The capacity of a soap dispenser is important. Large soap dispensers and small soap dispensers both have their place in residential and commercial installations. Too large and the contents can solidify or go bad. Too small and it will have to be filled too often. A common commercial size bottle of soap is 1 gallon or about 3735ml. A gallon of soap would fill a 1000ml reservoir almost full four times. A large capacity soap dispenser would hold 17oz to 51oz or more. These large capacity soap dispensers would be considered commercial soap dispensers. Residential and hotel soap dispensers may not need the large capacity. Use the chart below to determine which capacity and size of reservoir would suit you application best.
