Trying to find source of leak. Leaks when showering. Guessing its rusted or cracked in the integral drain. Does that ever happen? When it dries I will test by running water into the drain without using the shower hose.
Not seeing loose grout or caulking -- the bezels on the faucet handles are not sealed, but they don't get sprayed continuously. A while back I had to re-grout the soap dish/grab handle, it was leaking a lot more from that gap. I will caulk the bezels.
There is a hole in the plywood flooring on the near side of the drain piping, I can stick a mirror & light in to look around a little bit. The top of the flooring is wet & it spreads to certain areas, then drips down in certain places.
Tub overflow line feels dry, & would not be a continous source of water.
I cannot see the shower riser. Its copper, could have a pinhole. But cannot confirm water flows from there along the top of the sheathing.
Cannot see the valve set either. 3 valve type, 1966. Could have erosion leak ???
I can see & feel wetness UNDER the tub
The cold water riser goes up on the far side of the center joist & the sheathing at the hole is wet -- but that would give a continuous leak problem, not just when using the tub. Could be flowing there from elsewhere.
The gasketed drain area is partly over a joist & sheathing. It rests on the sheathing -- should the center (keel) of the tub make contact? Or only the outside edges of the tub? What are the load bearing areas?
The portion of the bowl which I can see is half an inch above the flooring, but cannot see the central "keel" area.
I want to cut away the sheathing at ccccc and around cw so I can see more of the drain & maybe under the tub on that side. But its narrow, the distance between joist & stairs, & I have to reach sideways.
O = drain at gasket as visible from below. Actually larger diameter.
0 = short horizontal run - is this cast into the tub ? I can't see it.
D = drain opening as seen from top of tub.
o = horizontal drain pipe.
| = seam between two sheets of plywood. Seeps thru here but not the main leak point.
.... = plywood sheathing/flooring.
cw = cold water supply riser.
222 = 2x4 on edge between joists, above plywood. Seems to be there to support the hot water line. Or to prevent joist from twisting due to load?
2h2 = point where hot water supply rises upwards thru it. Not wet above, but major leak is thru hole. Must be horizontal gravity flow towards it. Only drips when running tub water, so its not a pinhole in the pipe.
hhhh = horizontal run of hot water line. This and the ooo drain line are somewhat above each other, so dripping water can run along it or both; the area LLL edge of sheathing at the cutaway area might also be where its coming down from.

The far side is a double joist -- but its also got the basement stairs on the other side so I don't know if the double joist is to bear the load of the tub or just the way the stairs were built. Both bathtubs are "in line" so the two tubs are above the same joists.
There is a single joist just beyond the near edge of the tub (the vertical edge, not the "bowl").
