I put this in a small outdoor pool bathroom.  We needed to replace one that was so elongated and large that it impeded the entry and this was one of the shallowest depths (front of seat to wall measurement) that I could find with the skirted base I was looking for.  We just had it installed (contractor said it was easy) the day before a pool party and I'm happy to report that it fit the bill perfectly!

While it is smaller as some reviewers stated, it only sits at slightly lower than standard seat height.  Perhaps its because of the slightly elongated yet not perfectly round seat?  If so, I could see how larger individuals might find this to be child-sized.  However, if you are looking for a slim-profile, easy to clean toilet for a guest or occasional bath, I would highly recommend.
