Why Use A Laundromat?

No. U save on your light and water bill. Some ppl refer to go to laundromat to all washing at one time. 

My first apartment did not have any place to hook them up. And a lot of renters can afford a few dollars here and there but not hundreds upfront for a washer & dryer.

And the dollar sign goes before the number.

Most apartments do not have laundry facilities. Some new & high-end apts might only have very small units which cannot handle large items such as blankets, comforters, area rugs, etc. If the landlord pays for water, LL does not want to add the high costs of major water use! Most apartments do not have necessary hookups, either, and need rewiring and exhaust vents for the dryer installed. 

If you have checked current prices on appliances, those paying for stove & fridge often cannot afford laundry equipment as well (not even used), especially if they need to do wiring work, install proper vents, etc. Licensed electricians, etc, are not cheap, either.

Practically everybody has to use a Laundromat from time to time, even if they own their home, own washer & dryer, etc. 

Well ran out of water twice this summer. We coped, but if we had been out of clean clothes, we would have gone to the laundromat. And even buying a washer and dryer, getting them delivered and installed may take longer than one would wish.

What does this have to do with taxes?

It's not necessary to use a laundrymat. Clothes can be washed by hand, or a washer/dryer can be bought, and put into a home owner's home.

I own 1 item of clothing that must be washed by hand, but the rest of the clothes I have can either be washed by hand, or I can use a washer, or dryer.

I am considering to buy a mobile home, and buying my own washer/dyer too. Obviously it won't be a big machine like you would see at a laundrymat, and yes, I did go to a laundrymat, so I know how big those machines are. Instead of creating a pile of clothes well more wash would have to be done. I know what you mean about being able to do several loads at once, and that can be done by using a bigger machine.

For people who own houses, or a bigger home then yes this could be an option. Because those people would have more space, and they can buy a bigger washer/dryer.

"Washing machines typically use 350 to 500 watts of electricity, or between 0.35 and 0.5 kilowatts. According to the Otter Tail Power Co., you use your washer for seven to 40 hours per month, depending on how many loads of laundry you do. Your dryer uses between 2 and 20 kilowatt-hours of electricity per month."

If the above information is correct, and I found it online by the way then I believe a bigger bill will go to people who don't know how to reduce their electric bill cost. Currently I am not a home owner, so I am not able to experiment with reducing the cost of electricity, and yes I know there are people who do this, and yes, I have some knowledge of being able to reduce the cost of electricity.

I believe it's dangerous to completely experiment with reducing the cost of electricity. I don't know if I really want to try. Because if I were to make 1 mistake then I think my mistake might kill me if I were to try to reduce the cost of electricity.

First, many of them rent and have landlords who won't allow it.

Second, when you consider the need for the plumbing and electrical work, as well as the water bill and electric bill, it's not always cheaper.

Not everyone lives in a place that is plumbed and wired for laundry appliances.

Why would a renter want to buy these appliances when they don't know where they will be next year or the year after that?

I have laundry facility in my home but occasionally use the laundromat for these reasons:

1)  My machine needs repair;

2)  I am washing super-bulky items like quilts or sleeping bags

3)  I am washing items that have stuff on them I don't want in my septic system - like hairy dog beds or towels used to dry the dog after a bath.

4)  I am washing items that have stuff on them I don't want in my machines - like motor oil, candle wax or excess dye.

If you are renting you do not want to have to move the things every time you move.  They are big.  

Not everyone has the space, or money, to buy them.
