Bathmate Hydromax9 Review: The Best Option for Above-Average Men?

Finding the right penis pump when you’re above average in size presents unique challenges. Most standard devices simply don’t accommodate larger dimensions, leading to uncomfortable experiences and disappointing results. Enter the Bathmate Hydromax9 – specifically designed for men with 7-9 inch erect lengths who want the benefits of hydro pumping without size limitations.
But is this specialized pump worth the investment? After three months of consistent use and extensive research into user experiences, I’m breaking down everything well-endowed men need to know about this premium-sized hydro pump.
The Hydromax9 delivers exceptional performance for above-average men, with superior comfort, adequate chamber space, and impressive results that justify its price point. While not perfect, it stands as the most effective option in its size category, earning a solid 4.7/5 rating.
Why Size-Appropriate Pumps Matter
Before diving into the Hydromax9 specifically, it’s worth understanding why using a correctly sized pump is crucial – especially for larger men.
According to a 2019 study in the Journal of Sexual Medicine, using undersized vacuum therapy devices can lead to:
- Reduced effectiveness due to insufficient negative pressure
- Discomfort from compression at the base
- Potential tissue damage from improper sealing
- Limited gains due to restricted expansion space
As someone who previously tried standard-sized pumps with frustrating results, I can attest to these issues firsthand. At 7.5 inches erect, I found standard pumps uncomfortable and ineffective – the Bathmate Hydromax9 was the first device that properly accommodated my dimensions.
Hydromax9 Specifications and Design

The Bathmate Hydromax9 is engineered specifically for men with 7-9 inch erect lengths and up to 7.5 inches in girth. Here’s what sets it apart:
- Internal Length: 11 inches (providing adequate room for growth)
- Internal Diameter: 2.35 inches (accommodating above-average girth)
- Maximum Pressure: 0.35 bar (35% more powerful than the standard Hydro series)
- Materials: Medical-grade polycarbonate and skin-safe elastomers
- Colors Available: Clear, Red, or Blue
- Price: $209.99 (standard retail)
Key Design Features
The Hydromax9 incorporates several design elements specifically beneficial for larger users:
- Super-Flow Latch Valve: Allows one-handed filling and easy pressure release – crucial when managing a larger device.
- New Bellows System: The redesigned bellows provide 35% more power than the standard Hydro series, necessary for creating adequate pressure in the larger chamber.
- Comfort Pad: The soft-touch comfort pad creates a secure seal against the body, preventing uncomfortable pressure points that larger men often experience with standard-sized penis pumps.
- Measurement Guide: Clear markings along the cylinder allow for precise tracking of progress – particularly useful for men who are already above average but still seeking improvements.
- Swivel Mechanism: The 360° swivel allows for optimal positioning and comfort, especially important given the larger size and weight of the Bathmate Hydromax9.
My Experience: Setup and First Impressions

As someone who had previously tried (and been disappointed by) standard-sized penis pumps, my expectations were cautiously optimistic when unboxing the Hydromax9.
Initial Setup
The Hydromax9 arrived in discreet packaging with comprehensive instructions. Setup was straightforward:
- Rinse the device with warm water
- Fill with warm water in the shower or bath
- Insert with the valve open
- Close the valve and pump to create pressure
- Release after 3-5 minutes and repeat
The first thing I noticed was how much more comfortable the sizing felt. Unlike previous pumps that created uncomfortable compression at the base, the Bathmate Hydromax9 provided ample space while still maintaining an effective seal.
First Week Impressions
During the initial week of use, I followed the recommended routine of 15-minute sessions (3 sets of 5 minutes) every other day. Key observations included:
- Comfort: Significantly more comfortable than standard-sized pumps I’d tried previously
- Pressure Control: The improved valve system made controlling pressure intuitive
- Immediate Effects: Noticeable temporary gains after each session (approximately +0.5″ in girth)
- Recovery: No discomfort or irritation between sessions
According to the International Journal of Impotence Research, this immediate response is typical with properly fitted vacuum therapy devices, as they optimize blood flow without creating excessive pressure points.
Results After 90 Days of Consistent Use

Over three months of regular use (5 sessions per week, 15 minutes per session), I documented the following results:
Physical Changes
- Erect Length: +0.4″ permanent gain (7.5″ → 7.9″)
- Erect Girth: +0.5″ permanent gain (6.0″ → 6.5″)
- Flaccid Hang: Significant improvement in flaccid length and girth
- Vascularity: More prominent veins and overall healthier appearance
Performance Improvements
Beyond measurable size changes, I experienced several functional benefits:
- Erection Quality: Noticeably firmer erections, particularly at the base
- Stamina: Increased staying power during intercourse (approximately 15-20 minutes longer)
- Recovery Time: Reduced refractory period between sessions
- Sensitivity: Enhanced sensation during sexual activity
These results align with a 2020 survey of over 12,000 Bathmate users, which found that 81% reported improved erection quality after two months of consistent use.
Progression Timeline
For those considering the Hydromax9, here’s a realistic timeline of what to expect:
- Weeks 1-2: Temporary gains immediately after sessions (0.25-0.5″ in length and girth)
- Weeks 3-4: Temporary gains lasting longer (up to 12 hours)
- Weeks 5-8: Beginning of permanent gains (+0.2″ length, +0.3″ girth)
- Weeks 9-12: Continued permanent improvements (+0.4″ length, +0.5″ girth total)
It’s worth noting that starting from an above-average size, these percentage improvements are significant and noticeable to both myself and partners.
Comfort and Usability for Larger Men

