Raised seat for portable toilet

[New Comer]

Is there a raised seat for portable toilet out there? I am a tall person and am having trouble with the portable toilet used in RV. I would like to use a raised seat (like 4") to add to the toilet seat when I sit on it. Most raised seat out there are for the regular toilet; they are too big in size to fit the portable toilet (the plastic kind). Can someone help me with this? Thanks.

What about putting something underneath?

And some toilets are taller than others.

if you are talking a porta potti just put something under it to block it up. if you are talking a built in RV toilet, you would remove the toilet, extend the down pipe, and build a box for the toilet to sit on. then reinstall the toilet. highdesertranger

Toilet risers are a thing - usually available as a safety product for older folks in sticks n' bricks environments. See Amazon search link:

However I'm not sure how those affix (for a mobile environment) and, as others have said, if the toilet is portable then it would be easier to put something underneath it.

If it is the built in rv toilet and you don't want to build a box under it, there are taller rv toilets that can be installed. Thetford seems to be one of the better brands.
