Choosing a toilet bowl for your bathroom renovation

Keep the outlet where it is

The simplest choice. Pick a floor-standing bowl listed for the outlet you have; bowls on this site start at $174.40, bowl only. The rest of the renovation goes ahead around it.

Move to a wall-hung bowl

The waste pipe has to come out of the wall and a concealed cistern and frame go inside it, so the wall and usually part of the floor are hacked, waterproofed and tiled again. Listed wall-hung bowls start at $299.75, bowl only. What the job involves in an HDB flat

Working with your ID or contractor

• Shortlist the bowls you like and send the list to your ID. They see the models and your outlet answers. Your shortlist
• Check the firm is on HDB’s directory. HDB says the renovation contractor you engage must be listed (HDB: looking for renovation contractors). You can search it on our HDB contractor check.
• Ask who does the sanitary plumbing and check their licence on PUB’s licensed plumber search. Fitting or relocating a toilet bowl is work for a PUB licensed plumber (PUB: plumbing works).
• New BTO flat? HDB says you have to wait 3 years before removing wall or floor finishes in the toilets, and need a permit after that to change them (HDB MyNiceHome: renovate your flat).
• The bowl must carry at least 2 WELS ticks (PUB: WELS requirements).
