Full-Bore 2" × 2" 50mm In & Out High Flow Universal Connection For Linear Drain Trays Trade Specification
The Taurus 2-2 Universal Linear Waste Trap is a full-bore, high-flow waste trap designed for use with linear drain wet room tray formers. The "2-2" designation refers to the trap's full 2" (50mm) connection at both the inlet and outlet — meaning the entire flow path from the drain channel through to the waste pipework runs at full 50mm bore with no internal restriction. This is the professional trade specification trap for wet room installations where 50mm waste pipework is run throughout, delivering maximum drainage capacity with no reducers in the system. The universal 2" outlet connection is compatible with standard UK 50mm solvent weld and push-fit waste pipe, making it straightforward to integrate into any standard domestic or commercial drainage layout.
What Does "2-2 Universal" Mean?
In UK plumbing trade terminology, waste trap sizing is expressed as inlet diameter × outlet diameter. A "2-2" trap has a 2" (50mm) connection at both the inlet and outlet — meaning the bore is consistent and unrestricted throughout the trap body. This is the full-bore specification.
The standard version of the Taurus/Abacus Elements linear waste trap includes a 2"→1½" reducer, allowing connection to the more common 40mm (1½") waste pipework found in most domestic bathrooms. The 2-2 Universal version omits this reducer entirely — both connections are 2" (50mm). This is the preferred specification for:
- Installations where 50mm waste pipework is run throughout the floor construction from the outset
- Larger wet rooms or commercial/contract applications where maximum drainage capacity is required
- Installations where a Building Control officer or specification has required 50mm waste runs for a wet room drain
- Situations where the waste run length is longer than typical, where maintaining full bore helps preserve adequate self-cleansing velocity in the pipe
The "Universal" part of the name refers to the outlet connection type — a 2" universal fitting that accepts standard UK 50mm solvent weld pipe, push-fit pipe, and compression fittings, without requiring any specific pipe brand or jointing method.
Key Features
🔵 Full 2" × 2" Bore ThroughoutBoth inlet and outlet are unrestricted 2" (50mm) connections. No reducers, no bottlenecks. The entire flow path from linear drain channel to waste pipe runs at full 50mm bore for maximum drainage capacity.
💧 High-Flow Linear Drain RatedDesigned for use with linear drain wet room tray formers, which concentrate the full flow of a shower into a single channel waste point. The full-bore 2" connection ensures the trap is never the limiting factor in drainage performance.
🔧 Universal 50mm Outlet ConnectionThe 2" universal outlet is compatible with standard UK 50mm solvent weld waste pipe, push-fit, and compression fittings — works with all standard domestic and commercial waste plumbing systems without special adaptors.
📐 For Taurus Linear Tray FormersDesigned as the waste trap component for Taurus XPS wet room tray formers with linear (channel) drains. Connects to the underside of the linear drain body and routes waste to the horizontal floor drainage run.
↔️ Horizontal OutletSide-exit horizontal outlet connects directly into the floor waste run. Suitable for both timber joist and concrete screeded floor construction. The horizontal configuration eliminates the need for vertical sub-floor clearance directly beneath the drain.
🛡️ Water Seal — Odour PreventionIncorporates an integral water seal to prevent drain odours and foul air entering the wet room via the drain. Maintains the water seal under normal intermittent shower use conditions.
🏗️ Trade / Professional SpecificationThe 2-2 full-bore configuration is the trade specification for installations where 50mm waste runs are required or specified. Eliminates any flow restriction at the trap body, which is the most common point of undersizing in standard domestic wet room drainage.
🧹 Accessible for MaintenanceTrap body designed for access and cleaning as part of the linear drain assembly. The drain channel cover plate removes for routine hair and debris clearance without requiring access to the sub-floor waste connections.
2-2 vs Standard Linear Waste Trap — Which Do I Need?
| Feature | Taurus 2-2 Universal (This Product) | Standard Linear Waste Trap |
|---|---|---|
| Inlet connection | 2" (50mm) full bore | 2" (50mm) full bore |
| Outlet connection | 2" (50mm) full bore — no reducer | 2" inlet, includes 2"→1½" reducer for 40mm pipe |
| For 50mm waste pipework | ✓ Direct connection, no adaptor needed | ✗ Reducer must be removed or bypassed |
| For 40mm waste pipework | ✗ Requires separate 2"→1½" reducer | ✓ Reducer included in kit |
| Maximum flow capacity | Higher — unrestricted throughout | Standard — limited by reducer where fitted |
| Typical application | Trade/contract, longer waste runs, 50mm spec | Standard domestic, 40mm waste pipework |
ℹ️ Which Pipe Size Do I Have?
