Importance of size

It is wrong in believing that choosing a bigger Bathmate could last longer and have more gains. It will be counterproductive and will not be effective. It is very important to choose a Bathmate that best suits your size. Please choose your Bathmate according to the sizing chart. If you are uncertain about which one to get, please kindly get in contact with us.

*No refunds nor exchanges is allowed for choosing wrong size.

How to measure properly

Measuring Length
Measure your erect penis with a ruler pressed lightly onto your pubic bone. You`ll find a ruler is easier than a tape measure. Record the measurement from the pubic bone right up to the tip of your penis.

Measuring Girth (Circumference)

Measure the circumference of your erect penis around the middle of your shaft. You’ll find a tailors tape measure is easiest, but a piece of string wrapped round and then measured against a ruler after will do.
