Toilet Installation Costs NZ: Avoid Overpaying (2025 Price Guide)

Why Does Toilet Installation Cost So Much in NZ? (And How You're Probably Overpaying)
That "$150 toilet installation" quote you saw? It rarely ends up being that cheap. Most homeowners actually pay $300-$600 because of:
"Just a small extra..." fees (pipe adjustments +$150, floor repairs +$200)
Specialist toilets (Smart/wall-mounted models add $200+)
Winter tax (June-August prices jump 20%)
Real kicker? Many plumbers don't mention these extras until they're on-site.
"My 'quick toilet install' turned into a $650 disaster when the plumber found rotten flooring and mismatched pipes—none of this was in the original quote!" — Sarah, Wellington
4 Costly Traps Plumbers Don't Always Mention:
"Surprise Removal Fees" ($50–$100)

"After-Hours Tax" (+50–100%)
Got a weekend leak? Emergency fees apply.
Smart Move: Schedule installations Tuesday-Thursday.
"Hidden Repair Bombs" ($100–$500)
Older homes = cracked pipes, rotten subfloors.
Red Flag: If they won't inspect first, walk away.
"Fake Warranties"
Budget installers often skip leak protection.
Must Ask: "Show me the warranty in writing."
