This Toilet-in-a-Box kit includes tank, bowl, toilet seat, wax ring, and all hardware needed for installation. A tall, narrow tank design with 3” flush valve and an extra-large dual-fed siphon jet power water into and around the bowl for a thoroughly cleansing wash. Large front rim holes send a powerful surge of water that help keep the bowl streak-free. A proprietary, large, fully glazed trapway provides virtually clog-free performance. A corrosion-resistant rigid flapper ensures consistent operation while the reliable Fluidmaster® 400A fill valve quickly and quietly refills the tank. Viper’s elegantly tapered tank with tight-fitting lid and slightly flared bowl make this exceptional toilet a perfect addition to any bathroom or powder room. To save time on installation, extra-tall bolt caps eliminate the need for on-site bolt cutting. Plus, Gerber’s exclusive multipoint mounting system and non-corrosive brass tank-to-bowl bolts provide ease of installation and lasting stability, making it ideal for both new installations and replacement applications. With Gerber’s industry-leading, 15-year warranty on parts and components and a limited lifetime warranty on vitreous china, you’ll get Set-It-and-Forget-it™ assurance and leave toilet troubles behind with Viper.\u003c\/p\u003e\u003ch4 class=\"fw-normal mb-0\"\u003eComponents\u003c\/h4\u003e\u003cspan class=\"fw-normal mb-0 sub-header\"\u003e(For finish-specific component item numbers, please see the \u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/M69E\/e3nAlL\/original\/2025_Gerber+US_Price+Book_20250501_Final\" target=\"_blank\"\u003eprice book\u003c\/a\u003e.)\u003c\/span\u003e\u003cul\u003e\n\u003cli\u003eBowl Item Number: GVP31552\u003c\/li\u003e\n\u003cli\u003eTank Cover Item Number: GTC38590\u003c\/li\u003e\n\u003cli\u003eTank Item Number: GWS38590\u003c\/li\u003e\n\u003cli\u003eTank Lever Item Number: GA713019WH\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eDownload Data Sheets\u003c\/h4\u003e\u003cp\u003e\u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/D6yq\/larJG\/original\/GTB30552_SS\" class=\"pdp-resource\" target=\"_blank\" rel=\"noreferrer\"\u003eSpec Sheet Tech Doc\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/vblD\/89L3w\/original\/GTB30552_IM\" class=\"pdp-resource\" target=\"_blank\" rel=\"noreferrer\"\u003eInstallation Manual Tech Doc\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003ca href=\"https:\/\/cdn.intelligencebank.com\/us\/share\/g6wE\/lLyv\/RdNWZ\/original\/GTB30552_IPL\" class=\"pdp-resource\" target=\"_blank\" rel=\"noreferrer\"\u003eIllustrated Parts List Tech Doc\u003c\/a\u003e\u003c\/p\u003e","brand":"Gerber","offers":[{"title":"White","offer_id":50681312936233,"sku":"GTB30552","price":276.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0933\/2778\/6281\/files\/unnamed_1f884a1f-c563-45a1-8935-4a4ac94a7093.jpg?v=1753205065","url":"https:\/\/www.gsdesigncenter.com\/products\/viper-1-28-gpf-12-rough-in-toilet-in-a-box-two-piece-round-front-toilet","provider":"GS Design Center LLC","version":"1.0","type":"link"}
