Maximised Penis Pump Performance.

Bathmate HydroXtreme11 is the single largest penis pump in the world, and the latest model from our advanced Bathmate HydroXtreme Series. Designed for men who measure over 9 inches when erect, our hydropump drastically increases blood flow to the penis, creating harder, longer lasting erections, making a real improvement to your sex life.


  • Proven, long-lasting improvements for sexual power.
  • Better erections and sexual stamina.
  • Guaranteed satisfaction or full refund.


  • Fits sizes 9 - 11" (23 - 28cm)
  • Certified Skin-safe.
  • World's most powerful pumps.


As with our other Bathmate penis pumps, the HydroXtreme11 is simple to use, and delivers real results. Simply fill the unit with warm water, and seal it against your body for three 5-minute sessions to see real results. If you’re an experienced user, the HydroXtreme11 lets you add an additional level of pressure to your workout via the included handball attachment, maximising pump pressure to create even stronger results.

Given the size of the Bathmate HydroXtreme11, we really have to recommend double checking your penis size before purchase. If you’re not the recommended size, you won’t get the full benefits of the pump (though we don’t think there’s much chance of anyone being too big for it). Head over to our Penis Size Calculator for an in-depth look at how to accurately measure your size.

HydroXtreme means absolutely unbeatable results. These are the most powerful penis pumps legally sold, giving you the absolutely highest level of pressure that can safely be used. 

Formerly known as the Hydro Xtreme X50, we’ve rebranded the HydroXtreme11 to give our customers an easier way to find a pump that’s perfect for them. With the HydroXtreme11 being a real niche product given its size, we only make a clear model of the pump, and stocks are somewhat limited (so make sure you don’t miss out!).

As the official Bathmate website, we’re able to offer you a 60 day no-questions-asked returns policy on all of our hydropumps, though if you’ve already used the return policy you won’t be able to claim it again. We also offer completely free shipping and a two-year warranty for our customers, though you can also choose expedited delivery options and longer-lasting warranties.

In order to get the very best performance out of your HydroXtreme11 penis pump, we recommend regular usage. Think of it as a different kind of workout – real results come from regular activity, not just occasional sessions.

Like all of our Bathmate products, the HydroXtreme delivers real results – head through to our Bathmate Reviews section to see what our customers have to say, or check out Bathmate Videos to see the proof for yourself.

All of our Bathmate HydroXtreme penis pumps include a set of useful accessories for your Bathmate, including the following items. However, we offer a lot more Bathmate Accessories to maximise your gains – click through to find out more:
