How Hydro works

The Hydro combines cutting-edge design with your body’s natural abilities to give you a safe, effective way to boost blood flow, increase size, and build confidence.  It’s simple, discreet, and convenient.

The science

Bathmate harnesses the power of water-based pressure to create a vacuum effect that naturally increases blood flow to the penis. This surge in circulation helps stretch and expand the erectile tissue, leading to thicker, firmer, and more responsive erections over time. With regular use, the pump encourages healthier vascular performance and greater oxygenation, promoting stronger, more consistent results without the need for medication.

How to use

Bathmate fits effortlessly into your daily routine - just use it in the bath or shower. Fill the chamber with warm water, insert your flaccid penis, and press the pump against your body to create a secure vacuum seal. Hold for up to 3 minutes, release the pressure, and repeat the process up to three times, staying within a 15-minute session. Finish with a light massage to aid recovery and circulation.ate work its magic, and follow our pumping guidelines.

Is it safe?

Bathmate is designed with safety at its core, making it a reliable choice for daily use when following the recommended guidelines. Unlike traditional air pumps, Bathmate uses water to apply balanced pressure evenly across the penis - helping prevent discomfort and reducing the risk of over-pumping. Each unit is FDA-registered and equipped with key safety features, including pressure control valves and comfort-enhancing seals.

Expected results

Bathmate is built for results you can feel and measure. Right from your first session, you may notice increased fullness and temporary size gains as blood flow improves. Stick to the routine, and within a few weeks, your body begins adapting - delivering firmer erections, greater stamina, and enhanced performance. By weeks 8 to 12, users commonly report gains in both girth and length, along with a noticeable boost in sexual confidence. After week 16, progress tends to hold for a long time.

Your satisfaction, guaranteed.

As advertised

It's not magic it takes commitment. But this will bring out your full potential within a few weeks. There's a bit of a learning curve, but the results and ease of use once you figure it out make it so worth it. Never had an issue with erections, but now I can rep a 5lb dumbbell with it 🤣

Bought this 9 years ago.

Bought it nine years ago and this is and always will be the best of the best pumps you could use. The results I got from this are better than any other pump I've used. My ex wife legitimately and I'm being dead serious with this legitimately her mouth started watering so much, she was drooling and at a loss for words when she was the sheer girth. She could not keep her hands off of me. Not that I would complain, but if you've got the coin try it because it is useful and the work put in stays to a testament to what it is.

Very pleased with results so far

I like to wear a ring on Mr. Johnson daily. I've gone from securely wearing a single 28mm to securely wearing twin 30mm. So I know girth is improving and have noticed an increase under vacuum from 6 inches to 7 inches, again under vacuum. But I have also noticed that during my erection, even when not super hard, that it appears to be longer than before.

Noticeable results!

I have been using my Hydro 7 for around six weeks. By the second week, my wife remarked that I seemed bigger. I could already see and feel stronger erections within a few days, but I also felt longer and thicker. I use my Hydro 7 four to five times a week, following the included instructions, and I'm extremely happy with the results. My penis looks better than it ever has, and feels even better.

Works as intended

It's easy to over do and blow blood vessels which can cause more problems then the device can fix. So be careful. I've noticed slight gains. But what point is there in having a bigger tool if no one wants it in their garden? Lol

Average guy and wow!!!

Im just your average guy not your most fit but on the chubby side. With that being said anyone any size can benefit from this amazing tool. Ive tried air pumps, pills etc. This thing works but.... consistency is everything.
Ive been using it for 4 months now 2 weeks on 1 week off and I have had great results just ask my wife. My wife begs for the pump now so it makes it easy to us. Im to the point I want to try the max but it's hard to give up the original.
My results are 1" in thickness and just under inch in length. Like I said my wife loves it! I have also noticed a my stamina has increased which is aways a win. If you on the fence just buy it i promise it works and makes your member look great.

Hydro7 review

I will say that I feel like I have noticed an increase in the amount of times I get an erection at night. I’m woke up in the middle of the night multiple times with a rock hard erection. I have not noticed any growth in girth and that is the key reason I chose this product. I am hoping I will notice something soon. I use it regularly just like my workouts I schedule my bathmate training daily and take 2 days off.

