My building requires rear outlet toilets and I have found that really complicates my search for a toilet for a renovation we are doing. We currently have a Gerber Pressure Assisted Dual Flush which I love but my wife thinks is ugly as sin (and it is admittedly big for the space we have so something smaller ie <27-28') would be nice). I have been trying to find something that is either wall mounted or just a bit smaller that has strong flushing power and doesn't streak easily and I have been coming up empty handed. I haven't seen any great reviews of wall mounted toilets (people seem to have problem w either streaking or power). And floor mounted units tend to be too big (the rear outlet Caroma could be a possible exception, but my wife doesn't really like the way it looks). Any thoughts?
