Master ensuite renovation cost on the Sunshine Coast
A premium master ensuite on the Sunshine Coast — freestanding bath, double vanity, walk-in shower, marble-look tile — lands between $28,000 and $55,000 installed. The decisions that drive the spread aren’t obvious until you’ve done one: it’s the freestanding-bath plumbing rough-in, the walk-in shower vs framed shower call, and whether the toilet goes concealed-cistern or visible. Each is a $1,500–$8,000 line on its own.

Three decisions that drive ensuite cost on the Sunshine Coast
1. Freestanding bath plumbing reality
A freestanding bath looks effortless but adds $3,000–$8,000 versus a built-in alcove bath of equivalent quality. The reasons: the bath itself costs $1,500–$5,000 more (stone composite, acrylic with metal frame, or solid surface). Floor-mount or wall-mount bath spouts add $400–$1,200 vs standard wall mixers. The plumbing rough-in must come up through the floor (slab cutting on Sunshine Coast slab homes — $800–$1,500) or be precisely positioned in the subfloor for a stilt-build home. And the floor under and around the bath needs continuous tiling around all four sides, which adds 1–2m² of premium tile and labour.
2. Walk-in shower vs framed shower screen
A frameless walk-in shower (no door, just a glass panel) costs $2,500–$4,500 supplied and installed. A standard framed shower screen with hinged door runs $1,500–$2,500. So the walk-in adds $1,000–$2,000 — but it requires more shower space (1.4m+ deep to avoid spray escape), a fall-to-drain that handles open-shower water volume, and grout-line precision in the splash zone. Worth it for the look on a premium ensuite. Skip it on a smaller ensuite under 7m² where space is tight.
3. Double vanity decision
A double vanity (two basins, one cabinet) costs $1,800–$4,500 more than a single 1200mm vanity. Worth it for resale on Sunshine Coast homes over $1.2M — buyers in that bracket expect it in a master ensuite. Not worth it under $800k or in ensuites under 7m² where the second basin crowds the space. Custom joinery (timber veneer or solid timber face) adds another $2,000–$4,000 vs flatpack but is the single most visible quality signal in an ensuite.

Frequently asked questions
What’s the minimum size ensuite for a freestanding bath?
Practically, 6m² is the floor. Ideally 8m²+. A freestanding bath needs 600mm clearance on all sides for proper installation and cleaning, so a 1700mm bath needs at minimum a 2.9m run. Anything smaller and the bath dominates the room visually and physically.
Is a walk-in shower worth the extra $1k–$2k vs a framed screen?
On premium ensuites, yes. The walk-in look is the single biggest “wow” element in a modern ensuite. Two practical caveats: you need 1.4m+ shower depth to control spray escape, and the bathroom needs a properly designed floor fall to handle open-shower water volume.
Concealed cistern toilets — worth it or maintenance nightmare?
Worth it for the look. Maintenance reality: when the cistern needs servicing (usually 8–12 years in for the inlet valve or flush mechanism), access is via a removable panel that adds 15–30 minutes to any plumber’s visit and costs $80–$200 more per call-out. Most owners think it’s worth the visual upgrade.
What’s the on-trend Sunshine Coast premium ensuite tile in 2026?
Large-format porcelain (600×1200mm or 750×1500mm) in marble-look or travertine-look finishes. Costs $80–$150/m² supply, $150–$220/m² installed. The look is calm, expensive, and easy to clean. Bookmark-matched feature walls behind freestanding baths are still popular.
Should I add underfloor heating in a Sunshine Coast ensuite?
Almost never. The Sunshine Coast climate has 10–20 mornings a year where underfloor heating would be genuinely nice. The other 345 days the $3,000–$5,000 spend earns nothing. Save it. If a buyer asks at resale, the lack of underfloor heating won’t shift the sale.
