Most of us are familiar with round or square floor drains, but not a linear one. However, most newly renovated homes in Dubai feature this drain. That shift is visible across bathroom renovations throughout Dubai: walk-in showers with no tray, large-format tiles running from floor to wall without interruption, and a single channel running along one edge to handle all the drainage.
But the fact that shower channels are everywhere in new Dubai builds doesn’t mean they’re automatically the right choice for every renovation project. The decision between shower channels and point drains involves tile format, floor fall direction, available drain pipe position, slab depth, and the specific look the bathroom is trying to achieve. Getting that decision wrong, or leaving it until after the screed is poured, is when renovation budgets go over and timelines slip.
What Each System Is
Below is a brief overview of both systems.
Point Drains Square and Round
A point drain sits at the centre or a corner of the shower area. Water falls toward it from all sides, which means the floor screed has to slope in four directions simultaneously, a four-way fall. The drain body connects to the waste pipe directly below.
Square two-piece and three-piece floor drains are the simplest available for showers. They are installed in common areas within a home, including kitchens and bathrooms, and are available in sizes 10x10cm or 15x15cm, made of high-grade AISI 304 stainless steel, with a vertical drainage outlet.
Shower Channels Linear Drains
Linear floor drains are available in both tileable and design-oriented grates and are used primarily in shower areas. A shower channel runs along one wall or across the width of the shower, collecting water along its full length rather than at a single point. The floor screed slopes in one direction, with only a single fall toward the channel, which is significantly simpler to lay than a four-way fall and better suited to large-format tiles.
The Core Decision Factors
Floor Fall Direction and Screed Complexity
This is the most important structural consideration and it needs to be decided before the screed goes down.
A point drain at the centre of a 1200x1200mm shower requires the floor to slope toward that central point from all four edges, four separate fall directions converging at one point.
A shower channel along one wall needs a single-direction fall toward that wall. One slope, consistent across the entire floor. Large format 600x1200mm tiles can be laid parallel to the fall direction with minimal cuts and a clean result.
Drain Pipe Position in the Slab
This is the constraint that often overrides aesthetic preference. The existing drain pipe connection point in the floor slab determines where the drain can go without cutting into the slab, which in most Dubai apartment buildings is not permitted without structural approval.
Wet Room vs Enclosed Shower
For a fully wet-room bathroom with no enclosure, tiles covering the entire floor, and a shower area defined by the drainage zone rather than a physical barrier, shower channels are the standard choice. The single-fall floor geometry works across the entire room; the channel sits flush with the finished tile surface, and there’s no visible tray edge or threshold.
Grate Options: Tileable vs Design Grate
Both point drains and shower channels are available with two grate types, and this choice affects visibility.
- Tileable grates are filled with tile cut to match the floor covering. When done correctly, the drain is almost invisible; only the narrow gap around the tile insert reveals its location. This works best when the tile format allows a clean cut to fit the grate recess without excessive waste or mismatched grout lines.
- Design grates in stainless steel, matt black, or brushed finishes are visible by design. MCH CHUDEJ’s shower channel range includes a matt black frame option in 600mm and 800mm sizes with vertical outlet D50. A design grate in matt black or brushed stainless becomes a visual element of the bathroom rather than something to hide, particularly effective when the grate finish matches the mixer and accessory finishes.
The MCH CHUDEJ Klasik 600mm model features an adjustable horizontal siphon, useful when the pipe connection height needs to accommodate screed depth variations that occur in renovation projects where the existing floor level is being retained.
Material and Corrosion Resistance
Most shower channels in the UAE market are made from AISI 304 or AISI 316 stainless steel. The difference matters in specific applications.
AISI 304 is standard for residential bathroom environments; it resists corrosion from moisture, soap, and cleaning products under normal conditions.
AISI 316 contains molybdenum, which significantly increases resistance to chloride corrosion. For bathrooms in coastal buildings along Dubai Marina, JBR, or Palm Jumeirah where salt-laden air penetrates into buildings, AISI 316 is the better choice for any component that will be permanently wet. BONOMINI’s Canalissima range uses AISI 316 throughout.
Installation Checklist Before Committing
| Factor | Point Drain | Shower Channel |
| Tile format | Best with tiles under 400x400mm | Better with large format tiles |
| Floor fall | Four-way fall required | Single-direction fall |
| Existing pipe position | Must be directly below drain | End or side of channel flexible |
| Slab depth | Standard | Check horizontal outlet option if limited depth |
| Wet room layout | Less suited | Standard choice |
| Visual preference | Concealed or tileable | Tileable or design grate finish |
Final Take
The right drainage system depends on the tile format, the existing pipe position, the floor area, and whether the shower is enclosed or open. Shower channels suit the large-format tile layouts and wet-room configurations that dominate Dubai bathroom renovations today, but the drain pipe position in the slab is the constraint that must be confirmed before anything else is decided.

FAQs
Why are shower channels more common in new Dubai bathroom renovations?
Because most new builds use large-format tiles that suit a single-direction floor fall far better than the four-way fall required by a central-point drain. Shower channels also work cleanly across full wet room layouts without a visible tray or threshold.
What sizes are available in the TAPS & MORE shower channel range?
T&M DESIGN Publik channels come in 300mm, 600mm, and 900mm. BONOMINI Canalissima channels are available in 600mm, 800mm, and 1000mm. MCH CHUDEJ Klasik and Slim Line are available in 600mm and 800mm.
What is the difference between AISI 304 and AISI 316 stainless steel for shower drains?
AISI 316 contains molybdenum, which resists chloride corrosion relevant for bathrooms in coastal Dubai buildings where salt-laden air reaches internal fittings. AISI 304 is adequate for standard inland residential environments.
Can shower channels be installed where the drain pipe isn’t centred on the wall?
Yes. T&M DESIGN’s Publik channels are reversible; the outlet can be positioned at either end of the channel body. BONOMINI Canalissima offers horizontal outlet options for side-pipe connections when slab depth is limited.
