Is there any toilet system made that will allow an installation on a basement slab that rests on bedrock with no reasonable hope chopping out a hole for a tank and ejector pump. The rise to the main pipe is 3.5′. thanks for any info inc. forgetaboutit.
You could use an upflush toilet. They’re hard to find but they are available. However, they are also quite expensive (~ $700). I’ve read good and bad about them so you may want to do a little research before purchasing one.
Zoeller makes a system called Quick john that has a tank system that mounts on the floor but you will have to frame a raised floor so that the system can be installed. Any plumbing supply house can help you with this.
