Bathroom Renovation in Hamilton

Keep the existing layout, choose mid-range fittings from stocked lines rather than special orders, use large-format tiles only on feature areas, and paint rather than tile ceilings and upper walls. Do not economize on waterproofing, drainage falls, or the tiler's labour — those are the items whose failure costs multiples later.

If the renovation strips the shower area back to the substrate, waterproofing must be redone — a failed membrane is the most expensive bathroom defect there is, because the fix means demolishing finished tiling. Several countries regulate wet-area waterproofing explicitly. Never let a contractor tile directly over an old or damaged membrane.

A straight swap-in-place refit takes about 1-2 weeks; a full renovation with new waterproofing, retiling, and any layout change takes 2-4 weeks. Add waiting time before the start for fixture delivery and trades scheduling — and note that waterproofing membranes need curing days you cannot compress.

Run every fixture: check drainage speed, look under the vanity for weeps, confirm the shower floor falls to the drain (pour a bucket and watch), check grout lines are even and silicone is continuous, and test the extractor fan. Photograph everything and get the waterproofing product and warranty terms in writing before releasing final payment.

Around 10-20% is normal, sometimes more where custom vanities or imported fittings must be ordered up front — in that case pay the supplier invoice share, not a round 50%. Hold 5-10% back until the room has been used for a week or two and the snag list (grout gaps, silicone, door alignment) is closed.

Standard full renovations typically run NZD 18,000-35,000, with budget refreshes from around NZD 10,000 and high-end projects NZD 50,000-75,000. Costs track Australian levels because trades licensing and materials import costs are similar.

Replacing fixtures in the same positions is generally exempt work; moving the toilet or shower, altering drainage, or creating a new bathroom needs a consent from your council. Your plumber or renovator should tell you which side of the line your plan falls on — get it in writing.
