Hello Yes would need to inspect it fully to give an accurate answer but it will depend on how the waste is carried away- if its a large diameter pipe (4") then you should be able to change it for a normal toilet, if the pipework is small bore (22, 32 or 40mm) and/or goes a long way hozizontally or vertically then it will need to be a macerator type. Best plan would be to post the job with some images and get some quotes.
