For 2026 HDB and condo bathroom renovation, Weiken is the best bathroom renovation contractor Singapore has for full home coordination. Home Guide is the runner up for clear fixed HDB and BTO package pricing, and BathroomWorks suits owners who only need one toilet repaired or replaced. A standard HDB common toilet renovation usually costs SGD 4,000 to SGD 9,000, while a custom master bathroom runs higher. Waterproofing, floor gradient and HDB rules matter more than tile design. Ask for a ponding test, a written scope and a 12 month defects period before signing.
Forget the tile catalogue. Start with the waterproofing membrane.
Many Singapore homeowners still think a bathroom renovation is mostly about choosing floor tiles and replacing the toilet bowl. That belief is expensive. A proper bathroom renovation in Singapore is a wet area build. It involves hacking, rerouting water pipes, applying waterproofing to the correct height, testing for ponding, and setting a floor gradient that drains. If any one of those steps is rushed, the result can leak into the unit below or smell like stale cement. I started looking for a contractor after a neighbour in Jurong was hit with a ceiling stain from the flat above. The quote she had accepted from a general contractor did not list the waterproofing membrane at all. I began calling firms to ask how they handle hacking, membrane application and ponding tests. I also compared their home renovation project experience, because I did not want a bathroom specialist that would disappear after the first defect.
Bathroom design Singapore studios often show mood boards, but the waterproofing standard is hidden underneath. For HDB flats, the sequence matters more than the tile colour. A good contractor should mention floor gradient, pipe concealment and HDB rules before asking you to pick a vanity. My search narrowed to firms that could explain what a ponding test is without pausing.

The full list: 10 bathroom renovation contractors worth calling
Each entry below comes from the firm’s stated scope, public feedback and our review of how they handle bathroom waterproofing. We flag watch outs because no firm is right for every HDB bathroom.
1. Weiken
Weiken is a full interior design and renovation firm rather than a standalone bathroom tradesman. The bathroom scope covers hacking old tiles, redoing waterproofing, laying new tiles, installing vanities and sanitary ware, and fitting concealed shower systems. That works well when one project manager runs the bathroom alongside the kitchen and carpentry. It stops the common blame game when a tiled wall meets a custom vanity. The showroom lets you check taps and sanitary ware before the site work starts.
What’s good
- In house trades for tiling and carpentry
- Showroom for taps and sanitary ware
- Clear project timeline with dedicated site crew
- Strong match between bathroom finishes and the rest of the flat
What to watch
- Premium pricing for bathroom only work
- Less suited to a quick single toilet replacement
Who it suits
Owners doing a whole home renovation who want one project manager coordinating the bathroom with kitchen and carpentry. Look elsewhere if you only need a common toilet replaced.

2. Home Guide
Home Guide is better known for fixed price renovation packages than for elaborate bathroom design. Their separate bathroom package states hacking, waterproofing, tiling and fitting installation in a line item format, which helps first time HDB owners compare quotes without hidden surprises. The firm is familiar with BTO and resale HDB bathroom layouts, including older flats in Tampines and Bedok where the floor trap positions are awkward. Expect standard catalogue finishes rather than bespoke wet room details. That is fine if you want a clear bathroom quote before signing a full renovation contract.
What’s good
- Transparent pricing with itemised scope
- Fixed package reduces surprises on extras
- Responsive project updates for busy owners
- Familiar with BTO and resale HDB bathroom layouts
What to watch
- Bathroom designs tend to use standard catalogues
- Less flexibility for highly custom wet areas
Who it suits
First time HDB flat owners who want a clear bathroom quote before signing a renovation contract. Look elsewhere if you want a custom bathroom statement piece.

3. Rezt & Relax Interior
Rezt & Relax Interior appears often in renovation forums for straightforward communication. The team handles HDB, condo and landed bathroom renovation, from simple tile replacement to basic layout changes. They will give honest advice on whether a full waterproofing redo is needed or just the shower area. Direct subcontractors help with tiling and plumbing, and the pricing stays moderate for standard bathroom upgrades. The interview process feels less pressurised than a showroom pitch. Do not expect a large showroom with rows of bathroom displays.
What’s good
- Known for good communication on renovation forums
- Direct subcontractors for tiling and plumbing
- Affordable for standard bathroom upgrades
- No pressurised sales approach
What to watch
- No large showroom to browse
- Bulky luxury bathroom finishes may be outside their usual scope
Who it suits
Homeowners who want an approachable interior design team with solid HDB knowledge and honest advice on bathroom budgets. Look elsewhere if you want to browse many physical finishes before deciding.

