Factors That Affect Shower Waterproofing Cost
Shower Type & Size
Walk-in showers cost more than standard recesses due to larger area and additional waterproofing around frameless glass channels.
Drain Type
Linear (strip) drains require more detailed waterproofing than centre-point drains, adding $100–$300 to the job.
Hob or Hobless Design
Hobless (step-free) showers require more precise falls and membrane work, which can add $200–$500 compared to a traditional hob design.
Wall Height
AS 3740 requires waterproofing to 1800mm on shower walls. Full-height waterproofing (floor to ceiling) costs more but offers better protection.
Niche & Shelving
Built-in shower niches require additional waterproofing detailing, typically adding $80–$150 per niche.
Existing Condition
Re-waterproofing an existing shower with tile removal adds significantly to cost versus waterproofing a new build.
