Shower & Floor Drains
Shower & Floor Drains Buyer's Guide — TradieCart
From linear grates and tile insert drains to standard square floor wastes, we stock a full range of shower and floor drainage solutions for residential and commercial projects. Our preferred brands — Demtech and Roberts Designs — are complemented by popular ranges from Lauxes, BAT, Wedi, Hayman, and Akril.
Understanding Drain Types
- Linear Grates — long channel drains (650mm–1850mm+) that require only a single-direction floor fall. Ideal for large-format tiles, walk-in showers, and wet rooms. Available in wedge wire, slotted, and tile insert coverplate styles.
- Tile Insert Drains — the tile sits inside the grate frame for a near-invisible finish. Available as both linear channels and square point drains. Best for seamless, design-focused bathrooms.
- Square Floor Drains — traditional point drains (80mm–130mm) requiring a four-way floor fall. Cost-effective and straightforward to install — the go-to for standard bathrooms and laundries.

Common Questions
Linear grate or square floor drain? — Linear grates need only a single-direction floor fall, making them easier to tile with large-format tiles. Square drains require a four-way fall but are more cost-effective. Choose linear for walk-in showers and modern designs; square for standard bathrooms and laundries.
Taipan or standard Demtech 65mm kit? — Both are WaterMark Certified and include all installation materials. The Taipan has a slotted coverplate designed to be tiled over for a near-invisible finish. The standard kit offers five interchangeable coverplate styles including a reversible tile insert — more versatile if you want to change the look later.
What size waste outlet do I need? — DN50 (50mm) is suitable for secondary drainage points or elevated construction with access to pipework below. DN80 (80mm) is required when the drain is the primary floor waste on slab-on-ground construction.
Which finish should I choose? — Match your drain to your tapware and bathroom hardware. Stainless steel and chrome suit classic designs. Matte black is the most popular modern choice. Brushed gold and antique brass add warmth to premium bathrooms.
Demtech or Roberts for linear grates? — Demtech kits include all plumbing outlets and installation materials in the box, with five coverplate styles per colour. Roberts offers 316 stainless steel construction with Matte Gold as an additional finish option. Both are WaterMarked.
