Jack Bench

An seat often found in an enclosed bathroom shower. The structure is typically built-in and constructed of masonry and tile, or free-standing and made of a sturdy, pressure-treated hard wood. The design reduces stress on the user’s lower back during covert masturbation.

I put an offer on the house as soon as I saw that the shower in the master bathroom featured a jack bench.
