How Does it Work?

Your penis is divided into three chambers – two large ones on top, that’s your erectile tissue (Corpora Cavernosa), and one smaller chamber on the bottom which you urinate and ejaculate from (Corpus Spongiosum).When you get an erection, your brain releases a hormone, which sends blood to your penis, filling your erectile tissue. The blood spaces in the Corpora Cavernosa fill to the maximum, causing an erection. Now the maximum your Corpora Cavernosa can fill is the amount your blood vessels can hold. The great news is…

Your Corpora Cavernosa can be developed larger and stronger with the Bathmate.

The more you use the Bathmate the bigger the vessels become, allowing more blood to flow and fill the tissue. It’s like body building for your penis.

The pump base is designed to allow a minimal compression force, while achieving maximum expansion, encouraging maximum growth and minimum discomfort. The more water is forced from the Bathmate, the more the penis is encouraged to expand and the higher the hydro force vacuum that’s created. There’s always a balance between water pressure, and your penis can not be forced into the unsafe pressure zones that cause damage with other devises.

Conventional air vacuum developers allow the air within to act like a sponge – they compress and expand without enlarging the penis in proportion; this results in the enlargement of certain areas and not others i.e. foreskin and not length or thickness. The Bathmate is filled with water, positioned and sealed at the base. Water is expelled by compressing the Bathmate pump system; this produces the volume and area inside the Bathmate. Balance is achieved for growth.

When compression of the pump stops, the non-return valve closes, thus stopping the water’s return into the Bathmate, Due to the unique pump design, the gaiter expands and tries to return to its original volume, because the water inside the Bathmate acts like a fluid solid, which means it cannot be compressed or expanded, only the penis area can expand to replace the volume of water removed

How to Clean my Bathmate?

Please refer to this cleaning instruction video for detailed information on how to maintain your Bathmate for years to come. 

How do you use it?

1) Fill the bath with water.

2) Once you’re in the bath, put the Bathmate underwater until it completely fills with water, then while it’s underwater put your penis inside it.

3) Push the bathmate down towards the pelvis base several times until you’ve created a vacuum. You should start to feel the pressure building up. Surplus water starts to be replaced from the pressure release valve at the top of the Bathmate. You may have to pump it down four of five times until no more water comes out of the pressure release valve.

4) Once you cannot pump any further, just relax for five minutes. Whenever you cannot pump the Bathmate further this is the optimum vacuum at that particular time.

5) Every four or five minutes try pumping down again. As your penis is expanding this will force excess water from the top of the Bathmate every time you pump down. But you will always reach a point where you cannot pump further.

6) Pump the Bathmate to its optimum vacuum, when you feel it’s necessary. This is the stage where no more water comes out at the end, when you try pumping down.

(7) If you feel the pressure is too much, just lightly activate the pressure release at the top of the Bathmate. This will release pressure. After 15 minutes, release the pressure by pressing the pressure release at the top of the Bathmate and take the unit off. Then stand up so you can see the results right away. You won’t be disappointed.

8) We recommend 15 minutes per session. Use the unit as often as once a day, but no less than three times a week for best results.

What are the main benefits?

Bathmate® has multiple benefits including:

  • Enlarging the length and girth of the penis, increasing confidence and mental health
  • Effectively treating Erectile Dysfunction caused by disorders and prescription drugs
  • Quickly reversing exercise related penile shrinkage and improving sexual relationships
  • Exercising the heart, increasing HDL (good) cholesterol level and overall health

After only ONE session your penis will be noticeably bigger, thicker and heavier. For outstanding results use frequently. Bathmate is the only product in the world using patented hydraulic technology and in our opinion the most effective, comfortable, cost effective and fastest way to get penis growth on the market without expensive overnight surgery. It also can draw freshly oxygenated blood directly into the corpora Cavernosa which maximizes penile fitness. So you can get the best of both worlds with the Bathmate

What are the expected gains?

Generally, most individuals can gain between 1-3 inches in length with a 30% increase in thickness. The increase is in both the erect and flaccid (soft) state. People who are much smaller, flaccid, seem to get the fastest, most noticeable results. You will see results from the first time you use it, the second you take it off. However, your penis will slowly start reducing within a few hours. It’s not an overnight miracle. It’s similar to weight training. If you go to the gym once, your body won’t really look any different, other than pumped for show. Your body is not getting a real change. If you to the gym 3 or 4 times a week you will start seeing changes that stay with you. Bathmate is an exerciser and developer and after only a couple of weeks you’ll really start to notice the difference. The first thing you’ll notice is your thickness and length, the flaccid state will get a lot bigger, as the pressure from the Bathmate opens your Corpora Cavernosa tubes and makes them bigger, i.e. holds more blood. Generally, after between 1 to 3 months, the length will start increasing anywhere from half an inch upwards and the more you use it the fatter and longer your penis will appear

How often do you use it?

We recommend 15 minutes per session. Use the unit as often as once a day, but no less than three times a week for best results. – You’ll be simply amazed at the development in both the erect and flaccid size of your penis, and it can also, psychologically, dramatically improve your performance as well

Bathmate is too small for me

I have now reached the maximum girth using the Hercules model and ring marks have started to appear, but I still have a few centimeters to grow longer. What should I do?

