Tipp.. When drawing a standard bathrm w/5'-0' tub at the back. (we call it a 5x9 in the field)  If the firm you work for calls numbers from the the drywall you have to show that 5x9 at 59" wide after drywall. All 5' tubs come at 59 3/4" wide and you slip them in there with a shoe horn. The last 2 prints we worked off of were drawn at 5' after drywall.  Thats a typical no-no we all watch out for in the field. Just thought I would throw that out there for those of you who are interested.  SP Rocks

I don't understand what you're saying Daniel.

 

We spec our bathrooms at 61" framed which gives 60" between drywall faces for a 59¾" tub, which you are saying is a no-no ... However, you say that "in the field", that has to be 59" AND you can slide a 59¾" wide tub into that opening ... GOOD LUCK with that ... I assume you mean between framing members, but that REALLY depends on the type of tub you are using. As far as I'm aware a STANDARD tub only unit is designed to fit between DRYWALL faces, so that the flanges on top of the tub sit behind a tiled wall finish.

 

Bottom Line ... When designing or building, don't assume you know the dimensions, GO with the MANUFACTURERS installation specification.

 

If you make the opening too big, you can always frame/shim it out to be smaller ... if you make it too small, then your going to have to demolish and rebuild!

 

We typically use ONE PIECE units ...

Standard 5x9s are drawn at 60 inches on the rough. All 5' standard tubs measure @ 59 3/4. Its important to keep that tub tight against both sides so theres no movement when people use that tub. The drywall is supposed to hang over that flange all the way around.  I think theres others out there that will agree.   We built them that way always..never had one not fit.

In our case, I have to agree with Daniel for a standard bath with ceramic walls. That's more crucial when the room is basically the width of the tub because you don't want to have a small bump out. As with Keith, we install mostly one-piece right now which was a problem with the plans when we switched from standard to to one-piece because of the size differences and lips around the bath.

Having not been in the field, I will have to take your word for it. I'm only saying what I've been told by site staff that I've worked with. Having said that, different area's have different construction methods, and no-one's ever complained they have too much room.

 

All the construction companies I've worked for have INSISTED that bathrooms be DESIGNED at 61" structurally. What is done on site may well be different to that!

 

I will however, stick by what I said earlier ... if you know the what the product is, Go with the manufacturers installation specification.

I just looked at cut sheets from two different tub manufacturers we regularly use and both are 60" units. In 22yrs, I've never come across a 59-3/4" tub/shower. We always rough frame our bath alcoves to 60". Our units are installed to the studs and wall finish covers the flanges.

[Daniel Zanoli]

Its kinda like a 2x4 thing.... the top of the one piece unit which is open in the front without a top..wall to wall actually flex alittle. The bottom is smaller than 5'.  You know what works when its to tight?     The BFH.

I agree with Daniel.  I have several, as I call them, "critical dimensions" on my plans.  One is the rough framing for a standard bathroom is 60" if I am using a standard tub.  Another is the C/L location of the kitchen window, especially if I am using factory cabinets.

For a standard bathroom tub, I use 5'-4" between centers on 2x4 walls.  I just checked, it gives 60-1/2 inch between stud faces.  I have never in 20+ years of designing have someone tell me it was not enough room.  Also, a competent framer should know that a bathroom is a critical dimension.  I only put critical by a dimension if it something out of the ordinary such as a plate height that is not standard that is needed to make the roof come out right.

I go with a 5'7" wide bath as my standard (if all possible). Besides being able to fur a wall in for the tub, I have found that can get a decent batroom door (30") and trim without having to cope around fro the vanity counter top.  

[Daniel Zanoli]

I guess my point was to always mount the tub flush with the surrounding walls no matter what the tub size is. The 5'6 bathroom is a great Idea Tom. Your spot right on about the door and the trim.
