Bathroom Renovation in Kwai Chung

If the renovation strips the shower area back to the substrate, waterproofing must be redone — a failed membrane is the most expensive bathroom defect there is, because the fix means demolishing finished tiling. Several countries regulate wet-area waterproofing explicitly. Never let a contractor tile directly over an old or damaged membrane.

Relocating a toilet means rerouting the soil pipe and adjusting floor levels; moving a shower means new drainage falls and full re-waterproofing. Either typically adds a meaningful share of the total budget and extra days of work. If your budget is tight, keeping the existing layout is the single most effective cost-saver.

Only in limited ways. Swapping a vanity, toilet, or taps in place works as standalone jobs, but anything touching the shower area, waterproofing, or tiling should be done in one hit — redoing tiles twice or breaking a waterproof membrane to add something later costs more than doing it together.

A straight swap-in-place refit takes about 1-2 weeks; a full renovation with new waterproofing, retiling, and any layout change takes 2-4 weeks. Add waiting time before the start for fixture delivery and trades scheduling — and note that waterproofing membranes need curing days you cannot compress.

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.

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.
