Infinity edge is pretty easy I think. That would be your skimmer too. No fish, no plants but maybe a lily there isn't much to filter. Add a UV to stop green water and the muck it generates. Add a chemical like AlgaeFix to to stop macroalgae and you won't have that muck. I'd be surprised if you had to vacuum it more than once a year, if that. As a reflecting pool it can be very shallow, like a few inches if you wanted, with just a small deeper area for the lily. Then you wouldn't even need a vacuum, a broom would work.

Uhh, ahhh. Really nice. Really nice.

Thank you! It reminded me of Montana. Just showed my DH. We must come visit your lovely state one day. Diana

Yes, I am thinking of two small low back swivel chairs on the mirror wall and another two chairs across placed at an angle and low enough that the backs of the chairs won't obstruct too much of the view at the window and the reflection of the view--with a small wine-like table between each set of chairs. Thanks for reminding me that I should lower the usual height of the mirror--whatever that should be. Now my concern would be all the space between the top of the mirror and the 10' ceiling. I do have a 10" ceiling molding that may help fill the space above the mirror. This is something I hope to consider. Thanks for your help!
