The mechanics behind dual-flush actuation are straightforward yet effective. When you press the Geberit Sigma 01, you’re controlling two distinct flush options: a full flush at 1.6 gallons (6 liters) for solid waste, and a partial flush at 0.8 gallons (3 liters) for liquid waste. This simple choice transforms how households manage water throughout the year.
The difference in consumption adds up quickly. Consider that the average person flushes a toilet 6-8 times daily. If even half of those flushes use the partial option instead of the full cycle, you’re looking at significant annual savings. A household of four using dual-flush consistently can reduce toilet water consumption by 25-30% compared to traditional single-flush systems—that’s roughly 13,000 gallons of water per year.
Environmental and Financial Impact
Beyond personal water savings, the environmental benefits extend to reduced strain on municipal water treatment systems and lower carbon emissions from decreased water processing and heating. Your utility bills reflect these savings immediately. Over a 10-year period, dual-flush systems typically save between $800 and $1,200 per household in water costs alone, depending on your region’s water rates.
The hydraulic assistance built into the Sigma 01 ensures that both flush options deliver consistent, reliable performance every time. This isn’t a gimmick—it’s engineered efficiency. The light-touch activation mechanism reduces physical strain on the internal components, which extends the product’s lifespan and minimizes the wear that leads to premature replacement.

Design Finishes: Matching Your Bathroom Aesthetic
Alpine White: The Neutral Foundation
The Alpine white finish (model 115.770.11.5) serves as the foundation for minimalist bathrooms and contemporary spaces. This clean, understated option blends seamlessly with white porcelain fixtures and works particularly well in smaller bathrooms where visual simplicity enhances the sense of space. The finish maintains its appearance with basic cleaning and resists fingerprints better than glossy alternatives.
Polished Chrome: Contemporary Shine
Polished chrome (115.770.21.5) introduces reflective appeal and visual interest. The metallic sheen complements chrome faucets, towel racks, and shower fixtures, creating a cohesive bathroom ecosystem. This finish works best in well-lit bathrooms where the reflection enhances brightness and creates a modern, upscale appearance.
Jet Black Glossy: Bold Statements
The jet black glossy finish makes a dramatic declaration in contemporary and industrial-style bathrooms. This option pairs beautifully with matte black fixtures and dark tile accents, creating visual contrast and sophistication. The glossy surface requires regular cleaning to maintain its striking appearance and prevent water spots from becoming visible.
Matte Chrome: Understated Elegance
Matte chrome offers the warmth of metallic appeal without the high-gloss reflection. This finish provides a refined, understated elegance that works across traditional and modern bathrooms alike. It’s particularly effective in bathrooms with varied lighting, as it won’t create unwanted glare.
Brass Galvanized: Premium Luxury
The brass galvanized finish (115.770.DT.5) represents the premium option for transitional and luxury bathroom designs. This warm, sophisticated tone complements brass fixtures, warm wood tones, and neutral earth-toned palettes. It’s an investment that communicates quality and intentionality in your design choices.
Selecting the Right Finish
Your choice depends on three factors: existing fixture finishes, overall bathroom style, and lighting conditions. Walk your bathroom in different times of day to understand how natural and artificial light interact with potential finishes. Coordinate your Sigma 01 finish with your faucet, towel bars, and other hardware to create visual harmony rather than a disjointed appearance.
Technical Specifications & Dimensions
Physical Measurements
The Sigma 01 actuator plate maintains compact dimensions: width ranges from 9.7 to 11.8 inches, height from 6.5 to 6.8 inches, and depth from 1 to 1.9 inches. These measurements ensure the plate fits modern wall-hung toilet configurations without protruding excessively or appearing disproportionate to the fixture.
Construction and Components
High-quality molded plastic construction provides durability while keeping weight minimal for easier installation. The included components—mounting frame, actuator rods, and distance bolts—are engineered to work as an integrated system. This unified approach eliminates compatibility guesswork and ensures proper alignment with your concealed tank.
Compliance and Compatibility
The Sigma 01 meets ADA compliance requirements in certain variations, ensuring accessibility for users with different physical capabilities. It’s designed specifically for front actuation of Geberit concealed tanks, meaning it won’t work with other manufacturers’ systems. This specificity guarantees optimized performance but requires verification before purchase.
