I am mostly in charge of design and construction observation of a bathroom addition for our gun club. No more Satellites!! I need help remembering the requirements for a CT floor; I don't have access to a TCNA handbook any more now that I'm retired.

The floor is a slab on grade concrete floor. The overall size of the entire addition is 24' x 24' with separate men's and women's bathrooms. The maximum overall dimension of each bathroom is about 11' x 24'. We are planning on using 12 x 12 floor tile. If I'm remembering right, that would be the F113 method, which would be simply a modified thinset directly over the slab? All I can find online is the pictorial for that on the TCNA website. I'm thinking one soft joint at approximately the center of the 24' dimension and a soft joint around the perimeter.

Just as an FYI, we are going floor to ceiling tile on the walls over Dens-shield with a modified thinset. They are talking about an 8 x 8 for the walls.

Any comments from the professionals are greatly appreciated.

Sounds good to me.

I'll second, but add that some gun clubs are one of those places where it may go a few days here and there without any visitors. I'd consider the optional membrane as flashing around the perimeter for waterproofing and as a crack isolation membrane in the field. An overflowing toilet could at least be contained until the calvary arrives.

Thanks for the quick responses. So it sounds like we have a good plan.

BTW, our club has 2 range attendants (club members) on duty from sunrise to sunset, 7 days a week. All members have to do a minimum of 2 range attendant duties per year in order to be a member.

It is a great arrangement. Although it is kind of a PIA to have to do the range attendant duty, I would hate to see what our dues would be if we had to hire it out.

Our club is really good about getting people to volunteer. In fact, about 2/3 of the work on the addition will be volunteers with experience in the areas they are helping with. I and a couple other people will be doing the framing, sheathing and Dens-shield. We are hoping to find some tile setters in the membership. They talked to me about the tile, but I told them that while I have done a lot of residential-size projects, I didn't want to take on something this large. If they talked real nice to me, I might be convinced to help a professional!
