A home dog wash station in a mudroom, laundry room or garage makes bath day easier on your back and your bathroom, but pets need warm, steady water, not a blast of hot water followed by cold. A small tankless heater installed right at the tub delivers lukewarm water instantly and holds the temperature you set. These four are the best tankless picks for a pet washing station.
We compared flow, temperature control, installation and safety using manufacturer specifications and owner feedback. For scored reviews see tankless water heater for pets reviews, or see the best tankless water heater guide for whole-house units; our Editorial Policy explains our process. Always test water on your wrist before bathing a pet.
