near toilet floor constantly wet

More pictures all around toilet.

There's a commonly overlooked source: condensation. If the relative humidity is high enough — unlikely in the winter, but not impossible — condensation can form on the tank from the cold water coming in and then drip down on the floor. I've had that happen.

Specific Men / Boys using the toilet a lot?

Is the house on a slab? Looks like an under floor leak. It looks dry around the toilet .

@azward take pictures of the underside of the tank where it bolts to the bowl. Take pictures of both sides, clearly showing the bolts sticking out.

Water inlet

You need to look under the tank

36% at 70F is a dew point of around 40, so even really cold water probably wouldn't cause much if any condensation.

I'd take pictures with my phone my self. I don't like reaching under toilets blindly. 😉

agree although I use toilet papers, readily available and show wet spots quicker.

is there a drop coming off the bottom of that loop on the supply line? it is either coming from there or inside the wall to the right

Replace the supple line. Get one the right length. Friend flooded her whole house when that white nut cracked. Rust and deposits, leaking for a while.

since you don't see any leaks from above, my next steps would be to pull the toilet and see if the wax ring had failed. If it had, great you found your problem. Clean the flange and toilet base and redo. If not, it's time to start thinking about what's in the wall behind

Changing the wax ring is a 15 minute job unless it's your first one. I stock several different thicknesses of wax ring and a non-wax seal or two so I don't spend a lot of time running for parts. If you don't know what you need you will have a run to the hardware store after you take it off. To me, what I see in the pictures had me thinking wax ring immediately. If you get one of those non-wax seals, while they are more expensive, they are easy for someone who isn't familiar with the job to get it right the first time. Just FOLLOW THE INSTRUCTIONS on the box.

@azward It appears that you have tile and grout there. Water follows grout lines, it doesn't permeate a glazed tile and so the tile doesn't look wet. Unless the seal has failed catastrophically there's only a little water leaking at each flush and it follows the grout lines as the path of least resistance, it won't necessarily flood out over the surface of the tiles. Back when I was on a maintenance crew and saw situations like your picture shows I did the "wet finger" test underneath the tank and checked the supply line for leaks but it usually was the wax ring.

Is this the same building as your other post? If this was on a slab I'd have guessed a leak in the slab floor soaking through the mortar. But I would guess there is a leak in the wall behind the toilet.

since it is in your own home you can dry things up and make a barrier on the floor to figure out where it is coming from. this would be more difficult for a professional that would only be there a couple hours trying to track it down

It's not uncommon for the shower valve to leak. Not sure what kind of valve you have but I'd check there first. It's the easiest to check and repair.

the handles for the shower controls need to be sealed one way or another to keep water splashed on it from running inside the wall, either by the valve body being sealed to the tile or by the cover being sealed to the tile. a lot of less than competent installers miss this. it could also be failure of the shower pan or the tile.

it depends on what kind of shower pan it is. if it is a formed fiberglass pan then any leak is likely from somewhere up higher unless it is cracked or the drain is loose. they were thinking of a tile shower floor with a copper, pvc, lead, or hot mopped tar pan under it.

I guess there's cheap toilets, and they are usually less than great.

Then there's decent toilets, and they aren't exactly cheap and then there's really good toilets…..

I'd expect to pay $400-800 for a decent toilet with tax etc.

My problem with pulling a toilet is I know without a doubt I'm not going to be happy with what's under it and it turns into a whole day ordeal.

I had a really weird one once — a flush valve (antique!) which sprayed a little water onto the tank lid. Which then flowed along the lid to the rim of the lid outside the tank itself, and then dripped onto the floor behind the toilet, but not right away when you flushed.

Took a while to track that one down…
