hi
as i understand it, most thai architects/contractors recommend 10 cm lower for bathroom floors and maybe also for the patio outside.
i was wondering whether it would be sufficient to just do 1:200 sloping to contain the spread of water. if this is not possible, i would like to lower the floor by a minimum in combination with a slope of 1:200
i would like to enquire whether 1-2 cm lower in combination with a 1:200 slope would be sufficient.
thanks