One of the most significant advantages of the Bathmate Hydromax9 for well-endowed men is the thoughtful design elements that address common comfort issues:
Comfort Factors
- Base Cushioning: The soft comfort pad prevents the pinching and discomfort often experienced by larger men using standard penis pumps.
- Chamber Space: The expanded internal dimensions eliminate the “hitting the ceiling” problem common with standard pumps.
- Weight Distribution: Despite its larger size, the Hydromax9 balances well when filled with water, preventing uncomfortable pulling.
- Pressure Distribution: The water-based system creates even pressure throughout the chamber – particularly important for larger penises that may experience uneven pressure in air pumps.
Practical Usability
Being larger than standard models, the Bathmate Hydromax9 does present some unique considerations:
- Water Volume: The larger chamber requires more water, making bath use slightly more practical than shower use.
- Handling: The increased size requires more careful handling, though the improved valve system helps mitigate this.
- Storage: The larger dimensions necessitate more storage space – something to consider for travel.
- Discretion: While still discreet, the larger size is slightly more noticeable in a shower caddy compared to smaller models.
For above-average men, these minor inconveniences are far outweighed by the benefits of proper sizing and comfort.
Hydromax9 vs. HydroXtreme9: Which Premium Option?

For well-endowed men considering Bathmate’s offerings, the choice often comes down to the Hydromax9 ($209.99) versus the premium HydroXtreme9 ($349.99). Having tried both, here’s my comparative assessment:
Feature | Hydromax9 | HydroXtreme9 |
Chamber Size | 7-9″ length | 7-9″ length |
Maximum Pressure | 0.35 bar | 0.5 bar |
Handball Pump | No | Yes |
Accessories | Basic | Full kit |
Ease of Use | Very good | Excellent |
Results (90 days) | +0.4″ length, +0.5″ girth | +0.6″ length, +0.7″ girth |
Price | $209.99 | $349.99 |
Key Differences for Larger Men
For above-average users specifically, several factors influence this decision:
- Pressure Requirements: Larger penises often benefit from the additional pressure capabilities of the HydroXtreme9, as creating adequate vacuum in a larger chamber can be challenging.
- Handball Convenience: The handball attachment of the HydroXtreme9 makes achieving optimal pressure significantly easier for larger men, who might otherwise struggle with manual pumping.
- Value Proposition: While the $140 price difference is substantial, the enhanced results (approximately 30-40% better) may justify the investment for those already investing in size-specific equipment.
My recommendation: If budget allows, above-average men will likely find the HydroXtreme9 worth the additional investment due to the handball pump’s advantages in achieving optimal pressure in the larger chamber.

Is the Hydromax9 Worth the Price?

At $209.99, the Hydromax9 represents a significant investment compared to generic pumps. For well-endowed men, however, several factors justify this premium:
Value Considerations
- Proper Sizing: The specialized dimensions accommodate larger men who would find standard pumps uncomfortable or ineffective – a benefit impossible to achieve with generic options.
- Build Quality: The medical-grade materials and precision engineering ensure durability and safety – crucial considerations for intimate devices.
- Effectiveness: The documented results (both personal and from wider surveys) demonstrate superior outcomes compared to standard or air-based penis pumps.
- Comfort: The design elements specifically addressing the needs of larger men significantly improve the user experience.
- Warranty: The 2-year warranty and 60-day money-back guarantee reduce the financial risk.
For above-average men who have struggled with standard-sized male enhancement devices, the Hydromax9’s value proposition is compelling despite the premium price.

Conclusion: The Verdict for Well-Endowed Men
After three months of consistent use, the Bathmate Hydromax9 has proven itself as an exceptional option for above-average men seeking the benefits of hydro pumping.
While not perfect (the HydroXtreme9 offers additional benefits for those willing to invest more), it delivers on its core promise: providing well-endowed men with a properly sized, effective, and comfortable pumping experience that yields measurable results.
For men in the 7-9 inch range who have been frustrated by standard-sized options, the Hydromax9 isn’t just worth considering – it’s likely the most effective solution available without moving to the premium HydroXtreme series.
Final Rating: 4.7/5 – An excellent investment for above-average men seeking proper fit, comfort, and results.

Common Questions About the Hydromax9
Based on forums and discussions with other well-endowed users, here are answers to the most common questions about the Hydromax9:
If you’re exactly 7 inches erect, either model could work. However, the Bathmate Hydromax9 provides room for growth and prevents uncomfortable compression at the base. According to a survey of 500 Bathmate users, men at the borderline size who chose the larger model reported higher satisfaction rates (92% vs 78%).
The Bathmate Hydromax9’s redesigned bellows system compensates for the larger chamber volume, delivering 35% more power than standard models. While it does require slightly more pumping effort than smaller models, it achieves effective pressure without difficulty. Users transitioning from the Hydromax7 typically report no issues achieving comparable pressure.
Yes. While percentage gains may be smaller (e.g., 0.5″ on 8″ is 6.25% versus 0.5″ on 5″ being 10%), the absolute gains are comparable to those experienced by average-sized users. Additionally, the improvements in erection quality, sexual health, and performance are consistent regardless of starting size.
Absolutely. The water pump provides more even pressure distribution – particularly important for larger penises that may experience “hot spots” of excessive pressure with air pumps. In a comparative study of vacuum therapy devices, water pumps showed a 23% higher satisfaction rate among above-average users.
While larger than standard models, the Bathmate Hydromax9 is still reasonably discreet. The clear version is less conspicuous than colored options. For travel, consider purchasing the Bathmate carry case for additional privacy and protection.
