Bathtub Water Usage

Bathtub Water Usage

In this day and age when people are being urged to save water especially in the hot summer months, many look for new and creative ways to conserve that water. One of the more popular methods of water saving is to take showers instead of baths since showers only require from 15 to 20 gallons of water vs the projected average of 45 gallons of water for a bath. Of course, there are many other things to consider when deciding if this is the ideal solution for you.

Size Of Tub

Before making this decision, you'll want to know how large or small your bath tub is. Obviously, the larger your bath tub, the more water it's going to require. Larger tubs are categorised as types of freestanding tubs and of course the old fashioned slipper style tubs as well as the claw foot style tubs. Smaller tubs will often have a step to sit on or be smaller in size or volume compared to the freestanding tubs.

Size Of People

After you determine how much water you'll be using in a tub, you'll want to consider the size of the largest person who will be using the tub. Do you have a strapping young son of 6 foot or taller? Perhaps a spouse or relative that visits often? Or, is your family on the shorter size and only about 5' 10"? All of these questions will need to be considered prior to making this decision.

Factoring In The Gallons Per Minute

Gallons per minute (or GPM) refers to how many gallons of water you'll be using each minute when showering. In order to conserve water you'll need to select a shower head with high pressure but a slow enough water speed to keep your water usage down. Keeping showers timed at shorter lengths will also go far in helping to keep these costs down. For those with longer hair it may take a bit longer to get shampoos, conditioners etc. out of the hair. In any case, everyone should be able to be in and out of a shower within 20 minutes.

Men Vs Women

Normally, a man uses less water in a shower than a woman who must do her hair. In many cases, the woman, doing her hair would use less water in a bath than a shower. She could shampoo and rinse, soak in the tub with conditioner in her hair and then rinse her hair and actually save water by going this route. Standing in the shower she would use more water and it might take longer to get her longer hair shampooed and conditioned than had she taken advantage of a tub filling and done her hair while it was filling.

All Things Considered

Ultimately, keeping to shorter showers of 20 minutes or less and using a low flow shower head with low gallons per minute (GPM) will save you the most water. One easy way to determine this is to take a shower but plug the drain and see if you fill the bath tub or only partially fill the bath tub. If it exceeds the level of water you'd normally use for a bath then you know it is less expensive to take a bath than to shower. Focus on timing and lower flow shower heads and you'll likely find that you've found a great way to save some money on many of your expenses.
