Key takeaways
- Most bathroom renovation jobs in Hong Kong land between HK$30,000–HK$350,000 — known locally as bathroom renovation (浴室裝修).
- Hong Kong bathroom renovations must fit the building's management rules (deposit, hours) and use WSD-licensed plumbers for water works and EMSD-registered workers for electrics; drainage alterations typically fall under the Buildings Department minor works control regime. Leaks into flats below are the classic dispute, so waterproofing documentation matters.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Hong Kong typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a bathroom renovation pro in Hong Kong
- Notify building management, pay the renovation deposit, and confirm permitted working hours before booking trades
- Use a WSD-licensed plumber for water supply works and an EMSD registered electrical worker for wiring
- Check whether any item falls under the Buildings Department minor works regime (drainage alterations commonly do) and use a registered contractor for it
- Get quotes itemized: demolition, waterproofing, tiling per sq ft, plumbing points, and fixture supply
- Confirm waterproofing scope and curing time in the schedule — rushed membranes cause the leak disputes common in older buildings
- Stage payments and retain 5-10% until after a leak-free first weeks of use
Red flags
- Ignores building management approval or working-hours rules
- Drainage changes proposed with no registered minor works contractor
- No waterproofing line in the quote
- Demands most of the payment before tiling starts
- No verifiable past projects in similar buildings

Frequently asked questions
What should I check at handover of a renovated bathroom?
Run every fixture: check drainage speed, look under the vanity for weeps, confirm the shower floor falls to the drain (pour a bucket and watch), check grout lines are even and silicone is continuous, and test the extractor fan. Photograph everything and get the waterproofing product and warranty terms in writing before releasing final payment.
Is tiling over existing tiles ever OK?
It can work on sound, well-bonded wall tiles and saves strip-out cost, but it fails on floors with movement, adds thickness that fouls doors and fittings, and hides the condition of the substrate and membrane. Most renovators strip back in wet areas — if a contractor proposes tile-over-tile in the shower zone specifically, treat it as a cost-cutting red flag.
How much deposit should I pay a bathroom renovator?
Around 10-20% is normal, sometimes more where custom vanities or imported fittings must be ordered up front — in that case pay the supplier invoice share, not a round 50%. Hold 5-10% back until the room has been used for a week or two and the snag list (grout gaps, silicone, door alignment) is closed.
What is the correct order of works in a bathroom renovation?
Strip-out, then first-fix plumbing and electrics (pipes and cables in walls), then substrate preparation and waterproofing, then tiling, then second-fix (toilet, vanity, taps, shower screen, lights), then silicone and snagging. If a quote or schedule doesn't follow this order, question it — out-of-sequence work is how leaks and redone tiles happen.
How much does a bathroom renovation cost in Hong Kong?
A standard full bathroom renovation typically runs HK$60,000-HK$130,000, with basic refreshes from about HK$30,000-HK$50,000 and high-spec projects HK$150,000-HK$350,000. Small bathroom footprints don't make it cheap — demolition, waterproofing, and licensed trades dominate the cost.
Who is liable if my renovated bathroom leaks into the flat below?
You are, as the flat owner — water seepage cases between flats are among Hong Kong's most common building disputes, handled via the Joint Office (FEHD/BD) and civil claims. Insist on a named waterproofing system, proper curing time, and a written warranty from your contractor; it's your main protection.
