I also have a cedar tub but mine has a vinyl liner in it. Probably not what you had in mind but it eliminates all the issues common to cedar tubs. Another nice feature is there is a layer of insulation under the liner which comes in handy in the great white North.
If you're interested these guys will sell you a liner for your tub:
No they won't, I called them to ask. The owner was not helpful at all. They don't sell liners. Basically said unless your buying one of there tubs, don't bother them. I made a fibre glass lining for mine with 2 inch insulation. Works awesome.
