Cheap plastic, Stains
Color: White, Color: White
Cheap plastic holds the soap. The pump is also cheap plastic. The fake marble stains easily. Water builds up in the bottom and causes a stench so you have to wash it everyday. Not worth it, keep looking.

Great product except….
Color: White
Love the base of the holder and color! Plus the brush was a nice add-on. The soap dispenser was not as solidly made as rest of product. Had it for 3 weeks hoping dispenser will last. Would give all high praise if they beefed up the dispenser.
