The Submarine Waterproof Masturbator: An Honest Look From Someone Who's Handled a Lot of These
We've sold a lot of strokers over the years. Cheap ones, fancy ones, ones that looked great in photos and fell apart in a month. So when the Submarine Waterproof Masturbator landed on our shelves and started getting repeat customers, I paid attention. This is a $140.59 device, which puts it in the "think about it first" category for most people. So let me give you the rundown you'd get if you walked into our shop and asked me straight.
Let's start with what it's actually made of, because this is where a lot of expensive toys cut corners. The Submarine uses body-safe silicone for the sleeve and a hard ABS shell on the outside. That combination matters more than people realize. The silicone is soft and stretchy enough to feel like skin against you, but the rigid outer casing means the thrusting mechanism has something solid to work against. If the whole thing were soft, the motion would just flop around. The internal sleeve has a textured channel that runs the full length, and the seams and finish on the unit I inspected were clean — no sharp edges, no chemical smell out of the box, which is not something I can say about every product in this price range. Build quality overall feels dense and solid. It doesn't rattle when you shake it, and the buttons have a firm click to them. That sounds like a small thing until you own a toy with mushy buttons that trigger the wrong setting mid-session.
On specs: the Submarine measures roughly 10.6 inches in total length, with an insertable channel of about 7.1 inches and an internal diameter around 1.4 inches, which stretches comfortably thanks to the silicone. It's a standard-size unit — we don't carry a wide range of sizing on this model, and honestly, most guys fall within it fine. Weight is close to 2.4 pounds, which is heavy enough that you'll notice it in hand but not so heavy it's tiring. It charges via USB-C and gives you about 90 minutes of use per full charge depending on which modes you're running. Colors vary by batch, so check the product page for what's currently in stock. Every unit ships under SKU P3256811362599422 — that's the code you'll want if you need to contact us about a specific order or replacement part, so copy it down when you buy.
So what do you actually use this for in daily life? Three real scenarios come up over and over with our customers. First, the shower and bath. The IPX7 waterproof rating means you can fully submerge this thing, not just splash it. One customer told me he takes it in the tub after long shifts because the warm water plus the thrusting mode is the fastest way he's found to unwind. Second, solo sessions where a hand just isn't cutting it anymore — the 360° contraction and vibration modes give you a layered sensation that you genuinely cannot replicate manually, and for guys who've built up a tolerance to standard strokers, this is the upgrade that resets things. Third, couples use it. Not as a replacement for anything, but as a warm-up tool or something one partner operates on the other. We get a surprising number of questions about that, and the answer is yes, it works fine for that with a bit of coordination.
Using it is straightforward. Charge it fully first — don't skip that, the motor runs weak on partial charge and you'll think it's defective. Add a decent water-based lubricant inside the sleeve. Silicone-based lube will degrade the silicone sleeve over time, so stick with water-based even if you prefer the other. Cycle through the thrusting, contraction, and vibration settings one at a time until you find your combination. Cleaning matters: after every use, remove the sleeve if your model allows, rinse with warm water and mild toy cleaner, and let it air dry completely before storing. If you skip the drying step, you'll get mildew, and once that sets in the sleeve is done. The outer shell wipes down with a damp cloth. Don't submerge the charging port cover area while it's open, obviously, even though the unit is waterproof when sealed.
Now the honest part. Pros: the multi-mode stimulation is legitimately varied and not just three settings that feel identical. The waterproofing is real, the battery life is respectable, and the build quality justifies a good chunk of the price. Cons: it's loud. Not deafening, but on the highest thrusting setting you'll hear it through a closed door, so keep that in mind if privacy is thin at your place. It's also heavy for extended use, and at $140.59 it's an investment — if you're brand new to powered toys, I'd honestly suggest starting cheaper and working up. Finally, the sleeve isn't user-replaceable on every batch, so check before you buy if long-term maintenance is a concern for you.
Here's why this design works, from someone who's watched the category evolve. Older strokers gave you vibration and called it a day. The Submarine adds a thrusting motor on a separate axis from the contraction ring, and that layering is the whole trick — your body reads the combination as more lifelike because the sensations aren't synced perfectly. It suits guys who've owned a basic stroker and want more, people who specifically want shower-friendly use, and anyone who values a solid build over a cheap disposable. It does not suit first-timers on a tight budget, light sleepers with roommates, or anyone who wants something silent.
