What Impacts the Cost of a Bathroom Renovation?
There are a few major cost factors to consider:
Size of the bathroom: Larger rooms require more labour and materials.
Finishes and tiles: Full tiling, natural stone, and premium fixtures increase cost.
Plumbing changes: Moving your shower or toilet adds cost due to new pipework.
Layout redesigns: Knocking down walls or repositioning elements increases complexity.
Custom cabinetry or mirrors: Going custom adds visual impact, but also adds cost.

Tips for Renovating Without Overspending
Retain the existing plumbing layout to avoid major labour costs
Focus on one or two premium features instead of everything
Use cost-effective cabinetry options with a luxury finish
Limit tile coverage to key areas (like behind the vanity or inside the shower)
