Good idea, I will put the hose down it. Should I crank it up full blast, or is that too extreme?

Thanks for this, I will look at getting one of these corner pieces. For the shower I will use the channel in the concrete and pipe it to the white waste pipe next to the water supply.

I am renovating a cottage in a remote location in Scotland, so trying to learn and do a lot of things myself. One problem I am trying to figure out is how to get a new bathroom installed into a cottage that has concrete floors and 600mm thick granite stone walls. The cottage originally had a small ensuite bathroom on the ground floor and a big bathroom upstairs, which had two separate waste pipes that are in the concrete. This then runs to a run off outside the cottage to a concrete box thing with a concrete slab over it (what is the technical term for this), which then runs downhill to a septic tank. Here is a rough diagram (no to scale) showing all pipes. Here is a picture of the water supply and waste pipe. This originally used to be a coal / utility room in the cottage with a small sink. Here is a picture of where the two soil drain pipes (collars removed), note the drain pipe with a pot covering it to mark its position. The drain pipe (closest in the photo), which originally served upstairs is now sealed over. The other soil pipe is marked/covered with a pot in the background of the photo. Note that there was channels on the concrete floor which originally had wood packed in them for the partitions. They were also concreted over. Here is a pic showing perspective of the whole cottage inside This is a rough floor layout of what I want to achieve, with a bathroom over on the left side of the ground floor. How can I get this waste from the left side of the cottage to the right side's waste pipe? I had a look at 110mm waste pipe connections and there doesn't seem to be a connection that is at 90 degree angle, is there a technical reason for this? This is a diagram of what I was after What other options are there, someone has suggested a machine that you can fit to a toilet that basically acts like a blender / pump for these tricky situations, that lets you use the smaller (white) waste pipe. I am just a young lad with some practical knowlege and a bit of common sense. If I could fly the A-team of builders up to do it all for me I would... Any suggestions?
