The ease of installation is really going to depend on what type of plumbing you have present in your business. If the drainpipe is in the wall, then a floor mount model is not going to be very easy to install, and vice versa. All things considered, however, floor mount models are a bit more straightforward. Since these types of toilets can be set in place before being fully installed, it makes it a bit easier on your back. Another reason that floor mount toilets are easier is thanks to their water lines, especially if they are tanked. Tanked models use smaller water lines that are easier to handle than the larger ones you find with tankless models.
