We are in the process of adding a 2nd floor to our house, and the plumber has roughed in the shower drain. On the plans, only one drain was marked by the designer -and two lights were marked above. The drainage slope to the drain was also indicated on the plans. The plumber however has roughed in two drains - right where the lights are supposed to be above the shower. It is a large shower, to be sure - about 4 x 7 feet - but there are no extra body sprays or anything, just a rainhead and hand-held shower.
The plumber is now contending that this was not a misreading of the plans (despite the coincidence that he's located the drains exactly where the lights were supposed to be above) and that he put two drains in the shower in spite of the plans or any discussion because he had to to meet code. I think that code in this case is code for,"we don't want to admit we made a mistake and we don't want to redo it".
So my question (and I do have one) is, has anyone ever heard of larger showers needing two drains, despite the fact that the volume of water is no greater than it would be in a smaller shower, to meet code? I realize the code here in Alberta would be different than other places to an extent but this just seems to defy logic to me. BTW we used the same shower fixture combination in a smaller shower on the main floor a couple of years ago and that shower only has one drain.
