Howdy folks, My bathroom currently doesn't have a bath, and I'm currently looking at ripping out the shower cubicle and replacing it with a corner spa. I have a space approximately 1700x1500 to put it in, so no worries there. The only problem is that the center of the shower drain is in the corner of the bathroom, approximately 200mm from each edge. It would be an extremely expensive operation to put in a new drain, as the house sits directly on top of a concrete slab. My only option therefore, is to find a spa that has a drain plug located pretty much on top of the existing drain hole. I've looked at a metric butt-ton of corner spa baths on eBay etc, but can't find one with a drain plug even remotely that close to the corner of the spa housing. It's a long shot I know, but has anyone here seen a spa bath that would have the plug located approximately 280mm (pythagoras' rule) diagonally in from the corner?
