There is a stairway leading out of the murky waters on the other side of the room.

Vodin is drenched in water, and he retrieves some of his arrows before heading across the murky water to the stairs on the other side. 

Glink flies across much like the last time, keeping watch for signs of trouble.

Perception 11

At the top of the short staircase are a pair of unadorned bronze doors.

Those that are walking need to make DC 13 DEX saves to avoid falling into an unseen deep section.

Swimming across the deep section shouldn't be too difficult but you would be covered in mucky water.

Nib DEX Save: 16

Nib keeps an eye out for his friends that may need a hand if they slip. 

Semnande is grace incarnate.

Vodin foots begins to sink deeper that he thought, and he quickly pulls back his leg in time and just swim across as he is already wet. 

He then tries to open the bronze doors. 

The next hall way is 10 feet wide and very humid. Water trickles down the walls and drips from the ceiling. There is a narrow stream a few inches wide of warm water flowing down the center of the hallway.

It goes straight for 10 feet then turns to the right. It continues further for another 50 feet or so, then turns right again.

"Where is all this water coming from? Are we below some river or lake? Well let's keep going" says Vodin as he cautiously moves down the hallway keeping an eye out for danger. 

Perception 

21 - rolled in game log

You come to a pair of closed bronze doors, bulging towards you. water is leaking from the edges of the door. You can feel warmth coming from the doors.

Vodin backs away from the door "Watch out. It looks like whatever is beyond this door is filled with water. Should I open the door? It may be our only way out though we still have not checked the other stairway" 

Nib will ready himself by the door

“Yeah sure Bud, go ahead and open it,” Glink answers semi-sarcastically as he slowly backs away from the door.

Vodin will open the door bracing himself for the water. 

Semnande stands just behind Vodin, prepared to leap into battle again.

With a tug and a tug the doors burst open and a tidal wave of hot water explodes down the corridor!

DC 15 STR save or be knocked off your feet and take 12 bludgeoning damage. Even if you are flying you can still be hit.

If you are knocked off your feet, you are dunked into the deep end in the murky slime room.

OOC: I imagine it would have an effect similar to this (but without all the guns and stuff):

Glink slowly rises from the murky water after being swept away, his armor dented and covered in slime.

“How about that rest now Bud?

Strength Saving Throw: 19

Semnande steels himself, getting close to the door and taking hold of the wall as the worst of the deluge blasts past him.
