Bathroom/Toilet Renovation Cost in Singapore

A full bathroom or toilet renovation in Singapore typically costs between S$5,000 and S$15,000 per toilet for a standard HDB unit, and often S$10,000 to S$25,000 or more for a condo or a larger, higher-spec job. The exact figure depends on the size of the space, whether you are doing a cosmetic refresh or a full hack-and-replace, and the grade of tiles, sanitary ware and fittings you choose.

These are working ranges, not fixed quotes. A light update that keeps the existing layout and only swaps the toilet bowl, basin and a few tiles can come in under S$5,000, while a resized, waterproofed, fully re-tiled bathroom with premium finishes can run well past S$25,000. The only way to know your number is to have a contractor measure the space and price the specific scope.

What is included in a typical toilet renovation cost?

Most quotes bundle several trades together, which is why a single toilet can add up quickly. A full renovation usually covers demolition (hacking old tiles and fixtures), waterproofing, new floor and wall tiles, plumbing and drainage adjustments, electrical points, and installation of new sanitary ware and accessories.

Cheaper quotes often exclude items you will still need to pay for, so read the scope carefully before comparing prices.

• Hacking and disposal of old tiles, bowl and basin
• Waterproofing membrane on floor and wet walls
• Supply and lay of floor and wall tiles
• Plumbing, drainage and concealed pipe works
• Electrical points for heater, lights and exhaust fan
• New toilet bowl, basin, tap, mixer, shower set and accessories

How much does an HDB toilet renovation cost?

For a standard HDB toilet, a full renovation commonly lands between S$5,000 and S$12,000 per toilet, with many households ending up around the S$7,000 to S$10,000 mark once mid-range tiles and fittings are included. A three-room or four-room flat with two toilets can therefore see a combined bathroom spend well into five figures.

HDB has specific rules that affect cost and timing. Waterproofing and hacking of the original bathroom floor screed is generally restricted in the first three years for new flats, and any work must follow HDB renovation guidelines. Your contractor should factor permits and approved methods into the quote.

How much does a condo bathroom renovation cost?

Condo bathrooms tend to cost more, commonly S$10,000 to S$25,000 per bathroom, and higher for large master ensuites or luxury finishes. The gap comes from bigger floor areas, more elaborate layouts, feature walls, frameless glass shower screens, and premium imported sanitary ware.

Condos also add management-office requirements: approved renovation hours, refundable deposits, protection of common corridors and lifts, and sometimes hacking restrictions. These do not always show up as line items, but they influence scheduling and labour.

What factors change the final price the most?

Two bathrooms of the same size can differ by thousands of dollars. The biggest swing factors are how much you hack and rebuild, the quality of materials, and whether the layout or plumbing points are moved.

If you are trying to control budget, keeping the existing layout and drainage positions is usually the single most effective saving.

• Scope: cosmetic refresh versus full hack-and-replace
• Tile grade: standard ceramic versus large-format or imported tiles
• Sanitary ware: builder-grade versus premium brands
• Layout changes: moving the toilet, basin or floor trap raises plumbing cost
• Waterproofing and re-screeding, which is essential but adds cost
• Extras: rain shower, heated water, niche shelves, vanity carpentry, glass screens

How long does a bathroom renovation take?

A single toilet usually takes about two to three weeks of on-site work, though the full timeline from confirmation to completion is often longer once tile selection, material lead times and drying periods for waterproofing are included.

Rushing the waterproofing curing time is a common cause of leaks later, so a slightly longer schedule is normal and worth it for a wet area.

How can I get an accurate quote for my toilet?

Because so much depends on the actual space, the reliable path is a site visit where a contractor measures the bathroom, checks the existing plumbing and confirms the scope you want. Ask for an itemised quotation so you can see exactly what waterproofing, tiling, plumbing and sanitary ware are covered.

If you are planning a toilet or bathroom renovation, our team handles the full scope from hacking and waterproofing to tiling, plumbing and fitting installation, and can give you a clear, itemised quote for your unit. Getting two or three comparable quotes on the same scope is the best way to judge whether a price is fair.

Frequently asked questions

Is it cheaper to renovate one toilet or two at the same time? Doing both together is usually more cost-efficient per toilet, since the contractor mobilises once and shares setup, disposal and labour across both. You also finish the disruption in one go rather than repeating it later.

Do I really need waterproofing if the old one still looks fine? Yes. Once you hack the floor for a full renovation, fresh waterproofing is essential to prevent leaks into the unit below, and skipping or rushing it is a leading cause of expensive repairs. Treat it as non-negotiable, not an optional upgrade.

Can I keep my existing tiles to save money? Sometimes. If the tiles are sound and you only want a cosmetic update, you can overlay or retain them and swap fittings, which lowers cost. But if there are cracks, hollow tiles or suspected leaks, hacking and re-waterproofing is the safer choice.

Why are contractor quotes so different for the same toilet? Quotes vary because the included scope, tile and sanitary ware grades, and waterproofing method differ. Always compare like for like on an itemised basis rather than picking the lowest headline number.
