Tub Drain - Factory faux pas

[C Williams]

We special ordered a Maax tub for a new build and after 8 weeks it finally arrived. Today, while prefitting the drain and overflow, I see that the top surface around the drain is not coplaner with the machined surface under the drain. Unfortunately the difference is substantial and there is no way I can compress the rubber washer on the underside enough to seal around the thinner portion of the drain perimeter.

I'm looking for ideas to fix this. My ideas are:

1. Put it back in the box, load it in the truck, drive to the factory and toss it through their front window. As satisfying as that might be it's not going to fix my problem.
   
   
2. My next thought is to get out a grinding disk and make the surfaces coplaner. The thinnest area is only 2.8 mm (7/64") and I'm not certain that it will be enough meat to work with. The thickest portion is 4.2 mm (11/64") so I'd have to grind off about 1.4 mm on the high side only.
   
   
3. I could also mix up some fiberglass, build up the area and machine a new surface once it's cured. Ugh

Option 1 is looking better and better.

Other ideas?

The overflow gasket is tapered. Maybe an option.

ANYTHING you do to it will void the warranty, and if it does NOT work, you will be stuck with it. Return it.

Agreed. Thank you.

Credit where credit is due.

I called Maax in Quebec this morning and explained the problem to their customer service department. They asked me to email them photos along with the serial number. Shortly after I received a call back from them. They told me that they would send out a service technician with in 48 hrs too repair the tub.

Now, I live on a rural Island off the coast of Vancouver Island so I didn't expect them to make the 48 hr service commitment. 20 Minutes later a service technician called me to arrange an appointment. One hour later he was on a boat. I'm delighted to report that as of now the tub has been impeccable repaired and the technician is on his way home.

Stunning! Truly stunning!
