If you wish to brows the Toto selections, go to the upper right corner of this page where you will find "Toilet Reviews" Click on that and you will go to another page where you will find "Shopping for Toilets" Click that link and find "Toto Toilets". There you can scroll through the many choices you have for Toto toilets. The specifications for each model is included for each model. Elongated toilets are male friendly regardless of the man's height, and are pretty much the bowl selection most buyers made. You should know that toilets come in 3 bowl heights. The old standard, Comfort, and ADA. A person of average height and above usually prefer either the Comfort or ADA. All Toto toilets flush well and do not have clogging issues, so that should not be a concern. Some have better bowl wash than others, and some have the Sanagloss treatment option which helps keep the bowl clean. You can order a Toto from most any plumbing shop even if they don't stock them. As you can see by the number of models, sizes, and colors, it would be virtually impossible to maintain an inventory with every possible toilet available to take home. You will have to know the rough-in requirements for your toilets. This is determined by measuring from the flange bolts on the toilet base to the finished wall behind the toilet, not including molding.
