Hi,

I'm renovating my basement. The drainpipe had broken in the concrete foundation. Really lovely. I've removed all the material down to the concrete, built a new room that will be a bathroom, and the rest of the space will be used as a home theater room (I call the area "gillestuga" in the attached picture).

My wife is pregnant and due in 1 month, I have cell changes in my throat, can't hear in my right ear, I'm changing organizations at work, and I'm winter-tired. And now I want to get this done before the baby arrives so I can breathe a bit :)
To avoid overexerting myself, I've decided to wait on much of the work, just focus on the home theater room, skip the bathroom (which is good in itself) and the room next to it (which is not included in the drawing). I've already built new walls in the home theater room, and now it's time for the floor. Leveling floor, on top of that floor chipboard, then grooved EPS foam boards where I'll place floor heating pipes, on top of that more chipboard and a mat.
This is what I intended to do first and wait with the bathroom until I have new energy.
But I'm not quite sure how to do it. I want to run all the water pipes from the same distributor. 3 of them will be used for the home theater room, 1 for the bathroom. What should I do? Should I run to/from under the floor to the bathroom and roll up the rest of the pipe in the bathroom to use it later? Is it really possible to lay out a rolled pipe on a reinforcement mesh? Doesn't it require having one end free so you can "spin" the pipe? With each loop in the roll, the pipe is a bit twisted.

The alternative is to finish the bathroom floor concerning floor heating. I want the floor to be at the same level as the rest of the room, i.e., 17cm.
My first thought was to pour in concrete, put on reinforcement mesh to attach the pipe to, then add more concrete. But this is technically difficult. The room isn't very large, and it will be hard to move around the room with rebar and wet concrete. It feels like there must be simpler ways!

I hope someone can help me! I'm going to start framing the floor in the home theater room this weekend, and I don't want to mess up, this could get expensive :)

Best regards,

Stefan

One way to simplify the piping in the toilet is to use the thinnest pipes.
 
The experience I have with underfloor heating pipes is that they are quite stubborn to work with. Whenever we've laid them, we've always kept both ends free, whether I've used glued mounts on the concrete slab or attached them to the reinforcement mesh. In your case, I would have run both the supply and return to the toilet room and cut them there.
When it's time to fix the toilet, you just put on a joint and connect it after the pipe is laid out.

I have always used self-leveling compound, more expensive than concrete but no problem walking around a bit in it and leveling it with the scraper. Moreover, you can lay tiles directly on the leveling compound and don't have to wait for months like with concrete.
 
Excuse a cautious OT question, but you yourself are signaling that it's a bit heavy right now and it seems like the urgent plumbing problem is fixed. Is it very important that the bio room gets finished right now?
I don't know, you might be on your fifth child and do such things with a yawn between breakfast and lunch, but for many (most?) a rested adult in full senses is usually more needed the first time with a newborn than a bio room. And that person will probably not be your wife.
"Breathing out" is not really what I associate with that period...

Thanks for the tip,

so is it allowed to do that? Make a joint in the floor?

I don't know, maybe you're on your fifth kid and do stuff like that with a yawn between breakfast and lunch, but for many (most?) having a well-rested adult in full command of their senses tends to be more necessary the first time with a newborn than a home theater room. And that person probably won't be your wife.
"Exhale" is just not what I associate with that period...
Yes, you're absolutely right.
The idea is to get all the rough work done as soon as possible, so I don't have concrete dust, sawdust, and debris all over the house when the little one arrives (and it's our first child).
Then I also work in a way that I need to work physically during stressful periods, now when I work, I stop thinking about my throat, which I think about all the time otherwise.
This is not quite the pregnancy either my wife or I had imagined.
 
I have a joint in our kitchen floor because I managed to drill a hole in the pipe when I was installing the kitchen fittings. So I took up the tile and chipped a hole in the concrete around the damage, cut off the pipe, and installed a joint, then I re-leveled the floor and put the tile back.
That was the plumber's solution, so I assume it's okay and permitted, it's held since 2003 anyway.

But otherwise, you could pull the pipe up on the wall and connect it there and then down into the floor again; in a bathroom, you can always place a laundry basket or a small cabinet or something in front.

It was the plumber's solution, so I assume it's okay and allowed, it has held since 2003 at least.

True! That's what I'll do!

It is the case that in the heating system you can splice in the floor or wall since it is a closed system and the damage will be limited if it gets a hole. On potable water, you are not allowed to splice in walls or floors.

I understand, tough situation...
That you must not forget to talk to each other about it so your wife gets it too, you probably already know.
Keeping my fingers crossed that everything works out for the best, good luck!
 
Hi,

A little update.

The craftsman did as you suggested and plugged the hose in the bathroom. Since it is a closed heating system, it is okay to make joints in the floor.

Regarding the rest.
I have cancer in the throat. I've let go of the basement now, mostly because I can't manage anymore. Unfortunately, I'm getting weaker quickly.
Surgery in 1½ weeks, then we'll see how it goes.
Childbirth in 1½ weeks. I might not be able to be present at my firstborn's delivery.

Life is tough sometimes...

Words are not enough; sometimes life burdens some people more than anyone should have to bear. My thoughts are with you, and I hope it goes well...
 
No, suddenly underfloor heating is not so interesting. Can only wish you good luck and hope that the operation goes well for you and for mother and child with the birth!
