I've also just remodeled my bathroom and want to do something different. We used to have carpet around the tub and up the one step to the tub. We've taken that out but because we have a tub which needs to be enclosed we put mahogany trim of various widths and depths around the side and both ends and painted it a deep plum to match the vanity. While I haven't started it yet my plan it so put a faux finish on the top which gives the look of marble. I've done many faux finishes and creating ones own design is very gratifying. Good luck with your project and perhaps you might use my idea.
