Thirsti 48oz Removable Water Reservoir

I use the extra reservoir with my Ninja Thirsti system, and it’s been a game-changer. I don’t have to stop mid-day to refill or wait for water to chill—it’s just there, ready. What I love: The 48 oz size means I’ve got plenty of cold water on hand. Amazon +1 The leak-proof lid both standing and on its side gives me peace of mind in the fridge. Amazon The “cold water indicator” that turns blue when it’s at just the right temperature is a neat little bonus. Amazon It fits nicely with the Thirsti system (just make sure you have the compatible model). My “why it matters” summary: If you already have the Ninja Thirsti, adding this extra reservoir means less downtime. More hydration, less fuss. No thinking about “oh, I should refill later” or “why is the water warm now?” It’s ready. One small note: Make sure you’ve got space in your fridge for it. The size is generous, so clearance matters. It’s designed for the Thirsti system only—double-check compatibility before buying. Bottom line: If you’re using the Ninja Thirsti setup, this extra reservoir is well worth it. It gives you a second stream of cold water without the hassle of stopping to refill. A smart, simple upgrade.

Multiple people in my house use the Thirsti, and it happens at least twice weekly that someone forgets to put the tank back in the fridge, usually me. But now I don’t have to get yelled at because there’s always a spare in the fridge. I didn’t “need” this, but it’s pretty inexpensive and saves me some hassle.

This reservoir worked great as a replacement for our mistakenly broken one. It fits just like the original. Super easy to use with no weird aftertaste.

Works great as a replacement, my original got placed in the freezer and cracked.

The cost was cheaper than I thought it would be. 20 bucks and I have a standby in the fridge.

Does what it says exact match needed.

How this was great my kids drain the other one when they make their drinks and then forget to fill it back up so we always have a backup now this was a perfect gift for my wife

Sometimes it fell off and big spill in the refrigerator. the bottom edge can till it in the refrigerator wire like shelves. some times will fall even on the drain board just bump very lightly.
