Is there a lift that is small enough to fit in a small bathroom and can support the weight of a 190 pound man?

My in-laws live in a home that was built in the 1950's and there isn't much room in the bathroom. They recently remodeled it to accommodate my FIL's wheelchair but there isn't much room between the toilet and the shower. The shower can accommodate a wheelchair but there is a soffett above the entrance to the shower. Don't have the actual measurements though. Does anyone know what the measurements need to be? I know there is a lift that a metal bar of sorts is put into the ceiling; this is out of the question as far as my MIL thinks, so the lift will have to be on a stand. Also, is it difficult to transfer a very elderly man whose legs do NOT support him from the toilet to the lift or the lift to the toilet?
