Bathmate Hydroxtreme 9 is a hydro-based penis pump designed for use in water — bath or shower — making it a more comfortable alternative to traditional air-based pumps. Instead of relying on vacuum suction alone, this system uses water pressure to create a seal around the penis, supporting firmer erections and temporary size enhancement during use.
Who This Pump Suits
Sized for men with an erect length between 7 and 9 inches (17.5-23 cm), this pump accommodates a fuller starting size. If you’re smaller or larger, Bathmate offers other models in the range — but this one is built for those who need that extra capacity and length.
The Bellows System and Comfort Ring
The bellows mechanism allows you to control pressure with ease, compressing and releasing as needed during your session. The comfort ring — a soft, supportive seal that sits around the base — spreads pressure more evenly and reduces discomfort around the testicles. It’s also removable, so cleaning is straightforward.
How It Works
Fill the cylinder with warm water in the bath or shower. Insert your penis, press the pump against your body to form a seal, then compress the bellows to create suction. The water displaces air and draws blood into the penis, supporting a fuller erection. Sessions typically last 15-20 minutes, with pressure released gradually by pressing the valve at the top.
Material and Build
The cylinder is made from hard-wearing plastic, measuring 33.7 cm in length and 6.1 cm in width. No batteries, no charging — just you, warm water and controlled pressure.
