We are replacing a 20 year old tub with a new Sovereign from Hot Springs. The plywood platform we have is roughly 1" (max) uneven across the run of 76".
Although I could see that the old tub wasn't level it never really bothered us. Should I be concerned about this gap from the standpoint of the tub? Can shims be used for a gap like this?
Thanks in advance for your helpful comments!
