Renovating a bathroom in Sydney can range from simple upgrades to complete overhauls. But understanding what drives costs — especially in apartments across the Eastern Suburbs, Inner West, and North Shore — can help you budget smart and avoid nasty surprises.
At Milani Concepts, we specialise in bathroom renovations designed with both function and architectural intent. Here’s what you need to know.
🌟 Factor 1: Scope of Work (Cosmetic vs. Full Renovation)
One of the biggest cost drivers is whether you’re doing surface-level upgrades (e.g., fixtures, paint) or a full gut renovation.
Cosmetic refreshes:
Tapware replacement
Regrouting
Vanity upgrade
Full-scale renovation:
Waterproofing
Layout changes
New plumbing/electrical
✅ Tip: A full renovation offers longer-lasting results and better resale value, especially when designed smart from the start.
💧 Factor 2: Waterproofing & Compliance
Waterproofing is a non-negotiable in Sydney apartments. Poorly done waterproofing is one of the leading causes of hidden damage.
Key issues:
Leaks into units below
Failed membranes
Strata disputes
✅ Tip: Ensure your builder is licensed and compliant with AS 3740. At Milani Concepts, we document every layer of waterproofing with photo records — protecting you legally and structurally.
🛏️ Factor 3: Material Selections
Materials have a huge impact on cost — and durability.
Examples:
Ceramic tiles vs. natural stone
Wall-hung vanity vs. freestanding
Frameless shower vs. semi-framed
✅ Tip: We guide you to make timeless, low-maintenance choices that also maximise space in tight bathrooms.
🌀 Factor 4: Access & Apartment Location
High-rise buildings = more logistics. Lifts, loading zones, noise curfews — all affect cost and timeline.
Common added costs:
Waste removal
Material handling
Council permits (for skip bins etc.)
✅ Tip: We handle all logistics upfront so there are no shocks mid-project. We also deal directly with strata for approvals.
