Hi Jessie, here's one idea that might inspire you https://www.home-dzine.co.za/bathroom/bathroom-cabmakeover.htm
Jessie, Put a skirt around the inside, with double face tape. Aloha!
My name is Linda. Here's a detailed tutorial showing how to make a traditional sink skirt. (and what NOT to do. ;) ) I hope this helps you.
Oh my goodness. Thanks guys. I'm not crafty at all. I never thought of any of this. Lol. Be ready for many questions!!
Although the 'skirt' around the pedestal looks fancy, to have it on a sink that is used more often than the odd time just for guests, in my opinion, is very impractical. It would be very hard to keep it clean and sanitized.
Cabinets that are designed to go around pedestals can be purchased. Not only do they hide the post, they enable this space to be used more efficiently.
