The Hansgrohe FLOWSTAR series delivers modern bathroom drainage with a focus on installer-friendly design and long-term reliability. This line centers on decorative siphons that hide behind sinks while providing steady water flow and odor-free performance. Every unit is engineered to simplify rough-in and finish-stage work, giving you a clean, leak-free result without extra fittings or complex adjustments.

Easy Installation and Reliable Drainage

These siphons are built for fast setup on standard bathroom basins. The pre-assembled components and standardized threading cut down on-site time. The internal trap design maintains a consistent water seal, which blocks sewer gases and reduces the chance of clogs. Each model is pressure-tested to handle typical bathroom drainage loads, so you can install with confidence and avoid callbacks.

Flowstar S Finish Options

The Flowstar S decorative siphon collection offers a wide range of finishes to match any fixture lineup. Choose from brushed black, brushed gold, matte black, polished bronze, white, or red gold polished. All finishes are applied to corrosion-resistant materials that resist fingerprints, water spots, and daily wear. Matching the siphon to your faucet or drain cover keeps the installation looking sharp and professional.

Standard Compatibility and Low Maintenance

These units fit standard 1.25 and 1.5 inch sink drains without adapters. The smooth interior walls prevent mineral buildup and make routine cleaning quick and easy. If service is ever needed, the accessible design allows fast disassembly without damaging nearby tiles or cabinetry. Stocking these siphons means fewer delays, simpler inventory, and faster project turnover.

Built for Professional Installers

Hansgrohe combines precision engineering with practical installer needs in the FLOWSTAR series. From consistent tolerances to durable finish coatings, every detail is designed to save time on site and deliver a clean, reliable result. Upgrade your bathroom drainage setup with a siphon that works as hard as you do and keeps your reputation intact.
