Kitchen renovation plumbing: what to plan

Sink position, drain falls, appliance water points, filters, hot water and paperwork: the plumbing to settle before you order the cabinets.

A plumber answers 24/7.

Key takeaways

Fix the sink position first. A sink on the same wall is simple; an island sink needs a new drain with enough fall and a plan for venting.
Give us the actual sink, tap and appliance details before rough-in, not after the benchtops have been measured.
Every water and waste connection in a kitchen is licensed work in NSW, whatever it costs, so a licensed Wilco plumber does it, not the demolition crew or a handyman.
Kitchen taps are not covered by the 50°C limit that applies to showers and basins, so the kitchen hot water can run hotter than the bathroom.
At the end you should receive a copy of the Certificate of Compliance and a plan of any drainage work.
