Wall-mounted toilets depend on a hidden but critical component: the in-wall carrier system. At Dupont Kitchen & Bath Fixtures, we carry premium carriers from brands like Geberit, OLI, and TOTO in both 2×4 and 2×6 mounting depths. Our systems support clean, space-saving wall-hung toilets while delivering durability and performance. dupontplumbing.com
2×4 Depth Carriers for thinner walls or renovations — ideal when wall thickness is limited.
2×6 Depth Carriers for standard construction walls — allows more flexibility and plumbing clearance.
We offer carriers rated for Water Smart performance (0.9–1.28 GPF), and standard 1.6 GPF models available upon request. dupontplumbing.com
An in-wall carrier is the structural backbone of a wall-mounted toilet. Its roles include:
Supporting the toilet weight
Housing the concealed tank and flushing mechanism
Keeping plumbing & supply lines stable
Allowing a flush plate interface with the wall
Choose a carrier based on wall construction and the specific brand of toilet you’re installing.

Wall Preparation: Ensure proper stud spacing and reinforcement behind drywall.
Flush Plate Positioning: Leave access for servicing inside — many designs allow you to open via the flush plate.
Supply & Drain Alignment: Plan plumbing before drywall is installed to match carrier inlets/outlets.
Electrical Considerations: If installing a smart toilet with in-wall wiring, allocate conduit or box access behind the carrier.
