Sink position, dishwasher feeds, gas hob bayonets, filtered water, fridge ice-makers. A short brief on the kitchen plumbing decisions that affect cost and timeline.
Kitchen renovations have fewer plumbing fixtures than a bathroom but more variables. A modern Kapiti kitchen routinely involves a sink, dishwasher, fridge water line, filtered or boiling-water tap, gas hob and sometimes a wall-mounted pot filler. Each of those decisions affects what gets roughed-in before the cabinetry goes in.
Where is the sink moving?
If the sink is staying in the same spot, plumbing is a half-day fit-out. If the sink is moving — to an island, to a different wall, or just shifting along the bench — the drain, hot, and cold supply all need to be re-run, which is a different job entirely. The further from the existing waste stack, the more disruptive the work.
Dishwasher and fridge
A dishwasher needs hot or cold supply (manufacturer-specific), a drain connection, and a power point. A fridge with an ice-maker or chilled-water dispenser needs a small-diameter cold-water line behind the cabinet. These are easy to add at the rough-in stage and a headache to retrofit afterward — flag them up front.
Gas hob — bayonet placement matters
Gas hobs are popular on the Kapiti Coast. The hob connects to a gas bayonet behind the cabinet, which must be installed by a PGDB-licensed gasfitter and supplied with a Gas Safety Certificate. Tony covers plumbing and gasfitting under the one licence, so the hob and tapware can be roughed-in together. Bayonet placement determines whether the appliance sits flush or stands proud — easy to get wrong if it is not specified before the cabinetry goes in.
Filtered, boiling and chilled-water taps
Three-in-one and boiling-water taps (Zip HydroTap, Billi, Quooker) need a small cabinet under the bench for the unit, a power point, a cold-water feed, and a drainage path. They are not difficult to install, but they need to be planned at the design stage — there is rarely room to add one later if the cabinetry is already built.
Coordination beats specification
The single biggest difference between a smooth kitchen renovation and a stressful one is whether the plumber, electrician and cabinetmaker have talked to each other before work starts. Tony deals directly with the builder or designer to align rough-in timing, hob cutout dimensions and tap-hole positions — saving the homeowner from being the message relay.
