Refillable soap systems are simple mechanically, but small details — dilution ratios, pump maintenance, and storage — make a bigger difference in cost and longevity than most people expect. The FAQ below covers the dispenser mechanics and soap-stretching questions people search most.

If you only take two things from this page: keep bar soap somewhere it can fully dry between uses (this alone can double how long a bar lasts), and don’t be afraid to dilute liquid hand soap slightly with water, since most formulas are concentrated well past the point needed for effective handwashing. Both are free changes that compound over a year of regular use.
