Step 2: Design the Commercial Bathroom Layout

The second bathroom remodel step is to consider the layout for your commercial bathroom remodel and the unique needs of your business. For example, if your commercial bathroom is in a gym and locker room, spa, or hotel, you will need to consider the layout and space you have to include showers and bathtubs, while an office space, restaurant, church, school, or public bathroom facility may need to focus on privacy and supporting heavy use and regular traffic.

If you have a larger space, or a luxury bathroom space intended for people to sit, relax, and contemplate the finer things in life, you may consider adding commercial bathroom furniture such as sofas and seating arrangements, as well as small tables as well as extra space with commercial bathroom countertops.

Calculate the Commercial Bathroom Dimensions

To calculate your commercial bathroom dimensions, first choose a starting point, measuring each wall from one corner to the other —  working clockwise. If your restroom is an irregular shape, divide the floor plan into rectangles and measure each rectangle individually, then add up the sums.

Next measure the height of the restroom from floor to ceiling. Make note of all doors and windows, and make sure to mark down any permanent fixtures.
