Drain through joist?

[Mortsken]

What does Bauhaus say?
If they risk having to pay for everything to be torn up again, they should want it to be correct, one might think.
If you have plenty of good pictures and an inspector later condemns it, they will have to tear it up again.

Bauhaus handles it well. They should make sure to go there every day, and all the errors we discover should be sent to him. Unfortunately, he is new and not trained, so he can't argue against the company when they say they have done it right, but the more they are forced to explain and the more I read up on, the easier it will likely become.

This is also via bauhaus. May I ask which city?

Gothenburg, Sisjön but it was higher up in the organization that the decision was made to redo it.

Thanks to all of you who have helped and responded!

I have now reviewed "bygg badrummet rätt," "bjälklagets uppbyggnad" from "säker vatten," "bärförmåga - bjälklag på träguiden," BBV21:1, "säkra våtrum" from GVK, and written down some other points based on the current situation (mistakes they made according to these documents, plus some additional points). Overall, it came to about 1.5 A4 pages in Word. That's just for the current situation with the preliminary work... And it doesn't even include the long list I've already sent them. With that, it’s probably a total of 2.5 A4 pages... To be continued.

New efforts tomorrow! After this, I should be able to switch to an inspector

If you, after having read through the documents you mentioned yourself, find so many errors and observations, I would have stopped the construction until you managed to sort it out with the current builders. Alternatively, I would have brought someone else in. It doesn't sound completely normal to find so much to remark on...

Regarding the drainage for the sink, as far as I know, it should not come up from the floor. As I understood it during the bathroom renovation about 1.5 years ago, all pipe penetrations from the floor except for the toilet and floor drain are not allowed nowadays.

Thanks! That was actually something I missed, but I see that it's stated in safe wet rooms now (I didn't react to wastewater, but that's exactly what it is). I'm unsure if the walls might be too thin to incorporate the drain, which is why they've done it through the floor, but I'll take the question to tomorrow when we meet them again. Nothing happened today. I don't think they will be able to route it through the floor anyway due to the bathroom cabinet's design, so it was already kind of raised as an issue, but now I have more backing.

Yes, that's how we feel too, but now Bauhaus has stepped in to organize, and we won't let the company continue until they've fixed everything. I also wrote and demanded that we get to check each step before they proceed to the next.

Of course, you can have the sink drain through the floor.

In bathrooms or shower rooms, there should be no pipe penetrations in floors with waterproofing, except for drains and floor drains.

Yes, it will be like that. I understood the industry regulations as suggesting that you shouldn't have drainage through the floor if it's not necessary, but that it's most important in wet zone 1. Here, the sink will be at the other end of the bathroom, so I'm not going to fuss about it. If they hadn't already cut out the recess in the "bottom" of the wall, it sounded like they could have routed through the wall, but now it will be through the floor.

Update again: There was a "big meeting" this morning, and now it feels much better. They will install new 45x195 beams on all existing frameworks. All drains and water pipes will be moved and routed through the ceiling in the boiler room below instead, so they don't have to cross the beams. They will be between the beams instead.

I insisted that they need to document deviations, so hopefully, they took that to heart. Went through all the points, and they said they would address everything, and the only thing we didn't argue about was the electrical placement (just aesthetically). So now, hopefully, things will proceed smoothly. Both the foreman of the company and the representative from Bauhaus seem to be more involved now and will go out and double-check all the work every day. We will also try to go there and check how things are progressing before they are covered up by the next step (during the day, that is; in the evenings when we get home, they may have already covered or moved on to the next step).

We/I am probably their most troublesome customer at the moment (and most expensive now that they have to fix everything), but right is right. Fingers crossed for a more seamless continuation.

You are right, I take back what I wrote about it.

There is a lot of "killgissande" in this thread...

There's a lot of mansplaining in this thread...

I've been thinking about writing something based on industry standards, so that if someone reads in the future with a similar problem, they have something concrete to refer to. But I'm thinking I'll wait until everything is sorted out and then write everything together.
