Currently rennovating my bathroom and intend to do the following?

1.Place Hardboard over the floorboards to cover the whole bathroom
area
2.Then place Lino to cover all area
3.Then place all bathroom stuff i.e bath, pan & Cystern etc over lino.

A few people have suggested against 3. they have recommended that I
lay all my bath stuff first and then place lino.

Just wanted some recommendations from guys here as what would be the
best way?
