Bathroom renovation skip bin planner

The direct answer

A 3m³ skip bin handles a standard bathroom strip-out; take a 4m³ if you are also removing the floor screed, a built-in bath or wall tiles from a second room.

A single bathroom is a small-volume job with dense material. The rubble looks like nothing on the floor and fills a bin faster than people expect, because tiles, screed and a cast bath do not stack — but the volume of one bathroom rarely exceeds 3m³.

Why the internet gives you five different answers

Search this question and page-one Australian results will tell you 2m³, 3m³, 4m³, 6m³ and 8m³ — a fourfold spread for the same job. One operator's guide recommends 3m³ for "a small kitchen or bathroom" and 8m³ for a "simple bathroom renovation" on the same page.

None of those recommendations cites anything. Ours is operational judgement from arranging these bins, and we would rather say that plainly than present a guess as a finding. What we can measure is that 3m³ and 4m³ are the two most-booked sizes on this business overall — together 49.5% of 313 sized orders in the 65 days to 30 August 2026.

What goes in

• Wall and floor tiles, and small amounts of screed and mortar
• Vanity, cabinetry, mirrors and shelving
• Bath, shower base, shower screen and toilet pan
• Plasterboard, villaboard and cement sheet that has been cleared as non-asbestos
• Timber framing, skirting and door
• Packaging and general strip-out waste

What size, and what it costs

Live prices from our booking engine, general waste, 7-day hire, including delivery, collection, tipping and GST. Source: demand-ladders.json — 305 Australian postcodes captured 30 August 2026 for a 7 September 2026 delivery, live supplier-network quotes only. n is how many of those 305 postcodes were priced at that size.

This is not the same measurement as our skip bin price index. That page reports our published price list — a mean of the lowest advertised catalogue price for each size across 826 metropolitan postcodes — where the national 4m³ reads $534 (source dataset catalogue-stats.json, generated 27 August 2026; index read 31 August 2026). Those are list averages, not quotes. The figures above are medians of live supplier-network quotes across 305 postcodes, metro and regional, captured 30 August 2026, where the 4m³ median is $446 over n = 275. Mean against median, published list price against live quote, 826 metro postcodes against 305 mixed: the gap is method and population, not a price change, and neither figure supersedes the other. The index says as much itself: "A live quote for your own postcode is often lower." If you quote one, say which one.

Enter your postcode for the live figure where you are.

Stepping 3m³ up to 4m³ costs a median $97 (n = 232 postcodes priced at both sizes). Hiring a second 2m³ because the first bin filled costs a median $155 more than having taken one 4m³ (n = 221) — and is the dearer option in 97% of those postcodes. If you are genuinely between the two, the 4m³ is the cheaper mistake.

Which waste category — this matters more than the size here

Book a bathroom as general waste if the load is mixed strip-out material with tiles as a component.

If you are taking up a tiled concrete floor and the bin is going to be mostly rubble and screed, that is mixed heavy waste or mixed rubble, and it costs more for the same 4m³: across 33 postcodes, mixed heavy waste ran a median $106 above general waste at 4m³ and was never once cheaper in the 32 postcodes where both priced. Mixed rubble ran a median $76 above.

Booking general and filling it with rubble is the failure mode. On our own orders, 12 of 338 paid orders (3.6%) carried an "upgraded to…" correction after booking, and 11 of those 12 were upgrades into a heavy or mixed-heavy category — the most common post-booking correction on this business is the wrong category, not the wrong size.

What is NOT allowed

Asbestos is the specific risk in this job. Bathrooms in homes built or renovated before the late 1980s commonly used asbestos cement sheeting behind tiles and under vinyl flooring. It must be assessed, and removed by a licensed asbestos remover. It is never accepted in a skip bin, in any quantity.

Also never accepted in any bin, no exceptions:

• Chemicals, liquids, oils, fuels, paints and solvents — including part-used tile adhesive, sealant and grout additive
• Gas bottles and aerosols
• Batteries
• Clinical or medical waste

If prohibited items are found after collection, contamination and disposal fees are charged and the load may be rejected.

Practical notes

• Take the 7 days. For the same 4m³ bin, 3, 5 and 7 days were the same price in 60% of the 60 postcodes tested on 30 August 2026. A bathroom rarely comes out in a weekend.
• You load it. We arrange the bin, deliver it and collect it. We do not do manual removal, loading or carrying — worth planning for if the bathroom is upstairs.
• Check the permit. If the bin cannot sit on your own property it goes on the street, and that needs council approval in most areas.

Where the waste-category figures on this page come from

Source: waste-categories-live-probe-20260830.json — nine categories priced at 4m³ across 33 Australian postcodes on 30 August 2026 for a 7 September delivery.

That file records prices only; it carries no per-quote source flag. Cross-matched against waste-type-prices.json (1,485 quotes captured the same day, every one flagged LIVE_NETWORK), 149 of its 264 values are independently confirmed as live supplier prices, agreeing to the dollar with zero disagreements. The other 115 — 16 postcodes, including all 8 Western Australian, the 1 South Australian and 7 of the 8 Queensland postcodes — cannot be certified either way, and are not presented here as live supplier prices. Every direction reported above survives a cut to the confirmed-live values only; the magnitudes on mixed rubble and light building waste do not, and should be read as approximate. The full split and the sensitivity table are on what waste category do I need.
