Check out some of the websites for macerating type toilets,etc, such as the "sani plus,"sanitary for all" , saniflo.com. for more info.
They will accomodate a toilet, basin, shower or tub, and are great for installing into a septic piping layout, especially a basement. the macerating toilet and tank may be slightly on the costly side (approx $800)the ease of piping and no time consuming digging up of floors etc is required. They can be installed anywhere in the home you want . I installed mine in my rural home several years ago for approx $900 and that included the toilet, macerating tank and the piping ,fittings etc . Obviously the fixtures such as the basin, shower, tub are an added cost. Once these fixtures are in place it takes less than a day to complete the hook up.
And besides being easy to install, the toilet and tank look very much the same as any other normal toilet and tank. And no 'permit' was necessary either.
Btw, these tanks are about the same size as your normal toilet tank, they sit on the floor(behind the toilet and can pump waste vertically up to 12 ft, and horizontally up to 100ft. which will take care of the majority of most basement septic layouts.
