Waterproof Sex Toys — Hello Nancy Guide

Not all "waterproof" claims are equal. Some toys survive a splash. Others survive a bath. And some die the first time you rinse them under the tap — despite the "IPX7" printed on the box.

If you want a personal massager you can actually take in the shower, use in the bath, and clean properly afterward, you need to understand the difference between marketing and engineering. That is what this guide covers.

Why Waterproofing Matters

If you have only ever used a toy in the bedroom, you are missing half the experience. The shower and bath are two of the most popular places women use personal massagers — and for good reason.

Water adds a completely different sensory dimension. The warmth, the privacy, the steam, the white noise that covers any sound. In our review data, shower and bath use is one of the most frequently mentioned features across 19,000+ verified Lem reviews.

But waterproofing is not just about where you play. It is about hygiene. A truly waterproof toy can be fully submerged and rinsed under running water after every use. No worrying about moisture creeping into seams. No guessing whether you cleaned it thoroughly enough. You rinse it, dry it, and it is ready for next time. For more on this, see our complete cleaning guide.

IPX Ratings Explained: What the Numbers Mean

The IP (Ingress Protection) rating system is an international engineering standard — not a marketing term. Here is what the common ratings mean for personal massagers:

4
Splash Resistant

IPX4

Withstands water splashes from any direction. You can use it near water, but do not submerge. Cleaning is limited to wiping with a damp cloth. Most cheap vibrators fall here — even when they claim "waterproof."

6
Strong Water Jets

IPX6

Handles strong jets of water from any direction. Safe to rinse under a tap or showerhead. Still not safe to submerge in a bath. A meaningful step up, but not full waterproofing.

The difference between IPX4 and IPX7 is the difference between "do not get this wet" and "take it in the bath." When you are shopping for a waterproof vibrator, IPX7 is the rating you need.

The Problem with "Waterproof" Claims

Here is where it gets frustrating. Plenty of products claim IPX7 on the packaging — but the reality does not match.

The Rose Toy is the most prominent example. Many sellers list it as IPX7 waterproof. But search the reviews and you will find a pattern: devices dying after water exposure, charging ports corroding, water seeping into seams. When there is no single manufacturer and the product is assembled across dozens of anonymous factories, quality control on seals and gaskets varies wildly.

This is not just an annoyance — it is wasted money. A toy that claims to be waterproof but fails when exposed to water is a toy you will replace within weeks. And if water gets inside the electronics while you are using it, that is a safety concern.

The issue is not the IPX7 standard itself. The standard is rigorous and well-defined. The issue is that some manufacturers claim the rating without actually engineering their products to meet it. There is no enforcement body checking every product on Amazon.

Tips for Using Toys in Water

Using a waterproof toy in the shower or bath is straightforward, but there are a few practical things worth knowing:

💧

Water-Based Lube Washes Away

Water-based lubricant dissolves in water. You will need to reapply more frequently. For suction toys like the Lem, a small amount on the nozzle rim helps maintain the suction seal.

🧊

Mind Slippery Surfaces

Orgasms in the shower can involve involuntary muscle contractions and weak knees. A non-slip bath mat is not just a safety accessory — it is a pleasure accessory. Plan accordingly.

🌡️

Temperature Enhances Sensation

Warm water makes medical-grade silicone slightly softer and warmer to the touch, which many women find enhances sensation. Just avoid extreme heat — no boiling water.

☀️

Dry Before Storing

IPX7 means water will not damage the toy, but storing it damp in a closed pouch can create a mildew environment. A quick towel-dry after your session is all it takes.

The Cleaning Advantage of Waterproof Toys

A toy rated IPX7 can be held under running water and cleaned thoroughly — every curve, crevice, and around the nozzle opening. Non-waterproof toys require careful surface wiping, and you are always guessing. With the Lem, you simply rinse under warm water with mild soap, and you know it is clean.

This is the best toy I've ever owned! Not only is it fun to use in or out of the shower, it's a nice little something different that I feel leveled up sexy time with my partner.

— Amber S., Verified Buyer
★★★★★

The best suction toy I've ever tried. It has been classified as a shower-only toy. Ifykyk.

— Erin M., Verified Buyer
★★★★★

Quiet and discreet. Gets the job done quickly and efficiently. I shower twice a day and have made it part of my shower routine. Great way to start and end my day!

— Gina, Verified Buyer

I used it in the shower and bath, tried the bed but needed a towel so I think it will be my bath and shower toy only. Can’t wait to explore the other settings.

★★★★★ — Drew B., Verified Buyer

Very quiet and discreet, small but very powerful and can be used in the shower or the bath. We’d recommend this one, the intensity increases as you go through the levels.

Frequently Asked Questions

Is the Lem really waterproof?

Yes. The Lem is IPX7 rated, meaning it is fully submersible in water up to 1 metre for 30 minutes. This is verified and consistent across all units — not a variable claim like some competitors. The sealed magnetic charging port means there are no exposed holes where water can enter.

Can I use the Lem in the bath?

Absolutely. IPX7 means full submersion is safe. Many customers specifically mention using the Lem in the bath as one of their favourite features. The entire body is sealed medical-grade silicone with no seams or exposed ports.

What’s the difference between "water-resistant" and "waterproof"?

Water-resistant (IPX4) means the device can handle splashes but should not be submerged. Waterproof (IPX7) means full submersion up to 1 metre for 30 minutes. For bath and shower use, you need IPX7. Many cheap toys claim "waterproof" but are actually only splash-resistant.

Does water-based lube work in the shower?

Water-based lube washes away in running water, so you will need to reapply more often than you would on dry land. For suction toys, a small amount on the nozzle rim helps maintain the suction seal. Silicone-based lube lasts longer in water but is not compatible with silicone toys — so stick with water-based and reapply as needed.

How do I clean a waterproof toy?

Rinse under warm running water with mild soap or a dedicated toy cleaner. The IPX7 rating means you can be thorough — clean every surface, around the nozzle opening, and any textured areas. Dry completely before storing. For a detailed walkthrough, see our sex toy cleaning guide.

Are cheap waterproof vibrators reliable?

The IPX7 standard is rigorous, but not every product claiming the rating actually meets it. Products from verified manufacturers with consistent quality control (like the Lem) are more reliable than those from anonymous sellers with no traceable supply chain. If a toy costs $15 and claims IPX7, be sceptical — the seals and gaskets required for genuine waterproofing add real manufacturing cost.
