Designing Kitchens and Bathrooms - Bathroom Molding: before or after vanity

I've just stripped my son's bathroom of pink roses wallpaper and awful tan vinyl floor. I've repainted the walls blue and put down ceramic tile. I'm getting ready to put a new vanity and toilet in very soon. However, i need to install baseboards at some point as well. Can I install the vanity and then put the baseboards down? That would save from putting down baseboards that won't be seen behind the vanity, right?

Do I have to have baseboards behind the vanity?

Baseboards aren't used behind cabinets. Install the vanity and the base before you install the commode.

that's what i needed to know!

Should i paint the baseboards before i put them down or after? Should I butt the baseboard next to the vanity or should it be a mitered (angled) cut?

Butt the base up to the cabinet. It's your call whether or not to prepaint. If you prime and apply 1 coat of enamel prior to installation it might save you some time. It will need a final coat of enamel after installation, caulking and puttying nail holes.
