Frequently Asked Questions
Helpful insights on calculating realistic renovation budgets and timelines.
To get an instant estimate, select the room you plan to renovate (Kitchen, Bathroom, Bedroom, Living Room, Garage, or Laundry), enter your room size in square meters or square feet, and choose your finish grade (Basic, Mid-Range, or Luxury). The guesstimator immediately calculates a realistic estimated cost range and project timeline based on 2026 trade benchmarks.
Renovation duration varies by room type and scope. Simple cosmetic refreshes (such as bedrooms or living spaces) typically take 1 to 4 weeks. Wet areas like bathrooms generally take 3 to 10 weeks, while full kitchen remodels and conversions often take 6 to 16 weeks depending on structural changes, council permits, and trade availability.
A basic or cosmetic renovation focuses on refreshing existing surfaces without altering floor plans, structural walls, or plumbing locations. It typically includes interior painting, cabinet hardware swaps, entry-level laminate benchtops, standard fixture updates, and straightforward flooring installations like hybrid or vinyl planks.
A mid-range renovation balances durability and aesthetics by using engineered stone benchtops, semi-custom joinery, floor-to-ceiling tiling in wet areas, and premium brand appliances while keeping plumbing layouts mostly intact. Luxury renovations feature full architectural redesigns, load-bearing wall removals, custom bespoke joinery, natural stone or imported marble, concealed architectural lighting, and designer European fixtures.
A realistic kitchen renovation budget typically allocates approximately 30% for custom joinery and cabinetry, 20% for appliances and fittings, 35% for licensed trades (carpenters, plumbers, electricians, stone masons, and tilers), and a mandatory 15% contingency reserve. Keeping plumbing waste and supply points in their existing locations is the single most effective way to avoid unexpected budget blowouts. You can also explore our Budget Tracker for detailed cost allocation.
Bathrooms require a high concentration of licensed specialist trades working within a compact footprint, including demolition, plumbing rough-in, electrical, certified waterproofing membrane application, precision tiling, and final fixture fit-off. Strict building compliance and waterproofing standards also make bathrooms one of the highest cost-per-square-meter spaces in any home.
Industry best practice recommends budgeting a minimum 10% to 15% contingency reserve for standard cosmetic or mid-range renovations, and 20% for older homes (pre-1990) or major structural alterations. This buffer protects against concealed issues such as subfloor rot, outdated wiring, obsolete plumbing, or asbestos removal.
Our guesstimator combines room-specific scope requirements with floor area measurements (m² or ft²) and finish quality grades to calculate a realistic cost envelope.
