BathShroom BTHSH620 Overflow Drain Cover for Fuller and Warmer Baths, White

It really works! Easy to use. The suction keeps it on , almost hard to get off. I lost no water in my soaking tub. In fact, the water was up probably 4 inches higher, using this suction cup. One size fits all. Good quality.

Makes all the difference in the bathtub, adds inches to water level. Easy to install and remove

Not using this for exactly the product's original purpose (covering touch controls from getting activated by a damp shower curtain), but it works quite well for what I needed. There's around a dozen little suction cups around the rim, and if you're careful to press each of them individually you'll get a pretty solid seal. In an only mildly damp environment without significant additional pressure (from, say, bath water) it can last a good week or so before coming unstuck. Ideally it wouldn't come unstuck at all without manual intervention, but I'm pleased with the quality nonetheless

This works very well. I had one by a different company but it was tough to get it to stick. The suction cups on this one are better designed - they attach and release much easier!

Proving you can find ANYTHING on Amazon, this little item is truly a god send to me! When I set out to see if a tub drain overflow cover even existed to prevent my bath water from constantly needing to be refilled, I was amazed to find this handy product and bought it immediately. I have a white porcelain tub so I selected this simple and clean version instead of the colorful kiddie looking items that are also on sale. It looked quite alien when it arrived and is larger than it appears in the pix. But all you do is start the water, wet this a little bit, press to stick it tightly over your drain do what you do, et voila! A deep soaking experience awaits. I've added a full four inches and the level rests about two inches from the top the tub. Water will flow down from the top of this cover so you can still splash a bit and be safe from overflow. Yes it keeps it warmer longer, brings level over my shoulders and neck (with scrunching) and greatly reduces how many times I refill. A really simple pleasure that adds a lot of luxury to the bathroom. Yes!!!

First it will stain and scum build up shows so easily, not to mention that it grows mold with the greatest of ease. Second it doesn’t really make a seal. The little suction cups don’t hold all that well or tight, and it won’t stay in for a full bath. Just not impressed with the functionality of this for its price point.

This really works great. I don't have to keep refilling the tub

Could not use this. If you have an overflow with a lever on it to close the drain (like the one pictured) there is no way to make this fit. Believe me, I tried raising, lowering, shifting every which way and it never fit snugly enough not to leak. Disappointing. Addendum: that drain on the fixture with the lever runs along the bottom of it: a narrow slit maybe 2 or 3 inches in length. In desperation I rolled about half of a small paper towel sheet into a tight cylinder perhaps 6 inches long and maybe the width of a skinny French fry, moistened it and stuffed it into the drain (with about an inch sticking out on each side) and as the water rose the piece of towel swelled and plugged it perfectly! No leaks at all through a lengthy bath. And later it was easily removed! If you want to try this make sure it is a good, sturdy paper towel (no napkin or tissue or the cheap brand that shreds) and make sure you leave at least an inch protruding so you can easily remove it when done. You can probably adapt this to most overflow drains. I am totally NOT responsible if you are not careful and get it stuck in the drain hole! Anyhow, I am happy now, no thanks to the Shroom.
