Bathroom Floor Wastes

For wet room bathrooms, we recommend our 304 stainless steel floor waste with a 50mm water seal and integrated hair catcher. The 50mm water seal provides reliable odor prevention even with regular water exposure. Choose a round design for traditional wet room layouts with radial tiling, or a square design for modern wet rooms with large-format rectangular tiles. For premium wet room designs where visual minimalism is important, our tile-in/invisible floor waste creates a seamless appearance by embedding the surrounding tile into the drain cover.

The standard bathroom floor waste has a body depth of approximately 80-100mm depending on the specific model and size. This is suitable for most floor slab depths in new construction (typically 120-150mm). For renovation projects or buildings with shallow floor constructions, we offer a low-profile variant with reduced body depth of 60mm, which can be installed in floor build-ups as shallow as 80mm total (including tile, adhesive, and substrate). We can provide detailed dimension drawings (DWG/PDF) for integration into your plumbing plans.

Yes, our stainless steel bathroom floor wastes are fully compatible with underfloor heating systems (both electric mat and hydronic systems). The 304 stainless steel construction handles temperature variations from 5°C to 80°C without deformation or performance degradation. During installation, ensure proper thermal expansion gaps (2-3mm) are maintained around the drain frame where it meets the surrounding floor. The stainless steel grate will not become uncomfortably hot to touch, as the metal dissipates heat efficiently across its surface area.

Yes, our tile-in/invisible floor waste is designed for modern bathroom designs where seamless floor aesthetics are desired. The drain features a recessed cover channel (10mm deep, full width) into which the surrounding tile is embedded, creating a nearly invisible appearance where only a thin stainless steel frame (3-4mm visible edge) is visible on the floor surface. The tile must be cut to precise dimensions (we provide a cutting template) and bonded to the cover with appropriate tile adhesive. Available in standard sizes (100x100mm, 150x150mm) with 304 stainless steel construction. The tile-in variant maintains the same 50mm water seal and flow performance as our standard models.

The primary difference is aesthetic — both round and square floor wastes use the same internal trap mechanism and deliver identical flow performance (20-30 L/min) and water seal depth (50mm). Round floor wastes are the traditional choice and work well with small-format or mosaic tiles where radial slope patterns are used. Square floor wastes are more popular in modern bathrooms with large-format rectangular tiles, as they align with the tile grid and create cleaner visual lines. The choice between round and square should be based on your tile layout and design preference — there is no performance difference.

The most common cause of bathroom odors is a dried-out water seal in seldom-used floor drains. When a floor waste is not used for several days or weeks, the water in the trap can evaporate, allowing sewer gases to enter the room. Solutions include: (1) Installing our waterless trap insert into the existing floor waste — this creates a mechanical seal that does not rely on water; (2) Using our mechanical odor trap (EN 1253-7 compliant) which automatically closes when water is not flowing; (3) Periodically running water into the drain to refill the water seal. For guest bathrooms that may go unused for weeks, we recommend the waterless trap insert as the most maintenance-free solution.
