Bathmate Size Guide

What size Bathmate is right for me?


The 2 most common questions we get asked are the following

1).  Which Bathmate will fit me?

2)  How do I know what size Bathmate I need?

Yes, they are the same question, just written or asked differently on a daily basis. So we went ahead and created a Bathmate Size Guide to help you figure out what size of Bathmate will fit you on your journey to personal enhancement.

Step 1.  Choose your Bathmate model (please note measurements refer to erect penis length):

a)  Bathmate Hercules: The original and longest selling hydropump to help men get bigger, thicker, cum harder, last longer, and reduce E.D. This pump is ideal for most average-sized men under 7.5" in length (erect) and under 1.9" in girth measuring left to right at the widest point. Effective. Economical. Reliable.


b)  Hydromax X30: The latest in male enhancement hydropump technology. This pump brings new features to the table such as a latch valve for easier filling, removable comfort pad with improved comfort and padding, new rubber bellows design for 30% more power. Up to 250% for efficient than an air pump. This pump is also ideal for most average-sized men under 7.5" in length (erect) and under 1.9" in girth measuring left to right at the widest point. More power equaling quicker results.


c)  Hydromax X40: The big brother of the X30. Advanced penis pump technology but 15% larger in size.. For men already more than 2" in girth and/or over 7.5" in length. Includes a locking latch valve, swivel bellows for maximum viewing, removable comfort pad. Used by pro's in the adult industry. One of our best sellers.


d)  Bathmate Goliath: For ambitious men already 9" or longer in length with above average girth. The Bathmate Goliath is 30% larger than the Bathmate Hercules. Includes a shower strap and storage case. Nothing in terms of size is average about this pump. Most to not buy this pump until it's time for them to graduate up from the smaller sizes.

e)  Hydromax X30 Xtreme: Same size as the regular X30 but sold with hand ball pump and every accessory you'll ever need. Including a support strap, protective case, long insert comfort pad and more. The Hydromax X30 Xtreme is for the Extreme P.E. user who wants the best results with the best of the best technology.

f)   Hydromax X40 Xtreme: Same size as the regular X40 but includes hand ball pump, towel, measuring gauge, hard-shell storage case, support strap, cleaning brush, and more. Everything you need for your hydro pump. Again, this is the perfect pump for men already above average in length and girth looking to achieve bigger gains in size and endurance the fastest way possible with the most amount of comfort.

Important: Keep in mind that the internal length will decrease by roughly 38mm (1.5") once a proper seal is achieved. Take this into consideration when choosing the correct size pump for you. DO NOT simply buy the biggest pump. Take measurements and buy for YOUR right size!
