Toilet renovation for HDB and condo bathrooms, with the price fixed first

A toilet renovation in Singapore packs a lot into one small, wet room: hacking, waterproofing, re-routed pipes, tiling, sanitary fittings, a vanity, a shower screen and ventilation. Best Interior Design puts every one of those items in one itemised quote, builds the vanity in our own factory, and fixes the price before the first tile comes off the wall.

What a Toilet Renovation Includes, Item by Item

A full toilet renovation covers protection, hacking out old tiles and fittings, waterproofing, re-routing pipes where the layout changes, wall and floor tiling, sanitary fittings, a vanity cabinet, a shower screen, ventilation and lighting, then sealing and a final clean. Each item sits on its own line in your quote, so nothing is left vague.

  • Protection for your floors and the route from the lift to the toilet.
  • Hacking of old wall and floor tiles, the old vanity, fittings and accessories.
  • Waterproofing over the floor and up the walls before any tile goes down.
  • Plumbing points moved or replaced where your new layout needs it.
  • Wall and floor tiles, with a slip-resistant tile on the floor.
  • Sanitary fittings: toilet bowl, basin, taps, shower set and accessories.
  • A vanity cabinet built in our factory, and a glass shower screen.
  • An exhaust fan where the toilet has no window, plus new lighting.
  • Sealing, testing and a final clean.

Why Waterproofing Is the Line Never to Cut

Waterproofing is the layer under your tiles that keeps water in the toilet and out of the walls and the flat below. Once tiled over, nobody can see it, which makes it the easiest line to cut and the costliest to fix later: a leak means hacking up your new tiles and starting again.

Whoever you hire, check four things on the quote:

  • The waterproofing product, named on the line, not just the word waterproofing.
  • Where it goes: the whole floor, turned up the walls, and higher around the shower.
  • Time to cure, and a water test before any tile is laid.
  • Who answers for a leak after handover, in writing.

On our quotes, waterproofing is its own line, laid by our licensed trade partners after the hacking and before the tiling.

Old HDB Toilet Renovation: What Changes in an Older Flat

Older HDB toilets often come with worn pipes, dated tiles and poor ventilation. Renovating one usually means hacking the old finishes, laying new waterproofing, replacing pipes that show their age and fitting an exhaust fan. We check the toilet on site during the free measurement and price only what it actually needs.

In a 4-room HDB, renovating the common toilet and the master bathroom together means one round of hacking, one set of approvals and one handover, instead of living through the dust twice.

HDB Toilet Renovation Rules to Check Before Hacking

HDB requires flat owners to use a contractor listed in its Directory of Renovation Contractors, and some toilet works, such as hacking floor finishes or walls, need HDB approval before they start. Condo toilets follow the MCST's by-laws instead, and we prepare that paperwork for you. Either way, the rules go into the plan before work starts.

HDB sets out which works need approval on its renovation guidelines page. As a design-and-build renovation contractor, we check every toilet plan against those rules, and noisy works such as hacking follow HDB's permitted hours.

Toilet Renovation Prices, From One Toilet to Two

A toilet renovation with us starts from $6,500 per toilet, with 9% GST included. The whole order needs to come to $10,000 or more, so a single toilet is paired with a second toilet, the kitchen or other works. The final price depends on the tiles, fittings, vanity length and how much hacking the room needs.

Rooms and works add up: two toilets, or a toilet and the kitchen, clear the minimum together, and running them in one schedule keeps the disruption to a single stretch. Our kitchen renovation works fit the same schedule, and the renovation cost guide shows how bathrooms sit inside a whole-home budget.

A Vanity Built in Our Factory to Fit Your Wall

Your vanity cabinet is built in our own factory in Admiralty, on BestPly E0 plywood with at most 0.5 mg/L of formaldehyde, a third of the E1 limit. Because we build it, it is made to the width of your wall and around your pipes and basin, not a stock size with a gap at one end.

Vanity cabinets are priced from $151 per foot run on our published rate card, in laminate finishes, with the basin and countertop on their own lines.

When Your New Toilet Is Ready, in Writing

We do not promise a number of days before we have seen your toilet. Once the design is signed off and the site is measured, the handover date goes into your contract, and if we miss it, we pay you $5,000, taken off what you still owe at handover. Changes you ask for can move it.

The on-time guarantee sets out how the date is fixed and what else can move it, such as an HDB permit or MCST approval that arrives late.

Frequently Asked Questions

What Does a Toilet Renovation Cost in Singapore?

With us, a toilet renovation starts from $6,500 per toilet, with GST included. The final figure depends on the tiles, fittings, vanity length and how much hacking the room needs, and every item is listed on its own line in your quote.

Can I Renovate Just One Toilet?

Yes, as long as the whole order comes to $10,000 or more. A single toilet from $6,500 can go in with a second toilet, the kitchen or other works in the same job.

Do I Need HDB Approval for a Toilet Renovation?

Some works do, such as hacking floor finishes or walls, and HDB requires you to use a contractor listed in its Directory of Renovation Contractors. We check your toilet plan against HDB's rules before any work starts.

Is Waterproofing Needed if I Only Change the Tiles?

If the old floor tiles are hacked off, yes: the layer under them is disturbed and has to be laid again before new tiles go down. Laying new tiles over the old ones is sometimes possible, and we tell you on site whether your floor suits it.

How Long Does a Toilet Renovation Take?

It depends on how much hacking, re-piping and waterproofing your toilet needs, so we set the dates after the site measurement. The handover date then goes into your contract.

Can We Use the Toilet During the Renovation?

Not the one being worked on. If your home has two toilets, we can plan the works so one of them stays usable for as long as possible.
