Bathmate HydroXtreme 11 - XL hydro pump - clear

Bathmate HydroXtreme 11 - the largest model in Bathmate’s premium “Just Add Water” HydroXtreme range, specifically designed for men with a larger erect penis size (23-28 cm / 9-11 inches). The patented hydraulic vacuum technology plus the included handball pump together provide one of the most effective penis enlargement systems in the industry.

What is Bathmate “Just Add Water” technology?

Bathmate (United Kingdom) is the industry’s first and leading manufacturer of hydraulic (water-based) penis pumps. While traditional “air pump” penis pumps create uneven pressure and can often cause injury, the Bathmate “Just Add Water” system uses water as a transfer medium - this delivers even pressure along the entire length of the penis, dramatically reducing the risk of injury.

Differences between Bathmate ranges - Hydromax vs HydroXtreme

Who is the HydroXtreme 11 specifically for?

• Men with a larger penis size: 23-28 cm (9-11") erect length - this is the largest Bathmate model.
• Experienced users: the handball pump allows more precise, higher vacuum - for advanced use.
• Those aiming for maximum results: the HydroXtreme system is the most effective in the Bathmate portfolio.
• Fans of hands‑free use: with the included Shower Strap you don’t even need to hold it in the shower.
• Comfort‑oriented buyers: the comfort insert reduces discomfort during longer sessions.

4 main functions / benefits

• Handball pump included: the red‑tubed handball pump delivers a more precise, higher and more controllable vacuum than bellows pumping alone. Your hand tires less and the pressure can be finely adjusted.
• Water‑powered hydraulic system: even pressure over the whole penis - it doesn’t concentrate on one point (a common cause of injury with air‑vacuum pumps).
• Internal scale / measuring gauge: built‑in cm/inch measuring scale on the cylinder - to record visible gains.
• “X‑Seal” soft comfort collar: skin‑friendly, hypoallergenic TPE inner collar - reduces discomfort at the entry area.

Regular use - expected results (according to Bathmate’s official communication)

• Immediately (after one session): noticeable increase in length and girth (temporary, lasting a few hours).
• After 4-6 weeks: measurable, lasting gains with regular protocol.
• After 6 months of regular use: up to 2.5-3 cm in length and 30-40% increase in girth.
• Bonus effects: harder, longer‑lasting erections (improved blood circulation), better erection quality, increased self‑confidence.

WARNING: results may vary from person to person. Bathmate does not guarantee the values mentioned - these are average user experiences.

How to use it - step by step

• Step 1 - Warm‑up: take a warm shower (5-10 minutes) focusing on the groin - it is worth “preparing” the penis before use.
• Step 2 - Filling the pump: completely fill the cylinder with warm (NOT hot!) water so that no air bubbles remain.
• Step 3 - Insertion: press the cylinder onto the penis so that the comfort collar sits snugly against the pubic area. DO NOT let the scrotum get inside!
• Step 4 - Vacuum: press the bellows several times, or use the handball pump for higher vacuum.
• Step 5 - Hold: maintain the vacuum for 5 minutes, then release (open the valve at the top), and pump again.
• Step 6 - Duration: total session 15-20 minutes (3 × 5‑minute cycles, or 1 × 15 minutes).
• Step 7 - Release: press the red valve at the top to release the vacuum, then remove the pump.
• Step 8 - Cleaning: rinse immediately after use with lukewarm soapy water.

Protocol - 6‑week programme

• Week 1: 3 sessions per week, 5-10‑minute sessions (low vacuum).
• Weeks 2-3: 4-5 sessions per week, 10-15‑minute sessions (medium vacuum).
• Weeks 4-6: 5 sessions per week, 15-20‑minute sessions (maximum vacuum that is still comfortable for the user).
• Rest day: at least 1 rest day per week.
• Recovery day: once a week you may skip pumping to allow the tissue to regenerate.

Points to pay particular attention to

• WARNING - size validation: the HydroXtreme 11 is the LARGEST model. If your erect penis is shorter than 23 cm (9"), a smaller HydroXtreme model (5, 7, 9) is more suitable. An over‑sized pump = ineffective use.
• Risk of overuse: max. 20 minutes per session, max. 5 sessions per week. More = risk of injury (burst blood vessels, purple marks).
• Do NOT allow the scrotum into the cylinder! Risk of serious injury.
• Penis turning purple or grey? IMMEDIATELY release the vacuum - pressure is too high, risk of burst blood vessels.
• Do NOT use: under the influence of alcohol / drugs, with heart disease / blood pressure problems / blood‑thinning medication, or after surgery.
• Use water‑based lubricant only - silicone‑based lubricants damage the TPE collar.
• Cleaning: lukewarm soapy water or a special toy cleaner (e.g. Toy Cleaner 8718627520062, available separately). Do NOT use washing‑up liquid (it damages the polycarbonate).
• Storage: in a cool, dry place, free from moisture (risk of mould).