The most common domestic waste pipe size in UK bathrooms is 40mm (1½"). If your floor construction uses 40mm waste runs, the standard linear waste trap with its included 2"→1½" reducer is the correct choice. The 2-2 Universal trap is for installations specifically using 50mm waste pipe throughout — typically where Building Control has required a larger bore, or where the installation is a commercial or larger-scale project. If you are unsure, check the outside diameter of your waste pipe: 40mm pipe measures approximately 40mm OD; 50mm pipe measures approximately 50mm OD.
⚠️ For Linear Drain Tray Formers Only
This trap is designed specifically for use with linear drain (channel drain) wet room tray formers — where the drain runs along one end or side of the tray rather than a central point drain. It is not compatible with square point-drain tray formers, which use a different waste body geometry. Confirm your tray former type before ordering.
Installation Overview
The 2-2 Universal linear waste trap installs as part of the tray former drainage assembly during floor preparation, before the tray former is bedded into position. The trap body connects to the underside of the linear drain channel in the tray former and the horizontal outlet connects directly to the 50mm waste pipe run in the floor void. On timber joist floors, the outlet typically routes between joists to a stack; on concrete floors with screed, the waste pipe is laid within the screed bed before the tray is positioned.
The trap must be set at the correct height relative to the finished tray surface during installation — the linear drain channel height is determined by the tile thickness that will be applied over the tray surface. Once the tray former is bedded and the installation is tiled, the trap position is fixed and cannot be adjusted. Always follow the tray former manufacturer's installation guidance for setting the waste/trap height before bedding the tray.
🔧 Key Installation Points
Set trap height before bedding tray — not adjustable afterwards. Ensure 50mm waste run is in place before positioning tray former. Maintain minimum 20mm/m fall on all horizontal waste runs. Use solvent weld or push-fit joints as appropriate to your pipe specification. The perimeter joint between the tray former and surrounding floor tiles must always be finished with silicone — never grout this joint as it is a movement joint.

Frequently Asked Questions
Can I use this trap with 40mm waste pipe by adding a reducer?
Yes — a separate 2"→1½" (50mm→40mm) reducer can be fitted to the outlet of this trap to connect to 40mm waste pipework if needed. However, if your installation uses 40mm pipework throughout, the standard linear waste trap (which includes the reducer) would be the more straightforward choice and avoids an additional fitting in the waste run.
Does the cover plate/grate come with this trap?
The linear drain cover plate is a separate purchase. Taurus offer a range of cover options for the linear drain channel — including stainless steel brushed, chrome, and tileable versions — to suit different finished floor aesthetics. Select the cover plate to match your wet room design when ordering.
Is this trap compatible with all Taurus linear tray former sizes?
This trap is compatible with the Taurus linear drain tray former range. Confirm compatibility with your specific tray former model before ordering, as different tray formers may use different drain channel lengths (typically 300mm or 600mm) and the trap body must match the drain channel specification of your tray.
Can this trap be installed in a concrete floor without a screed?
Yes. On concrete subfloors, the waste pipe is typically laid in a channel cut into the concrete or within the screed bed. The trap body sits within the floor construction at the correct height relative to the tray former surface, and the horizontal outlet connects to the waste run. Ensure the concrete or screed provides adequate support for the trap body and that the outlet pipe has sufficient fall (minimum 20mm per metre) to the drainage stack.
Do I need a separate installation kit with this trap?
Yes. The linear waste trap is the drainage component of the wet room tray former system. A separate Taurus tray former installation kit is required for the full installation, which includes Fix-KST adhesive, Pro-Seal waterproofing compound, waterproof tape, internal corner pieces, wood floor primer (for timber substrates), and associated fixings. The tray former installation kit and linear cover plate are sold separately.
What is the difference between a linear drain and a point drain for a wet room?
A point drain (square waste) collects water from a central point in the tray, requiring the floor to fall towards the centre from all four sides. A linear drain (channel drain) runs along one end or side of the tray, collecting water along its full length — the floor only needs to fall in one direction towards the drain channel. Linear drains are generally considered easier to tile over (especially with large-format tiles), give a more contemporary look, and make it simpler to achieve a fall towards the drain with standard floor tiling methods.
⚠️ Important Notes: This trap is for linear drain tray formers only — not compatible with square point-drain trays. Both inlet and outlet connections are 2" (50mm); a separate reducer is needed to connect to 40mm (1½") waste pipework. Trap height must be set correctly before bedding the tray former — it cannot be adjusted after installation. The linear drain cover plate, tray former installation kit, tray former, and waste pipework are all sold separately. Always maintain a silicone movement joint at the perimeter of the tray former — do not grout.
