Q: In our home we still have two original wall-hung toilets from the 1960s. I want to replace them with more efficient toilets to save water. How involved is this job, and where do you even find wall-hung toilets? Also, the toilets seem very low to the floor, would it be very expensive to raise them when we replace them?
A: First, good job for wanting to replace your old water guzzling toilets with new efficient toilets!
Now, to the complicated part about working with wall-hung toilets. Wall-hung toilets are usually found in commercial applications, but you do see them in homes from time to time.

I recommend working with a licensed plumber when changing wall-hung toilets, especially with older ones, with which you need to fit the new toilet bowl to the existing mounting brackets and piping. A good plumber can inspect the job to see if the in-wall connections and hanging equipment can be reused and if new toilets are available that can work with your present setup.
If you get a little luck, new efficient wall-hung toilets may be able to be installed to your existing wall mounts and plumbing. If not, then you may have to do a complete in-wall rough-in job to install your new wall-hung toilets, and that can get expensive. But, since you would be starting new, you can raise the toilet bowl height. At least for a higher price you’ll get your higher toilets.
