Exemplary embodiments of dispensers are disclosed herein. One exemplary dispenser is a soap or sanitizer dispenser. The dispenser includes a housing (102). A removable and replaceable concentrate container (302, 902) for holding concentrated soap or sanitizer is located within the housing (102). A concentrate pump (316) is in fluid communication with the concentrate container (302, 902). A diluent container for holding a liquid is also located within the housing (102) and a diluent pump (382, 901) for pumping the diluent is also included. The dispenser includes a mixing chamber (338) in fluid communication with the concentrate pump (316) and the diluent pump (382, 901). The dispenser includes an outlet. When concentrated soap or sanitizer is pumped from the concentrate container (302, 902), it mixes with diluent pumped from the diluent container to form a diluted mixture. The diluted mixture is dispensed at the outlet (350) of the dispenser.
