The average walk-in tub typically holds somewhere between 40 and 80 gallons of water. By comparison, a standard bathtub typically only holds 25 to 45 gallons of water. When deciding to purchase a walk-in tub, it’s important to understand your hot water heater’s capacity. If your walk-in tub can hold more water than your water heater, you might run
out of hot water before your walk-in tub is filled.
How Long Do Walk-in Tubs Take to Fill?
It all depends on your water pressure and fixtures, but many walk-in tubs can be filled within about 10 minutes. Thanks to FAST FILLTM technology, however, the Jacuzzi® walk-in tubs installed by Bath Expo fill twice as fast as other tubs.
How Quickly Can Walk-in Tubs Drain?
This also depends on your plumbing and the tub, but some discount walk-in tubs can take up to 15 minutes to drain. The Jacuzzi® walk-in tubs installed by Bath Expo drain two times faster than average tubs because of Fast Drain technology, which helps users avoid becoming cold while waiting for their tub to drain.
