Ancient City Sauna Idea

The Ancient City Sauna is a really interesting piece to the entire structure as a whole and adds a lot of lore, but I recommend only a mini cosmetic change. I would love to see the larger pool have the the ground beneath it be magma blocks to make mini bubble columns in the pool to really look like a sauna. Then in the smaller pool on the opposite side of the structure can have soul sand underneath it to have the other type of bubble column effect to kind of hint to new players that soul sand can be used like the magma blocks!
