      FAQs

      What comes in the SP1018 21 shower valve trim kit?

      SP1018 21 is a shower valve trim kit made of two parts: a rectangular matte black wall plate carrying one flat lever, and a round rough-in body that installs inside the wall. The kit pairs that plate with its own rough-in body, so the visible trim and the concealed body are ordered as one model. Confirm rough-in body dimensions against the model spec sheet before ordering, and list any non-standard rough-in configuration in the RFQ.

      Why choose a valve-only trim with a single lever?

      SP1018 21 is specified as valve only, so the single flat lever is the one control on the plate and no diverter knob sits on the rectangular face. When a job does need a diverter, our matching SP1018 22 diverter trim belongs to the same Flat Blade series, and both models can be quoted side by side on one RFQ with finish and quantity settled at quote stage.

      Which SKU should a purchase order quote for the black finish?

      Purchase orders for SP1018 21 should quote SKU SP1018 21 31 2, which identifies the Matte Black variant and is the only finish offered for this model. Stainless steel is the stated material for the kit. Quoting the complete SKU on submittals and RFQs ties each line to this exact variant, which matters when several Flat Blade series items from set 105 are combined on one purchase order.

      Is the SP1018 21 trim kit cUPC listed?

      Yes, SP1018 21 is cUPC listed alongside its stated stainless steel material, matte black finish, wall-mounted trim with in-wall valve, and 100 pcs MOQ. Before the trim goes into a submittal, ask our sales team for the current listing number and certificate validity so the documentation matches your destination market. Importers should also name the destination country and port, and we confirm in writing which documents can travel with the goods before production is scheduled.

      How many pieces make a minimum order for SP1018 21?

      Our minimum order for SP1018 21 is 100 pcs. Send the target quantity, port of discharge, preferred Incoterm and any rough-in notes for walls that already hold a valve, and a written reply with pricing and lead time follows within 12 business hours. Distributors needing private label boxes can route the order through our OEM and ODM service.
