I think some people use heavy duty velcro inside a tank. I have used bottle stands but they can tip over a bit as well and be a fiddle. Living world make one to fit their bottle, if you like that bottle - I could never get on with it and worried in case it got knocked over and hurt the hammy! It's quite big and heavy. I like the Ferplast drinky mouse sized bottles - they always seem to let water out well and not drip. Although I'm so paranoid about them letting water out I used to leave it slightly unscrewed and then it did drip a tiny bit. The classic mouse bottles are popular too. They'd probably need to be stuck on with velcro. It's quite effective but maybe doesn't look so glamorous!
I did have a Rodipet water bottle stand that holds the classic mouse bottles - it was a bit of an extravagance. Very nice but placing it was always tricky. It's better on something flat and firm like a house roof or shelf - but it won't fit on them as then it's too tall! So I also had the granite square from Rodipet and stood it on that which worked well except I then worried our hammy would tunnel under it and the granite fall on him and hurt him. I gave up with having a bottle stand eventually - I think it's easier having them on the side of the tank/cage.
I would think in the Marrakesch you would be having the substrate reasonably deep in most places so not easy to stand a bottle stand on as well.
I whinge about bottles - they're a pain. I do like the Ferplast Drinkys though. The bar clip they come with wouldn't be much use in the tank, but they're not too expensive. I used to get two at a time to save on postage and have a spare. Haven't found them easily available anywhere else.

You can make a water bottle stand - there are various suggestions around. I like the one where you cut the top of a small mineral water bottle, so you're left with the long straight bit. You put stones (cleaned) in the bottom to weigh it down and keep it stable and make a hole in one side at the right height for the bottle spout to go through. But they can still get knocked over lol.
