Cutting the whole joist and doing it right?


Hi, I am doing a washroom and ran into a problem.The shower pan drain is right in the spot of the joist and needs to be cut right through.I came up with a plan and need some advice if I am doing it right or not Thanks Mike

Here are a drawing I came up with and a real picture:

I'll wait for an engineer to answer that for you.

Have you considered building a custom pan? That would save you a lot of work---

You have it exactly right.
Usually you would double-up any joists that have a head-out hanging from them, but that's next to impossible given your situation.
Hopefully the pan doesn't weigh a ton.

Exactly my thought---joist holding the crippled ones needs to be doubled--Lots of work--

Parts for a custom pan are only about $150--

Cutting the whole joist and doing it right?


Believe me if it was up to me I would have use schuler and tile it already,but prego wife said no tile and that was that

I have a few more questions:

The 4 feet joist from the wall runs another 14 feet for a total of 18 feet to the out side wall.Will this affect anything?

I am not sure there is any support underneath the 18 feet.But there is a wall underneath it that separate the dinning room and the garage.I am not sure if this wall holds up the 18 feet joist?

If the wall does not hold it up would there be a problem when I cut it?

Oh and half of the bath tub sit at the end.Between the 8 feet joist and the support joist,right beside the wall.Will the weight be any concern?

Thanks a lot for all the help!

Mike

Is the drain dead center or off to the side a little? There is offset drain the can get you over some if you can use it. You may need to notch the top of the joist and sister another one beside it.

Or like this for a toilet, have also seen for a shower

I would screws 2, 2 X 6's laying flat over the floor joist from above for support while cutting, to stop them from sagging and moving around causing screw pops in the sheetrock below.
I'd be looking hard at the idea of building that back wall out some so the drain would clear instead of all that other work that may or may not work.
Are those water lines in an outside wall? Big no no around here, even if there on the warmer side of the wall. Looks like the left ends are uninsulated and turn to the outside?
It also looks like you did not have a Toe Kick saw to cut off flush with the wall, what's the plan to support the back of the sub flooring.

Good catch on the water lines. If they absolutely (and I mean absolutely) Have to be in the wall put your poly between the lines and the insulation.

Looking closer at the picture and your sketch I think I'm saying that those are actually engineered joists instead of 2x#s. If they are then you can't use brackets like you're showing to attach to them and sistering is also in major problem. If those are engineered joists that you definitely need to consult with a structural engineer.

To sister them fill in with plywood and nail them together.
As this is structural you probably should have a permit in most areas. Where I used to be there was no permits.

After much thought I decide not to cut the joist,instead I decide to move the pan out 4'' and put a piece of granite or marble to make the pan bigger.

Those two are waterline yet to be connect to a shower trim and it is on a out side wall.I will insulate some more after wards.

There will not be a sub floor,because the shower base is made to sit on the joists so it will be level to the tile floor.

Yes those are engineer joists,I screw on some 2x4 on the side of the osb boards and put another 2x4 across the top of the one's I screw on to give the shower pan some support is this how you do it or is there another way? Thanks

Not quite understanding. You are adding a 4" strip to the pan? How will this be sealed? Could you add a 2x4 wall behind the shower and then this gives a place for your water lines, kinda a wall inside a wall, vapor barrier would go between the two walls.

Also is that light right below your shower area? This is considered a bad idea in case you have any leaks.

I will be using kerdi band and kerdi fix and ditra to water proof floor and wonder board for the walls.doing a 4'' wall is not a option,because I would have to do the whole wall and I would have to move the tub and toilet.If I just do the shower it won't look good.

Am I doing it right by just screwing the 2x4 on to side of the engineer plywood joist or is there another way of doing it to give support to my shower pan?Thanks

Just a thought---many granite counter top outfits will make custom shower pans from synthetic materials

Just a thought--not every one likes a tiled shower base --there are other materials---Mike---
