Design Element vanities are freestanding and require no additional instillation or mounting to walls. Vanity hardware is attached to the doors and drawers. The handles are changeable and can be switched out to different styles. To mount sinks and countertops we do suggest using a construction grade adhesive that is specifically for stone such as SA Loctite PL-530.  At this time, faucets and drains are not included and we do not sell backsplashes or side splashes. For more information on instillation and product refer to how to videos and spec sheets.
