Bathroom renovation work we do in Toowoomba
A bathroom is the highest-trade-density room in your house. In a 4 square metre space you've got waterproofing, plumbing, electrical, tiling, plasterboard, carpentry, glass and cabinetry all interacting. When one trade does something the next trade has to fix, the job blows out by a week and the homeowner pays for it.
KGW runs bathroom renos with one person responsible for the join between trades. Kevin handles all the plaster and carpentry himself (the two trades on site every week), and coordinates the waterproofer, plumber, electrician and tiler around that. Same standard from demo to fit-off.
Three reno types we take on. Refresh: keep the layout, replace tiles, fixtures and vanity. Done in 2 to 3 weeks. Full demo and rebuild: strip to the studs, new wet-area board, new everything, optional layout changes. 3 to 5 weeks. Premium: custom vanity, premium tiles, layout changes, frameless screen, niche details, in-floor heating. 5 to 7 weeks.
For other room types see renovations Toowoomba (the hub page covers laundries, kitchens, full-house and additions).
Why a dual-trade builder runs your bathroom
Most bathroom renos in Toowoomba are managed by a tiler, a plumber, or a general builder who subcontracts most of the work. The first two are great at their trade but get squeezed when the plaster or carpentry side runs late. The third makes money on the markup between trades.
The honest pitch for KGW: Kevin is a qualified carpenter and qualified plasterer with 14+ years on the tools. In a bathroom reno, plaster and carpentry are the trades on site every week from demo through to final fit-off. Doing them himself means no subcontractor markup on the biggest-time trades, no scheduling games between his own plaster crew and his own carpenter, and no finger-pointing if a sheeting line doesn't meet the tile edge cleanly.
The trades that are not on site every day (waterproofer, plumber, sparky, tiler) are coordinated by Kevin. They're local Toowoomba operators he's worked with for years. You get one quote with everything included, one MBA Minor Works Contract, one main contact, and one workmanship warranty on the building work.
How much do bathroom renovations cost in Toowoomba
Three honest tiers based on real Toowoomba pricing. Every job is quoted in writing as a fixed price after the design and selections are locked in. Site visits are $199 for bathroom renos (more detailed than other quote types), credited toward the total if you proceed.
Biggest price drivers are tile area (a fully tiled bathroom uses 18 to 25 m² of tile), vanity quality, screen choice (semi-frameless vs frameless), and whether plumbing relocates. Sticking with the existing layout saves $3,000 to $6,000.

- 5. Contract and deposit. Master Builders Queensland Minor Works Contract for residential bathroom renos. Deposits stay within QBCC limits (max 10% on residential). Stage payments aligned to milestones.
- 6. Demolition and rough-in. Existing bathroom stripped to the studs. Plumbing and electrical rough-in done by the licensed trades. Framing changes if needed. New wet-area board installed and set. Roughly week 1 to 2.
- 7. Waterproofing, tile and fit-off. Licensed waterproofer applies the membrane to AS 3740 standard. Tiler lays floor and walls. Vanity, toilet, basin, screen and finishing carpentry installed. Roughly week 2 to 4 (or 5 to 6 on premium jobs).

Bathroom renovation questions
How much does a bathroom renovation cost in Toowoomba?
Three tiers. A refresh (retile, new fixtures, same layout) runs $8,000 to $15,000. A mid-range bathroom (full demo, possible layout changes, mid-range fixtures and tiles) runs $18,000 to $28,000. A high-end bathroom (premium fixtures, custom vanity, layout changes, premium tiles, frameless screen) runs $32,000 to $50,000 plus. The biggest cost drivers are tile area, whether plumbing relocates, vanity quality, and the screen/shower setup.
What's included in a bathroom renovation?
Demolition, framing changes, wet-area plasterboard, ceiling work, waterproofing (coordinated with a licensed waterproofer), plumbing rough-in coordination, electrical coordination, tile prep, tiling coordination, fit-off of vanity, toilet, basin and mirror, cornice and finish carpentry, skirting and trim replacement, door and door frame replacement if needed, plus full cleanup and walkthrough at the end. The licensed waterproofer, plumber, electrician and tiler are coordinated by Kevin so you deal with one main contact.
How long does a bathroom reno take?
Most bathroom renovations run 3 to 5 weeks on site. Demo and strip-out is 2 to 4 days. Plumbing and electrical rough-in plus framing is around a week. Waterproofing and tile prep is another 3 to 5 days. Tiling itself is usually a week. Fit-off, cornice, finishing carpentry and walkthrough is the final 3 to 5 days. Premium bathrooms with custom vanities or imported tile can run 5 to 7 weeks.
Why hire a dual-trade builder?
Bathrooms are mostly plaster and carpentry once you strip back the fixtures. The waterproofer, plumber, electrician and tiler are in and out for a few days each. The plaster and carpentry trade is on site every week from demo to fit-off. A dual-trade builder like Kevin handles the highest-volume trades himself and coordinates the rest. One quote, one contract, one point of contact. QBCC 15552933 covers the building work.
Do I need a licensed builder for a bathroom reno?
Yes. In Queensland, any bathroom renovation over $3,300 must be done by a QBCC-licensed contractor. Most bathroom renovations cross that threshold the moment you add labour and materials. KGW holds QBCC licence 15552933 (SC1 class, $200,000 trade contract limit) and uses a Master Builders Minor Works Contract for residential renovations.
Can I keep using the bathroom during the reno?
Not the bathroom being renovated. If it's the only bathroom in the house, we plan the schedule around rough-in and fit-off stages to minimise downtime. Most clients with one bathroom either stay with family for the 4 to 5 day disruption window, or arrange a portable toilet on site. Two-bathroom homes have no downtime.
Do you supply the tiles, vanity and fixtures?
Two options. KGW can supply everything through trade accounts at trade pricing, with the markup itemised in the quote. Or you can supply your own (delivered to site before we start), and we'll deduct that from the quote. Most clients pick from supplier showrooms in Toowoomba (Reece, Beaumont Tiles, Bunnings Trade) and we coordinate the order. Either way, the spec is locked in writing before the quote is finalised.
What if we want to move the plumbing?
Relocating the shower, vanity or toilet typically adds $1,500 to $4,000 depending on what's behind the wall and how far the new run is. Slab homes cost more than timber-floor homes because of slab cutting and saw work. Worth doing if the layout doesn't work for you, but the simpler decision is often keeping the layout and just upgrading what's in it.
