We are in the process of converting an existing half-bath to a full size bathroom within an in-law-apartment. We are limited on the amount of space to expand but need enough room to accommodate a handicapped person using a walker. The contractor suggested installing a corner toilet which will allow room to move around with a walker. I've never heard of a corner toilet. Are there any concerns I should have with a corner vs. a standard toilet? The brand considering is an Eljer Titan Triangle 17" toilet. Thanks a bunch!
