Well, we settled on mounting the center of the fixture (the round part that mounts to the wall over the electrical box) at 63", which then puts the very top of the fixture at 70" and the center of the light source at around 67". I sure hope I made the right decision. The contractor/designer's suggestion was 5" taller than the 63". That just seemed too high for me. The electrician has set the electrical boxes and the piping for the wiring, but I'm still second guessing myself. Yikes!!!

Geez Louise, I'm back nearly 3 months later, still pondering this--yikes. Until now, I'd planned to cover most of the vanity wall in a plain wall mirror. But now that my GC covered the entire wall (!) in Porcelanosa Madagascar Blanco tile, I almost hate to cover it up! So now thinking of doing a pared-down single mirror or a pair of mirrors (something I was not keen on previously). But proportion seems a foreign language to me. I cannot figure out what size or shape mirror would look right in this space. Help? FWIW, the floating vanity (which will have clear-coated walnut drawer fronts) is 56" wide and is mounted 36" above floor. The Porcelanosa tile tops out at 7 feet and there's a sloped ceiling above. That giant light switch box is even more annoying in person, yeesh.

Water under the bridge, but for the least glare and best effect the light bulb should be at 68 inches above the floor....aka Alexa Hampton....

How about a nice classic pivot mirror. I had Minka Lavery ones installed by hubby when I had my small bathrooms remodeled. I also purchased all my lighting from schoolhouse.com. Check out their website❣️They have great high quality lights and they are handmade in America at their Portland Oregon factory. I love classic understated lights. I chose a vintage looking ceramic “Norfolk Sconce” over my mirror that was pressed,cut, and glazed by hand. For the ceiling I chose an “Otis” surface mount in polished nickel that is heavy gauge solid American brass and hand finished in their patina shop. The shades are opal glass. My electrician was quite impressed with their quality too. Schoolhouse.com has lots of vintage, modern ,and classic inspired lighting as well as other items. I am thrilled they are made in America and hubby and I made it our mission to purchase items “made in America”, when possible, when we renovated our home. Best of luck in your renovation journey ❣️
