From the Bathroom Remodeler #1 in Santa Monica. When planning a layout for your bathroom remodeling project in Los Angeles consider the size of the bathroom and the location of the plumbing fixtures. The National Kitchen and Bath Association recommends that there should be at least 30 inches of clear floor space in front of all fixtures. It is also recommended that there should be at least an 18-inch gap at the side of a toilet and 30 inches in front so that it is easy to clean and use.
