Dear all, The wet zone in bathrooms have lower floor height compared to the rest of the bathroom (dry zone). Does anyone know if there is a guideline or best practice on the recommended difference in height of floor level between wet and dry zone? Even in my current place, the mbr bathroom has 30mm drop whereas the common bathroom has 23mm drop, which is still tolerable. However, in a new house we've just taken possession, the drops in all the toilets range from 50mm to at least 70mm, which is dangerous for unsuspecting visitors (GF toilet) and older folks. Installing shower partition is not an option due to space constraint, practicality and not to mention having additional maintenance. To clarify which area I'm referring to, please refer to the "wet zone" in the sample image below. Thank you in advance.

QUOTE(Ichighost @ Mar 22 2023, 09:53 AM) actually your current place 30mm / 23mm is an easier spot for new people to stumbled on. 50mm/70mm is significant enough for people to be aware of the drop. two ways of dealing with it. 1- visual treatment..change the tile at the edge of drop to contrast and highlight the drop. or 2- change the blue area to all one big gentle gradient slope. Current place, we didn't face any issues even when first moved in. The tripping or twisting ankle refers to when we walk from dry zone to wet zone. New place - almost twisted ankles on first day of cleaning the house as the floor tiles are same for wet and dry zones. If there's a sort of guideline or best practice, then it's easier for me to nego with the developer to have them rectified by developer. Doing it myself risks voiding the warranty during DLP. |

QUOTE(WaCKy-Angel @ Mar 22 2023, 02:02 PM) Is the wet and dry area same colour? U can try put indicator so ppl will be aware. Personally i prefer deeper so water wont spill out Both use same tiles, that's why more difficult to spot. What kind of indicator do you have in mind? I'm afraid anything that involves hacking is not advisable due to warranty during DLP. |

QUOTE(WaCKy-Angel @ Mar 22 2023, 03:02 PM) Will consider this if everything else fails. Thanks. QUOTE(lowyat101 @ Mar 22 2023, 05:26 PM) can use those construction yellow/red tape. but maybe need to replace once in a while. but to me 70mm is not normal. why not u just submit it in the defect form and see how they explain it? I'm thinking of arming myself with some knowledge about best practice stated somewhere so that they won't tell me "it's normal, no gomen legislation on this, etc". |

QUOTE(ceo684 @ Mar 22 2023, 11:27 PM) 70mm will prevent water rushing out.. it also has some dependency on whether the dry to wet (the bathroom door) has a drop or is largely flush what i would love is to have the slope, slope into the side w drain hole for quick drying.. mostly too flat and tend to pond water puddles  The bathroom door to bathroom does have a drop too. So it's double drop. I understand that the whole bathroom (both shower and berak/basin areas) is supposed to be classified as wet area, hence floor water proofing is done. Anyway, I turned on the shower to max, but water level in the shower zone hardly reached 10mm pun. So 70mm macam serves no purpose imo. |
