Fixed shower heads are wall mounted or attached to the shower faucet arm with a pivot mechanism. They are usually smaller in size and the simple yet functional design makes them a popular choice for most bath makeovers. A dual shower head on the other hand, combines a fixed and hand-held shower unit in one. Both units can have different size and functions such as spray pattern and flow per gallons giving customers more variation within one product.
