Small bathroom dimensions (shower, toilet and sink) 6ft x 6ft (1.8m x 1.8m) This is one of the standard layouts for small bathroom floor plans. Half bathroom dimensions (toilet and corner sink, pocket door) 5ft x 3ft (1.5m x 0.9m). The minimum you're allowed by code in the US is 5ft x 2.5ft (1.5m x 0.76m).
You have an old fashioned bathroom vanity at 19 deep which really dont exist in modern times. Modern replacements are 18 deep which are called reduced depth but today everything is 21 deep. 90% of vanity drop in bowl sinks on the market today are 19 wide and 16 deep which would be a cutout size of 18x15.
