10 Inch Rough-In Toilets

A 10 inch rough-in toilet has its floor outlet centered 250 mm (10 in) from the finished wall, a setting often used in compact bathrooms and in older buildings where the drain sits closer to the wall than the common 12 in. This collection holds 78 ceramic toilets that list a 10 in S-trap: 63 one-piece, 14 two-piece and 1 smart toilet. Of these, 77 also list a 180 mm P-trap rear outlet, and many add 12, 8, 16 or 6 in settings. Washdown is listed on 41 models, swirl on 22, rimless on 13 and siphonic on 11. Body lengths run from 635 to 750 mm and heights from 465 to 860 mm. White is listed on 77 models. The range suits renovation, apartment and hotel projects that need to fit an existing 10 in drain.

    Drain at 250 mm

    10 inch rough in toilet range at a glance

    Every 10 inch rough in toilet on this page lists an S-trap floor outlet at 250 mm from the finished wall. What changes from model to model is the body build, the flush path, the second outlet option and the finish, and those four choices decide which lines go on a purchase order.

    Site check

    Confirm the 10 inch rough in toilet setting before you quote

    The rough-in setting is fixed per model, so it is worth confirming before a quote goes out. Check these points on one typical unit per floor plan.

    1. Measure from finished wall

      Run the tape from the finished wall surface, not from baseboard or tile trim, to the center of the drain or the closet bolts. A reading of about 250 mm matches the 10 in setting on every model here; a reading near 200 mm points to the models that also list a 200 mm (8 in) S-trap.

    2. Decide floor or wall outlet

      If the waste pipe leaves through the wall, you need the P-trap connection. 77 of the 78 models also list a 180 mm P-trap rear outlet, so name the outlet on each order line.

    3. Check older drawings against the slab

      Where the plan set and the site may differ, measure a sample of units before releasing the order and note any that read a different setting.

    4. Match body width to the bay

      Widths in this group run from 340 to 430 mm. Read the outline drawing on each product page and put the width you need on the RFQ.

    Seven bodies, real specs

    How representative 10 in models compare

    These seven models cover the main splits in the range: one-piece versus two-piece, single versus dual rough-in, and white versus color bodies. Sizes are length × width × height.

    TC-7309 and TC-7115 share the same 640 × 350 × 800 mm outline in two-piece and one-piece form, which makes them a natural pair when one project wants both builds at a matching size.

    FAQs

    Which 10 inch rough-in toilets are in this collection?

    The collection holds 78 toilets that list a 10 in S-trap rough-in: 63 one-piece, 14 two-piece and 1 smart toilet. Body lengths run from 635 to 750 mm, widths from 340 to 430 mm and heights from 465 to 860 mm. Use the type filter to split one-piece from two-piece bodies, or browse the full one-piece toilet range.

    How is a 10 inch rough-in measured?

    Rough-in is measured from the finished wall, not the baseboard, to the center of the floor drain. A 10 in rough-in means about 250 mm. A toilet with a 12 in rough-in will not sit flush against the wall over a 10 in drain, so measure on site first, then confirm the setting against the drawing on each product page.

    Do these toilets list other outlet options?

    Yes, many do. 77 of the 78 models also list a 180 mm P-trap rear outlet for drains that run through the wall, and selected models add 12 in (26 models), 8 in (10), 16 in (10) or 6 in (1) S-trap settings. Each product page shows the settings listed for that model, and the rear outlet toilet collection groups the P-trap range.

    What is the MOQ and lead time for 10 inch rough-in toilets?

    MOQ, samples and lead time are quoted per model, because they depend on the model mix, finish, carton marking and destination. Send the 10 inch rough-in toilet models, quantities and destination port in one inquiry, and the quotation states each figure line by line. Written replies are issued within 12 business hours, so a project schedule can be checked before the order is placed.

    Can 10 inch rough-in toilets carry our own brand?

    Private-label supply runs through the SANIKB OEM and ODM program: brand marking on the product, carton and inserts, with documents prepared model by model. Certification marks are listed per model (some models print CE or cUPC), so name the target market and the marks it requires, and the quotation lists which models fit. Mixed containers can carry one-piece and two-piece models together.

    How should a distributor choose among the 10 inch models?

    Start with the body: one-piece models give a single seamless form, while two-piece models pair a separate tank and bowl. Next, choose a flushing style, washdown, swirl, rimless or siphonic, where listed. Then compare body length, which runs from 635 to 750 mm, against the room depth, since a 10 in rough-in often goes with a tighter bathroom.
