Plumbing & bathrooms·Planning worksheet
Replace a tap or mixer: costs and options
Budget for a new kitchen or bathroom tap plus installation.
BEFORE YOU BEGIN
What shapes the cost?
Tap design, isolation valves, flexible hoses and access.
Compare identical scopes before choosing a contractor. Ask which preparatory work, materials, disposal, GST and site access requirements the quote includes.
YOUR PROJECT ESTIMATE

BETTER QUESTIONS
Ask before you accept a quote.
- Is the tap supplied? Will old seals and hoses be replaced?
- Is GST included, and is the price fixed or estimated?
- Are removal, disposal, access and making-good included?
- What changes would trigger extra costs, and who approves them?
- What is the warranty on products and workmanship?
Safety and licensing
Plumbing and drainage work may require a licensed plumber. Check the rules for your state or territory and whether permits are needed.
THE NEXT STEP
Compare the same job, not just the price.
Record itemised inclusions from at least two quotes, then evaluate differences in quality, warranty, timing and exclusions.
