I am just about to start laying out the pipes for my new bathrooms in an extension - anyone got any advice on what I propose?
I have two bathrooms back to back along a dividing 75mm stud wall - this wall (and under it) is where I intend to run all the waste and hot and cold feeds. There are two loos on the wall back to back (with a stagger) the furthest of which is 1.5m from the soil stack location and T connector. I plan to run two lengths of 110mm soil pipe at 1:40 fall within the floor void parralel to the joists (170mm joists) - with the loos connected on a T into the soil pipe.
The upstream end of the soil T I plan to reduce to 50mm to take hand basins (one in each bathroom), still in the floor void.
One of these I plan to reduce further to 40mm to take a shower waste which will be no more than 1.5m from the 110mm soil T, again within the floor void.
The intention is to have two simple runs of soil pipe all contained within the floor void with stubs to attach sanitary ware exiting through the floor boards - space is very tight in the rooms and I don't really have room to box the pipes off along the skirting and need to mount the loos as close to the walls as possible to give max. space in the room.
I am going to deal with the bath waste seperately and plan to T that into the soil stack on its own. The same for one other shower.
Does this sound like a good idea, or am I building myself a headache here?

and is very close to scale drawn - the layout is right within a gnats whisker. Essentially I am looking at doing two straight runs within the floor void to collect all waste and move it on to the soil stack. I plan on fitting access points at the soil stack and in the T's under each loo (to be accessed via the ceiling below in a worst case scenario). So what do you think?
