Size guide
1. Get an erection
In order to measure yourself correctly your penis must be in an erect state. This will provide the most accurate method of ensuring you choose the correct pump. You will then be able to select a pump from the four ranges provided.
2. Measure your length
Measure your erect penis with a rule pressed lightly onto your pubic bone. You`ll find using a measuring gauge is easier than a ruler. Record the measurement from the pubic bone right up to the tip of your penis. You will need this measurement later.
3. Measure your girth
Measure your erect penis with a rule pressed lightly around the thickest part of your penis. Again, you`ll find using a measuring gauge is easier than a ruler as it bends with ease. Alternatively use a piece of string to get the circumference and then measure this with a ruler. Record the measurement from the full circumference your penis. Enter your measurements into the calculator to discover your perfect pump.

How Hydromax works
The Hydromax 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 uses the natural force of water to create a controlled vacuum around the penis, increasing blood flow to the erectile tissue. This enhanced circulation encourages the gradual expansion of the penile chambers, resulting in firmer, fuller, and more responsive erections. Consistent use helps improve vascular function and oxygen delivery, supporting your body’s ability to perform at its best without relying on pills or quick fixes. Whether your goal is improved size, better endurance, or a serious confidence upgrade, Bathmate is designed to work with your body - not against it - for real, lasting results.
How to use
Bathmate is designed to easily integrate into your daily shower or bath routine. Fill the device with warm water, insert your flaccid penis, and draw the pump inward to form a vacuum seal. Hold the pressure for up to 3 minutes before releasing, then repeat the process up to three times - keeping your total session under 15 minutes. Finish with a brief massage to help the tissue relax and recover. When followed consistently, this routine supports noticeable improvements in erection strength, size, and overall confidence. It’s straightforward, effective, and built for real results.
Is it safe?
Bathmate delivers a secure experience when operated as instructed. Its water-based system applies uniform, controlled pressure around the penis - minimizing injury risk and enhancing comfort compared to air pumps. Every Bathmate device is FDA-registered and engineered with built-in safety measures such as pressure-release valves and ergonomic seals. Adhere to the 15-minute session limit, up to five times weekly, to achieve optimal performance without overuse. Tried and trusted by over a million men, Bathmate combines safety and effectiveness for confidence you can count on.
Expected results
When used regularly, Bathmate produces noticeable and trackable improvements. From the very first session, users often experience a temporary boost in size and firmness due to enhanced blood flow. As the weeks progress, your body starts adapting - resulting in stronger, more dependable erections and improved endurance. By the 8 to 12-week mark, many report visible enhancements in both girth and length, along with greater sexual confidence. Continue past week 16, and those gains tend to solidify. Whether you’re aiming for performance, power, or presence, Bathmate supports your progress - naturally and reliably.

Your Hydromax questions, answered.
Is the Hydromax suitable for my size?
Yes - Hydromax pumps come in multiple sizes to fit a wide range of penis lengths and girths. Whether you're just starting out or looking for more room to grow, there's a Hydromax model that’s right for your body. Use our size guide to choose the perfect fit for optimal pressure, comfort, and penis pump performance. A snug, correct fit is key to getting the most out of every session.
How often should I use Hydromax for the best results?
For best results, use your Hydromax penis pump once per day for up to 15 minutes, no more than 5 days a week. This frequency allows your body to adapt safely while supporting long-term gains in erection quality, stamina, and potential size increases. Following a consistent Hydromax routine is key - regular use delivers the most noticeable results in blood flow, vascular health, and overall sexual performance.
How long will the benefits from using Hydromax last?
Short-term effects - such as increased fullness and blood flow - can last several hours after each session. With consistent use (up to 15 minutes a day, 5 days a week), you can expect more permanent improvements in erection strength, stamina, and size over time. To maintain your Hydromax results, ongoing use is recommended. Think of it like fitness - the more consistent you are, the more lasting the benefits.
What makes Hydromax better than other penis pumps?
Hydromax uses patented hydro-vacuum technology to deliver safer, more consistent pressure than traditional air-based pumps. This water-based system evenly distributes pressure around the penis, reducing the risk of injury while maximizing comfort and effectiveness. With a high-quality bellows system, comfort pads, and multiple size options, Hydromax is designed for real results, safety, and ease of use. It’s one of the most trusted and clinically tested penis pumps in the world.
Can Hydromax help with erectile dysfunction (ED)?
Yes, Hydromax can support men dealing with mild to moderate erectile dysfunction. By using water pressure to increase blood flow to the penis, the Hydromax pump helps promote stronger, more reliable erections. Over time, regular use can improve vascular function and responsiveness, making it a natural, non-invasive solution for improving erection quality without relying on medication. Many users report noticeable improvements in ED symptoms within weeks of consistent use.
How do I clean and maintain my Hydromax pump?
Cleaning your Hydromax is quick and easy. After each use, rinse the pump thoroughly with warm water and a mild, non-abrasive soap. For a deeper clean, use the Bathmate Cleaning Kit or a suitable antibacterial sex toy cleaner. Make sure all parts are fully dry before storing. Regular cleaning prevents buildup of bacteria and keeps your pump performing at its best - ensuring safe, hygienic, and effective sessions every time.
