Hi All, and Happy holidays! I'm replacing an Alcatraz-style single sink in a third-floor bathroom. The existing supply lines are the old-school stiff tubes and they come right out of the floor (no shut-off valves) and are almost 36 inches from connection to connection. At the local home store the longest flexible supply lines are 24 inches. Can I get 36 inch flex lines special order? Should I re-use the rigid ones? Build up the pipes about half-way and install shut-offs there?
Thanks!

Depending on the type of 'stiff tubes' you have just cut them off at the proper height and install shut off valves.
Copper is easy to work with. However if you have galvanized piping you will need threading equipment.
 
If you just dealing with 3/8 copper it's a simple fix, make sure the water is shut off, then cut the line about 20" of less below the sink, then install a 3/8 X 3/8 straight compression shut off valve.
