McAlpine ST90CPB-S-70 Shallow Shower Trap – 90mm | 70mm Height | 50mm Seal
The McAlpine ST90CPB-S-70 is a shallow shower trap engineered for low-profile installations where sub-floor clearance is limited. At 70mm overall height with a superior 50mm water seal and 34 litre/min flow rate, it delivers full performance in space-constrained applications — ideal for timber floor constructions, low-profile shower trays, and bathroom renovation projects. The 1½″ BSP solvent weld outlet connects to standard 40mm waste pipework, and the polypropylene body is fully compliant with BS EN 274-1:2002 and BS EN 274-2:2002. ⚠️ Check tray thickness and clearance before ordering. The ST90CPB-S-70 suits tray thickness 5–30mm and requires 70mm clearance beneath the tray. If your tray is 0–23mm thick and you need a Multifit outlet, see the McAlpine ST90CB10-70. If you have less than 70mm clearance, see the McAlpine ST90CPB-S-53 (53mm height).

Both are McAlpine 90mm shallow traps with 70mm height, 50mm water seal, and 34L/min flow rate. The key difference is tray thickness compatibility and outlet type. The ST90CPB-S-70 (this product) suits tray thickness 5–30mm and has a 1½″ solvent weld outlet. The ST90CB10-70 suits tray thickness 0–23mm and has a Multifit outlet compatible with plastic, copper, and lead pipe. Check your tray thickness and pipework type before ordering. What clearance does this trap require beneath the shower tray? The ST90CPB-S-70 has an overall height of 70mm and requires 70mm of clearance beneath the shower tray. Measure the available depth between the underside of your shower tray and the floor before ordering. If you have less than 70mm available, see the McAlpine ST90CPB-S-53 (53mm height). What tray thickness is this trap suitable for? The ST90CPB-S-70 suits shower trays with a thickness of 5–30mm. If your tray is thinner (0–23mm), the ST90CB10-70 may be more appropriate — check the overlap range for your specific tray thickness. What type of outlet connection does this trap use? The outlet is 1½″ BSP solvent weld, connecting to standard 40mm (1½″) solvent weld waste pipe. A 135° bend, BSP coupling nut, and 1½″ universal connector are included to allow flexible pipe routing beneath the tray. What is the water seal depth, and why does it matter? The water seal depth is 50mm. The water seal is the depth of water retained in the trap that prevents sewer gases from entering the bathroom. The minimum required by UK building regulations is 25mm. A 50mm seal provides significantly better odour protection and is less likely to evaporate in infrequently used showers. If clearance is too restricted for this trap, the ST90CPB-S-53 offers a 25mm seal at just 53mm height. Is this trap BS EN 274 compliant? Yes — the McAlpine ST90CPB-S-70 is fully compliant with BS EN 274-1:2002 (requirements) and BS EN 274-2:2002 (test methods), the relevant British and European standard for sanitary waste fittings.
