In your picture I can see nails in the plywood. They go into the
floor joists. I also see they are on 16" centers. What we need to
know is what the joists are resting on. One end should be on an
outside wall.... the other end is probably on a load bearing wall on
the first floor. You need to measure between the two.

Since your house was built in '84, the framing should be ok. But, it's still a good idea to double check. So you can measure the joist spacing as 12 penny said. The span should be from an outside wall to a center beam. You should be able to figure where the center beam is. Then measure that.

The other factor is the size of the joists. If the space under this room has a finished ceiling, no problem. Drill a small hole in the subfloor. Stick a stiff object into the hole to measure the distance to the drywall ceiling below. Stiff wire or a rod or dowel works, fine. Mark the distance and allow for the thickness of the subfloor. That measurement will probably be 7.25" or 9.25 for 2x8 or 2x10 joists.

Report back with the 3 details.

Ah....you forgot the room is on the 2nd floor..... Please stop drinking your lunch!

Floor registers are in every bathroom I've seen around here. But then again, I'm in Canada where we need a little heat in the john.

The OP can use the register hole to see how thick the plywood is and he can likely slide a ruler between the vent duct and the plywood to measure the depth of the floor cavity.

Really a bathroom that small and you need to know all that. The species of the floor joists, the span of the beams, does the word overkill come to mind. I mean if you were doing a 30'x30' floor I could see it.

The size of the room has nothing to do with if the joists are stiff enough for tiles. Unless your idea is that since it's a small room who cares if the floor may fail.

The minimum spec for deflection in non-sleeping rooms is L360. The max deflection for ceramic/porcelain is also L360. That figure does not change when the room is smaller. 2x5 closet or 13x24 room, it's the same if over the same framing.

And yes, doing it right does seem like overkill to some people.

Update, I was able to measure the thickness of the subfloor right next the floor register it is 3/4, that was easy .... Now I drilled a small hole in the plywood a stuck a stiff wire down in until it stopped. it came back at 20 1/4.. So if I deduct the the 3/4 inch from that it is really 19 1/2 inch from the bottom of the subfloor to the top of the ceiling below..right ??? Seems like a lot of space. Still kind of confused on measuring the joist spacing.. I'm just really green to this kind of stuff.....

Well.....something's wrong. There must be a void there, might be over an angled area. What's directly below that spot? Try measuring someplace else.

I still think you're good, but if you're curious.........

Well, if you're really green and don't think you can do it, then you probably shouldn't attempt this....maybe.

But, we're willing to help if you wanna.

Alright after much debate with the wife I have a professional coming over tonight to give an estimate. Talking to him sounds like he knows what he's doing because I was asking about his process and comparing to here. He highly recommended the kerdi system "which is what I knew I wanted in the first place". He also said "I need to see whats under the floor"........ What could he possibly mean .. So i'll post back after the meeting tonight and let you guys know how it went.

Thanks for all the advise !!!!

Perfect!

I don't remember about a shower though, I thought you were only talking about the floor.

Of course....who does only the floor?

If this tile setter uses Kerdi, he is heads n shoulders above most others! Give us details.

Well my tile guy had to cancel for the 2nd time but he had a pretty good reason. He is set up for Monday night so my fingers are crossed. I do have two questions though...

1.. Is there anything wrong with using 1 x 1's for my shower curb ??

2..Does the 32 x 60 kerdi shower pan kit come with kerdi for the walls as well ??
