The McAlpine STW12-RB is a resealing shower trap designed to prevent unpleasant odors and gases from entering the bathroom through the waste pipe. It has a water seal of 80mm and a multifit outlet, which can accommodate various plumbing configurations.

The resealing mechanism of the trap ensures that the water seal is maintained even if the trap dries out or the water in the trap evaporates. This prevents foul smells from entering the bathroom and also prevents the build-up of harmful gases such as methane and carbon monoxide.

The trap is easy to install and comes with a removable trap body, making it easy to clean and maintain. The chrome finish on the plastic components gives it a clean and polished look, which is suitable for modern bathrooms.

Overall, the McAlpine STW12-RB is a reliable and effective option for shower installations that require a resealing trap to prevent unpleasant odors and gases from entering the bathroom. Its multifit outlet also allows for easy installation in various plumbing configurations.
