Bathroom Renovation Scope Checklist

📐

Confirm layout — keep or change?

Keeping the existing layout saves $3,000-$8,000 because plumbing stays in place. Moving the toilet, shower, or vanity requires new waste and water lines.

🔲

Select tile type and size

Floor tiles, wall tiles, feature tiles. Larger tiles (600x600) look modern but need flatter surfaces. Mosaic tiles cost more in labour. Choose before quoting.

🚿

Choose shower type

Over-bath shower, walk-in, or wet room? Frameless glass screen ($800-$3,000) or semi-frameless ($400-$1,200)? Recessed niche or corner shelf?

🪞

Select vanity style

Wall-hung (modern, easy to clean under) or floor-standing (more storage)? Single or double basin? Stone top or integrated?

🚽

Choose toilet

Back-to-wall (modern), close-coupled (standard), or wall-hung (premium, needs structural support)? Soft-close seat?

🔧

Select tapware finish

Chrome (cheapest), matte black (popular), brushed nickel, or brushed gold (premium). Mix and match looks disjointed — pick one finish.

💡

Plan lighting

Overhead downlights, vanity sconces, backlit mirror? Bathroom lighting must be IP-rated for wet areas. Plan this before the electrician roughs in.

🌬️

Plan ventilation

An exhaust fan is essential to prevent mould. Ducted to outside (not into the ceiling cavity). Timer or humidity sensor?

♿

Consider accessibility

Grab rails, curbless shower, lever taps, and wider doorways add minimal cost now but major value for ageing in place or resale.

📄

Confirm waterproofing scope

AS 3740 requires waterproofing in all wet areas. Full room or just the shower? The waterproofer must provide a certificate of compliance.
