Hydromax is the most popular series sold by Bathmate. With over 1 million Bathmate Hydromax pumps sold, and 92%* of customers satisfied, Hydromax ensures real, lasting results. We currently offer 5 different Hydromax pumps.

Hydromax is simple to use. In the shower or bath, fill the pump with warm water, insert your penis and seal the pump to your body. Continue building the vacuum pressure by pumping out water, and you'll soon feel Bathmate start to take effect. Use for up to 5 minutes at a time, 3 times a day for maximum gains.

We've designed a Hydromax pump to suit practically any size of user, fitting anyone measuring between 1 and 9 inches (2.5-23 cm) when erect. Our most popular size is the Hydromax7 suited for users measuring between 5-7 inches (13-18 cm) when erect.

The results of using Hydromax significantly vary depending on the individual, and workout frequency. Some users have reported gains with a noticeably increased length/ girth after several months of regular use. We guarantee satisfying results, no matter what you're expecting.

When you buy from the official Bathmate site, we guarantee satisfying results. You'll have 60 days after purchase to see the effects of Hydromax for yourself - if you're not satisfied for any reason, we'll give you a 100% complete, no questions asked refund.

After a pump session, you'll see major temporary gains, right from the beginning. These typically fade quickly, with longer-lasting gains requiring regular workouts - just like any other kind of exercise.

Hydromax is our best-seller, harnessing the power of water instead of air like our other pumps, it offers 35% more power than the Hydro model.
