Drain through joist?

[Pflugmacher]

Here is a picture of the current state in the bathroom. There you can also see how they framed around the drain in the shower.

Another question. I wonder if it's okay that they have cut out for the water pipes the way they have in the horizontal beam that runs along the floor, which the wall beams stand on?

The beam at the water pipe to the toilet also looks a bit questionable (but it probably looked like that even before they started working).

they need to reinforce better around the floor drain and they must reinforce the holes in the floor joists where they have made holes. Then you don't run pipes from the floor to the sink. It's amateurs who do that. It should look neat. What they have cut out for water pipes in the wall is okay. As long as they have put extra screws in the remaining ones. Regards, carpenter.

Do you mean the drainage pipe? No, I haven't seen it go through the floor that often in new bathrooms either, but I guess it's still okay to do so? It looked like that in the newly built rental apartments I've lived in as well.

Now you have already received a lot of good answers about the drilling and that it needs to be redone, we had the same problem when our bathroom was renovated in 2018, large cutouts in the joists. 2 years after it was finished, I noticed that a tile cracked when we walked on it. After much back and forth, it turned out that the waterproofing had come loose from the leveling compound. Probably due to the sag in the joists as it had been weakened so much by the cutouts. The entire bathroom was torn out and redone earlier this year with strong reinforcements in the joists. Then with 15mm plywood that was screwed and glued just as the answer above says.

So stand your ground, bring in an inspector who can do a 3-stage inspection of the bathroom (construction, waterproofing, and final inspection) so you can be sure it's built according to all regulations afterwards.

That might be why a couple of the old tiles were cracked at our place It was cut out just like for TS during the last renovation in the 70s. Now it's reinforced, in the same way with plywood on both sides.

But how unfortunate for you! Did you have to pay for the second renovation?

I saw that I missed writing about the drain pipe. It should go out through the wall. Behind the cabinet that the sink is on. Pipes are never allowed to go up through the floor anymore. Not among those I work with.

No, we did the bathroom through Badrumsvärlden at Bauhaus, so they covered everything since they offer a guarantee. The new company they brought in found several other fairly serious errors when they tore it down, so in the end, it was a relief to redo it.

This is also through Bauhaus. May I ask which city?

Thank you ☺️ Yes, I'd rather "argue" now than be dissatisfied with the result. And yes, it's such small amounts in the grand scheme of things, so it might be worth it. We also need to mention the insulation in the walls. They removed it but didn't put it back (now that the walls are taken down again). If we need to pay extra for that, it would be worth it too. It's so unfortunate if the whole house echoes from the bathroom.

the strength of a beam is directly related to the height of the web. The beam (the rule) has virtually no strength left, at least significantly weakened. Reinforcement is obviously necessary, and then the flooring will stabilize the construction. So with simple means, a professional can solve this. I am an amateur carpenter and would not do it like that.

Thanks! I will continue arguing with them on Monday, and it feels much better that several of you agree that they should be reinforced. I'll sit down tomorrow and summarize all the points, and we'll make sure they don't cover the walls and floor until we've been able to check that they've fixed everything.

Stand your ground.

Ask them to document the removals and explain why it is okay in writing.

Yes, the studs aren't there because the house builders had some left over; they look pretty sturdy for a reason.
I am NOT impressed by "Professionals" "Doctoring" when I have to do something.
I'm in the process of replacing an engine in a 2015XC70 which, against my principles, I left with Volvo for a timing belt change...
70,000 km later the engine failed because the mechanic did NOT reinstall the nut on the crankshaft pulley...
Costs me about 40,000kr and a hell of a lot of hours.

The studs aren't there because the people who built the house had some left over, they look pretty solid and even that has a reason.

7000 miles later, the engine gave out because the mechanic DID NOT reinstall the nut for the pulley on the crankshaft...
It's costing me about 40,000kr and a hell of a lot of hours.

No but of course...

Oh my god... But didn't they cover that cost if it was their mistake? No, car mechanics and craftsmen rank low on my list of professions I trust.

They said it couldn't have happened any other way, but it's difficult to assert your rights after such a long time...
Therefore, it's important for you to be involved and document now, showing that you've opposed in writing. Otherwise, it's just word against word, etc.
Damn, not fun, but you are paying, and it should be done professionally!

I get a lot of rabbatt on Volvo because of this.

 

[Lity]

I get a lot of discount on Volvo because of this.

That's good at least. And thanks, will make sure to document even more, and get their assessment in writing.
