About to assist sister-in-law refit her bathroom.

They have purchased laminate flooring (suitable for bathrooms).

Would people suggest :

a. remove old toilet & pedastal sink, fit laminate flooring, fit new
toilet & sink over new laminate floor

or

b. remove old toilet & pedastal sink, fit new toilet & sink, fit new
laminate floor by cutting round sink & toilet ?

or

c. some other (better) method ?

Cheers
