The McAlpine ST90CB10-70 is a water seal shower trap designed to prevent unpleasant odors from entering the bathroom through the shower drain. Its dimensions are 90mm x 50mm and it features a 1½" outlet.

The McAlpine ST90CB10-70 is made of high-quality materials and is built to last. It is also easy to install and maintain, making it a popular choice for both DIY enthusiasts and professional plumbers.

Overall, if you're in the market for a water seal shower trap with reliable performance, the McAlpine ST90CB10-70 is definitely worth considering.
