Watch the thickness of the flooring relative to the toilet flange. Using some thicknesses can result in improper sealing of the toilet. An ordinary wax gasket can be used sometimes or an extender may work (you must re & re the foam gasket anyway). Sometimes cabinet doors can be really close to the floor and need to be moved upwards. I had to do this on a previous TT when only using 1/8" think laminate. Bathroom door could be affected too and need trimming off some at the bottom. Don't glue sheet vinyl to the sub-floor. Thick laminate will need a transition strip at the door and may be a nuisance. If using the thin vinyl laminate stuff, I'd only use the interlocking type and it needs to be fully free-floating and will need an expansion gap all around it and a baseboard strip of some sort to cover the gap.
