Grinder pump in basement

[Christian M.]

Hey, guys. I'm picking up a house with a finished basement. The basement is below the sewer line and only has a shower and a sink, no toilet. There is currently some sort of pump bringing the water from the shower/sink to the sewer line. I want to put in a toilet to make it a "real" bathroom as there is only one toilet in the house (on the main level).

Does anyone have any ballpark idea of how much it would cost to install a toilet and a grinder pump for the waste? I think something like this would do:

Alternatively, do you think it would be worth it to put a toilet in, or is my money better spent elsewhere in the house?

Thanks in advance!!!
