Yes.  Tub rental includes the disposable liner and the cost is $85.  You will need to provide a tarp for underneath the tub and another tarp to cover the tub when not in use (to keep it warm).  You will also need a new hose that can reach from the faucet to the location of the pool.  With the rental I provide a faucet adapter and a pump for cleaning the tub after the birth.
