Buddhists do not worship the Buddha, what we follow is the ideals and teachings put forth by Siddartha Gautama, who became a Buddha. Buddha is a title not a name, anyone can become a Buddha.
First off, the laughing Buddha is not The Buddha, Siddhartha Gautama. He is a Chinese monk called HoTei. He is a representation of a Buddha of abundance. The historical Hotei died many centuries ago but many Chan Buddhists revere him. So as far as where to place him, put him someplace where you would want a holy person to be, therefore not in a bathroom, or bedroom. In an entrance way (foyer) or living room would be best, or looking over a nice garden.
in the car or your bedroom