On this page you can read about the larger model, Bathmate Goliath. But before you decide to buy the Goliath, read on:

  • Use low pressure by not putting it into full pressure. This will prevent your penis from filling the girth immediately and allow the penis to stretch lengthwise. The problem with this method is that you will need longer time to grow. However, as long as you do not feel any pain because of the ring marks on the base of your penis or any skin irritation, you should, at the end of the session, pull it to the maximum and make it set for a few minutes. Recommended usage time for this method is 10 min.
  • Use a water-based lubricant that you can buy at any online sex boutique or at your local pharmacy. Use a lot of lubricant as its water dissolvable. Quickly pump to your maximum tolerable pressure and use for the recommended 15 minutes. If water- based lubricant is not an option, you can use oil-based lubricant but then you need to make sure you clean your Bathmate inside and out after every single use. It is more messy and more time consuming.

Can I use it if I’m circumcised?

It makes no difference whether you are circumcised or not.

How effective is bathmate?

The following quotes have been provided by genuine Bathmate® users and are the testament to the effectiveness of Bathmate®:

Testing of the product has shown that if used daily, the product will last for 91.4 years. Based upon a male having a sexual lifetime from ages 18-70, the product will last for 1 ¾ sexual lifetimes.

Tests show that Bathmate® will only begin to malfunction under unnatural forces of above 43kg. The damage that will be done to the product at this force is not permanent damage. At this unnatural pressure there is no damage to the body, valve or any of the adhesions. If the product is ever put under forces of 43kg and above, there should be no risk of the product shattering or breaking and leading to a safety issue for the user.A clinical trial showed that 88% of patients with arteriogenic erective dysfunction had satisfactory results with a vacuum device and had an improvement in their capacity for natural erections.Many studies have been performed on the efficacy of vacuum pumps for the treatment of erectile dysfunction. This is explained in more detail in the further information section in this report.

To date there are no reports of any serious safety issues relating to the use of Bathmate® and the product has never been recalled for any reason.

Are there any safety concerns?

Although this is a safe product, you should make sure that you follow the instructions carefully. It should be stored and kept away from children. You should consult your doctor before using the product if you suffer from any physical penile conditions. Do not use if you have recently had surgery in this area or if you suffer any discomfort prior or after first use.

Penis pumps have been used for years to get excellent results. Pumps are recommended by medical practitioners for Erectile Dysfunction (ED). But check with your doctor. 

Can I use the device in the shower?

Yes you can! The bathmate is just as easy to use at home in the shower as it is in the bath, allowing you to develop your penis whichever way is most convenient.

 1. Shower for a while to loosen up the scrotum.
2. Fill the Bathmate with water from the shower. Hold the bottom of the Bathmate to ensure water does not escape.
 3. Place the penis inside the Bathmate and push towards the body to create an seel. Re-pump if required.
 4. After 15 minutes press the
release valve at the end of the
Bathmate to release.

Are there any side effects?

Yes – and fortunately they are all ones which can bring both you and your partner increased pleasure! As well as resulting in a bigger penis, Bathmate can also enhance your sex drive, increase your staying power and intensify ejaculations

My Bathmate is leaking

No water should leak through the vent on top of Bathmate while its pressurized. The reason for a leak may be that the spring inside the vent is stuck. Advice: Place Bathmate on a flat surface like a table. Pump all air out of it by pressing it quickly against the table, until it sticks to it. You may need to do this several times. If this does not work, please call us and we’ll advice you on replacing the product

How does bathmate treat erectile dysfunction?

Erectile dysfunction affects 80% of men at some time in their lives, however, for some men it is more than an occasional inconvenience. The Bathmate® can help men for whom erectile dysfunction is more than a temporary problem. The Bathmate® mimics the effect that is achieved during a natural erection by drawing blood into the Corpora cavernosa. For those shose blood flow into the penis is an issue, due to vascular problems for example, the Bathmate® can be beneficial. Bathmate® exercises the penis and places blood into the vascular areas of the penis that may not have been able to carry as much blood before. Forcing blood through these veins can make it easier for these veins to carry more blood in the future, which is beneficial to those who have experienced erectile dysfunction due to vascular problems.

After abdominal surgery, often the penis suffers from erectile dysfunction as there is damage from the operation. The body will eventually heal itself, but Bathmate® may speed up the recovery time. Forcing oxygenated blood into the Corpora cavernosa of the penis and through the vascular tissues will speed up the healing process by exercising these tissues. The Bathmate also treats Peyronie’s Disease (bent penis) due to the equal vacuum generated by the water in the pump, which with regular use causes the penis to regain its natural shapeBathmate® is intended to be used on its own, however, at the user’s own risk they may wish to place a medically approved constriction ring at the base of the penis after Bathmate® has drawn blood into the penis. This will hold the blood inside the penis and mimic the effects of an erection. Any constriction device must not be placed upon the body for a length of time greater than 30minutes.
