While the ladder may look nice, I think it may be a little too bulky for your space. It looks like it may partially block a sink in your double vanity, which isn’t very practical. You may want to consider lower profile ladder style towel racks. The floating shelves above the toilet is a great idea! The color in your example photo would tie in great with your vanity and incorporate warm tones into other portions of your bathroom. I have included a couple ideas of low profile ladder style towel racks below. Good luck!

Thank you
