I have had a problem with the lock handle getting bumped and unlocked. I have had this happen 6 times since I got it. I LOVE my tub but this problem has done damage to flooring and baseboards and probably sheetrock. I would like to see a replacement handle that is harder to unlock with say a button to push on the handle. I have seen this type of handle before on other things. User's recommendation: This tub is so awesome. I love mine. But the lock handle should be harder to come unlocked.
