How much water does a walk-in tub hold?

If you’re considering a renovation to make your bathroom easier to use with limited mobility, you might be wondering, “How much water does a walk-in tub hold?”

Bathtubs vary in size, so for a precise answer you’ll need to look up your model. However, there’s a ballpark figure we can give you.

How much water does a walk-in tub hold? 

The average walk-in tub holds about 50 gallons of water. However, you don’t have to fill it all the way up.

If your walk-in tub has hydrotherapy jets, your supplier should show you the minimum fill line to operate them. Other than that, how long it takes to fill depends on how much water you like to have during your baths.

What size water heater do I need for a walk-in tub? 

A rule of thumb is you’ll need a water heater tank that’s at least 2/3 the size of your bath tub. Most walk-in tubs range in capacity from 42 to 60 gallons. So, for a 60 gallon walk-in tub, you’d need at least a 40-gallon water heater.

However, if you live with other people who will be using hot water at the same time you bathe, you might want to add another 10 gallons to that figure.

The best thing to do is simply ask your bathroom remodel specialist or the store you’re buying your tub from if your current water heater is large enough.

Do I need a tankless water heater for a walk-in tub? 

No, you don’t necessarily need a tankless water heater for your walk-in tub. However, it may come in handy, especially if you have concerns about using up all your home’s hot water after you fill your bathtub.

It will assist your primary water heater, they’re much more energy efficient than normal water heaters, and have a longer lifespan. They’re also easier to fix, which is another reason to consider them despite being more expensive than a traditional water heater.
