Is the TempAssure 17T worth the premium over the standard 17-series for a tub and shower?
For most residential tub-shower combinations, the standard 17-series is sufficient — it maintains temperature within plus or minus 3.6 degrees F, which is comfortable and code-compliant. The TempAssure 17T makes the most sense if: the home has long pipe runs with significant temperature fluctuations, the shower will be used by young children or elderly users who benefit from precise temperature consistency, or the installation is for a high-end master bath remodel where the premium is justified by the quality experience.
