I have one just like it. It is an over the toilet shelving unit with the lower section removed. I purchased it at Aldi's but Walmart had something very similar. There is another shelving unit that fits over the stove that I have seen somewhere in this forum which I also have and it is much sturdier and the shelves are adjustable.It is 30 inches tall and 24 wide. It is sold by Home Depot for ~ $20. About the same price for over the toilet unit.
