What slope should a shower floor have?
Have you ever checked the slope of your shower floor? Does the water drain well enough?
What does the standard require?
When you install a new shower stall, or move into a new apartment from a contractor,
it is worth checking that the floor really slopes toward the drain as the standard requires.
A faulty slope is a construction defect. It leaves standing water, which is a sanitary hazard: bacteria and fungi, mosquitoes and so on.
In some cases the water also seeps through to the neighbors.
The standard: at least 1% toward the drain
The shower floor must slope at least 1% toward the drain. That is the standard, and anything less than one percent counts as a construction defect. You can measure it yourself with a level, or order a building inspection expert who will check the full range of construction defects in the home (the shower slope is just one small item among hundreds of elements that may be faulty).
What to do if the shower floor does not slope enough
The law requires the contractor to take the shower apart and rebuild it, as part of the inspection period (tkufat bedek) of a new apartment.
Estimated cost of this kind of work: ₪1,500.
