0H&pf_rd_r=WWEDZHE85J50VQJ78X3Y&pd_rd_r=be7787a9-e79d-495f-b431-2dddb0f32d0a&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFOWjhIUzY0SU9UUjgmZW5jcnlwdGVkSWQ9QTA1NzE1NDExVzdQRlFMMTRDTkFWJmVuY3J5cHRlZEFkSWQ9QTAzMzk0MzMxSllSU01XS1kzUlREJndpZGdldE5hbWU9c3BfZGV0YWlsX3RoZW1hdGljJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ&th=1

How are you lighting the space? I would do a recessed light in the middle of the space, one in the shower and one in the toilet area. Then do 2 linear sconces on either side of a framed mirror or 2 sconces placed on/through a wall-to-wall mirror.

Well, I am trying to make similar decisions on this myself. I too had come across that it is better to have sink lighting from the side rather than above but have found the layout to be challenging and busy. So, I checked houses for sale with 2500 - 3500 square feet and none of them had side sconces around their mirrors. And only one or two had frames around their bathroom mirrors. Most of them had one large mirror across the sink area with lights over it. A bathroom can be a busy area, so from a minimalist standpoint, no frame. Now a mirror in the Livingroom really needs a frame.
