If you measure around 3 inches or less when erect, you’ve found an ideal hydropump option.

With a powerful water-based design, Hydromax3 generates real, lasting results, improving size, and erection quality for a major self-confidence boost.

After about a month’s regular use (or before), you’ll see noticable, lasting improvements.

The Bathmate Hydromax3 is designed to suit users measuring up to 3 inches when erect, and delivers ideal performance for those between 1 and 3 inches.

We’d recommend starting off with a jelqing routine as a first step if you’re below this level.

Bathmate Hydromax3 uses water power to significantly increase size.

You can also get the Bathmate shower strap and the cleaning kit.

Bathmate Hydromax3 features:

  • Waterproof

Size and material:

  • Designed for anyone measuring under 3" / 7.62 cm when erect.

🔥 Pleasure Scale™ Rating

This Toy: ♻️ Rotation Regular



Performs well, consistently satisfying, and fits many moods.

Who is this penis pump for?

The Bathmate Hydromax3 is ideal for:

  • Individuals with a starting length under 3 inches erect looking to safely increase size and improve vascularity.
  • Folks experiencing mild to moderate erectile issues who want to enhance erection strength and duration naturally.
  • New users to penis pumping—the smaller size and controlled water-based pressure make it beginner-friendly.
  • People seeking non-invasive solutions for confidence-building and improved sexual wellness.

How to use the Bathmate Hydromax3?

  1. Fill the pump with warm water in the shower or bath, leaving some room for pressure build-up.
  2. Insert the penis into the chamber while flaccid or semi-erect, ensuring a comfortable seal with the base.
  3. Press the pump towards your pubic bone to expel air or excess water and create a vacuum.
  4. Pump 3–5 times until comfortable pressure is achieved. Add more pumps through the session as needed.
  5. Use for up to 15 minutes, pausing every 5 minutes to release pressure and ensure safety.

Great positions to try:

  • Standing in the shower: Best for use with the optional Bathmate Shower Strap.
  • Sitting comfortably in the bathtub: Offers full relaxation and helps maintain a steady seal.
  • Leaning at the sink or edge of tub: Allows for easier control and pressure adjustment.

How to clean and care for the Bathmate Hydromax3?

  • Cleaning: After each use, rinse with warm water and a mild soap or toy-safe cleaner.
  • Drying: Let air dry completely or use a clean towel to pat dry the interior and gasket areas.
  • Lubricant compatibility: Lubes aren’t typically used with this toy, but if desired, opt for water-based only on the base seal.
  • Storage: Store upright in a cool, dry place. Keep out of direct sunlight and avoid contact with other soft toys or silicone items.

Penis pump practical use info:

  • This toy is meant to be used alone
  • It can be used externally

Additional information:

  • This toy might be suitable for folks who have trouble maintaining erection or experience ED because when used routinely it improves blood circulation within the penis, leading to longer and firmer erections.
  • When combined with a cock ring, this toy might help achieve an erection sufficient for sexual intercourse.

Special considerations when using Bathmate Hydromax3:

  • Needs active grasp to be put on/off
  • Needs reach to access genitals
  • Needs strength in arm/hand to push the pump downwards

User experience tips:

  • Warm the water before filling the Hydromax3 to soften tissues and enhance blood flow—that means better comfort and results.
  • Shave or trim pubic hair around the base for better suction and a more secure seal—less water loss, more power.
  • Use the Bathmate Shower Strap for hands-free support, especially during longer sessions—your arms will thank you.
  • Start with 10-minute sessions, 3–5 times per week to build a routine without overdoing it—consistency is key for gains.
  • For extra post-pump effect, apply a cock ring directly after to help maintain fullness and firmness longer.
  • Use a mirror the first few times to observe your placement and see how your body responds—helps fine-tune your angle and seal.
