I have a large master ensuite with a double sink vanity that is 11.5’ or 138” wide total. i want a hugeeee single piece mirror that spans the length of yhr vanity as i want to make the space feel more spacious and airy but near impossible to find a wall mirror that size. largest i can find is 84” x 40” (placed horizontally). should i do one 84” x 40” mirror or two 60” round mirrors side by side (or even 2 60” square mirrors side by side or 2 60” x 40 ” mirrors side by side)?

thanks :)
