What moves the price

Moving the toilet, shower or vanity triggers plumbing and consent questions. Keeping the layout is the single biggest saver.
Waterproofing must be done by the book; it's where cheap jobs fail and insurance claims start.
Tiling area and tile choice swing the price more than most fittings.

Common questions

Do I need a consent for a bathroom renovation?

Like-for-like replacement usually doesn't need one; moving plumbing or altering structure can. Your plumber or builder should tell you before work starts. Get it in writing.

How long does a full renovation take?

Commonly two to four weeks on site once materials are confirmed. Longer if consents or custom joinery are involved.