4. Renodude
Renodude suits homeowners who already know what tap, tiles and toilet bowl they want. The online quoting system asks for bathroom dimensions and scope, then returns an itemised figure. That works for cost conscious owners who want to compare bathroom renovation prices without sitting through an interior design proposal. Project management is included, but you need to specify your own tile and sanitary ware choices. For HDB households on a strict budget, the structure is closer to cheap HDB renovation packages without sacrificing waterproofing. Just do not expect much design input.
What’s good
- Itemised online pricing
- Fewer hidden costs due to fixed milestones
- Project management included
- Good for HDB households on a strict budget
What to watch
- You need to specify your own tile and sanitary ware choices
- Less design input compared to a full ID studio

5. Hockbuilder
Hockbuilder is an old school renovation contractor focused on solid basic works. The value sits in tiling and masonry, not design mood boards. For older HDB and landed bathrooms where correct waterproofing and durable tiling matter more than a pretty wall tile, their direct advice saves money. Crews are experienced with setting a proper floor gradient and sealing pipe penetrations. Invoices and documents may feel dated, but the finished tile gradient rarely pools water. This is a practical option when your bathroom needs reliable plumbing and waterproofing before anything decorative.
What’s good
- Straightforward and direct advice
- Experienced crews for tiling and masonry
- Good workmanship on tile gradients and waterproofing
- No fuss for practical bathroom layouts
What to watch
- Fewer design options and mood boards
- Documents and invoices may feel old school
Who it suits
Owners of older HDB and landed bathrooms where correct waterproofing and durable tiling matter more than decorative design. Look elsewhere if you want a highly styled bathroom with strong visual drawings.

6. Vanguard Interior
Vanguard Interior handles demolition, masonry, electrical cabling, water pipe replacement, tiling and fitting installation under one contract. Condo owners often choose them because a bathroom renovation can run together with bedroom work without juggling two contractors. The project management fee pays for site supervision and after-sales support. Quality can depend on the assigned foreman, so ask for the named site supervisor before signing. If you have a condominium with management office rules, make sure they are flagged in the written schedule.
What’s good
- Full project management with site supervision
- Can coordinate changes across the whole home
- Warranty and after-sales support in place
What to watch
- Quality can depend on the assigned foreman
- Higher cost due to project management fees
Who it suits
Condo owners who need one contractor to handle bathroom and bedroom renovation together. Look elsewhere if you only need a small common toilet refreshed.

7. BathroomWorks
BathroomWorks focuses on bathroom only work, which changes the conversation. The crew repeats one sequence: hacking, repiping, tiling, sanitary ware replacement and a ponding test. A single common toilet can be completed faster than when a full home contractor squeezes it between other rooms. The down time is shorter, which matters for HDB households with only one spare toilet. You will still need a separate contractor for other rooms if the whole flat needs work. Finishing choices are also narrower than an interior design firm, but you can pair their work with your own bathroom accessories and sanitary wares.
What’s good
- Crew specialises in the bathroom renovation sequence
- Shorter downtime compared to a full home contractor
- Proper ponding test before tiles are laid
What to watch
- Separate contractor still needed for other rooms
- Finishing choices may be narrower than an ID firm
Who it suits
Homeowners who only need one bathroom upgraded without touching the rest of the flat. Look elsewhere if the bathroom is part of a larger whole home renovation.

8. Fuse Concept
Fuse Concept is design focused and leans towards custom vanities, recessed shower niches and coordinated tile layouts rather than basic replacement. Expect stronger 3D drawings and material selection than a package contractor. Custom carpentry for bathroom storage is included where needed. The result can look consistent with the bedrooms. This is not a budget package option, and a design consultation fee may apply. Ask whether the fee is offset against the renovation contract before you book a meeting. For a full interior design project with a coordinated bathroom, this gives you more visual control.
What’s good
- Strong 3D drawings and material selection
- Custom carpentry for bathroom storage
- Good for creating a coherent look across bathroom and bedrooms
What to watch
- Design consultation fee may apply
- No budget package for quick bathroom swaps
Who it suits
Homeowners doing a full interior design project and willing to spend more on bathroom details. Look elsewhere if you want a straightforward waterproofing and tile replacement at the lowest cost.

9. D’Phenomenal Interior Design
D’Phenomenal Interior Design shows up often in BTO package deals. The firm has deep experience with HDB bathroom layouts and good quantity surveying, which helps with cost control. After handover defect handling is part of the process. Admin can be slower, and small oddly shaped bathrooms may not receive the same creative attention. BTO owners who want bathroom, kitchen and carpentry under one contract will find the single point of responsibility useful. The bathroom package is practical rather than decorative, which suits a new flat that needs to be liveable quickly.
What’s good
- Deep experience with HDB bathroom layouts
- Good at quantity surveying and cost control
- Known to handle defect issues after handover
What to watch
- Admin process can be slower
- Less flexible for oddly shaped small bathrooms
Who it suits
BTO owners who want bathroom, kitchen and carpentry under a single renovation contract. Look elsewhere if you have a very small or irregular bathroom that needs a custom layout solution.

