Frequently asked questions about Bathmate sizes

What happens if I choose a large pump?
The Bathmate pump requires water to run its mechanism, the water creates suctions when pulled out. Empty space in the cylinder causes suboptimal pressure and consequently reduces pumping performance.
What is the growth room for all Bathmate pumps?
The growth chamber on the Bathmate pump is ± 1.5 inches. For example, if a person has an erection length of exactly 7 inches and takes a Hydromax7 pump that falls into the 5-7 inch range, then the maximum length growth is 8.5 inches.
What are the maximum inches of growth with Bathmate?
Your current penile erection determines it, for example, if you are exactly 5.5 inches and take one of the models from the 5-7 inch range, then your difference is 7-5.5=1.5 and the remaining growth space is 1.5 inches. The final result, your size + difference + growth space then 5.5 + 1.5 + 1.5 = 8.5. Then the maximum estimated growth is 8.5 inches. This is not a standard calculation and each user will be different depending on their erection size.
