Hello,
Tackiness shouldn’t be a consideration in your plan. If raising the vanity height is going to be more comfortable for you, then I say go for it. You may have to purchase longer supply lines and a new drainpipe, which is relatively inexpensive ($25.00). As for the new 4” space you have created you can either tile that area with matching floor tile or purchase rubber molding in the same color as the tile, vanity or paint in the room. The rubber molding is the material they use in some kitchens or offices. It comes in a roll and is either self-adhering or you may have to use contact cement. This is a quick and easy fix, just don’t raise it to high, the average vanity with counter top height is about 34” from the floor.
