OATEY 42049 2 in. 2-Part PVC Solvent Weld Shower Drain with Plastic Strainer

That's exactly what the 42049 is built for. It's a two-part PVC drain for preformed shower bases: the receptor base has the body locknut integrated into it, so you're not fighting a loose locknut up under the pan while you set the drain body into the base. Fiber and rubber gaskets seal it to the pan. It is not a drain for a mortar-bed or hot-mop tile shower, which needs a clamping ring style body instead.

Yes. The drain top takes 4-1/4 in. Universal Snap-Tite strainers, and those come in a range of designer finishes. So the plastic strainer that ships with the 42049 is a starting point, not a commitment. For a property manager standardizing the look across units, the drain body stays the same in every bath and only the snap-in strainer changes.

Not directly. The 42049 receptor base is PVC and is made to solvent weld to 2 in. Sch. 40 DWV PVC. PVC cement doesn't bond ABS, and it doesn't bond to cast iron at all. On an ABS system you want the ABS version of the same drain; on cast iron you transition to 2 in. PVC first with a shielded no-hub or a proper transition coupling, then glue the receptor base to that PVC stub.

Two-part means the receptor base and the drain body are separate pieces. The base cements to the 2 in. Sch. 40 DWV riser and carries the locknut; the drain body then draws down into it from above with the fiber and rubber gasket between, clamping the shower base wall. That split is what lets one person set the drain from inside the pan after the base is dropped, instead of needing access underneath to run a locknut.

The 42049 takes the 4-1/4 in. Universal Snap-Tite strainer, which is Oatey's common snap-in size, so strainers you already keep on the truck in that size drop straight in. Measure across the outside edge of the strainer flange, not the openings, when you check a spare.

Order it as Oatey 42049. That's the model and the manufacturer part number both, and it identifies the 2 in. two-part PVC solvent weld shower drain supplied with the plastic strainer. Nothing else to specify, there are no size, finish, or connection options on this one.

Right at 0.708 lb per drain, which matters mostly when a plumbing contractor or MRO buyer is pulling a pallet quantity for a multi-family rough-in. It's a light PVC assembly, so a case of them ships as a small parcel rather than freight.
