Bathrooms are where Bali villas fail first. The climate is brutal on wet areas: constant humidity, heavy use, and the near-universal local habit of tiling straight over bare screed with no real waterproofing membrane underneath. Within a year the water finds the gaps, and you get black mould, lifting tiles, and damp patches bleeding through to the room next door. Our bathroom renovations are built around one non-negotiable: a proper two-coat membrane system, flood-tested before a single tile goes down.
What's Included in a Bathroom Renovation
Strip-Out & Repair
Old tiles, fittings and failed waterproofing removed back to sound substrate, with any rotten or rusted structure repaired first.
Membrane Waterproofing
Two-coat liquid membrane up the walls and across the floor, sealed at every penetration and flood-tested for 24 hours.
Tiling & Stone
Floor and wall tiling, natural stone, terrazzo or micro-cement — laid to fall correctly toward the drain.
Fixtures & Ventilation
New plumbing, vanity, WC, rain shower, glass screen, and the extraction or louvres that keep humidity from rotting the room again.
Why Bali Bathrooms Need More Than a Retile
A retile over old, failed waterproofing is the most common — and most expensive — mistake we are called to fix. It looks fine for a season, then the leak returns and you pay twice. Open-plan and outdoor bathrooms, beloved in Bali villas, raise the stakes further: they take direct rain and need drainage and finishes specified for it. We treat every bathroom as a waterproofing job that happens to have nice tiles on top, which is why ours carry a 5-year waterproofing warranty rather than the usual 12-month nod. For coastal villas we pair this with our waterproofing systems on adjoining terraces.
What a Bathroom Renovation Costs
A standard guest bathroom renovation starts around IDR 35 million; a master ensuite with stone, a freestanding tub and bespoke joinery runs IDR 60–120 million. The variables are size, the finishes you choose, and whether plumbing needs relocating. Most bathrooms take 2–4 weeks, with the waterproofing flood-test and screed cure being the parts we will not rush. See the full pricing breakdown.
