To provide a faucet column support device allowing a constructer to easily perform the setting of a faucet column and the piping thereto by oneself.

A faucet column support device 1 comprises a vertical cylinder 2 having a hole part 2a for fitting the lower part of a faucet column 4 from the upper end of the vertical cylinder 2 and a piping window part 2c formed on the lower part and/or bottom part of the vertical cylinder 2, and a stably setting member 3 for setting the vertical cylinder 2 with good stability provided on the vertical cylinder 2. By using this faucet column support device 1, a feed pipe can be arranged and constructed through the piping window part 2c by oneself while the faucet column 4 is supported and raised so as not to fall by fitting the lower end of the faucet column 4 to the hole part 2a of the vertical cylinder 2 stably set by the stable setting member 3.
