Tub install took way longer than expected - not because it was hard to do, but the manufacturer stripped two of the screws to the access panel. I ended up using a screw extraction set to remove them, which took about an hour. After that it was smooth sailing, quick fill (about 20 minutes) and total time for the tub to heat up was about 24 hours. Looks much nicer than I expected, perfect size for our patio. Very happy with the tub overall.
