Our home had a liner-type thingy when we moved in. I LOVE it - mainly because the people before us had the tub removed and replaced with the full-size shower only. I love having that huge shower space. They also added sliding doors which I also love. When it comes time to remodel, I want to keep the shower only and have it tiled for a change. The one thing I do not care about with the fitter is the clear caulking at the seams - hard to keep clean.
