Stainless Steel Circle Drains: Rounded Floor Drain in 1.7 mm Sheet

Round drains are the workhorse outlet of kitchens, laundries, plant rooms and back-of-house spaces, where the priority is moving water away reliably rather than hiding the drain. Jawdah's round model is built for that role, with the thickest sheet in its stainless drain range and larger outlet holes than its smallest square and rectangle models.

Below you will find the exact Jawdah table for the rounded drain, guidance on choosing between the two sizes, and the installation and cleaning points that matter for heavier-duty floors. The model belongs to Jawdah's stainless steel floor drain range, made from deep-drawing stainless steel 304 and warranted against corrosion for 25 years.

A round floor drain has a circular grate over a body that collects water from the surrounding floor and sends it to the outlet. Unlike a concealed drain, the grate is visible and takes in water across its whole surface, which makes it tolerant of high flow, food particles and debris.

Jawdah lists this model as the Rounded Stainless Steel Floor Drain with a Standard design. The name Standard indicates a conventional visible grate rather than the hidden or edged cover styles found on Jawdah's square and rectangle drains.

Jawdah's square and rectangle hidden drains use 1 mm sheet, while the rounded drain steps up to 1.7 mm. Thicker sheet makes the body and grate stiffer, so they are less prone to denting from dropped utensils, trolleys and boots, and hold their shape better when the floor is cleaned with brushes and squeegees.

The body is part of a range produced by deep drawing, in which the stainless sheet is pressed into shape in one piece rather than welded. For a drain that sees grease, food waste and frequent washing, a one-piece body without internal seams is easier to keep clean.

The 15 × 15 drain has a 3” hole and suits a single kitchen zone, a laundry or a plant room where water arrives from equipment discharge or floor washing. The 20 × 20 drain steps up to a 3.5” hole and a larger nominal size, which helps where several sinks, dishwashers or hoses discharge onto the same floor area, or where debris load is high.

Both hole sizes are larger than the 1.5” and 2” holes used on the rectangle drains, which is one reason round drains are preferred in service spaces. Confirm the final size with the drainage design, including the branch pipe that receives the outlet.

Remove the grate daily or weekly depending on use, empty any collected debris, and wash the body with hot water and detergent to cut grease. Rinse well and refit the grate.

Do not pour hot oil or fat into the drain, and avoid scouring with steel wool. Check the trap, where fitted, and keep it filled with water.

The round model is aimed at rooms where flow and robustness come first. Typical locations include the following.

The hole size is the outlet opening of the drain; match it to the pipe or fitting specified by the drainage engineer. In kitchens, a drain is often connected to a grease management system downstream, so coordinate the route with the MEP design.

Jawdah notes that some drains can be fitted with a trap that helps reduce odours and insects, depending on use. In kitchens and rarely used plant rooms this option is worth asking for, because a dry outlet can let odours and insects into the room.

Set the drain on its pipe at the correct level, then support it firmly so the heavier body does not shift during screeding. Form the falls so water from equipment discharge points reaches the grate directly, and bed the floor finish tightly against the drain rim to avoid hollow spots that crack under trolleys.

In kitchens with resin or quarry-tile floors, coordinate the finish thickness so the grate sits just below the floor surface.

Watch for these common errors when round drains go into service areas.

These are the values given in Jawdah's Rounded Stainless Steel Floor Drain table, together with the stainless range statement.

The table follows the Jawdah data exactly. The dimension is printed as width by length without a unit, even for this round model, so it is presented as the nominal size as listed; the grate diameter and body size should be read from the Technical Data Sheet.

Kitchens and food areas expose drains to fats, salt, acidic food residues and frequent detergent use. Grade 304 stainless, the material of Jawdah's drain range, handles these conditions in normal use, provided residues are rinsed off rather than left to sit.

Where cleaning involves strong chlorine solutions or descalers, rinse the drain with clean water afterwards. A project that expects unusually aggressive effluent should state its requirement in the enquiry so Jawdah can advise.

Compared with the Stainless Steel Square Drains, the round model trades the concealed look for a thicker 1.7 mm sheet and an open Standard grate that is easier to inspect and clean. The square range offers a 4” hole at 20 × 20, while the round range tops out at 3.5”.

Compared with the rectangle drains on the Stainless Steel Linear Drains page, the round drain gives larger holes at a single point, while the rectangle model spreads the inlet along a line for showers and thresholds.
