As per the subject, it would be much simpler for me to run 2 x basins (main bathroom, and next door en-suite) joining via a swept tee into 1 40mm waste boss into the stack. Pipes will be 40mm throughout (unless that is unnecessary).
Is that compliant? I know I'm best running separate wastes, but if I can use 1 boss on the stack, it will hugely simplify the boxing in task. However, I do want the install to be compliant with BRs so will do what is correct in any case. Appreciate any help - about to order the porcelain, and 2 sharing 1 will equal 2 pedestals (preferred), and 2 separate will require me to use an inset vanity basin and build a vanity unit (not preferred!).
Thanks.
