Is this a reasonable price for pipe replacement?

The most obvious is the material cost.

Agree. Approaching the final phase of the same project and in this context, the material cost is a drop in the ocean. Spent about 5' on pipes and about 5' for a pallet of concrete. The work time is harder to say anything about. In my case, it has taken a considerable amount of time due to rocky ground. But I think it's not a 725 SEK/hour job. A large part of the work is completely unskilled excavation work that you can put just about any gnome on.

As mentioned, also the work. We made such an effort a couple of years ago. In our case, there were about 10 m of pipes under the floors, but they needed to bend about 3 times, with a total of 6 branches to the shower room, basement toilet, washing machine, etc. It cost a total of about 75,000. Then I bought some of the pipes myself, another 3,500. And I hired diggers and hole cutters. We went out through the foundation wall higher than the old pipe to avoid breaking up so much of a marble floor. The old pipes were almost 1m under the basement floor. I also hired the hole cutting company myself. It was about 80 cm of granite foundation that needed to be holed through. Digging and hole cutting cost about 15 - 16,000, before ROT. I have restored the tiled floors myself, about 15 sqm of tiles, and had to retile the walls in the basement toilet. The marble floor still needs to be fixed. There will be a cabinet where it was cut up.

Worked extra on a museum ship and instead of releasing fecal matter into the lake, we had to install a septic tank. It was hardly feasible to install thick sewage pipes that would have to go through centimeter-thick steel plates. So we chose the option of using regular steel pipes of about 20 mm. To prevent blockages in the pipes, we placed a sewage grinder under the toilets that ground up the sewage water, which worked well. I'm considering if there's a similar system that could be installed in a house while new sewage pipes are being run. I don't have major problems with the sewage pipes in my house and am wondering if there are any DIY alternatives for me, with a house from 1966, perhaps a pressure washer and self-applying a layer of plastic inside the pipes. There is a company that often approaches homeowners offering relining for well over 100-200,000:- which seems like a waste of money to me.

Hardly feasible to install thick sewer pipes that need to be run through centimeter-thick steel plates. So we chose the option of using regular steel pipes of about 20 mm. To avoid blockages in the pipes, we placed a grinder under the toilets that ground down the wastewater, which worked well. Considering if there is a similar system one could install in a villa while installing new sewer pipes. I don't have major problems with the sewer pipes in my house and am wondering if there are any DIY options for me, with a house from 1966, perhaps a power washer and maybe spraying a layer of plastic inside the pipes myself. There's a company that often approaches homeowners offering relining for well over 100-200,000 SEK, which I think seems like a waste of money.

Yes, I believe there are such toilets. How well they work, I don't know. We had toilets that looked and sounded like the ones on an airplane at a workplace, and there were often problems with them... I suspect they were exactly those with a grinder...
