Finally got a chance to clean the room out. Floor is in good shape. The trough is conncrete on the bottom. The only drain that works (there are 4) is the drain in the bottom of the trough. It shouldnt be a problem to fix the others though.
From the front door
from the back
Had one small setback though. The roof is leaking a little and rotted a few boards out of the ceiling. Which, btw is 4" tongue in grove. i think you can see some of it in the picture The stuff has probably been there 50 years and was in great shape except for those few pieces. So, i had one of my guys go in to remove the rotten boards to fix the leak. Well evidently he misunderstood and removed and burned the ENTIRE ceiling.
that stuff is crazy expensive. So now i may be down to a cheap plywood.
So tommorow ill start back on getting the water ran in the room and start planning where im gonna put everything. I need to get the design layout so i can decide where to run the water lines and electric. Ill probably put a grate over the trough so it still drains but i can walk over it
