UPDATE: We didn't know until we installed – which was a huge pain – the drain hole was not drilled on center and caused LEAKS through the fiberglass at junction of the built in overflow drain. Like others in the feed mentioned, regular pipe fittings won't work for the drain - the threads are not a match. We had to improvise to make it work with the the regular PVC fitting. Installing into mortar was also a huge hassle and difficult to level because the feet were not the same height. We wound up throwing it out and buying a new one. We've ordered so many things for a whole-house renovation from Wayfair with no problems. Sorry to say this was a major fail.

This tub is awesome! It's super deep and sloped perfectly for a soaker tub. It comes with a pop-up drain, super easy to use.
