About the Goliath


Boasting the same, high quality build quality as its predecessors, the Goliath is 30% larger than its smaller sibling, the Bathmate Hercules. Conceived due to the demand from existing customers and male porn stars wanting a quality penis pump that could take their penis size to the next level, the Goliath was born and has the ability to make you even bigger!

About the Hercules

The Hercules is the original Bathmate device and was launched over 5 years ago, yet still remains the most popular penis pump on the market today.

With more than 200,000 satisfied users and now available to purchase in more than 60 countries across the world, this classic Bathmate has a reputation built on being easy and convenient to use whilst importantly consistently providing genuine gains in both length and girth.

Due to the slightly longer and wider gaiter and pump cylinder, the Goliath is marginally heavier and weighs in at 330g. Despite the marginally higher weight, the Goliath still uses the same highly durable polycarbonate plastic for the cylinder and skin safe rubber for the gaiter whilst maintaining exactly the same level of achievable air and water vacuum as smaller models.

The Hercules is a sealed, one piece system making the device incredibly easy to use and clean. The premium gaiter is designed for comfort, durability and enhanced suction whilst the Hercules cylinder includes a handy measurement guide along with a simple, safe and easy to use pressure release located at the end of the device. This leading penis enlargement pump can be used in the bath or the shower and although we recommend use of water for optimum comfort and results, this device can be used without if desired.

The Bathmate Goliath can accommodate a maximum girth of 2.56 inches and a maximum length of 10.24 inches hence is recommended to those looking to achieve a maximum erect length of a little over 10 inches. If you already have a big penis or have reached the limits of your existing Bathmate device, now’s the time to upgrade to the Bathmate Goliath model.

The Bathmate Hercules can accommodate a maximum girth of 46 millimetres (1.81″) and a maximum length of 180 millimetres (7.08″) hence is recommended to those with a starting size of 5-6 inches or less. If you already exceed 6 inches in erect length, we could recommend the purchase of the Hydromax X40 or the Goliath model.
