Converting tub to shower only

15 years ago

We are remodeling a recently purchased and nearly gutted foreclosure. The master bathroom is down to the studs, and where there was once a bathtub, we will be installing a shower only. (house has two other tubs). The tub had a right hand drain and we are considering using the Kohler Salient REceptor (floor) that is made out of cast iron. I am wondering if perhaps the better decision would be to have the drain recentered to middle of pan and purchase a receptor with middle drain? The concrete foundation is slab/non tension and the stack is adjacent to the left side wall of shower.

Does the drain need to be retrofitted to 2" from the 1 1/2"? Is a middle drain better than the right hand in the cast iron shower pan ?

Thanks!

For a standard shower, the offset drain location will work fine. The Kohler cast iron pans are excellent quality.

With code revisions, a 2" drain is the standard. Most inspectors require the drian to be upsized with a gut remodel.

If you do have to blow out the slab to upsize the drain, then it really isn't much more work to extend the drain to the center and go with the middle drain pan if you think that will be more pleasing. But performance-wise, either is fine.

Wow. I've never seen or heard of a cast iron shower receptor/floor. Does anyone have pictures of an installed one?

Thanks Mongo! I can see the drain and it is a 2 inch pipe with a reducer to 1 1/2. Plumber will be changing it to two. If the right side will work fine then I think I will leave it at that. I have no preference looks wise, just wanted to make sure it was adequate. Thank you for letting me know the rh will work.

prickly pearcactus, I don't have any pictures of the receptor installed. There is one on Kohlers site (link below). I learned about this on this board and was really pleased with the price too, about $490 from Home Depot for a cast iron huge one is not bad at all.
