Question:
I need to replace a Thetford 42050 Toilet. It appears that specific model number is no longer available. What are the direct replacements for that model? I have a Jayco 286BHSW. Let me know my options without making any modifications. Thanks

Hey David,
It looks like that Thetford is their Aqua Magic II model. We do not have a "direct" replacement for that specific model number you gave however we do have that same style toilet. There are 2 options based on your rough-in measurement. This is the measurement form the wall to the center of the floor flange. If yours is a 9-1/2" you will want to go with # TH65SE, if it comes out to be 11" you will need # TH59SE
These are both standard height, round ceramic bowls in that same Aqua Magic style of yours.

Hey David, how did things go with measuring the rough-in for your Jayco’s toilet replacement? Were you able to find that one of the Aqua Magic options fit without any changes? Your update could make it easier for others replacing the same Thetford model.
