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).
There is only one standard size for bathtub drains in the United States. Bathroom options are limitless when it comes to styles of bathtubs, sinks, tile and faucets. When it comes to the plumbing, however, there aren't many choices to be made, thanks to standard industry sizes.
