When choosing a floor drain, you need to consider deodorization, drainage, materials and usage scenarios. Give priority to all-copper or stainless steel materials, and match the floor drain type according to the functional area.
Core principles and recommendations
Deodorization and drainage functions
Deodorization: Give priority to floor drains that combine physical deodorization (such as magnetic attraction, gravity closure) with deep water seals. Water-sealed floor drains (deep water seals) isolate odors through water traps, but the water must be kept moist; self-sealing floor drains (T-type, magnetic levitation, etc.) use mechanical structure sealing and are suitable for dry areas or wet areas with frequent drainage.
Discharge volume: For shower areas, you need to choose deep water seals or side-opening floor drains with large discharge volume; washing machine drainage is recommended to use a dedicated self-sealing floor drain to avoid overflow.
Material selection
All-copper material: Strong corrosion resistance and long life, suitable for users with sufficient budget.
Stainless steel material: High cost performance, but attention should be paid to surface treatment technology (such as 304 stainless steel).
Avoid zinc alloy: Easy to rust and age, short service life.
Differentiation by function
Shower area: If there is no displacement of the floor drain, a deep water sealed floor drain (such as the six-proof patented model) is recommended; if the floor drain is displaced or a long strip is installed, a side-opening or magnetic suspension self-sealing floor drain should be selected.
Dry area (such as balcony, kitchen): T-shaped or magnetic suspension floor drain is recommended, which has a more stable deodorizing effect.
Washing machine: Special gravity flap or side-opening floor drain to avoid backflow.
Brand and model recommendation
SubmarineSubmarine: Large displacement, strong deodorizing performance, and leading market share (reference model: shower area special series).
WrigleyWrigley: High cost performance, T-shaped spring seal design is suitable for ordinary families.
Old coppersmithOld coppersmith: All-copper material ultra-thin design, suitable for a variety of decoration styles.