Installation Essentials for DIYers & Professionals
Pre-Installation Preparation
Before opening the package, verify that your existing concealed cistern is a Geberit model compatible with the Sigma 01 series. Check your tank documentation or contact Geberit directly if uncertain. Gather necessary tools: a screwdriver set, adjustable wrench, level, and a measuring tape. If your bathroom has limited accessibility to wall cavities, professional installation may be worthwhile despite the additional cost.
Mounting Frame Attachment
Begin by positioning the mounting frame against your wall, using the level to ensure perfect alignment. Mark the bolt holes precisely, then drill pilot holes to prevent wall damage. Secure the mounting frame with the provided distance bolts, ensuring each fastener is snug but not over-tightened, which can crack the plastic components.
Actuator Rod Alignment
The actuator rods must align perfectly with the mechanisms inside your concealed tank. This is where precision matters most. Even slight misalignment causes sluggish flush response or incomplete activation. Follow Geberit’s alignment guides exactly, and don’t force components into position—they should fit with smooth, gentle pressure.
Common Installation Mistakes
The most frequent error involves over-tightening bolts, which stresses plastic connection points. Another common issue is failing to test flush performance after installation before sealing wall cavities. Always test both the full and partial flush cycles, then make minor adjustments if needed before finishing your wall.
Professional vs. DIY Decision
If you’re comfortable with basic plumbing tasks and have good access to your concealed tank area, installation is manageable. However, if your bathroom has tight wall cavities, existing plumbing complications, or you’re uncertain about tank compatibility, professional installation ensures everything works perfectly and protects your warranty.
Pricing Breakdown: Understanding the Cost Variations
Finish-Specific Pricing
Alpine white (115.770.11.5) ranges from $129.15 to $144.99, making it the budget-conscious choice without sacrificing quality. Polished chrome costs approximately $177.45, representing a moderate premium for metallic appeal. Brass galvanized, at around $375.90, commands a significant investment but delivers unmatched aesthetic impact for luxury renovations.
What Drives Price Differences
Material composition influences cost—chrome plating and brass galvanizing require specialized manufacturing processes. Finish availability affects pricing; premium finishes with lower production volumes naturally cost more. Market demand also plays a role; popular finishes like polished chrome may have competitive pricing from multiple retailers, while specialty finishes show less price variation.
Finding Competitive Pricing
Compare prices across authorized Geberit retailers and sanitary product platforms like skybad.de. Larger renovation projects sometimes qualify for bulk discounts or contractor pricing. Check warranty coverage and after-sales support when comparing retailers; the cheapest option doesn’t always provide the best overall value if service is compromised.
Long-Term Value Proposition
Evaluate cost against longevity. A $129 Alpine white plate lasting 15+ years costs roughly $8.60 annually. Add in water savings of $80-120 yearly, and your genuine cost of ownership becomes negative. The premium finishes deliver similar performance advantages while offering superior aesthetic longevity—you won’t grow tired of a carefully chosen brass galvanized finish the way you might a dated polished chrome selection.
Real-World Performance: What Users Actually Experience
Comfort and Satisfaction
The light-touch activation mechanism consistently receives praise from homeowners. Users report significantly less finger fatigue compared to traditional push-button or lever mechanisms, particularly valuable in households with elderly members or children. The tactile feedback feels responsive without requiring forceful pressure.
Durability Across Years
Contractors who’ve installed dozens of Sigma 01 plates report minimal failure rates over extended periods. The hydraulic assistance protects internal mechanisms from the wear that typically degrades plastic components.

Dual-Flush Reliability
Both flush options consistently deliver their intended water volumes. Users don’t experience the “weak partial flush” problem that plagues poorly designed dual-flush systems. The engineering ensures each cycle completes fully, whether you select the full or partial option.
Maintenance Realities
Cleaning the plate requires only basic wiping with a damp cloth and mild detergent. Fingerprints show more prominently on polished chrome and jet black finishes compared to matte options. Mineral deposits from hard water occasionally require vinegar treatment, but this maintenance is minimal compared to traditional external flush handles.
Plastic vs. Premium Perception
Some buyers initially worry that plastic construction indicates inferior quality. Real-world experience contradicts this assumption. The molded plastic performs identically to metal alternatives while offering advantages: lighter weight, easier installation, and elimination of corrosion concerns. Users who overcome the perception bias consistently report satisfaction.