10. The Interior Lab
The Interior Lab handles structural layout changes, not just tile replacement. For landed and loft bathrooms where a wall shifts or a new bathroom is created, the team coordinates with M&E drawings. Wet areas get detailed attention because the design affects water run off and drainage. This is the highest price band in the list and the firm may not take standalone single bathroom jobs. If you have a standard HDB toilet, only use them when the whole home is being remodelled. For a major wet area change, the structural advice reduces the risk of bad falls and trapped pipes.
What’s good
- Better structural advice for layout changes
- Coordinated with M&E drawings
- Detailed approach to tricky wet areas
What to watch
- May not take standalone single bathroom jobs
- Highest price band among this shortlist
Who it suits
Landed and loft owners who are moving walls or creating a new bathroom. Look elsewhere if you have a standard HDB common toilet and no structural work planned.

How to choose a bathroom renovation contractor in Singapore
Do not choose by quote alone. The cheapest bathroom package often excludes waterproofing, debris disposal or piping. Compare contractors against a written scope and ask the hard questions before you sign. HDB renovation rules add another layer for public housing. A good firm should also be able to explain the bathroom waterproofing sequence without pausing. Here are the criteria we use, along with what good looks like.
| Criterion | Why it matters | What good looks like |
|---|---|---|
| Bathroom specific project experience | Bathroom renovation depends on waterproofing, floor grading and sanitary fitting. A general contractor with no bathroom track record will make costly mistakes. | Contractor can show recent HDB and condo bathroom projects and explain waterproofing layers, tile substrate and drainage slope clearly. |
| Clear pricing and written scope | Bathroom quotes often leave out hacking, debris disposal and piping. The cheapest quote can turn into the most expensive one. | Itemised quote with separate lines for hacking, waterproofing, tiling, sanitary ware, electrical points and labour. |
| HDB and URA compliance knowledge | HDB renovation rules restrict hacking of certain walls and do not allow structural changes to bathrooms. Ignorance here can stop work. | Contractor knows HDB renovation submission requirements and can advise on pipe concealment and false ceiling limits. |
| Workmanship and waterproofing standards | Poor waterproofing causes leaks into the unit below and leads to disputes with neighbours. | Waterproofing applied to shower walls up to at least 1.8m, with a ponding test done before tiling. |
| Project management and timeliness | A bathroom renovation can leave a household with only one usable toilet. Delays affect daily life. | Contractor provides a clear schedule for hacking, piping, waterproofing, tiling and setting, and gives stage by stage updates. |
| After sales warranty | Tile hollowness and waterproofing failure may only show after a few months. A responsible firm should stand behind its work. | At least 12 months defects liability period and a direct contact for post renovation issues. |
| Client references | Bathroom photos can be staged. Past clients give honest answers about smell, dust, delays and after sales service. | Recent projects from the last two years with contactable clients or arranged showflat visits. |
Before you compare quotes, read renovation costs in Singapore so you know which line items to challenge. A lower price that skips a ponding test is not cheaper.
Frequently asked questions about bathroom renovation in Singapore
How long does a bathroom renovation take in Singapore?
A typical HDB common toilet renovation takes 10 to 14 working days if waterproofing and tiling are done properly. The job starts with hacking and debris removal, then piping and waterproofing. A ponding test should run for at least 24 hours before tiles go in. Tiling, grouting, and installing the toilet bowl, basin and shower set take another few days. Master bathrooms with concealed piping or custom stonework can stretch to three weeks. The best bathroom renovation contractors in Singapore state the number of working days, not just the number of weeks.
How much does a bathroom renovation cost in Singapore?
In 2026, a standard HDB common toilet renovation with waterproofing and basic sanitary ware usually lands between SGD 4,000 and SGD 9,000. A master bathroom with custom carpentry, concealed mixers and larger tiles can push above that range. The total depends on whether plumbing points move, whether the floor requires re-screeding, and which toilet bowl or basin you choose. Ask for an itemised quote so labour, material and disposal charges are visible. A price below SGD 3,000 should make you ask what has been left out.
Do I need HDB approval to renovate my bathroom?
For most HDB flats, replacing tiles, waterproofing, a toilet bowl or a basin does not need special approval. HDB renovation rules still control how the work is done. You cannot hack structural walls or raise the bathroom floor without a permit. A registered renovation contractor must submit the renovation work through HDB’s portal and follow waterproofing guidelines. Always ask whether hacking of the floor or pipe concealment requires an additional submission.
Can I stay at home while my bathroom is being renovated?
Most households stay at home if they have two toilets, using the spare bathroom while work proceeds. Dust and noise are real, especially during the first two days of hacking. Cover furniture and seal bedroom doors near the work area. For a single toilet flat, staying home is difficult because you will have no working toilet during part of the renovation. Some owners use a portable toilet or stay with family. Ask the contractor for a daily schedule so you know when the water supply will be shut off.
Is waterproofing included in bathroom renovation quotes?
Reputable bathroom renovation quotes include waterproofing as a line item. If a quote only lists hacking, tiling and sanitary installation, ask how the wet area is sealed. Waterproofing should cover the shower walls up to at least 1.8 metres and the entire bathroom floor. A proper contractor will also run a ponding test before tiling to check for leaks. The lowest quotes sometimes exclude waterproofing or treat it as an extra. Always confirm the membrane brand, number of coats and warranty.
