Cairns suburbs we cover
Cairns North, Westcourt, Manunda, Trinity Park, Mount Sheridan, Redlynch.
Standard main bathroom — full renovation, same layout
Complete strip-out and demolition ($1,075–$3,250), new waterproofing with certificate ($755–$3,775), floor and wall tiling ($3,025–$8,100), new vanity ($540–$3,775), toilet ($430–$1,300), frameless shower screen ($865–$2,700), tapware and mixers, bath replacement or resurfacing, plumbing rough-in ($2,150–$5,400), electrical, and painting and finishing. This is where most Cairns bathrooms land. Keeping the existing layout keeps the plumbing cost down.
Premium bathroom — layout changes, high-end finishes
Everything above, plus: a freestanding bath ($1,625–$5,400 installed), underfloor heating, a custom joinery vanity, a frameless glass shower screen ($865–$2,700), premium floor-to-ceiling porcelain tiles, a heated towel rail ($380–$1,300 installed), a smart toilet, niche shelving, and designer lighting. Relocating plumbing for a new layout adds to the plumbing rough-in ($2,150–$5,400), and structural work to expand the bathroom footprint is priced on top.
Wet room conversion
An increasingly popular option in Cairns, wet rooms eliminate the shower screen by tanking the entire floor. This requires meticulous waterproofing (the entire floor acts as a shower base) and precise falls for drainage. The extra cost over a standard bathroom is mainly in additional waterproofing and tiling labour (on a standard bathroom, waterproofing costs $755–$3,775 and tiling $3,025–$8,100). The result is a spacious, accessible bathroom that works particularly well in compact spaces.

What Affects Bathroom Renovation Costs in Cairns
Humidity and drying time
Cairns sits in National Construction Code climate zone 1, hot and humid in summer and warm in winter (ABCB climate zone map), and an average February brings 16.0 days of rain (BOM, Cairns Aero). Moist air slows drying and curing and feeds mould, so ask how the bathroom renovator deals with moisture, ventilation and drying time on your job.
Getting rid of the waste
Cairns is in Queensland's regional waste levy zone, $100 a tonne for 2026-27 (Queensland Government). Portsmith Transfer Station takes domestic asbestos only in small, double-wrapped and labelled bundles under 175 kg (Cairns Regional Council), so bigger asbestos loads go through a licensed removalist.
Queensland licensing
In Queensland, building work worth $3,300 or more needs a QBCC licence, and plumbing, drainage and gas work need one at any value; electricians are licensed through the Electrical Safety Office. Check the bathroom renovator's number on the QBCC licensee register before a deposit changes hands.
What Cairns homes look like
Separate houses make up 71.0% of occupied Cairns dwellings, below the 74.8% across Queensland, while flats and apartments are 17.0%, well above the state's 12.5% (ABS 2021 Census). Apartment jobs bring body-corporate rules, lifts and parking into the price; a house brings yards, roof space and longer runs.
