The water material you need for your arch viz

No need to even unwrap, just adjust scale and boom! Your scene looks nice already with almost no memory consumption and fast processing.

Add this pleasing look for your animations and images👇🏻

What you will get is a zip file with caustics folder and blend file including water material in a demo pool with a fairly set render settings

in some scenes you may need to increase clamping range more than 20 to have caustics visible , you may also need to relink caustics folder 

Works best with Cycles

Blender 3.2 caustics is good , but it is still a bit boring to setup and yet it makes your pc cry for help (at least for now 😁) 
so for water it is better to use this fine material to save your day , but anything else needs real caustics to shine
