The Bathmate Hydromax 8 is a water-powered penis pump from Bathmate's best-selling Hydromax series, designed to be used in the bath or shower. Unlike traditional air pumps, it works using water to create even pressure around the penis, and getting started is as simple as adding water. Sized for users who measure between 16 and 21 centimetres when erect, the Hydromax 8 is a popular choice for those trying pump use for the first time or upgrading an existing routine.

Trusted series: The Hydromax line is one of Bathmate's most popular ranges, used by people around the world.
Bath or shower ready: Because it relies on water, it is built to be comfortable to use while bathing or showering.
Why Choose the Hydromax 8?
Water-based pumps like the Hydromax 8 are often preferred over air pumps because water helps spread pressure more evenly and comfortably. Bathmate has built the Hydromax series around this principle, and model 8 sits within that range for a specific size band. If you measure between 16 and 21 centimetres when erect, this is the version aimed at you.
It suits anyone curious about pump use who wants a recognisable, easy-to-use option, as well as returning users who prefer to stay within a trusted series. As with any pump, comfort and experience vary from person to person, so it is worth building up use gradually.

How to Use and Care
Use the Hydromax 8 in the bath or shower for best results. Fill the pump with warm water, place it over the penis to form a seal, then pump gently to remove excess water and create even pressure, always keeping within a comfortable level. Start with short sessions and build up gradually rather than over-pumping. After use, empty the pump and rinse it thoroughly with clean, warm water, then allow it to air-dry completely before storing it somewhere clean and dry. If you feel any discomfort, release the pressure and stop, and follow the manufacturer's instructions for detailed guidance.

Frequently Asked Questions

Which Hydromax size should I choose?
The Hydromax 8 is designed for users who measure between 16 and 21 centimetres when erect. Choosing the model that matches your size helps ensure a proper seal and comfortable use.
How do I clean and store it?
Rinse the pump with clean, warm water after each session and let it air-dry fully. Store it somewhere clean and dry, away from direct heat and sunlight.