Just Doing a Little Maintenance

I did not come to Bathmate to hope for a miracle growth tool. I came to keep what I’ve had and enjoyed for many years. I am a 59 year old, married, very sexually active man who is feeling the effects of time on his body.
I currently sit at 6.5” length and 5,5” girth, so I am fine with where I am at size-wise, and so is my wife. But with those 59 years, my body was becoming a little noncooperative at times, one of those being reduced circulation. And with that, I found my flaccid hang is now less heavy and full, and I was turtled more than I am showing off, and as a result, my erection quality was beginning to fade.
So after a lot of pills, supplements, exercises, jelqs, you name it, nothing seemed to affect the root cause - decreased circulation. I did my homework, read testimonials, and researched what was physically happening to my body. And in the end, I decided to give Bathmate a try.
I bought the Hydro7 as my introductory device to see if water pumping therapy was the answer to my issues. I love it because it is discrete, easy to use, and because of the pumping gates, it is impossible to over-pump to an unsafe level. Then you shower as usual, letting the pump do the work while you bathe. It’s that simple.
After only 1 MONTH, I am already impressed with the positive changes I see happening in my manhood. Because of daily use for 15 minutes a session, I now have that fuller flaccid more often and less turtling during the day. I can actually feel myself fuller as I go through the day. The pump is simple to use and the water “pull” is far superior to and more comfortable than the air pump I had used in the past. My flaccid fullness has returned. Again, I did not get the Hydro7 hoping for growth, as wife and I are more than content with my erect size, but that has even changed in the MONTH I have been using this. My erect size has gone from 6.5” to 6.75”, and my erect girth has increased from 5.5” to 5.75 — in just one month of use. If this keeps up, I will have to GLADLY upgrade to the next pump, as I will be maxing this one out. A good problem to have!
If you are on the senior side of life and feeling the effects of time on your equipment, I cannot endorse the Bathmate products any more. You do not have to let nature take its course. Reclaim you size, your circulation, and your manhood again. If you follow the 15-minute per day regimen, you will see results quickly, and you will not regret your decision to take control of your unit.

PS do yourself the favor of getting the bath strap. I didn’t at first, but ordered one within 2 weeks. Game changer:

I love my penis!

I was skeptical and, after a few days of misuse, was disappointed, but after some additional instruction from customer service, and a couple more weeks of regular use, this pump has turned my dick into a COCK. I can't wait to actually try it out on someone.

Pump to plump

I was skeptical at first but thought I would try Hydro7. From the first use I fell in love with it! The gentle and amazing feeling of the suction had me sold. After a short period of time I was able to notice a difference in girth but the real testament was when my wife mentioned how large I felt! Definitely impressed!

It’s does the job that it was intended for. For my first pump, I am satisfied with it. I think I would like the hydro extreme pump for the ability to maintain the pressure more accurately. But the hydro7 for the cost works well.

Your Hydro questions, answered.

How does the Hydro function?

The Hydro works by using water-based vacuum pressure to safely and effectively increase blood flow to the penis. When filled with warm water and sealed against the body, the pump creates a gentle vacuum that draws blood into the erectile tissue. This process helps improve circulation, support erection strength, and over time, encourage gains in size and stamina.

Who is the Hydro suitable for?

The Hydro7 is ideal for men with a penis length of up to 7 inches when erect. It’s designed for those new to penis pumping who want a safe, effective introduction to hydro-vacuum technology. If you're looking to improve erection quality, boost blood flow, or increase size over time, the Hydro7 offers a solid, user-friendly starting point.

Can I use the Bathmate Hydro in the shower?

Using the Hydro in the shower offers the same performance as in the bath, with added convenience and minimal setup. For even more comfort and hands-free control, pair it with the Bathmate Shower Strap accessory.

Whether you prefer showers or baths, the Hydro fits your lifestyle - delivering consistent results wherever you choose to pump.

What is the recommended usage frequency for the Hydro?

For the best results, use the Hydro once a day for up to 15 minutes, no more than five times per week. This frequency allows your body to recover between sessions while supporting measurable gains in erection strength, blood flow, and size.

Can I achieve permanent results with Hydro?

Regular pumping with the Hydro encourages gradual tissue expansion and improved vascular health, which can lead to lasting improvements in erection quality and size. To maintain and reinforce your gains, continued use is recommended as part of your long-term routine.
