What is the diameter of the top opening and/or has anyone found a metal infuser that fits it?

3 and 1/8" on the teapot and 3" on the infuser. The reason for me to get this teapot was I want a glass only teapot, so I can't answer your question. Metal infuser may be better than a glass infuser, but it definitely decreases the beauty of the teapot.

The diameter of the top opening is approximately 3 1/8", and although I have a metal infuser that fits in it, I have no idea what brand it is.

Yes, very simply pull it out of the top. My model has a soft rubber gasket which holds the infuser in place.

I use mine in a tall 16oz tiger, the tab of the infuser can be bent to a hook shape to hang it.

I have the 48 oz maker and it holds about 45 oz with the infuser in place without over flowing. The infuser really doesn't take up much since it is mostly screen.

It can be used without the infuser but I don't know if the lid will fit as well. Have not tried that.

Mine is 3" tall, diameter at the bottom is 2 1/8", diameter at flare under lip is about 3". I have mugs rather than tea cups and it works with all of them except for one with a 3" diameter rim. The infuser doesn't quite fit at the top. Hope this helps.

No, the entire infuser, including handle, is roughly 3 inches wide (other people may have a more accurate estimate), so I'd think it will be too small.

The infuser is about 3 1/2" across; the lip is about 1/4" across. The height is around 3".

The infuser is six inches tall. It does float in a tall mug. Most likely a little short for your Hydro Flask.

This infuser actually floats to the top of my mug. You should not have any trouble. I use a tall mug myself and I do not have any problems.

Yes. The base of the infuser fits in the lid when it is turned upside down.

I don't know. I had the same pot but with the metal infuser and the pot broke. The metal one worked fine in this one so I never used the plastic one. Sorry. The metal one works great!

The opening is the same diameter as any flask. I recommend an average sized funnel. Don't get anything too big as it will spill if you overflow. Most funnels with a long spout should fit. I don't have exact measurements for anything. Just Google it.

The bottom part of the infuser is 1.75", but the top is 2.375" with a .25" metal rim. It is also 3" deep. I have my doubts about your teapot, but it will fit nicely in the average cup.

I am not sure. This was a present to my son. He did say that the teapot is a good size though. They love it and I know that it serves more than two at a time. I would imagine that it would be worth a try to put an infuser in it. I am thinking the the diameter would be about 2.5 to 3". I have a little smaller teapot (different brand) and I measured it and it is 2.5. I would try the 3".

Yes, it is! that's why I bought this tea pot -- the expensive one I bought at a store didn't sell replacements. Anyway - go to their website sunstea.com and search for "replacement infuser" and find the one for your tea pot

I don't know, but as far as an infuser goes, it's top of the line. It is very good quality, it cleans easily and, in my opinion, it will never wear out. I have bought several, and this is the one for me.
