Get the power, in your shower. If your power shower doesn’t work, we have the solution. Bristan’s power showers have the power pump built in causing an increase in the flow of water passing to the shower head, this adds an extra perk to your showering experience. Each shower requires a hot and cold-water supply placed above the shower pump, preventing intake of air into the system. These power showers will have you enjoying a sumptuous shower every time.
