The Bathmate HydroXtreme 11 is designed for men who want to increase penis size, improve length and girth, and support stronger, more consistent erections, while benefiting from the highest level of capacity and control available in the HydroXtreme range. By using water to create pressure instead of air, it helps promote better blood flow while delivering a more even and consistent pumping experience.
What sets the HydroXtreme apart is its patented handball pump system, which allows for precise, incremental control over pressure during each session. Instead of relying solely on the standard bellows, users can fine tune intensity more gradually, creating a more controlled and customizable pumping experience.
Many users find the Hydromax bellows system places too much pressure on the pelvic area and prefer the HydroXtreme design, as the handball attachment reduces the need to press firmly against the body.
The HydroXtreme 11 is designed for men measuring approximately 9 to 11 inches erect, with a maximum girth capacity of up to 8.5 inches (2.70 inches diameter). Its extended and widened chamber provides the largest internal space available in the Bathmate range for both length and girth expansion.
It is well suited for users who want greater control over pressure during each session while requiring maximum capacity for expansion. With the addition of the handball pump system, it allows for more precise, incremental adjustments, making it the most advanced option compared to standard Hydromax models for those seeking improved control, comfort, and performance at the highest level.
If you are below this size range, a smaller model will provide a better fit. If you do not require this level of capacity, a more compact model may offer better control and comfort.
The HydroXtreme 11 is built for durability, precision, and performance, with features designed to support maximum length and girth capacity, secure fit, controlled pressure, and a fully advanced pumping experience.
The HydroXtreme 11 Kit includes the HydroXtreme pump with handball attachment plus a complete accessory kit designed to support cleaning, maintenance, storage, and a more complete setup.
The HydroXtreme 11 is designed to help increase penis size, support gains in length and girth, improve erection quality, and promote stronger blood flow. What sets it apart is the added level of control combined with maximum internal capacity, allowing users to gradually adjust pressure for a more precise and consistent experience.
With the handball pump system, users can fine tune intensity throughout each session, helping create a more customized routine while maintaining comfort. Its extended and widened chamber provides the greatest expansion potential available, making it the preferred option for users seeking maximum performance and capacity.
For users who want the highest level of capacity, precision, and control, the HydroXtreme 11 represents the largest advanced option in the Bathmate hydropump range.
The HydroXtreme 11 is designed for men measuring approximately 9 to 11 inches erect, with a maximum girth capacity of up to 8.5 inches (2.70 inches diameter). As the largest Bathmate model available, its extended and widened chamber provides maximum internal space for both length and girth, while maintaining effective pressure and comfort during use.
Use our Bathmate size guide to compare measurements and select the correct model before purchasing.
If you measure below the 9 to 11 inch range, consider the HydroXtreme 9 for a smaller chamber and more compact fit.
If you do not require this level of width, consider a model with a narrower chamber for a more controlled fit.
HydroXtreme models include a handball pump for precise pressure control, while Hydromax models rely on a manual bellows system. Choose HydroXtreme if you want more control and a more advanced pumping experience.

Use the HydroXtreme 11 in water for approximately 10 to 15 minutes per session, adjusting pressure gradually using the handball pump for optimal control and comfort. Want a clearer idea of how results develop with regular use? Read our Bathmate results timeline (30, 60, and 90 days).
The HydroXtreme 11 is the largest Bathmate pump available, offering more chamber length than any Hydromax model.
It provides maximum size capacity and includes the handball pump for controlled pressure.
No, the size 11 is exclusive to the HydroXtreme range.
It is designed for users who require the largest available chamber size and want to generate stronger pressure using the handball pump, giving advanced users more control over intensity during use.
No, it is generally recommended for experienced users due to its size.
The HydroXtreme can allow users to reach higher pressure more easily thanks to the handball pump. While both models operate within safe limits, the handball makes it easier to build and maintain stronger, more controlled pressure compared to relying only on manual force.
No, it is typically only available as a full kit.
The kit includes the pump, handball, and accessories such as a storage bag and cleaning products.
Due to its size, it requires experience, but the handball improves control.
Yes, it is designed for water-based use.
