This three piece set is called a lavabo. The bottom bowl is made as a planter to hang on the wall. The piece with the tap is for water which allows you to water the plant without having to remove it from the wall. There is also a lid for the water well. The planter measures about 5 1/2" deep and is about 4" x 9". The water well measures about 4 1/2" deep with the spigot and 6 1/4" x 7 3/4" without the lid. The lid measures 3" deep and is 2 1/2" x 5". I believe this set was used only for decoration because it is very clean. The polished edges of the rims are free of any chips or flea bites. The hobs are all intact as well. This set appears to be in perfect condition. Please email me with any questions.
