We've purchased an MTI undermount bathtub. Finding someone reliable to build its frame has been challenging, so it looks like we may be doing it ourselves (we can skill-wise, but just don't want to if we have the choice.)

So has anyone built their own frame for their MTI (or undermount) tub? Any tips besides having a level floor and checking for leaks before we haul it into the house?

Thanks! Much appreciated!
