That really sounds like the best idea, so far. The thing that was bothering me the most about this GAP, is that it IS so LOW DOWN from the back edge of the tub. Like it could get really mucky down there, over time. I like the raise it up idea a lot. I guess we'll have to raise up the edges all around, maybe about an inch & a half. It'll all just be UP a little higher, around the edges, right?? Thanks for your advice. I really need advice!!! Elizabeth
