Good value for the money.
Color: Ivory
This is a very good quality set. The plastic is sturdy and the colors are nice. The soap dispenser has a good capacity and shouldn't need refilling very often. The wastebasket is smaller than the one I was using which was rated as a 4 gallon size. I would say this one is about half that. The toilet brush was in 3 parts and was easy to screw together. Since I don't use bar soap, I popped out the drain insert from the soap dish and used the base to put the dispenser in. That will keep it from dripping soap on my counter. All in all, good value for money and I will buy a second set.

Nice but incomplete

I think the color and overall look for the bathroom is beautiful. I'm very disappointed that some parts were missing from the package!
