I live in the highest floor. I do not know how many floor traps in hdb toliets.

I just had my resale flat fully renovated. I faced problem with my renovation contractor.

My common toliet & master toliet only hava one floor trap cover at dry area & one floor waste cover at shower area. I complained the floor waste strain is too small & sealed. I asked them to rectify by replacing it with a wider floor waste strain that can be opened just like the floor trap cover at dry area.

He said it cannot be done & restricted by HDB ruling of 5mm cement (i dunno what) requirement. And also said my toliet only have one floor trap pipe & the only solution was that floor waste at my shower area as my shower area as a shower screen & separated from dry area.

He said if i want, he remove that floor waste at shower area & let water flow down through the floor trap at dry area.

He also said some newer flats have two floor traps & mine older one has only one floor trap.

anyond hv any advice on my situation?

Hi,

You might want to refer to HDB link 

http://www.hdb.gov.sg/cs/infoweb/residential/living-in-an-hdb-flat/renovation/guidelines/building-works

In this link, look at "Replacement of existing bathroom/ toilet floor finishes after first 3 years from the date of completion of the block.", Those are the requirements.
