Why Choose the McAlpine ST90CPB-S-70?
Ideal for installations where space beneath the shower tray is limited, this shallow trap doesn't compromise on performance. The generous 50mm water seal provides superior odour protection compared to shallower 25mm seal traps, while the high 34L/min flow rate ensures rapid drainage and prevents water pooling.
The 70mm overall height makes this trap suitable for a wide range of low-profile installations, including timber floor constructions, first-floor bathrooms, and retrofit projects where sub-floor depth is restricted. McAlpine's reputation for quality engineering means you're investing in a reliable, long-lasting solution backed by rigorous British and European standards compliance.
