Actually, the link i gave you for the syrial @ JandRhookahs is the one that disasembles and is height adjustable. I was , once again, admiring those syrians at Jimmys site and i came across the image og that hookah disasembled. here is the link
Note: It's the "etched stem" one that disassembles not the carved
As you can see you can skip one or two pieces from the stem and make it a 24-25 inch hookah.
That blue genie is my next hookah. Keep them stocked jimmy xD
I hope i've helped you, Bustinx
