Choose by fit
The 3-to-5-inch figure is the maker's erect-length range. It is not a chamber-width measurement, a target size, a medical classification, or a promise that the opening will seal comfortably. Measure erect length and girth, compare both with current Bathmate sizing guidance, and make sure the opening can sit against the body without trapping the testicles. If your erect length falls outside the maker's range or the opening does not fit comfortably, choose a different size rather than compensating with extra pressure.
Product design and included parts can change. Inspect the unit you receive and follow its enclosed instructions wherever they differ from this page.
Use the included instructions
Read the enclosed Hydromax guide before first use. Bathmate directs users to begin with a flaccid penis, fill the pump with warm—not hot—water, keep the testicles outside the seal, and apply only the minimum comfortable vacuum. Keep the release valve accessible throughout use.
The official guide recommends removing the device every 2 to 3 minutes, allowing the penis to retract, and gently massaging it in the flaccid state for up to 2 minutes before reapplying. It allows no more than three cycles and no more than 15 total minutes in any 24-hour period. The current Bathmate routine page also advises limiting use to five days per week. Follow the instructions supplied with your unit if they are more restrictive.
Important vacuum-pump limits
- Use only while awake, unimpaired, and able to monitor pressure and sensation continuously.
- Do not use if you cannot operate the release mechanism promptly or have reduced pain sensation in the penis.
- The maker says not to use the device with sickle cell disease, a history of prolonged erections, a bleeding disorder, or while taking blood-thinning medication. Consult a qualified clinician before use if you have erectile-dysfunction symptoms or another condition listed in the guide.
- Excess pressure or vigorous pumping can cause bruising or injury. Release the vacuum and remove the pump immediately for pain, marked discomfort, numbness, unusual color change, coldness, swelling, or bleeding.
- Do not fall asleep with the device in place and do not use it while impaired by alcohol or drugs.
- The official guide limits the Hydropump to one user and advises against lubricant because the device is intended for water use.
This page does not promise permanent enlargement, treat erectile dysfunction, replace medical care, diagnose a medical condition, or guarantee a particular result. Vacuum use can aggravate some pre-existing conditions. Persistent symptoms or an erection that does not subside require prompt medical advice.
Release, cleaning, and storage
Before beginning, identify and test the release control without a body seal. To remove the pump, press the valve cap inward to release the vacuum and slide the device off only after pressure has released. Never pull against an active vacuum.
Before first use and after each session, wash the Hydropump with warm, clean soapy water and rinse thoroughly as directed by Bathmate. Let it dry completely, then store it dry and away from direct sunlight. Inspect the chamber, gaiter, bellows, valve, seal, and comfort insert before each use; do not use damaged, cracked, loose, blocked, or deteriorated parts.
