Description
The Bathmate Hydromax9 is the largest standard Hydromax size in Bathmate’s range, built for men measuring 7–9 inches erect who have outgrown the smaller Hydromax7 (5–7 inches). It works as a hydro pump rather than an air pump: water is the working medium, used in the bath or shower, and it spreads pressure more evenly around the shaft than a dry vacuum does. The clear polycarbonate cylinder is impact-resistant and lets you watch the chamber as pressure builds. A Swivel Bellows ring gives the pump head 360-degree rotation for positioning in the tub, while the Super Flow Latch Valve adds water one-handed under the shower without removing and reseating the whole unit. Where the pump meets skin, a removable soft synthetic rubber comfort pad seals around the base and testicles — it’s the one part that needs rinsing after every session.
Bathmate builds the Hydromax9 at its own UK factory from medical-grade, skin-safe materials, and the line is FDA-registered. The effect is temporary engorgement created by water pressure, not a permanent size increase, and Bathmate’s own guidance calls for starting on a low pressure setting and building up gradually rather than jumping straight to maximum, keeping sessions to around 15 minutes, and capping use at five sessions a week rather than longer or more frequent sessions. Stop a session right away if petechiae show up — small clusters of burst capillaries under the skin — along with bruising, persistent numbness, or sharp pain. Anyone with a clotting disorder or taking anticoagulant medication should get a clinician’s sign-off before using a vacuum device like this one.

Frequently Asked Questions
Will the Hydromax9 give a permanent increase in size?
The Bathmate Hydromax9 creates temporary engorgement through water pressure rather than a permanent change — any size increase from a session fades afterward, and Bathmate makes no guarantee of lasting results.
How should pressure be built up during a session?
The Bathmate Hydromax9 should begin on a low pressure setting, increasing gradually instead of jumping straight to maximum, with sessions kept to around 15 minutes and used up to five times a week, per Bathmate’s guidance.
Is the Hydromax9 suitable for everyone?
The Bathmate Hydromax9 needs a clinician’s sign-off beforehand for anyone with a clotting disorder or taking anticoagulant medication, and a session should stop immediately if petechiae, bruising, persistent numbness, or sharp pain appear.
