"Larry's team retiled both our HDB bathrooms floor-to-ceiling. Three years on, zero leaks, zero mould. They didn't skip the ponding test — even insisted on the full 24 hours. That alone was worth choosing them."
Direct bathroom renovation contractor for HDB flats, condos and landed homes — proper waterproofing, quality tiling and complete remodel works at honest direct-contractor pricing. No middleman, no commission, no shortcuts.
Larry Contractors is a direct bathroom renovation contractor in Singapore, handling everything from a single-bathroom retiling refresh to a full floor-to-ceiling remodel with new layout, plumbing and electricals. We work across HDB flats, condominiums, and landed properties, and we are HDB-licensed (HB-09-5667H) — required for any wet-area works in HDB bathrooms.
Because we are a direct contractor with our own carpentry factory in Singapore, our bathroom renovation pricing is typically 15–30% lower than going through an interior designer. You speak with the project team directly, your quotation is fully itemised, and the same hands who quote your bathroom are the ones building it.
This is the most important — and most commonly skipped — step in any bathroom renovation. We apply two coats of approved waterproofing membrane to the full floor and 1.5m up the wet walls, then run a mandatory 24-hour ponding test before any tiling begins. Skipping this step is the single biggest reason bathroom leaks appear within 2–3 years of a "cheap" renovation.
Full hack-and-retile work using porcelain, ceramic or homogeneous tiles in your choice of size and finish. We handle the screeding, levelling, tile cutting (including mitred corners for premium finish), grouting and sealing. Floor-to-ceiling tiling is standard in our scope — half-height tiling leaves grout lines exposed to splashes and ages poorly.
Repositioning the toilet, shower, sink, or rain shower head requires re-routing the SP and SW pipes within the screed. We handle the full plumbing scope including water heater installation, instant heater wiring, basin and bidet sprays, drainage gradient adjustment, and pressure testing — all to HDB and BCA standards.
Custom vanity cabinets built in our Singapore carpentry factory — sized to your bathroom dimensions, waterproof construction, with under-counter or vessel basins. We also handle anti-fog mirror cabinets, towel rails, toilet roll holders, robe hooks, shower screens (frameless or framed), and rain shower sets.
Complete removal of old tiles, sanitaryware, false ceiling, and fixtures. For HDB bathrooms in flats built before 2003, we follow the original wet-area positioning to avoid affecting the structural floor slab. Hacking debris is removed daily — your unit doesn't sit with rubble for weeks.
Moisture-resistant gypsum false ceilings with concealed wiring for downlights, cove lighting, and ventilation fans. We install demist mirror wiring, dedicated exhaust fans, and waterproof IP-rated lighting where needed. Proper bathroom ventilation prevents mould and prolongs tile and grout life.
Bathroom renovation cost depends on the property type, the size of the bathroom, scope of work, and your choice of tiles and sanitaryware. Here's a realistic guide based on what we actually quote across Singapore:
HDB Bathroom (Common or Master): $5,000 – $12,000. Full hack-and-retile with new toilet, basin, mixer, shower, vanity and waterproofing typically falls between $7,000 and $10,000. Master bathrooms with rain showers and double basins sit at the higher end.
Condo Bathroom: $8,000 – $20,000. Condo bathrooms are usually larger and often include built-in glass shower screens, more premium tile selections, and additional fittings like demist mirrors. MCST approval is required before works begin (we handle the application).
Landed Property Bathroom: $10,000 – $25,000+. Landed bathrooms range from compact en-suites to full master suites with dual vanities, freestanding tubs and rain showers. Costs scale with size and finish — natural stone, marble, and bespoke vanity work are common premium options.
As a direct contractor, our quotation always itemises the waterproofing, tile cost (per sqm), sanitaryware, vanity, accessories and labour separately. You see exactly what you're paying for — no lumped "renovation package" pricing.
A typical bathroom remodel takes 2–4 weeks per bathroom. If you're renovating multiple bathrooms in one project, they usually run in parallel without extending the overall duration much.
Days 1–2: Hacking. Removal of existing tiles, sanitaryware, fittings and false ceiling.
Days 3–5: Plumbing & electrical re-routing. New SP/SW pipe positions, water heater wiring, exhaust fan rough-in.
Day 6: Waterproofing — two-coat membrane application.
Days 7–8: 24-hour ponding test. Mandatory wait — no shortcuts here.
Days 9–14: Floor screed, wall and floor tiling, grouting.
Days 15–17: Sanitaryware installation, vanity, mirror, accessories.
Days 18–20: False ceiling, lighting, final fittings, cleaning and handover.
HDB Licensed: Required for all HDB bathroom hacking, plumbing and electrical works. Licence No. HB-09-5667H.
Proper Waterproofing — Always: Two-coat membrane and a real 24-hour ponding test. Not negotiable, not skipped to save days.
Own Carpentry Factory: Vanity cabinets and mirror cabinets built in-house in Singapore. No off-the-shelf compromises.
Direct Communication: You deal with the project lead, not an account manager. Faster decisions, fewer miscommunications.
Transparent Itemised Quotes: Tile, sanitaryware, vanity, plumbing and labour separately costed. You can compare line-by-line.
15+ Years Experience: Over 500 residential projects across Singapore, including hundreds of bathroom renovations.
Skipping the ponding test. Some contractors waterproof and tile in the same week to compress the schedule. If the membrane has a pinhole, you only find out years later when water seeps into the unit below. We run the full 24-hour ponding test, every time.
Half-height tiling instead of floor-to-ceiling. Saves a small amount on tiles, but exposed walls behind the basin and shower discolour and crack within 3–5 years. Always go floor-to-ceiling in the wet zones.
Re-using the existing trap and floor gradient. Old HDB bathrooms often have insufficient floor slope and clogged traps. Hacking down to the slab, re-screeding to a proper 1:80 gradient, and replacing the floor trap is the right way — not skimming over the old surface.
Cheap mixer and toilet brands. Sanitaryware is one place where saving $200 today costs you $600 in replacement labour three years later. We recommend mid-range brands (Grohe, Roca, Hansgrohe entry lines) over the cheapest options.
Ignoring ventilation. Singapore's humidity is brutal on bathrooms. Without a proper exhaust fan ducted to outside (not just the false ceiling cavity), mould appears on grout, ceilings and silicone within a year.
HDB Permits: All HDB bathroom hacking, plumbing alteration, and electrical works require an HDB renovation permit. As your licensed contractor, we file the permit application for you.
HDB Wet-Area Position: For HDB flats built before 2003, the wet-area floor is structurally thinner. Toilet and shower positions generally must follow the original wet-zone footprint — we'll advise during the site visit what's allowed and what's not.
Waterproofing Compliance: HDB requires two-coat waterproofing with a mandatory ponding test for all wet area renovations. We document this and provide photos as part of the project handover.
Condo MCST Approval: Condos require MCST approval before bathroom hacking and plumbing work. Common conditions include working hours (typically 9am–5pm weekdays only), deposit, and noise restrictions. We coordinate this with your management office.
Working Hours: HDB allows 9am–6pm weekdays and 9am–1pm Saturdays. No work Sundays or public holidays. Condos are usually stricter — check your MCST house rules.

"Quoted by two IDs at $18K and $22K for our condo master bathroom. Larry quoted $11K direct — same Grohe fittings, better vanity carpentry. Saved 40% and the workmanship is honestly cleaner."
