Basement bathroom

Hello all. Im currently trying to build a bathroom in my basement but was wondering if the following design is correct(dont mind the 2 vertical pvcs with caps, they're just temporary). I would like to have a toilet on the left and sink and shower on the right. For the sink i will just use the laundry sink pipes and convert it to a regular sink. But for the toilet and the shower im not sure if its correct?

Thanks.
