Washroom Calculators

With our continuing commitment to helping the design community these tools have been designed to assist architects, builders, and facility managers in quickly and accurately calculating the minimum washroom requirements based on use of a space to meet the requirements of the Ontario Building Code.

By inputting the necessary information, such as the use of the space and number of occupants or floor area, these calculators will generate the required minimum number of washrooms and fixtures needed to comply with the Ontario Building Code.
