BLAUXPortable Bidet Attachment Tank - 290 mL / 9.8 oz Water Reservoir for Electric Sprayer Bidets | Travel Size, Leakproof, Easy to Clean | Personal Hygiene, Postpartum Essentials

The additional capacity of this tank virtually assures a "one and done" after a bathroom visit, especially when using warm water. Perfect adjunct to the standard unit.

Looking at the portable bidet on Amazon they have an older model that has their triangular symbol on the gold area. Not available. The newer model has the symbol on the gray area. Amazon is selling the 290ml tank for the old model. If you have the symbol on the gray, it will not fit. If the symbol is on the gold, then this is for you. If you are buying the bidet now, this will not fit. There is no void for the charging port on the old 290ml. I thought it was a good idea though.

The Blaux Portable Bidet I possess features the distinguished diamond emblem and seamlessly fits with precision.

The inrease in fluid is good, the threading won't fit the original unit however. Check first to make sure it fits before buying

I LOVE IT!!!!!!! Great attachment. Holds more water for a more difficult situation. I love it. I am glad when I purchased this add on/additional piece.

I know, I know, it's my fault for not reading the reviews first. However: if you ended up buying it only to find out it won't fit after you've already thrown away all the packaging like I did, fear not: the reservoir is still useful! It's not quite as convenient as having a big reservoir that fits on the bidet, but since this reservoir comes with a cap, you can fill it up and put the cap on, then use it as a refill for the smaller reservoir. (Which is why I'm giving it 2 stars - it's useful for something, at least.)

Unfortunately, this extension tank will not fit by with the bow triangular symbol in the gray area. There is no way to know this until you get the tight.
